We've just got back from Czechia where we spend 8 days visiting our son and his Czech wife.

We first went to Prague in December 2011 where, in addition to the breath-taking beauty of Old Town Square, dressed up for Christmas, the most abiding memory was the memorial to the two young Czechs, Jan Palach and Jan Zajíc, who killed themselves by self-immolation in Wenceslaus Square in January and February 1969, respectively, in protest against the Soviet-led occupation of then Czechoslovakia in Spring 1968. Soviet-led Russian, East German, Polish and Rumanian forces had occupied the country to depose Alexander Dubček's regime, which had attempted to introduce liberalization and reformed communism more in line with western Social Democracy.

This time, apart from the stunning growth in prosperity that manifests itself in new roads, traffic, good eateries and supermarkets with full shelves and a wide range of choice, mostly since Czechia joined the EU, the most memorable event was a visit to a Museum in the Moravský Krumlov castle near Brno which is the temporary home of a series of immense paintings by the Czech artist, Alphons Mucha, perhaps more famous in the West for his commercial art nouveau designs for chocolate boxes, biscuit tins and soap packages that charcterised the 1920's and 30's.

In Czechia he is better known for his series depicting the 'Slav Epic', or the history of the Slavs, from their legendary origins in the wetlands between the Baltic and the Black Sea to their settled homeland in Eastern Europe.

The story is one of an oppressed people, set about by enemies, forever yearning to be free to live their lives in peace, according to their own customs, culture and tradition, free from interference by more powerful and expansionist neighbours. In the 1920, when Mucha was finalizing his epic, Russia had not emerged as the threat it would later become and was considered part of the Slav family of nations together with Poland and the Southern or 'Jugo' Slavs of the Balkans who had emerged from the ruins of the Austro-Hungarian Empire at the end of World War I.

And underlying this backdrop of interference and meddling, was religion, Catholic, Protestant and Eastern Orthodox, each using their religion as an excuse to wage war and impose foreign rule on the Slavs. Consequently, Czechia is now one of the most Atheist country in Europe, with 37% of the population, second only to France with 40%, openly declaring their Atheism.

This description of Mucha's Slave Epic follows the sequence in which they are displayed in Moravský Krumlov castle, which is neither chronological in the events they depict nor in the order in which Mucha painted them, so bear with me if I flit back and forth from age to age throughout the Middle Ages and the 18th, 19th and early 20th century:

The first of Mucha's Slav Epic:
The Slavs in their Original Homeland - Alphons Mucha (1912)
There is no general consensus of where the Slavic peoples originated apart from some vague reference to between the Baltic and the Black Sea. Tradition has it that the Slavs, an Indo-European people, speaking an Indo-European language, emerged somewhere in Eastern Europe during the 'migration period' between 5th to the 10th century CE, traditionally in Polesia. During this period, The Huns, a Turkic people from Central Asia had moved westward in one of the periodic explosions of Central Asian nomads into Eastern Europe. This precipitated a movement of Germanic peoples, known in German history as the Volkswanderung, when various Germanic tribes such as the Goths, the Vandals and the Franks undertook huge migrations into Western Europe and North Africa (Vandals), into the Balkans, Italy and Spain (Goths) and France (Franks) where they destroyed and replaced the remnants of the Roman Empire.

The picture shows a Slav settlement being destroyed by fire by nomadic slave raiders who sold their captives in the slave market in the city of Kherson on the northern shores of the Black Sea. The giant figure is an old Slavic priest or zhrets, who begs the gods for help. He is propped up by a young man in red (symbolizing war) and a girls dressed in white (symbolizing peace). The painting symbolises the birth of a people born in fear, oppression and destruction, with nomadic Turkic raiders from the East and South and the Germanic Goths from the West. Their only hope is for peace in which to realize their potential, but they are going to need to fight for it.
The "Magic of the Word" triptych
1. Jan Milíč of Kroměříž (1916)
2. Master Jan Hus Preaching at the Bethlehem Chapel (1916)
3. The Meeting at Křížky (1916)
This illustrates a period in Slav national development when, in a period of rising discontent with the corruption and debauchery of the Catholic clergy, they were becoming increasingly disillusioned with the Catholic Church, in a way that presaged the Protestant Reformation some years later.

The left-hand panel depicts the preaching of Jan Milíč, the son of a master weaver from Kroměříž who had risen to the post of notary to King Charles IV of Prague and then to the post of vice-chancellor and canon of St Vitus Church. He fell under the influence of the German preacher, Konrad Waldhausen whom Charles IV had invited to Prague to preach against the 'sinful and immodest ways' of the local citizenry. Milíč also became interested in the teachings of Francis of Assisi and resigned to live a life of poverty and preaching against pride, adultery and greed.

His most notable success was in his conversion of many of Prague's prostitutes. Having begged Charles IV to donate land in Prague Old Town, he built a chapel and a the 'New Jerusalem' monastic shelter for the women. The first picture depicts the construction of New Jerusalem while the women look on and listen to Milíč preaching. The woman with the face covering is meant to symbolize repentance, rectification and doing good deeds.

The central panel of the triptych depicts the last sermon of Master Jan Hus in Bethlehem Chapel in 1412. At the time, Hus was rector of Charles University in Prague. The chapel was the only place in Prague where sermons were preached in Czech at a time when the Catholic Church was determined to protect its monopoly on interpretation of the Bible by forbidding it to be translated into local languages to make it accessible to any literate person, not just priests trained in Latin. Masses were only permitted in Latin.

Hus had been strongly influenced by the teachings of John Wycliffe, Master of Baliol College, Oxford, sometimes called "The Morning Star of the Protestant Reformation" - a title often applied to Jan Hus - who had produced the first English translation of the Latin Vulgate Bible and had argued against the Catholic Triune god and preached against Catholic corruption including the sale of indulgences. His followers were the Lollards, a prescribed heretical sect and Wycliffe was excommunicated although he escaped execution, the usual punishment for heretics.

Jan Hus's followers, the Hussites, eventually became a major Christian sect in Bohemia - the part of Czechia that includes Prague, the forerunner of the Protestant Reformation.

The panel depicts several Prague notables, and people involved in funding and building the chapel. On the left of the picture, near the chapel wall and next to the veiled figure in white, there is Jan Žižka of Trocnov, a courtier of King Wenceslaus IV and Queen Sophia's doorman. In front of him, dressed in black, is the tradesman Kříž who donated part of the land for the chapel and next to him, dressed in red, is Hanuš of Műlheim who obtained the building permit for the chapel and provided funds to build it.

Under the canopy on the right is Queen Sophia, wife of Wenceslaus IV, whose confessor was Jan Hus. Her lady in waiting is modelled on Mucha's wife, Maria Née Chytílová. The hooded figure lurking behind the font is a spy employed by Catholic priests concerned that Hus was preaching against the church's iniquities and the sale of indulgencies.

In 1412, an interdict was declared over Prague, banning all church rites until Hus left the city.

When the painting was completed in 1916, a private house stood on the site of the Jerusalem Chapel which was not rebuilt until 1954 to a design by the architect, Jaroslav Fragner. The chapel interior in the painting does not correspond with the modern chapel.

The right-hand panel depicts the beginnings of the Hussite rebellion. To begin with, the movement had been peaceful and non-violent, seeking to establish the Kingdom of God on Earth, with rallies on hilltops at Hradiště (later Tábor), at Beránek near Vožice and at Oreb near Třebechovice, however it quickly became radicalized by a radical sect from Tábor. On September 17, 1419, a proclamation was read by Václav Korda, a priest from Pilsen, to a rally on Bzí Hill, addressed to all Czechs, telling them "Brethren! Know that the vineyard has blossomed, but the goats want to eat it all up, so don't walk holding a stick but a weapon!". It was a call to arms to defend the Hussite.

The scene depicted is the meeting of the armed group in response to this proclamation that took place on September 30, 1419 on a hill called Na Křížkách. This hill is still called U Křížků, located some 20 Km south of Prague.

The painting is full of symbolism: the dry tree with the white banner signified was and death; the green pine and red banner represent life. The dark sky pierced by lightening signifies the changes that have recently occurred - the Death of Wenceslaus IV, the first defenestration in Prague and Jan Žižka forming the first military division of Hussites. The picture as a whole is a call to arms and a challenge to fight for the truth for which Master Jan Hus had laid down his life.

As usual, a theological difference was shaping up to end in a bloodbath with 'truth' going to the side which did the most killing.

The Celebration of Svantovit on Rügen (1912)
This next painting deals with events preceding the Hussite rebellion, in the pre-Christian era when the Slavs had become too populous for their homelands and so set out to find a new homeland, during the period known as the Migration Period. As early as the 7th Century CE, some tribes settled on the Baltic coast, assimilating with the local Celtic and Germanic people.

Near the Odra estuary to the Baltic Sea is an island called Rügen, the home of the Rani tribe, on which there was a temple to the god Svantovit in the city of Arkona. The painting shows the autumn festival to celebrate Svantovit in which the priests thank the god for the harvest and prophesy the future. In that respect, Arkona was to the Slavs what Delphi was to the Greeks.

In 1168, Christian Denmark launched a crusade against the Baltic Slavs, led by Valdemar of Denmark. They captured the city of Arkona, destroyed the temple and burned down the statue of Svantovit. The top part of the painting symbolises this destruction of the Slavic religion with the Germanic war god, Wödan on the left looking on surrounded by sacred wolves. The figure on the sacred white horse represents the last Slavic warrior as Svantovit takes his sword from his hands. People in chains represent the conquest of the Baltic Slavs by Germanic people.

