It is generally accepted by palaeoanthropologists that the genus Homo evolved from an Australopithecus species somewhere in East Africa, most likely in the Afar region of Ethiopia, where the famous Australopithecus afarensis specimen “Lucy” was found. However, it is now widely recognised that the hominin evolutionary tree was far from straightforward, resembling more a tangled bush with side-branches that went extinct, rather than a simple, linear progression.

Given the tendency of our ancestors to diversify and occasionally interbreed, it is entirely possible that the genus Homo emerged from a hybrid population, or even that early Homo back-bred with ancestral australopithecines — especially when two or more species lived in close proximity, as new evidence suggests they did in the Afar region.

Fossils of a previously unknown Australopithecus species and of early Homo have been found in the same area, apparently coexisting. The newly discovered australopithecine is known only from teeth, and there is currently insufficient information to formally name the species. Teeth are often distinctive enough to indicate a previously unrecognised species, but palaeoanthropologists usually require additional skeletal remains — such as jaws, skulls, or postcranial bones — to confirm unique anatomical features and avoid naming a species prematurely.

Of course, because evolution operates over entire populations and across thousands of years, the distinction between the immediately ancestral Australopithecus and the descendant Homo is inherently arbitrary. It likely means far more to modern palaeoanthropologists than it ever did to the hominins themselves.

This new evidence, discovered by an international team working on The Ledi-Geraru Research Project, led by scientists at Arizona State University, indicates that both the unidentified Australopithecus and early Homo lived in the area between 2.6 and 2.8 million years ago. The age estimates were reliably established using volcanic ash layers immediately above and below the fossil-bearing strata. The team’s findings were published recently, open access, in Nature.

Refuting Creationism - The Grand Canyon Is a Treasure Trove Of Cambrian Fossils - From 500 Million Years Before 'Creation Week'

Grand Canyon was a ‘Goldilocks zone’ for the evolution of early animals

One of the things about American creationism that many people in the rest of the world find endearing—if not more than a little irritating—is the ignorant parochialism that underpins so much of it. For example, it is part of the creationist narrative that the Grand Canyon is “proof” of the biblical flood because, so they assert, the layers were laid down during the flood and the canyon was then gouged out by the floodwaters running away. This also plays neatly into the biblical flat Earth idea, because they assume the floodwaters went somewhere—presumably over the edge—having been magically piled up for the best part of a year until the magic was removed.

And of course, it all happened in America, where the important things always happen and where anything that happens is important—when Jesus returns, it will be to America; America is the place God is preparing for Jesus’s return, and so on.

So the recent open-access paper in Science Advances by an international team of palaeontologists led by scientists from Cambridge University, UK, reporting that the Grand Canyon is a rich source of fossils from the Cambrian biota, will no doubt come as a shock to American creationists.

Refuting Creationism - Another Plethora of Transitional Fossils - From 250 Million Years Before 'Creation Week'

Another day, and another clutch of transitional fossils from millions of years before “Creation Week” for creationists to lie about, misrepresent, or simply ignore in order to cope with the resulting cognitive dissonance. This time, it’s not just a single research paper, but a series of 14 published in the Journal of Vertebrate Paleontology.

The fossils are the result of 15 years of excavation at three sites in Africa and cover the 47-million-year Permian era, which ended with the “Great Dying” 252 million years ago — the mass extinction at the end of the Permian in which an estimated 70% of species became extinct. Not only is that timeline fatal to those creationists who like to imagine the Earth and life on it are just 6,000 to 10,000 years old, but the fact of a mass extinction raises insurmountable problems for intelligent design advocates. They would need to explain the intelligence behind designing species only to have them wiped out by a climate catastrophe — one which should have been anticipated by an omniscient designer and could have been prevented by an omnipotent god.

And of course, another problem for creationists is the abundance of these transitional fossils, which, according to creationist dogma, should not exist at all.

Refuting Creationism - Science Fills A Whale Of A Gap - No Gods Found

My last blog post concluded with:

Science moves forward by explaining these transitions; creationism survives only by ignoring them. With each gap that closes, their god has less room to hide, and the story of life becomes clearer without invoking the supernatural.

So, the prediction that more gap-closing transitional fossils would soon be found was hardly a bold one.

And sure enough, along comes just such a paper. To rub salt in creationists’ wounds, like the subject of my previous blog post on transitional penguin fossils, this one is also published by Oxford University Press in the Zoological Journal of the Linnean Society of London—the society to which Darwin and Wallace presented their ground-breaking 1858 papers On the Tendency of Species to Form Varieties, or, to put it another way, On the Origin of Species.

