A recent re-examination of museum coelacanth fossils has shown that there was more than one taxon in the Late Triassic and that, where we believed there were just four specimens, there are actually more than fifty. These fossils were hiding in plain sight, mis-identified for decades in collections across Britain. This significantly expands the known diversity of coelacanths at that time and neatly illustrates how science continually refines and improves its understanding as new evidence and careful re-analysis emerge.
Coelacanths have long been a favourite talking-point for creationists, who seized on the 1938 discovery of living Latimeria — a lineage once known only from the fossil record and thought extinct — as supposed proof that evolution had somehow stalled. Because the modern species still carries the name “coelacanth”, they leap to the assumption that the fish has remained unchanged for over 200 million years, and therefore evolution must be false. I have even seen creationists claim that if coelacanths have “not evolved” in all that time, the Earth must therefore be only a few thousand years old. It’s an extraordinary logical contortion — and one born of misunderstanding both biology and evidence.
In reality, the modern coelacanth is not the same species as the ancient Triassic forms, nor is evolutionary change required to be dramatic or constant for every lineage. Species can remain broadly similar when their ecological niche remains stable — a concept perfectly consistent with evolutionary theory. What this study demonstrates, once again, is the iterative, self-correcting nature of science: questions are never closed, evidence is always open to re-examination, and conclusions adapt as new data emerges.
Human evolution isn’t a tidy staircase; it’s a branching, tangled tree full of transitional forms. And now, cutting-edge protein analysis from two-million-year-old teeth has revealed that Paranthropus robustus — one of our distant cousins — carried mixed ancestry, adding powerful new evidence to the evolutionary story creationists work so hard to deny.
If there is anything guaranteed to send a creationist into a fit of denial — desperately trying to redefine basic terms such as “transitional”, “species”, and “evolution”, and, as a last resort, claiming palaeontologists must have faked the evidence — it is the discovery of a transitional species in human evolutionary history.
But the hominin fossil record, like the evolutionary record for most living species, is absolutely packed with transitional forms. In fact, there are so many in human palaeontology that it can be difficult to single out one that is clearly more ‘transitional’ than the rest, because they form a fairly smooth continuum from the australopiths through to the genus Homo, just as we would expect of a slow process unfolding over tens of thousands or millions of years.
However, one species, Paranthropus robustus, stands out for its mosaic of features consistent with a lineage intermediate between the common ancestor of chimpanzees and hominins and the australopiths that followed.
And this mosaic has now been expanded to include genetic-level evidence, thanks to advances in palaeoproteomics. Proteins can persist far longer than DNA, yet they retain a direct correspondence to DNA via RNA, which encodes their amino-acid sequences. Once ancient proteins have been recovered and analysed, researchers can work backwards to reconstruct the RNA, and therefore the DNA, that produced them.
Using proteins extracted from the tooth enamel of four P. robustus fossils, researchers led by the University of Copenhagen have shown that these individuals themselves had mixed ancestry — indicating interbreeding with contemporaneous relatives, just as we now know happened among later hominin species, and almost certainly among the australopiths too.
For nearly a century, scientists have been puzzling over fossils from a strange and robust-looking distant relative of early humans: Paranthropus robustus. It walked upright, and was built for heavy chewing with relatively massive jaws, and huge teeth with thick dental enamel. It’s thought to have lived between 2.25 million and 1.7 million years ago.
Fossils show how these early relatives evolved from as far back as A. africanus, 3.67 million years ago. They also document milestones in evolution, including the transition to walking on two legs, tool making and increased brain development. Ultimately, our species – Homo sapiens – appeared in South Africa 153,000 years ago.
Fossils of P. robustus were first discovered in South Africa in 1938. But crucial questions remained. How much variation was there within the species? Were the size differences related to sex, or did they reflect the presence of multiple species? How was P. robustus related to the other hominins and early Homo? And what, genetically, made it distinct?
Until now, answers to these questions have been elusive. As a team of African and European molecular science, chemistry and palaeoanthropology researchers, we wanted to find answers but we couldn’t use ancient DNA to help us. Ancient DNA has been a game-changer in studying later hominins like Neanderthals and Denisovans but it doesn’t survive well in Africa’s climate because of its simple structure.
