Rare fossil at Montana State’s Museum of the Rockies records Tyrannosaurus attack

A paper published on 17 February 2026 in PeerJ by Taia C.A. Wyenberg-Henzler of la of Montana State University, USA, reports on a remarkable fossil from the Hell Creek Formation of eastern Montana: a nearly complete, articulated skull of an adult Edmontosaurus annectens with the broken tip of a tyrannosaur tooth still embedded in its left nasal bone.

The fossil dates from the closing stages of the Late Cretaceous, roughly 66 million years ago, shortly before Edmontosaurus, Tyrannosaurus and all other non-avian dinosaurs disappeared during the Cretaceous–Palaeogene mass extinction. The bone surrounding the embedded tooth shows no evidence of healing or remodelling, indicating that the bite occurred at, very near or shortly after the death of the Edmontosaurus.

In other words, this is physical evidence of a violent interaction between predator and prey tens of millions of years before humans existed—precisely the sort of evidence that creationists are conditioned to reject because it cannot be accommodated within their mythology. According to young-Earth creationism, there was supposedly no death, predation or suffering before human ‘sin’ allowed evil to enter the world and ruin their omnipotent creator’s previously perfect creation—apparently without that omnipotent creator either foreseeing or preventing it. And all this supposedly happened only 6,000–10,000 years ago, shortly after ‘Creation Week’.

The doctrine that no animal died before ‘the Fall’ is not stated explicitly anywhere in the Bible. It is a theological inference imposed upon the text because young-Earth creationism requires it. It belongs to the category of reasoning that says: ‘This must be true for the rest of my beliefs to be true; my beliefs cannot be wrong; therefore, this must also be true.’

Having granted themselves this assumption of infallibility, creationists must then protect it from every fact that contradicts it. The belief cannot be mistaken, so the evidence must somehow be misunderstood, fraudulent, planted by Satan, created with the appearance of age or otherwise unworthy of consideration. Anything, in fact, is preferable to the intellectually honest admission that the belief itself has been falsified.

In almost every other field of human endeavour, such a supremely arrogant claim to personal infallibility would be laughed at and its proponent told to grow up. Yet, when packaged as religious faith, it is not merely tolerated but frequently treated with respect. Its advocates demand—and often receive—special privileges and social status: ‘You must listen to me, allow me to make laws governing your life and let me shape society according to my beliefs because I have an invisible friend and wear special robes.’

And so creationism staggers on, obliged to deny a veritable deluge of scientific evidence rather than concede that its mythology bears no resemblance to the history of life on Earth.

Refuting Creationism - How Physics Constrained The Evolution Of Flight in Flies

Carlos Faulquier

As a child growing up in the relative silence of a North Oxfordshire hamlet, I could sometimes hear bats overhead. On a still summer night, lying in the quiet of my bedroom, I could also make out the distinctive, high-pitched whine of a mosquito as it approached an exposed arm, guided at close range by body heat as well as by carbon dioxide and human odours. Both sounds now lie beyond what my ageing ears can detect. The relevance of that mosquito’s whine will become apparent shortly.

A paper published on 9 July 2026 in PLOS Biology by scientists from Wageningen University in the Netherlands and Aix-Marseille Université in France explains how aerodynamic constraints have channelled the evolution of flight across the Diptera — the order of insects that includes houseflies, fruit flies, mosquitoes, midges and crane flies.

The researchers examined the body and wing morphology of 133 species and recorded the hovering flight of 46 of them using high-speed stereoscopic cameras. They then used computational fluid dynamics to reconstruct the aerodynamic forces and energy costs associated with their wing movements.

They found that wing shape varied considerably and was strongly influenced by evolutionary ancestry, but that wingbeat movements were broadly conserved across most of the order. Despite the enormous diversity of dipterans in size, appearance, habitat and ecology, most have evolved strikingly similar flight mechanics because the physical requirements of remaining airborne restrict the range of workable solutions.

Evolution, of course, depends upon heritable variation, but not every imaginable variation is viable or advantageous. A change that demands more energy without providing some compensating benefit is unlikely to spread through a population. Natural selection therefore tends to channel evolution towards a comparatively narrow range of effective solutions. In this case, the need to generate sufficient lift while limiting aerodynamic power consumption has produced a broadly shared flight pattern across most dipterans.

It must be galling for those few creationists who can read and understand scientific papers, yet are still eagerly awaiting the long-promised day when biologists abandon “Darwinism” and embrace creationism, to encounter paper after paper such as this one. Once again, evolutionary theory provides the accepted framework within which the observations make sense, without so much as a hint that the researchers are preparing to replace it with supernatural magic.

An enterprising creationist might nevertheless seize upon the apparent exceptions. Mosquitoes and their close relatives, the midges, do not follow the usual energy-saving pattern. Mosquitoes can beat their wings as many as 1,000 times each second, using almost three times as much aerodynamic power as similarly sized fruit flies. Crane flies also depart from the general pattern, although in the opposite direction, having evolved unusually economical flight.

Surely, the creationist might argue, if aerodynamic constraints channelled the evolution of the other flies, mosquitoes should have been constrained in precisely the same way. If an exception exists, perhaps there is something wrong with the theory.

But this objection rests on the mistaken assumption that natural selection must optimise every characteristic for a single purpose. Evolution does not produce organisms in which each structure is independently perfected. It produces compromises between competing demands, with reproductive success ultimately determining which combination of costs and benefits persists.

The researchers found that mosquitoes and midges produce disproportionately powerful sounds for insects of their size. Their rapid, low-amplitude wingbeats generate increased aerodynamic drag and require enlarged flight muscles, making flight more energetically expensive. That apparent inefficiency, however, may provide a substantial reproductive advantage because acoustic communication plays an important part in their courtship.

Creationism Refuted - Earth Is 'Fine-Tuned' For Disasters And Mass Extinctions

Researchers confirm cause of Earth’s biggest mass extinction | Stanford Doerr School of Sustainability

Studying the metabolism of living brachiopods like these collected from San Juan Island, Washington, allowed Stanford researchers to understand how the physiology of the modern fauna and Paleozoic fauna may have differed and how these groups would have been differentially impacted by oxygen and temperature changes during the Permian–Triassic mass extinction.

Many of Earth's climatic, geological and biological processes behave as complex, nonlinear systems, resembling systems in chaos. In this context, “chaotic” does not mean random. It means that small differences in starting conditions can sometimes be amplified until they produce very different outcomes — the phenomenon popularly known as the “butterfly effect”. The butterfly is not literally responsible for a distant storm; it merely illustrates how a tiny disturbance can cascade through a sufficiently complex system.