At the bottom to the left is a bard, as a reminder that all we know of the Baltic Slavs is from oral traditions in myths and legends. In the center is a woman in white with a grey area above her, symbolizing the poor prospects for the Rani tribe while to the right a boy tries forlornly to carve a replacement for the statue of Svantovit.
This painting then records the destruction of an important Slavic religious tradition by crusading Germanic Christians.

The next painting celebrates a high point in Slavic cultural development with Tsar Simeon of Bulgaria (Car Simeon Bulharsky) taking control of a large part of the Balkans in dispute with the Byzantine Empire (the descendant of the Eastern Roman Empire) which had adopted Eastern Orthodox Christianity.
Car Simeon Bulharsky (1923)
The reign of Tsar Simeon at the turn of the 9th and 10th centuries marks the high-point of Bulgarian power and glory. After fighting with his neighbours, Simeon gained control of most of the Balkans and came close to taking Byzantium and so the crown of the Byzantine Empire.

Simeon's reign also marks the birth of Slavic literature.

When Bishop Methodius died in Great Moravia in 885 CE, it sparked a dispute between supporters of Latin and Slavic liturgies. Although Methodius had promoted Gorazd as his successor, Rome imposed Bishop Wiching of Nitra to administer the Moravian Church and banned the use of the Slavic language in worship. Slavic priests were expelled from Great Moravia and most went to Greater Bulgaria, including Clement of Ohrid who became the first Slavic Bulgarian bishop (depicted top left). In the upper right corner is Naun of Angelarij who simplified the Galgolitic Alphabet to Cyrillic - the predecessor of the modern Cyrillic Alphabet.

The painting shows Simeon on a throne in a palace in the capital city of Velká Pereslav, supervising the works of scribes who write down the elders' memories to preserve them for posterity. The available literature is translated here, and monks transcribe a reproduce works of literature. The whole painting illustrates Byzantine richness and opulence.

The next painting is a stark depiction of the aftermath of the battle of Grunwald in which the Slavs were triumphant over the Teutonic Knights, a Catholic order of shock troops charged with spreading the authority of Rome by force of arms. Painted in 1924, it is Alphons Mucha's call for peaceful coexistence of nations.
After the Battle of Grunwald (1924)
In the 12th century, the Teutonic Knights, an expansionist crusading order, settled in the then Slavic territory of Prussia and quickly got into territorial dispute with its neighbours. In 1409, war broke out between the Teutonic Order and Lithuania in which Poland became involved on the side of Lithuania, supported by a mercenary corps from Bohemia and Moravia led by Jan Sokol from Lamberk. The corps also probably included Jan Žižka from Trocnov.

The painting depicts the scene the morning after the bloody battle in which the Teutonic Order was defeated. King Władysław II Jagiełło covered his face in pain at the unnecessary deaths and the immense sacrifice of his warriors. Under the hill is the body of the Grand Master of the Teutonic Knights, Ulrich von Jurgingen with a cross on his chest. In the background the Orthodox Patriarch blesses the fallen, especially the Smolens who were in the front row in the battle.

The numerous white cloaks with black crosses symbolize the broken power of the Teutonic Order and how Poland and Lithuania had defended their freedom.

In the next painting Alphons Mucha celebrates the 9th century introduction of the Slavonic liturgy at Great Moravia as a symbol of Great Moravia's independence from Bavaria.
The Introduction of the Slavonic Liturgy at Great Moravia (1912)
The Great Moravian Empire had successfully faced the onslaught of the Germanic Franks, but the local church was subordinate to the Bavarian bishops. Moravia's ruler, Prince Ratislav realised that he needed to assert the independence of the Moravian Church to strengthen to nation's position as a united entity, so, in 860-861 CE he asked Pope Nicholas I for help. However, this was refused so Ratislav turned to the Byzantine Emperor Michael III with a request to send teachers to Moravia who would be capable of spreading the faith in a Slavic language.

Amongst the teachers sent by Michael III were Constantine (who later took the name Cyril) and his brother Methodius from Thessaloniki (Salonica). They compiled a new script, Glagolitic (the predecessor of Cyrillic), and used it to translate the Gospels. Although they face stiff opposition from the Latin priests, they eventually prevailed and Old Slavonic became an equal ecclesiastical language in Great Moravia. The Pope eventually appoints Methodius as Archbishop, giving him authority over Bishop Witching of Nitra.

The painting is set in the Great Moravian capital, Velehrad. It depicts Price Svatopluk sitting on a high stool with bishops and nobles before him. The deacon is reading a letter from the Pope appointing the new Archbishop Methodius. A Frankish knight watches him humbly. The Rotunda in the background represent the Church of St George in Thessaloniki with Methodius at the head of a procession of his disciples.

The group at the top of the painting represents the violent spread of Christianity by the Franks. At bottom left, Cyril, in a cowl, protects the Moravians from heaven. At top right, Mucha uses four figures to symbolize the liturgical connection of Great Moravia to Kievan Rus with St. Olga and her husband Igor, to Great Bulgaria with St. Boris and his wife.

The two figures in the middle, sitting on a sword shaped like a ship, are the sons of St. Vladimir of Kyiv, Gleb and Boris, patrons of sailors and protectors of merchants. This is Mucha's metaphorical depiction of Christianity as a port to which all Slavic nations gradually arrive. The prominent young man with a circle and clenched fist in the foreground represents strength and cohesion.

While the northern Slavs of the Baltic and south into Bohemia and Moravia (Modern Czechia) were consolidating their position and unifying around a Slavonic liturgy and asserting their independence from the Latin liturgy and the Germanic tribes to the West, the southern Slavs of the Balkans, especially Serbia, were struggling to become unified. They lived in valleys separated by high mountains and were dominated by the Byzantine Empire until the 12th century when Stefan Nemanja succeeded in unifying most of the tribes in the Drina basin and Montenegro. In the 14th century, Stefan IV Dušan incorporated more of Serbia, southern Macedonia, Albania, Thessaly and the Belgrade area into an empire that stretched from the Danube to the Gulf of Corinth. In 1349 he issued a Code, creating a feudal society giving rights and power to feudal lords over the peasants. In 1346 he had been crowned Tsar of Serbs and Romans (The (Greek) Byzantines always called themselves Romans) in Skopje, making him, de facto, Emperor of the Eastern Roman Empire, a high-point in Slavic political power.

In the same ceremony, his son, Stephen V. Uroš, was crowned king of all Serbian and costal territories.

The next painting depicts the moments immediately after the coronation in Skopje.
The Coronation of Stefan Uroš Dušan
At the head of the procession, the nobles carry the tsar's helmet, shield and sword, symbols of his military power, and the chancellor carries the state seal, the symbol of his political powers. The tsar dressing in lavish robes carried a scepter, also a sign of his powers.

His son, Steven V. Uroš follows in his footsteps while girls with branches sprinkle flowers in the path. The Sebian patriarch (Senior Eastern Orthodox Archbishop or Pope) follows behind.

The girl with a long braid and floral crown in the foreground, is typical of Mucha's elaborate Art Nouveau style.

In the 13th century, under Wenceslaus I's son Ottokar II of the Přemyslid dynasty, Czechia became a major power on the European stage. The town of Kutná Hora provided an abundance of silver resulting in unprecedented prosperity. Due to his wealth and generosity, Ottokar was known as the 'Golden King' and Czechia expanded its empire in Austria to include Styria, Egerland, Carinthia and more.

The next painting depicts the marriage of Ottokar's niece, Kuningunde of Brandenburg to the second-born son of his long-time rival, the Hungarian Béla IV, also called Béla, as part of the political machinations that took place following Ottakar's defeat of Béla IV in battle and his annexation of Bratislava.
King Ottokar II of Bohemia. (1924)
Ottokar II had a major long-time rival in Béla IV of the Hungarian Árpád dynasty, culminating in the Battle of Kressenbrunn. Ottokar's 'iron cavalry' which earned him his alternative nickname, the 'Iron King', prevailed and Béla's forces fled the battlefield in chaos. Taking Bratislava forced Béla to negotiate a peace agreement.

To consolidate this resulting peace, Ottokar divorced his wife, Margaret of Bebenburg and married Béla IV's granddaughter, Kunigunda. He also arranged the marriage of his niece, Kunigunde of Brandenburg to Béla IV's second-born son, Béla. The latter wedding took place on October 25, 1264, on Žitný ostrov, an island in the Danube in what is now Slovakia.

The painting shows influential European rulers of the time in a tented city specially built for the wedding. Ottokar is shown warmly welcoming his recent rivals. The guest list includes King Daniel of Galicia and the Serbian King Stefan Uroš I with both his sons Dragutin and Milutin, the Duke of Croatia, Bosnia Transylvania and Bulgaria, princes, counts and knights from Germany, Poland, Eastern Europe and the Balkans.

Ottokar had a serious claim to the throne of Holy Roman Emperor. However, the electors, overwhelmingly German, chose the inconsequential Prince Rudolf I of Germany from the house of Hapsburg.

In 1273 the peace gained through political marriages broke down and the Hungarians invaded Moravia. In 1276 the Holy Roman Empire attacked and Ottakar was forced to cede numerous territories to Rudolf I. Finally, Ottokar had to face civil war when the Czech nobles rebelled, eventually being killed in battle at the Battle of Marchfield on August 26, 1278.