We experienced a breakthrough when we decided to use palaeoproteomics – the analysis of ancient proteins. We extracted these from the enamel of the 2-million-year-old teeth of four P. robustus fossils from Swartkrans Cave in South Africa’s Cradle of Humankind.
Luckily, proteins that are millions of years old preserve well because they stick to teeth and bones and are not affected by the warm weather. One of these proteins tells us the biological sex of the fossils. This is how we found that two of the individuals were male and two were female.
These findings open a new window into human evolution – one that could reshape how we interpret diversity in our early ancestors by providing some of the oldest human genetic data from Africa. From there, we can understand more about the relationships between the individuals and potentially even whether the fossils come from different species.
More than one kind of Paranthropus?
The protein sequences also revealed other subtle but potentially significant genetic differences. One standout difference was found in a gene which makes enamelin, a critical enamel-forming protein. We found that two of the individuals shared an amino acid with modern and early humans, chimpanzees and gorillas. The other two had an amino acid that among African great apes is, so far, unique to Paranthropus.
What’s even more interesting is that one of the individuals had both the distinct amino acids. This is the first documented time we can show heterozygosity (a state of having two different versions of a gene) in proteins that are 2 million years old.
When studying proteins, specific mutations are thought to indicate different species. We were quite surprised to discover that what we initially thought was a mutation unique to Paranthropus robustus was actually variable within that group – some individuals had it while others did not. Again, this was the first time anyone had observed a protein mutation in ancient proteins (these mutations are usually observed in ancient DNA).
We realised that instead of seeing a single, variable species, we might be looking at a complex evolutionary puzzle of individuals with different ancestries. This shows that combining analyses of morphology (the study of the form and structure of organisms) and the study of ancient proteins, we can create a clearer evolutionary picture of the relationships among these early hominin individuals.
However, to confirm that P. robustus fossils have different ancestry, we will need to take samples of tooth enamel protein from more of their teeth. To do this, we plan to sustainably sample more P. robustus from other sites in South Africa where they’ve been found.
Preserving Africa’s fossil heritage
Our team was careful to balance scientific innovation with the need to protect irreplaceable heritage. Fossils were sampled minimally, and all work followed South African regulations. We also involved local laboratories in the analysis. Many of the authors were from the African continent. They were instrumental in guiding the research agenda and approach from the early stages of the project.
Doing this kind of high-end science on African fossils in Africa is an important step towards transformation and decolonisation of palaeontology. It builds local capacity and ensures that discoveries benefit the regions from which the fossils come.
By combining data on molecules and morphology, our study offers a blueprint for future research – one that could clarify whether early hominins were more or less diverse than we’ve known.
For now, the Paranthropus puzzle just got a little more complex – and a lot more exciting. As palaeoproteomic techniques improve and more fossils are analysed, we can expect more surprises from our ancient relatives.

Abstract
Paranthropus robustus is a morphologically well-documented Early Pleistocene hominin species from southern Africa with no genetic evidence reported so far. In this work, we describe the mass spectrometric sequencing of enamel peptides from four ~2 million–year-old dental specimens attributed morphologically to P. robustus from the site of Swartkrans in South Africa. The identification of AMELY-specific peptides enabled us to assign two specimens to male individuals, whereas semiquantitative mass spectrometric data analysis attributed the other two to females. A single amino acid polymorphism and the enamel-dentine junction shape variation indicated potential subgroups present within southern African Paranthropus. This study demonstrates how palaeoproteomics can help distinguish sexual dimorphism from other sources of variation in African Early Pleistocene hominins.
Once again, the evidence aligns from every direction: anatomy, geology, developmental biology, genetics, and now ancient proteins all tell the same story. Human evolution is a messy, branching, experimentally rich process — and *Paranthropus robustus* sits right where we would expect a transitional form to sit, complete with the genetic fingerprints of interbreeding and divergence.
Creationists often demand “transitional forms” as though evolution should be obliged to produce museum-ready half-and-half creatures on command. Yet when the fossil record delivers precisely what any honest inquirer would recognise as transitional, the response is denial, distortion, and conspiracy theories about forged fossils. It is not evidence they lack; it is the willingness to accept it.
