Wormholes may not exist – we’ve found they reveal something deeper about time and the universe

A paper published open access in January 2026 in the journal Classical and Quantum Gravity should, if creationists could understand it, shoot one of their favourite foxes: the supposed killer question, "What came before the Big Bang?"

Only a creationist could believe the absurd notion that once literally nothing existed as a state of being, and that a god — presumably also made of nothing, because there was nothing to make it from — simultaneously existed and created everything out of that nothing by casting a magic spell, spoken in a language there was no-one else to communicate with in. The first intuitive mistake in that convoluted nonsense is the assumption that the default state of existence is non-existence.

Creationists, however, hypocritically try to hold science to a much higher standard than they apply to their own nonsensical superstitions. While demanding answers to what they imagine are "Gotcha!" questions of science, they routinely dismiss any answer with a wave of the hand. One favourite "Gotcha!" is: what was there before the Big Bang? The usual response is that, in the simplest version of standard cosmology, the question may be meaningless, because time and space themselves are part of the universe being described. If time does not extend through t = 0, then there is no "before" in the ordinary sense. But to a teleologically minded creationist, the answer that there was no "before" at the Big Bang sounds like a cop-out — a way of avoiding the question.

But what if there was a "before", not in the naive sense of empty time waiting around for a universe to be inserted into it, but in the deeper sense that what we call the Big Bang may have been a transition between two time-related phases of a larger physical system?

That this is at least a theoretical possibility comes from the work of three theoretical physicists, Enrique Gaztañaga and K. Sravan Kumar of the Institute of Cosmology & Gravitation, University of Portsmouth, UK, and João Marto of the Departamento de Física, Centro de Matemática e Aplicações (CMA-UBI), Universidade da Beira Interior, Portugal. They have revisited the work of Albert Einstein and Nathan Rosen, whose 1935 paper led to the idea of Einstein–Rosen bridges. These were later popularly interpreted as "wormholes" connecting different regions of spacetime, although that was not the original purpose of the idea.

Using a quantum-field-theoretic approach, Gaztañaga, Kumar and Marto argue that Einstein–Rosen bridges may not be space-travel tunnels at all, but mathematical bridges connecting two complementary components of a quantum state — two microscopic arrows of time. In one component, time flows in the direction we experience; in the other, it is mirrored in the opposite direction. Near black holes, or in expanding and collapsing universes, both components may be needed for a complete quantum description.

This offers a possible route through the black hole information paradox: the puzzle of how information can be preserved when matter crosses an event horizon and a black hole eventually evaporates. In the authors’ interpretation, information is not destroyed; it continues to evolve through the time-reversed, mirror component of the quantum state. That would preserve the quantum requirement that information is not simply lost, without requiring science-fiction wormholes, time machines or supernatural intervention.

The idea also opens the possibility that what we call the Big Bang was not an absolute beginning, but a bounce — a quantum transition from a preceding phase of cosmic evolution. In that scenario, our universe could even be the interior of a black hole formed in an earlier, parent cosmos, where collapse on one side becomes expansion on the other. The Big Bang, in other words, would not be a magical creation event, but a natural physical gateway.

That possibility also recalls an earlier speculative but serious scientific idea proposed by Lee Smolin in 1992, known as cosmological natural selection. Smolin suggested that black holes might give rise to new universes, with the physical constants of each descendant universe varying slightly from those of its parent. Universes whose laws favour the formation of many black holes would therefore tend to leave more descendant universes, rather as organisms that leave more offspring become over-represented in a biological population.

This is not evolution by genes, of course, and it is not established fact. It is a speculative cosmological hypothesis. But it is scientific speculation of the proper kind: naturalistic, mathematically framed, open to criticism and, in principle, vulnerable to observational evidence. It stands in stark contrast to creationism, which answers the same question with nothing more substantial than magic, asserted certainty and Bronze Age mythology.

Creationism Refuted - Australian Crocodiles Are Fatal To Creationism

129,000 years of crocodiles: what we know about Australasia’s ancient apex predators

According to Bronze Age Biblical mythology, existing species should have no ancestors because they were all supposedly magicked into existence fully formed during a few days of creation, just a few thousand years ago.

That childish belief has to be clung to by creationists despite the evidence of the real world, which tells a very different story: not of sudden manufacture, but of deep evolutionary history, extinction, replacement and survival. The iconic saltwater crocodiles of northern Australia provide a good example. They are not isolated products of a one-off act of creation, but living survivors of a much richer Australasian crocodylian history stretching back tens of millions of years, during which crocodile relatives occupied a variety of ecological niches, including those of formidable predators.

Modern Australia has only two native crocodile species: the freshwater crocodile, Crocodylus johnstoni, and the Indo-Pacific or saltwater crocodile, Crocodylus porosus. But the fossil and archaeological evidence shows that these are merely the remnant survivors of a once more diverse crocodylian fauna, including the now-extinct mekosuchines, a distinctive Australasian group whose members included species very unlike the crocodiles familiar today.

Now a group of researchers from the University of Queensland and Griffith University, together with colleagues from several other institutions, has pieced together the fragmentary evidence from 26 fossil and archaeological sites across Australasia to build a clearer picture of the crocodylians that once lived in the region, and of their interactions with humans. Their review of the evidence was recently published, open access, in the Zoological Journal of the Linnean Society.

The study shows that the late Pleistocene record of Australian crocodylians is still incomplete and often difficult to date securely, but it nevertheless reveals a lost diversity. The extinct mekosuchines appear to have declined and disappeared on mainland Australia around the same broad period as other Australian megafauna, while some survived much later on south-west Pacific islands such as New Caledonia, Vanuatu and Fiji. There, their remains occur in archaeological contexts, suggesting that they persisted until after human arrival and may have been affected by human activity.

