Abiogenesis News - The Genes That Predate Life

Scientists describe a window into evolution before the tree of life | Oberlin College and Conservatory | EurekAlert!

In a paper published recently in the journal Cell Genomics, scientists Aaron Goldman (Oberlin College), Greg Fournier (MIT), and Betül Kaçar (University of Wisconsin–Madison) describe how they were able to study evolutionary history even before the last universal common ancestor of all living things (LUCA) emerged, and discovered that some of the genes associated with LUCA may in fact predate LUCA itself.

Creationists determined to misrepresent the process of abiogenesis often present it as a ridiculous parody in which a fully complex cell is supposed to have spontaneously assembled out of inorganic atoms and molecules. This straw-man caricature is far easier to attack than what science actually proposes: that the first population of self-replicating proto-cells arose through gradual chemical and evolutionary processes within a large and diverse population.

Within such a population, variation would inevitably occur, and whatever produced the most copies of itself would come to dominate. One of the earliest characteristics to emerge would have been rapid replication, because in a vast population with generation times measured in minutes, even “million-to-one” mutations are not rare events — they occur thousands of times a day. Under such conditions, what creationists portray as wildly improbable becomes not only plausible, but effectively inevitable over time.

Several independent evolutionary pathways could also have developed in parallel: RNA molecules coding for particular enzymes, ribosomes assembling from self-catalysing RNA, and primitive membranes forming across which chemical energy gradients could arise. Only once these components were already present could they come together within an enclosing membrane to form the first true prokaryotic cells.

The research team led by Aaron Goldman has now developed a method for determining which genes were likely present in LUCA, and which must already have been available to be incorporated when LUCA first emerged. In other words, some genes appear to predate LUCA itself, pushing parts of evolutionary history even deeper into the pre-cellular past.

What Was LUCA — and What Came Before It? The Last Universal Common Ancestor (LUCA) is often misunderstood, especially by creationists who portray it as the very first living organism. In reality, LUCA was not the origin of life, nor the first cell, nor some single creature that suddenly appeared fully formed.

LUCA is simply the most recent population of organisms from which all life alive today ultimately descends — bacteria, archaea, and eukaryotes alike. Crucially, LUCA already possessed a level of biochemical sophistication. Most researchers agree it likely had:

• a genetic code based on RNA and DNA
• ribosomes capable of translating RNA into proteins
• enzymes for metabolism and replication
• membrane structures maintaining internal chemistry
• the ability to exploit chemical energy gradients

This means LUCA could not have been the beginning of life. Instead, it must have been the product of a long evolutionary history that preceded it.

Pre-LUCA Evolution: A World of Competing Proto-Life

Before LUCA, early Earth was almost certainly home to a diverse population of simpler self-replicating systems — sometimes called proto-cells or pre-cellular life. These were not fully modern organisms, but chemical systems capable of reproduction, variation, and selection.

Rather than a single miraculous event, abiogenesis is best understood as an extended evolutionary process in which:

• self-replicating molecules competed for resources
• advantageous variants spread through populations
• metabolic pathways evolved gradually
• membranes formed to enclose and stabilise reactions
• genetic and protein machinery became increasingly integrated

LUCA represents the point at which one lineage became the common ancestor of everything that survived, not the moment life began.

Genes Older Than LUCA

What makes the new research so significant is the finding that some genes associated with LUCA appear to be even older — suggesting that early evolutionary innovations were already circulating in the pre-LUCA world and later became incorporated into the first universal ancestor.

This is exactly what evolutionary theory predicts: life did not begin with a fully formed cell, but with populations of evolving systems, long before anything resembling modern biology existed.

Their methodology is explained further in a press release from Oberlin College, via EurekAlert!.

Refuting Creationism - Bonobos Can Imagine Things Detached From Reality

Apes share human ability to imagine | Hub

A paper published recently in Science should give creationists something to think about. It shows how our close relatives, the bonobos, can imagine things completely detached from physical reality — rather like children playing games of pretend, or creationists pretending they are leading experts on biology and understand the subject better than the actual experts.

In this study, two researchers from Johns Hopkins University demonstrate that bonobos can engage in imaginative “pretend play”, an ability long assumed to be uniquely human. In doing so, they dismantle yet another supposed human-exclusive trait that creationists cite as evidence of special creation.

In one experiment with a captive bonobo, Kanzi — a 43-year-old individual living at Ape Initiative — a researcher pretended to pour juice from an empty jug into a transparent empty cup, and then pour it again into a second empty cup. When asked, “Where is the juice?”, Kanzi correctly identified the second cup.

In a similar experiment, an imaginary grape was taken from an empty bowl and placed into an empty jar. When asked, “Where is the grape?”, Kanzi again correctly pointed to the jar.

These experiments show that Kanzi was able to imagine and successfully track the movement of invisible, non-existent objects — something human children can typically do by the age of about two.

We have another example today of how the evidence written into the fossil record — which creationists insist either does not exist, or is at best a lie forged to deceive us — stubbornly refuses to conform to creationist requirements. Instead, it continues to tell the only story it can: of life evolving slowly over deep time on a planet that is billions of years old.

The latest example comes from a paper published in Nature Ecology and Evolution by researchers from the Field Museum of Natural History in Chicago, Carleton University in Ottawa, Ontario, Canada and the Smithsonian Museum. The study was co-led by Arjan Mann, assistant curator of fossil fishes and early tetrapods at the Field Museum.

The paper presents evidence of the earliest known herbivorous vertebrate — dating to some 307 million years before creationists believe the Earth was created. Once again, this highlights the fundamental problem creationists face when they begin with a dogmatic belief that the Earth is only a few thousand years old because a handful of Bronze Age pastoralists said so. Having declared in advance that there has been no significant evolution, only minor variation within “kinds”, they are then forced to twist and contort the real-world evidence in a futile attempt to shoehorn it into their absurdly compressed timescale.