Science advances not by clinging to comforting myths, but by following data wherever it leads. And as our tools improve — from classical morphology to whole-genome sequencing and now ancient protein reconstruction — the picture of human origins becomes richer, more detailed, and entirely consistent with evolution by natural processes. The real story of our species is far more fascinating than any manufactured pseudoscience: we are the product of deep time, branching ancestries, and countless experiments in survival — a lineage written in bone and now, quite literally, in protein.

This, the second paper, published in 2022 that utterly refutes creationism on several different levels, reports evidence that particularly undermines their claim that an omnibenevolent god created a world fine-tuned for life.
This belief arises from a deeply ignorant, rose-tinted view of the world — one that conveniently ignores history and habitually attributes anything bad to something else: sin, free will, or other theological constructs that, by their own narrative, could only have applied after some supposed “fall”.
In reality, even a superficial understanding of Earth’s history — 99.9975 % of which took place before creationism’s legendary “Creation Week” — reveals that the planet is anything but fine-tuned for life. Life on Earth has repeatedly been subjected to mass extinctions triggered by geological and cosmological catastrophes that wreaked havoc on the environment, often at a pace too rapid for most species to adapt.
One of the most famous of these events was the meteor impact in what is now the Yucatán Peninsula, 66 million years ago. This strike plunged the planet into a “nuclear winter” as atmospheric dust blotted out the Sun. Within weeks, almost all large species were exterminated, leaving only the avian dinosaurs — likely shielded by insulating feathers — and early mammals, protected by their insulating fur.
But as this recent paper shows, the dinosaurs were thriving in a healthy, biodiverse environment in which they were the dominant species right up until the moment the meteor struck. Had they shared the creationists’ mindset, they might well have concluded that Earth was “fine-tuned” for them too.
The evidence for this comes from an international team of palaeontologists and ecologists, including researchers from University of Oulu (Finland), Universidade de Vigo (Spain), University of Washington (Seattle, USA), University College London (UK), New Mexico Museum of Natural History and Science (USA), and University of Edinburgh (UK).
Two new papers announced today will have creationists scratching their heads as they try to decide which technique for dismissing them will meet with the most approval from their fellow cultists.
The first, in Nature, concerns yet another of those supposedly non-existent transitional fossils which, because Charles Darwin predicted they would be found, must be dismissed at all costs. It comes in the form of an 86-million-year-old dinosaur fossil from Mongolia that is intermediate between the small, fleet-footed predatory dinosaurs and the larger apex predators — the tyrannosaurs.
The usual creationist response is to declare that these intermediate fossils are “not transitional; they are fully formed, created species.” Of course, that doesn’t explain why species that are intermediate between ancestral and descendant species show a mosaic of features from both. Presumably, given their parody of evolution — in which evolution is imagined as a single event where one species suddenly turns into another — they expect an intermediate to be half one and half the other: the equivalent of the “crocoduck” or a chimpanzee with a human head. In reality, this discovery shows exactly what we would expect from the fossil record of tyrannosaur evolution 86 million years ago.
It's also important to creationism that the so-called 'missing link' stays missing. It is only ever referred to in the singular and refers to some supposed link between apes and humans, and it is definitely not one of the many archaic African hominins. But of course, every fossil is the 'link' or transitional form between its parents and its offspring because evolution is a process, not the parody event of creationism, evolving species form a continuum, and this discovery from Mongolia is no exception.
Details of the surface of two sheet-like colonies of the ‘Berenicea’ type: (A) In Hyporosopora dilatata, the colony surface is relatively flat, save for the slightly convex zooids and faint growth lines (Upper Callovian or Lower Oxfordian, Oxford Clay; Stanton Harcourt, Oxfordshire); and (B) Well-defined transverse ridges cross the colony surface in Rugosopora enstonensis (Bathonian, Hampen Marly Beds; Enstone, Oxfordshire). Scale bars are 500µm.
The discovery that a group of organisms has, contrary to “Cope’s Rule,” undergone a steady reduction in body size over the past 200 million years is a useful reminder of how science works — and why religion so often falters.
A cornerstone of the scientific method is its willingness to acknowledge error. Real intellectual strength lies not in clinging to discredited beliefs as though doing so were a test of character, but in facing up to mistakes, learning from them, and changing one’s mind. That is how knowledge advances.
