Creationism in Crisis - Signs of Life on an Exoplanet 120 Million Lightyears Away.

This illustration shows what exoplanet K2-18 b could look like based on science data. K2-18 b, an exoplanet 8.6 times as massive as Earth, orbits the cool dwarf star K2-18 in the habitable zone and lies 120 light years from Earth.
In this illustration, the exoplanet K2-18 c is shown between K2-18 b and its star.

Abiogenesis, like the conditions that produced the Big Bang, is one of creationism's favourite gaps in which they try to fit their ever-shrinking little god and play their false dichotomy fallacy - if science can't explain it, "God did it!".

That ploy depends for its success of a couple of things, not the least of which are scientific illiteracy and cultural chauvinism of their target dupes. Creationists, while telling their targets that science can't explain how abiogenesis occurred, then pretend they know anyway and have calculated the probability of it. Of course, without knowing the precise conditions and chain of events, it is impossible to do that calculation, but nevertheless, creationist frauds will confidently proclaim it to be infinitesimally small.

However, if the precise mechanism were known, and the conditions could be replicated (temperature, pressure, catalysts, chemicals and time) the mechanism would not be impossible, it would be inevitable (i.e., certainty) since it is a basic principle of chemistry that if the conditions are right, a reaction will occur. No ifs or buts, it will occur since chemical reactions are not governed by laws of probability but by laws of physics. No chemist has ever needed to set up ten thousand test tubes to ensure at least one will produce the expected result. He/she would get ten thousand identical results.

But now, as scientists improve their ability to detect and examine the atmosphere of distant exoplanets orbiting other suns in the galaxy, so they are improving their ability to detect the inevitable signs of life on those planets and many people think it is only a matter of time before we have strong evidence of life elsewhere in the universe.

Conspiracy Loon News - Why Some People Fall For Wackadoodle Conspiracy Theories

They fall more easily for conspiracy theories - Linköping University

In the last 20 years of so, two things have featured in western culture, especially so in the United States, and recent research has shown how these are linked.

1. Democratization of opinion: Conflation of the belief that everyone is entitled to their opinion on every subject under the sun, as guaranteed to Americans by their constitution, and the belief that this means every opinion should carry equal weight in a debate, regardless of the evidence (or lack of it) on which it is based, or the level of expertise in the subject of the person voicing that opinion.
   
   The attractiveness of this belief to the intellectually lazy and to those who feel alienated by the political and economic forces that shape their lives, is that they can tell themselves that they are at least the equal of the experts, and very probably their better.
   
   For example, I was recently castigated in the social media when I disagreed with the claim that "everyone needs Jesus because without Him life is meaningless". I was informed that "This is America (it was actually Facebook!) where we are entitled to our opinions!", as though a constitutional right in one country mandates the rest of the world to respect dogma and regard it as a statement of irrefutable truth, with the implication that no-one has a right to disagree. The constitution guarantees my right to my opinion (but not your right to yours).
   
   Similarly false claims are made by creationists daily in social media, accompanied by indignation when challenged. Creationists who couldn't define the terms 'evolution' or 'kind' and who assiduously maintain their scientific ignorance, will confidently inform the world that the millions of highly qualified working biomedical scientists who have no difficulty with the science, have it all wrong, and should listen to the creationist who knows best, having completed a 15 minute Google University degree in creationism. And they're all part of a gigantic Satanic conspiracy anyway.

Pollution News - How Road Vehicle Tyres Are Polluting Our Waterways

Tyre wear particles are considered by environmental scientists to be one of the most significant sources of microplastics in the ocean.

Bit by bit microplastics from tyres are polluting our waterways – Griffith News

Back in the late 1960's, when I was a student at Oxford Polytechnic (Now Oxford Brookes University) studying for an HNC in Applied Biology, one of the modules (on which apparently the National Council for Academic Awards (NCAA) insisted) was 'General Studies', i.e., anything which broadened our education away from the narrowness of a specialised subject, such as Applied Biology.

Part of that was an assignment to investigate an aspect of man-made environmental pollution, Rachal Carson's 'Silent Spring' being a recent publication and a nascent green movement beginning to emerge. The subject I decided on was to investigate what happened to the millions of tons of vulcanized rubber from road vehicle tyres that needed to be replaced annually because tyres wore away on the roads. It stood to reason that that rubber either entered the atmospheres as dust, or, more likely, got washed off the roads and into road-side ditches and eventually into the waterways and from there to the sea.

The question was, what effect did this fine rubber dust have on the environment and how much of it ended up in the food chain?

I was shocked to discover, after several days searching the literature available to me in the college library (if only we had had the Internet in those days!) that there was not a scrap of scientific data on the subject. There were no published papers on the question whatsoever. Either no-one had thought it worth investigating, no-one had identified the problem, or no-one was prepared to fund the research. And yet millions of tons of vulcanized rubber were being turned into tyres and from then into rubber dust on our roads, and it was all going somewhere, but no-one knew where!

In desperation, and with a project to complete, I abandoned my research and instead looked at the environmental effects of DDT, then extensively used as an insecticide, and about which some alarming news was emerging - extermination of brown pelicans in American lakes treated with DDT to kill mosquitoes, because DDT is adsorbed onto particulate matter which is ingested by the small organisms eaten by fish and so concentrated up the food chain, at the apex of which were brown pelicans; loss of peregrine falcons because DDT reduced egg shell thickness, leading to a loss of broods, again the result of DDT being concentrated up the food chain and killing the apex predators.