The Unity of the Brethren was a religious denomination, originating in the later 15th century in response to corruption in the Roman and Ultraquist churches. The Ultraquist Church was the largest sect of the Hussites after they split into factions. They preached that the Eucharist should consist of both bread and wine and be administered to the laity (one of the Four Articles of Prague of the original Hussites). At the time, the Roman Catholic Church insisted that only priests could receive communion wine. Of the Hussite factions, the Ultraquists, also known in Czechia as the Calixtines were closets to Rome and eventually allied themselves to Rome in suppressing the more radical Hussites, the Taborites and Orphans at the Battle of Lipany in 1434.

The Brethren were influenced by Humanism and consequently moderated their former strict approach to education, producing some of the best schools in Czech lands.

The next painting depicts one of the most famous Brethren schools in Mucha's hometown of Ivančice: the aristocratic Law School. He shows the town as it was in the 16th century, with city walls and a church tower. Karel the Elder of Žerontín, then lord of Rosice and Náměššť nad Oslavou supported the institution. A number of distinguished people taught there, including Jan Blahoslav from Přerov, known for his translation of the New Testament from Greek into Czech. This translation was considered a gem of Czech literature and the Brethren set up a printing press at their church in Ivančice to print copies of it. The press was eventually transferred to a Romanesque fortress near Kralice. Because of that relocation, Karel the Elder's translation became known as the Kralice Bible

The following painting shows the classes being taught at the Brethren school in nature. The location of this school is today known as "Va Sboru", "At the Brethren’s place".
The Brethren School at Ivančice (1914)
The location of this school is today known as "Va Sboru", "At the Brethren’s place".

The lessons are interrupted by a visit from Karel the Elder of Žerontín who is shown sitting on the right, under the shelter, looking at copies of the Bible. His second wife is nearby. Her face shows that she was ill and had suffered illness all her life. There is a printing press on the right edge of the painting. A young man, with the face of Alphons Mucha reads from the Bible to a blind man. The fruitful prosperity that followed the hot summer of the Hussite wars is symbolized by a sunny autumn scene and abundant harvest. The swifts circling the church tower symbolize that the Unity Brethren will soon need to leave on long journeys. After the Battle of White Mountain (1620) many left to seek refuge abroad. The Battle of White Mountain was an early battle in the 30-years war from which the Czech people were to suffer horribly as the Catholic Church tried to suppress the Protestant Reformation. The battle ended the Bohemian Revolt and gave the Germanic Hapsburgs a supremacy that was to last for 300 years, until the end of World War I and the dismantling of the Austro-Hungarian Empire.

In the next painting, Mucha comes forward to the 19th century and events in Russia.

Russia had fallen behind both politically and economically, only catching up with developments in the West in the 19th century. Defeat in the Crimean War (1853-1856) and several peasant uprisings, under the influence of the political developments in France where the monarchy had been overthrown and a nation built ostensibly on the principles of Liberté, Égalité, Fraternité (freedom, equality and brotherhood) forced the Russian government to implement changes. The Emancipation reform laid the foundation for industrial development with freedom for the working class who were now free to leave the countryside where they have been tied by feudal laws, to move into the industrial cities.

On February 16, 1861, Tsar Nicholas II issued a proclamation abolishing serfdom, so freeing 47 million serfs from the Mediaeval feudalism that tied them to the land of their feudal overlords.

This event is depicted in Mucha's painting set in Red Square, Moscow in front of St Basi's Cathedral.
The Abolition of Serfdom in Russia (1914)
The Kremin towers loom in the background. To the right of the temple, built in the 16th century by the first Russian Tsar Ivan the Terrible, is a round tribune from which the Tsar's order abolishing slavery was announced on March 5, 1861. The village and Townspeople remain in the square to deal with their new freedom in their own way. Some are clearly rejoicing while others are unsure what to expect.

Above the towers of the Church of Vasily the Blessed, the first rays of the sun symbolize the dawn of freedom, gradually penetrating the fog. Mucha painted this after a trip to Russia in 1913. He originally intended to paint it as a glorious event but changed it when he realised the oppression of ordinary Russian people and their actual standard of living. This was just 4 years before the October Revolution that overthrew the monarchy and replaced it with Soviet Communism.

We're back now to the 15th century, to another significant figure in the cultural development of the Slavic people, Petr Chelčický, the influential religious thinker and pacifist from the village of Chelčice near Vodňany. He knew the leaders of the Hussites personally, including Jan Huss.

His religious beliefs included the complete equality of all Christians which led him to conclude that, to be rewarded in the afterlife, people living in secular coexistence should endure evil without resistance. This set him apart from the other Hussites who taught that they had to be prepared to defend truth and religion with force of arms if necessary.

The next painting depicts an event in the autumn of 1420.
Petr Chelčický at Vodňany (1918)
In autumn, 1420, the victorious Hussite army had marched back from Prague to southern Bohemia when a powerful local feudal lord Oldřích of Rosenberg, an implacable enemy of the Hussites since his defeat at Tàbor sacked the town of Vodňany with a band of mercenaries. He murdered and banished supporters of the reform movement, demolished the city walls and installed a new, anti-Hussite town council. The Hussite army set out from their camp near Písek and stormed Vodňany to retake it from the invaders.
The painting shows smoke rising from the plundered and burning city in the background. The inhabitants flee to the pond near the Chelčice village and lay their dead and wounded on its shore. Their faces reflect hopelessness, fear and anxiety: on the left is a crying little girl who was able to save only the dishes in the basket and a caged bird. Next to her, a young women mourns the death of her loved ones. The event evoked an overwhelming desire for revenge, but Petr Chelčický intervenes to proclaim his faith in the power of love, tolerance and forgiveness. Holding the man’s raised fists, he tells him "No, you must not repay evil with evil because then it multiplies, and it does not end. Let evil perish!

In 1457, following Chelčický's teaching, Jan Řehoř founded the Unity of Brethren in Kunvald.

In 1566 Ottoman Turks invaded Hungary with a large army and in August that year they laid siege to the town of Szigetvár which was defended by troops of the Croatian Royal Army under the command of the Ban of Croatia, Mikuláš Ŝubić Zrinski, a descendant of the old noble house of Ŝubić Bribirski. He had risen to fame by defending his homeland against the Ottomans and in 1863 he was appointed commander of the royal army at Szigetvár.

Though vastly outnumbered the defenders fought fiercely for every part of the city, palace and old fortress. Ultimately, Zrinski and his garrison were defeated, but their courage and the enormous casualties they inflicted on the Ottomans postponed the Ottoman campaign in the west for several years.

The painting depicts the last moments of the siege when the Turks had already taken the city.
The Defence of Szigetvár by Nikola Zrinski (1914)
The painting shows the palace and old fortress engulfed in flames. Zrinski delivers a fiery speech as he prepares what remains of the garrison for a last charge. Exhausted fighters lay aside their heavy gear, so it doesn't slow them down.

The righthand side of the paintings shows a gunpowder magazine that the defenders don't want to fall into enemy hands. The commander of local women lights a torch which she will throw into the magazine, destroying it and her women with it. Other women follow her onto the scaffolding because they prefer death to captivity and slavery.

The black column dividing the images symbolises the explosion of the fortress and the nobility of the terrible sacrifice: the lives lost defending freedom.

During the Hussite era one battle stands out for the bravery with which a Hussites army, led by Jan Žižka of Trocnov, withstood an attack by the mercenary army of the Holy Roman Emperor, Sigismund.

Sigismund was the younger brother of King Wenceslaus IV, and after Wenceslaus’s death, Sigismund laid claim to the Czech throne and laid siege to Prague. Jan Žižka set out from Tábor to try to raise the siege. As an experience military leader, he realised the strategic importance of Vítkov Hill, so he fortified the road that led from the only access to Prague not occupied by Sigismund's forces, the Poříčská gate, under Vítkov Hill to Tábor, by building two log cabins surrounded by a small moat and a wall. He defended this position personally with 26 men, two women and a girl.

Sigismund's armies launched an attack on Prague on Sunday, July 14, 1420, with the cavalry from Meissen storming Vítkov Hill. They managed to reach the log cabins where they met heroic resistance from the defenders. The uneven battle raged for some time until the situation became desperate until the people of Prague used the Poříčská gate to attack the cavalry from the rear. In the ensuing panic and confusion, many of the enemy perished as they tried to flee down the steep slope.

This painting depicts the scene after Žižka and his fighters descend victoriously from Vítkov Hill.
After the Battle of Vítkov Hill (1920)
The priest from Tábor stands at the field altar holding the host; other priests lie on the ground in deep humility. A man sitting on a wicker basket is accompanying the prayer by playing a field organ. On the left of the road a young warrior bandages his wounds, and a woman is breast-feeding her baby - symbolizing a new generation. Poříčská gate and the city walls can be seen on the left in the background, brightly lit by sunlight. Vítkov Hill looms on the right and Žižka, in a red cloak, stands deep in thought and thanks God for his victory. In front of him are captured weapons and equipment.

A notable figure in Slav cultural history is the teacher and philosopher, Jan Amos Comenius (Jan Amos Komenský), known as the 'Father of Education'. His parents were members of the Unity Brethren, a pacifist Hussite faction. The Komenský family took its name from the village of Komňa near Uherský Brod, where Jan's father, Martin, worked as a miller for his brother. Jan's birthplace is uncertain, probably either Uherský Brod or Nivnice, but around the time of Jan's birth, his family moved to Uherský Brod where they belonged to the wealthy burger class and became important members of the Unity Brethren who helped Jan attend their school in Přerov. He graduated from colleges in Herborn and Heidelberg. During his studies he began writing 'Treasures of the Czech Language' and prepared Theatrum Universitatum Rerum (The Treasures of the World), an encyclopedia for young people.

