Prehistoric teeth fossils dating back 9.7 million years 'could rewrite human history' | The Independent

According to press reports, yet another re-write of human evolutionary history is due because a couple of 9.7 million year-old fossil teeth found in Germany look somewhat like those of "Lucy" (Australopithecus afarensis) from Ethiopia, Africa.

But things are maybe not what the headlines claim. Journalists have a vested interest in sensational headlines, even more so when the page carries adverts which are interspersed in the article itself and grab your attention. Also with a vested interest in sensational headlines, are those who supply the soundbites journalists yearn after.

Caring, Compassionate Neanderthals

External auditory exostoses and hearing loss in the Shanidar 1 Neandertal

Here we have lovely evidence that altruism and compassion are not uniquely modern human characteristics, as creationists would have us believe.

A 50,000 year-old Neanderthal, unearthed in 1957 during excavations at Shanidar Cave in Iraqi Kurdistan and know to science has Shanidar 1, shows evidence of old injuries and medical conditions that would have made independent existence in the Pleistocene impossible.

A new examination of the skeleton by Erik Trinkaus of Washington University in St. Louis and Sébastien Villotte of the French National Centre for Scientific Research, shows that the male in his 40s (believed to be elderly for a Neanderthal) must have received considerable support and care following his injuries which would have made hunting and foraging difficult or impossible. He is unlikely to have avoided falling prey to the many predators in the Pleistocene.

Irish Catholicism is Dying

Irish Catholicism is dying | IrishCentral.com

The news for the Irish Catholic Church just got a lot worse.

The 2016 census shows a further dramatic decline in support for the Catholic Church. Most other Christian denominations saw a similar fall but, given its position as by far the largest of them, as the table on the right shows, the fall was especially acute for for Catholicism.

The table needs to be read carefully. For example, the decline of 'only' 3.4% since 2011 for Catholics represents a fall of 132,200 but an increase of 28.9% for Muslims represents an increase just 14,200.

These changes are despite an annual population growth rate averaging 0.84% over the five years to 2016.

According to the Centre For Investigative Reporting (Reveal), the Jehovah's Witness parent organisation, The Watchtower Bible and Tract Society, is facing a $66 million law suit in Canada, brought by current and former members, claiming that it's policies protect members who sexually abuse children.

Lessons From a Canary Island - Spells and Incantations

Fan vaulting in the Cathedral of Santa Ana,
Las Palmas, Gran Canaria, Spain

Cathedral of Santa Ana, Las Palmas, Gran Canaria, Spain

Sitting at the end of a rather plain but pleasantly peaceful, palm-tree-lined plaza, is the Catholic Cathedral of Santa Ana, the most important religious building in the Canary Islands. It is situated in the old town area, now the southern suburbs of Vagueta in the modern city of Las Palmas, Gran Canaria, Spain.

By the standards of most European Catholic cathedrals, the Cathedral of Santa Ana, is outwardly plain, even a little austere, although it is blessed with two campaniles.

The original cathedral was built between 1500 and 1570, commencing soon after the Spanish conquest of the Canary Islands by the armies of Ferdinand and Isabella, flushed with their success at the conquest of the entire mainland Spain and the expulsion of the Moors from their last remaining stronghold in Grenada. At the time, the Canaries were inhabited by a people known as Guanaches who almost certainly originated in the Atlas Mountain area of Morocco and migrated there in pre-classical times.

Conquest had not been easy, being vigorously resited by the native Guanaches who had also resisted earlier attempts at colonisation by a Castilian force led by the Frenchman Jean de Béthencourt who was proclaimed King of the Canaries when he managed to capture Fuerteventura in 1405. A descendant of Jean de Béthencourt, Maciot de Béthencourt sold Lanzarote to Portugal in 1448. This upset both the Castilians and the Guanaches and despite Pope Nicholas V ruling that the Canaries were a Portuguese possession, the Portuguese were expelled by a popular revolt in 1479. Eventually, the Canaries were ceded to Spain by treaty with Portugal but the conquest was not completed until 1497.

Evolving Great Tits - In Our Back Gardens

Evolution in your back garden—great tits may be adapting their beaks to birdfeeders.