So, news that, some 54 years later, researchers at Griffin University, Australia, have published a paper in Environmental Science & Technology, dealing with a closely related problem - the problem of microplastics and tire [sic] wear products in urban stormwater.

Sadly, the research paper is behind a paywall, but a Griffin University news release explains the research and its significance:

Malevolent Designer News - Is Creationism's Divine Malevolence Planning the Next Pandemic?

News - Bird flu is undergoing changes that could increase the risk of widespread human transmission - University of Nottingham

On top of a couple of recent papers showing creationist dogma to be false and that, if there were such a thing as an intelligent designer of living things, that designer can only be regarded as a malevolent monster, we have another paper which, if we believe creationist dogma, again shows their divine creator to be an obsessive, sadistic psychopath.

It is the news that scientists at Nottingham University, UK., and China have discovered how the variant of the H3N8 avian flu virus which is endemic in Chinese poultry farms, is mutating in a way which could make it more likely to cross the species barrier into humans and become the next pandemic.

What is the H3N8 Avian influenza virus and what threat does it pose to humanity?

H3N8 Avian influenza, also known as avian flu or bird flu, is a subtype of the influenza A virus that primarily affects birds, especially waterfowl and shorebirds. It is one of several subtypes of avian influenza viruses, each identified by specific combinations of surface proteins: hemagglutinin (H) and neuraminidase (N). In the case of H3N8, it refers to the third type of hemagglutinin (H3) and the eighth type of neuraminidase (N8) found on the virus's surface.

While H3N8 avian influenza primarily affects birds, it has the potential to pose a threat to humans under certain circumstances. Here are some key points to consider regarding its potential threat to humanity:

1. Zoonotic Transmission: Avian influenza viruses, including H3N8, are zoonotic, which means they can infect humans when they come into close contact with infected birds or contaminated environments. Most human cases of avian influenza have resulted from direct or indirect exposure to infected poultry.
2. Limited Human Infections: H3N8 avian influenza has not been as widely reported in human infections as some other avian influenza subtypes, such as H5N1 and H7N9. However, there have been occasional cases of H3N8 avian influenza infection in humans, often associated with direct contact with infected birds.
3. Potential for Adaptation: Avian influenza viruses have the ability to mutate and potentially adapt to human hosts. If a strain of H3N8 were to acquire the ability for efficient human-to-human transmission, it could lead to a more widespread outbreak or even a pandemic. This is a significant concern with avian influenza viruses in general.
4. Influenza Pandemic Preparedness: Due to the risk of avian influenza strains causing pandemics, public health organizations and governments worldwide monitor and study these viruses closely. Preparedness plans and strategies are in place to respond quickly to potential outbreaks, including the development of vaccines and antiviral medications.
5. Importance of Surveillance: Surveillance of avian influenza in both bird populations and humans is crucial to detect any changes in the virus's behavior or its potential to infect humans more easily. Timely identification and containment of outbreaks are essential to minimize the risk to public health.

In summary, H3N8 avian influenza is primarily a bird virus, but it can infect humans in rare cases. The main threat it poses to humanity lies in its potential to evolve and adapt to human-to-human transmission, potentially leading to a wider outbreak or pandemic. Vigilant surveillance, early detection, and preparedness are key components in mitigating this threat and preventing a significant public health crisis.

As explained in a Nottingham University news release, the evidence comes from an isolate of the H3N8 avian influenza virus (AIV) recovered from a human patient:

Malevolent Designer News - How Creationism's Favourite 'Designer' Made Alzheimers More Likely

[left caption]

IU researchers identify new gene mutation that alters Alzheimer’s disease risk

The terrible week for creationism continues unabated: Following yesterday’s news of more evidence of common descent of the great apes, including humans, we have news that creationism's putative designer has apparently given some people a gene variant that increases their risk of developing Alzheimer’s dementia in later life, while some others get a variant the reduces that risk.

A problem of creationists' own making is the insistence that mutations don't happen by chance but need the deliberate intervention of their favourite putative designer, without whom nothing happens.

This means they need to ignore the existence of parasites, which, if they were designed deliberately, can only be regarded as evidence that whatever designed them had malevolent intent, and intended to increase the suffering in the world, since that is what they do.

It also means they need to ignore the evidence that a lot of diseases are caused by mutations, especially the degenerative diseases in older people, which don't manifest until after they have produced their offspring, and so passed on their genetics, including any mutations.

This is where we come to the news that a large team of researchers, led by scientists from Indiana University School of Medicine, USA, have identified a mutation in a critical gene for the brain's immune system, so greatly increasing the risk of developing Alzheimer's.

Creationism in Crisis - How Human Shoulders and Elbows Show Our Common Ancestry With Chimpanzees

Our Shoulders and Elbows Began as Brakes for Climbing Apes | Dartmouth

Every week is a bad week for creationists but this one is shaping up to be especially bad, with a clutch of peer reviewed papers which either show creationist is a counter-factual superstition, or that any putative designer can only be regarded as a malevolent entity, forever plotting new ways to make its creation suffer with more effective parasite.

The first of these is a paper by Dartmouth researchers, published in The Royal Society Open Science, which shows that the human shoulder and elbow joints probably evolved in an arboreal ape ancestor on the evidence that chimpanzees have the same adaptations.

The adaptations evolved to act as brakes as the apes lowered themselves from trees, reducing their chance of falling or injuring these joints because of their relatively large bodies.

The research, and its significance for understanding human evolution, is explained in a Dartmouth news release:

The thing about science is that it is supported by evidence and one of the best pieces of evidence is when something predicted by a theory turns out to be true.