This new paper fills an important gap in the evolution of whales. It was written by Erich Fitzgerald of Museums Victoria Research Institute, Ruairidh Duncan of Monash University, Victoria, Australia, and colleagues. The discovery and its significance are explained in an article in The Conversation by Erich Fitzgerald and Ruairidh Duncan.

Creationism in Crisis - Transitional Penguin Fossils From New Zealand - 60 Million Years Before 'Creation Week'

Dagger beaks and strong wings: new fossils rewrite the penguin story and affirm NZ as a cradle of their evolution.

One of the most glaring flaws in creationist reasoning — among the many — is its desperate reliance on gaps in knowledge as hiding places for their putative god. It’s a strategy that ensures their god grows ever smaller and often vanishes entirely as science steadily closes those gaps. This “god of the gaps” approach is ultimately doomed—either to complete collapse or to a never-ending scramble for new gaps, real or imagined, in the forlorn hope that this time, unlike every other, the gap will contain the one thing they crave: a god that cannot be explained away.

One such gap — of which creationists so far seem blissfully unaware, or we would never hear the end of it — is the evolutionary transition between the flying ancestors of penguins and the modern, flightless penguins whose skeletons have adapted from an aerial to a marine existence. This transformation involved all the changes needed to turn wings into powerful flippers for ‘flying’ underwater, a more upright gait, and feathers adapted for life in the water and for the cold of the Antarctic environment where most species now live.

That gap has just been substantially filled by the discovery of a large collection of ancient penguin fossils in the Waipara Greensand Formation in New Zealand, north of Canterbury. This formation spans roughly 62.5 to 58 million years ago—a period of some 4.5 million years, beginning only a few million years after the extinction of the non-avian dinosaurs at the end of the Cretaceous, 66 million years ago. With every such discovery, the supposed “mystery” shrinks a little more—and the god wedged into it fades further into irrelevance. How these fossils fill the gap in our knowledge of penguin evolution is the subject of an article in The Conversation by two palaeontologists from the University of Canterbury, New Zealand: Vanesa De Pietri, Senior Research Fellow in Palaeontology, and Paul Scofield, Adjunct Professor in Palaeontology. Their article is reprinted here under a Creative Commons licence, reformatted for stylistic consistency.

Refuting Creationism - Ancestors Of Mammals Lived 40 Million Years Earlier Than We Thought.

Using a tooth, researchers have identified the oldest known species of docodont, the ancestor of mammals.

Nova FCT student identified a new ancestor of mammals from a two-millimeter tooth

A student palaeontologist, Sofia Patrocínio, from the Faculty of Science and Technology at the University of Lisbon (Nova FCT), has identified a fossil tooth as belonging to a docodontan – a group of mammaliform vertebrates considered close relatives and ancestors of true mammals. This discovery pushes back the known origin of this group by a further 40 million years.

This is the sort of find that often prompts headlines seemingly designed to play into the hands of anti-science groups such as creationists, with claims like *“The science books will need to be rewritten”* or *“Everything you thought you knew about evolution was wrong!”* These sensationalist lines risk creating the false impression that scientists are constantly realising they were “wrong all along”.

In reality – as in this case – what has happened is that a gap in our knowledge has been filled. Our understanding is now slightly more complete than before. Rather than overturning evolutionary theory, this discovery fits perfectly within it, supporting what was already known: there was a gradual transition from small reptiles to early mammals. The main uncertainty was *when* certain steps in that transition occurred.

Creationists who seize on such discoveries to claim scientists are forever changing their minds overlook an inconvenient detail – the timeline. Nearly all of these fossil finds involve organisms that lived hundreds of thousands, even millions of years before creationists believe the Earth and life began. If anything needs rewriting, it’s the creationist books that peddle disinformation to those willing to pay for material that reassures them their preconceived beliefs are correct – even when the evidence says otherwise.

Sofia Patrocínio and her colleagues have recently published their findings in the journal of the Palaeontological Association, Papers in Palaeontology. The discovery is also covered in a news article from Nova FCT, published in Almadense.

What Were Docodontans? Docodontans were small, extinct mammaliforms that lived during the Jurassic period, between about 201 and 145 million years ago. Although not true mammals, they were close relatives and part of the larger group from which mammals evolved.