After completing his became a priest and teacher studies he returned to the Přerov school and later became rector of the Brethren school in Fulnek. After the Battle of White Hill in 1620, which resulted in victory for the Germanic Hapsburgs and the suppression of the Slavs which was to last until the end of World Ward I in the form of the Austro-Hungarian Empire, executions of Hussites took place in Old Town Square and a warrant was issued for Jan Komenský's arrest.

Heeding the warnings of Karel the Elder of Žerontín he went into hiding at Šternberk on the Žerontín estate, but then had to flee from Moravia to Bradýs nad Orlicí.

Following the issue of the Renewed Provincial (Land) Ordinance which effectively abolished Czech independence from the Hapsburgs and made Catholicism the only legal religion, Jan Komenský went into permanent exile, first to Leszno in Poland, then to England, France, Sweden and Hungary and finally back to Leszno. The Peace of Westphalia, the treaty that ended the 30-years war, gave the Hapsburgs dominion over Czech lands and meant permanent exile for Komenský. While in Leszno he wrote a major work, 'The Last Will and Testament of the Dying Mother: The Unity of Brethren, in which he called on Czechs not to lose hope for their eventual independence, but in 1655 he declared his support for Protestant Swedish troops who had invaded Poland, for which his house was burned by Polish Catholic partisans, destroying his manuscripts including a 'Pansophia' (encyclopedia) on which he had been working and his 'Treasures of the Czech language, and he went into exile in Holand where he remained until his death in 1670.

The painting by Mucha shows him at the end of his life looking across the sea, yearning for his homeland.
Jan Amos Komenský (1918)
The painting shows Jan Komenský strapped to a chair on the seashore where he often went to reminisce about his Czech homeland. His friend's gesture and the grief of his wife and others signify that this is his last days before his death on November 15, 1670. He is buried in Naarden which can be seen silhouetted in the distance.

We go back now to the 15th Century to another significant figure in Czech history - George (Jiří) of Poděbrady "King of Both People" (1458-1471). This painting illustrates an event in his life.

Zdeněk Kostka of Postupice and Prokop Rabštejn, allies of King Jiří, delivered a message to Pope Pius II in Rome, requesting that he confirm the 'Basel Compact' (an agreement that regulated the relations between the Hussites and the Catholic Church). But Pius III did not take kindly to it. Instead, he sent a delegation to Prague demanding that King George, his family and the whole nation renounce the Hussites and confirming that he would not recognise the Basel Compact.

The painting shows King Georg's reaction to the Pope's demands.
The Hussite King Jiří of Poděbrady and Kunstat (1923)
King Jiří received the Pope's delegation in the King's Court in Prague's Old Town during the Diet (Parliament). His reaction to the Pope's demands is furious as he rises from his chair, knocking it over in the process and exclaiming, "I do not recognise the Pope as judge over my conscience, my family, or my nation!". The papal envoys are forced to stand as they were not offered seats, to mirror the fact that Jiří's delegates were made to stand before Pius II in Rome.

Several historical figures are represented in the painting. The five-petalled rose at the back marks the lord of Rosenburg, a member of the royal council and ruler of southern Bohemia. Sitting opposite is Archbishop Jan Rokycana, with a cross on a purple robe. In the right corner is the most famous court jester in Czech history, Brother Paleček, in a fool's cap, a wise and educated man who renounced all privileges to advise the king. To his left a boy closes a book inscribed 'Roma' to symbolize the end of negotiations between King Jiří and the Pope.

At the end of this audience, the king dismissed the papal envoys. The next day he arrested and imprisoned the permanent representative of the Czech kingdom to Rome, Fatinus de Valle, who had returned to Prague with the Pope's envoys for betraying and misrepresenting the interests of the Czech kingdom. The Pope retaliated by anathematizing King Jiří (i.e., excluding him from thew society of the faithful because of heresy) and refused to recognise him as King of Bohemia.

Jiří remained on the Bohemian throne for a further 10 years until his death in 1471, aged 51.

Forward now to the 19th century to an event that marks the bid for independence from the Hapsburgs that the Czech's lost in the Peace of Westphalia that ended the bloody 30-Years War between Catholics and Protestants in Central Europe.

After a period of recatholicization, centralization and Germanization which reached a peak in the 18th century under Maia Theresa and Joseph II of Austro-Hungary, with an attempt to suppress even the Czech language, nevertheless a Czech national revival flourished. The people of Prague fought hard to restore their cultural and national identity and, at the end of the 19th century, a progressive youth group, the Omladina, had formed. The movement was accused of high treason and, in an attempt to suppress it in 1894, 76 people were prosecuted and 68 of them were sentenced to a total of 96 years in prison. Among them were future representatives of political and cultural life such as Alois Raší, Karel Stanislave Sokol, Stanislav Kostka Neumann and others.
The Oath of Omladina Under the Slavic Linden Tree (1926)
In this highly symbolic painting Mucha sets the scene in and beneath the sacred linden tree, based on a real tree in Žamberk region. Mother Slavia is seated in the fork of its branches with young people kneeling before her swearing allegiance to the nation and mutual cohesion. To the left in the background stands an old man with a huge grey moustache, a figure from the history of Serbia, as a reminder that a similar also existed there. A Sokol member takes the oath on the right. The Sokol movement (Czech: [ˈsokol], falcon) is an all-age gymnastics organization first founded in Prague in the Czech lands of Austria-Hungary in 1862 by Miroslav Tyrš and Jindřich Fügner. It was based upon the principle of "a strong mind in a sound body". Sokol, through lectures, discussions, and group outings, provided what Tyrš viewed as physical, moral, and intellectual training for the nation. This training extended to men of all ages and classes, and eventually to women. It quickly became associated with Slav cultural identity.

Some of the faces are deliberately left blank as Mucha did not want to portray the politicians of the day. This period was when criticism of Much's work was at its height, and this may have discouraged him from completing this work.

The girl playing the harp in the lower part of the scene is modelled after Mucha's daughter Jaroslava; the boy on the right on his son, Jiří. On the right an old man sings about the famous deed of his ancestors and on the far right, painted before it gained its notoriety as the symbol of fascism, is a swastika - a symbol of the sun in motion worshipped by ancient Slavs and other pagan nations.

The next painting in the series is of the interior of a temple on Mount Athos, in Greece. Although not strictly Slavic, Mount Athos has huge spiritual significance to Orthodox Christians, the predominant religion of some Slavic people, particularly Russians and some Balkan peoples.

Mount Athos is the easternmost of three peninsulas projecting into the Aegean from Khalkidhiki. The whole peninsula belongs to the Orthodox monastic state and comprises some 20 monasteries with about 2,000 monks. Its significance derives from it being the centre of Orthodox Christianity during the Turkish Moslem occupation of Greece and the southern Balkans.

According to legend the Virgin Mary found refuge there and Athos is traditionally her last resting place. In 1045, the Byzantine Emperor Constantine IX decreed that no female may set foot on the entire peninsula, not even female animals, except cats.

The painting represents the interior of one of the Athos Temples, the apis with the mosaic of the Virgin Mary.
Mount Athos (1926)
On the far right, rays of sunlight enter the temple, illuminated by numerous candles. Priests stand before the iconostasis and let pilgrims kiss the holy relics. Cherubs hovering in the bright light carry models of four other Orthodox monasteries: Serbian Hilander, Russian St. Panteleimon, and Bulgarian monasteries Zograf and Vatopedia. Behind the cherubim, we see portraits of the four heads of these monasteries. In the foreground is a young man supporting a blind old man - The model for the young man was Mucha himself.

The final painting in the series, and the summary of the entire Slav Epic, is the Apotheosis of the Slav History.
Apotheosis of the Slav History (1926)
Four colour section the scene. At the bottom right the colour is blue, symbolizing antiquity and the Slavs in their homeland when they worshipped pagan gods. The old pagan priest, Zhrets, presents a burnt offering to the gods.

In the upper third, the colour is red, commemorating the famous moments in Czech history - the most important Czech rulers - Přemsyl Ottokar II, Charles IV and the last Czech king, Jiří of Poděbrady - and the reformation ideas of Jan Hus and the Hussite movement.

Under the red is a black rection symbolizing lost battles and the period of oppression of the Slavs: raids by Franks, Avars and Turks and 300 years of suppression of the Czech language after the Battle of White Mountain.

But the largest area of the canvas is painted yellow - the colour of joy and freedom. The First World War ended in 1918, and the Austro-Hungarian and Ottoman Empires were dismantled so many Slavic nations achieved freedom. At the bottom left, people welcome legionnaires returning home and women in national costumes knit garlands and prepare flags for the celebration of independence. On the right, an old man gives thanks that he has lived long enough to experience freedom. The flags of the victorious powers flutter in the background. On the left are representatives of the Slav nations.

The figure of a young Slavic man dominates the upper part of the painting. His arms are spread wide to show he is finally free. He holds a wreath of victory and unity with ribbons of a Czechoslovakia tricolour tied to them. The image ends with a rainbow, symbolizing the most important idea of the entire Slavic Epic cycle~: peace between nations.

Of course, these paintings were completed in the years immediately following WWI and before WWII and its aftermath when the Slavic nations were again subject to foreign domination. It was to be a further 70 years or so before the Slavs finally became free and freely joined with other European nations in the European Union. As a result of the cultural history of Czechia, and its sorry experience of the blood-soaked struggles between competing religious ideologies and of religion providing the excuse for repression and denial of freedom of conscience, Czechia is now second only to France in Europe, in the proportion of its citizens who openly reject religion altogether.