And one of the things predicted by the Big Bang is massive objects produced by 3D ripples found in the material of the early universe, known as Baryon Acoustic Oscillations (BAO).

Whole Genome Duplication and Gene Evolution in the Hyperdiverse Venomous Gastropods | Molecular Biology and Evolution | Oxford Academic

Creationist dupes will confidently tell you that genetic information can only be created with the intervention of a magic, supernatural creator because, so they claim, information theory says, no new information can arise because it's somehow analogous to the creation of energy which the First Law of Thermodynamics says can't be created.

Press them to explain why they think information is analogous to energy and they'll break off the conversation and run, usually with departing abuse or smug condescension.

They will also confidently tell you that all mutations are deleterious, so evolution is either impossible, or 'devolutionary' [sic] (© Michael J Behe).

So, show them examples of increase in genetic information being part of the explanation for evolution in some taxons because the real world has no difficulty duplicating all or part of a genome then letting natural selection select for advantageous mutations in the duplicated genes, and they'll go into denial mode or pretend to be too stupid to understand.

These examples abound in nature and most species will have remnants of gene duplication in their genome. An example of the role it played in the evolution of a highly diverse class of mollusks, the marine gastropods, many of which are venomous.

Covidiot News - How ChatGPT is Dispelling Anti-Vaxx Disinformation

ChatGPT is Debunking Myths on Social Media Around Vaccine Safety, Say Experts - Taylor & Francis Newsroom

According to a very recent report in the peer-reviewed journal, Human Vaccines & Immunotherapeutics, the artificial intelligence chat bot, ChatGPT, is helping to dispel some of the myths surrounding vaccines, by providing the factual information that debunks the myths.

Having had all our COVID-19 vaccinations, including any seasonal boosters, and having just recovered from a mild, but unpleasant bout of it which my partner and I probably caught in France or during the flight back, I thought I would put this to the test with a little research of my own:

Creationists claim, without any understanding of the biological absurdity of the claim, that the human population on Earth went through a genetic bottleneck of 8 related individuals about 4,000 years ago following a genocidal flood inflicted on Earth by an angry god, annoyed that his design wasn't working as intended.

The one thing right about that claim is the bottleneck, although it wasn't so narrow that it would have almost guaranteed extinction within a few generations because of accumulated deleterious genes and a lack of genetic diversity, it was about 1,280 individuals and it happened about 900,000 years before creationists believe the universe was created, before anatomically-modern humans had evolved.

This is the findings of Chinese researchers led by Haipeng Li, of the Chinese Academy of Science (CAS) Key Laboratory of Computational Biology, Shanghai Institute of Nutrition and Health, and Yi-Hsuan Pan of the Key Laboratory of Brain Functional Genomics of Ministry of Education, School of Life Science, East China Normal University, Shanghai, China.

First, a little about evolutionary bottlenecks and the consequences for humanity had the mythical genocidal flood actually occurred as creationists believe:

The age of the universe is guaranteed to get creationists tying themselves in knots while performing the most contorted mental gymnastics ad foaming at the mouth. Their problem is that they have been conditioned to dismiss scientific dating by chanting mindlessly about all radiometric dating methods being wrong because radioactive decay rates changed over time and dating the same sample by different methods gives different results.

The latter point, to a creationist, is the clincher because, to a simplistic, black vs white, thinker any discrepancy means the entire process is wrong and therefore its rational to argue that they can make 8,000 years look like several billion years.

But their problem is, dating the age of celestial objects such as the Ring Nebula does not rely on radiometric dating. Astronomers use a variety of methods to calculate the distance of the object from Earth, or in this case the JWST:

Flowering for naught: 120 years with nothing to show | Hiroshima University

If you want an example of something that no even half competent, intelligent designer would come up with, but exactly the sort of thing a mindless, undirected, utilitarian process such as evolution by natural selection, can produce, you need look no further than bamboo.

Bamboo is monocarpic, i.e., like many annual and biennial plants it flowers once, then dies. However, unlike most monocarpic plants that take just one of two, maybe a few years, to flower, bamboo of the variety hedonis takes 120 years.

To make matters worse, because they all germinated at the same time after the last flowering, all the bamboo plants in the local area flower and die at the same time, devastating an ecosystem that had been forming for 120 years, as food crop, and even providing raw materials for local crafts. And then it's gone, reverting to grassland for the three or more years it takes for the new generation to reestablish itself.

As though that weren't bad enough, researchers at Hiroshima University have now shown that there is a very low success rate in germinating seeds as most of them are sterile and fail to germinate.

The last time this variety of bamboo flowered was in 1908, so, in a few years, there is a very real risk that var. hedonis could become extinct.

The problem is explained in a Hiroshima University News release:

Sahara space rock 4.5 billion years old upends assumptions about the early Solar System

According to creationists, a magic supernatural god magicked a flat Earth into existence from nothing and put a dome over it to keep the water about the sky out. It then hung a sun and a moon from the dome and the sun has been orbiting Earth ever since. In its Bronze Age account of this creation, the magic god 'forgot' to say where the sun went at night, and creationists have puzzled over that problem for centuries, never reaching a conclusion.

Nowadays, 25% of Americans still believe Earth is the centre of the universe and the sun orbits it, although most of them now accept that Earth is no longer flat or has a dome over it, whilst believing the Bible, which says otherwise, is the inerrant word of the god who created everything from nothing.

Science, on the other hand, is providing evidence that the universe is some 14 billion years and the solar system, with the sun at the centre and Earth orbiting it, formed some 4.5 billion years ago.