They are best known from their distinctive teeth, which had complex cusps adapted for an omnivorous diet of insects, plants, and other small food sources. Fossils suggest docodontans were shrew-like in size and appearance, with some adapted to specialised habitats – including burrowing, climbing, and even semi-aquatic lifestyles.

The group is important to palaeontologists because their anatomy preserves key stages in the evolution from reptile-like synapsids to the first true mammals. Discoveries like the one by Sofia Patrocínio help refine our understanding of when and how early mammal traits emerged.

---

The fossil measures less than seven millimeters in total and is partially hidden in a rock. However, meticulous work has identified a new species that combines the name of a goddess with that of a constellation. The new species pushes back the emergence of this group of animals by 40 million years.

---

After several years of researching a molar tooth from an animal that might resemble a mouse and several months until she was able to publish the scientific article, Sofia Patrocínio "closed" this cycle on Friday, June 13, 2025. The result presented in the scientific journal Papers in Palaeontology owes nothing to bad luck, but it does have its share of incidents, as the paleontologist told ALMADENSE.

"There's a funny story from high school: I had to do a project on paleontology and got a failing grade; I was so upset I said it wouldn't happen again," she says in a relaxed conversation, while admitting that she loves what she does. And she does a lot of things, even though many of them aren't even paid. "Paleontology isn't seen as a serious profession." Something she's determined to change.

Sofia Patrocínio is from Cartaxo and graduated in Environmental Education and Nature Tourism. It's been more than half a dozen years since she enrolled in the program, but the price of student housing elsewhere was unaffordable (then, as it is now) , and it was one of the factors that forced her to stay closer to home and enroll at the Polytechnic Institute of Santarém. After that, she interned at Dino Parque da Lourinhã and stayed on to work there.

It was impossible to remove the fossil from the rock due to the risk of damaging it. In the center of the image, the yellowish structure corresponds to the dentary (mandible), and the dark structure is the partially visible molar.

“It was them [my colleagues at Dino Parque] who encouraged me to do a master's degree in Paleontology at Nova; they said I had a knack for it,” he says, referring to the course at the Faculty of Science and Technology of the University of Lisbon (Nova FCT), which has a campus in the parish of Caparica, Almada.

In one of her master's degree courses, Vertebrate Paleontology, Sofia Patrocínio and her colleagues were challenged to prepare and describe fossils, some from the Lourinhã Museum collection and some from an excavation in Greenland. The then-master's student worked with needles and a microscope to remove the sediments still clinging to the fossil, which was less than seven millimeters long —even so, she was unable to free the entire piece, as we will see.

She then described the fossil in detail and attempted to identify its group and its phylogenetic relationships with other animal groups—in other words, she attempted to place the animal in its proper position on the tree of life. "It had similarities with several groups, but didn't seem to belong to any. It was most likely a new species," says the researcher. "I had so much study material that I could have continued [with the same topic] for my master's degree."

How does a tooth allow us to identify a new species?

The first step was to include the species in the order Docodonta, a group of mammaliforms—the evolutionary predecessors of mammals—with very distinctive molars. To put it simply, the molars were long and low, with a characteristic cusp pattern. (Cusps are the conical protrusions on molars, which we also have.) But this particular tooth had characteristics that didn't fit into any of the previously known genera or species within docodonts.

Docodont fossils are very rare, but there are fossils with entire jaws, which allowed comparison with the available material and ruled out a tooth with a small defect. "If it were just a change in the tooth's morphology, there might be doubt, but I counted five to seven differences," explains Sofia Patrocínio. Among these differences was a cusp facing the tongue.

While the tooth's original pattern allowed it to be classified as a new species, the layer in which it was found offers another new discovery. To determine the age of fossils, paleontologists "measure" the age of rocks found in the same layer. In this case, the fossil would have formed about 200 million years ago, during the transition between the Triassic and Jurassic periods (the period in which a wide variety of easily recognizable dinosaurs emerged). Even more interesting is that this species would have appeared 40 million years before the oldest known docodont species.

A new species at the transition between pre-docodont mammals and docodonts adds another piece to the puzzle of mammalian evolution, particularly the order Docodonta, which diversified and occupied various environments at the same time as large dinosaurs roamed the Earth. Furthermore, this fossil places the origin of docodonts in Greenland and Europe—connected before the continents separated into their current positions—rather than Russia and Asia as previously thought.