The animal, named Tyrannoroter heberti by the researchers, evolved over the tens of millions of years since the first vertebrates transitioned from lobe-finned fish to terrestrial tetrapods around 375 million years ago — perhaps to escape aquatic predators, or to exploit the invertebrate prey that had already colonised the land. Plants, meanwhile, which had begun spreading onto land some 475 million years ago, had also been evolving, and by this time were well established as ferns, horsetails, and other tough early vegetation.

Tyrannoroter heberti, known so far from a single skull, was probably among the largest terrestrial animals alive at the time, reaching around a foot in length — roughly the size of an American football — based on the proportions of close relatives. The fossil was recovered from shoreline cliffs in Cape Breton, Nova Scotia, Canada.

It is thought to represent a stem amniote: part of the lineage of vertebrates that evolved the ability to lay eggs away from water, unlike amphibians which must still return to water to reproduce. This group ultimately gave rise to reptiles, birds, and mammals — in other words, to almost the entire later terrestrial vertebrate world, including ourselves.

Creationism Refuted - Why We Need Our Gut Microbiome To Keep Us Healthy

What gut bacteria like

An open access paper in Proceedings of the National Academy of Sciences of the USA (PNAS) is a stunning example of the ludicrous complexity evolution has produced — the exact antithesis of what an intelligent designer would create, if such a designer were anything more than grossly incompetent. As I explain in my book, The Unintelligent Designer: Refuting The Intelligent Design Hoax, and as I have pointed out repeatedly on this blog, the hallmark of intelligent design should be minimal complexity and maximal efficiency. And yet what we find in humans — and in just about every other bilaterian animal with a gut — is a vast, intricate symbiotic microbiome supplying functions that could far more simply have been provided directly, with even a little forethought on the part of any competent designer.

Instead, in the sort of convoluted complexity that creationists like to attribute to their putative designer god, but which is in reality a hallmark of evolved systems, we see yet another example of a biological arrangement that betrays not intelligence, but its absence.

The paper, by an international team led by Professor Victor Sourjik and colleagues from the Max Planck Institute for Terrestrial Microbiology, the University of Ohio, and Philipps-University Marburg, describes how an interdependent gut microbiome helps to keep both the microorganisms and their host healthy. They show that this complex and dynamic community is governed by countless chemical interactions — not only among the microorganisms themselves, but also between microbes and host tissues. The perception of nutrients and signalling molecules by gut bacteria is therefore crucial in maintaining these relationships.

One key role of this microbiome is in deterring and combating pathological species which would otherwise find the gut — with its warmth and steady supply of pre-digested nutrients — an ideal environment to colonise. This must have been a problem even for the earliest animals with a digestive tract: a vulnerability effectively built into the body plan. The solution, in the form of beneficial commensal organisms, is therefore probably as old as the first tube-like bilaterians themselves.

The problem the human gut faces in this respect can be gauged from the fact that some studies have shown that 50-55% or more of the dry weight of human faces is bacteria, dead and alive[1] , with populations of bacteria in the order of 10¹¹ bacteria per gram![2] Imagine then the opportunities this presents to a potentially pathological bacteria with a generation time in minutes. With a population exploding exponentially, the potential to overwhelm the host in a few days is enormous. This is the scale of the problem, and of the selection pressure to overcome it, that has produced this massively complex solution, because it wasn't solved in the initial 'design' stage.

Since it worked well enough, there has been no evolutionary pressure to replace it with a less vulnerable gut, or one better equipped to cope with infection without relying on an entire ecosystem of different microorganisms to maintain health. In other words, what we have today is the result of more than half a billion years of evolutionary history since this basic body plan first emerged in the Cambrian.

Malevolent Design - How Ovarian Cancer Looks Intelligently Designed to Spread Rapidly

Creationism's intelligent designer at work

Scientists now know why ovarian cancer spreads so rapidly in the abdomen | Nagoya University

If intelligent design advocates were honest enough to follow the logic of their own arguments and apply it consistently to the real world, they ought to be acutely embarrassed by the deity they are presenting to the public. Their putative designer god, judged by the evidence they themselves cite, looks less like a benevolent engineer and more like the author of suffering, disease, and death.

That uncomfortable reality is illustrated by yet another research paper showing that pain and mortality can be the direct result of the very things ID proponents celebrate as hallmarks of design: irreducible complexity and “complex specified information”.

This latest example comes from scientists at Nagoya University, Japan, who have shown how ovarian cancer forms an alliance with healthy cells that enables it to spread rapidly to other organs in the abdomen. Their paper has just been published in Science Advances.

As regular readers will be aware, a recurring theme of this blog is that ID advocates conspicuously ignore the vast number of examples from parasitology, oncology, and genetics where the very evidence they cite for an intelligent designer applies just as readily to diseases caused by parasites, pathogens, and genetic malfunctions. Applying ID’s own logic, these are not signs of benevolent craftsmanship but evidence of something far darker — a malevolent intent behind the supposed designer.

The paper in Science Advances is yet another case in point, and doubtless there will be many more soon.

The authors discovered that ovarian cancer cells gather clusters of mesothelial cells from the peritoneum and form hybrid spheres. These protect the cancer cells, help them invade other organs, and create a pathway for metastasis throughout the abdomen. Worse still, these hybrid spheres resist chemotherapy more effectively than cancer cells alone.

If something this complex resulted in something beneficial for humans, Discovery Institute fellows Michael J. Behe and William A. Dembski would doubtless have produced one or more books about it, written magazine articles, and embarked on television tours explaining how the finding devastates “Darwinism” and constitutes scientific proof of an intelligent designer — leaving their audiences in no doubt that the locally favoured god is the only entity capable of producing such complexity.

As it is, we can expect only a deafening silence from the Discovery Institute, while their hapless supporters cast about for a fundamentalist religious excuse such as “the Fall”, or perhaps invoke some other evil agent — anything, in fact, except the god of the Bible, who is apparently only credited with designing good things.

