ISTA | Ants Signal Deadly Infection

Scientists at the Institute of Science and Technology, Austria, have found that terminally ill pupae in an ant colony emit a chemical signal that prompts worker ants to disinfect them with formic acid — a process that also brings about their death. This behaviour helps keep the colony free from infection and represents a clear example of evolved altruism with a genetic basis. Their findings are reported, open access, in Nature Communications.

One of the criticisms often levelled at evolutionary biology is that it cannot explain altruism, since individuals that sacrifice themselves for others seemingly shouldn’t survive to pass on any genes responsible for such behaviour.

This is plainly untrue. Acts of altruism are widespread in nature: male spiders and mantises are consumed by their mates, providing nutrients for developing eggs; the offspring of social spiders consume their mother, then go on to consume one another. These behaviours persist because they enhance the success of the genes involved.

The key lies in what Richard Dawkins termed the selfish gene. Contrary to creationist misrepresentations, this is not a claim that there exists a gene for selfishness. It refers instead to the way genes appear to act in their own interests. Genes promoting altruistic behaviour benefit when that behaviour increases the reproductive success of individuals carrying the same genes — typically close relatives. The sacrifice of one carrier can thereby enhance the spread of the genes responsible for the altruism.

In humans, altruism arises not only from genetic evolution but also from memetic evolution — the inheritance and adaptation of ideas, norms, and cultural expectations. Human altruism rarely requires life-or-death sacrifice; it more often involves smaller acts such as sharing resources, giving up a seat on a bus, or letting another driver go first at a junction. The advantage, at both genetic and memetic levels, is that such behaviours help build societies where cooperation is reciprocated. Altruism is ultimately an investment in a more stable, supportive environment that may benefit the genes and memes of the individuals who contribute to it.

Unintelligent Design - How The Human Genome Has Mutation-Prone Weak Spots - Incompetence, Malevolence or Evolution?

If the outcome is pre-ordained, what are all the other sperms for?

New mutation hotspot discovered in human genome | EurekAlert!

Creationists and other religious fundamentalists claim that their god deliberately fashions each human life according to a divine plan — that every individual is personally designed, even down to the genes they inherit from their parents. But this raises a perpetually unanswered question: why produce so many sperm cells, all competing to reach the egg, if the outcome is pre-ordained?

Creationists also insist that our DNA is a “code”, equivalent to a computer program that must have been created by an intelligent designer or programmer.

If that were true, we would expect the genes bestowed on each individual to be robustly designed and immutable.

However, new research by scientists at the Centre for Genomic Regulation, Barcelona, Catalunya, Spain, just published in Nature Communications, shows that this is not the case — and once again, a prediction of fundamentalist creationism has been falsified by science.

The researchers found that the human genome is especially vulnerable to mutations in the first 100 base pairs of genes, particularly during the earliest rounds of cell division in embryo development. Each division introduces mutations with the potential to cause disease, including cancer. Because these mutations do not appear in every cell of the early embryo, the resulting individual becomes a genetic mosaic, with some cells and tissues carrying certain mutations while others do not. But if the mutated cells give rise to germ cells — eggs or sperm — the mutation can be passed to the next generation, whose members will carry it in all their cells and may develop disease as a result.

Unless creationism’s designer god intended this outcome, or is incompetent, there is no coherent way to present this as the deliberate work of an intelligent designer. It is, however, entirely consistent with an unintelligent, utilitarian evolutionary process that settles for sub-optimal solutions based on a single criterion: what produces the most descendants who themselves reproduce?

Malevolent Design - How Breast Cancer is 'Designed' to Survive

The Rockefeller University » This molecular switch helps cancer cells survive harsh conditions

Researchers at The Rockefeller University's Laboratory of Biochemistry and Molecular Biology have uncovered the mechanism that enables breast cancer cells not only to withstand environmental stress, but to turn it to their advantage. They have just published their findings in Nature Chemical Biology.