The layers of soil containing the fossils are like shelves in a bookcase, each corresponding to a period of time. By exploring each shelf as if reading the books stored there, the scientists were able to date the layer and the fossils—among them a new species of dinosaur, Plateosaurus trossingensis, identified by a fellow student in Sofia's master's program — and also describe the environment. The fossils were found in an ancient lake, with little oxygen in the water and which served as a passageway for many animals.

200 million years ago, when the 'Nujalikodon cassiopeiae' fossil is believed to have formed, what are now Greenland and Europe were connected, and also in contact with the continental plates of North America and Asia.

A goddess tooth named after a constellation

Now 25, Sofia Patrocínio boasts the identification of a new species on her resume. "It's strange; it seems like it hasn't sunk in yet." Whoever discovers a new species can give it a name, naturally following the rules used by the scientific community. A species always has two Latin names (first the genus name, which functions almost like our surnames, and then the "proper name" that conveys the distinctive characteristic), as defined by the scientist Carlos Linnaeus in the mid-18th century.

This new docodont was named Nujalikodon cassiopeiae . Nujalik is the goddess of the earth hunt in Inuit mythology—the indigenous population of the Arctic regions of Canada, Alaska, and Greenland—and "nujalikodon" means "Nujalik's tooth." The specific epithet cassiopeiae owes its name to the constellation Cassiopeia, whose five stars appear to form a W, like the cusps of the molar Sofia Patrocínio studied.

The 831 photographs taken by the scan allowed a three-dimensional reconstruction of the fossil measuring just seven millimeters.

Adapted from Patrocínio et al. (2025) Papers in Paleontology

Naming the species requires all the prior work of studying fossils, in this case a complete molar, the piece of bone that housed the tooth, and the broken roots of a second tooth. But a large portion of the fossil was not visible; it was still embedded within the rock, and removing it could irreparably damage the tooth. Furthermore, it was extremely small, the molar measuring only two millimeters. Therefore, a scan of the fossil was necessary—a kind of CT scan for very small objects—which was very difficult to achieve, says the researcher. "But without the scan, it was impossible to move forward, nor to submit the article for publication." Then, using the 831 photographs from the scan—as if the fossil had been cut into very thin slices—a three-dimensional model was created on the computer, allowing us to see the details hidden within the rock.

Sofia Patrocínio's work was supported by her advisors, Vicente Crespo, a paleontologist at Nova FCT, and Elsa Panciroli, a researcher at the National Museum of Scotland, and involved collaboration with other researchers. The work was funded by the Foundation for Science and Technology, as part of the GeoBioTec project.

Having completed this stage, the paleontologist hopes to continue studying the evolution of mammalian ancestors with a doctorate from the Instituto Superior Técnico of the University of Lisbon. This time, she will study the inner ear—but she will continue to observe bones and very small structures. In the meantime, she will participate in paleontological excavations, collaborate with a fossil database in Portugal, and, in the activities she organizes for Ciência Viva, try to spark children's interest in paleontology.

The oldest definitive docodontan from central East Greenland sheds light on the origin of the clade. Pap Palaeontol, 11: e70022. https://doi.org/10.1002/spp2.70022

ABSTRACT
The first mammaliaforms emerged in the Late Triassic, but their exact origins remain unclear due to the scarcity of fossils from this period. One of the earliest diverging mammaliaform groups, the order Docodonta, became unusually ecomorphologically diverse compared with other early mammals, and this may be connected to the possession of complex molar cusp morphology. The specimen described here, found in the Rhætelv Formation of the Kap Stewart Group (Rhaetian–Sinemurian) of central East Greenland, provides novel information on docodontan origins and evolution, as well as key biogeographic insights into early mammal dispersal. Nujalikodon cassiopeiae gen. et sp. nov. is the first mammaliaform found in the Rhætelv Formation, and is likely to be Early Jurassic (Hettangian) in age. Comprising an incomplete dentary with a single preserved molar, it was visualized using micro-computed tomography; the molar bears similarities to the putative early docodontan Delsatia, and docodontan Dobunnodon. Phylogenetic analysis places Nujalikodon cassiopeiae as a basal member of Docodonta or a close sister taxon, making it one of the oldest definitive docodontans and pushing the origin of the group back to at least the Early Jurassic. It provides insights into the development of docodontan dental complexity, a key factor in their ecological diversification during the Middle to Late Jurassic. Its presence in Greenland supports the hypothesis that docodontans originated in the region now comprising Europe and Greenland before dispersing across the rest of Laurasia.