Christian Misogyny - How Christians Abused Poor Women in Mediaeval Europe - And Would Like to Again

A poor woman forced to abandon her baby at a foundling hospital

The Christian nationalists’ 'Golden Age'.

How reproductive injustice in early modern Europe could mirror that of today | EurekAlert!

A paper just published in The Journal of Modern History by Erin Maglaque of Durham University, UK, should serve as a warning to anyone tempted to believe the Christian Church ought to have its former privileged position in society restored. It is especially relevant to women — particularly women in the USA — where liberal values are under sustained attack and far-right Christian white supremacists are gaining increasing influence within the Republican Party, with the arch-misogynist Donald Trump back in the White House, posturing (unconvincingly) as a devout fundamentalist Christian.

The paper details a history of institutionalised abuse of poor women and the denial of their reproductive freedom. The resulting “foundling hospitals” — ostensibly established as places where poor, unmarried mothers could abandon their babies in the belief they would be safe and cared for — in practice often functioned as instruments of population control. They encouraged desperate mothers to surrender their children, only for those infants to die in appalling numbers, with mortality rates as high as 91.5%.

The Middle Ages in Europe were a time when the Christian Church dominated public life; when governments ruled the people not for the people, but for the Church. It was a period of strict social hierarchy, with the poor at the bottom, and poor women especially occupying the lowest tier of society, with little or no freedom — a level of enforced female subservience that would be the envy of any Taliban purist.

It is also the era seen by many fundamentalist Christians — especially those of the American far right — as a “golden age” to which they aspire to return the United States, and ultimately the rest of the world: a time when self-appointed clerics legislated for everyone else, and women were expected to “know their place.”

It is, of course, in service of this ambition that right-wing organisations such as the Discovery Institute were established by fundamentalist Christians, with the express aim of promoting an unelected Christian theocracy in the USA (see the Wedge Strategy). Their vision entails imposing Levitical-style laws on the population — laws that would mandate the death penalty for countless American women for not being virgins on their wedding night (Deuteronomy 22:13–21), and laws that would require a rapist to purchase his victim from her father and bind her to a lifetime of sexual slavery and domestic servitude (Deuteronomy 22:28–29).

It is against this backdrop that the reversal of Roe v. Wade and the various state-level attempts to deny family planning services should be understood. Women are losing the right to bodily autonomy and sexual freedom, just as they did under the Church-dominated order of medieval Europe.

Refuting Creationism - Conflict and Ritual Killings In Europe - Evidence That Wouldn't Be There If The Bible Tales Were True

Locations of the massacres.

From: Teresa Fernández-Crespo et al. (2025).

New research reconstructs the identity of victims from one of the earliest victory celebrations in Europe. | School of Archaeology

Of course — and this is a really strong draft already: clear, punchy, and very much in your usual style. I’ve just smoothed the grammar, corrected spelling, tightened a few phrases, and made the flow a little more polished while keeping your voice intact. Evidence revealed in a paper just published in Science Advances tells a grim story of ritualised killings in Europe about 6,000 years ago. The paper is the work of a team led by Dr Teresa Fernández-Crespo of the University of Valladolid, a Research Associate at Oxford’s School of Archaeology, together with Professor Rick J. Schulting of Oxford University. The killings appear to have been carried out as a victory celebration or demonstration of power, and they speak of conflict and struggles for regional dominance between rival Neolithic groups.

Two things about this research should trouble creationists who cling to patently absurd beliefs despite the vast array of evidence showing them to be wrong.

Firstly, this ritual slaughter took place at a time when, according to the biblical narrative, there would supposedly have been too few people on the planet to form rival groups competing for power and territory in Europe.

Secondly, none of this evidence ought to exist at all if the genocidal Flood described in Genesis had really occurred just a few thousand years ago, because it would either have been swept away entirely or, at best, buried beneath a thick layer of flood-deposited silt containing the fossils of all the dead animals and plants such a catastrophe would have produced.

The isotopic analysis of the remains tells a story of conflict on two levels: rivalry between local groups, in which severed left arms were collected as war trophies, and conflict with outsiders, prisoners from whom were ritually slaughtered in grim victory celebrations.

AI Is Good But Far From Perfect - Learning From Neanderthals

This is an AI generated image created with DALL-E 3 that was included in this research study. Its prompt described typical activities, setting, attire and tools but did not request scientific accuracy.

New study uses Neanderthals to demonstrate gap in generative AI, scholarly knowledge - UMaine News - The University of Maine

I have been using AI now for a couple of years to do research quickly to summarise scientific papers and press releases and to edit drafts to correct typos, spelling and grammatical errors and especially to generate images and illustrations. And I have to say, I think it's worth every penny of the subscription fee. However, it does get things wrong sometimes and I've frequently corrected some information or asked it to look again at an image.

Now researchers, Assistant Professor Matthew Magnani of the University of Maine, USA and Professor Jon Clindaniel of the University of Chicago, USA, have used what we know of Neanderthals to demonstrate the gap between AI-generated images and scholarly knowledge of them. The gap can widen or narrow depending on the prompt AI is given. For example, requesting scientific accuracy will produce better results than not asking for it. One of the problems the study highlights is that a great deal of scientific research is inaccessible due to copyright restrictions, before open access began to be widely used in about 2000.

Generative artificial intelligence is often marketed as a kind of universal expert — a machine that can instantly reconstruct the past, summarise scholarship, and conjure convincing images of worlds long gone. But a new study from the University of Maine demonstrates that, when it comes to archaeology and human evolution, the reality is rather less impressive. Far from reflecting the current scientific understanding of our extinct relatives, today’s most popular AI systems often reproduce something closer to the stereotypes and misconceptions of decades ago.

The researchers tested widely used generative tools, including ChatGPT and the image generator DALL-E, by asking them to describe and depict Neanderthals. What they found was striking: even when explicitly prompted for scientifically accurate, expert-level reconstructions, the outputs frequently resembled outdated mid-twentieth-century portrayals — apelike brutes, crude caricatures, and simplistic narratives that modern archaeology has long since abandoned. In effect, the AI was not drawing on the cutting edge of scholarship, but on the cultural sediment of older popular ideas.

The accompanying paper, published in Advances in Archaeological Practice, makes the deeper point that generative AI does not “know” the past in any meaningful sense. It assembles plausible-sounding and plausible-looking content from patterns in its training data — and much of that data reflects what is easily available online, not what is most accurate in the academic literature. The result is a sobering reminder that AI can be a powerful tool, but without careful expert guidance it is just as capable of reinforcing obsolete narratives as it is of illuminating the truth.

Refuting Creationistm - An Evolutionary Trap That No Intelligent Designer Would Blunder Into

Sceptobius beetles in an ant colony

The evolutionary trap that keeps rove beetles alive

A new study reported in Cell describes an extraordinary example of evolutionary adaptation unfolding right under our noses — and it will make uncomfortable reading for anyone still clinging to the creationist fantasy that living systems were neatly “designed” in their present form a few thousand years ago.

Researchers from the Division of Biology and Biological Engineering, California Institute of Technology, CA. USA, investigating the symbiotic relationship between certain rove beetles and their ant hosts have shown how these beetles have evolved the ability to infiltrate ant colonies by chemically disguising themselves as ants. Far from being “created” to live harmoniously together, this is an evolutionary arms-race in miniature: ants have evolved sophisticated chemical recognition systems to detect intruders, while the beetles have evolved equally sophisticated counter-measures to bypass those defences.

And the details are exactly the sort of thing intelligent design advocates never seem to anticipate. The beetles do not simply possess some magical, pre-installed “ant colony access” trait. Instead, evolution has shaped them into something far stranger and far less tidy: they suppress their own scent production and acquire the colony’s chemical signature directly from the ants themselves. In effect, they become living imposters — accepted not because the ants were “meant” to host them, but because natural selection has honed the beetles’ ability to exploit a biological loophole.

Ten-thousand-year-old genomes from southern Africa change picture of human evolution – Uppsala University

The story emerging from the latest palaeogenomic research reads like a science fiction epic — only it’s real, deep, and immutably ancient. A new study published in Nature reports that prehistoric humans in southern Africa lived in virtual genetic isolation for tens of thousands of years, diverging so far from other branches of Homo sapiens that their genomes fall “outside the range of genetic variation” seen in any living people. These weren’t minor differences; the DNA of individuals who lived south of the Limpopo River for much of the last 100,000–200,000 years retains an astonishing reservoir of variation, some of which has since vanished from other populations.

This isn’t an update to a dusty side-note in human history. It’s a profound rewriting of our origin story. Instead of a simple, uniform lineage emerging neatly from a single place and time, the evidence shows a complex mosaic of populations, genomes and adaptations evolving in parallel, sometimes in long-term isolation, sometimes intermingling. What we once thought of as the “standard” range of human genetic diversity was simply a tiny slice of a much richer prehistoric past.

For those committed to a literal reading of ancient texts like the Bible, discoveries like this pose a stark challenge. The creationist narrative — anchored in a literal six-day creation a few thousand years ago, followed by the dispersion of humankind from a single family — simply cannot grapple with human populations that were genetically distinct for hundreds of millennia before any traditionally assumed timeline. And yet, even here, one predictable excuse will surface: “God planted the evidence as a test of faith.”

That response, however, collapses under the very theological claims it purports to defend. The Bible repeatedly asserts that God is truthful and incapable of deceit — that “God cannot lie” (Titus 1:2; Numbers 23:19; Hebrews 6:18). If we accept those texts at face value, it follows that the Creator would not embed misleading evidence in the earth’s deepest strata as a cosmic trap for intellect. Instead, what we see in the genetic record is precisely what natural processes — mutation, isolation, selection, drift and admixture — predict and what evolutionary theory models with remarkable fidelity.

Malevolent Design - The Malaria Parasite Is Irreducibly Complex And Has Complex Specified Genetic Information - Oops!

Malaria: Newly Identified “Crown” Stage Controls Parasite Reproduction

Researchers from the Hebrew University of Jerusalem have uncovered yet another layer of exquisite molecular sophistication in one of humanity’s most persistent and lethal parasites, Plasmodium falciparum, the chief cause of malignant malaria. Their findings, reported in a recent press release and published in the peer-reviewed Journal of Cell Biology, describe a newly identified regulatory “crown” checkpoint that controls parasite reproduction with remarkable precision.

It is difficult to imagine a discovery more awkward for Intelligent Design creationists, because Plasmodium falciparum is precisely the sort of organism that embodies everything Michael Behe and William Dembski insist cannot arise by evolution. Here is complex specified genetic information, tightly regulated developmental choreography, and interlocking biochemical machinery operating across multiple life stages — the very definition, we are told, of “irreducible complexity”.

Unfortunately for the Discovery Institute, this irreducible complexity does not produce a bird’s wing, a human eye, or some uplifting example of divine craftsmanship. It produces malaria — a parasite responsible for immense suffering and hundreds of thousands of deaths every year, mostly children. If complexity is meant to be a hallmark of intelligent design, then the designer’s portfolio includes some rather grim specialities.

The problem is compounded by the fact that Michael Behe has already made malaria central to his arguments. In The Edge of Evolution, he famously pointed to the parasite’s resistance to anti-malarial drugs as an example of the supposed limits of Darwinian evolution, claiming that multiple coordinated mutations were beyond the reach of natural selection. Yet malaria has since become one of the clearest demonstrations that evolution not only occurs, but does so rapidly and repeatedly, exploiting enormous population sizes and intense selection pressures to produce exactly the adaptations Behe claimed were improbable.

As Kenneth Miller pointed out, Behe's mathematical sleight of hand was to assume resistance had to evolve as a single event in a single cell, not across a large population over time - a fallacy of which any good microbiologists should have been aware.