For ID creationists, these findings pose yet another challenge—one typically ignored or waved away as the consequence of ‘sin’, neatly exposing the Discovery Institute’s attempt to persuade US legislators and educators that ID is a genuine scientific alternative. No real science explains inconvenient evidence by invoking fundamentalist doctrine or unevidenced forces inherited from ancient superstition.

The Rockefeller University team has shown that breast cancer cells can override a regulatory factor that normally controls gene expression. The transcription of DNA into mature messenger RNA involves the enzyme RNA polymerase II (POL II), whose activity depends on around 30 subunits. One of these, MED1, normally carries acetyl groups. Without those acetyl groups, MED1 loses its ability to regulate POL II, allowing the enzyme to transcribe genes that help cancer cells survive. Environmental stress deacetylates MED1. In essence, conditions such as low oxygen or elevated temperature—deadly to normal cells—can instead make cancer cells more resilient.

Refuting Creationism - How Butterfly Genomes Confirm Darwin's Conclusion

[Body]

1,000 butterfly and moth genomes to investigate evolution, climate change resilience, and tackle food security issues

Geneticists at the Wellcome Sanger Institute have just completed the sequencing of 1,000 European butterflies and moths. Their results are already feeding into research papers, such as that by Asia E. Hoile, Peter W. H. Holland & Peter O. Mulhair, in BMC Genomics. The Wellcome Sanger team have published their results in Trends in Ecology & Evolution

In 1858, Charles Darwin and Alfred Russel Wallace proposed the theory of evolution by natural selection, or as they described it, the origin of species by the preservation of favoured races. Darwin then elaborated on that central idea and concluded that the ‘tree of life’ would branch in ways consistent with diversification from common origins.

Creationists, on the other hand, claim all species were created by magic in their present form just a few thousand years ago, with no evolution and no common ancestry.

Darwin's Tree of Life sketch

Neither Darwin nor Wallace knew anything about DNA or genomes, or that mutations in DNA would become ‘favoured’ in particular environmental niches, driving diversification. They developed their ideas purely from the observable morphological and behavioural similarities and differences among species.

So, if the creationists are right, what should we see in these 1,000 genome sequences?

Malevolent Design - How Some Cancers Are Designed to Win - Incompetence or Malevolence?

Cancer cells dividing

Shapeshifting cancers’ masters, unmasked | Cold Spring Harbor Laboratory

Scientists led by Cold Spring Harbor Laboratory (CSHL) Professor Christopher Vakoc have uncovered a mechanism by which certain cancers manage to evade modern medical treatments: they can disguise themselves as ordinary cells from entirely different tissues, such as those of the skin. In two recent papers — one in Nature Communications and another in Cell Reports — Vakoc’s team identify the proteins that determine whether pancreatic cancer cells retain their pancreatic identity or slip into a skin-cell-like state. They also highlight a different set of proteins with a pivotal role in tuft-cell lung cancer.

Proteins, of course, are specified by genetic information, and if that information is altered, so too is the protein’s function. In the language of ID creationists, proteins are products of “complex, specified genetic information”.

This presents intelligent design creationists with a familiar problem — one they usually address, as with parasites and pathogens, by ignoring it and relying on the scientific illiteracy of their followers. If complex, specified information were genuinely evidence of an intelligent designer, then that same designer would be implicated in the origin of the proteins that maintain and diversify cancers. Their “specified information” is neither less complex nor less specific than the proteins involved in cognition, immunity, or embryonic development.

Only by refusing to define “complex specificity” in scientific terms — or to explain how it might be distinguished from information that is supposedly non-complex or non-specified — do ID advocates manage to maintain the fiction that all beneficial traits are the work of their designer, while harmful traits must arise from some other agency. This selective attribution, based entirely on subjective human preference, underscores the religious foundations of intelligent design creationism and its distance from genuine science.

The team’s findings are summarised in a Cold Spring Harbor Laboratory news release by Jen A. Miller.