Refuting Creationism - Europe's Most Complete Stegosauria Skull - From 150 Million Years Before 'Creation Week'

Europe’s most complete stegosaurian skull unearthed in Teruel, Spain | Pensoft.blog

Another day, another dinosaur. At least, that must be how it feels to creationists trying to cling to demonstrably false beliefs by ignoring the evidence and pretending each new discovery is either a mistake, a fraud, or a sinister attempt by scientists to undermine their faith.

This time the problem comes from Teruel, Spain, where palaeontologists from the Fundación Conjunto Paleontológico de Teruel-Dinópolis have described an exceptionally well-preserved partial skull of a stegosaurian dinosaur from the Late Jurassic Villar del Arzobispo Formation, dating to about 150 million years ago. Their results, published in May 2025 in the Pensoft journal Vertebrate Zoology, identify the fossil as belonging to Dacentrurus armatus, and as the most complete stegosaurian skull yet found in Europe.

That matters because stegosaurian skulls are notoriously rare. Their bones were fragile, and the animals’ skulls were small compared with their heavily built bodies, so cranial material is much less commonly preserved than vertebrae, limb bones, plates or tail spikes. A skull as complete as this one is therefore not just another fossil for a museum drawer, but a valuable piece of anatomical evidence for understanding how these plated, quadrupedal herbivores evolved.

Using this specimen, the researchers were able to refine the known anatomy of Dacentrurus armatus and reassess the evolutionary relationships of stegosaurs more generally. Their analysis supports the division of Stegosauria into two major clades, Huayangosauridae and Stegosauridae, and they formalise a further grouping, Neostegosauria, to include later-diverging stegosaurids. In other words, one skull from Spain helps clarify not only a single European dinosaur species, but the wider evolutionary history and geographical spread of the iconic plated dinosaurs.

If nothing else, work such as this illustrates how science treats a new discovery: not as a threat to be denied, explained away or forced into conformity with dogma, but as additional evidence to be tested against existing knowledge. Where necessary, classifications are revised, hypotheses are adjusted, and understanding moves a little closer to reality.

Creationism, by contrast, starts with the conclusion and then tries to make the evidence fit. Science starts with the evidence and changes the conclusion when the evidence demands it. That is why a 150-million-year-old stegosaur skull from Spain is a contribution to human knowledge, not a theological inconvenience to be waved away.

Refuting Creationism - Collagen In a 66-Million-Year-Old Dinosaur Fossil - Time To Crank Up The Creationist Lie Machine

Discovery of collagen in fossil bone could unlock new insights into dinosaurs - News - University of Liverpool

An open-access paper published in January 2025 in the journal Analytical Chemistry will no doubt have had creationist disinformation merchants rubbing their hands with glee, because it is exactly the sort of finding they can misrepresent to their scientifically illiterate followers as 'proof' that dinosaurs lived only a few thousand years ago, provided they first wrap it in the usual recycled falsehoods about geological dating methods.

The paper, by a team led by Professor Stephen Taylor of the University of Liverpool, with colleagues from the university’s Department of Electrical Engineering and Electronics, the Materials Innovation Factory, and the Pasarow Mass Spectrometry Laboratory at the University of California, Los Angeles, reports strong evidence for preserved collagen remnants in a 66-million-year-old dinosaur fossil. The fossil in question is a 22 kg sacrum from Edmontosaurus, a duck-billed hadrosaur, excavated from Upper Cretaceous strata of the Hell Creek Formation in South Dakota.

Of course, what creationists will not be telling their followers is that this was not a case of fresh dinosaur meat, intact soft tissue, or anything remotely resembling a recently dead animal. The researchers used several independent analytical techniques. Cross-polarised light microscopy showed a pattern of birefringence consistent with collagen; tandem liquid chromatography–mass spectrometry identified and quantified hydroxyproline, an amino acid strongly associated with collagen in bone; and bottom-up proteomics detected collagen peptide sequences. In other words, the finding is evidence of degraded collagen remnants preserved within an exceptionally well-preserved fossil, not evidence that the fossil is young.

To a creationist disinformation merchant, the question will be: how can we exploit the intuitive but mistaken assumption that all proteins must decay within a few years, so that the presence of collagen remnants can be sold as 'proof' that this dinosaur died recently? To a scientist, the question is very different: since the fossil comes from rocks known from independent geological evidence to be around 66 million years old, what happened during fossilisation to allow traces of original organic molecules to persist for so long?

That contrast could hardly be clearer. Creationism begins with its conclusion and then tries to force every inconvenient fact into it. Science begins with the evidence and asks what the evidence implies. Creationists ask how the facts can be made to protect a predetermined dogma; scientists ask what has to be revised, refined, or investigated further in the light of new evidence.

The real scientific importance of this discovery is not that it challenges the age of the fossil, but that it opens up new possibilities for studying ancient life. If remnants of collagen can survive under particular fossilisation conditions, then other exceptionally preserved fossils may also retain molecular traces that can help clarify relationships between extinct animals, reveal more about dinosaur biology, and improve our understanding of how organic molecules can persist over geological time.

Creationism seeks to close down enquiry by pretending that all the answers were written down by Bronze Age storytellers. Science does the opposite: it asks better questions, develops better techniques, and adds to the sum total of human knowledge.

Refuting Creationism - Multiple Origins Of The Japanese People

DNA study challenges thinking on ancestry of people in Japan | RIKEN

In my previous post, I showed how scientists, unlike creationists, can and do change their minds when the facts change, using the example of revised dates for the repopulation of the post-glacial British Isles. In this post, I will use another example: a recent revision in our understanding of the origins of the population of the Japanese archipelago.