Religion, by contrast, remains shackled to the dogmas of its ancient founders. To alter those fundamental beliefs is, in effect, to abandon the religion itself. This is why, while science has sent probes into deep space and placed human beings on the Moon, faith — despite lofty claims of being able to “move mountains” — has yet to lift so much as a feather a millimetre off the ground.
The new finding was just reported in the journal Palaeontology by Associate Professor MA Junye of the Nanjing Institute of Geology and Paleontology at the Chinese Academy of Sciences (NIGPAS) and collaborators. They found that Berenicea, a genus of cyclostome bryozoans, has experienced a continuous reduction in zooid size over the past 200 million years. This runs counter to “Cope’s Rule,” which describes a tendency for body size to increase during the evolution of many lineages.
Cope’s Rule was formulated by the American palaeontologist Edward Drinker Cope (1840–1897). There are, of course, well-known exceptions — such as the “island effect,” where animals isolated on small islands often evolve into miniature versions of their mainland relatives — but these are localised adaptations to particular environments. Cope’s Rule, by contrast, applies to long-term, broad-scale evolutionary trends.

Apart from the fact that this fossil is a million years old, there is nothing in this discovery that creationists will struggle to dismiss with one of their well-worn stock phrases — “It was just a bird ‘kind’,” “It wasn’t transitional,” and so on. This is despite the fact that their Bible is remarkably vague about how many bird ‘kinds’ there were, includes bats as birds, and says absolutely nothing about anything outside a few square miles of the Middle East.
And of course, the date — like the entire fossil record — will be casually brushed aside as forged, fabricated, or “wrongly dated using proven false carbon dating” [sic].
But to anyone who actually values evidence and truth, and is not intent on proving their strength by clinging to demonstrably false beliefs in defiance of all contrary evidence, this find is genuinely fascinating. It provides strong evidence that the bowerbirds, today confined to Australia and New Guinea, were once far more widespread. This conclusion is based on the fact that the fossil was discovered in New Zealand. It is also suggested that climate change may have brought about its extinction in New Zealand and driven the bowerbirds' range back to its present distribution.
The discovery is reported in the journal Historical Biology by researchers from University of Cambridge, University of Otago, and Museum of New Zealand Te Papa Tongarewa. A [news release from the University of Otago]() explains the significance of the find and four of the authors have also written an article about the find in The Conversation. Their article is reprinted here under a Creative Commons licence, reformatted for stylistic consistency.
In a striking example of how science, in contrast to creationism, starts from the evidence and builds understanding accordingly, a newly discovered fossil fly has led scientists to revise their view on a seemingly minor detail of insect evolution.
Creationism, by contrast, starts with the conclusion and either distorts the evidence or ignores it altogether when, as is usually the case, it contradicts what they believe. To a creationist, the belief is sacred, so facts must comply—or be disregarded.
In my last blog post, I explained how psychologists view this behaviour as a perceived test of strength: creationists see challenges to their beliefs as threats that would make them appear weak if they accepted and adapted to the evidence. They respond by setting their faces like flint against any contradiction.
Science, by contrast, sees a refusal to change one’s mind when the evidence demands it as a mark of intellectual dishonesty. A willingness to revise one’s views shows a desirable strength of character — the hallmark of a good scientist. To a scientist, facts are sacred; opinions must flow from them. In any scientific debate, facts are neutral.
The discovery in question involves a Jurassic fossil midge from Australia — Telmatomyia talbragarica, the oldest known member of the Chironomidae (non-biting midge) family in the Southern Hemisphere. The fossil shows a mechanism for attaching to rocks using suction pads on its feet. This trait was previously thought to have evolved in marine species, but this insect lived in freshwater. That detail suggests the family did not originate in Siberia, as once believed, but in Gondwana before it broke apart.
Not the most dramatic scientific breakthrough, perhaps, but this is precisely how science advances — especially evolutionary biology: one careful step at a time, with constant re-examination and revision as new evidence emerges. It’s like working on a million-piece jigsaw puzzle without a picture on the box.
Oxfordshire, where I was born and spent the first twenty-odd years of my life, is steeped in fossil history. Notably, the lower jaw of the very first named dinosaur — Megalosaurus bucklandii — was discovered in Stonesfield, in the quaintly named valley, Bag's Bottom, the centre of the former Stonesfield slate industry, just about a mile and a half from my childhood home in the hamlet of Fawler.