This is not the picture of a planet engineered to remain permanently benign or perfectly “fine-tuned” for life — still less for human life in the United States. Earth is habitable, but its habitability is contingent and sometimes precarious. The same interacting atmospheric, oceanic, geological and biological processes that sustain life can, when pushed beyond critical thresholds, drive abrupt environmental change, ecological collapse and mass extinction.

At several points in Earth's history, reinforcing feedbacks have transformed relatively small initial disturbances into rapid and profound environmental changes. Organisms adapted to the previous conditions were then confronted with combinations of heat, cold, acidification, oxygen loss or other stresses occurring too quickly for most populations to adapt. The result was widespread extinction.

What has been less well understood is why some groups were devastated while others living in the same changing environment survived. This is an important question for us because every organism alive today is descended from lineages that somehow survived every previous mass extinction.

Research by a Stanford University-led team, recently published in the Proceedings of the National Academy of Sciences of the United States of America (PNAS), now offers an experimentally supported explanation for one of the most striking patterns associated with the end-Permian mass extinction — the “Great Dying” of about 252 million years ago.

Creationism Refuted - Why The Human Body Refutes Intelligent Design And Supports Mindless Evolution.

The human body isn’t a masterpiece of design – it’s a patchwork of evolutionary compromise

Back in December 2024, I published The Body of Evidence: How the Human Body Refutes Intelligent Design as part of my Unintelligent Design series. In it, I argued that:

Looked at objectively, beneath the superficial appearance of design, the human body, with its inefficiencies, vulnerabilities and vestigial features, is best explained through the lens of evolution.

Far from reflecting intelligent design, our anatomy and physiology reveal a history of incremental changes shaped by natural selection and constrained by pre-existing structures. These imperfections underscore the reality of evolution as a tinkering process, producing functional but far-from-perfect outcomes.

In this light, the human body stands as a powerful testament to our evolutionary heritage and tells a story far more impressive than the childish notion of it all being made by magic by a super-intelligent yet invisible and undetectable designer.

It is therefore gratifying to see those conclusions independently reinforced by Lucy E. Hyde, a Lecturer in Anatomy at the University of Bristol. In a recent article in The Conversation, she makes essentially the same case, drawing upon many of the same examples that I used.

This is not because anatomists and evolutionary biologists have agreed upon a preferred story and then set out to make the evidence fit it. It is because people who understand evolution and possess more than a superficial knowledge of human anatomy and physiology can examine the same evidence and independently reach the same broad conclusion: the human body is not the product of foresightful engineering but a historical patchwork of inherited structures, evolutionary compromises and modifications to what already existed.

Evolution explains not only why the human body works as well as it does, but also why it so often fails, why some of its structures follow absurdly circuitous routes, why others are poorly suited to their present functions and why still others persist despite having little or no remaining usefulness. “Intelligent design”, by contrast, explains none of this without retreating into the scientifically worthless claim that an unknowable designer must have wanted things that way.

Creationism Refuted - Giant Kangaroos In New Guinea - 1,500 Years Before 'Creation Week'

Impression of Protemnodon tumbuna

Giant kangaroos survived until 6,500 years ago on the New Guinea coast.

It is probably fair to say that no branch of science is a friend of creationism. That is presumably why creationists devote so much time and effort to trying to discredit science—often without the slightest appreciation of the irony of using computers and the Internet, both products of science and engineering, to tell the world that science does not work. Yet their attitude towards science is not merely hostile but opportunistic: whenever they encounter a scientific finding that they think can be misrepresented as supporting creationism, they suddenly become jubilant champions of ‘the evidence’.

Archaeology is one of the most persistent threats to literalist creationism. Far from confirming the biblical narrative, it repeatedly uncovers evidence of human cultures, environmental changes and extinct animals extending far beyond the few thousand years permitted by Young Earth Creationism. Nor does archaeology stand alone. Its findings repeatedly converge with those of genetics, palaeontology, geology and climatology to produce the same coherent history—a history in which neither a recent magical creation nor a global genocidal flood leaves the slightest trace.

True to form, a recently published paper in the journal npj Biodiversity, by an Australian-based team of archaeologists and palaeontologists, presents evidence from New Guinea that simply could not exist if the biblical narratives of a magical creation a few thousand years ago, followed by a global flood about 4,300 years ago, bore any resemblance to reality. The evidence indicates that a large extinct kangaroo relative—probably Protemnodon tumbuna—survived on the northern coast of New Guinea until the Middle Holocene, perhaps as recently as about 6,500 years ago.

This was tens of thousands of years after every known species of Protemnodon had disappeared from Australia, where the genus is thought to have become extinct by about 41,000 years ago, along with most of the continent’s other megafauna.

Protemnodon tumbuna was a stocky, muscular forest-dwelling kangaroo weighing an estimated 50–90 kilograms—roughly comparable in size to a modern red kangaroo. Unlike modern large kangaroos, however, it was probably predominantly quadrupedal, using its powerful forelimbs to move through dense forest and hopping only inefficiently and for short distances, if at all. It was one of seven currently recognised species of Protemnodon known collectively from Australia and New Guinea.

Creationism Refuted - How Humans Acquired Their Pathogens From Their Animals - No Magic 'Sin' Involved

AI-generated image (ChatGPT 5.5 Thinking)

We’ve long suspected that the transition to farming and animal husbandry opened the door to a new era of disease – now DNA shows us that it happened at least 6,500 years ago,” says Professor Eske Willerslev, author of the new study.

Illustration: William Brøns Petersen

Young Earth creationist mythology has it that sin, shortly after the magical creation of two adult humans, caused death and disease to enter the world. Until then, so we are expected to believe, there had been no disease and nothing ever died — not even, apparently, the plants Adam, Eve and the other animals ate.

Reality, of course, is materially different from the mythology produced by scientifically ignorant ancient pastoralists and later scribes who knew nothing of bacteria, viruses, parasites, epidemiology or evolution, and who interpreted misfortune in magical terms. Disease was not a supernatural punishment introduced at a single moment by a talking snake, a disobedient couple and an irritable god. It was, and remains, a biological process involving organisms evolving, spreading, adapting and, sometimes, crossing from one host species into another.

And the evidence now shows that at least 6,500 years ago, diseases were passing from animals into the humans who lived alongside them. The domestication of animals, the growth of settled farming communities and the rise of pastoralism brought humans, livestock, waste, parasites and pathogens into much closer proximity than before. This has long been thought to explain why humans suffer from so many infectious diseases. It is also a point Jared Diamond made in Guns, Germs and Steel: The Fate of Human Societies, where he argued that Eurasia’s abundance of domesticable animals, and Europeans’ long exposure to the diseases associated with them, helped Europeans to dominate other populations, often with their pathogens acting as an advance guard against peoples with no previous exposure or immunity.