It had long been believed that a two-part model could largely explain modern Japanese people: indigenous Jomon hunter–gatherer–fishers and later migrants from continental East Asia, associated with rice farming and the cultural transformations that followed. However, whole-genome analysis of 3,256 people from across Japan has shown that the picture is more complex.

The new study identified three major ancestral components: Jomon, East Asian, and a north-east Asian component, most strongly represented in north-eastern Japan and possibly connected with the historical Emishi people. The study was conducted by researchers from RIKEN’s Center for Integrative Medical Sciences. RIKEN is Japan’s National Research and Development Agency and its leading national comprehensive research institute. The research was published, open access, in April 2024 in Science Advances.

The fact that the population history of the Japanese archipelago is best explained by multiple ancestral components, regional structure, migration and admixture is, of course, utterly incompatible with the childish creation and global flood genocide of Bible mythology. It is not a history of people magically created without ancestry, followed by a population reset from a single family of flood survivors. It is the history of an evolved species, carrying in its DNA the record of earlier populations, migrations, interbreeding and selection.

Nor was that the only embarrassing finding for creationists. The researchers also identified DNA inherited from archaic humans, including Neanderthals and Denisovans, in modern Japanese genomes. Some of these introgressed segments are medically relevant. For example, a Denisovan-derived region within the NKX6-1 gene is associated with type 2 diabetes and may influence sensitivity to semaglutide, a drug used to treat the condition. The researchers also identified 11 Neanderthal-derived segments associated with conditions including coronary artery disease, prostate cancer, rheumatoid arthritis and four other diseases. By way of comparison, the RIKEN article also notes earlier research showing that a Neanderthal-inherited cluster on chromosome 3, present in roughly half of all South Asians, is linked to a higher risk of respiratory failure and other severe effects of Covid-19.

In other words, the genomes of modern Japanese people, like the genomes of all modern human populations, contain the traces of real ancestry: migration, admixture, archaic introgression, natural selection and inherited vulnerabilities. This is exactly the sort of messy, contingent history that evolution predicts, and exactly the opposite of what creationists need if their mythology is to be treated as real history.

Refuting Creationism - Rapidly-Evolving Cacti

The cactus on your desk is an evolution speed machine - University of Reading

Contrary to half a century of creationist assurances that biologists are about to abandon ‘Darwinism’ and adopt creationism, two biologists from the School of Biological Sciences, University of Reading, UK, have done what scientists actually do: they used evolutionary theory to investigate why cacti have speciated so rapidly. Their conclusion was not that supernatural magic was involved, but that the tempo of evolution itself appears to be a major factor.

Taking their cue from a line of thinking that goes back to Charles Darwin’s work on orchids — including his famous prediction that a then unknown moth, with an exceptionally long proboscis would be found to pollinate a highly specialised Madagascan orchid (subsequently discovered and named Xanthopan praedicta) — botanists had reason to expect cactus diversification to follow a similar pattern. If specialised flowers drive speciation, then cactus speciation should correlate with flower length, especially where long, tubular flowers are associated with particular pollinators.

But that is not what Dr Jamie B. Thompson and Professor Chris Venditti found. They studied flower-length data for more than 750 cactus species in 107 genera, covering a 185-fold range in size, from just 2 mm to 37 cm. Despite that extraordinary variation, flower length itself was only weakly related to how fast cactus lineages split into new species. What mattered was not having a particular flower size, but how rapidly floral morphology — measured here through flower length — was evolving. In other words, faster-speciating cacti had faster-evolving flowers. Their findings have recently been published in the Royal Society’s Biology Letters.

The research was made possible by a new Open Access database called CactEcoDB, created by Jamie Thompson and ten colleagues. This database brings together cactus traits, spatial distributions, environmental variables, range estimates, speciation rates and evolutionary relationships for more than 1,000 cactus species. The result is a major new resource for studying cactus ecology, evolution, biogeography and conservation, and reflects seven years of work compiling and checking data on one of the world’s most distinctive and threatened plant families.

Refuting Creationism - Fine Tuned for Life, But Not How Creationists Imagine - No Magic Needed

How a cup of water can unlock the secrets of our Universe - Queen Mary University of London

Creationists are always on the lookout for anything in science that can be misrepresented as evidence that the Universe must have been designed, preferably by whichever locally popular god they have already decided exists. So it will not be surprising if they seize on a paper in Science Advances, as though it proves their case.

It does nothing of the sort, of course. In fact, properly understood, it does something much more interesting — and potentially much more damaging to the simplistic creationist claim that “fine-tuning” must mean “fine-tuned by an intelligent designer”.

The paper, by Professor Kostya Trachenko of Queen Mary University of London, concerns the way fundamental physical constants constrain the viscosity and diffusion properties of liquids. In plain English, it asks why liquids such as water are fluid enough for molecules to move around in them at rates compatible with cellular life. Life is not just a matter of having carbon, hydrogen, oxygen, nitrogen and other useful atoms available. It also requires those atoms and molecules to move, interact, react and be transported inside and between cells. That means the physical properties of liquids are not incidental details; they are part of the basic physical background without which living cells could not function.

In 2020, Trachenko and colleagues showed that there is a fundamental lower limit to liquid viscosity — in other words, to how runny a liquid can be. This later paper takes that insight into biology and asks how changes in fundamental constants would affect the viscosity and diffusion rates needed for living processes. The conclusion is that there appears to be a “bio-friendly” window within which fundamental constants must fall if liquids are to have the right properties for life as we know it.

Creationism Refuted - 240 Million-Year-Old Giant Amphibian Fossil Found In A Wall

Scientists name new species of giant amphibian found in retaining wall

As a child growing up in the North Oxfordshire countryside, and already deeply interested in all things to do with nature, one of my favourite ways of looking for fossils was to search the many dry-stone walls used as field boundaries in the area. Being made largely from sedimentary limestone, they often contained fossils of ancient marine molluscs. It would probably have given a creationist nightmares to find evidence of vanished seas in a field wall, but even that is modest compared with a fossil discovered in a slab intended for use in a garden retaining wall in New South Wales, Australia.