Great tits are evolving, just up the road from where I live!

Not ten minutes drive from where I sit writing this blog-post is probably the most intensely studied piece of woodland in the world, and probably nowhere is studied by people more qualified to study it. Wytham Woods is a mixed woodland owned by Oxford University and widely used for field studies by biologists from the Zoology Department.

It was by comparing the great tits from here and from Oosterhout and Veluwe, in the Netherlands, that an international research team discovered that the UK great tits have been actively evolving over the last few decades and now have longer beaks than their Dutch counterparts.

The conclusion was that it was probably the British tradition of feeding birds with peanuts in feeders designed to be inaccessible to all but the smaller birds such as tits. This may have provided the selection pressure for longer beaks to become the fitter beaks in the environment of British gardens. The British spend about twice as much on bird feeders and the food to put in them as other Europeans. Early in the 20^th Century the satirical magazine Punch described bird-feeding as a British national pastime.

Lessons From A Canary Island - Rock of Ages

The core of an old volcano, Gran Canaria

The great thing about going to somewhere different is that you see different things - if you look.

We've just got back from a little over a week in the Spanish Canary Island, Gran Canaria, just off the coast of West Africa. Yes, it's where the Canary finch comes from but, apart from a brief glimpse that might have been one and a couple in a cage, we never saw any. In fact, we saw very few birds. A few buzzards, a couple of kestrels, some egrets and herons and quite a lot of gulls, but nothing to get excited about and no new species to cross off my list!

This is mostly because Gran Ganaria is hot and arid and, being volcanic, has very little soil for anything much other than cacti and other succulents to grow in. There are pine woods on the higher places but still not a lot of wild life.

And this means that a great deal of the underlying geology is, well, not really underlying so much as overlying and exposed. It's black volcanic tuffa, pumice, basalt and towering columns of extinct volcanic core with the core eroded to expose the solidified magma as in the photograph on the right.

This, of course, if only they would look at it, is a problem for creationists because there is no way to explain the geology of Gran Canaria in terms of the product of a recent global flood or of volcanic activity in just a few thousand years since one. It is, quite simply, as close as science comes to proof that there never was a recent global flood and the Earth is actually very old. Although, on the accepted scientific understanding of the age of Earth, the Canary Islands are comparatively young - i.e., just a few tens of millions of years old.

Just a Small Problem - For Creationists

Lars Gibbon
The last common ancestor of the hominoids may have been about this size.

Research Sizes Up Last Common Ancestor of Humans and Apes:

You know that intermediate form between the old world monkeys and the primates, including humans, that creationists insist never existed?

It weighed about 12 pounds (5.5 Kg) according to a pair of researchers based at the American Museum of Natural History.

As the American Museum of Natural history press release explained:

So What's So Special About Humans?

Whales and dolphins have rich ‘human-like’ cultures and societies

Another creationist claim has been falsified (not for the first time, obviously) but this time fairly comprehensively.

The claim is that for a list of reasons, humans are a special creation, endowed with special qualities and abilities, that separate us from the other animals, justifying the claim that the purpose of 'creation' was to create mankind, and all the rest is just there for our use.

It's not good enough that were are unique, just like any species is unique, hence being a distinct species. Humans have extra-special characteristics that makes us uniquely, unique, apparently.

Getting To Know Your Inner Neanderthal

The Contribution of Neanderthals to Phenotypic Variation in Modern Humans: The American Journal of Human Genetics.

We've know for some years now that modern non-African humans have some Neanderthal DNA. This must have been acquired by interbreeding during the comparatively brief period between the migration of anatomically modern humans (AMHs) out of Africa about 50-60,000 years ago and 40,000 years ago when Neanderthals went extinct.

We also know that this interbreeding was not entirely successful and probably didn't always produce viable offspring. For example, there are no known examples of either Neanderthal Y chromosomes in modern

Today we have a lovely example of how the Theory of Evolution forms the foundation of biology, enabling biologists to make predictions and make sense of what we can see today in the diversity and similarities of organisms; in this case, plants.