About 166 million years ago, in the Middle Jurassic, much of the region now known as Oxfordshire lay under a warm, shallow sea. A sandbar separated it from the open ocean, forming a tranquil lagoon. Sediment slowly accumulated, forming limestone that preserved innumerable small molluscs. Even today, you can spot their fossilised shells in the drystone walls built from that same limestone — a subtle but constant reminder of deep time.
When I was a teenager, I would take the grandsons of the renowned palaeoanthropologist and former President of the Royal Society, Sir Wilfrid Le Gros Clark, on fossil-hunting excursions. One disused quarry, rich in fossil mussels, coiled snails and bivalves, became a familiar haunt. But nothing we ever uncovered then compares to what has just been unearthed at Dewars Farm Quarry, between Middleton Stoney and Ardley. Dubbed the “Oxfordshire Dinosaur Highway,” this newly announced discovery appears to be the longest dinosaur trackway known in Europe, at 220 metres.
The work was conducted by a team of palaeontologists co-led by Oxford University Museum of Natural History (OUMNH) and The University of Birmingham. Unsurprisingly, this find challenges certain creationist narratives and casually refuted the Bible creation myth. The announcement was recently made in an Oxford University news release.
News that an international research team led by University of Potsdam and Reiss-Engelhorn-Museen Mannheim, working with Curt-Engelhorn-Zentrum Archäometrie, has produced evidence that hippos lived along the Rhine in what is now Germany some 21,000 years before creationists believe Earth was created out of nothing, will probably come as no surprise to creationists.
They are well-practised at living in a world where verifiable evidence repeatedly refutes their beliefs. Over time, they have developed all manner of convoluted mental gymnastics to cope with the resultant cognitive dissonance—secure in the arrogant conviction that their beliefs trump evidence simply because they label them “faith”.
Normal people, of course, tend to have the humility to accept that evidence is the only valid basis for an informed opinion, and that it must therefore take precedence over myths and fairy tales told to them by parents and authority figures with vested cultural interests. The real test of whether a belief is right or wrong is how well it is supported by evidence—not how cleverly the evidence can be ignored.
This discovery extends our knowledge of the extinction timeline of European hippos, previously believed to have disappeared around 115,000 years ago. The new evidence pushes that date forward dramatically, showing that they survived until about 31,000 years ago, at least in that part of Europe. It also clarifies how these European populations were related to the African hippos.
That timeline is not only inconvenient for creationists; it also highlights the parochial nature of the Bible’s authors, who clearly had no knowledge of flora and fauna beyond their narrow Middle Eastern world. Notably, the Bible makes no mention of the African megafauna—hippos, elephants, giraffes, or ostriches, for example. In fact, the latter would have posed a serious problem for their primitive taxonomy, which classified bats as “birds” simply because they could fly. One can only wonder where they might have placed the flightless ostrich.
A phrase much loved by journalists (and creationists) is “the history/science books will need to be re-written”. It’s a convenient bit of lazy journalistic rhetoric — but in this case, the book that actually needs to be re-written is the Bible.
The discovery in question concerns the migration of early Homo sapiens, who may have spread from the Levant across Asia Minor (modern-day Türkiye) and then into Greece via a northern Aegean land bridge, exposed when sea levels were much lower during the last Ice Age — between 115,000 and 11,700 years ago.
This new evidence challenges some existing models of early human migration routes. However, it represents only a refinement of the broader, well-established story of humanity’s dispersal out of Africa, not a challenge to it. What it does completely undermine, however, is the Biblical narrative claiming that all humans descended from a single, ahistorical couple created without ancestors some 6,000 to 10,000 years ago — followed by a supposed global “reset” just 4,000 years ago when a genocidal flood left only eight related survivors.
The evidence for this Ice Age land bridge comes from the recovery of 138 stone tools at ten sites within a 200 km² area around Ayvalık in north-west Türkiye, opposite the Greek island of Lesbos.
A rich source of amber from the Genoveva quarry in the Napo Province of Ecuador is revealing information about life in a dense, tropical rainforest 112 million years ago, requiring the most convoluted of mental gymnastics for creationists to ignore or deny. This newly described deposit, part of the Hollín Formation in the Oriente Basin, represents the first Mesozoic amber deposit with preserved insects ever discovered in South America — and one of the largest known anywhere on the former Gondwanan supercontinent.