The slab was among stones obtained in the 1990s from a local NSW quarry by a retired chicken farmer who intended to use them to build a garden retaining wall. When he spotted the fossil, however, he donated the slab to the Australian Museum in Sydney. Decades later, Australian Museum palaeontologist Lachlan J. Hart, with colleagues from the University of New South Wales and the University of Washington, Seattle, identified it as the 240-million-year-old fossil of Arenaerpeton supinatus. The fossil preserves most of the skeleton and, unusually, even shows the outline of the animal’s skin. Their formal description was published in the Journal of Vertebrate Paleontology.

Arenaerpeton supinatus, meaning ‘supine sand creeper’, inhabited freshwater rivers in what is now the Sydney Basin during the Triassic Period, around 240 million years ago. It may have been one of the top predators in that environment, hunting ancient fish such as Cleithrolepis. Superficially, it resembled the modern Chinese giant salamander, but it was more heavily built and armed with powerful teeth, including a pair of fang-like tusks in the roof of its mouth.

Warwick Study: Ancient Forests Under North Sea Lost World

More than 16,000 years ago, long before, according to their favourite Bronze Age mythology, creationists' little god created a small flat Earth under a dome centred on the Middle East, people and animals were able to walk from continental Europe into what are now the British Isles. They did so not by walking on water, but across dry land now submerged beneath the North Sea, of which Dogger Bank is one surviving remnant. From this lost landscape, Ice Age fossils such as mammoth teeth and tusks are still regularly dredged up in trawlers' nets.

Whatever hominins left the famous footprints at Happisburgh, Norfolk, almost certainly reached Britain on foot from western Europe, as did, much later, the hominins represented at Swanscombe in Kent and Pontnewydd Cave in Denbighshire, Wales.

Now, evidence presented in Proceedings of the National Academy of Sciences (PNAS) by a team led by Professor Robin G. Allaby of Warwick University's School of Life Sciences shows that southern Doggerland was not a bleak, barren wasteland but supported temperate woodland more than 16,000 years ago. The team reached this conclusion from a detailed analysis of 252 sediment samples from 41 marine cores taken along the prehistoric Southern River in southern Doggerland, where exceptionally well-preserved deposits preserve an environmental record from the Late Pleistocene into the Holocene.

For creationists, the problem is not merely the age of this drowned landscape, awkward though that is for biblical chronology. It is the existence of the evidence itself: well-preserved, datable layers laid down over vast spans of time, preserving a coherent ecological history that can be tested, checked and verified. If biblical mythology were true, those layers should not exist in anything like this form. But they do, and they tell a story utterly at odds with Genesis.

In science, evidence that contradicts a hypothesis counts against it. A theory that repeatedly fails is supposed to be revised or abandoned. Creationism works the other way round. Evidence against it is treated not as a reason to change one's mind, but as a test of faith. By that twisted logic, the more decisively reality refutes it, the more convinced its followers become that they must be right. That is not intellectual strength. It is simply a refusal to let evidence matter.

An interesting aspect to this work, and one that may upset creationists, is the fact that the team used two different, unrelated methods for dating - carbon dating and optically stimulated luminescence (OSL) dating which converged on the same dates.

Refuting Creationism - Another Gap Shrinks And It's More Bad News For Creationists

Virginia Tech researcher's team discovers 'missing' sea sponges | Virginia Tech News | Virginia Tech

Scientists have narrowed another gap in the fossil record and, as usual, no gods were found. The gap concerned the long interval between the time molecular-clock analyses suggest sponges first evolved in the Neoproterozoic, perhaps around 700 million years ago, and the earliest widely accepted sponge fossils from the early Cambrian. That gap has now been pushed back into the Late Ediacaran by Virginia Tech geobiologist a paper in Nature.

Creationists normally delight in gaps in the fossil record because they think Darwin somehow “admitted” that missing links were fatal to his theory. In reality, Darwin was doing what honest scientists do: openly acknowledging the limitations of the evidence available in 1859. The key point is that he was writing about the state of knowledge then, not in 2026. Since Darwin’s day, the Theory of Evolution has not only provided a framework for understanding the history of life; it has also told scientists what sort of evidence to look for and where to look for it. As a result, palaeontologists now have access to vastly more fossils than Darwin could ever have imagined, together with genetic evidence and radiometric dating methods that did not exist in his lifetime. More fossils are being found almost daily and invariably confirm the Theory of Evolution.

And those gaps continue to shrink, almost always to the discomfort of creationists, because they so often concern events hundreds of millions, even billions, of years before the narrow timescale allowed by biblical literalism. This fossil is especially awkward for them because it further undermines the familiar creationist misrepresentation of the Cambrian “Explosion” as a sudden, magical appearance of multiple body plans with no ancestry. Instead, this Late Ediacaran sponge adds to the growing evidence that the Cambrian diversification was preceded by a long evolutionary prelude, in which animals were already emerging and diversifying before the Cambrian began. Far from an abrupt act of creation, the picture is one of gradual evolutionary change over immense spans of time, as the largely sessile Ediacaran world gave way to the more active and ecologically complex Cambrian one.

Creationism Refuted - The Transition From Cold-Blooded to Warm-Blooded Mammal Ancestors

Mystery solved: when mammals’ ancestors became warm-blooded

If the transition from cold-bloodedness to warm-bloodedness is not a change in “kind” in the creationist sense, it is hard to imagine what would qualify. Creationists often try to dismiss major evolutionary transitions as mere “variation within a 'Kind'”, but the shift from ectothermy to endothermy was not some trivial adjustment. It was a profound physiological transformation that allowed animals to maintain a high, stable internal temperature, remain active across a wider range of conditions, and exploit ecological niches closed to their cold-blooded ancestors. Yet, according to creationist mythology, no such transition ever occurred, and there was never a point in time when it began.