One of the pieces of evidence is a meteorite, recovered from a sand dune in the Saharah Desert which has been dated to 4.5 billion years old, using the aluminium-26 – magnesium-26 (26Al-26Mg) decay system combined with the Uranium/Lead system.

First, a little AI information from ChatGPT3.5 about the dating methods used, their accuracy and limitations. Creationists especially might want to skip this since it refutes many of their claims about radiometric dating in general, and shows their responses to be parrot squawks, regurgitated on cue without the slightest understanding of the subject:

Creationism in Crisis - Scientists Use Algae to Work Out How Plants Evolved in 600 Million Years

Closest to the first algae to colonize the land

Press release: Algae provide clues about 600 million years of plant evolution

No doubt to the discomfort of creationists, a team of researchers led by Professor Jan de Vries of the University of Göttingen, Germany, have worked out how terrestrial plants have evolved in the 600 million years since the first marine algae colonize the land. This colonization is believed to have occurred just once, so all terrestrial plants are descended from that single colonizing species.

Note the question was not whether, but how this evolutionary process occurred. There was never a shadow of doubt that it was an evolutionary process in which there was no evidence of magic or supernatural interference with chemistry and physics.

Using the results of a series of experiments that have been running in the research lab in Gottingen for over 25 years, the team were able to identify key evolutionary changes that occurred as a prequel to land colonization and which are still to be found in terrestrial plants after 600 million years of evolutionary diversification.

Creationists must now draw on their repertoire of rehearsed dismissals of the science to cope with these finding and maintain the myth that land plants were created as is in one day about 8000 years ago, and have not evolved since:

• Redefine evolution ("They're still plants!").
• The dates are wrong ("Radiometric dating is flawed; it wasn’t hundreds of millions; it was just hundreds of years!").
• The scientists are lying ("It's a Satanic conspiracy to turn people away from Jesus!")

First, a lttle AI background:

Three-eyed distant relative of insects and crustaceans reveals amazing detail of early animal evolution | News | University of Leicester

A team from the University of Leicester, Yunnan Key Laboratory for Palaeobiology and the Institute of Palaeontology at Yunnan University, Chengjiang Fossil Museum, and the Natural History Museum in London, have redescribed a unique fossil animal from rocks nearly 520 million years old that fills in a gap in our understanding of the evolution of animals known as arthropods.

The animal, Kylinxia zhangi, simply shouldn’t be there if creationists claims were true. It is from almost 520 million years before Earth and the life on it was created and its one of those 'transitional' species showing characteristics of not just two different species, but two entire classes of the arthropod phylum. As such, of course, they are evidence of the evolutionary common origin of those two classes within the major taxon.

They're the sort of species that would have any creationist scratching their heads and declaring, "But they're still er... insects.... er... crustaceans"! before hurriedly redefining 'kind' as a major taxonomic class that includes hundreds of thousands of disparate species with different appendages and body plans of the sort that the same creationist will assure you can't have evolved because 'macro-evolution', i.e., evolving new appendages, body plans, etc., is impossible, while 'micro-evolution, i.e., evolution within the same 'kind' is now perfectly possible. 25 years ago, it was impossible until they realised no Ark could be big enough to contain 2 (or 7)of each known and extinct species.

So, the standard knee-jerk response will be necessary: the scientists lied; the scientists got the dates wrong; the dating techniques are flawed; the scientists are part of a world-wide satanic conspiracy to turn people away from Jesus - even the Chines scientists for whom Jesus and Satan are as mythical as are the Chinese Taoist gods to an American Christian fundamentalist.

But, leaving aside the arrogant cultural chauvinism in assuming the locally popular god in America is the only real one, I wonder how many creationists can explain why the dating methods used were wrong by many orders of magnitude, returning dates in the hundreds of millions of years when the real date should have been about 4,000 years.

The find and its significance is explained in a University of Leicester news release:

Auckland wastewater pipe dig reveals 'fossil treasure trove' - Taylor & Francis Newsroom

Not only is the age of these marine fossils a problem for creationism, so is the composition. It's a central dogma of creationism that all fossil deposits and rock strata are the result of a single genocidal flood in which 'all living substance' was destroyed - including and especially terrestrial animals, so any deposit of fossils resulting from that alleged flood should contain terrestrial species and plants. Not only that, but they should be from all over the globe, not just the local fauna because in a global flood there would be no barriers and dead animals would be free to float anywhere.

And yet here we have a fossil deposit consisting wholly of marine species from a particular time, found in a narrow range of habitats local to New Zealand at that time. There are no Eurasian, African or American species and not even any Australian species - from just a short float away.

The fossils were found by workers laying a new wastewater pipeline in a major civil engineering project. The find and its significance is described in research paper in the Taylor & Francis journal New Zealand Journal of Geology and Geophysics and an accompanying news release by Taylor & Francis:

Unintelligent Design News - How the Human Y Chromosome Evolved

Rost9/Shutterstock

The 'weird' male Y chromosome has finally been fully sequenced. Can we now understand how it works, and how it evolved?

An international team of scientists led by researchers from the National Human Genome Research Institute, National Institutes of Health, Bethesda, MD, USA, together with colleagues from the University of California Santa Cruz, Santa Cruz, CA, USA, the University of Connecticut, Storrs, CT, USA, Johns Hopkins University, Baltimore, MD, USA, have finally completed the task of sequencing the entire human Y chromosome from end to end or T2T (Telomere-to-Telomere). This completes the entire human genome now sequenced T2T.