Ten Reasons To Lose Faith: And Why You Are Better Off Without It

This book explains why faith is a fallacy and serves no useful purpose other than providing an excuse for pretending to know things that are unknown. It also explains how losing faith liberates former sufferers from fear, delusion and the control of others, freeing them to see the world in a different light, to recognise the injustices that religions cause and to accept people for who they are, not which group they happened to be born in. A society based on atheist, Humanist principles would be a less divided, more inclusive, more peaceful society and one more appreciative of the one opportunity that life gives us to enjoy and wonder at the world we live in.

Creationism in Crisis - A Scimitar-Toothed Cat From Texas From At Least 2000 Years Before 'Creation Week'


In the fossil specimen that is the subject of this research paper, two teeth are visible breaking out at the bottom: an incisor, and the tip of a partially-erupted canine. The scale bar at the top right of the image is 1 centimeter.

“Ugly” Fossil Places Extinct Saber-Toothed Cat on Texas Coast | Jackson School of Geosciences | The University of Texas at Austin

Paleaontologists have shown that, what looked like a piece of rock, discovered on a Texas beach about 60 years ago, contains the skull of a young scimitar-toothed cat or Homotherium, that lived at least 12,000 years ago.

The skull was found on McFaddin Beach, south of Beaumont, by Professor Russell Long, of Lamar University, but was donated by U.S. Rep. Brian Babin, a former student of Long’s who worked for 38 years as a dentist.

Because the skull is that of a young Homotherium, the teeth are not fully erupted, so they have been preserved in the rock, in the skull, instead of being broken off, making identification possible.

The significance of the find, which would have originated in the now-submerged neotropical strip of land that acted as a corridor for species to migrate between Texas and Florida during the Pleistocene, is that it helps build a picture of the ecosystem in that coastal strip, where Homotherium would have been an apex predator.

The team of palaeontologists, led by John Moretti from Jackson School of Geosciences, Texas University at Austin, Texas, USA, included scientists from the Department of Biological Sciences, North Carolina State University, Raleigh, North Carolina, USA, the Department of Earth Sciences, University of Oregon, Eugene, Oregon, USA, and Sam Houston State University, Huntsville, Texas, USA. They have published their finding in the American Association for Anatomy journal, The Anatomical Record and describe it in The University of Texas Jackson School of Geosciences news release:

Malevolent Designer News - How Creationism's Divine Malevolence Uses Sneak Tactics To Increase The Sufferring In The World


U of T researchers discover ‘trojan horse’ virus hiding in human parasite | Donnelly Centre for Cellular and Biomolecular Research
Toxoplasma gondii
The parasite, Toxoplasma gondii, is already notorious for manipulating the behaviour of its various hosts in ways which are highly detrimental to the host but highly beneficial to the parasite. For example, mice infected by it are positively attracted to felines - the primary host of the parasite - as a strategy for getting into the feline gut, where the sexual phase breeds and multiplies rapidly to produce oocytes which are excreted in the feline's faces, to be ingested by their secondary hosts, including humans. Chimpanzees, another secondary host, is manipulated by the parasite to crave the scent of leopard urine. The moods changes that infected Human experience may be a modified form of the chimpanzee behaviour, inherited from the common ancestor.

As though that wasn't embarrassing enough for devotees of the god whom they believe designs all living things, an international team of scientists led by researchers at the University of Toronto has found a new RNA virus that they believe is hitching a ride with Toxoplasma gondii which acts as a Trojan horse to gain the virus access to its hosts.

The difference being that, unlike the real Greeks who left what looked like a giant wooden effigy that the defenders thought was some sort of departing offering to their gods, so took into Troy willingly, only for the soldiers inside to come out at night, open the city gates and let the returning Greeks take the city, creationism's nasty little designer doesn't even make toxoplasma gondii look like an attractive gift, but sneaks that in too, in contaminated food and general environmental dirt and dust, that can get picked up on fingers.

In a paper that will have creationist cult leaders wracking their brains for a way to misrepresent or blatantly lie about to their willing dupes, a team of scientists led by Professor Kateryna Makova, Verne M. Willaman Chair of Life Sciences at Penn State University report that they have completed a detailed 'end-to-end' analysis of the sex chromosomes of five great ape species - bonobo, chimpanzee, gorilla, Bornean and Sumatran orangutan and one lesser ape - the siamang - and are now able to compare these with the human sex chromosomes, from a similar analysis completed in 2022-23. The team used the same experimental and computational methods as was used for the human chromosome analysis.

Their findings are published, open access, in the journal Nature and are described in a Penn State, Eberly College news release:

Catholic Hypocrisy News - Pope Lets His Mask of Tolerance Slip As He Abuses Gays in 'Private'


#
Too much 'Fagottiness' in Seminaries - Pope Francis
Pope apologizes after being quoted using vulgar term to describe gay people

In an unguarded moment, for which he has had to apologize, Pope 'Mr. Nice Guy' Francis, revealed the hypocritical difference between his private and public declarations.

Trying to give the Catholic Church a more tolerant and understanding face, in place of the bigoted and judgmental church of his predecessors, that had been driving decent people away, and aware that many Catholic Priests are practicing homosexuals, Pope Francus has previously advocated tolerance and understanding, whilst falling short of allowing same-sex marriages in Catholic churches and ordaining openly gay priests.

But that mask of kindly affability and tolerance was revealed to be a lie intended to deceive when Francis let slip his true feelings when asked if he would allow gay men to enter seminary to be trained and eventually ordained as Catholic priests.

He replied (in Italian):

Seminaries are already too full of “frociaggine”.


This translates as 'faggotiness' and is an especially abusive term for gay people in Italy.

Creationism in Crisis - How The Blundering 'Designer' Has Muddled Up Our Genomes


Genetic mosaicism more common than thought | Max Delbrück Center

What's your genome?

According to recent findings by researchers at the Max Delbrück Center and the European Molecular Biology Laboratory, just published, open access, in the journalNature Genetics, it all depends on which of your cells we look in.

You might think that the replication process, as our cells divide during growth and development, and to replace old, damaged and worn-out cells, would be perfect if designed by a perfect, omniscient designer, but apparently not. And as we age, the mistakes accumulate until we are a mosaic of different genomes, contributing to diseases caused by genetic abnormalities, including cancers.

On the other hand, this is exactly the sort of thing that a utilitarian, evolutionary process, where a suboptimal process will be retained if it gives more descendants that what went before, can be predicted to produce.

How the team discovered this is described in a news release from the Max Delbrück Center:

Between 2,000 and 2,500 years before creationists believe their little god created a small universe consisting of a single, small flat planet with a dome over it, in the Middle East, human beings were hunting a now-extinct elephant on the shores of Tagua Tagua Lake in Chile, South America. By then, humans had migrated out of Africa, spread across Asia to the land bridge between Siberia and Alaska, and from there into North America, down through the Panamanian Isthmus, or by coastal spread, down to South America. Elephants had preceded them probably by several thousand years.

The evidence for this is presented in a paper in PLOS ONE by Rafael Labarca of the Pontifical Catholic University of Chile and colleagues.

Creationism in Crisis - The Evolution of the 'German' Cockroach Happened Just 2,100 Years Ago.


German cockroach, Blattella germanica
Virginia Tech entomologist sheds light on 250-year-old mystery of the German cockroach | Virginia Tech News | Virginia Tech

The origin of the so-called 'German' cockroach, which has nothing especially to do with Germany, has been something of a mystery, as it is unknown outside human habitation. It is what is known as an obligate, commensal species which, like the barn swallows, house mice, human lice and bed bugs, has co-evolved with human culture to live in and on humans and their buildings.

They neatly illustrate how speciation occurs when a population learns to exploit a new resource and then becomes genetically isolated from its parent population and so evolves over time into a new species.

Creationism in Crisis - Biologists Show Repeated Evolution in Stick Insects


On Repeat: USU Researcher Observes Recurring Evolutionary Changes, Over Time, in Stick Insects

Creationists will tell you that the Bible is the 'complete and inerrant' record of the history of life on planet earth and an accurate scientific description of the life on it, and yet it's so inadequate that they've had to supplement it with all manner of fanciful additions to make any sense of it and to make it look slightly more connected to reality.

They then get themselves into a hopeless muddle trying to define a 'kind’, so it conforms to their nonsensical taxonomy. They will tell you one 'kind' can't interbreed with another 'kind' and then need to use a different definition of 'kind' when you mention hybrids, ring species and other evidence of slow divergence over time as barrier to hybridization and genetic remixing evolve, before what science recognises as genetically distinct genera and species.

In any social media group or creationists disinformation site, you'll see a typical double-think approach to evolution: on the one hand we'll be assured that there is no evidence for evolution (based on some childish parody definition of evolution); on the other hand, you'll be assured that, after two of each 'kind' of animal got off the mythical Ark, they underwent a period of warp-speed evolution, producing several, entirely new taxons each generation in different parts of their range to give us the millions of different families, species, sub-species and varieties we see today, which, coincidentally, no-one reported noticing, not even the people who left rock and cave paintings recording what they saw in the world around them several thousand years ago.

But of course, evolution is what it has always been since biologists gained insight into how life changes in response to environmental change - change in the frequency of different alleles in the population over time.

These changes may or may not include new structures or morphology that taxonomists base their classifications on, and they may or may not include changes in coloration (which is a morphological change just as much so as is a new structure).

Here, for example, is the recent discovery by a team lead by Zachariah Gompert of the Department of Biology, Utah State University, Logan, UT, USA, that the stick insect species, Timema cristinae, has had several predictable, repeats of the same pattern of evolution in response to cyclic changes in their environment.