Unlike rock fossils, where finer detail is often lost through mineralisation and geological processes, amber frequently preserves plant and animal life with exquisite microscopic precision. This makes the Ecuadorian deposit, produced at a time when Gondwana was on the verge of splitting into Africa and South America, a rare and invaluable window into the humid, densely vegetated ecosystem of an equatorial rainforest during the Cretaceous Period.
Amber is the solidified resinous sap of trees — often conifers such as araucariaceans — and can originate from branches, trunks or even roots, preserving both aerial and subterranean organisms. Almost all known amber deposits come from the northern hemisphere, particularly from Eurasia and North America, so this southern hemisphere deposit provides an unprecedented opportunity to study an ancient Gondwanan ecosystem at a crucial time in Earth’s evolutionary history.
The contrast between this rich, 112-million-year-old ecosystem and the simplistic biblical creation myth is as stark as it could be. Even if we had no other fossils, the life forms trapped in this amber — representing at least five insect orders, spider silk, and an abundance of pollen and spores from ferns, cycads, conifers and early angiosperms — would comprehensively refute the notion of a young Earth created in its present form.
Another strength of amber as a fossil medium is that it is always contemporaneous with the bioinclusions it preserves — organisms became trapped while the resin was still liquid — removing the additional uncertainties sometimes introduced when dating fossils embedded in sedimentary matrices.
Thousands of years before creationism’s god supposedly decided to create a small, flat planet with a dome over it, centred on a tiny patch of the Middle East, humans were already leaving road signs and directions to water sources carved into rocks in what is now the Arabian desert. These carvings offer a fascinating insight into the region’s prehistoric megafauna—and, of course, all such evidence of early human activity would have been completely obliterated by the biblical genocidal flood, had such an event really occurred as described.
The rock carvings were discovered by an international team of archaeologists, led by the Heritage Commission of the Saudi Ministry of Culture, and including scholars from the Max Planck Institute of Geoanthropology, King Abdullah University of Science and Technology (KAUST), University College London, Griffith University’s Australian Research Centre for Human Evolution (ARCHE), and others. Their findings were published open access in Nature Communications a few days ago.
At the time, the region that is now arid desert was made habitable by a humid period following the Last Glacial Maximum (LGM), when surface water was abundant. Stone tool manufacture from the site shows clear cultural links with Neolithic societies in the Levant—ironically, the very region where the authors of Genesis set most of their imaginative origin myths, apparently oblivious to the deeper history of the area or the existence of earlier human populations beyond their narrow horizons.
A recent archaeological finding, by Beniamino Mecozzi of Sapienza University of Rome, Italy and colleagues, at the site of Casal Lumbroso in northwest Rome, has once again refuted the Bible narrative by extending the known depth of human prehistory far beyond the limits imposed by biblical literalism.
In sediments dated to some 400,000 years before creationism’s mythical 'Creation Week', the research team has uncovered evidence that early humans were butchering elephants with small stone tools and then fashioning large implements from the animals’ bones. These traces of planning, adaptation, and technological innovation demonstrate that human ingenuity was already well advanced hundreds of millennia before the supposed creation of Adam.
More interestingly from a scientific perspective is not the incidental refutation of ancient creation myths, which happens with almost every archaeological and palaeontological discovery, but the fact that these hominins predate the successful Homo sapiens migration out of African and into Eurasia by tens of thousands of years and pre-date even the earliest evidence of Neanderthals in western Eurasia.
Such discoveries highlight the sheer scale of time over which our lineage evolved—an evolutionary saga measured not in millennia but in hundreds of thousands of years. The people who left these marks were not modern humans, but archaic members of the genus Homo, close relatives or ancestors of the Neanderthals. Their world was already ancient when the earliest chapters of Genesis were imagined.
Artist's reconstruction of the ancient Macromyzon siluricus leech.
EK Chan.
Unlike creationist frauds, leeches haven’t always been blood-sucking parasites. Around 473 million years ago, they were probably marine predators preying on small creatures.