Unfortunately for creationists, the evidence says otherwise. An international team of palaeontologists led by Ricardo Araújo of the Universidade de Lisboa, Lisbon, Portugal, Romain David of the Natural History Museum, London, UK, and Kenneth D. Angielczyk of the Field Museum of Natural History, Chicago, USA, believe they have identified when endothermy arose in the mammalian lineage. Their findings were published in Nature in July 2022. The team concluded that mammalian ancestors became warm-blooded about 233 million years ago, roughly 33 million years before the first true mammals appeared, and at about the same time that other recognisably mammalian traits such as fur and whiskers were evolving. The timing is consistent with evolutionary expectations that major innovations can arise in response to changing environmental pressures. [1.1]

They also concluded that this transition was rapid in geological terms, taking less than a million years rather than unfolding gradually over tens of millions of years, as had often been assumed. [2.1]

The researchers reached these conclusions by examining 3D models of the inner ears of dozens of mammalian ancestors, many from South Africa’s fossil-rich Karoo region. Karoo fossils are especially valuable because they preserve an exceptionally detailed record of synapsid evolution across almost 100 million years, documenting the transition from reptile-like therapsids to mammals. What the team focused on was the shape of the semicircular canals of the inner ear, which form part of the balance system. These canals are filled with endolymph, a fluid whose viscosity changes with temperature. As body temperature rose during the evolution of endothermy, the geometry of the canals had to change to keep the balance organ functioning properly. That gave the researchers a way to infer when warm-bloodedness first evolved in the mammalian line. [2.1]

Four of the authors of the paper in Nature also published an article in The Conversation explaining their results and their significance for understanding mammalian evolution. Their article is reproduced here under a Creative Commons licence, reformatted for stylistic consistency.

Embryo fossil found in South Africa is world’s oldest proof that mammal ancestors laid eggs

It is well established in evolutionary biology that mammals arose from within the synapsid lineage, the ancient group that includes the therapsids - stem-mammals that long predate true mammals. What had remained uncertain, however, was whether those early synapsids still reproduced by laying eggs, as modern monotremes such as the platypus and echidnas do, or whether live birth had evolved much earlier in the mammalian line.

That gap in our knowledge has now been narrowed dramatically and, no doubt to the acute discomfort of creationists, the evidence shows that about 250 million years ago - roughly 244 million years before young-Earth creationists believe the Earth was created - a therapsid was still reproducing by laying eggs. The evidence comes from a fossil embryo discovered in South Africa in 2008 by palaeontologist John Nyaphuli. Even more awkward for creationists, their mythology requires animals to have been created as separate, unrelated ‘kinds’, yet here we have direct evidence from the stem-mammal lineage showing a reproductive stage inherited from deep evolutionary ancestry rather than sudden, magical creation without predecessors.

Now Julien Benoit and Jennifer Botha of the University of the Witwatersrand, South Africa, together with Vincent Fernandez of the European Synchrotron Radiation Facility in Grenoble, France, have used high-resolution CT and synchrotron imaging to examine the curled-up embryo inside the rock and identify it as a young Lystrosaurus, a dicynodont therapsid from the Early Triassic. Crucially, the specimen preserves features consistent with an unhatched embryo, including a tightly curled in ovo posture and an unfused lower jaw symphysis. No calcified eggshell was preserved, so the egg was probably soft and leathery, as expected for a very early synapsid. Their findings are reported in an open access paper in PLOS One.

The authors have also co-authored an article in The Conversation explaining the discovery and its significance. Their article is reprinted here under a Creative Commons licence, reformatted for stylistic consistency.

Creationism Refuted - Neanderthal Cannibals From 35,000 Years Before 'Creation Week'

Neandertal women and children were the victims of selective cannibalism at Goyet | CNRS

he evidence presented in my last blog post suggested that, at least in the earlier phases of contact between anatomically modern humans moving out of Africa and the indigenous Neanderthals, interactions could be relatively peaceful, involving exchanges not only of DNA but also of technology and culture.

That may not always have been the case, however, as new evidence from the Troisième caverne of Goyet in Belgium suggests. Research just published in Scientific Reports by an international team including researchers from CNRS, the University of Bordeaux, and Aix-Marseille University indicates that, between 41,000 and 45,000 years ago, when Neanderthals were close to disappearing from Western Europe, a group consisting largely of non-local females and juveniles was taken to the Goyet site, butchered, and consumed. The broader background to this violence may have included growing territorial pressures, dwindling populations, or the increasing presence of Homo sapiens in nearby regions, but the precise cause remains unknown.

So, while we cannot know exactly what triggered this episode, and while the coincidence with the arrival of Homo sapiens may or may not be significant, isotope analysis does show that those who were cannibalised were outsiders rather than members of the local population.

For creationists, Neanderthals have always been a problem. It used to be common for them to claim that Neanderthals were known from just a single specimen later shown to be a pathological modern human suffering from arthritis. That falsehood has become harder and harder to sustain now that we have numerous specimens from across Eurasia, as well as sequenced Neanderthal genomes. The fallback position now seems to be to insist that Neanderthals fit neatly into Genesis because they were simply part of “human kind”.

Ken Ham, the creationist head of Answers in Genesis, with his characteristically casual regard for the truth and his obvious personal stake in presenting Bible-literalist mythology as history and science, has recently claimed that Neanderthals and Denisovans were descendants of Adam and Eve. What he does not explain, of course, is how he compresses the archaeological timescale of their existence, and their divergence into distinct lineages with markedly different genomes, into the 6,000 to 10,000 years allowed by creationist dogma. Like so many of Ham’s claims, it is aimed at an audience eager to have its prejudices confirmed and unlikely to fact-check anything for fear of discovering that it has been misled.