This fossil tooth extends the known existence of docodontans by around 40 million years, placing them much earlier in the evolutionary timeline than previously documented. This is significant because:

• It strengthens the fossil record for the transition from reptile-like synapsids to early mammals, filling a critical gap rather than overturning existing theory.
• It confirms evolutionary predictions — that mammaliforms had already diversified long before the rise of true mammals, in line with phylogenetic models.
• It demonstrates the self-correcting nature of science — evidence leads to refinements in understanding, not wholesale abandonment of established frameworks. When the evidence changes, scientists change their minds, unlike theologians who try to change the evidence.

For creationism, the problem is twofold: the fossil is tens of millions of years older than the 6,000–10,000-year timeline central to young-Earth creationist belief, and docodontans are transitional, exhibiting a mosaic of traits bridging reptiles and mammals, exactly the kind of “missing links” creationists claim do not exist.

Rather than undermining evolution, this discovery is yet another piece of independent evidence that fits perfectly into its framework — and yet another reminder that creationist models fail when confronted with reality.

Refuting Creationism - Adapting to Climate Change - 56 Million Years Before 'Creation Week'

Ancient soils preserved in the rock, known as paleosols, in the Willwood Formation, Bighorn Basin, Wyoming, are rich fossil sites.

Fossil studies of the extinct predator Dissacus praenuntius offer clues as to how ancient animals responded to environmental changes. The ancient omnivore was about the size of a jackal or a coyote.

An Ancient Predator’s Shift in Diet Offers Clues on Surviving Climate Change | Rutgers University

Long before the supposed "Creation Week" — when creationists claim Earth was magicked into existence just a few thousand years ago — our planet was already teeming with life and undergoing dramatic changes. Around 56 million years ago, a mere tick in geological time, Earth experienced a sharp and rapid rise in global temperatures known as the Paleocene–Eocene Thermal Maximum (PETM). This event had a profound effect on ecosystems and the species that lived through it. Many, of course, did not survive, but those that did, adapted to the new, harsher conditions.

One such survivor was an early mammal, Dissacus praenuntius, a member of the now-extinct Mesonychidae order. D. praenuntius was an omnivore that resembled a hyena, but with small hooves on each toe, and like a hyena, it likely lived as an opportunistic scavenger and predator. Now, a team of palaeontologists has revealed how its behaviour changed during the PETM: it began consuming more bone, presumably because its usual prey had become scarce or disappeared altogether. In this respect, D. praenuntius serves as a record of the environmental pressures of the PETM and how some species responded to survive.

It paints a picture of an Earth that is far removed from the idealised, "perfect" planet imagined in creationist mythology — a planet supposedly fine-tuned for life. Instead, the fossil record tells the story of a world that can quickly become hostile, where survival depends not on divine design but on the ability to adapt — or perish.

Creationism Crushed - By Big Biting Dinosaurs

Dinosaur bite illustrations.

Rowe and Rayfield, Current Biology (2025)

Gigantic, meat-eating dinosaurs didn’t all have strong bites | EurekAlert!

Creationists will likely dismiss the recent paper in Current Biology because, as is common in creationist psychology, any scientific evidence contradicting their fundamental beliefs is either ignored, misrepresented, or actively denied—particularly if it suggests their views should be reconsidered.

The study by Andre J. Rowe and Emily J. Rayfield of the University of Bristol (UK) demonstrates that, during the long stretch of Earth’s history predating creationist timelines, giant carnivorous dinosaurs evolved markedly different jaw mechanics to tackle prey—leading to distinct ecological roles. For example, crushers such as Tyrannosaurus rex developed jaws optimised for forceful crushing, akin to crocodilians, whereas slashers - other large theropods such as allosaurids or spinosaurs - developed weaker jaws tailored to ripping and slashing flesh, like modern Komodo dragons [1.1].

This divergence in feeding mechanics underscores a fundamental principle in evolutionary biology: adaptive radiation and allopatric speciation — whereby offspring inheriting intermediate jaw characteristics (neither fully adapted for crushing nor ripping) would likely be at a disadvantage, reducing their reproductive success. Over time, this selective pressure fosters reproductive barriers and drives lineages apart.

Changes in Diet Drove Physical Evolution in Early Humans | Dartmouth

A recent discovery by palaeoanthropologists, led by researchers from Dartmouth College, Hanover, New Hampshire, USA, highlights the stark difference between how a teleological thinker—such as a creationist—imagines evolution works and how it actually proceeds. The study found that the teeth of ancient hominins evolved over a period of some 700,000 years in response to the increasing availability of soft, starchy foods, which began to replace the coarse, fibrous plant matter they had previously consumed.