The world’s oldest RNA extracted from woolly mammoth - Stockholm University

Scientists led by researchers from Stockholm University, Denmark, have just announced that they have successfully extracted RNA from 40,000-year-old mammoth remains — the oldest RNA ever obtained. This shows that not only DNA but also RNA can persist for extraordinary lengths of time under the right conditions, adding yet more to the mountain of evidence that undermines creationist claims. With preserved RNA, researchers can even reconstruct the DNA that originally served as its template, effectively giving scientists two independent avenues for recovering genetic information.

One of the joys of debunking creationism — a childish superstition when set beside the rigour of evolutionary biology — is the sheer abundance of evidence. Almost every peer-reviewed paper in biology, geology, palaeontology, cosmology, and the other natural sciences demonstrates, in one way or another, the reality of evolution and the age of the Earth, and presents verifiable results that creationism simply cannot accommodate.

Even psychology lends its weight. Not only does it support an evolutionary account of human cognition and intelligence, but it also helps explain why creationists cling so tightly to demonstrably false beliefs. For many, rejecting evidence becomes a test of loyalty or personal strength, with scientific data treated as part of a supposed conspiracy designed to shake their faith. If they can cling to their faith despite the overwhelming contrary evidence, then they must really believe it.

Adding this new discovery to the existing evidence is rather like tossing a pebble onto Mount Everest and expecting creationists to accept the mountain’s existence because a pebble lies on it. Such acceptance is impossible for the committed creationist, since that would mean yielding to the ‘evil conspiracy’ and admitting that their favourite holy book is not a perfect, divinely authored scientific text, but a compilation of Bronze Age and Early Iron Age mythology, created by people doing their best to explain a world they did not yet understand.

Creationism Refuted - Doggy Dos For Creationists

Dogs 10,000 years ago roamed with bands of humans and came in all shapes and sizes

This is the second article in The Conversation which incidentally refutes creationism and shows us why the Bible must be dismissed as a source book for science and history on the basis that, when compared to reality, it's stories are not just wrong; they're not even close.

This one deals with essentially that same subject as my last past - the evolution of all the different dog varieties since wolves were first domesticated some 11,000 years ago. Together with all the other canids that creationists insist are all dog 'kind', including several foxes, several subspecies of wolf, coyotes, jackals, and African wild dogs, the hundreds of different recognised breeds of dog could not conceivably have arisen from a single pair and the resulting genetic bottleneck just a few thousand years ago. Moreover, we are expected to believe that in that short space of time, all the canids evolved from being vegetarian (with canine teeth, meat-cutting incisors and bone-crushing molars, apparently) to being obligate carnivores.

As well as the paper that was the subject of my last blog post, this The Conversation article mentions another paper, also published in Science by palaeontologists led by Shao-Jie Zhang from the Kunming Institute of Zoology, China. This paper draws on DNA evidence from ancient Eastern Eurasian dogs.

How We Know The Bible Was Wrong - Creationists Dogged by DNA And Fossil Evidence

Sharma the Wolf

From The Girl and the Wolf,
By Bill Hounslow

Dogs 10,000 years ago roamed with bands of humans and came in all shapes and sizes

This is the first of two articles published in The Conversation concerning the origins of domestic dogs and the myriad different breeds that have been developed under human agency since wolves were first domesticated. Neither of them is good news for creationists for several reason.

Firstly, the DNA evidence points to a history much older that the simple tale origin tale in the Bible allows for - a history stretching back some 11,000 years or more to before creationists believe anything existed.

Secondly, and this is something that I have found creationists will always run away from - if God supposedly created all animals for the benefit of humans, why have we had to modify them to such an extent that in many cases they are scarcely recognisable from their wild ancestors? Did God not know what we would use them for or what designs would be best suited for different purposes?

The answer of course, is that the Bible stories are just that - stories. They were never intended to be written down and bound together in a book later declared, by people with a personal stake who needed a spurious 'God-given' authority to take control of society, to be the inerrant word of a creator god and therefore definitive history and science textbooks. Their complete misalignment with observable reality should be more than a clue that the latter is wrong.

How Science Works - Not Abandonning Evolution - Refining Our Understanding Of It

This article is best read on a laptop, desktop, or tablet

A new theory of molecular evolution | University of Michigan News

A new paper in Nature Ecology & Evolution by a research team at the University of Michigan, led by evolutionary biologist, Professor Jianzhi Zhang, comprehensively, but incidentally, refutes several common creationist claims — such as that mainstream biologists are abandoning evolution because it supposedly cannot explain the evidence, that all mutations are harmful, so cannot underpin evolution, and that scientists are prevented from publishing findings that challenge orthodoxy.

The study examines a key assumption of the Neutral Theory of Molecular Evolution — namely that most amino-acid substitutions are neutral (neither beneficial nor strongly deleterious) and fix by drift rather than selection. The authors report experimental data showing that in mutational-scanning assays of over 12,000 amino-acid-altering mutations across 24 genes, >1 % of mutations were beneficial, implying a far higher beneficial-mutation rate than is conventionally assumed.

To reconcile that finding with the fact that comparative genomic data appear consistent with many substitutions being neutral, Zhang’s team propose a new model — “adaptive tracking with antagonistic pleiotropy” — in which beneficial mutations are frequently environment-specific, and when the environment changes the same mutation may become deleterious, hence failing to fix. In this way, although beneficial mutations are common, they rarely reach fixation when environments shift, and substitution patterns can appear neutral.

The paper operates fully within the framework of evolutionary theory by natural selection: it does not challenge evolution itself, but refines a subsidiary theoretical model about molecular changes. Thus, it strengthens the broader evolutionary paradigm rather than undermines it.

Creationism Refuted - Neanderthals Didn't Disappear - They Became Us

A simple analytical model for Neanderthal disappearance due to genetic dilution by recurrent small-scale immigrations of modern humans | Scientific Reports

One of the enduring myths cherished by creationists is that humans appeared suddenly, as a distinct and immutable species, untouched by the messy processes of evolution. Yet study after study continues to reveal just how fluid and interconnected the human story really is. The latest comes from three researchers - Andrea Amadei, Giulia Lin, and Simone Fattorini - who have just published a fascinating analytical model in Scientific Reports explaining how the Neanderthals did not simply “vanish,” but were gradually absorbed into the expanding population of early modern humans.

This idea is not new, as I have reported before in this blog here and here, but what is new is this analytical model that shows how easily it happened. The model shows that repeated, small-scale migrations of Homo sapiens into Neanderthal territories would have resulted in gradual genetic dilution over time, without any need for violent extermination or sudden extinction events. Their DNA lives on in our genomes today — in Europeans, Asians, and other non-African populations — a genetic signature of our shared ancestry.

This finding adds yet another layer to the mounting evidence that humanity is not the product of divine design without ancestry but of evolutionary blending and adaptation. The neat, separate categories that creationists like to imagine simply never existed. Instead, what we see is a continuum of populations interacting, interbreeding, and shaping one another’s evolutionary fate. Rather than distinct “kinds,” humans and Neanderthals were part of a dynamic, interconnected lineage shaped by migration and time — the very processes that creationist dogma denies.

Far from the simplistic tale of a single miraculous creation, the history of our species is one of mixture, movement, and gradual transformation — precisely what evolution predicts, and precisely what the fossil and genetic evidence confirms.

Deciphering the mechanisms of genome size evolution - Current events - University of Barcelona

For years, creationists have confidently assured anyone who’ll listen that evolution can’t possibly work, because losing genetic material is always disastrous — rather like claiming a book can’t be edited without collapsing into meaningless gibberish. Yet nature has an unhelpful habit of ignoring such pronouncements and getting on with things regardless. And now, a tiny spider living quietly in the Canary Islands has delivered another inconvenient data point: it’s been shedding DNA at a remarkable rate, and doing perfectly well in the process.

Researchers led by Julio Rozas and Sara Guirao, from the Faculty of Biology and the Biodiversity Research Institute (IRBio) at the University of Barcelona, have shown that a spider endemic to the Canary Islands has lost almost half its genome in only a few million years.

The spider, Dysdera tilosensis, is a close relative of the mainland species D. catalonica and the familiar British woodlouse-hunter, D. crocata, yet is morphologically almost identical to both.