Like so much else in the history of life on Earth, and especially in the evolutionary history of our own species, all of this took place in that immense span of time before creationists imagine their small tribal god conjured up a small flat planet under a solid dome, conveniently centred on the Middle East.

The factual evidence, of course, tells a very different story: one based on testable, verifiable data, not on the campfire tales of Bronze Age herders who knew no better.

And in this case, that evidence shows that something, whether the increasing presence of modern Homo sapiens, the breakdown of Neanderthal society as their numbers declined, or some other factor entirely, led one Neanderthal group in what is now Belgium to capture outsiders, mainly women and children, bring them back to the Goyet site, and consume them.

Canine companions: revealing the genetic history of our first friends | Crick

This is the second of my posts on the domestication of dogs and on why the facts are so awkward for creationists. It concerns research by a team led by Anders Bergström and Pontus Skoglund of the Francis Crick Institute, London, working with colleagues from the Max Planck Institute for Evolutionary Anthropology and a large international network of collaborators.

The team have shown that the domestication of dogs had already begun well before the invention of farming, when humans in Europe still lived in nomadic bands of hunter-gatherers. At that stage, dogs would have been hunting companions, sentinel guards for encampments, and perhaps even family pets, long before they were adapted for the many tasks later associated with farming, such as herding livestock and guarding flocks. Their findings are published in Nature.

This establishes dogs as the first domestic animals and suggests that the human-dog relationship may have helped lay the groundwork for later animal husbandry and selective breeding.

The story of the domestication of dogs from wolves is something in which I have long taken a special interest, and it was that interest which led me to write two books with fictionalised accounts of how it may have happened - The Girl and the Wolf and its sequel, The Way of the Wolf: A Stone Age Epic.

Biologically, of course, this evolved symbiotic relationship between two species is exactly the sort of outcome the Theory of Evolution leads us to expect. But, embarrassingly for creationists, it also tells a story rooted in deep time, for which creationism has no credible explanation. Worse still for biblical literalists, it makes a mockery of the claim that God created all animals for the benefit of humankind, because that claim presupposes that animals created by an omniscient, omnipotent designer would already be fit for purpose and would not need extensive modification by human selective breeding.

The researchers reached their conclusions by analysing DNA from 216 canid skeletal remains, including 181 pre-Neolithic samples - that is, from before approximately 10,000 years ago. These remains came from sites across Europe and nearby regions, including Switzerland, Germany, Belgium, the Netherlands, Turkey, Sweden, Denmark and Scotland.

Creationists previously had a little wriggle room when the earliest indisputable domestic dog was thought to date to about 10,900 years ago. They could at least pretend that dogs appeared during their imaginary ‘Creation Week’ or shortly afterwards. That pretence is now no longer sustainable. This study shows that the ancestry of later dogs was already established before 14,200 years ago, and probably earlier still.

Malevolent Design - How Epigenetics Helps Pancreatic Cancer To Spread

Growth of Spreading Pancreatic Cancer Fueled By “Under-Appreciated” Epigenetic Changes | Johns Hopkins Medicine

A new paper in Molecular Cancer from Johns Hopkins Medicine describes yet another discovery that should be deeply uncomfortable for Intelligent Design creationists. The researchers found that the spread of pancreatic cancer is driven not chiefly by fresh mutations in DNA sequence, but by epigenetic reprogramming — changes in chromatin organisation and gene activity. In particular, they identified KLF5 as a major driver of metastatic growth, with higher expression in most metastatic lesions than in the matched primary tumours. The paper in Molecular Cancer shows that KLF5 promotes metastatic proliferation through epigenetic modifier genes including NCAPD2 and MTHFD1, helping switch on programmes involved in migration, plasticity and invasion. [1]

What makes this especially important is that epigenetics is not some magical extra layer of “specified information” inserted into life by a supernatural designer. Its roots are ancient. In bacteria, DNA methylation is a major form of epigenetic regulation, involved in gene expression, chromosome replication and DNA repair. In archaea, histone-based chromatin already exists in a form strikingly similar to that of eukaryotes, and studies show that chromatin architecture and its role in regulating gene expression long predate complex multicellular life. In other words, the basic machinery was already there in simpler organisms, doing ordinary cellular housekeeping long before animals and plants ever appeared. [2]

Multicellular organisms did not receive a brand-new control system from an intelligent agent; they inherited this ancient molecular toolkit and elaborated it. As multicellularity evolved, epigenetic regulation expanded and became central to cell differentiation, allowing cells with the same DNA to adopt different stable identities by opening some regions of the genome and closing others. Work on the transition from unicellular to multicellular states in Dictyostelium, for example, shows that chromatin reorganisation and histone modifications are closely tied to the shift into multicellularity, while evolutionary reviews note that epigenetic diversity expanded rapidly with multicellular life and that epigenetic marks are crucial in development and long-lived cell lineages. [3]

And that is exactly why this Johns Hopkins work is such bad news for ID creationists. The same ancient, repurposed system that multicellular organisms rely on for cell specialisation can also be subverted to drive one of the deadliest features of cancer: metastasis. That is what evolved systems do. They are modified from older parts, good enough to work, but never perfect and never immune to catastrophic failure. What this study reveals is not elegant, flawless engineering, but the vulnerability of a historically evolved regulatory system — one that natural selection adapted for development and tissue specialisation, but which disease can hijack with lethal consequences. That is entirely consistent with evolution, and profoundly at odds with the notion of a competent, benevolent designer. [1]

Oldest octopus fossil is no octopus at all scans reveal - University of Reading

The excitement creationists may feel on hearing that science has got it wrong yet again because a fossil once classified as the oldest known octopus has now been reidentified, will no doubt be tempered by the awkward fact that the animal it really belonged to lived 300 million years before, according to their beliefs, there was even a universe, let alone life on Earth. As so often, the truth poses no problem for science; it is creationism that stumbles over it.