That view of the zoonotic origin of many human diseases has now been strongly supported by the work of researchers led by Professor Eske Willerslev, of the University of Copenhagen and the University of Cambridge, in a study published open access in Nature in July 2025. The team analysed DNA from more than 1,300 prehistoric individuals, some up to 37,000 years old. Their bones and teeth provided an extraordinary archive of ancient microbial DNA, revealing traces of bacteria, viruses and parasites that infected humans across deep Eurasian history.

The results suggest that close cohabitation with domesticated animals, together with large-scale migrations of pastoralists from the Pontic Steppe, played a major role in the spread of zoonotic diseases. The researchers found that identifiable zoonotic pathogens first appear in their data from around 6,500 years ago, became more widespread after about 6,000 years ago, and peaked roughly 5,000 years ago — precisely the sort of pattern expected if lifestyle, animal husbandry, mobility and population contact were driving disease transmission.

This is especially awkward for creationists because the evidence does not point to a sudden, supernatural transformation of the world’s biology. It does not show disease appearing overnight as the result of a mythical “Fall”. Instead, it shows a long, historical and evolutionary process, unfolding through early Eurasian human history as changing human behaviour created new ecological opportunities for pathogens.

Malevolent Design - The Complex Mechanism That Helps Bacteria Make Us Sick

Creationists have a problem of their own making. The same evolutionary processes they try to rebrand as evidence for a creator god are also the processes that produce parasites, pathogens and the molecular machinery by which they exploit their hosts. If Michael J. Behe wants to claim “irreducible complexity” as evidence of design, and William A. Dembski wants to claim “complex specified information” as the signature of an intelligent designer, then they cannot confine those arguments to the parts of biology they find theologically convenient. The same kinds of complexity and genetic information are also found in organisms that make us sick and increase the suffering in the world.

Although professional creationists, including fellows of the Discovery Institute such as Behe and Dembski, are careful to avoid naming their putative designer, their audience invariably identifies it with the supposedly omnibenevolent god of the Bible, Torah and Qur’an. But that creates an obvious problem: using their own criteria, this creator god must be credited not only with designing humans and other animals, but also with designing the bacteria, viruses, parasites and molecular mechanisms that infect, disable and kill them.

The significance of this is often lost on creationists because it requires a basic understanding of biology and a willingness to follow an argument to its logical conclusion. When they cite Behe’s favourite examples, such as the E. coli flagellum or anti-malarial drug resistance in Plasmodium falciparum, as evidence for their god, they are in effect crediting that god with designing mechanisms that help microbes move, invade, survive and evade our attempts to stop them. Point this out, however, and the same evidence that was allegedly scientific evidence for intelligent design is suddenly reinterpreted as evidence for “The Fall” and “Original Sin”. The pretence that creationism is science is abandoned in a hasty retreat into fundamentalist theology, where the same facts are repurposed to reach a more comfortable conclusion.

In addition to the two examples I recently discussed here and here, another example has now been reported — and this one involves a powerful molecular motor that should, by creationist standards, look very much like the sort of thing they would normally call “designed”. It is the type IV pilus retraction system, recently reported in Proceedings of the National Academy of Sciences of the USA (PNAS), which many bacteria use to retract tiny hair-like surface structures called pili. These pili act like microscopic grappling hooks, helping bacteria attach to surfaces and tissues, form antibiotic-resistant biofilms, and pull in fragments of DNA from their surroundings, including genes for drug resistance acquired from other bacteria.

Refuting Creationism - Humans Were Living In A West African Rain Forest 140,000 Years Before 'Creation Week'

According to the findings of an international team led by the Max Planck Institute of Geoanthropology, with contributions from the University of Sheffield, published in February 2025 in Nature, humans were living in the wet tropical forests of what is now Côte d’Ivoire about 150,000 years ago — more than 140,000 years before creationists imagine their mythical “Creation Week”, when they believe the single ancestral couple of all modern humans was created by magic somewhere in the Middle East.

The date itself is no surprise to anyone who understands the real evolutionary history of our species. Anatomically modern Homo sapiens had emerged in Africa by about 300,000 years ago, and the evidence increasingly points not to a single cradle, but to a pan-African process involving populations adapted to different regions and environments. What is striking about this discovery is not that humans were present in Africa 150,000 years ago, but that they were living in a tropical rainforest — an environment long assumed to have played only a minor, late role in human evolution.

That older assumption fitted neatly with the simplified “savannah hypothesis”, in which the ancestors of humans were thought to have diverged from the lineage leading to chimpanzees and bonobos as climatic change fragmented African forests and created more open grassland and woodland habitats. In that view, rainforest was more of a barrier than a formative environment. But the emerging picture is far more interesting: early H. sapiens were not simply creatures of open savannahs, coasts or grasslands, but members of a flexible, adaptable species able to exploit a wide range of African habitats long before the later dispersals into Eurasia.

Part of the reason rainforest environments have been under-represented in accounts of human evolution is that they are poor places for preserving bones, artefacts and organic remains. Acidic soils, heavy rainfall, dense vegetation and rapid biological decay all work against the survival of the archaeological record. That makes the Bété I site in southern Côte d’Ivoire especially important. Using optically stimulated luminescence and electron spin resonance dating methods, the researchers constrained the onset of human occupation there to around 150 ka. Plant-wax biomarkers, stable isotope data, phytoliths and pollen from the associated sediments then showed that the environment at the time was wet tropical forest.

This pushes the earliest known secure evidence of human occupation of a rainforest environment back by about 80,000 years. It also suggests that tropical forests were not late, marginal or forbidding habitats into which modern humans only ventured after acquiring some special new cultural trick, but part of the ecological range within which H. sapiens was already living during the Middle Pleistocene.

The finding was made possible because modern dating and environmental reconstruction techniques could be applied to sediments associated with stone tools first found at the site in the 1980s. In other words, once again, patient science has extracted a coherent, evidence-based history from the ground — a history that would not exist at all if there had been a recent global genocidal flood churning the world’s sediments into the chaotic mess required by creationist mythology.

Refuting Creationism - How Consciousness Emerges From An Unconscious Brain - No Magic Required

AI-generated image (ChatGPT 5.5 Thinking)

Researchers discover advanced language processing in the unconscious human brain | BCM

One of the more persistent claims made by creationists, especially those who have learned that “irreducible complexity” and “no transitional fossils” are not arguments so much as slogans, is that science can never explain consciousness. Consciousness, we are assured, is something special, something non-material, something breathed into us by a creator god; the magical ingredient that separates humans from the rest of the animal kingdom and places us conveniently at the centre of creation.

It is, of course, another argument from ignorance: science has not yet explained every detail of consciousness, therefore God. The same argument was once used for lightning, disease, embryology, instinct, inheritance, morality and the origin of species. In each case, the alleged supernatural mystery retreated as evidence accumulated and natural mechanisms were discovered. Consciousness is now going the same way — not because science has solved every philosophical puzzle about subjective experience, but because neuroscience is steadily showing that the mental processes creationists like to wrap in mystery are ordinary biological processes carried out by ordinary neural tissue.