It had previously been assumed that leeches evolved around 150–200 million years ago, but this fossil, found in the Waukesha biota — a geological formation in Wisconsin —might more than double that timeline to 473 million years, if confirmed. This extended timescale makes sense, as the complex adaptations required for a blood-sucking lifestyle would have had longer to evolve. However, the classification is disputed and may be an example of convergent evolution. This fossil shows the large posterior sucker that modern leeches still possess, but lacks the anterior suctorial mouthparts used by leeches today to pierce their victims’ skin and suck blood.
The fossil was discovered by researchers from Ohio State University, but was initially unrecognised for what it was until it was identified by Karma Nanglu, a palaeontologist with the University of California, Riverside, during the early pandemic years. Nanglu collaborated with researchers from the University of Toronto, the University of São Paulo, and Ohio State University on a paper describing the fossil, which is now published in PeerJ.
A newly discovered fossil fish from the Late Cretaceous has filled a key gap in the evolutionary record of two major freshwater groups – catfish and carp. The fossil was found by researchers from Western University, Ontario, Canada, the Royal Tyrrell Museum of Palaeontology, and international collaborators. Its discovery is bound to send creationists into another bout of denial as they struggle to cope with the cognitive dissonance between reality and their preferred mythology.
When every fossil is transitional, each new find becomes harder for creationists to ignore—unless they retreat to one of their childish parodies of evolution and pretend it means one species instantly transforming into another, as though a ‘species’ consists of a single individual rather than a population, and evolution is a sudden event rather than a gradual process over time. This caricature allows them to dismiss every transitional fossil as a ‘complete species’ with ‘no evidence of intermediates’. From there, they retreat to Bible literalism, invoking vague categories of ‘kinds’ and imagining evolution as one taxon spontaneously giving rise to another—cats turning into dogs, or amoebas becoming humans—something that, if it ever occurred, would indeed defy any scientific explanation.
Hence their constant demands that science provide evidence for their straw-man version of evolution, while they ignore the overwhelming evidence that actually supports evolutionary theory—arguments deliberately crafted to mislead those ignorant of basic biology and to give them spurious reasons to feel smugly superior to ‘elitist scientists’ with their ‘big words’, as though ignorance were a shortcut to expertise.
So they cling to their childish mythology despite the growing number of fossils showing clear mosaic features linking different taxa—exactly what we would expect from ancestral stem species from which two groups diverged. This newly discovered fossil fish from the Late Cretaceous, displaying a mosaic of catfish and carp characteristics, exemplifies that pattern and sheds light on the evolutionary origins of these two major groups of freshwater fish.

A newly described Jurassic fossil from the Isle of Skye, Scotland, has revealed a remarkable “missing link” between lizards and snakes. The find, named Breugnathair elgolensis, provides important evidence of snake evolution and further undermines creationist claims that no transitional forms exist. The research has just been published in Nature and reported by the American Museum of Natural History.
For creationists, this week must feel much like any other, as science continues to produce paper after paper that refutes their beliefs, while not a single one provides a shred of evidence in support of creationism — whether young-Earth or old-Earth, whether invoking an interventionist deity who micro-manages every detail of the universe, or a distant creator who merely lit the blue touch-paper and now sits back to watch the results.
Science, of course, concerns itself only with material reality. It has no use for evidence-free superstitions or fairy tales of the supernatural — notions born of human imagination and the desire for narrative to fill the gaps in our knowledge and understanding. Creationists, therefore, must rely on self-delusion and the irrational belief in a false dichotomy of “facts versus faith”, where even the slightest perceived flaw in science supposedly means total failure and victory for faith by default.
Sadly for creationists, that long-dreamed-of day when science collapses and their god descends triumphantly from the skies in a chariot — looking for all the world like a Bronze Age tribal despot — seems increasingly remote. Science continues to validate the scientific method and to build knowledge upon verifiable evidence, always willing to revise and refine its understanding in light of new discoveries. One such discovery is that of a transitional Jurassic reptile showing a mosaic of lizard and snake features — exactly what we would expect if snakes and lizards share a common ancestor. The problem with pinning one’s hopes on a false dichotomy that depends on science failing is that every new discovery only strengthens science and renders the alternative ever more irrelevant and untenable.
The troublesome fossil for creationists was discovered about ten years ago on the Isle of Skye, in the Inner Hebrides off Scotland’s west coast, by Roger Benson, Macaulay Curator of the American Museum of Natural History, and his colleagues. Named Breugnathair elgolensis — a Latinised form of the Scots Gaelic for “false snake of Elgol” — it has now been described in an open-access paper in Nature.