A teleological thinker—someone who sees purpose and agency in natural processes—would assume that something *caused* the teeth to evolve in order to better process the new food. However, as the theory of evolution predicts, any variation that improves efficiency in food processing or reduces the now-unnecessary cost of growing and maintaining large teeth will be favoured by natural selection. Over evolutionary time, such traits become more common. In the case of archaic hominins, this meant their teeth gradually became smaller.

Teleological thinkers often make the mistake of believing that asking, "Who or what told the teeth they needed to change?" or "How did the teeth know they had to evolve?" is a meaningful challenge to evolutionary theory. To them, it seems reasonable to assume a supernatural intelligence must be involved.

This simplistic view of evolution is actively encouraged by creationist pseudo-scientists such as William A. Dembski and his colleagues at the Discovery Institute, who claim that the genetic information resulting from such optimisation must have been intelligently designed because it is "specified" for a purpose. Of course, at every stage of human evolution, the genetic information that produced a particular tooth shape was necessarily "specified" for that outcome. Dembski never discloses this to his audience, nor does he attempt to correct the teleological bias on which his movement depends.

An interesting aspect of this discovery is that the evolutionary change in this case was driven not so much by environmental change - the starch foods had always been there - as by a change in behaviour - a case of meme-gene co-evolution, using the term 'meme' in the original sense as coined by Richard Dawkins in The Selfish Gene, to mean a unit of cultural inheritance - the analogue of the gene in genetic inheritance.

Refuting Creationism - A Diverse Human Population in China - 290,000 Years Before 'Creation Week'

Members of the research team.

A study reveals the human diversity in China during Middle Pleistocene | CENIEH

A study recently published in the Journal of Human Evolution reports the discovery of a mixture of archaic and modern traits in the dentition of 300,000-year-old hominin fossils unearthed at the Hualongdong site in Anhui Province, China.

These fossils predate the migration of anatomically modern humans (Homo sapiens) out of Africa by around 250,000 years. They indicate that hominin populations in East Asia were already diversifying and possibly interbreeding with archaic humans, such as Homo erectus, to form lineages distinct from both Neanderthals and Denisovans.

The research, led by Professor Wu Xiujie, director of the Hualongdong excavations, is the result of a longstanding collaboration between scientists from the Dental Anthropology Group at CENIEH — María Martinón-Torres, Director of CENIEH and corresponding author of the paper, and José María Bermúdez de Castro, researcher ad honorem at CENIEH — and the Institute of Vertebrate Paleontology and Paleoanthropology (IVPP) in Beijing.

The findings reveal a rich and complex picture of human evolution in East Asia, wholly at odds with the simplistic biblical narrative still clung to by creationists. That account, written by ancient people with no knowledge of the broader world, reflects a worldview in which Earth was small, flat, covered by a dome, and located at the centre of the universe.

How much time did our ancestors spend up trees? Studying these chimpanzees might help us find out

A new study published in Frontiers in Ecology and Evolution delivers yet more evidence for the Theory of Evolution and decisively contradicts Bible-literalist creationism. By closely studying wild chimpanzees in Tanzania’s Issa Valley—an environment that mirrors the mixed woodland–savannah habitats of our early ancestors—researchers found that these apes still spend most of their time in trees and conduct over 85 % of their bipedal movements arboreally. This finding strongly supports the evolutionary view that human bipedalism did not emerge from a sudden exodus from trees but evolved gradually while our ancestors still relied heavily on arboreal habitats.

What is particularly striking is the complete absence of any doubt among the scientists that evolution, driven by natural selection, is the correct framework for interpreting these observations. At no point do they resort to supernatural explanations or even hint that evolution might be insufficient to explain the data. On the contrary, their conclusions seamlessly integrate with the existing evolutionary narrative, demonstrating how behaviours seen in modern chimpanzees provide a living window into the adaptations of our shared ancestors. This directly undermines the creationist claim that mainstream biologists are “abandoning” evolution in favour of unproven religious explanations—a claim that has no basis in reality.

Creationist dogma insists on static, unchanging “kinds” and appeals to unverifiable supernatural causes. Yet, studies like this show that every aspect of our evolutionary past—anatomical, genetic, and behavioural—can be explained through natural processes, without the need for divine intervention. The evidence for a shared ancestry between humans and other primates grows with every new study, while creationism remains stuck with no predictive power and no scientific methodology.

