What can zebrafish teach us about our survival in the face of mutations? | Carnegie Institution for Science
What would you do if you were an intelligent, omniscient, omnipotent designer and found that your perfect design kept going wrong in unexpected and unpredictable ways?
Well, if you were a creationist intelligent designer it seems, you would still regard yourself as an omniscience, omnipotent, perfect designer but you would wouldn't improve your design so it didn't keep going randomly wrong - because it's already perfect! Instead, you would set about designing a clunky workaround that went some way towards rectifying those omniscient mistakes and you would settle for near enough is good enough - apparently.
This is (leaving out the intelligent designer nonsense) what researchers Steven Farber, Jennifer Anderson and colleagues, of the Carnegie Institution have show happens in the zebrafish to cope with detrimental mutations. Rather than putting up with mutations resulting in individuals failing and being removed from the population gene pool, zebrafish, and maybe lots of other species, have evolved mechanisms for coping with them by either neutralising them or at least minimising their detrimental effects.

Another Faith-Based Massacre
The al-Rawda Sufi mosque, Bir al-Abed, Sinai, Egypt Photo credit: EAP |
Islamic jihadists believed to be affiliated to Islamic State (IS) have attacked a Sufi mosque in Sinai, killing at least 300 people, now revised upwards from the BBC News report.
The reason? Because the Islamic tradition of Sufism is considered heretical by fundamentalist Sunni Muslims, so obviously those who believe they know the mind of Allah believe Allah wants heretics killed and needs their help to kill them.

Malaria - Good News for Creationists as Trump Helps God!
World-wide incidence of malaria (Note: the USA is mamaria-free) |
At last something for creationists of the ID persuasion to celebrate!
Remember, creationists believe that their intelligent (sic) designer is the god they claim is the maximally good giver of morals who always acts to maximise the good in a world which runs perfectly according to his omni-benevolent, omnipotent and omniscient plan.

The Brutal Despot and the Catholic Priest
Robert Mugabe. "God has saved his life" - Fr. Mukonori Photo credit: AP |
As we say goodbye to the tyrannical psychopath who has run Zimbabwe for the last 30 years and the Zimbabwean people celebrate, let's look at the role of the Catholic Church and in particular the Catholic priest who was his confidante and most loyal supporter - Fr. Fidelis Mukonori.
Fr. Mukonori is a Jesuit priest and has been a friend of Robert Mugabe since before he came to power. During the independence struggle as ZANU-PF led by Mugabe and ZAPU led by Joshua Nkomo waged a guerilla war against the illegal white supremacist government under Ian Smith, Fr. Mukonori travelled around Zimbabwe - then called Rhodesia - under the cover of the Catholic Commission for Justice and Peace in Rhodesia, gathering information about the progress of the liberation struggle and passing it on to Mugabe.

Another Victory for Humanism Over Faith-Based Barbarity
Ratko Mladić, mass murdering war criminal |
Ratko Mladić, devout Orthodox Christian, the Butcher of Bosnia, has been found guilty by the UN war crimes tribunal in The Hague of crime against humanity for his part in the Bosnian Genocide in the early 1990's.
He has been on trial since 2012 since when he has been held at the Scheveningen prison in The Hague where he spends his days playing chess against his compatriot, coreligionist and fellow genocidist, Radovan Karadžić, former president of Serbia, who was convicted of genocide in 2016. The third member of the murderous regime that took over Serbia following the break up of Yugoslavia, Slobodan Milošević, escaped conviction by dying during his trial.
Mladić, aged 74, has been sentenced to life imprisonment.
The crimes were committed in the series of wars which followed the break-up of former Yugoslavia when Orthodox Christian Serbia tried to exert control over neighbouring Bosnia and Croatia to create a 'Greater Serbia', maintaining the traditional Serbian domination of Yugoslavian politics.

Christians and Jews Unite to Defend Paedophilia
Rabbi Noson Shmuel Leiter, director of Help Rescue Our Children Speaking in Birminham, ALabama in support of Roy Moore |
Following close on American Christian fundamentalists discovering that their religion permits lying, sexually assaulting women, adultery, cheating, fraud and bullying when they discovered that Donald Trump represented all the values they stand for, they now seem to have realised what good and moral things paedophilia, sexual assault on and non-consensual sex with a minor are, with the Roy Moore affair.
Now we learn it's not just extremist Christians who have these conveniently flexible morals and an imaginary friend who approves of every abuse of power and antisocial, divisive and abusive policy you can think of when it suits your selfish ambitions. Some extremist Jews have the same flexibility it seems.
Evangelical Christian preachers seem to be vying for the best Bible-based apologia for Moor's alleged sexual abuse of young women including a fourteen year-old girl some years ago. It not only does not debar him from holding elected public office, but is makes him eminently suitable as a good Christian - apparently. They have just discovered that the Bible is full of child molestation and non-consensual sex (or 'rape' as we now call it) all done with the tacit approval of God or even on his orders. Why, even Jesus's own mother was a minor!

Evolving Creationists!
Old Order Amish, evolving - naturally |
Shocking news for creationists yesterday!
Fundamentalist Christian creationists have been caught evolving and breaking one of the sacred creationist dogmas - that all mutations are harmful and degenerative. This was discovered in a group of appropriately-named Old Order Amish from Indiana, USA.
Due to a mutation, they are living 10% longer compared to those members of the same Amish group without the mutation.

Two 'World Views'
Campylobacter jejuni
Image Credit: Kateryna Kon / Shutterstock
Kingston University study reveals how food poisoning bacteria Campylobacter uses other organisms as Trojan horse to infect new hosts - News - Kingston University London
I heartily dislike the term world view. It's nothing more than an attempt to pretend that an opinion which isn't supported by the evidence is the equal of one that is. And that's a very convenient way to justify demanding the right to be taken seriously on any subject without bothering to learn anything about it.
A 'world view' that either eschews scientific evidence or actively rejects it is not an opinion based on an interpretation of the data; it's an opinion that ignores it.
But let's play this 'different world view' game that creationists play where they pretend they have looked at all the evidence and simply arrived at a different conclusion based on their 'world view' not the scientific 'world view' - which, so they would claim, is no more valid than their own!

A Victory for Human Decency in Australia
Australians celebrate victory over religious bigotry |
Great news from Australia!
In a non-binding 'advisory' postal vote, Australians have voted 61.6% in favour of legalising same-sex marriages on a 79.5% turnout. Unlike normal Australian voting where voting is compulsory, this referendum was voluntary, which makes this turnout even more remarkable.
On a regional basis, only 17 of the 150 electorates voted against the proposal "Should the marriage law be changed to allow same-sex couples to marry?" Australia's chief statistician, David Kalisch said, "This [turnout] is outstanding for a voluntary survey and well above other voluntary surveys conducted around the world. It shows how important this issue is to many Australians".

Be Upstanding For Jesus
Pasto Paseka 'Mboro' Motsoeneng of the Incredible Happenings Ministry.
Katlehong, South Africa
Pastor demands footage of him reviving parishioner's erection be shown on TV | Metro News
A South African pastor is proclaiming a miraculous cure for impotence and demanding it be shown on Soweto television.
Pastor Paseka ‘Prophet Mboro’ Motsoeneng, of the Incredible Happenings Ministry in Katlehong, South Africa, will already be familiar to readers of this blog for his amazing powers (and amazing wealth). Only last July, on God's instructions, he went into Hell and killed Satan according to his announcement on his Facebook page (that was mysteriously taken down soon after it appeared - which had nothing to do with a very large number of complaints, obviously).
We can be sure this is true because Prophet Mboro is a Christian and it is forbidden for Christians to bear false witness, i.e., lie!

Religion Is Not Natural
[left caption]
[Right caption/credit]
Why do we believe in gods? Religious belief not linked to intuition or rational thinking, new research suggests
Are people born with the propensity to be religious, as some studies seem to have shown?
It is even claimed in some religious apologetic circles that somehow being religious is the natural state, either an evolved genetic predisposition, or, in fundamentalist creationist apologetics, that God intelligently designed us to be religious (obviously it couldn't have evolved, that would be heretical!).
Strangely, this god intelligently designed us to be religious but couldn't make us all have the 'one true religion'.
Of course, the bottom line is that somehow, atheism is unnatural, even perverse and definitely not something God intended.
The basis for that view of the origin of religiosity is based on the idea that religious belief is based on intuition rather than rational, analytical thinking (the Intuitive Belief Hypothesis). Certainly, arguments for creationism are invariable intuitive or more accurately, incredulitive, "I don't understand it, or can't believe it, therefore God!"
Now a new study by academics from Coventry and Oxford universities casts considerable doubt on this view and suggests that intuitive vs analytical thinking actually don't have much bearing on religious belief.

'Missing Link' in Abiogenesis Found!
Scientists find potential 'missing link' in chemistry that led to life on Earth
You know, sometimes I get carried away and fantasise about creationist frauds like Ham, Comfort and Hovind hearing the tune Aproaching Menace by Neil Richardson as they read yet another scientific paper showing how science is closing in on one of their sacred dogmas - that only God can create life.
But then I come back to reality and remember that they don't do science and evidence, so none of this makes any difference to them. They'll still claim it's impossible, knowing they can rely on their willing dupes not to check just in case.
Only three days ago I reported here on the work of a team from the Georgia Institute of Technology, Atlanta, GA, USA who are homing in on one of the pre-biotic precursors of one of the fundamental cell processes. Just a day later we had this paper published in Nature Chemistry showing how another fundamental process could similarly have arisen pre-biotically. The process is that of phosphorylation, i.e, adding a phosphate group to three key components of cells.

Human Kindness - In Bonobos!

A passer-by drops something and you spring to pick it up. Or maybe you hold the door for someone behind you. Such acts of kindness to strangers were long thought to be unique to humans, but recent research on bonobos suggests our species is not as exceptional in this regard as we like to think.

Oh Creation! Now An Intermediate Short-Necked Giraffe!
A new giraffid (Mammalia, Ruminantia, Pecora) from the late Miocene of Spain, and the evolution of the sivathere-samothere lineage
Another gap filled; another 'intermediate form' found!
So, do creationists give up with their disinformation, misrepresentation and downright lies? What do you think?
Of course not! It's just one more thing to misrepresent and lie about. A literal interpretation of the Bible says it shouldn't exist, so it doesn't exist! End of! FACT!
Anyway, back to the real world.
According to this report in the New York Times:

According to this report in the New York Times:
A near-perfect fossil unearthed close to Madrid appears to be an ancient European ancestor of giraffes, representing a new species in the family and one that had two sets of bony bumps on its head rather than the single set of modern giraffes.

Ancient Wisdom And Genetic Diversity
Neanderthal family group Photo credit: Nikola Solic/Reuters/Newscom |
Two papers published a few days ago in the same edition of Science show that hunter-gatherer people, both modern human and Neanderthal, had evolved cultures which minimised the genetic risks inherent in inbreeding in the small bands of which these groups consisted.
Small groups consisting only of related extended families would have a very high probability of consanguinity and inherited recessive genes unless they had strategies for regularly introducing genetic material from other more distantly related groups.

Gene Duplication Gave Us Spiders
Common house spider, Parasteatoda tepidariorum
The house spider genome reveals an ancient whole-genome duplication during arachnid evolution | BMC Biology | Full Text
For creationists still trying to get away with the absurd claim that mutations are always harmful and that no new information can arise in the genome because of the second law of thermodynamics, this is another of those bad news stories.
No! I'm not joking! They really do claim that! Creationists think nothing of claiming an observable thing can't happen, knowing that their willing dupes won't go and check. They'll no doubt continue to claim it even after this paper showing how the scorpions and arachnids have evidence of whole genome duplication in a common ancestor about 400 million years ago.

The Chemical Origin of Life
[left caption]
[right caption]
History of the ribosome and the origin of translation
A team of scientist from Georgia Institute of Technology, Atlanta, GA, USA believe they are close to solving one of the mysteries of how living systems first arose from chemical precursors. They believe they have identified a small section of the ribosome which is so fundamental that it is common to all living organisms, from the simplest single-celled organisms to the most complex multicellular plants and animals
In short, this looks to be the starting point for life and a structure that was present in LUCA and maybe before it.
Rather than the bottom up approach where scientists have attempted, with limited success so far, to reconstruct the fundamental units from which living systems could have arisen, the team took a top down approach by reverse engineering the cell organelle common to all living cells and therefore almost certainly present from the first moments, maybe even before something that could be called 'living' existed, the ribosome.

Cultural Woolly Mammoths
Eurasia Wooly Mammoth, Mammuthus primigenius
Male mammoths more often fell into 'natural traps' and died, DNA evidence suggests -- ScienceDaily:
Elephants are well known for the cultural organisation in which a matriarchal group, led by a older female who acts as a repository for group knowledge such as where the water may be found during a drought, etc. This group consists of females with their young but males, when they reach a certain age, generally fend for themselves in smaller groups or as solitary individuals often associated with but not members of a matriarchal group.
This, of course, deprives males of the protection of the group and of the knowledge and wisdom of the matriarch.
Now it seems Eurasian woolly mammoths, Mammuthus primigenius, may have had a similar social structure, suggesting that this may be a structure inherited from a common ancestors. This is a conclusion from the finding that young males are very much over-represented in the remains of mammoths which appear to have met an untimely, accidental death. The fossilised remains of mammoths which died of old age or due to predation are rarely found because they rarely fossilised. To become a fossil, a mammoth needed to be buried or submerged quickly, for instance by falling through ice on a frozen lake or becoming stuck in a bog they blundered into.
The team of researchers discovered this when analysing the DNA of Eurasia mammoths as part of another project, for which the sex of the individual needed to be know. When this disparity emerged, they decided to investigate further.

A New Species of Orangutan and More...
Orangutans in Sumatra's Batang Toru forest are now officially a new species: Pongo tapanuliensis. Credit: Maxime Aliaga/SOCP-Batang Toru Programme |
Not only is there great news about a new species of orangutan but the article in Nature announcing it quite casually shows how different strands of science all confirm current scientific understanding of evolution.
Firstly, the newly discovered orangutan (Pongo tapanuliensis).
Well, it's not exactly newly discovered so much as newly identified as a new species. It was first reported by western scientists about 50 years ago when they heard rumours of a population of orangutans living in a the Batang Toru forest in a remote part of the island of western Sumatra. However, it was not until anthropologist Erik Meijaard, that discovered the paper in the mid-1990s that scientists actually went looking for the population. They found the remains of a female, evidence of nests and a male killed by local people in 2013. From these, it was possible, using genetic evidence, to show not only that this was a new species, but how it relates to the other orangutans.

Animals Refute Creationism By Rational Thought
Cameron Buckner, assistant professor of philosophy at UH, says empirical evidence suggests a variety of animal species are able to make rational decisions, despite the lack of a human-like language. |
Do animals other than humans think rationally?
Cameron Buckner, assistant professor of philosophy at the University of Houston, think some at least do and believes he has evidence to support that view. His article is published a few days ago Philosophy and Phenomenological Research sets out his reasoning.
Regrettably, it sits behind an expensive paywall but a News release by Jeannie Kever of Huston University explains his findings:
"These data suggest that not only do some animals have a subjective take on the suitability of the option they are evaluating for their goal, they possess a subjective, internal signal regarding their confidence in this take that can be deployed to select amongst different options," he [Cameron Buckner] wrote.

Chimps More Like Us Than We Thought
Co-operating chimpanzees Credit: Christopher F Martin |
A new study by researchers from Oxford and Kyoto universities and Cincinnati Zoo has revealed a new level of co-operative behaviour not seen before in other than humans. The chimps were shown to be spontaneously taking turns co-cooperatively to complete a task, a form of behaviour believe to be basic to effective communication where timing cues are taken from one another.
As Dr Dora Biro, co-author of the study from Oxford’s Department of Zoology, said:
Coordinating behaviour is an essential component of many social situations and can enable groups of individuals jointly to solve problems. In communication, coordination often takes the form of turn-taking, where one individual takes cues from the other to decide on the timing of their own input. This can allow for the efficient exchange of information.

Zika - The Nasty Designer Plays it Sneaky!
Zika Virus Infects Developing Brain by First Infecting Cells Meant to Defend Against It
First, a little story:
God sat in Heaven gazing down at his creation that he loved and adored beyond measure and he noticed that things were not perfect. He notice all the war, famine, pestilence and hate.
He noticed that humans were finding cures for polio, smallpox, even malaria, and using antibiotics to cure infections that would have killed millions in earlier times. He noticed that very many children were growing up into strong, healthy adults when once they would have died in infancy.
He noticed though that there was still much suffering. He noticed the children born with physical and mental handicaps. He noticed the anguish of the parents of these children as they struggled to cope and make life bearable for these unfortunate children. He noticed too the deprivation suffered by the siblings of these children as their parents were forced to devote less time to them than they needed.
So he pondered on the problem and sat stroking his beard for many days, wondering what he could do about it. Why were things not as he would have wished them to be in his beloved creation? Had he not created it perfectly?
At last, a solution came into his mind.
So he improved antibiotic resistance in his bacteria and then he created the Zika virus. As a touch of brilliance, he created the Zika virus so it attacks and disables the cells that would have grown and developed into the victim's brain defences against pathogens.
"Let's see them cure that!", he thought. "Now, how's Ebola doing?"
Well, that's the creationist view.
Now let's look at the science.

Yet Another of Those Re-writes of Human Evolution?
Left: upper left canine. Right: upper right first molar Credit: Mainz Natural History Museum |
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
The skull of a Neandertal known as Shanidar 1 show signs of a blow to the head received at an early age. Photo: Erik Trinkaus |
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.

Lessons From a Canary Island - Spells and Incantations
Fan vaulting in the Cathedral of Santa Ana,
Las Palmas, Gran Canaria, Spain
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 20th 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 |
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. |
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

Tracing Plant Evolution Back To Its Roots
Common liverwort, Marchantia polymorpha |
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.

Old Fossils and the Crocodiles of Old England

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? Source: Wikipedia |
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
Monsignor Carlo Capella "Downloaded child pornography using a Canadian church online address". |
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.