This article looks at just one of these developments (more will follow). From the perspective of evolutionary biology, it is not especially remarkable—simply the description of a new species of extinct ichthyosaur, Eurhinosaurus mistelgauensis, from the Lower Jurassic (around 200 million years ago).
But for creationism, it serves as yet another stark reminder of how wrong the biblical creation story and timeline are. To put it bluntly, this fossil would not exist if the Bible’s story were true. It doesn’t take a genius to see how the fact of its existence bears on debates about the truth or falsity of Genesis—though creationists appear to struggle with this basic deductive logic.
In another of those regular events in science, a team of researchers led by the University of Vale do Taquari – Univates, Rio Grande, Brazil, through the Graduate Program in Environment and Development (PPGAD), re-examined material held in the Univates Palaeontological Collection. Using modern equipment that was not available when the fossils were first studied more than 50 years ago, they uncovered new information – and, without intending to, once again demonstrated the weakness of creationist claims. As usual, creationism is refuted by the evidence.
What the team discovered were plant spores preserved in situ in fossils dating to between 298.9 and 252.17 million years ago – long before dinosaurs appeared and well before flowering plants evolved. At that time, the most advanced land plants were spore-bearing, like today’s mosses and ferns. This showed that the original classification as Lycopodites was incorrect. Instead, the fossils belonged to a new genus, which the team named Franscinella, giving the newly described Upper Palaeozoic plant the species name Franscinella riograndensis.
The significance extends further: the spores, now positively linked to this species, are index microfossils found in Permian strata of the Paraná Basin. Yet creationists routinely dismiss the use of index fossils in geochronology as “circular reasoning.” The ability to tie these spores directly to a particular species undermines that objection and strengthens their role in stratigraphy.
An open access paper published in Biology Letters by an international team of palaeontologists, led by Marianne Dehasque of the Department of Organismal Biology, Uppsala University, Sweden, will no doubt bring joy to creationists who prefer to see the world in simple black-and-white terms. It shows that one of the usual definitions of species—a group that can reproduce only with one another—needs revising. The paper reports that the two North American species of mammoth—the northern woolly mammoth (Mammuthus primigenius) and the southern Columbian mammoth (M. columbi)—regularly interbred where their ranges overlapped, and that the offspring were fertile.
In the black-and-white, science-vs-creationism world of creationist thinking, this will be taken to mean that if science is wrong, then creationism must be right, by default.
Creationist joy will be short-lived, however, once they realise that this interbreeding took place long before they believe Earth was created, and that the researchers explain the findings in terms of how mammoths evolved and diversified. Indeed, the evidence supports the theory that the Columbian mammoth itself evolved from a hybrid population—one of the mechanisms of evolution that creationist dogma insists does not occur. Not only is there not the slightest hint that biologists are abandoning the Theory of Evolution (ToE) in favour of creationism—as creationist leaders have claimed for at least half a century—but the ToE is used to explain the observable facts, and it does so with consummate ease.
A newly-identified dinosaur from the Late Triassic of Wales has turned out to be hiding in plain sight. The fossil, discovered in 1899 and displayed for years in the National Museum of Wales, has only now been correctly recognised thanks to modern imaging technology unavailable to earlier researchers.
Originally described by Edwin Tully Newton in 1899 as Zanclodon cambrensis, the specimen has now been reclassified by a team of palaeontologists led by Owain Evans of Bristol University. Since the name Zanclodon is no longer used for early reptiles, the team have given it a new name: Newtonsaurus.
As always, discoveries like this present a problem for creationists. Fossils of species that lived tens or even hundreds of millions of years ago sit uneasily with their narrative that all life was magically created just a few thousand years ago. To preserve that story, they are forced into feats of mental gymnastics — whether by bearing false witness against scientists, rejecting well-established dating techniques, or simply dismissing the evidence outright as “wrong.”
The rocks, however, are not so easily ignored. Unlike ancient manuscripts, said to have been dictated by a god to prophets and accepted only on faith, the fossil record is physical, testable, and open to constant re-examination. Evidence can be checked, rechecked, and reassessed as methods improve — something faith alone cannot provide.