Unsurprisingly, they found that most of the DNA was non-functional junk, containing the remnants of ancient retroviruses and duplicated genes that had then mutated.

The X and Y chromosomes, or sex chromosomes, are how gender is determined in humans and other mammals. Females have two copies of the X chromosome while males have one of each. Males inherit their Y chromosome from their father.

The significance of the research, and how it informs our understanding of the evolution of the Y chromosome from one of the two X chromosomes that females carry is the subject of an article in The Conversation by Professor Jenny Graves Jenny Graves, La Trobe University, Australia. Her article is reprinted here under a Creative Commons Licence, reformatted for stylistic consistency:

New ancient ape from Türkiye challenges the story of human origins | Faculty of Arts & Science

Science might have the human evolutionary story wrong. But before creationists get over-excited, no-one is suggesting it was all done by magic without any ancestors just a few thousand years ago. The new thinking is over the where, not the how of evolution. That humans and the other apes evolved from a common ancestor is not in any doubt. The question is only where that common ancestor lived - Eurasia or Africa?

This discovery in Turkey adds support to the idea that the African apes, including humans, evolved from an ancestor that migrated into Africa from Eurasia via the Eastern Mediterranean, between 9 and 7 million years ago, having evolved in Western Europe and lived there for some 5 million years.

The news release from the University of Toronto, where the leader of an international team, Professor David Begun, is based, explains the find and its significance for the human evolution story:

A characteristic of evolved systems is that they tend towards increasing complexity, the antithesis of an intelligently designed system, which should be minimally complex for the simple reason that complexity is expensive in terms of energy and resource, and more likely to go wrong.

Unnecessary complexity and prolific waste, which are normal components of evolved systems, are the strongest arguments against intelligent design and for a mindless, utilitarian, near-enough-is-good-enough, process such as evolution by natural selection.

And just such a case of quite ludicrous complexity has been revealed by Kenji Suetsugu of Kobe University Graduate School of Science, Kobe, Japan.

Sadly, the paper in Ecology is behind a paywall, however the research and its significance is the subject of Kobe University press release:

Deutsches Primatenzentrum: Bonobos grow similarly to humans

The problem creationists have with trying to maintain the myth that humans are a special creation by citing uniquely human traits, is that science keeps on showing that these are not unique after all, and in fact support the idea of common origins.

One such 'uniquely human' trait was thought to be the adolescent growth spurt where children have a rapid increase in height soon after puberty. Now researchers led by Dr. Verena Behringe of the Endocrinology lab at the German Primate Center (DPZ), Leibniz Institute for Primate Research, Göttingen, Germany, have shown that our closest relatives, bonobos, Pan paniscus, have a similar growth spurt at a similar stage in the development and that other primates may also have similar growth spurts.

Creationism in Crisis - Cave Art in Borneo From 35,000 Years Before Earth Existed (According to Creationists)

Gua Sireh, Sarawak, Borneo, Malaysia

Gua Sireh, Sarawak, Borneo, Malaysia

This cave on Borneo has been used for 20,000 years – and we’ve now dated rock art showing colonial resistance 400 years ago

According to creationists, about 8-10,000 years ago a god made of nothing made everything in the Universe out of nothing using nothing more than magic words. It also created humans and all the other animals a few days later. Then, in a fit of anger because its creation hadn't turned out the way it had designed it, it killed almost all of it in a genocidal flood, reducing the human population of Earth to just 8 related people.

While all that was happening, there were people using a large cave in Sarawak on the island of Borneo, in Malaysia from 35-43,000 years before Earth existed and up until and including European colonisation about 400 years ago. These people left a record of their existence and cultural history in the form of drawings on the cave wall. There is no record of a genocidal flood, and nothing about a god creating other people about 10,000 years ago.
But, according to creationists, just a few thousand years ago the island of Borneo was repopulated by people from the Middle East, who, although all descended from 8 related individuals of Middle Eastern origin, mysteriously adopted the same artistic style as the antediluvian population, forgot all about the genocidal flood and the god who caused it, invented their own gods and continued as though nothing unusual had happened.

That is the sort of mental gymnastics a creationist needs to perform to avoid the dreadful prospect of wondering if they could be wrong.

First, a little about the caves in Sarawak and the art and artifacts found in them:

It all depends on the genetic diversity | Max Planck Institute for Chemical Ecology

Mutations in genes that are essential for defence against predator attack are usually deleterious and would be expected to be quickly eliminated from a population, however, occasionally, the same mutation can convey an advantage which it is able to assert in conditions where predator populations are low, and this is especially true if wide genetic diversity within the population makes it more likely that the mutation can operate synergistically with other genes.

This can lead to a dynamic situation in which, in periods of low predation, the mutation can increase, or at least remain at a stable level in the population, and, in periods of high predation, it can be reduced. This dynamic can result in deleterious genes being retained in a population for much longer than would be expected if they were wholly deleterious.

An example of this was found recently by researchers from the Max Planck Institute for Chemical Ecology, Jena, Germany, in a wild member of the tobacco family, Nicotiana attenuata. Their finding is published in Proceedings of the National Academy of Science (PNAS)

The research and its significance are explained in a press release:

How Science Works (And Why Creationism Doesn't) - The Peer Review Process Explained

What exactly is peer review?

10 Stages of the Peer Review Process: A Step-by-Step Guide for Authors | The International journal of Innovative Research & Development

Creationist frauds tell their dupes that the scientific process of peer review, is a device to ensure conformity to scientific dogma and to prevent unorthodox (i.e., creationist) opinions from being published in respected journals.