Far from showing that science is unreliable compared with the supposed ‘eternal truth’ of religion, this revision is a vindication of the scientific method and a demonstration of its self-correcting nature. Unlike religions, which cling to ‘sacred truths’ that, when tested against reality, turn out to be little more than the best guesses and campfire tales of our ignorant and fearful ancestors, science is a method for moving ever closer to the truth. It remains the best tool we have for discovering reality precisely because nothing is sacred except truth itself, and because scientific understanding is always provisional — open to revision whenever new evidence demands it, unlike religions which are doxastically and doctrinally closed to new information.

On this occasion, the fossil re-examined and found not to be what it was once thought to be was the famous Pohlsepia mazonensis, identified as an octopus 25 years ago and even entered in the Guinness Book of Records as the oldest known fossil octopus. Using modern synchrotron imaging to peer inside the fossil and reveal details the original investigators could not see, researchers discovered tiny teeth and other internal features showing that it was not an octopus at all, but a nautiloid — a cephalopod with an external shell. The team recently published their findings in the journal Proceedings of The Royal Society B.

Our modern vision evolved from an ancient one-eyed worm creature

A recently published paper in the Cell Press journal, Current Biology, by four palaeontologists — two from the University of Sussex, UK, and two from Lund University, Sweden — delivers yet another solid rebuttal to creationist misrepresentation. It traces the origin of the vertebrate eye back to a worm-like marine creature that lived around 600 million years ago, neatly demolishing the old creationist claim that something as complex as the eye could never have evolved by natural means.

One of the favourite dishonest tricks in the creationist repertoire is the quote mine: lifting a sentence from an expert, stripping it of context, and presenting it as though it supports the very position the author was arguing against. Few examples are more shameless than their abuse of a passage from Darwin's On the Origin of Species. In typical Darwinian style, he first states what appears to be a serious objection to his theory, then immediately explains why it is not a real objection at all. The part creationists love to quote, from page 100, is this:

To suppose that the eye, with all its inimitable contrivances for adjusting the focus to different distances, for admitting different amounts of light, and for the correction of spherical and chromatic aberration, could have been formed by natural selection, seems, I freely confess, absurd in the highest possible degree.

Presented on its own, this is supposed to fool the unwary into thinking Darwin admitted defeat — as though he had conceded that evolution could not explain the eye and that modern creationists were right all along with their talk of 'irreducible complexity'. But, as usual, the deception depends entirely on stopping before the very next sentence, where Darwin wrote:

AI-Generated Image (ChatGPT Latest)

Yet reason tells me, that if numerous gradations from a perfect and complex eye to one very imperfect and simple, each grade being useful to its possessor, can be shown to exist; if further, the eye does vary ever so slightly, and the variations be inherited, which is certainly the case; and if any variation or modification in the organ be ever useful to an animal under changing conditions of life, then the difficulty of believing that a perfect and complex eye could be formed by natural selection, though insuperable by our imagination, can hardly be considered real.

Charles Darwin, On the Origin of Species By Means of Natural Selection, or, the Preservation of Favoured Races in the Struggle for Life (p. 100). Public Domain Books. Kindle Edition.

So Darwin was not conceding the point at all; he was doing the exact opposite. He was saying that the apparent absurdity disappears once we recognise that useful intermediate stages can and do exist. In other words, the creationist quote mine works only by concealing Darwin's actual argument.

And now, more than 160 years later, the evidence Darwin lacked has arrived in abundance. He could not have known the developmental genetics, the comparative anatomy, the fossil evidence, or the evolutionary history that modern biology has uncovered. Creationists have no such excuse. They are not merely repeating an old objection; they are repeating one that has been answered again and again, and now answered yet again by evidence tracing the deep evolutionary roots of the vertebrate eye itself.

So this discovery matters not simply because it adds another detail to the history of life, but because it exposes the intellectual bankruptcy of the creationist argument. The eye is not a problem for evolution. It is a triumph of evolution — a structure whose history is precisely the sort of gradual, functional modification Darwin predicted. The real problem lies not with evolutionary theory, but with those who continue to misquote Darwin and mislead their audiences in the hope that no one will bother to read past the sentence they have carefully amputated from its context.

An account of how the researchers arrived at their conclusion is given in an article in The Conversation by two of the four scientists involved. Their article is reproduced below under a Creative Commons licence, reformatted for stylistic consistency:

Spectacular fossil treasure trove pushes back origins of complex animals | University of Oxford

A paper just published in Science by a team of palaeontologists from Oxford and Yunnan universities should, if creationists were honest enough and sufficiently knowledgeable to understand it, finally lay to rest two favourite canards they use to attack Darwinian evolution: the so-called Cambrian Explosion and their misrepresentation of Stephen Jay Gould’s idea of punctuated equilibrium.

The Cambrian Explosion is a favourite target for creationists, who exploit the word “explosion” to misrepresent it as the sudden appearance of multicellular life with multiple body plans, supposedly without ancestry, and therefore as a single act of supernatural creation. The fact that it happened some 535 million years ago is usually dismissed with the standard creationist repertoire: claims that scientists are inventing the dates, relying on “flawed” dating techniques, or, more bizarrely still, failing to take account of some unspecified change in radioactive decay rates that just happens to make 6,000–10,000 years look like 535 million.