Contrary to what creationist frauds would have their willing dupes believe, not only is there no sign that the Theory of Evolution is a 'theory in crisis' but there is every sign that it is never even seriously doubted. No-one tries to validate it these days; it is simply accepted as the very basis of biology as surely as atomic theory is the basis of chemistry.

Fossil points to early rise of ancient crocodiles | The University of Edinburgh

In a vindication of the way science constantly re-examines and re-assesses itself in the light of new information, some of the most rewarding fossil hunting is now being done in museums.

The museums of the world contain millions of fossils, very often meticulously catalogued with details of when and where they were discovered, but filed away in draws and cupboards and almost as effectively hidden from general view, and often scientific view, as they originally were when buried in rocks awaiting discovery by some intrepid fossil hunter a century or more ago. At the time of their discovery they may well have been mere curiosities. With little information to go on, no-one would have been aware of their significance or where they fitted in the evolutionary history of life on Earth.

The jigsaw puzzle was then far too fragmentary to know where this particular piece fitted.

One such fossil was recently discovered in the archives of the Natural History Museum, London, where it had been since 1875. It had originally been discovered about 150 years ago at Melksham, Wiltshire, England, in a formation known as Oxford Clay. When examined in detail by a team from Edinburgh University, Scotland and the Natural History Museum, London, it was found to be that of the earliest known crocodylomorph of the Geosaurini lineage, putting the evolutionary origins of this group back millions of years before the 152-157 million years previously thought.

Was This The Hominin That Gave Us Genital Herpes?

Paranthropus boisei
The species responsible for human genital herpes?

Meet the hominin species that gave us genital herpes | University of Cambridge

One of the best pieces of evidence for common descent is the way the genetic relationships between our obligatory parasites and those of their related species, almost exactly maps onto the relationship between our genome and those of our own relatives. I have previously written about how the evolution of our lice can be mapped onto our own evolution and divergence from the other apes.

Another parasite which, if anything, is even more obligatory that lice is the herpes virus, and like our lice there is not a close but not perfect match with our evolution. All primates are host to two versions of the herpes simplex virus, HSV1 which in humans causes cold sores and HSV2 which causes genital herpes in humans. The latter is normally regarded as a sexually transmitted disease.

Whereas we can make a direct link between two of our lice - the head louse (Pediculus humanus capitis) and the body louse (Pediculus humanus humanus) - and the body lice of chimpanzees (Pediculus schaeffi), there is no such clear link with the pubic louse and an immediate ancestor. We can see how our body louse became our head louse when we lost our body hair and it had nowhere else to go and how it then diverged into two subspecies when we started wearing clothes to become our body louse as well. However, the closest relative of our pubic louse (Phthirus pubis) is the gorilla body louse (Phthirus gorillae)! Somewhere in our evolution, the gorilla louse jumped the species barrier, otherwise it, or as descendent, would be present on chimpanzees too. The degree of divergence is enough to show that this wasn't a recent event, but somewhere, after we diverged from the chimpanzees, one of our ancestors got close enough to a gorilla to catch pubic lice from it!

Swing A Chicken For Your Sins

Six Israeli activists wounded in protest against Yom Kippur chicken-swinging ritual | Jewish Telegraphic Agency

Ever since the Abrahamic religions invented the idea of sin, they've had to be even more inventive to provide cures for it.

For a Muslim, it's strict adherence to the rules, daily prayers, pilgrimage to Mecca and giving to charity. For a Catholic, it's confession, rituals and magic words as prescribed by the priest. For a Protestant, it's accepting Jesus and giving money to the church.

And for some ultra-conservative Jews, it's swinging a live chicken round your head the day before Yom Kippur (the Day of Atonement). The chicken is then killed and the meat given to charity.

Child Porn Priest Rescued by Vatican

Just about everyone must now be aware of Pope Frankie's loudly proclaimed determination to reform the Catholic Church and put a stop to the multiple child abuse scandals that were costing it money and members. No longer are these habitual abuses, routine cover-ups and tacit approval of them to be tolerated, so the way the church dealt with the latest child abuse scandal should come as no surprise.

When the Vatican heard that yet another Catholic priest was under investigation by the Canadian Police for child pornography offences, it lost no time in dealing with the matter in the interests of all concerned.