This newly described “crown” stage is simply the latest reminder that biological complexity is not evidence of supernatural design. Evolution predicts complexity wherever it confers survival advantage — including in parasites, pathogens, and diseases. The only real surprise is that creationists continue to present complexity as a theological virtue, when nature so often deploys it in the service of exploitation rather than benevolence.

As ever, none of this will deter creationists from repeating their familiar articles of faith. Faced with an organism whose life cycle resembles a biochemical symphony — regulated checkpoints, specialised invasion machinery, host-cell remodelling, immune evasion, and reproductive stages split between mosquito and human — they will insist that this is not evidence for evolution but evidence against it. The argument, such as it is, runs that complexity must have been present from the start, because it could not have arisen gradually.

But this is simply the old “irreducible complexity” claim in a new disguise: the assertion that because creationists personally cannot imagine intermediate stages, no such stages could have existed. Science, of course, is not obliged to conform to the limits of anyone’s imagination. Evolution does not require that complex systems appear in a single leap. It proceeds by modification of what already exists — co-option, duplication, repurposing, and incremental refinement over deep time — producing the layered complexity we observe today.

Another common retreat is the insistence that this is merely “microevolution”, the trivial shuffling of genes within some mythical created “kind”. Yet Plasmodium falciparum is not merely adjusting the colour of its spots. It is evolving novel biochemical strategies, repeatedly acquiring drug resistance, fine-tuning developmental regulation, and exploiting host environments with extraordinary efficiency. If this is “only microevolution”, then the term has been drained of all meaning.

Refuting Creationism - A Gap-Filling Miniature Dinosaur from 120 Million Years Before 'Creation Week'

Tiny new dinosaur Foskeia pelendonum reshapes the dinosaur f | Vrije Universiteit Brussel

Researchers from the Vrije Universiteit Brussel (VUB), working with colleagues in Spain and elsewhere in Europe, have just described a remarkable new species of dinosaur from the Early Cretaceous of northern Spain. Their findings are the subject of a read-only paper in Papers in Palaeontology.

The tiny herbivore, named Foskeia pelendonum, lived around 125 million years ago, yet it is already forcing palaeontologists to rethink part of the ornithopod family tree. The discovery provides another striking example of how the fossil record continues to grow in detail, resolution, and explanatory power.

This will come as an unwelcome development for creationists, who still cling to the claim that evolution is “just speculation” and that the fossil record contains no meaningful evidence of transitional relationships or evolutionary diversification. On the contrary, finds like Foskeia show exactly what evolutionary science predicts: new lineages appearing in the right strata, in the right environments, with a mixture of ancestral and derived traits that help clarify how later forms evolved.

Creationists will, of course, respond in the usual way. Some will insist that this dinosaur is “just another dinosaur”, as though classification and evolutionary relationships are irrelevant. Others will retreat to the vacuous assertion that it represents merely “variation within a kind”, without ever defining what a “kind” is or explaining why such variation produces a nested hierarchy that maps so precisely onto geological time. And as always, the more committed will simply dismiss the evidence altogether, because no amount of fossil discovery can compete with a belief system that must remain true regardless of what the rocks contain.

Yet the significance of Foskeia pelendonum lies precisely in the details. This was not simply a juvenile form of a larger dinosaur, but a genuinely small-bodied species, confirmed by bone histology to have reached adulthood. Even more intriguingly, it possessed unexpectedly specialised skull and dental features, showing that evolutionary change does not always follow the simplistic “bigger and more advanced” caricature imagined by creationists, but often proceeds through ecological experimentation, miniaturisation, and adaptation to local conditions.

Far from undermining evolutionary theory, discoveries like this strengthen it. They refine the dinosaur family tree, help fill long-recognised gaps in the ornithopod record, and demonstrate once again that the history of life is written not in Bronze Age mythology but in the sedimentary archive of deep time — an archive that continues to contradict creationism with every new fossil unearthed.

Refuting Creationism - How A Chance Mutation Allowed The Evolutionary Transition From Invertebrates To Vertebrates

New discovery sheds light on evolutionary crossroads of vertebrates | University of St Andrews news

Researchers from the University of St Andrews, working with colleagues from the University of Aberdeen and the University of Oxford, have identified a pattern of gene evolution that appears to have been crucial to the origin and subsequent diversification of vertebrates from their common ancestry with invertebrates. They have just published their findings in BMC Biology.

This discovery will be a major disappointment for creationists who cling to the notion that there is no evidence for what they call “macroevolution” — a term so ill-defined that it can be stretched to mean whatever a creationist happens to need at the time. Sometimes it is invoked to mean the origin of a new species, at other times a new genus, an entire new order, or even the biologically absurd idea of one species giving birth to an individual belonging to a completely different order. More often, though, “macroevolution” is said to mean the origin of entirely new anatomical structures.

Even that definition collapses immediately under scrutiny. Asked what novel structure humans possess that chimpanzees lack, “macroevolution” abruptly becomes the evolution of anything creationists choose to label a “kind” — another conveniently nebulous term, defined precisely nowhere and flexibly everywhere.

Yet if the origin and diversification of vertebrates does not qualify as “macroevolution”, it is difficult to imagine what possibly could. The St Andrews–led team has shown that this transition was enabled by gene evolution — that is, mutation acted upon by natural selection — affecting the genetic control of cell signalling during embryonic development. These changes influence when and where new cell types arise as a developing embryo progresses from a single-celled zygote to a complex multicellular organism, complete with differentiated tissues and specialised organs.

As this gene regulatory system evolved, it allowed the vertebrate phylum to diversify into the many classes and orders that now dominate marine and terrestrial ecosystems. No doubt this will require yet another round of misrepresentation by creationists, along with further blurring of the already elastic definitions of “macroevolution” and “kinds”.