But that fallacy was based on very limited data, especially the fossils from the Burgess Shale, which provided only a narrow snapshot of living organisms at one time and place. From evidence such as this, Stephen Jay Gould and Niles Eldredge developed the idea of punctuated equilibrium, in which long periods of relative stasis in the fossil record are interrupted by comparatively short episodes of more rapid evolutionary change. Creationists eagerly seized on this, dishonestly presenting it as though Gould had somehow replaced Darwinism and proved Darwin wrong. In reality, it did no such thing. It was not a rejection of evolution, nor of common descent, nor of natural selection, but a discussion within evolutionary biology about the pattern and tempo with which evolutionary change appears in the fossil record.

Darwin, of course, never claimed that evolution must proceed at a constant, steady rate. On the contrary, his theory makes it clear that changing environments drive evolutionary change, so more rapid evolution during periods of environmental upheaval is entirely consistent with Darwinian evolution and, indeed, a vindication of it. The appearance of long stasis followed by apparently abrupt change can also be exaggerated by the incompleteness of the geological record, in which spans of thousands of years may appear almost instantaneous when compressed into a thin layer of rock.

However, the notion that the Cambrian Explosion was a sudden event without ancestry has been steadily dismantled by discoveries pushing the origins of Cambrian-type biota back towards the Ediacaran, together with evidence that some Ediacaran organisms were already capable of movement. What emerges is not a miraculous burst of creation, but a clear evolutionary progression from the Ediacaran into the Cambrian.

Now this new paper strengthens that case by showing that complex body plans existed much earlier than previously thought, and by presenting evidence of gradual Darwinian evolution from the Ediacaran into the Cambrian.

The evidence comes from a treasure trove of fossils, the Jiangchuan Biota in Yunnan Province, southwest China, where more than 700 fossil specimens were recovered from rocks dated to between 554 and 539 million years old. Among the more surprising finds is a deuterostome — part of the broad group that includes vertebrates such as fish and humans.

A 500-Million-Year-Old Clawed Predator Rewrites the Origin of Spiders and Horseshoe Crabs | Department of Organismic and Evolutionary Biology

Another day, another piece of evidence for creationists to ignore, misrepresent or simply lie about — anything, in fact, except honestly acknowledge that it shows they are wrong. This discovery strikes at the heart of creationism. It not only refutes the notion that Earth is just 6,000–10,000 years old, but also demolishes two favourite creationist misrepresentations: that there are no transitional fossils, and that the Cambrian Explosion was some sudden, magical appearance of multiple body plans with no evolutionary ancestry. Of course, creationists can always fall back on the familiar claim that scientists invented the dates to lure people away from God and convert them to “Darwinism”.

The evidence, published in Nature, is a 500-million-year-old transitional fossil showing that arthropods had already diverged to produce the chelicerate subphylum — the lineage that would eventually give rise to spiders, scorpions and horseshoe crabs. This pushes the earliest known chelicerates back by some 20 million years from the previous oldest example, dated to about 480 million years ago from the Early Ordovician Fezouata Biota of Morocco.

The crucial evidence was the presence of the defining chelicerae, identified by research scientist Rudy Lerosey-Aubril of Harvard University while microscopically cleaning a fossil arthropod that the scientists have named Megachelicerax cousteaui. Chelicerae are the pincer-like, sometimes venomous, foremost appendages that define chelicerates, in contrast to the antennae that are the foremost appendages in insects and many other arthropods.

This shows that chelicerae evolved before chelicerates acquired their later, more familiar body plan with a two-part body and the reduced head appendages that became the eight walking legs of spiders and their relatives. In other words, this fossil captures an intermediate stage between the earlier, multi-segmented arthropods and the later chelicerate body plan. It is, therefore, precisely the sort of transitional form creationists keep claiming does not exist — right up until one is found, at which point they are forced to deny, distort or ignore it.

Refuting Creationism - How New Genetic Information Can Arise Rapidly, Naturally

How ‘supergenes’ help fish evolve into new species | University of Cambridge

Creationists like William A. Dembski constantly reassure their fellow believers that new genetic information cannot arise naturally and therefore requires divine intervention. This claim depends on a misrepresentation of the laws of thermodynamics and a deliberate confusion of information with energy. It is clung to despite the obvious and overwhelming evidence to the contrary, with the same tenacity that creationists bring to their insistence that evolution either does not happen at all or, if it does, must somehow have occurred at an impossibly rapid rate after the Flood to produce such enormous variation within their invented ‘kinds’ from just a single surviving pair.

So now we have yet more contrary evidence for creationists to ignore, this time in the form of an explanation for how the cichlid fishes of Lake Malawi in East Africa were able to evolve into more than 800 species in a fraction of the time it took humans and chimpanzees to diverge from a common ancestor. Readers of this blog with long memories may recall that, back in 2012, I described these fish as a particularly powerful argument against creationism.

The fact of this rapid adaptive radiation, taking place on a timescale that could be independently verified, was already indisputable. What we lacked at the time was a clear understanding of the underlying mechanism that made it possible. That gap has now been filled by researchers from the Universities of Cambridge and Antwerp, who have shown that the source of this new genetic information lies in genetic inversions, where an entire section of DNA is inserted in reverse orientation. They have recently published their findings in the journal Science.

During the normal process of meiosis, in which reproductive cells are formed, crossing-over reshuffles genes to produce new combinations in offspring. But when a segment of DNA has been inverted, that section cannot take part properly in the crossing-over process. As a result, the genes within it remain linked together as an intact block, forming what geneticists call a ‘supergene’. These supergenes can then be inherited largely unchanged across generations. The effect is to create barriers to hybridisation much more quickly than would otherwise be possible, effectively isolating a new gene pool within the wider population and allowing new species to evolve far more rapidly than usual, instead of having novel gene combinations continually diluted by interbreeding across the whole population.