Modern humans may have been around for nearly twice as long - Uppsala University, Sweden

More evidence today of modern humans emerging gradually from archaic hominins in Africa.

This genetic and archaeological analysis by a team from Uppsala University, Sweden, and the University of Johannesburg, South Africa, suggests, contrary to accepted wisdom, that modern humans may have diversified from archaic forms significantly earlier than generally believed and maybe not in a single location from a single founder species.

The suggestion is that anatomically modern humans could have gradually diversified in different African regions, then gene flow between the emerging groups produced the single, genetically diverse, species we now recognise as Homo sapiens.

This new study has been made possible by improved DNA extraction techniques which are revolutionising archaeology and evolutionary biology.

To read the headlines, you might be tempted to believe a miracle has been prove true by scientists.

What's been proven, if anything, is just how little evidence is needed before the promoters of religious superstitions start to proclaim proof.

The mythical miracle this time is one I confess I had never heard of and about which the details, as with all the best of miracles, is sadly in very short supply. It is the 'miracle' of St Francis of Assisi's bread which, in 1224, so the story goes, a sack-full of which appeared on the doorstep of the Franciscan Friary of Folloni in southern Italy, so saving the brothers within from starvation, the friary being cut off by snow.

Declining Christianity in USA

America’s Changing Religious Identity:

A major new report published today by PRRI has revealed a continuing decline in religious affiliation with 'nones' now comprising 24% of the population.

There is now a marked generational shift in religious affiliation with 38% of the key 18-29 year-old age group identifying as 'nones' against just 12% for the 65+ age group. White Christians now comprise just 24% of the 18-29 year-olds against 63% of the 65+ age group.

The report also reveals the continuing decline in White Christians who fall below 50% for the first time in a PRRI survey, although other surveys have also reported a similar recent finding. This group, which in 1976 comprised 81% of all American adults, now accounts for just 43%.

Two other significant findings were the increasing ethnic transformation of American Catholicism which, 25 years ago was 87% White, compared to 55% today, and the increasing polarisation of American politics on religious grounds. 73% of Republicans are White Christians compared to just 29% of Democrats. A decade ago, 50% of Democrats were White Christian.

Religious Belief in UK Continues to Plummet!

British Social Attitudes: Record number of Brits with no religion.

The catastrophic (from the point of view of those who earn their living from it) decline in religious belief in the UK continues apace according to the authoritative British Social Attitudes Survey. 'No religion' has rockets by 5% in just one years, from 48% in 2015 to 53% in the latest (2016) survey.

More than half (53%) of the British public now describe themselves as having “no religion”, up from 48% in 2015. The proportion of non-believers has increased gradually since the survey began in 1983, when the proportion saying they had no religion stood at 31%.

Church of England decline continues
The decline in religious affiliation is hitting the Church of England particularly hard. Just 15% of people in Britain consider themselves Anglican, half the proportion who said this in 2000.

The proportion of non-believers has risen from just 31% in 1983 when the survey began.

One again the church of England has seen the biggest decline and has now fallen to 15%; half what it was in the year 2000. By contrast, the proportion of self-identified Catholics has remained stable at around 5%. Other religions account for a further 6%.

The fall in religious affiliation has been driven mostly by a decline in the proportion of 18-24 year-olds identifying with a religion, but there was a decline in all age groups between 2015 and 2016. 'No religion' in the 18-24 year-old age group increased to 71% from 63% in 2015; a stunning 8% rise in a year! In this group, Anglicans now comprise just 3%.

New study contradicts assumption that true frogs diversified as they expanded their range around globe | The University of Kansas

One of the nice things about science is that, properly done, it can throw up some surprises, even overthrowing some preconceptions and axioms.

Science demands we constantly question and reassess our assumptions and preconceptions. It is not for those who prefer simple certainties over difficult truths.

For example, it is generally assumed that when a species colonises new geographic regions with new ecological niches, it will tend to adapt and radiate into several new species; that range extension itself is a major driver of speciation.

But this is not always so, it seems.

It's just another of those pieces of information that creationists have to avoid, of course, but the people of Papua New Guinea have been isolated from the rest of the world for 50,000, and people in some mountain valleys have been isolated from their neighbours for 10-20,000 years!