The species occurs in two colour forms - a uniform green, which cryptically camouflages it as leaves of the Californian lilac shrub, Ceanothus spinosus, and a green-striped form which cryptically camouflages it as the leaves of the chamise shrub, Adenostoma fasciculatum.

What the team discovered is the subject of both an open-access paper in Science and a news release from Utah State University:
A longstanding debate among evolutionary scientists goes something like this: Does evolution happen in a predictable pattern or does it depend on chance events and contingency? That is, if you could turn back the clock, as celebrated scientist Stephen Jay Gould (1941-2002) described in his famous metaphor, “Replaying the Tape of Life,” would life on Earth evolve, once again, as something similar to what we know now, or would it look very, very different?

“If you frame it as an either/or question, it’s too simplistic,” says Utah State University evolutionary biologist Zachariah Gompert. “The answer isn’t ‘completely random’ or ‘completely deterministic and predictable.’ And yet, examining short time scales, we can find predictable, repeatable evolutionary patterns.”

Gompert and colleagues report evidence of repeatable evolution in populations of stick insects in the May 24 online edition of the American Association for the Advancement of Science’s journal Science Advances. Contributing authors on the paper include Gompert’s long-time collaborator Patrik Nosil and other researchers from France’s University of Montpelier, Brazil’s Federal University of São Paulo, the University of Nevada, Reno and Notre Dame University. The research is supported by the National Science Foundation and the European Research Council.

The team examined three decades of data on the frequency of cryptic color-pattern morphs in the stick insect species Timema cristinae in 10 naturally replicate populations in California. T. cristinae is polymorphic in regard to its body color and pattern. Some insects are green, which allows the wingless, plant-feeding insect to blend in with California lilac (Ceanothus spinosus) shrubs. In contrast, green striped morphs disappear against chamise (Adenostoma fasciculatum) shrubs.

Hiding amongst the plants is one of T. christinae’s key defenses as hungry birds, such as scrub-jays, are insatiable predators of the stick insects.|

“Bird predation is a constant driver shaping the insects’ organismal traits, including coloration and striped vs. non-striped,” says Gompert, associate professor in USU’s Department of Biology and the USU Ecology Center. “We observed predictable ‘up-and-down’ fluctuations in stripe frequency in all populations, representing repeatable evolutionary dynamics based on standing genetic variation.”

He says a field experiment demonstrates these fluctuations involved negative frequency-dependent natural selection (NFDS), where cryptic color patterns are more beneficial when rare rather than common. This is likely because birds develop a “search image” for very abundant prey.

“At short time scales, evolution involving existing variations can be quite predictable,” says Gompert, who received a National Science Foundation CAREER grant in 2019 to support his research. “You can count on certain drivers always being there, such as birds feeding on the insects.”

But at longer time scales, evolutionary dynamics become less predictable.

“The populations might experience a chance event, such as a severe drought or a flooding event, that disrupts the status quo and thus the predictable outcomes,” Gompert says.

On long time scales, a new mutation in the species could introduce a rare trait, he says. “That’s about as close to truly random as you can get.”

“Rare things are easily lost by chance, so there’s a strong probability a new mutation could disappear before it gains a stronghold,” he says. “Indeed, another species of Timema stick insect that also feeds on chamise either never had or quickly lost the mutations making the cryptic stripe trait. Thus, the evolution of stripe is not a repeatable outcome of evolution at this long scale.”

Gompert notes replicated, long-term studies from natural populations, including research on the famous Darwin’s finches, are rare.

“Because most of this work is restricted to one or few populations, it is difficult to draw inferences on repeatability among multiple evolutionary independent populations,” he says. “Such studies are challenging to implement not only because they take concerted effort, but also because you can’t rush time.”
Abstract
The extent to which evolution is repeatable remains debated. Here, we study changes over time in the frequency of cryptic color-pattern morphs in 10 replicate long-term field studies of a stick insect, each spanning at least a decade (across 30 years of total data). We find predictable “up-and-down” fluctuations in stripe frequency in all populations, representing repeatable evolutionary dynamics based on standing genetic variation. A field experiment demonstrates that these fluctuations involve negative frequency-dependent natural selection (NFDS). These fluctuations rely on demographic and selective variability that pushes populations away from equilibrium, such that they can reliably move back toward it via NFDS. Last, we show that the origin of new cryptic forms is associated with multiple structural genomic variants such that which mutations arise affects evolution at larger temporal scales. Thus, evolution from existing variation is predictable and repeatable, but mutation adds complexity even for traits evolving deterministically under natural selection.

INTRODUCTION
The extent to which evolution is repeatable and predictable is central to understanding the role of determinism and chance in the history of life, with implications for both basic and applied science (14). These ideas are captured in Gould’s famous metaphor of “replaying the tape of life” (5). Gould argued that historical contingency and chance idiosyncrasies would result in different (i.e., non-repeatable) evolutionary outcomes if the history of life was to be replayed over and over again. However, others such as Morris (6) have argued that evolution is inherently predictable, and many examples of deterministic natural selection promoting repeatable and predictable elements to evolution do exist (3, 7). Thus, beyond spurring decades of debate, Gould’s metaphor has been usefully transformed into an empirical research program (1, 8).

Comparative phylogenetic studies of parallel evolution often support repeated outcomes driven by natural selection (1, 7, 9). However, inferring evolutionary processes and their interplay from such retrospective work can be challenging. For example, selection that fluctuates rapidly between time points can be misconstrued as evolutionary stasis if only end outcomes, or a few distant time points, are analyzed. Detailed studies of the fossil record and ancient DNA can help address these issues (10, 11), as can real-time studies of evolutionary dynamics. The latter are exemplified by studies of experimental evolution in replicated laboratory populations of microbes (1214) and other organisms, such as insects (15, 16). This impressive body of work has revealed not only repeatable patterns of evolution by natural selection but also a role for the contingency of mutation.

In contrast to laboratory experimental evolution studies, replicated, long-term studies from natural populations are rare. Certainly, highly influential long-term studies of the predictability of evolution in the wild do exist, in finches and other birds (1720), moths and butterflies (2123), stickleback and guppy fish (2427), sheep (28), fruit flies (29), and deer (30) (to name a few). For example, rare climatic events affect evolution in the famous Darwin’s finches (19, 20). However, most such work is restricted to one or few populations, making it difficult to draw inferences on repeatability among multiple evolutionarily independent populations (note the distinction between predictability within a population and repeatability among populations, Fig. 1). Thus, replicated studies of evolution in the wild are required to test the generality of the findings from microbes (1214) and to help bridge now disparate laboratory and field studies. Such studies are challenging to implement not only because they take concerted effort but also because time cannot simply be sped up with more effort.

Each line represents a different population, each exhibiting predictable “up-then-down” fluctuations in trait or gene frequency over time. (C) Predictions of less repeatable evolutionary dynamics over time. In contrast to the panel to the left, each population exhibits different patterns of trait or gene frequency change over time. Note the distinction between predictability within any single time series (i.e., population or replicate) and repeatability among them. (D) Empirical variation in morph frequencies in T. cristinae between 1990 and 2023. The orange line (median) and shading [95% equal-tailed probability interval (ETPI)] represent yearly averages on the host plant Adenostoma. The blue line (median) and shading (95% ETPI) represent yearly averages on the host plant Ceanothus. (E) Population-specific morph frequency variation over time, representing replicate evolutionary dynamics (mean number of years per population = 14). Results are shown for the 10 core populations, i.e., replicates, that this study focuses on.
Here, we provide such a study on the basis of compiled data from 30 years of tracking morph frequencies across 10 replicate populations of a stick insect in the wild (Fig. 1). We integrate these data with field experiments, modeling, and genomic data to elucidate the processes driving evolutionary dynamics across timescales. In particular, our genomic analyses allow consideration of the contingency of mutation, which can add complexity and nuance relative to the sole consideration of evolution from standing genetic variation (31). Specifically, mutational dynamics can be related to the genetic architecture of traits, with consequences for the repeatability of evolution at the genetic versus phenotypic level (32, 33). Some predictions are as follows and illustrated in Fig. 2.
Fig. 2. Conceptual diagram illustrating the relationship between the genetic architecture of a trait and the repeatability of evolution at the genetic and phenotypic levels (where the tips of each phylogeny represent a different taxon/species). (A) Hypothetical scenario where a trait (i.e., stripe) depends on a specific mutation. In this case, the evolution of stripe is contingent on the specific mutation occurring and thus occurs only once in the hypothetical evolutionary scenario depicted on the phylogeny. Thus, phenotypic evolution is not repeatable (it would, however, have a repeatable genetic basis if the trait evolved in multiple species). (B) An alternative scenario where stripe depends on a few loci. Here, the evolution of stripe is still contingent on a small number of specific mutations occurring and this might make the trait evolve less repeatedly. Moreover, in such cases, evolution might (or might not) be dependent on the order in which the mutations occur (i.e., some mutations might only be beneficial if another mutation has already occurred). (C) A third alternative scenario where stripe is affected by many mutations (i.e., is polygenic). In this case, stripe does not depend on a specific, unlikely mutation, and is unlikely to depend on the order of mutations. This genetic architecture thus makes the repeated evolution of stripe much more likely, occurring in all four species in the hypothetical example. However, the genetic basis of stripe varies among the species, and, thus, the genetic basis of stripe is not repeatable (different combinations of alleles, i.e., mutations, can generate a stripe). In all diagrams, + and − symbols denote alternative alleles, with + contributing to the stripe phenotype.
When traits are controlled by simple genetic architectures composed of one or few loci of large effect, then individual mutations can strongly affect evolutionary dynamics (4, 34). In such cases, individual mutations “matter” and mutation can be an important consideration for understanding evolution. For example, such architectures offer few mutational targets, making mutations that improve fitness rare (4, 34). Moreover, if there are strong interactions between loci (i.e., epistasis), then only a few genetic combinations may work well together to increase fitness. In other words, there are few mutational sequences or “paths” that adaptive evolution can actually take (4, 3436). Thus, traits controlled by few loci may be challenging to evolve de novo and thus show modest repeatability in their origin over time. However, when such traits do evolve, they will have a predictable, repeated genetic basis (i.e., using the same, few loci and mutations that increase fitness). These predictions could be different for more polygenic architectures composed of many loci with smaller effects (37). Here, no individual mutation has a strong effect on a trait, many loci have redundant effects, and path dependency is unlikely to force a particular mutational sequence to be used to evolve higher fitness. Thus, traits controlled by many loci may evolve repeatedly because they can use a wide range of mutational variation. However, when they do so, a different set of loci and mutations is likely to be used in each instance, making evolution at the genetic level not very repeatable (37).