The climate in Catalonia was much rainier 10 million years ago - Universitat Autònoma de Barcelona - UAB Barcelona

A paper published a few days ago in the Journal of Mammalian Evolution describes how the climate in Catalonia was much wetter 10 million years ago than it is today, with rainfall roughly twice the present rate, and how this was reflected in the evolution of mammals in the region. The study was conducted by palaeontologists at the Institut Català de Paleontologia Miquel Crusafont (ICP-CERCA), in association with colleagues from the Universitat Autònoma de Barcelona (UAB).

This must be deeply frustrating for creationists because, no matter how much they ignore the evidence, misrepresent it, or shout abuse at scientists, the evidence stubbornly refuses to support creationism and invariably supports evolution over deep time on an ancient Earth. The findings presented in this paper are, of course, no exception.

Scientists have previously established a close link between rainfall and the composition of mammalian communities, with wetter conditions favouring insectivores. Increased rainfall promotes the development of forests, which in turn provide abundant niches for insects and other invertebrates—the primary food source of insectivorous mammals. This relationship between small mammals and climate was first studied in detail by Jan van Dam, an associate researcher at the ICP. Van Dam developed equations that allow both average annual rainfall and its seasonal distribution to be estimated from fossil assemblages of small mammals.

Building on that earlier work, the present study analyses the abundant fossil record of small mammals to reconstruct populations that changed dynamically through time in response to shifting climatic conditions—exactly as predicted by the Theory of Evolution. There is, unsurprisingly, no evidence of spontaneous creation of species, nor of a global biological reset caused by a genocidal flood a few thousand years ago.

One of Earth’s most abundant organisms is surprisingly fragile

Microbiologists at the University of Southern California (USC) have discovered that one of Earth’s most abundant species, the SAR11 bacterium, has a fundamental — and potentially fatal — ‘design’ flaw. They have just published their findings in Nature Microbiology, and it should make grim reading for any creationists with sufficient courage to read it.

When you have trillions of copies, what does it matter to ‘selfish’ genes if a few billion go wrong and end up destroying the organisms they travel through time in? For an evolved organism, it matters not one tittle or jot to its genes, because they can always produce more copies. So long as there is a sufficiently large population to keep replicating, they will continue to exist and reproduce — and they have no other ultimate function. This is all they evolved to do.

But could we say the same for an organism designed by an omniscient, intelligent designer? What would be intelligent about creating an organism that, under particular but entirely predictable conditions, attempts to reproduce but succeeds only in making repeated copies of its DNA, fails to divide, and enters a runaway cycle of replication until it becomes so disorganised that it can no longer survive and effectively self-destructs?

SAR11 dominates the surface waters of the world’s oceans and accounts for around 40% of marine bacterial cells. As such, it is a vital component at the base of the marine food chain, and is so successful partly because of a process known as genetic streamlining — the evolutionary loss of genes to reduce energy demands in nutrient-poor environments. This alone is not the main problem for creationists to explain, although it does raise the obvious question of why a designer would burden an organism with a genetic load it does not need in the first place.

The real problem is that this streamlining, as an evolved process, comes at a cost. In shedding a load of mostly surplus genes, some essential ones are lost too — including genes that regulate the cell cycle. The result is a failure to divide after genome replication, with the cell instead entering an uncontrolled loop of DNA replication without division.

How on Earth can that be regarded as intelligent design? The organism does exactly what it is ‘designed’ to do under conditions of low nutrient stress, but in doing so falls into an inescapable trap. The consequence is that populations continue to decline even when nutrients later become available again — with potentially serious knock-on effects for other species higher up the food chain.

Malevoent Design - Has Creationism's Divine Malevolence Been Up To Its Old Tricks? - Another Bat Virus Modified To Infect Humans.

Bats Identified as Origin of Unexplained Acute Respiratory Illness and Encephalitis in Bangladesh | Columbia University Mailman School of Public Health

paper just published in Emerging Infectious Diseases by a team led by Nischay Mishra, of the Columbia University Mailman School of Public Health, shows that Pteropine orthoreovirus (PRV) — a bat-borne orthoreovirus — has crossed the species barrier into humans in Bangladesh, causing a Nipah-like illness that is difficult to distinguish clinically from Nipah virus infection. The disease presents primarily as an acute respiratory infection, sometimes accompanied by encephalitis.

It has long been known that bats possess a markedly more effective antiviral immune system than humans. This fact alone presents a problem for creationists who insist that humans — and, conveniently, themselves — are the special creation of an omnibenevolent deity. There is no coherent reason why such a deity would equip bats with a superior immune system while leaving humans comparatively vulnerable, unless the intention were for humans to suffer more infectious disease than is strictly necessary.

However, the bat immune system appears to have a significant evolutionary trade-off. Rather than eliminating viruses entirely, it often suppresses their pathological effects while allowing persistent infection. As a result, bats function as biological incubators in which viruses can circulate, diversify, and evolve. Inevitably, some of these variants acquire the ability to cross species barriers and infect humans. This remains the most parsimonious explanation for the emergence of SARS-CoV-2, the virus responsible for COVID-19 — the pandemic of 2020–2022 that killed tens of millions of people and inflicted severe damage on the global economy.

Creationists argue that complex, specified genetic information must be supplied by their putative intelligent designer and then, by a glaring act of circular reasoning, claim that the mere existence of such information constitutes evidence for that designer. This line of argument has no more merit than insisting that tins of baked beans can only be made by magic pixies, and therefore that the existence of tins of baked beans proves the existence of magic pixies. It is a form of reasoning that functions only for those who lack even a basic grasp of logic.

An additional difficulty for creationists is that PRV could only become infectious to humans if it possessed the precise genetic features required for that capability. Within the internal logic of intelligent design apologetics, the zoonotic PRV must therefore count as the product of deliberate design — and hence as evidence for a malevolent intelligent designer. The usual response is to abandon any pretence that intelligent design is science rather than religion in disguise, and to retreat into Christian fundamentalism, invoking “the Fall” and claiming that some other supernatural entity was empowered to interfere with creation and design its own suite of pathogens and parasites. This claim borders on blasphemy even within Christian theology, which traditionally reserves the creation of living things exclusively to their deity.