A striking example of that comes from a paper published in Nature by researchers at Baylor College of Medicine and collaborating institutions. The researchers recorded activity from neurons in the human hippocampus while patients were under general anaesthesia during surgery for drug-resistant epilepsy. This gave them a rare opportunity to observe what the brain was doing when the patients were, in the ordinary sense, unconscious.

What they found is deeply inconvenient for anyone who wants consciousness to remain a supernatural mystery. Even under anaesthesia, hippocampal neurons responded to unexpected sounds, showed evidence of short-term plasticity, and, most remarkably, processed spoken language. When patients were played short stories, neural activity in the hippocampus carried information about word frequency, semantic category and grammatical class, and even contained signals predictive of upcoming words.

In other words, processes we might once have assumed belonged to conscious awareness — distinguishing parts of speech, extracting meaning and anticipating what comes next in a sentence — were taking place without the patient being aware of them. The brain was not merely ticking over like an idling machine; it was analysing, categorising and predicting. Consciousness, then, is not where all the clever work is done. Much of the clever work appears to be done before consciousness ever gets involved.

That does not mean this paper has “solved” consciousness, nor do the authors claim that it has. What it does show is that the boundary between conscious and unconscious processing is not where many people intuitively imagine it to be. Consciousness is looking less like a magic light switched on by a soul, and more like a higher-level state arising from coordinated activity across brain systems — a state in which some of the brain’s processing becomes integrated, reportable and available to the organism as experience.

For creationists, that is the problem. Their argument depends on consciousness remaining mysterious enough to hide a god in it. But neuroscience keeps doing what science always does: replacing mystery with mechanism, awe with understanding, and supernatural assertion with testable evidence. Once again, the choice is not between “science knows everything” and “therefore God”; it is between a research programme that discovers how things work and a religious apologetic that depends on hoping we never find out.

Malevolent Design - A Brilliantly 'Designed' Process For Spreading Influenza - Malevolence or Evolution?

Dead cells after the self-destruction and fragmentation process. The large green areas are the “eat me” signals which alert immune cells to kick-start clean-up and recycling process, while the small green circles are the “Footprint of Death” F-ApoEVs left behind by the dying cell.

’Footprint of Death’ gives new clues to cell life, News, La Trobe University

My previous post was about the discovery, reported in Cell Host & Microbe in May 2026, that a single amino-acid change in a coronavirus protein can alter how a bat-related coronavirus interacts with the immune systems of bats and humans. In the case of SARS-CoV-2, the virus that causes COVID-19, such changes help to explain how a virus that may be relatively benign in its natural host can become a serious pathogen when it crosses the species barrier into humans. By creationists' own criteria, this should qualify as intelligent design.

This post concerns another example which, if creationists applied their criteria for intelligent design consistently, would be further evidence of malevolent design. It is the finding, reported in Nature Communications, that influenza A virus can exploit part of the normal process of programmed cell death to help infect neighbouring cells.

Applied consistently, these discoveries would portray creationists' putative designer god as a malevolent entity that designs ways to increase suffering. But, since creationists need to portray this alleged designer as the omnibenevolent god of the Bible, this supposed 'evidence of intelligent design' somehow ceases to be evidence of design at all and becomes evidence of 'Sin' and 'The Fall', as creationists abandon any pretence of science and retreat into Biblical mythology to explain away inconvenient facts.

The discovery, by a team led by PhD candidate Stephanie Rutter in Professor Ivan Poon’s lab at the La Trobe Institute for Molecular Science (LIMS), shows how each step in the process of cell death and renewal is important in helping a dying cell break down and be cleared away by the body’s immune system. The team found that, as cells self-destruct, they change shape, lift away from their surroundings, and leave behind a residue which the researchers dubbed the 'footprint of death'. This contains a previously undescribed type of extracellular vesicle (EV). EVs are small packages used by cells to transport proteins, lipids, DNA and RNA to other cells, acting as an important means of communication between cells.

These new vesicles, known as FOOD-derived apoptotic extracellular vesicles, or F-ApoEVs, normally mark the site of a dead cell and help the immune system identify and clear away the remaining fragments, preventing inflammation and other harmful consequences. But this useful clean-up process can also be turned into a weakness. The researchers found that, when dying cells are infected with influenza A virus, viral proteins and even virus particles can be carried in these F-ApoEVs, providing another route by which infection can spread to neighbouring cells.

Had this process been beneficial to humans, rather than to influenza viruses, creationists would doubtless hail it as a marvel of intelligent design by their god. Yet, because the benefit is to a virus and the result can be disease, suffering and death, the same kind of complexity somehow ceases to count as evidence of design and is quietly reclassified as a mysterious consequence of 'The Fall'.

Creationists get into this bind because they are trying to force the evidence into their preferred mythology. Science has no such problem. The immune system, cell-death pathways and the pathogens that exploit them are all products of evolutionary history, not foresight. They are parts of a continuing arms race in which every useful biological process presents opportunities for parasites, viruses and other pathogens to exploit. An influenza virus that stumbles upon a weakness in a host system does not need to understand it, plan it, or design it; it merely needs to leave more copies of itself than viruses that did not.

Malevolent Design - How SARS-CoV-2 Was Cleverly Designed to Jump From Bats To Humans - Evolution Or Malevolence

A Single Molecular Change May Help Viruses Jump from Bat to Human | UC San Francisco

Two recent papers should delight admirers of creationism's putative intelligent designer, because both show the sort of biochemical ingenuity they normally rush to claim as evidence of design. One, published in Cell Host & Microbe in May 2026 and reported by UCSF in June, shows how a single molecular change can alter the way a coronavirus interacts with bat and human immune systems, helping to explain how viruses related to SARS-CoV-2, the virus that caused the COVID-19 pandemic, can cross the species barrier. The other, published in October 2025 in Nature Communications, which will be the subject of my next blog post, shows how influenza A virus can exploit the remnants of dying cells to help spread infection to neighbouring healthy cells.

However, that excitement is likely to be tempered somewhat when it dawns on them that, if these systems are the products of intelligent design, their designer can only be regarded as malevolent, since the result is an increase in the sum total of suffering in the world. But this does not seem to trouble ID proponents who cite Michael J. Behe's favourite examples — the Escherichia coli flagellum and anti-malarial drug resistance in Plasmodium falciparum — as evidence of irreducible complexity and hence of intelligent design, while ignoring the awkward fact that these supposed examples of design help microorganisms survive, move, infect, or evade human attempts to control them.

This puts creationists in a familiar bind. On the one hand, they like to claim any useful biological complexity as evidence of their Biblical god. On the other, when the same logic points to a designer of pathogens, parasites, immune evasion, drug resistance and viral spread, they retreat into vague claims about 'Sin', 'The Fall', or some mysterious corruption of nature, thereby absolving their god of responsibility for the very mechanisms they were praising as designed only moments earlier.

The first paper, in Cell Host & Microbe, was by a large team of researchers from the University of California San Francisco (UCSF) Quantitative Biosciences Institute, the Icahn School of Medicine at Mount Sinai, the Institut Pasteur and the Fred Hutchinson Cancer Center. It showed that a single amino-acid change in a viral protein can alter how coronaviruses interact with bat and human immune systems, changing the host's response to infection.

Bats are important viral reservoirs because their immune systems and physiology can allow them to tolerate viruses that might cause serious disease in other mammals. They can therefore harbour viruses for long periods, providing opportunities for viral lineages to persist, diversify and acquire mutations that may matter greatly when those viruses encounter a new host species. The UCSF-led study helps to explain how relatively small genetic differences can make the difference between a virus that remains associated with a bat reservoir and one that is better able to evade human immune defences.

This is precisely the sort of thing creationists should, by their own logic, have to call 'complex specified information'. The change is functional; it affects a specific biological outcome; and it is beneficial from the point of view of the viral lineage. The problem, of course, is that creationists usually smuggle in the assumption that 'beneficial' must mean beneficial to humans. If it benefits a virus, a bacterium, a parasite or a cancer cell, they suddenly decide it does not count.

Comparing SARS-CoV-2 with a related bat coronavirus, RaTG13, the researchers found that a viral protein called ORF9b was a key factor. The SARS-CoV-2 and RaTG13 versions of ORF9b are very similar, but behave very differently. In human cells, the SARS-CoV-2 version helped disable an innate immune alarm system, allowing the virus to multiply more effectively. In bat cells, the RaTG13 version interacted with a restriction factor that helped suppress infection.

The team found that changing just one of ORF9b's roughly 100 amino acids reversed its ability to evade the immune response. In creationist thinking, if the phrase is to mean anything at all, this would be new functional genetic information. Yet the actual explanation requires no magic, no designer and no supernatural intervention: a mutation changed an amino acid; that change altered protein interactions; and the result affected viral fitness in different host-cell environments. In other words, ordinary chemistry and physics, operating through mutation, selection and host-virus interaction, produced exactly the kind of functional change creationists insist cannot happen naturally.

The paper in Cell Host & Microbe was accompanied by a news item from UCSF by Levi Gadye:

Refuting Creationism - Observed Evolution In A South African Leopard Population

The elusive Cape leopard.

Jana Ohrner/iNaturalist, CC BY-NC

Leopards adapted to South Africa’s Cape so successfully that they’re genetically unique – study

This paper will have creationists hurriedly trying to redefine evolution so that it no longer means what biologists mean by it — change in allele frequencies in a population over time — but instead becomes some childish parody of the idea, carefully constructed to exclude the scientific definition and so safely miss the point. The paper, published last January (2026) in Heredity, shows that a small, isolated population of leopards (Panthera pardus) in South Africa’s Cape Floristic Region is a striking example of incipient allopatric divergence, and possibly early speciation, in progress. The population, estimated at fewer than 1,000 individuals, has developed a distinctive genome and includes small leopards, some with only about half the body mass of leopards elsewhere in Africa.

In what will also disappoint those creationists who are still eagerly awaiting the abandonment of “Darwinism” by mainstream biologists and its replacement by magic-based creationism, the authors — an international group of leopard conservationists and evolutionary biologists — interpret their findings wholly within the framework of evolutionary theory. By comparing whole-genome data from 43 leopards, including 10 from the Western Cape province (WCP), the team found that the WCP leopards diverged from those of northern South Africa about 20,000–24,000 years ago — in other words, many thousands of years before creationists’ mythical “Creation Week”. They found no obvious evidence that genetic drift alone was responsible for this divergence, and concluded instead that it is more likely to reflect the population’s demographic history, long-term isolation and adaptation to the Cape’s distinctive environmental conditions, including low prey availability.

Their conclusion is that the leopards of the Western Cape can be regarded as an evolutionarily significant unit (ESU): a genetically distinctive population representing a unique component of the species’ evolutionary history and therefore one that should be managed and conserved as such.

Ancient Fire Record Rewritten: Researchers Push Earliest Evidence of Human Fire Use Back to over a Million Years | EUROPEAN FRIENDS OF THE HEBREW UNIVERSITY

A recent paper in PLOS ONE, by an international team including Dr Liora Kolska Horwitz of the Hebrew University of Jerusalem, reminded me of a quote by Francis Collins, former director of the Human Genome Project and founder and president of The BioLogos Foundation, which aims to reconcile Christian theology with science. It also reminded me how Young Earth Creationists traditionally cope with information that refutes their beliefs. The paper reports evidence for the use of fire in a South African cave by early hominins between 1.07 million and 1.79 million years ago — a fact entirely inconsistent with Young Earth Creationism (YEC).

This image of God as a cosmic trickster seems to be the ultimate admission of defeat for the Creationist perspective. Would God as the great deceiver be an entity one would want to worship? Is this consistent with everything else we know about God from the Bible, from the Moral Law, and from every other source—namely, that He is loving, logical, and consistent?

Thus, by any reasonable standard, Young Earth Creationism has reached a point of intellectual bankruptcy, both in its science and in its theology. Its persistence is thus one of the great puzzles and great tragedies of our time.

Francis Collins - The Language of God

In this quote from The Language of God, Francis Collins is referring to those Young Earth Creationists who dismiss the palaeontological, archaeological and cosmological evidence for life evolving on an old Earth in an even older Universe, as evidence deliberately created by God to test the faith of believers. Creationists also routinely dismiss this sort of evidence either by accusing scientists of faking it, or by attributing it to the work of Satan.

All of these are, of course, variations on conspiracy thinking — more understandable in a teleologically thinking toddler than in an adult. When it persists into adulthood, it is consistent with the findings of a psychology research paper which found that creationism and conspiracism share a common teleological bias: the tendency to explain events and natural phenomena as though they exist for a purpose, or are directed towards some hidden end. It is therefore no surprise that creationism so often depends on conspiracism. The surprise is that there are still so many people, especially in parts of the USA, who try to understand the world around them using a cognitive habit most children eventually learn to leave behind.

Creationism Refuted - Our Ancestors Lived In North America - 56 Million Years Ago

Life reconstruction of Teilhardina

Our primate ancestors evolved in the cold – not the tropics

At times, it seems almost cruel to keep reminding creationists that another day, another week and another month have passed, and still there is no hint that biomedical scientists are about to abandon evidence-based evolutionary biology and adopt magic-based creationism as a better explanation of the facts. And yet here we are again: another paper, another article, and another example of evolution providing the rational framework for interpreting the evidence.

And, to rub salt into creationist wounds, the evidence deals with events around 56 million years before creationists’ mythical “Creation Week”. As though to refute yet another creationist myth — that scientists are only allowed to publish papers that confirm mainstream scientific orthodoxy — the findings, published by Jorge Avaria-Llautureo of the University of Reading and colleagues in the mainstream journal Proceedings of the National Academy of Sciences of the USA (PNAS), challenge the long-standing assumption that the primate lineage originated in warm tropical forests.

The study maps the likely geographic origins of our primate ancestors and reconstructs the historical climate at those locations. Its conclusion is surprising: early primates appear to have lived, dispersed and diversified through cold, arid and temperate regions, not primarily in the tropics. Their later colonisation of tropical regions took several million years and seems to have been driven more by local changes between dry and wet climates than by global warming itself.

One useful example is the tiny early primate Teilhardina, a small, tree-dwelling mammal known from fossils around 56 million years old — roughly 10 million years after the extinction of the non-avian dinosaurs. Fossil evidence suggests that Teilhardina had nails rather than claws, helping it grasp branches and handle food, a characteristic associated with primates. Species of this early primate group appear in the fossil record of North America and then dispersed rapidly across what are now Europe and China.

An article explaining the finding and its significance for understanding our evolutionary origins was published in The Conversation by Jason Gilchrist, a lecturer in the School of Applied Sciences at Edinburgh Napier University.

Unintelligent Design - The DNA In A Developing Brain Gets Broken And Has To Be Repaired - Incompetent Design Or Evolution?

Neurons migrating through dense tissue in the developing brain (green) frequently undergo DNA damage (magenta).

DNA in neurons is damaged and repaired during brain cortex formation | News | Kyoto University iCeMS

Like my last post, this post illustrates how the human body, far from being the perfect design of the omnipotent, omniscient designer creationists would have us believe in, is the result of a utilitarian evolutionary process. Layers of complexity arise, not from divine brilliance, but from evolved solutions to problems created by suboptimal earlier solutions to other problems — which were themselves the result of imperfect evolution.

In the previous post we saw how DNA replication is sufficiently imperfect that it requires mechanisms to repair the resulting DNA damage. However, these repair processes are themselves potentially dangerous and need control systems to maintain a careful balance between too little and too much repair. When this control process fails, it can lead to cancers that mimic those caused by the BRCA1 and BRCA2 genes, which are associated with increased risk of breast and ovarian cancer.

In this post we see how newborn neurons in the developing brain need to squeeze through tight spaces in dense tissue, past other cells and between fibres, in order to reach their final positions and form neural circuits in the cerebral and cerebellar cortices. This process is such a physical struggle that the DNA in these neurons can suffer double-strand breaks and must be repaired quickly to ensure normal brain development. This is the finding of a research team from Kyoto University, the University of Tokyo, Osaka University, the National University of Singapore and the Tokyo Metropolitan Institute of Medical Science, led by Professor Mineko Kengaku who have just published their findings in Nature.

Mostly, this repair is quick and successful. However, the research team also found striking similarities between the development of mice in which the repair process failed and human genome-instability syndromes that affect the cerebellum.

Another important point is that this repair process appears to be much more successful in damaged neuronal DNA than in similar damage that can occur when some cancer cells migrate through narrow channels. The difference seems to lie in where the DNA breaks occur. In neurons, they tend to occur in regions of the genome that are not actively being transcribed, whereas in cancer cells the damage can involve essential genes. That suggests there is some biological bias in where these breaks occur in neurons, rather than the process being simply random mechanical shattering.

This raises the obvious question for creationists: why create a process that breaks DNA in developing brain cells, only to require another process to repair it, with the inherent risk that the repair process might be incomplete or imperfect? It also raises the possibility that the resulting small differences in the genomes of individual neurons could contribute to neuronal individuality and perhaps to some neurodevelopmental or neurodegenerative diseases.

The emerging picture, from this and from the rogue repair-control process that can mimic cancers caused by the BRCA genes, is not of a human body designed by an omniscient engineer. It is more like a William Heath Robinson contraption: improvised, overcomplicated, dependent on compensatory mechanisms, and always vulnerable to the failure of the very systems needed to keep it working.

DNA repair protein gene gone rogue may unlock new cancer treatments | Penn State University

A characteristic of evolved biological systems, and one that distinguishes them from systems designed from first principles, is that they are often unnecessarily complex, vulnerable to failure and dependent on layers of patchwork compensation. This is what we should expect from systems produced by utilitarian, suboptimal compromises built from whatever was available at the time.

With no plan, no foresight and no predetermined objective, natural selection can only favour whatever leaves more descendants in a particular environment. The result is not an ideal solution, but merely a workable one — one that is better than what preceded it, even if it remains a very long way from perfection. An intelligent designer, such as the one proposed by advocates of intelligent design, would be under no such historical constraints and could, in principle, rebuild a system from scratch to arrive at the optimal solution.

To illustrate this, this post and the next will look at two recent papers that incidentally demonstrate how many human health problems arise from these over-complex, error-prone systems — systems that would not exist if the human body were the pinnacle of created perfection that creationists imagine it to be. Unless, of course, the designer intended us to suffer when its systems failed.

The first concerns a paper published in February 2026 in Nature Communications by researchers at Penn State College of Medicine. It shows how one component of the DNA repair machinery — a system needed because DNA replication and maintenance are themselves vulnerable to error and damage — can itself go wrong and produce a pattern of genomic instability resembling that seen when the BRCA1 and BRCA2 tumour-suppressor pathway is defective.

The culprit is EXO1, a gene that encodes an exonuclease involved in DNA processing and repair. In normal cells, EXO1 helps trim and process damaged or mismatched DNA so that repair can proceed. But when EXO1 is overexpressed, as the researchers found in a significant proportion of several cancers, including about 20–30% of breast and ovarian cancers as well as melanoma, testicular, cervical and hepatobiliary cancers, too much of this normally useful protein becomes destructive. Instead of helping to preserve genome integrity, excessive EXO1 activity can degrade newly synthesised DNA during replication stress, expanding single-stranded DNA gaps and degrading reversed replication forks.

The result is a BRCA-like pattern of genomic instability even in cells whose BRCA pathway is still functional. In other words, the cell behaves in some important respects like a BRCA-mutant tumour cell, not because BRCA1 or BRCA2 is mutated, but because too much EXO1 has overwhelmed the normal protective system. This matters clinically because such tumours may respond to some of the same treatments used against BRCA-mutant cancers, including drugs that target DNA repair vulnerabilities.