In short, this research reinforces the power and universality of the Theory of Evolution. The scientists involved didn’t set out to “disprove creationism”; they simply applied rigorous observation and analysis, and the results—once again—fell squarely on the side of evolution. Far from being abandoned, the ToE continues to thrive as the backbone of modern biology, while creationism, with its untestable supernatural entities, offers no explanation at all.

More evidence has emerged that Neanderthals were far from the slow-witted, lumbering brutes of popular myth. In fact, they were highly organised, culturally sophisticated, and capable of processing food on what can only be described as an industrial scale.

This latest insight comes from a team of archaeologists led by researchers from MONREPOS (Leibniz Centre for Archaeology, Germany) and Leiden University (The Netherlands), in collaboration with the State Office for Heritage Management and Archaeology Saxony-Anhalt (Germany). Their findings were recently published in Science Advances.

At a site known as Neumark-Nord 2 in central Germany, dating back 125,000 years, the researchers have discovered compelling evidence of a bone-processing ‘factory’. Here, Neanderthals systematically broke up the massive bones of straight-tusked elephants and other large mammals—including deer, horses, and aurochs—to extract fat from the marrow by steeping the fragments in hot water. The straight-tusked elephant, which could weigh up to 13 tonnes, would have yielded enough meat to feed 2,000 adult humans their daily caloric needs.

This site predates the arrival of modern humans in Europe by tens of thousands of years, placing it firmly within the Neanderthal era. At the time, Europe was enjoying an interglacial period with a climate comparable to today's.

Creationism Refuted - Scientists Got It Wrong About Coelacanths - But Not About Evolution

New examination of fish considered a ‘living fossil’ changes our understanding of vertebrate skull evolution

Here is something that will cause creationists to jump for joy – until they read beyond the headline (if they ever do). Scientists have announced that they were wrong about the evolution of the vertebrate skull, including that of mammals.

However, beneath that headline lie some disappointing facts for creationists:

• The error was uncovered by re-examining the 400-million-year-old skull of a coelacanth.
• The mistake concerns details of how the vertebrate skull evolved – not whether it evolved.
• The paper directly contradicts the common creationist claim that scientists are only permitted to publish research that conforms to the scientific consensus. This study openly challenges the prevailing view.
• The discovery enhances our understanding of how the vertebrate skull evolved from that of ancestral lobe-finned fishes – precisely the kind of evidence creationists would rather didn’t exist.

Still, creationists can enjoy the headline and may even use it to 'prove' to their audience that science is unreliable because scientists sometimes make mistakes. Of course, they’ll likely ignore the fact that the fossil in question is 400 million years old, and gloss over the reality that – unlike religious dogma – science is a process of continuous refinement. Science allows for doubt, re-examination, and re-evaluation. When the evidence changes, scientists change their minds. In contrast, religious dogma is fixed and unchanging, usually despite the evidence, not because of it, hence the widening gap between what creationists are required to believe and what science reveals.

Upon re-examining the cranial musculature of the African coelacanth (Latimeria chalumnae), the researchers found that only 13% of the previously identified evolutionary muscle innovations in major vertebrate lineages were accurate. They also identified nine new evolutionary transformations related to innovations in feeding and respiration.

The researchers, Professor Aléssio Datovo from the University of São Paulo (USP) in Brazil and the late David Johnson from the Smithsonian Institution in the United States, who sadly died when the paper was in review, have just published their findings in Science Advances.

The discovery of 78,000-year-old Neanderthal footprints on a Portuguese beach is yet another blow to creationist pseudoscience. Preserved in the ancient sands of Monte Clérigo, the tracks of an adult male, a child, and a toddler walking together paint a vivid picture of Neanderthal life — not as brutish subhumans, but as highly social beings living in complex family groups, navigating diverse coastal environments long before modern humans entered Europe. Such findings are not only consistent with the evolutionary timeline but utterly irreconcilable with young-Earth creationist beliefs.

According to mainstream geological dating techniques, these footprints were made tens of thousands of years before the supposed biblical date of creation (around 6,000 to 10,000 years ago, depending on interpretation). For creationists who insist that all of Earth’s history must be crammed into a few millennia, these kinds of discoveries are profoundly inconvenient. Worse still, the clarity of the evidence — physical impressions in sediment, dated using well-established methods like optically stimulated luminescence — makes them difficult to hand-wave away.