The prolific-waste reproductive strategy of Late Jurassic dinosaurs has been highlighted in a paper published in a New Mexico Museum of Natural History and Science Bulletin by a team of palaeontologists led by Dr Cassius Morrison of University College London’s Department of Earth Sciences.

The team constructed a detailed food web using fossil data laid down around 150 million years ago in the Morrison Formation of the United States. The Morrison Formation is a prominent sequence of Upper Jurassic sedimentary rocks (approximately 156–147 million years old) spanning around 1.5 million square kilometres across the western United States. It is North America’s most prolific source of dinosaur fossils, preserving vast deposits of mudstone, sandstone, and limestone formed in ancient river systems and floodplains.

Their analysis revealed that a major food source for carnivorous dinosaurs consisted of the young of the largest herbivores. These animals followed a reproductive strategy in which large numbers of offspring were produced and then effectively abandoned after hatching. Such juveniles would have been abundant, vulnerable, and easy prey for predators. This strategy is a familiar one in biology and only makes sense as the outcome of evolutionary processes. As an intelligently designed reproductive strategy, however, it is difficult to make sense of at all.

This is yet another example of the prolific waste that characterises living systems and betrays the absence of intelligent foresight in their design. Prolific waste and unnecessary complexity are hallmarks of evolution, whereas minimal waste and minimal complexity are the defining features of genuinely intelligent design — a distinction I explore in detail in my book The Unintelligent Designer: Refuting the Intelligent Design Hoax.

Malevolent Design - How Complex Specified Genetic Information and Irreducible Complexity Cause Pancreatic Cancer

Study reveals protein linked to spread of pancreatic cancer through nerves

A paper just published in Molecular and Cellular Endocrinology shows how precisely the sort of complex specified information and irreducible complexity that Discovery Institute fellows William A. Dembski and Michael J. Behe proclaim as evidence of intelligent design can instead combine to ensure that pancreatic cancer survives, metastasises, and ultimately kills its victims.

This, of course, is true of many diseases, which simply would not exist unless the right combination of genetic information were present and functioning correctly for the disease itself. Yet creationists routinely compartmentalise their beliefs so that harmful “designs” are excluded and blamed on something else, while only those features that appear to benefit humans are credited to a designer.

In the case of parasites, what is harmful to humans is often beneficial to the parasite, but once again the presence of harm causes the logic of creationist arguments to shift. No longer is this evidence of intelligent design, but of something called “sin”, which appears to operate as an autonomous entity capable not only of corrupting creation but of designing living organisms and manipulating their genomes. The formerly omnipotent, omnibenevolent and omniscient designer god now seems strangely impotent, indolent, or indifferent in the face of this alternative “designer”.

This theology also sits uncomfortably alongside another core fundamentalist belief: that God has a plan for everyone, and that everything that happens in a person’s life occurs as part of this divine plan. Presumably, then, that plan must include any diseases they suffer from, including cancer.

It is therefore difficult to see how creationists can escape the conclusion that their god designs and causes cancer as part of this plan, while continuing to cling to the claim that intelligent design is inherently benevolent.

Refuting Creationism - Stone Tool Sophistication and Multiple Hominin Species in East Asia - 150,000 Years Before 'Creation Week'

Stone tool manufacture in China

Discovery challenges long-held beliefs on early human technology in East Asia - Griffith News

Researchers from the Chinese Academy of Sciences, in collaboration with palaeoanthropologist Michael Petraglia of Griffith University, have just published an open-access paper in Nature Communications presenting evidence of advanced stone-tool technology dating to between 160,000 and 72,000 years ago in China.

This represents a significant shift in our understanding of the development and diversity of stone-tool technologies in East Asia. For many years it was assumed that stone technology in China lacked complexity and sophistication because bamboo provided a more versatile alternative — the so-called “Bamboo Hypothesis”. Archaeologists now have compelling reasons to revise that view.

If there is one thing calculated to excite creationists, it is the fact that scientists frequently change their minds when the evidence changes — an essential feature of the scientific method. In the simplistic binary worldview common to creationism, however, science is either right or wrong. Any revision of conclusions is therefore taken as proof that science is “wrong”, and that creationism wins by default, without needing to provide any supporting evidence of its own.

From this it follows, in the creationist imagination, that if scientists were wrong about stone-tool technology in China, they must also be wrong about human evolution and the age of the Earth. Consequently, the very evidence that caused scientists to revise their views — sophisticated tools securely dated to 160,000–72,000 years ago — must itself also be wrong. Few creationists seem to notice the paradox of arguing that science must be wrong because evidence corrected it, while simultaneously insisting that the correcting evidence is also wrong. Within the confines of the creationist rabbit hole, believing six impossible things before breakfast merely requires practice.

Nevertheless, the evidence from Xigou, in the Danjiangkou Reservoir region of central China, shows that stone-tool manufacture was not only an advanced skill but may also have been practised by more than one species of hominin. By this time, humans had already diversified into several relatively large-brained species, well before modern Homo sapiens had migrated into Eurasia in significant numbers.

The tools themselves show clear evidence of hafting — the fitting of handles to stone implements — representing the earliest known composite tools in East Asia. This implies an ability to plan ahead and to understand how tool performance could be enhanced, combined with a high level of technical skill and craftsmanship.

Scientists solve the mystery of why termite kings and queens are monogamous - The University of Sydney

Researchers from the University of Sydney have just published a paper on termite evolution in Science which will make depressing reading for any creationists brave enough to attempt it. The study comprehensively refutes several articles of creationist faith.

A common creationist assertion is that loss of genetic information is invariably fatal, so mutations cannot be selected for during evolution. They also insist that evolution, as defined by science, is necessarily a process of increasing complexity, which they then claim would violate the laws of thermodynamics by reducing entropy.

The absurdity of this counter-factual claim is easy to see. Variation between individuals is due to genetic differences, and that variation is only possible if mutations generate novelty. Creationists also conveniently ignore the fact that entropy can decrease locally in open systems. Earth is very much an open system, with a continuous influx of energy from the Sun, so nothing in thermodynamics precludes local increases in order or complexity.

Moreover, the claim is demonstrably false. Many endoparasites, such as parasitic worms, have lost substantial amounts of genetic information as they evolved to rely on their hosts for key functions. Several intestinal worms, for example, have no digestive tract at all, because they absorb nutrients directly from their host’s gut. Evolution does not require an increase or a decrease in complexity as such; it requires only a change in the frequency of alleles in a population over time.

The University of Sydney researchers have now identified another striking example of evolution by gene loss — this time in termites. Their results show a massive loss of genes as termites evolved extreme monogamy and sociality. Paradoxically, a reduction in genetic complexity at the individual level was accompanied by an increase in social complexity at the colony level.

Some of the lost genes are those responsible for producing sperm tails, meaning that termite sperm can no longer swim. This is likely a consequence of strict monogamy within the colony, which removes sperm competition altogether. In species where females mate with multiple males, there is strong selection pressure for highly motile sperm, because the fastest are more likely to fertilise the eggs. In termites, that pressure simply does not exist.

To reach these conclusions, the team — led by Professor Nathan Lo — compared the genomes of ‘domestic’ cockroaches (which share a common ancestor with termites), closely related wood roaches that live in small family groups, and multiple termite species exhibiting different levels of social complexity.

Refuting Creationism - Blood Tests On Ancient Fossils - And What They Can Tell Us

Life in fossil bones: what we can learn from tiny traces of ancient blood chemicals

A paper recently published in Nature details the application of a new field known as palaeometabolomics to reconstruct ancient African environments and track how they changed over time.

Modern medicine can learn a great deal about our health and lifestyle from a blood test, because blood contains traces of metabolites derived from the food we eat, as well as indicators of liver and kidney function and how effectively metabolic waste is disposed of.

But what if we could perform blood tests on archaic animals and human ancestors? Over time, this could tell us not only what they ate, but how their diets changed, which in turn reveals changes in rainfall, temperature, vegetation cover — forest versus savannah — and the species that were hunted and consumed.

Unintelligent Design - One Design Blunder Led To Another And Ended Up Causing Cancer - Or Was It Deliberate?

A broken DNA repair tool accelerates aging | News from Goethe University Frankfurt

Researchers from Goethe University, Frankfurt am Main, Germany, have shown how a faulty DNA repair mechanism triggers inflammation and leads to accelerated ageing, developmental abnormalities, and cancer.

Their findings are published in Science.

As I explained in my book, The Unintelligent Designer: Exposing the Intelligent Design Hoax, one of the hallmarks of an evolved system — and one which creationists have been conditioned to mistake for evidence of intelligent design — is complexity. In reality, the opposite is true: intelligently designed objects and processes are typically *minimally

complex, doing exactly what is required and no more.

One reason complexity arises in evolved systems is the need for additional layers of processes to compensate for the suboptimal designs that evolution inevitably produces. An intelligently designed process — especially one devised by a designer endowed with foresight — would require no such compensatory mechanisms. It would function reliably every time and be robust enough to withstand environmental stressors and other causes of malfunction. Nor would a perfectly designed copying process be prone to copying errors.

What we observe in reality, however, is an excessively complex system that still malfunctions — and when it does, it can do so unpredictably and catastrophically, leading to increased suffering and even death. The equivalent, in engineering terms, would be an aircraft manufacturer producing planes that were mostly safe most of the time, yet costly to build because they relied on intricate back-up systems to compensate for other components prone to failure — and which nevertheless suffered unpredictable mid-flight failures when those back-ups failed, causing aircraft to fall from the sky. Such an incompetent aircraft manufacturer would not remain in business for long.

In contrast to evolved systems which are overly complex and still prone to errors, an intelligently designed organism would be minimally complex, maximally efficient, robust enough to withstand environmental stressors and work perfectly every time. As so often, what ID predicts is not what we actually observe. In normal science, the falsification of a hypothesis is regarded as confirmation that the hypothesis was wrong, but in creationism the reverse holds; if the facts fail to confirm the hypothesis the facts must be wrong. The hypothesis must be clung to with grim determination, come what may.

Refuting Crationism - How Climate Change Shaped the Evolution of Kangaroos And Wallabies

QUT - Study maps climate-related evolution of modern kangaroos and wallabies

In a clear example of how evolution is driven by environmental change, a study by scientists at Queensland University of Technology (QUT), led by Professor Matthew J. Phillips, has shown how closely the evolution of Australia’s kangaroos and wallabies maps onto the continent’s long-term climate history. Their findings are published in Molecular Phylogenetics and Evolution.

By tracing the climate record over the last 18 million years and comparing it with the fossil record, the team showed that increasing aridity and habitat variability around 7–9 million years ago coincided with the emergence of the macropodines — the group to which most modern kangaroos and wallabies belong. This was followed by the appearance of incipient grasslands around 5–4.5 million years ago, a period that saw a major diversification of kangaroo and wallaby species.

As expected, there is no evidence of sudden creation without ancestors 6,000–10,000 years ago, nor of a wholesale biological reset following a global flood a few thousand years ago. Instead, the record is one of gradual evolution over deep time, driven by environmental change. The long-predicted failure of the Theory of Evolution to explain and make sense of the evidence once again failed to materialise, as it has every time creationists have claimed it was imminent over the past half-century.

Rather than contradicting evolutionary theory, the evidence fits it like a hand in a glove, adding yet another piece to the growing mountain of supporting data. Once again, the underpinning theory of modern biology is shown to be supported by independent lines of evidence from geology, climatology, and palaeontology, all converging on the same conclusion: life has evolved on an ancient planet responding continuously to changing environments.