So, we have a DNA replication and maintenance system that needs elaborate repair machinery because the genome is constantly vulnerable to damage; then we have the catastrophic consequences when that repair machinery itself goes rogue. Compare that with the simpler, more robust system we might expect from an intelligent designer endowed with foresight and unconstrained by evolutionary history. Complexity is not the hallmark of intelligent design that creationists claim it to be. In biology, it is very often the accumulated consequence of failure-prone, suboptimal compromises produced by evolutionary tinkering without a predetermined objective.

Refuting Creationism - Evolution of Cultivated Cotton - No Magic Required

Cotton’s roots trace to Yucatan Peninsula, where wild gene pool runs deepest - News Service

My last blog post looked at the evolution of the strawberry and how the evidence of multiple whole-genome duplications and speciation by hybridisation refutes several basic creationist, counter-evidential myths and articles of faith.

This post deals with the evolution and cultivation of the cotton plant, which again refutes the childish notion of divine creation, perfectly suited for use by the creator god's favourite creation, humankind, as well as the creationist article of faith that no new genetic information can arise without the direct intervention of a designer god, because this would supposedly violate the laws of thermodynamics.

As a recent paper in Proceedings of the National Academy of Sciences of the USA (PNAS), by a team of researchers including Professor Jonathan Wendel of Iowa State University, has shown, modern upland cotton, Gossypium hirsutum, is the result of thousands of years of human selection acting on naturally occurring genetic variation. The team traced its domestication to the Yucatán Peninsula in Mexico, probably to the north-western Yucatán, where wild populations still retain the deepest gene pool. Cotton was first domesticated there about 5,000 years ago, which, if creationist chronology were taken seriously, places it before the supposed genocidal global flood, which it appears to have survived along with the people who cultivated it.

The researchers found that domestication transformed a wild, perennial shrub with small bolls and short, coarse, brown fibres into the modern crop with abundant, long, fine, white fibres. This was not the result of a single act of magical design, nor of a sudden, miraculous improvement, but of long-term selection acting on many mutations of relatively small effect, accumulated and filtered over many generations.

The team also showed that, while human selection produced fibres more useful to people, it did so at a cost. Useful traits present in wild populations, such as disease resistance and salt tolerance, were left behind as farmers selected repeatedly from a restricted subset of the original wild gene pool. Each generation of selection narrowed the genetic base still further, pushing cultivated cotton through a genetic bottleneck.

The researchers reached these conclusions by comparing the genomes of cultivated cotton with those of specimens collected from wild populations across the plant's native range. Their analyses showed that domesticated cotton is most closely related to wild cotton from north-western Yucatán, where two random wild plants still show, on average, about twice as much genetic difference as two random modern cultivars.

After cultivated upland cotton spread out of the Yucatán, it eventually became the dominant cotton crop worldwide, displacing or overshadowing other cotton species that had been independently domesticated in South America, Africa and India. Today, Gossypium hirsutum, or upland cotton, accounts for about 90% of the world's cotton crop.

Refuting Creationism - How The Strawberry Evolved - No Magic Needed

Doubtless God could have made a better berry, but doubtless God never did

Dr. William Butler, Physician - (1535–29 January 1618)
Talking of the strawberry.

This and my next blog post deal with essentially the same refutations of creationist mythology and pseudo-science. The mythology is the Bible’s unambiguous claim that a creator god made everything for its favourite creation, humankind; the pseudo-science is the creationist claim that no new genetic information can arise without the direct intervention of that creator god, because, so they tell us, new genetic information can only be produced by magic, otherwise it would violate the laws of thermodynamics [sic]. Both claims are demonstrable nonsense, of course.

The first example concerns a fruit now ripening in UK gardens and fields — the strawberry. If strawberries had been specially created for humans, we might expect them to have arrived fully formed, already perfect for our tastes and purposes. Instead, like other cultivated crops, they bear the marks of a long evolutionary history followed by recent human selection, breeding and improvement.

A May 2025 paper published in the journal Horticulture Research by researchers from the U.S. Department of Agriculture and collaborating institutions, describes a new way to reconstruct the deep evolutionary history of the cultivated strawberry, Fragaria × ananassa. Their work helps explain how the modern strawberry acquired its complex octoploid genome — not by magic, but by ordinary, natural processes of genome duplication, hybridisation and subsequent evolutionary divergence.

Cultivated strawberries, like many crop plants, are polyploids. Humans are normally diploid, with two sets of chromosomes; cultivated strawberries are octoploid, with eight sets. In the notation used by geneticists, humans are 2n, while the cultivated strawberry is 2n = 8x = 56. This genomic complexity is the outcome of a series of ancient whole-genome duplication and hybridisation events in which entire chromosome sets from different ancestral lineages were brought together in one organism.

Whole-genome duplication does not require supernatural intervention. It is a well-known natural process, especially common in plant evolution. Initially, it duplicates existing genetic material, but those extra gene copies then provide raw material for mutation, altered regulation, divergence, subfunctionalisation and neofunctionalisation. In other words, duplicated genes can be retained, modified, silenced, repurposed or combined in new ways. Hybridisation adds another layer of novelty by bringing together different genomes, producing new combinations of genes and regulatory networks in a single evolutionary lineage.

The research team disentangled the strawberry’s complex polyploid genome by exploiting the evolutionary signatures left by long terminal repeat retrotransposons, or LTR-RTs. These mobile genetic elements accumulate in genomes over time and can act rather like molecular time stamps. By comparing patterns of similarity between these elements across chromosomes, the researchers were able to reconstruct the strawberry’s subgenome architecture and infer the timing of major genome-merging events.

Using this serial similarity matrix method, the researchers found evidence for three successive allopolyploidisation events in the evolutionary history of the cultivated strawberry genome: first between about 3.1 and 4.2 million years ago, then between about 1.9 and 3.1 million years ago, and finally between about 0.8 and 1.9 million years ago. The result is a genome composed of multiple subgenomes with different ancestry, interacting and evolving together over time.

What is perfectly clear from this research is that new genetic variation and genomic complexity can arise through entirely natural mechanisms. Polyploidy, hybridisation, mutation, transposable elements and selection are not gaps in biology into which a magic creator needs to be inserted; they are part of the normal machinery of evolution. The cultivated strawberry is not evidence of special creation, but of a long, traceable evolutionary history later shaped by human cultivation.

Creationism Refuted - Why Science Works While Religions Ignore Failures

Dark diversity helped solve Darwin’s 160-year-old puzzle | University of Tartu

A paper recently published in Proceedings of the National Academy of Sciences of the USA (PNAS) by an international team that included researchers from the University of Tartu, Estonia, offers a solution to a conundrum in evolutionary ecology first identified by Charles Darwin more than 160 years ago: Darwin’s naturalisation conundrum.