We acknowledge that there can be much nuance beyond the stylized ideas and predictions noted above [e.g., see (38)]. However, these ideas, nonetheless, illustrate why it can be informative to study the genetic architecture of traits that are being analyzed for their repeatability, particularly to understand the dynamics of evolution from standing variation versus new mutation. In this context, we here combine our time-series and experimental work with genomic analyses of the genetic architecture of cryptic color pattern. Our results reveal clear similarities but also differences with past work focused on body color (rather than pattern, see below for details). Our integrative approach leads to a more complete understanding of the repeatability of evolution than would be possible by studying selection or mutation in isolation.

Ecology and genetics of Timema stick insects
Our study system is Timema stick insects (Fig. 1), a genus of wingless, plant-feeding insects found throughout southwestern North America (39). We focus primarily (but not exclusively) on Timema cristinae, which exhibits three highly heritable morphs and uses two primary host plant species (40, 41). Two of these morphs have diverged in frequency between host species due to strong divergent selection imposed by visual predators such as lizards and birds (42, 43). Specifically, a green unstriped color-pattern morph (green morph hereafter) is cryptic on the broad leaves of Ceanothus. In contrast, the striped color-pattern morph (a green morph that also bears a white, longitudinal stripe on its dorsal surface) is cryptic on the thin needle-like leaves of Adenostoma. Thus, each morph is generally more common on the host on which it is more cryptic, which led to a body of past work on the potential for divergent adaptation between hosts to drive ecological speciation (41, 44). However, we stress that polymorphism is maintained such that both green and striped morphs occur in most populations. This variation is maintained due to negative frequency-dependent selection (NFDS) and gene flow, creating a mosaic of variation in morph frequencies across the landscape, both within and among populations (45, 46). Specifically, the frequency of the striped morph varies within local populations ranging from low (near zero), to intermediate, to high (near one) but is rarely truly fixed (Fig. 1). This provides the requisite variation to study changes in the frequency of green versus striped morphs over time, which we focus on here. There is also a third darkly colored or melanic morph that is rarer and found at comparable frequencies between the two hosts. The melanic morph is not specifically adapted to either host (40, 47) does not fluctuate strongly in frequency over time and does not appear subject to NFDS (40, 45, 47). Thus, we focus first on testing for repeatable fluctuations in color-pattern morphs but return to melanism later in this study when considering longer timescales. We also return to the relationship between polymorphism and speciation at the end of our study.

Past observations and a manipulative field experiment documented changes in color-pattern morph frequencies that were highly predictable due to NFDS (i.e., a fitness advantage to rare forms) (45). This likely occurs due to birds switching search images to hunt for common prey items (4851). Thus, increases in the frequency of the striped morph one year were reliably followed by decreases the following year and vice versa. This past work focused on changes in a single 18-year time series (i.e., a single population or “play of the tape”) because substantial long-term data from other populations did not exist at the time. Thus, past work could not address the issue of repeatability or “replays,” i.e., among replicate populations, per se. We thus focus here on the repeatability of evolution among populations.

We report results from 30 years of data collection on morph frequencies in T. cristinae, representing 692 year-by-host-by-locality estimates of morph frequency derived from 48,349 individuals (Fig. 1 and data S1). Most critically, these data represent 10 localities with at least a decade of the data required to test for NFDS (see table S1; mean, 14 years; maximum, 22 years). These 10 localities were chosen to represent replicates, for example, because of little to no gene flow among them such that each locality undergoes independent yearly changes in morph frequency. Supporting this claim, we emphasize that our 10 localities are geographically separated (fig. S1), generally by several kilometers, yet the average per-generation dispersal distance based on a mark-recapture study is only 12 m (52). This makes it very unlikely that there is sufficient migration between our localities to generate detectable morph frequency fluctuations. Molecular data further support limited gene flow between our localities and thus their evolutionary independence (especially in the context of yearly changes in morph frequency). For example, genetic data have shown that even parapatric populations that are directly adjacent to one another exchange only a few migrants per generation, and all of our study localities here are geographically separated from each other such that gene flow among them is even lower (fig. S1) (53, 54). Thus, each locality acts as a replicate or replay for analyzing the repeatability of evolution, particularly because the distance (i.e., kilometers) typically separating each locality make it likely that different bird and lizard individuals hunt insects at each locality.

Notably, T. cristinae is univoltine with nonoverlapping generations. Thus, each year of data represents a generation, with evolution occurring between each pair of years (the insects diapause as eggs through autumn and winter, hatch in spring, and mate and die in early summer, repeating this cycle each generation). Despite these data representing an appreciable effort, the timescales involved are very different from those associated with Gould’s metaphor. We thus also consider mutations affecting color pattern over deeper evolutionary time (55).

Here, the genetic architecture of color pattern is relevant, for reasons outlined above and in Fig. 2. Specifically, we here evaluate the extent to which stripe depends on specific mutations that could make the repeated evolution of the trait less likely. Past work suggests that pattern is controlled by one or few loci on chromosome 8 (chr8 hereafter) (40, 47, 56). However, the number, effect sizes, and physical distributions of the loci involved remains unclear. Specifically, past work described a region of chr8 named the Mel-Stripe locus that harbors complex structural variation that explains most of the variation in body color (a large inversion and deletion distinguish green versus melanic morphs, indicative of suppressed recombination and opening the potential for linked selection) and is also partially associated with color pattern (striped versus green). However, whether one or multiple regions of Mel-Stripe or even other loci are associated with pattern remains unclear due to (i) the focus of past work on color (not pattern) and (ii) the use of a fragmented reference genome. Here, we integrate better chromosome-level genome assemblies with genome-wide association (GWA) mapping to show that color pattern is actually associated with multiple different structural variants within the Mel-Stripe locus, as well as a chromosomal inversion in a region not associated with color or pattern in past work (i.e., the “Pattern” locus, which is reported here for the first time). We conclude our study by discussing what these genetic details tell us about the repeatability of evolution.

(A) Conceptual overview of known patterns of crypsis. Both T. cristinae and T. podura use Ceanothus and Adenostoma as host plants and both exhibit a green unstriped morph that is cryptic on Ceanothus. In contrast, the two Timema species have evolved different morphs that are cryptic on Adenostoma, the striped morph in T. cristinae (left) and a melanistic gray/brown morph in T. podura (right). (B) Block-specific results of the mark-recapture field experiment testing the fitness of striped versus melanistic morphs of T. cristinae on Adenostoma. Shown is the number of each morph recaptured in each block (i.e., replicate), demonstrating higher recapture and thus fitness of the striped morph. (C) Average fitness of each morph across the entire experiment with the posterior distributions summarized in box plots (boxes denote the median, first and third quartiles of the posterior with whiskers extending to the minimum and maximum or 1.5 times the interquartile range) and individual parameter values sampled from the posterior overlain as points.
In summary, the population of the different morphs changes according to the strength of the selectors in the environment, in a predictable way, at least in the short-term, predictable being in the way the Theory of Evolution by Natural selection predicts. There is no suggestion here that some other, supernatural, force is involved in the process or that the biologists think the TOE is inadequate for explaining the observations. Quite the contrary, in fact, the TOE is confirmed by the observations.

Creationism in Crisis - Observing The Birth Of Galaxies 13.4 Billion Years Before 'Creation Week'


For the first time in the history of astronomy, researchers at the Niels Bohr Institute have witnessed the birth of three of the universe's absolute earliest galaxies, somewhere between 13.3 and 13.4 billion years ago.

Imagine you could look back in time to witness events soon after the Big Bang. How devastating would that be to Ken Ham's strategy of teaching unfortunate children not to enquire how scientists know stuff but to dismiss what they say with the smugly condescending sneer, "Were you there?" as though the only way to know anything is to witness it yourself.

But with the ability to look back in time and actually witness events, and to confirm that those events are exactly as the science predicts based on the normal logical deductions that normal people use - like knowing that your great grandparents had sex, even though no-one witnessed them and they left no record, other than a children born 40 weeks later. According to Ham, there is no way to know that your great grandparents had sex because you weren't there to witness it, so the claim they did has no scientific basis [sic].

So, a child born 40 weeks later could just as well be the result of magic as the result of your great grandparents having sex.

Yep! That's how silly Ham's strategy is and how stupid he has made the willing dupes who use it, sound.

But, to get back to the point of actually looking back in time to witness events 13.4 billion years ago. How is that even possible?