So, if you subscribe to the Young Earth Creationist superstition, these people are much older than Earth, have been isolated since before Adam and Eve, and appear to have avoided the Biblical flood entirely.

Yes! It is a silly superstition, isn't it, yet some apparently otherwise normal adults believe it!

Anyway, back to reality.

Just Another Child Abuse Scandal.

Smyllum Park, Lanarkshire, as it appears today.

Hundreds of Scottish orphanage children allegedly buried in mass grave | UK news | The Guardian

Normally, when people talk about systematic, institutionalised child abuse, we think of priests and male teachers abusing vulnerable children in their care or over whom they have trusted authority. It speaks of the sheer volume of these cases that yet another exposure barely rate a mention in the news any more. It's as though we have come to expect men of the cloth to abuse their power for their own gratification.

But, despite the documented abuses in Ireland and Spain where it was nuns, sometimes with the connivance of priests, who were doing the abusing, it still comes as something of a shock when we hear of female clerics abusing children. Somehow it seems even sicker when a supposedly maternal female is looking at children as a source of amusement and sexual or sadistic gratification, yet these cases seem to have been no less prevalent in institutions where nuns were in similar positions of power over children as are the abusive priests.

Today, we have another shocking example.

Six Million Year-Old Cretan Footprint Problem - For Creationism!

Six Million-Year-Old Human Footprint Discovered in Crete Raises Major Questions About Our Evolution

A neat illustration this week of how the popular media distort and misrepresent science in order to appeal to a wider audience and in doing so, feed and reinforce popular misconceptions.

First, we have MSN news announcing that six million year-old human footprints have been found in Crete. This then, of course, is presented as raising 'major questions' about our evolution. Creationists groups on Facebook and elsewhere are already full of claims that this proves science has got everything about evolution all wrong, either neglecting the six million years of explaining them away as proving science even gets the dating wrong.

The source of this story was the press release from Upsala University, Sweden, which announced the publication of a paper by a team based there. Unlike the MSN headline - "Fossil footprints challenge established theories of human evolution" - the headline on this press release was more muted (and of course more accurate). No mention of human footprints there, although there was an attempt to associate the discovery with current understanding of human evolution.

But what understanding was challenged, exactly?

He plea-bargained this down to one admitted case of disseminating child pornography in return for the other 39 charges being dismissed.

Antarctic mystery microbe could tell us where viruses came from | New Scientist

A recent discovery in Antarctica could shed some light on the origin of viruses.

Ricardo Cavicchioli of the University of New South Wales in Australia and his colleagues found a microorganism, an archaean, Halorubrum lacusprofundi R1S1, in lakes on the Rauer Islands, Antarctica. That's not unusual in itself; new organisms are discovered daily. What was slightly unusual with this particular one is that it contains an independent plasmid that the team have names "pR1SE". Plasmids are small fragments of DNA, often circular, that are self-replicating and often carry a gene that is beneficial to the organism. Bacterial antibiotic resistance is often carried on a plasmid and, as such, can be transferred to other bacteria.

It must be difficult being a dedicated creationist. You need to believe so many diametrically opposed views simultaneously.

They need to hold to the view that this bacterium was intelligently designed to circumvent the human immune system (that the same designer had designed to protect us and then had apparently regarded that as a problem to be solved!) and to the view that something capable of this degree of mendacious malevolence is an omni-benevolent, maximally good god.

Tiger Snakes Won the Venom Wars

Australian Eastern tiger snake

Source: Wikipedia

Why tiger snakes are on a winner - UQ News - The University of Queensland, Australia.

Venomous snakes make interesting subjects for study in that they represent an example of a complex evolutionary arms race which can be traced in their venom. This is often a complex mixture of related but subtly different chemicals, often coded for by genes which are themselves subtly different versions of one another.

The arms race is due to snakes usually preying on a range of prey species, each of which has selection pressure to evolve resistance to the snakes venom. But, if the snake merely responded to one prey's resistance by changing it's venom, this might be less effective against another of its prey species, so there is evolutionary pressure on the snake to retain it's 'older' venom but supplement it with a newer version as well. This occurs by gene duplication, then mutation of the 'spare' copy.

Seriously Christians? Really?!

There are actually adults who believe the sun can stand still and performs strange manoeuvres in the sky!

Not just that but they believe these could be visible only in a small village or town, and non-one else on Earth would see them!

Seriously! There are actual grown ups who believe the following:

Then spake Joshua to the LORD in the day when the LORD delivered up the Amorites before the children of Israel, and he said in the sight of Israel, Sun, stand thou still upon Gibeon; and thou, Moon, in the valley of Ajalon. And the sun stood still, and the moon stayed, until the people had avenged themselves upon their enemies. Is not this written in the book of Jasher? So the sun stood still in the midst of heaven, and hasted not to go down about a whole day. And there was no day like that before it or after it, that the LORD hearkened unto the voice of a man: for the Lord fought for Israel. And Joshua returned, and all Israel with him, unto the camp to Gilgal. But these five kings fled, and hid themselves in a cave at Makkedah.

Retracing the First Americans' Footsteps

Postglacial viability and colonization in North America’s ice-free corridor | Nature

One of the enduring mysteries of the story of the human migration into North America is the exact route taken and the timing of the migration(s). There is now no real doubt that North America was populated first with a subsequent rapid spread into Central and South America, and that the people came from Siberia via the Beringia; the land bridge between Siberia and Alaska, the remnants of which are the Aleutian Islands.

Looking south through what was once the “ice-free corridor” in present-day Canada. A new study suggests that humans couldn’t have traversed through the corridor until about 12,600 years ago - too late to have been the route taken by the first inhabitants of North America.

I won't call creationism a theory in crisis because that would be giving it a scientific standing far about what it deserves. It's a notion; a guess with no supporting evidence; an idea with no practical application other than making a few deeply ignorant people feel important enough.

A point I've made several time recently, but which I'll repeat again for those who may have missed it, science, especially biological, geological, archaeological and cosmological science, daily and routinely refutes creationism without the slightest effort or intent simply by reporting the facts.

Just Another of Those Mythical 'Missing Links'

The Leakey Foundation | New 13 million-year-old infant skull sheds light on ape ancestry

It's another bad week for creationism. Is there ever a good week?

Close on the report of the earliest known primate fossil we now have the remarkably complete skull of an infant who lived 13 million years ago in what is now Kenya, and which is close to the common ancestor of the hominids and the other African apes. It gives us a fairly good idea of what the last common ancestor would have looked like.

The skull was found by fossil hunter John Ekusi in 13 million year-old rock layers in the Napudet area, west of Lake Turkana in northern Kenya; a formation that is easy to date reliably because of the activity of a nearby volcano. The skull, along with forest trees, was buried by volcanic ash, showing that they were buried during the same catastrophic event.

Evolution! Now a Theory With Teeth!

Amateur collectors in Japan discover country's first and oldest fossil diving bird -- ScienceDaily

As a keen fossil hunter in my early days, I dreamed of finding something more than the usual marine shells - the muscles, oysters, bivalves and marine snails that are common in North Oxfordshire limestone deposits - so I can imagine how two Japanese fossil-hunting brothers, Masatoshi and Yasuji Kera, on the island of Hokkaido must have felt when they found nine skeletal elements of what turned out to be the oldest early Asian diving bird.

Fossils of these birds are relatively common in the Northern Hemisphere, but this is the first to be found in Asia and the first from the easterm margin of the Eurasian continent.

I'm thinking of starting another blog called Filling The Gaps. There are just too many examples of these 'missing' fossils to include in this one without it coming to resemble a blog devoted to nothing else.

These examples of things creationists insist are missing being found and described by science are almost a daily occurrence from the field of biology alone. If science was bothered about creationism and scientists felt they still needed to prove evolution and disprove creationism there would probably be several scientific journals called something like the Journal of Creation Falsification or Journal of Evolution, but of course it isn't needed because science has no such need.

There is a reason creationism is absolutely obsessed with falsifying and misrepresenting science and presenting science as some sort of vast conspiracy theory or based on false assumptions and therefore invalid - unless it can be made to appears to support creationism, then it's conclusive and irrefutable, of course.