The findings have been published in the journal Molecular Biology & Evolution.

This discovery runs counter to a general pattern in evolutionary biology, in which adaptation to oceanic island environments often involves increases in genome size. Rather than undermining evolution, this unexpected result enriches the scientific debate over how and why genome size changes during evolution.

It also raises awkward questions for creationist dogma. Why would an intelligent designer equip spiders with almost twice as much genetic material as they actually need? And how would one distinguish such closely related species or show a transition from one to the other in the fossil record, if genome size — the key difference — leaves no trace in fossils?

Refuting Creationism - Ancient Teeth Show Mixed Origins Of A Transitional Hominin - 2 Million Years Before 'Creation Week'

Paranthropus robustus

New clues from 2 million-year-old tooth enamel tell us more about an ancient relative of humans

Human evolution isn’t a tidy staircase; it’s a branching, tangled tree full of transitional forms. And now, cutting-edge protein analysis from two-million-year-old teeth has revealed that Paranthropus robustus — one of our distant cousins — carried mixed ancestry, adding powerful new evidence to the evolutionary story creationists work so hard to deny.

If there is anything guaranteed to send a creationist into a fit of denial — desperately trying to redefine basic terms such as “transitional”, “species”, and “evolution”, and, as a last resort, claiming palaeontologists must have faked the evidence — it is the discovery of a transitional species in human evolutionary history.

But the hominin fossil record, like the evolutionary record for most living species, is absolutely packed with transitional forms. In fact, there are so many in human palaeontology that it can be difficult to single out one that is clearly more ‘transitional’ than the rest, because they form a fairly smooth continuum from the australopiths through to the genus Homo, just as we would expect of a slow process unfolding over tens of thousands or millions of years.

However, one species, Paranthropus robustus, stands out for its mosaic of features consistent with a lineage intermediate between the common ancestor of chimpanzees and hominins and the australopiths that followed.

And this mosaic has now been expanded to include genetic-level evidence, thanks to advances in palaeoproteomics. Proteins can persist far longer than DNA, yet they retain a direct correspondence to DNA via RNA, which encodes their amino-acid sequences. Once ancient proteins have been recovered and analysed, researchers can work backwards to reconstruct the RNA, and therefore the DNA, that produced them.

Using proteins extracted from the tooth enamel of four P. robustus fossils, researchers led by the University of Copenhagen have shown that these individuals themselves had mixed ancestry — indicating interbreeding with contemporaneous relatives, just as we now know happened among later hominin species, and almost certainly among the australopiths too.

Refuting Creationism - The Human Skull Evolved Fastest of All the Apes

Great Apes

Gómez-Robles Aida, et al. (2025)

Humans evolved fastest amongst the apes | UCL News - UCL – University College London

A newly published paper in Proceedings of the Royal Society B by researchers from University College London (UCL) shows that the human skull evolved relatively rapidly compared to that of other apes. The evolutionary changes involve modifications in the size and shape of the facial and cranial bones.

This serves as a reminder of just how artificial and functionally useless the creationist concept of a “kind” is. It should also show creationists the fallacy of the frequent claim that biologists are abandoning the Theory of Evolution, since this paper discusses the results of evolution, not some infantile notion of magical intervention by an unevidenced supernatural entity.

Creationists are quite content to regard all cats—from domestic tabbies to tigers—as belonging to the same “kind”, even though the main difference between them lies in the size of their skeletons. Yet they balk at the idea that humans and the great apes could belong to the same “kind”, despite the fact that the key distinctions between us and them are also differences in size and proportion—most notably in the bones of the skull.

But then, “kind” is precisely the sort of term creationists favour because it has no fixed definition and can be expanded or contracted to suit whatever argument they are trying to make. The only consistent rule seems to be that whatever constitutes a “kind”, it must always exclude humans. This sometimes leads to the absurdity of defining an “animal kind” and a separate “human kind”.

The UCL team suggest that the rapid evolution of the human skull can be explained by the considerable advantage conferred by a larger brain and advanced cognitive abilities.

Our complex cognition allows us to communicate abstract ideas through both words and gestures—what we call “body language”—much of which depends on facial expression. A flat, forward-facing face enhances our ability to convey and interpret these subtle cues. As social animals, we identify acquaintances and strangers by their faces; we watch the faces of those who speak to us; and we instinctively read emotions such as pleasure, anger, confusion, or distress in their expressions.

In short, it is our large brain and expressive face that make us human — not the addition of new organs or limbs, as creationists often insist marks a change above the genus level, but rather differences in the size and shape of the bones of the skull. Given the close similarity of our genomes to those of other apes, these differences arise not from the amount of genetic information, but from the way that information is regulated during embryonic development.

Refuting Evolution - Allopatric Evolution, Just as The Theory of Evolution Predicts

Natural Japanese and Taiwanese Hinoki Cypresses Genetically Differentiated 1 Million Years Ago | Research News - University of Tsukuba

Japanese plant geneticists, led by scientists from University of Tsukuba, have shown that the Japanese and Taiwanese Hinoki cypresses began to diverge around one million years ago, following the destruction of a land bridge that once connected Taiwan to the Japanese archipelago.

This is a textbook example of allopatric speciation, in which an isolated population diverges from its parent population through a combination of founder effects, genetic drift, and natural selection in response to different environmental pressures.

The now-vanished land bridge once linked Taiwan to the southern Japanese island of Kyushu. Its remnants form the Ryukyu Arc — a chain of small islands marking the south-eastern boundary of the South China Sea.

Faced with such clear evidence of speciation, creationists typically resort to a familiar tactic: redefining evolution into a straw man. They insist that “evolution” means one species turning in a single event into something utterly unrelated — for instance, that these cypresses should transform into daisies, cabbages, mammals, or birds. If such an absurd event ever occurred, it would in fact falsify evolutionary theory and throw the entire fields of biology and taxonomy into chaos. This is the standard creationist tactic on social media: misrepresent science, then demand that science defend the misrepresentation, and claim victory when it doesn’t.

The reality remains, however, that the divergence of these related species of cypress — and the fact that this divergence can be correlated precisely with geological change — stands as powerful evidence for Darwinian evolution. Charles Darwin knew nothing of genes, alleles, or genetic drift, yet his description of descent with modification through inherited traits is elegantly confirmed here by modern genetics and biogeography. The genus Chamaecyparis — commonly known as the false cypresses — is an evolutionarily interesting group of conifers in the cypress family Cupressaceae. Their distribution and divergence provide a good illustration of how geological change, climate oscillations, and geographic isolation have shaped the evolution of temperate conifers.

Wheat monoculture - but it could have been better designed!

Scientists Discover a Gene that Could Triple Wheat Production | College of Agriculture & Natural Resources at UMD

News that a single mutant gene could triple wheat yields raises some uncomfortable questions for Bible-literalist creationists, and indeed for anyone who believes their god created the Earth and all life on it exclusively for humans — its supposed favoured species, for whom “all of creation” was made.

This belief has profoundly shaped Western attitudes towards the planet and its resources. One consequence of this selfish worldview has been the destruction of vast areas of the Earth, its ecosystems, and the countless species that depend on them. In the relentless search for mineral wealth, cropland, and grazing land, humans have transformed immense regions into effective monocultures which, to anything not adapted to those particular crops, might as well be deserts. Moreover, the same belief — coupled with the idea that brown and black people were inferior to whites and therefore “created” to serve Europeans — helped justify imperialism and the transatlantic slave trade.

One question that creationists, in my experience, consistently shy away from is this: if an omniscient god truly created our domestic animals for our use, why have we almost always had to modify them through selective breeding to make them more useful? It’s as though this god didn’t actually know what we would need or how we would use these animals. Which leads to the obvious follow-up question: why didn’t this supposedly omniscient being create ideal domestic plants and crops in the first place?