It's possible because of the finite speed of light. When we look deep into space, we aren't seeing events and objects as they are today but as they were when the light reaching our eyes or the detectors on telescopes started out. The further we look into space, the further back in time we are looking, so, when we see objects and events that are 13.4 billion lightyears away, we are seeing them as they were 13.4 billion years ago

And what we see are the first galaxies forming.

So yes, we were there, just as we were there when something happened in the same room. The only difference being the time it took the light to reach our eyes - a few picoseconds or a few billion years. We no less witness an actual event because it took billions of years for information about it to reach us, as we witness an event a few picoseconds ago.

How the scientists at the Cosmic Dawn Center at the University of Copenhagen’s Niels Bohr Institute is explained in a University of Copenhagen Faculty of Science news release, and in a paper published today in Science:
THE UNIVERSE Using the James Webb Space Telescope, University of Copenhagen researchers have become the first to see the formation of three of the earliest galaxies in the universe, more than 13 billion years ago. The sensational discovery contributes important knowledge about the universe and is now published in the prestigious journal Science.

For the first time in the history of astronomy, researchers at the Niels Bohr Institute have witnessed the birth of three of the universe's absolute earliest galaxies, somewhere between 13.3 and 13.4 billion years ago.

The discovery was made using the James Webb Space Telescope, which brought these first 'live observations' of formative galaxies down to us here on Earth.

Through the telescope, researchers were able to see signals from large amounts of gas that accumulate and accrete onto a mini-galaxy in the process of being built. While this is how galaxies are formed according to theories and computer simulations, it had never actually been witnessed.

You could say that these are the first 'direct' images of galaxy formation that we’ve ever seen. Whereas the James Webb has previously shown us early galaxies at later stages of evolution, here we witness their very birth, and thus, the construction of the first star systems in the universe.

HOW THEY DID IT
Researchers were able to measure the formation of the universe’s first galaxies by using sophisticated models of how light from these galaxies was absorbed by the neutral gas located in and around them. This transition is known as the Lyman-alpha transition.

By measuring the light, the researchers were able to distinguish gas from the newly formed galaxies from other gas. These measurements were only possible thanks to the James Webb Space Telescope’s incredibly sensitive infrared spectrograph capabilities.
Galaxies born shortly after the Big Bang
The researchers estimate the birth of the three galaxies to have occurred roughly 400-600 million years after the Big Bang, the explosion that began it all. While that sounds like a long time, it corresponds to galaxies forming during the first three to four percent of the universe's 13.8-billion-year overall lifetime. Shortly after the Big Bang, the universe was an enormous opaque gas of hydrogen atoms – unlike today, where the night sky is speckled with a blanket of well-defined stars.

During the few hundred million years after the Big Bang, the first stars formed, before stars and gas began to coalesce into galaxies. This is the process that we see the beginning of in our observations.

The birth of galaxies took place at a time in the history of the universe known as the Epoch of Reionization, when the energy and light of some of the first galaxies broke through the mists of hydrogen gas. It is precisely these large amounts of hydrogen gas that the researchers captured using the James Webb Space Telescope’s infrared vision. This is the most distant measurement of the cold, neutral hydrogen gas, which is the building block of the stars and galaxies, discovered by scientific researchers to date.
ABOUT THE EARLY UNIVERSE
The universe began its “life” about 13.8 billion years ago in an enormous explosion – the Big Bang. The event gave rise to an abundance of subatomic particles such as quarks and electrons. These particles aggregated to form protons and neutrons, which later coalesced into atomic nuclei. Roughly 380,000 years after the Big Bang, electrons began to orbit atomic nuclei, and the simplest atoms of the universe gradually formed.

The first stars were formed after a few hundred million years. And within the hearts of these stars, the larger and more complex atoms that we have around us were formed.
Later, stars coalesced into galaxies. The oldest galaxies known to us were formed about 3-400 million years after the Big Bang. Our own solar system came into being about 4.6 billion years ago – more than 9 billion years after the Big Bang.
Adds to the understanding of our origins The study was conducted by Kasper Elm Heintz, in close collaboration with, among others, research colleagues Darach Watson, Gabriel Brammer and PhD student Simone Vejlgaard from the Cosmic Dawn Center at the University of Copenhagen’s Niels Bohr Institute – a center whose stated goal is to investigate and understand the dawn of the universe. This latest result brings them much closer to doing just that. The research team has already applied for more observation time with the James Webb Space Telescope, with hopes of expanding upon their new result and learning more about the earliest epoch in the formation of galaxies.

For now, this is about mapping our new observations of galaxies being formed in even greater detail than before. At the same time, we are constantly trying to push the limit of how far out into the universe we can see. So, perhaps we’ll reach even further.

According to the researcher, the new knowledge contributes to answering one of humanity’s most basic questions.

One of the most fundamental questions that we humans have always asked is: 'Where do we come from?'. Here, we piece together a bit more of the answer by shedding light on the moment that some of the universe’s first structures were created. It is a process that we’ll investigate further, until hopefully, we are able to fit even more pieces of the puzzle together

Editor’s summary
Gas in galaxies provides the raw material for star formation. Galaxies in the early Universe are seen to be forming stars rapidly (see the Perspective by Scarlata), but the amount of gas they contain is difficult to determine observationally. Heintz et al. analyzed near-infrared spectroscopy of 12 galaxies at redshifts greater than eight, equivalent to less than 600 million years after the Big Bang. They identified three galaxies with characteristic rest-frame ultraviolet absorption caused by neutral hydrogen gas located in and around the galaxy. The high column densities of gas are sufficient to sustain the rapid star formation occurring in those galaxies, but only for a short period. —Keith T. Smith

Abstract
Primordial neutral atomic gas, mostly composed of hydrogen, is the raw material for star formation in galaxies. However, there are few direct constraints on the amount of neutral atomic hydrogen (HI) in galaxies at early cosmic times. We analyzed James Webb Space Telescope (JWST) near-infrared spectroscopy of distant galaxies, at redshifts ≳8. From a sample of 12 galaxies, we identified three that show strong damped Lyman-α absorption due to HI in their local surroundings. The galaxies are located at spectroscopic redshifts of 8.8, 10.2, and 11.4, corresponding to 400 to 600 million years after the Big Bang. They have HI column densities ≳1022 cm−2, which is an order of magnitude higher than expected for a fully neutral intergalactic medium, and constitute a gas-rich population of young star-forming galaxies.

No wonder frauds like Ken Ham need to be so intellectually dishonest and teach their dupes to be at least as dishonest as they are, when scientists keep producing devastating evidence that the Bible is ludicrously wrong in its description of the creation of a little universe consisting of a small flat planet with a dome over it centred on the Middle East, just a few thousand years ago.

The age of the universe and the forces that produced it are such that the creation of galaxies scientists have now been there and witnessed for the first time, is exactly as science predicted from other strands of evidence than direct observation.

Ten Reasons To Lose Faith: And Why You Are Better Off Without It

This book explains why faith is a fallacy and serves no useful purpose other than providing an excuse for pretending to know things that are unknown. It also explains how losing faith liberates former sufferers from fear, delusion and the control of others, freeing them to see the world in a different light, to recognise the injustices that religions cause and to accept people for who they are, not which group they happened to be born in. A society based on atheist, Humanist principles would be a less divided, more inclusive, more peaceful society and one more appreciative of the one opportunity that life gives us to enjoy and wonder at the world we live in.

Creationism in Crisis - How Dinosaurs Evolved Feathers


Latest News and Views from University College Cork

Psittacorus (reconstruction)
Artwork by Walter Myers
This paper is enough to send a dedicated creationist disinformation specialist into intellectual summersaults. On the one hand, they hate the fact that dinosaurs lived so long ago and are evidence of life on earth tens and hundreds of millions of years ago, so they bend over backwards to prove they were around just a few thousand years ago, and then, horror of horrors, along come some clever scientists and show evidence that some dinosaurs even evolved into birds!

And now, courtesy of Palaeontologists at University College Cork (UCC) in Ireland , we have evidence of the transition from scales to feathers in pre-avian dinosaurs.


But it gets even worse! Creationists frauds have ben claiming for several years now that 'fossilised' soft dinosaur tissues prove they were just a few thousand years old because, despite the perfectly rational explanation of how 'soft' tissues can be preserved for many millions of years in the right circumstances, like the presence of iron, the evidence of this transition from scales to feathers would found in fossilised soft tissue!

So, a creationist disinformation specialist must now argue that fossilised dinosaur soft tissues don't exist, and when they do, they prove dinosaurs lived recently. One problem they face is that the fossilised skin isn't skin at all, or even the fibrous protein parts of skin; it has been entirely mineralised aa silicate, preserving only the morphology, including the surface patterning - which is where the evidence lies.

The University College Cork scientists have just published their findings, open access, in Nature Communications and in a UCC news release:

Creationism in Crisis - Common Origins of Horns, Antlers and Ossicone In Hooved Mammals

Although the horns of cattle, gazelles and goats look very different to the antlers of deer and the ossicones on the head of a giraffe, and indeed, they are constructed differently, the cells they develop from in the embryo are the cells of the 'neural crest' that also develop into the face rather than the rest of the cranium. That and the fact that the underlying genetic control of their growth is sufficiently similar, provides compelling evidence that they share a common origin from which they, and the orders of which they are typical, have diverged.

This is the conclusion of two researchers at the American Museum of Natural History and Baruch College and the CUNY Graduate Center, who have just published their findings, open access in the journal, Communications Biology. It is also explained in an American Museum of Natural History press release:
