Modern human brain organization emerged only recently | Max Planck Society

The fossil record shows a distinct gradual transition to the modern human brain and cranial capacity from more ape-like origins, even within the species we recognise as Homo sapiens.

This is the finding of researchers from the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, according to an open access paper published a few days ago in Science Advances. The finding also illustrates nicely how science incorporates new information, even information that at first glance doesn't seem to fit what we thought we knew, and how that new information can lead to a revised understanding and an improved explanation.

New Poll - Creationism Declining in USA

In U.S., Belief in Creationist View of Humans at New Low

Slightly encouraging news a couple of days ago from a Gallop poll in the USA. I say slightly encouraging because the change is small on a small data set (just 1011 adults aged 18 or over) and the same poll is also disappointing in other ways.

The poll shows that belief in creationism as the best explanation for humans fell to 38%, the lowest since polling began in 1981 and below 40% for the first time.

However, a two percentage point fall is within the margin of statistical error on that size data set. None-the-less, it is encouraging - for the USA.

Modern Humans May Have Left Africa 200,000 Years Ago

Misliya-1

This ancient jawbone suggests our species left Africa 40,000 years earlier than expected | Science | AAAS

The story of when and where modern humans first left Africa is continuing to develop and looks like becoming more complicated than first thought when the evidence seemed to point to a single migration by a small group around 50,000 years ago.

A large international team led by Israel Hershkovitz from Tel Aviv University have concluded that the jaw bone found in a Misliya Cave on the western slope of Mount Carmel in Israel is that of a Homo sapiens, but that it is between 177,000 and 194,000 years old. This is some 40,000 years earlier than modern humans were believed to have left Africa to begin their world-wide dispersal. The previous earliest H. sapiens remains were those found nearby in the Skhul Cave on Mount Carmel and Qafzeh Cave in Israel, dated to between 80,000 to 120,000 years old.

How Creationists Lie To Us - Creation Ministries

When you show the world you need to lie for your faith
You show the world you know your faith is a lie

The meme on the right recently popped up in a Facebook group.

It is of course a lie.

The lie originated in one of the usual creationist disinformation sites, Creation.com, the online front for Creation Ministries, the Australia-based creationist organisation from which Ken Ham split when he realised America was a more lucrative place for scamming fundamentalist Christians, in an article penned by Jonathan O'Brien, a Creation Ministries staffer.

O'Brien is notorious for, amongst other things, his claim that the primitive carving of a rhinoceros in front of some leaves at Angkor Wat in Cambodia is really a carving of a stegosaurus, a creature with which it has little resemblance, and the claim that because a volcanic cone in Mexico grew in a year, this is evidence that mountains did not take millions of years to form, so could all have formed in the last few thousand years (ignoring the fact that most mountain ranges are not volcanic in origin but are due to plate tectonics).

Pope Attacks Sex Abuse Victims.

Bishop Juan Barros

Pope accuses sex abuse victims of slander

In an astonishing end to his less than triumphal visit to Chile, Pope Francis shocked his hosts by, not to put too fine a point on it, calling those accusing a Catholic Bishop of assisting a cover-up of child abuse, liars.

His visit had been met with demonstrations and much smaller crowds than previous visits because the Catholic Church in Chile is currently embroiled in the now traditional clerical sex abuse of minors scandal. Police had to use tear gas and water cannons to break up one demonstration outside the Pope's open-air address in the centre of Santiago.

Neanderthals Had Sex With Anyone

The Montmaurin-La Niche mandible reveals the complexity of the Neanderthals’ origin | CENIEH - Centro Nacional de Investigación sobre la Evolución Humana

We now know that modern humans interbred with at least two, probably three and possibly more different hominin species when they left Africa. What this new analysis shows is that Neanderthals also interbred with archaic hominins and may not even have formed as single lineage in Eurasia.

Instead, this analysis by a team of scientists from the Centro Nacional de Investigación sobre la Evolución Humana (National Research Centre for Human Evolution - CENIEH) in Spain, led by José María Bermúdez de Castro, together with the French researcher Amélie Vialet, from the Musée d'histoire naturelle (Natural History Museum) in Paris, suggests that Neanderthals may have diversified, evolved as isolated populations, then interbred with one another so that later Neanderthals were a mosaic of earlier and divergent populations.

Birds of a Feather - New Species Evolve

Large cactus finch (Geospiza conirostris)

Study of Darwin's finches reveals that new species can develop in as little as two generations

Birds of a feather: U of T researchers discover Amazon bird to be rare hybrid species

This week we have a couple of examples of new species arising - that thing that creationists insist can't happen. The evolutionary process that created them was hybridisation which occurs very much faster than the more usual (at least in vertebrates - speciation by hybridisation is common in plants) divergence by a combination of genetic drift and natural selection. And in these cases, the species are birds.

The first is from those devil figures for creationists - Darwin's finches or Galapagos finches. This was originally reported and commented extensively upon last November and revealed an observed incidence of apparent speciation when a vagrant male appeared on the island of Daphne Major. This was much larger and had a larger, more robust beak than any of the other three species present on the island. It also sang with a different song.

Two More Catholic Clerics - Two More Sex Abuse Scandals

Guam archbishop faces new sexual assault allegation | CRUX

The US Pacific territory of Guam, which is almost wholly Catholic, has been rocked by a series of allegations that vehemently homophobic Anthony Apuron, Archbishop of Agana, sexually abuses altar boys in the 1970s. He has vigorously denied all the allegations and has not been criminally charged, but now another accuser has come forward.

The latest accuser, a relative of Archbishop Apuron, has claimed in the local media that he was abused by Apuron in 1990. This latest allegation has been reported to the Vatican. According to Archbishop Michael Byrnes, an earlier Vatican tribunal investigation into the earlier allegations has reportedly concluded and reached a verdict late last year but, for reasons unknown, has not yet made its findings public. Archbishop Byrnes has been given administrative responsibility for the diocese while Apuron is on administrative leave.

Changing Our Mind When the Evidence Changes

To a creationist, with their simplistic black vs white, right vs wrong mentality, the fact that science can make mistakes or that the understanding is provisional - and all scientific understanding is provisional, even the best-supported - tells them that science, unlike their firmly held and unchangeable dogmas, is unreliable and therefore wrong. Little better than a guess, in fact.

To a scientist, and to anyone interested in truth rather than simple certainty, however, discovering that you have been wrong is actually welcome news and news that was well worth doing the research to discover because it means that what you now think you know is closer to the truth than it was before. Science works because scientists can and do change their minds when the evidence changes, unlike fundamentalist religions, where not changing your mind and not even questioning the dogmas is a prerequisite.

Massive Evolutionary Reduction in Genome Size

UM Publishes Research on Unusual Gene Evolution in Bacteria - UM News - University Of Montana:

Hopefully getting back to blogging again after spending time on another book, it's a pleasure coming back with details of two papers published by the same team a few days ago that shatter so many creationist dogmas, it's hard to keep count.

Creationists will tell you, for example, that evolution involves an increase in complexity and therefore an increase in information in the genome, and that this is impossible because of some mysterious application of the Second Law of Thermodynamics which ignore the fact that an organism, Earth, and even the solar system are not closed systems. Never-the-less, they'll confidently assure you that in this way science has proved evolution can't happen, it's just that millions of working biologists never got the memo and have been mistaking the observed instances of not evolution for examples of... well... evolution.

Moose on Isle Royale, Michigan, USA are evolving rapidly in response to environmental change, especially climate change.

Unlike nearby populations of moose which have halved in the past 12 years, the Isle Royale moose population has increased by more than twenty percent per year for the last six years - but they are getting smaller. Measurements of skulls collected over a forty year period show they have shrunk by about sixteen percent. Life-span is also reducing.

When a nun caring for children at the Catholic-run Smyllum Park children's home in Lanarkshire, Scotland walked into the chapel and found a priest sexually abusing an eight year-old girl, she sprang immediately into action.

She grabbed the girl by one arm and flung her against the wall, breaking her arm, called her a 'whore' and shouted “get the f*** out of here” at her.

Pope Francis has been thinking.

No, it's not about how the church can avoid taking responsibility for the child abuses carried out by it's priests and nuns and certainly not about how it can compensate and support their victims and avoid creating any more.

It's about how to resolve a curious contradiction in the Bible that has been taxing the brains of theologians and biblical scholars for close on 1700 years, ever since the Bible was compiled. The contradiction is between James 13:1 with:

One of the exciting things about science is how knowledge is never fixed and unchanging. It grows and develops as new findings are incorporated into existing understanding, sometimes even needing quite fundamental revisions of what we thought we knew.