The problem concerns why some introduced species successfully establish themselves in a new environment while others fail. Darwin recognised two apparently contradictory possibilities, both of which make sense in evolutionary terms. On the one hand, a newcomer closely related to local species might succeed because its relatives show that the environment is suitable for that general way of life. In other words, similarity to the local community could be a sign of pre-adaptation. On the other hand, a newcomer might be more successful if it is unlike the resident species, because it avoids direct competition and exploits resources the local community is not already using.

So which is it? Should a successful immigrant species resemble the local species, or should it be different from them? That is Darwin’s naturalisation conundrum.

These are the sorts of paradoxes science thrives on because they expose a gap in understanding and invite investigation. They are not waved aside as mysteries, nor protected from scrutiny by declaring them ineffable. They are problems to be solved by evidence.

That is in stark contrast to religion, where glaring contradictions are often preserved rather than resolved. Christianity, for example, asks its followers to believe simultaneously in an omniscient god and in human free will. Yet the contradiction can be exposed with a simple question: if God has always known that you will eat fish for dinner tomorrow, can you choose steak instead? If yes, then God did not know after all; if no, then you were never free to choose. Either answer undermines a central plank of Christian theology, because without free will there can be no meaningful original sin, no need for salvation, and no coherent reason for the Jesus story.

Another awkward question is why an omniscient god supposedly waited until about 2,000 years ago to arrange the sacrifice of Jesus as the mechanism for saving humanity. If this god had always known that a blood sacrifice would be needed, why wait through countless generations of human suffering before arranging it? Why not solve the alleged problem at the beginning? Did God simply stand by while millions died without that supposed salvation, or did it merely take until the first or second century CE for priests to invent a theological explanation for the Jesus story?

And so the list goes on. Can an omnipotent god create an object too heavy for it to lift? Can God lie? If God claims to be omniscient, how can it know that there is nothing it does not know? And if it is aware of not knowing something, then it is not omniscient. Such questions are usually met not with answers but with evasion, because religions have no neutral referee. They have only opinion, assertion and authority.

Science is different because evidence can arbitrate between competing explanations. This is why science tends to converge on a single answer while religions fragment into sects, denominations and, sometimes, mutually hostile factions.

In the case of Darwin’s naturalisation conundrum, the team, including Wen-gang Zhang and Professor of Botany Meelis Pärtel of the University of Tartu, examined the evidence in the form of a remarkable 340-year dataset from Swedish lakes, recording both successful and unsuccessful fish introductions. This allowed the researchers to test, with unusual precision, what determines whether an introduced species establishes itself.

What if humans could regrow tissue? Texas A&M study moves science closer – Texas A&M Stories.

Although the Discovery Institute and its Fellows who advocate for Intelligent Design are usually careful not to identify their putative “intelligent designer” explicitly with the God of the Christian Bible, the dog-whistle signals they use leave their target audience in little doubt. The designer is understood to be the Christian god, merely relabelled for legal and tactical convenience. That being so, and if that god were actively interfering in the design and evolution of living systems — with humans as the supposed pinnacle of creation and occupying a special place in it — we might reasonably expect humans to have been given the best design available.

Instead, nature looks exactly as an unplanned evolutionary process would lead us to expect: a patchwork of compromises, contingencies and inherited limitations. As I describe in my book, The Malevolent Designer: Why Nature's God is not Good, humans are remarkable in some respects, particularly in our relatively large brains and consequent cognitive abilities, but in most other respects we are not especially impressive. We are not the strongest animals, nor the fastest. Birds of prey have far better eyesight; barn owls and dogs have far better hearing in relevant ranges; dogs have a vastly superior sense of smell; elephants and some other long-lived animals have evolved impressive cancer-resistance mechanisms; and the immune systems of many bats are tuned in ways that make our own look distinctly ordinary.

But perhaps the most striking contrast is in the ability of some animals to regenerate lost or damaged body parts. Several species can regenerate structures that humans simply cannot replace. Salamanders can regrow limbs; fish can replace fins and repair tissues that would leave mammals permanently damaged; and some invertebrates can regenerate astonishing portions of the body. Yet, noticeably, all the prayers, incantations and appeals to divine mercy have never once been shown to regrow an amputated human limb, replace a lost eye, repair a severed spinal cord, or restore dead heart muscle after an infarction. Nor do we see cancerous sections of colon removed by surgery obligingly regrowing as healthy tissue in answer to prayer. These are not impossible biological feats in principle; they are just things our lineage cannot normally do.

Now researchers from Texas A&M College of Veterinary Medicine and Biomedical Sciences (VMBS) have found something that should be even more disturbing for Intelligent Design creationists. In a paper recently published in Nature Communications, they report that non-regenerating mouse digit wounds can be induced to move part-way towards regeneration. In other words, the relevant mammalian cells may not be entirely incapable of regeneration; their capacity appears to be suppressed or obscured by the normal wound-healing response. Creationists who reject the evolutionary explanation now need to explain why an intelligent, omnibenevolent designer would leave mammals, including humans, with a latent capacity for regeneration, while allowing that capacity to be overridden by scarring.

The researchers’ explanation makes perfect sense as the outcome of a utilitarian, unplanned evolutionary process. In mammals, rapid wound closure by scar-forming fibroblasts can be life-saving. A quick patch reduces blood loss, closes a route for infection and gives the injured animal a better chance of surviving long enough to reproduce. Regeneration, by contrast, is slower and more complex. Evolution has no foresight and no obligation to produce perfection; it merely preserves what works well enough under the circumstances. The injury is patched up with a near-enough-is-good-enough solution, and the animal lives to pass on its genes.

That, of course, should not have been beyond the wit of an intelligent designer to improve upon. A competent designer could have given us both abilities: rapid wound closure to prevent fatal bleeding and infection, followed by orderly regeneration of the missing structures. Instead, we have the familiar evolutionary compromise: survival first, elegance later — and often not at all.

The problem centres on fibroblast cells, which can follow different developmental routes. In ordinary mammalian wound-healing, they rapidly close the wound and form scar tissue. In strongly regenerative animals, similar cells can organise into a blastema — a temporary structure that seals the wound while also providing the cellular basis for rebuilding missing tissues. The Texas A&M team showed that, after the wound had first closed, applying fibroblast growth factor 2 (FGF2), followed later by bone morphogenetic protein 2 (BMP2), could redirect the response. The result was imperfect regeneration, but it included bone, tendon, ligament and joint-like structures.

The conclusion is not that humans are about to start regrowing limbs, nor that a mouse digit is the same as a human arm or leg. It is more interesting than that. The potential for regeneration in mammals may not have vanished completely. It may still be there, hidden beneath the faster, rougher, scar-forming response that natural selection has favoured. For creationists, that raises the awkward question of why their supposed designer would equip other animals with regenerative abilities, leave traces of the same capacity in mammals, and then arrange matters so that, when humans most need it, the system normally fails.