This helps maintain the delusion that there is real scientific support for creationism and that many more scientists are really creationists than is apparent from the scientific literature.

It also plays to conspiracism, which is a normal component of creationism, caused by the same childish teleological thinking defect in an adult, by helping to maintain the delusion that scientists and publishers of scientific journals, periodicals and books, and their staff, are all part of a gigantic international Satanic conspiracy to turn people away from God and destroy people's trust in the church and the Bible.

The truth is that peer review is simply a device to ensure the research was conducted with sufficient rigor and proper controls, that the authors have provided the required standard of evidence to support their claims and that their conclusions are indeed supported by the evidence. It also helps insure against plagiarism since the expert reviewers will very likely be aware of the work of others in their field of expertise.

Here, for example is the peer-review process as outlined in a blog by the International Journal of Innovative Research and Development (IJIRD):

In an example of how the environment, and in this case probably the availability of different food items, can cause changes on which natural selection can act, a study by an international team or reserchers led by Pablo Salmón of Lund University, Sweden, has shown that great tits, Parus major living in an urban environment have paler breasts than those living in a forest environment.

Although this is probably not an evolutionary change, i.e., a change in the frequency of alleles in the population gene pools, as the cause is probably dietary difference, it illustrates how an environmental change can produce changes in features on which natural selection can act to bring about true evolutionary changes, and so begin the process of allopatric speciation.

Of course, there will be creationists who will misrepresent the scientific fact of evolution, either deliberately, or mendaciously in order to mislead others, who will dismiss this as "not evolution", not for the reason given above but because "they're still great tits/still birds" and haven't grown a new structure or turned into an unrelated taxon.

Wooded grasslands flourished in Africa 21 million years ago – new research forces a rethink of ape evolution

Scientists are changing their mind about when and why the ancestors of hominins evolved to walk upright - but it's no comfort for creationists, as it all happened 21 million years before they believe Earth existed and only needs the standard Theory of Evolution by Natural Selection to explain it.

There is no doubt about how it evolved. Needless to say, as always, the paleoanthropologists found nothing that needed magic or a supernatural deity to explain it.

The scientists have published their findings in two papers in Science, one by a team led by Daniel Peppe, Associate Professor, Department of Geosciences, Baylor University, and the second led by Laura M. MacLatchy, Professor of Anthropology, University of Michigan.

Creationism in Crisis - Fijian Folk Tale Has Nothing About a Global Flood or The God Who Allegedly Caused It!

Eruption remembered in riddles and fantastical oral traditions.

A dramatic volcano eruption changed lives in Fiji 2,500 years ago. 100 generations have kept the story alive

2,500 years ago, just 1,500 years after creationists believe the human population of the world had been reduced to just 8 people in a genocidal flood, there was a volcanic eruption on one end of the island of Kadavu in the south of the group of Pacific islands now known as the Fijian Islands.

The people who were already living there, having presumably migrated there from the Middle East in just 1,500 years, remembered the details of the eruption and passed them on, complete with the local gods to whom they attributed the events, not in writing, but encoded in riddles and a symbolic oral tradition which "included fantastic beings flying through the sky, fighting each another furiously and noisily, drinking the ocean dry, and throwing giant spears with force enough to leave massive holes in rocky headlands", according to research by a group of scientists including Professor Patrick Nunn of the University of the Sunshine Coast, Australia.

Curiously, if the Bible tales of a global flood had been true, people to whom a local volcanic eruption was such an important event in their history that they remembered it in such an elaborate way, regarded a genocidal global flood as not worth a mention, and the god who allegedly caused it as unworthy of inclusion in their pantheon.

This is the ludicrously unlikely scenario that creationists have to try to rationalise in order to avoid considering that their favourite Bronze Age fairy tales are anything other than literal truths.

Scientists Zero In On Timing, Causes Of Ice Age Mammal Extinctions In Southern California - Texas A&M Today

It’s hardly surprising anymore because all but the most recent history of Earth took place millions, even billions of years before Earth was created, according to Creationists’ literal reading of the Bronze Age creation myth recorded in the Bible, but here we have evidence of a sudden mass extinction in Southern California, not by a genocidal global flood, but by rapid climate change, human activity and devastating regional fires.

This is the conclusion of a detailed study by a team of scientists that included Texas A&M University archaeologist, Dr. Michael Waters. The team focused on the Rancho La Brea Tar Pits.

First a little AI information about the Rancho La Brea Tar Pits:

The Rancho La Brea Tar Pits

The Rancho La Brea Tar Pits, also known as the La Brea Tar Pits, is a famous fossil excavation site located in the Miracle Mile district of Los Angeles, California, USA. It is one of the most significant paleontological sites in the world and has provided an incredible wealth of information about the prehistoric life that existed in the region during the Pleistocene epoch. Here are some key points about the Rancho La Brea Tar Pits:

1. Formation: The tar pits were formed as a result of crude oil seeping to the surface from underground deposits. The oil would bubble up to the surface, forming pools of sticky asphalt or tar. These pools were often covered by water, leaves, and other debris, which attracted animals that became trapped in the tar.
2. Fossil Preservation: The unique conditions of the tar pits resulted in excellent preservation of the trapped animals. The tar's stickiness trapped animals, and the lack of oxygen and bacteria in the tar slowed down decomposition. Over time, bones and other remains of animals accumulated in the pits.
3. Prehistoric Fauna: The tar pits contain a wide variety of fossils, including those of mammals, birds, reptiles, and plants. Some of the most common animals found in the pits include dire wolves, saber-toothed cats, mammoths, mastodons, ground sloths, and various species of birds.
4. Research and Discoveries: Excavations at the Rancho La Brea Tar Pits began in the early 20th century. The first scientific excavations took place in the early 1900s, and since then, thousands of fossils have been recovered. These fossils have provided invaluable insights into the animals that lived in the Los Angeles area during the Pleistocene epoch, which occurred approximately 10,000 to 40,000 years ago.
5. Page Museum: The George C. Page Museum, now known as the La Brea Tar Pits and Museum, was established in 1977 near the tar pits. It houses a vast collection of fossils and artifacts recovered from the site. The museum also includes exhibits that provide information about the history of the tar pits, the animals that were trapped there, and the science of paleontology.
6. Active Excavations: Despite decades of research and excavation, the tar pits are still actively studied and excavated. New discoveries continue to shed light on the ancient ecosystem of the region.
7. Public Engagement: The La Brea Tar Pits and Museum offers educational programs, guided tours, and interactive exhibits for visitors of all ages. It's a popular destination for tourists, students, and researchers interested in paleontology and natural history.

The Rancho La Brea Tar Pits are a unique and invaluable resource for understanding the ancient history of Southern California and the diverse range of life that once inhabited the region. The site's ongoing excavations and research contribute to our understanding of prehistoric ecosystems and the interactions between humans and the environment during that time.

Creationism in Crisis - Finish Scientists Have Worked out How Modern Elephant Teeth Evolved - It Was Darwininian Natural Selection, Obviously!

Elephant ancestors´ teeth evolved in response to long term changes in diet and climate in Africa | University of Helsinki

In marked contrast to the childish creationists superstition that a magic supernatural man in the sky created everything as is, including Earth itself, about 8-10,000 years ago, two research palaeontologists at the University of Helsinki, Finland, have shown that the proboscideans, which includes modern elephants, their ancestors, and ancient relatives, evolved their teeth in response to environmental changes in East Africa over a period of between 20 and 7 million years ago.

They have published their findings, open access in the Journal, Nature Ecology & Evolution.

As we have come to expect, there is not a hint in their research that elephant teeth are the result of anything other than an evolutionary process, driven, as the Theory of Evolution predicts, by environmental change. There is never a hint that magic played any part in the process.

Thick ones, pointy ones – how albatross beaks evolved to match their prey

Just as Darwin's finch’s beaks did, albatross’ beaks have diversified as the different species diversified from a common ancestor, and the driving force is again the food they eat.

This is the finding of three biologists, Josh Tyler, a Postgraduate Research Student in the Department of Life Sciences, University of Bath, UK, Jane Younger, Lecturer, Southern Ocean Vertebrate Ecology, University of Tasmania, Australia and David Hocking, Adjunct Research Associate, Monash University, Australia.

And of course, it's bad news for creationists who have been fooled into thinking biologists are abandoning the Theory of Evolution in favour of their childish superstition with its belief in magic and supernatural deities.

Creationism in Crisis - In Just 2000 Years Humans In Central Asia Had Diverged into Multiple Cultures Each with Distinctive DNA, If Creationists Are to be Believed

Following the news that Ötzi the Iceman, who died just 700 years after creationists believe the human population of the world was reduced to 8 related individuals, was a brown-skinned 'outsider' in Europe, descended from people who had migrated from Anatolia a couple of thousand years earlier, comes news that an early empire in Central Asia, the Xiongnu Empire, had a multi-ethnic origin.

Each of these pieces of news give the lie to creationist claims of a genocidal flood just 4000 years ago because there would simply not be enough time for the human populations of Europe or Asia to diversify to the extent that different genetic populations would be identifiable.

Taken together, they mean even the traditional claim that the scientists knowingly used inaccurate radiometric dating is redundant. Ötzi was dated partly by dendrochronology, which is not a radiometric dating technique, and the dates of the Xiongnu Empire are from contemporaneous records kept by their neighbours in China.

First a little background, courtesy of the AI source, ChatGPT3.5:

The Xiongnu were a significant nomadic confederation that originated in Central Asia, particularly in the regions of modern-day Mongolia, Kazakhstan, and northern China. They played a crucial role in shaping the history and dynamics of the ancient Eurasian steppe region. Here are some key points about the Xiongnu:

1. Origin and Expansion: The Xiongnu are believed to have emerged around the 3rd century BCE and quickly established themselves as a dominant power in the steppe region. They were known for their skilled horsemanship and nomadic lifestyle, which allowed them to traverse vast distances and exert control over large areas.
2. Society and Culture: Xiongnu society was organized along tribal lines, with a hierarchical structure. They had a chieftain or "shanyu" at the top, followed by subordinate tribal leaders. Their culture was heavily influenced by steppe traditions, including horse riding, pastoralism, and archery. They were also known for their use of mounted warriors and chariots in warfare.
3. Conflict with China: One of the most significant aspects of Xiongnu history is their interaction with the Chinese dynasties, particularly the Han Dynasty. The Xiongnu frequently raided northern Chinese territories and established a tense relationship with the Han rulers. The Chinese even built the Great Wall as a defense against Xiongnu incursions.
4. Diplomacy and Alliances: Throughout their history, the Xiongnu engaged in both military conflicts and diplomatic negotiations with China. At times, they formed alliances or signed treaties with the Chinese in exchange for tribute or gifts. These interactions were often marked by a delicate balance of power and a mutual understanding of the benefits of maintaining stable relations.
5. Decline and Disintegration: By the 2nd century CE, the Xiongnu confederation began to weaken due to internal conflicts, external pressures, and changes in the geopolitical landscape. The rise of other nomadic groups, such as the Xianbei and the Huns, also contributed to their decline. Eventually, the Xiongnu fragmented into smaller groups, some of which merged with neighboring societies, while others faded into history.
6. Legacy: The Xiongnu left a lasting impact on the cultural and historical development of Central Asia and the surrounding regions. Their interactions with China influenced Chinese policies, military strategies, and diplomatic approaches. Additionally, the Xiongnu's nomadic lifestyle and military techniques contributed to the broader cultural and societal dynamics of the Eurasian steppe.
7. Historical Sources: Much of what is known about the Xiongnu comes from Chinese historical records and archaeological findings. Ancient Chinese texts, such as the "Records of the Grand Historian" by Sima Qian, provide valuable insights into the interactions between the Xiongnu and China.

Overall, the Xiongnu were a significant force in the ancient world, shaping the geopolitical landscape of Central Asia and leaving a lasting mark on the history of the region.

An interesting finding from the study is that genetic diversity was widest amongst the lower status individuals and much lower amongst the social elite, suggesting that a culture had developed where a narrow ethnic group had gained control of diverse populations.

And all this diversity in the two thousand years following the genocidal flood, is the Bible and its creationist advocates are to be believed. Clearly a preposterous proposition.

As with the genetic analysis of Ötzi the Iceman, the research into the origins of the per-Mongolian Xiongnu included scientists from the Max Planck Institute for Evolutionary Anthropology, Leipzig, Germany. As the Max Planck Institute’s newsletter explains:

Creationism in Crisis - Ötzi The Iceman Had Anatolian Ancestors

In about 3,300 BCE, some 700 years after Bible literalist creationists believe the human population was reduced to just 8 survivors of a genocidal flood inflicted on the world by their 'loving' God, a brown-skinned man, possibly being pursued over the Alps north of Italy, fell into a glacier. He may have died before he fell or he may have died of his injuries from the fall, but a fresh arrow wound in his shoulder may have contributed to his death.

The significance of his genome is that is shows how far the human population of Europe had diversified into distinct groups each with a characteristic DNA signature - something that would not have been possible if the entire human population of the world had evolved from such a narrow genetic bottleneck. Not only had they diversified but had developed distinct cultures and life-styles.

Another significance of this research is that it shows how science is never certain, but constantly reassesses the evidence and revises its collective opinion when the evidence demands it.

Ötzi the Iceman

Ötzi, also known as the Iceman, is a well-preserved mummy of a man who lived during the Copper Age, around 3300 BCE. He was discovered in the Ötztal Alps, hence the name "Ötzi," by German tourists on September 19, 1991, near the border between Austria and Italy. The mummy was found at an altitude of around 3,210 meters (10,530 feet) in the Schnalstal Glacier. Here are some key facts and details about Ötzi the Iceman:

1. Discovery and Preservation: Ötzi's mummy was preserved due to the unique conditions of the glacier, which acted as a natural freezer. His body was naturally mummified over the centuries, allowing researchers to gain insights into his life and the environment he lived in.
2. Age and Appearance: Ötzi was estimated to be around 45 years old at the time of his death. He stood about 1.6 meters (5 feet 3 inches) tall and had a stocky build. He had brown eyes, wore a beard, and had tattoos on various parts of his body, likely created by making small incisions and rubbing charcoal or other pigments into them.
3. Clothing and Equipment: Ötzi's clothing included a coat made of woven grass and leather, a loincloth, leggings, a belt, and a hat. He also wore shoes made of grass and leather. He carried a variety of tools and equipment, including a copper-bladed axe, a flint knife, a quiver with arrows, a backpack, a birch bark container, and a wooden bow.
4. Diet and Lifestyle: Examination of Ötzi's stomach contents and isotopic analysis of his teeth and bones provided insights into his diet. He primarily consumed a diet of meat (from ibex and red deer) and various grains and plants, including einkorn wheat. This indicates a diet typical of the time, as well as evidence of mobility in the alpine region.
5. Health and Injuries: Ötzi's body revealed evidence of several injuries and health conditions. He had a number of broken ribs, possibly indicating a fall or accident. He also had wear-and-tear on his joints, suggesting a physically demanding lifestyle. Additionally, Ötzi had an arrow wound on his left shoulder that likely contributed to his death, as well as signs of head trauma.
6. Copper Axe: One of Ötzi's most significant possessions was a copper-bladed axe, which is one of the earliest examples of metal use in human history. This suggests a level of sophistication in his society's technology and craftsmanship.
7. Genetic Analysis: Ötzi's DNA has been extensively studied, providing insights into his ancestry and genetic traits. This analysis revealed that he had a genetic predisposition for cardiovascular disease, lactose intolerance, and a higher risk of certain autoimmune disorders.
8. Cultural and Historical Significance: Ötzi's discovery has offered a unique window into the life of an individual from the distant past. Researchers have gained valuable information about ancient diets, clothing, tools, and health conditions. Ötzi has also helped to reconstruct aspects of Copper Age society, including trade routes and cultural practices.
9. Exhibition and Research: Ötzi's mummy is preserved and displayed at the South Tyrol Museum of Archaeology in Bolzano, Italy. Researchers continue to study his remains using various advanced techniques to uncover more information about his life, death, and the world he lived in.

Overall, Ötzi the Iceman is a remarkable archaeological discovery that has provided invaluable insights into the lives of our ancient ancestors and their interactions with the environment and technology of their time.