One such branch of science is that of human evolution and dispersal out of Africa which is in an exciting phase at the moment as new archaeological discoveries are made and new techniques of DNA recovery and analysis are revealing genetic evidence of relationships and interbreeding.

Plagiarists For Jesus

Willaim Lane Craig. Accused of plagiarism

Christian Apologist William Lane Craig Accused of Plagiarizing Thesis.

In an article published yesterday by David G. Mcafee in the Patheos blog, No Sacred Cows, Christian apologist and apologist for faith-based genocide, William Lane Craig has been accused of plagiarising his Masters Degree thesis.

This accusation is not new; it has been around for several years, but has been given another airing by atheist, author and former student of William Lane Craig's, John W Loftus. Loftus has written extensively about Lane Craig's cowardice in refusing to debate him publicly despite Lane Craig making an issue of Richard Dawkins' refusal to give him a platform following his repugnant apologetic for the Canaanite genocide in which he presented infanticide as morally justifiable.

A Loving Nativity Scene That Christians Hate

Religious Conservatives Outraged By Gay Nativity ‘Sacrilege’

Apparently, conservative Christians are queuing up to be outraged by a Christmas nativity scene in a Los Angeles front garden that shows Jesus with two fathers.

It's not the pretty pink matching costumes that they're wearing but the fact that there are two of them which is causing the great gnashings of teeth and calls for retribution on the grounds of 'blasphemy'.

It was this Twitter tweet by Twitter user Cameron Esposito which sent them into a frothing-mouthed, venom-spitting spectacle on the social media.

But how is this a blaphemy? Isn't this exactly what the Bible says when it claims Jesus was the son of God, even making great play of the claim and basing the entire Christian religion on that claim, and also claiming Jesus was the son of Joseph and thus of the 'House of David' in fulfilment of a prophecy?

Bigots Kicked Down Under!

The Senate Just Voted Down All The Conservative Amendments To The Same-Sex Marriage Bill

Following the stunning victory for basic human decency and those campaigning for an inclusive Australia in the same-sex marriage referendum recently, the Australian Senate handed out another kicking to the Christian bigots still looking for victims and demanding the right to persecute people of their choice.

According to this report by Lane Sainty in Buzz News, the Senate voted down by a large majority a series of amendments by the conservative Christian right that would have given Christians an effective veto on same-sex marriages and provided them with a legal right to continue to persecute and victimise homosexuals by denial of goods and services.

Still Not Yeti

Abominable Snowman? Nope. Study ties DNA samples from purported Yetis to Asian bears

Just like their religious myths, the myth of the Yeti is a central part of the folklore of Tibet and Nepal. In that respect if differs not at all from other mythologies, religious or otherwise from other parts of the world. Lots of anecdotes and stories of people who knew of someone who's acquaintance once met someone who saw a Yeti or accounts of people seeing a shadow in a blizzard.

In the case of the Yeti, however, there was maybe something a bit more substantial - a tuft of hair, some faeces, skin, teeth, even a bone or two.

The problem is, the people who purportedly found these bits of evidence and sold them to collectors and Yeti hunters never counted on modern forensics and especially nor on modern DNA recovery and analysis.

Muddling Through With 'Intelligently Designed' Mistakes!

Adaptive mechanisms such as activation and use of cryptic splice sites or alternative transcription start sites as well as nonsense-associated alternative splicing and skipped exons maintaining reading frame shore up a sea of mutations expected to cause premature translation termination and loss of function.

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.

According to the Carnegie Institution press release:

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.

Zimbabwe: Who is the Catholic priest behind Robert Mugabe? | Christianity today

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 Mladic jailed for life over Bosnia war genocide - BBC News

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

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!

Two 'World Views'

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!

Australians back gay marriage in non-binding vote - BBC News:

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".

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

The Camino de Santiago de Compostela

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.

Anyway, back to the real world.

Ancient genomes show social and reproductive behavior of early Upper Paleolithic foragers | Science

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.

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.

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

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.

Newly discovered orangutan species is also the most endangered : Nature News & Comment

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 Think Rationally? - University of Houston

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

Chimpanzees shown spontaneously ‘taking turns’ to solve number puzzle | University of Oxford

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.