Malevolent Design - How Creationism's 'Designer' Favoured The Naked Mole Rat

DNA repair mechanisms help explain why naked mole-rats live a long life

News that scientists have discovered what enables the naked mole-rat to live for up to 37 years — around ten times longer than relatives of a similar size — raises a troublesome question for creationists. The findings were reported recently in Science by a team of researchers from the Shanghai Key Laboratory of Maternal Fetal Medicine.

Creationists like to flatter themselves with the notion that they are the favoured creation of their putative designer god and the ultimate expression of design perfection. So, when evidence emerges of other species surpassing humans in some way — bats with more robust immune systems, elephants and sharks being almost completely immune to cancers, peregrine falcons with far superior vision — it is typically ignored, met with incredulity, or dismissed as an ineffable mystery and part of some divine plan which in no way diminished the unique position of humans in the grand scheme.

Now, to add to their woes, comes the discovery that the secret of the naked mole-rat’s extraordinary longevity may be traced to changes in just four amino acids. This alone undermines creationist claims that mutations are always harmful and incapable of generating new genetic information.

Fungi set the stage for life on land hundreds of millions of years earlier than thought | Okinawa Institute of Science and Technology OIST

In that vast expanse of pre-‘Creation Week’ history, when 99.9975% of Earth’s story had already unfolded, a pivotal event occurred that would set the planet on a path towards the astonishing diversity of life we see today. According to researchers led by scientists at the Okinawa Institute of Science and Technology, Japan, that turning point was the evolution of multicellular fungi.

Unlike animals and plants, in which multicellularity appears to have arisen only once, fungi seem to have achieved it independently on at least five separate occasions, between 1.4 and 0.9 billion years ago.

This innovation allowed fungi to colonise land and begin transforming bare rock and rock debris into soil. That process, in turn, created the conditions that later enabled plants to establish themselves on land.

In addition to shedding light on how multicellularity evolved in fungi — a process that involved horizontal gene transfer — this research significantly extends the known timeline of fungal evolution, pushing it back by hundreds of millions of years.

Of course, the authors of Genesis, unaware of the distinction between plants and fungi and apparently thinking all plants were angiosperms, made no mention of fungi at all. Their myth betrays no understanding that plants are living organisms or that green plants depend on sunlight for photosynthesis, since it describes them as being created the day before the sun (Genesis 1:15-17). It names only angiosperms while ignoring ferns, mosses, and algae (Genesis 1:11-12), and later claims that “every living substance” outside the Ark was destroyed (Genesis 7:4), as though plants, like rocks, would somehow have survived unscathed, to provide food for the animals afterwards, despite no mention of their preservation during the flood genocide.

Science, as ever, tells a very different story — one based not on gap-filling tales but on evidence written in fungal DNA and preserved in the fossil record. It is a story of awe and wonder, not at the supposed magical powers of an imagined creator, but at the relentless processes of evolution: variation, natural selection, and the exploitation of opportunity, producing the extraordinary biodiversity we see today.

Ancient DNA reveals the population interactions and a Neolithic patrilineal community in Northern Yangtze Region | Nature Communications

The bad news for creationists continues unabated - because science continues unabated to reveal the truth.

Creationists like to insist that the Bible’s tales of creation and Noah’s flood are real history, not myth. But once again, science has delivered a devastating blow to that fantasy. A new open access paper in Nature Communications reports the DNA of 58 individuals from the Baligang archaeological site in central China, spanning from the Middle Neolithic to the Late Bronze Age (6,500 BP - 2,500 BP). Far from supporting the idea of a world repopulated just a few thousand years ago by Noah’s family, the evidence shows continuous human settlement, migration, and cultural development stretching back thousands of years before, during and after the supposed date of the Biblical flood - about 4,000 years BP.

The genetics reveal a population that was anything but “reset.” Northern and southern East Asian groups repeatedly mixed at Baligang, leaving detectable signatures of long-term population movement and exchange. Around 4,200 years ago, southern ancestry became especially prominent, signalling migration into the region. Burial evidence adds further depth: the males were closely related along the paternal line, while the females carried diverse maternal lineages—clear evidence of patrilineal clans drawing in women from outside communities. This is a picture of a complex, interconnected society developing steadily over time.

Landmark Discovery Reveals How Chromosomes Are Passed From One Generation to the Next | UC Davis

This article continues my series exploring the many ways in which the human body demonstrates unintelligent design. Far from being the perfect handiwork of a benevolent creator, our anatomy and physiology are full of flaws, inefficiencies, and dangerous vulnerabilities. Each of these makes sense in light of evolution by natural selection—an opportunistic, short-term process that tinkers with existing structures—but they make no sense at all if we are supposed to be the product of an all-wise designer.

Creationists often argue from a position of ignorant incredulity, claiming that complexity implies intelligent design, when in fact the opposite is true. The hallmark of good, intelligent design is simplicity, for two very simple reasons: first, simple things are easier to construct and require fewer resources; and second, simple structures and processes have fewer potential points of failure, making them more reliable.

In short: complexity is evidence against intelligent design and in favour of a mindless, utilitarian, natural process such as evolution.

In addition to being minimally complex, another characteristic we would expect of something designed by an omniscient, maximally intelligent, and benevolent designer is that the process should work perfectly, every time, without fail.

The problem for creationists is that their favourite example of supposed intelligent design — the human body — is riddled with complexity in both its structures and processes. This complexity provides countless examples of systems that fail to perform adequately, or fail altogether, with varying frequency. Many failures occur in the layers of complexity needed to control or compensate for the inadequacies of other systems, and when those compensatory mechanisms themselves fail, the result can be a cascade of dysfunctions or processes running out of control. The consequences manifest as diseases, defects, and disabilities — hardly the work of an all-wise designer.

They are, however, exactly what we would expect from a mindless, utilitarian process like evolution, which prioritises short-term survival and reproduction, selecting only what is better — sometimes only marginally better — than what preceded it, rather than seeking optimal solutions. I have catalogued many such suboptimal compromises in the anatomy and physiology of the human body, and the problems that arise from them, in my book, The Body of Evidence: How the Human Body Refutes Intelligent Design, one of my Unintelligent Design series.

Just yesterday, I wrote about research suggesting that autism may be a by-product of the rapid evolution of intelligence in humans. Now we have another striking example of extreme biological complexity which, when it goes wrong, can have catastrophic consequences: the production of eggs in women and sperm cells in men.

Refuting Creationism - How Autism May Be The Result Of Compromise In The Evolution Of Human Intelligence

If the human genome had been intelligently designed by an omniscient, omnibenevolent, omnipotent supernatural deity, as creationists insist, it should be perfect and free from defects of any sort. In fact, it is difficult to see why there would be any variance in such an intelligently designed genome, let alone variance that causes genetic defects—unless those were intentionally included by the designer, who then cannot reasonably be described as omnibenevolent or omniscient.

If, however, the human genome is the product of hundreds of millions of years of gradual evolutionary processes — processes that prioritise survival and reproduction, with all the sub-optimal compromises that a utilitarian form of ‘design’ entails — then variance and defects are exactly what we would expect.

Creationists traditionally ignore questions about the origin of variance in a supposedly ‘perfect’ intelligently designed genome. The existence of genetic defects is usually explained away by resorting to Bible-literalist mythology about ‘The Fall’ — an abandonment of the Discovery Institute’s Wedge Strategy, which seeks to present creationism as real science rather than a fundamentalist religion dressed in a lab coat. News that autism may in fact be a by-product of the evolution of intelligence in humans will therefore be an even greater problem for creationists, who insist that our high intelligence sets us apart as the special creation of a perfect god.

Ironically, as well as possessing high intelligence, humans — unlike any other primates — also have autism and schizophrenia. It is this correlation that provides a clue to their shared evolutionary origins.

My book, The Body of Evidence: How the Human Body Refutes Intelligent Design, lists lots of examples of how the human body is the result of these sub-optimal evolutionary compromises with all the problems that has produced. This example is just another instance and more evidence of the lack of intelligence in the process.