Faced with such a challenge, creationists will likely fall back on a familiar toolkit of denial strategies. Some will try to cast doubt on the dating methods, resorting to pseudoscientific critiques of OSL or claiming unknown “contamination” skewed the results. Others may assert that the footprints were made after Noah’s Flood — an idea that stretches credulity beyond breaking point given the age and geological context. And, of course, some will simply ignore the evidence altogether, pretending it doesn’t exist or insisting that Neanderthals were just humans who lived in “post-Babel dispersion” times, despite the overwhelming fossil, genetic, and archaeological data to the contrary.

The discovery has been reported recently in the journal Scientific Reports by a team of researchers which includes experts from the Gibraltar National Museum and the University of Lisbon, Portugal.

Refuting Creationism - What Life was Like In Illinois - 300 Million Years Before 'Creation Week'

Recreating Mazon Creek’s 300-million-year-old ecosystem

A major difference between science and religion can be summarised as follows: science embraces reasonable uncertainty, while religion often promotes unreasonable certainty.

In practice, this means science always allows room for doubt—however small—and continually re-examines and reassesses evidence to determine whether a change of understanding is justified. Religion, by contrast, typically seeks reasons not to change its views, no matter how tenuous those reasons may be or how far removed from observable reality.

This essential feature of the scientific method is frequently misrepresented by creationists, who portray science as unreliable precisely because it revises its conclusions in light of new evidence. They contrast this with the supposed ‘eternal truths’ of the Bible, arguing that science books need constant revision while scripture remains unchanging.

One of those supposed eternal truths—about which creationists are not permitted to change their minds—is that the Earth is only a few thousand years old, and that all living things were created ex nihilo in their current forms, with no evolutionary ancestry or shared origins. Science, on the other hand, can re-evaluate the evidence from a 300-million-year-old fossil bed in Illinois and conclude that the original interpretation underestimated the complexity of the ancient ecosystem that once existed there.

A prime example of such a scientific reassessment has recently been published—open access—in the journal Paleobiology. The study was conducted by a team of palaeontologists from the University of Missouri’s College of Arts and Science, in collaboration with Gordon Baird of the Department of Geology & Environmental Sciences at the State University of New York (SUNY), Fredonia.

The work is based on a comprehensive reassessment of the rich fossil deposits from the Mazon Creek Lagerstätte in Illinois, which, during the Carboniferous Period (~300 million years ago), was part of a vast area of tropical swamps, deltas, and shallow seas. These habitats were shaped by rising sea levels that inundated earlier coal-forming wetlands.

What Dinosaur Teeth Reveal About Life 150 Million Years Ago | Leibniz Institute

Some 150 million years before the mythical events of ‘Creation Week’—give or take a few thousand years—our distant ancestors were small, nocturnal, rodent-like mammals eking out an existence in a world dominated by colossal reptiles. Among these dominant life forms were the dinosaurs, thriving in a variety of ecosystems and feeding on plants or other animals, depending on their species.

As they ate, they unwittingly left behind a record of their diet etched into the microscopic wear patterns on the enamel of their teeth. Today, with the help of sophisticated analytical techniques, palaeontologists can read these patterns like a diary of prehistoric meals. And with each new discovery, such as the one published by a team led by Dr Daniela E. Winkler of Kiel University, the yawning gap between ancient mythology and modern science widens ever further. Their findings provide yet another decisive refutation of the simplistic narrative crafted by Bronze Age storytellers—later compiled into what some still insist is the inerrant word of an omniscient creator.

This latest blow to creationist pseudoscience comes in the form of an open-access paper, Dental microwear texture analysis reveals behavioural, ecological and habitat signals in Late Jurassic sauropod dinosaur faunas, published in Nature Ecology & Evolution.

The team focused on the teeth of sauropods—long-necked herbivorous dinosaurs such as Camarasaurus, Brachiosaurus, and Diplodocus — from the Late Jurassic Morrison Formation in North America and the Lusitanian Basin in Portugal. Using a method called Dental Microwear Texture Analysis (DMTA), they examined the microscopic wear patterns caused by feeding, revealing a fascinating spectrum of dietary strategies and environmental adaptations among different species.

What they found demolishes the notion of sauropods as a homogenous group of giant leaf-munchers. Instead, the microwear textures show distinct differences in feeding behaviour, likely linked to differences in available vegetation and habitat. For example, Camarasaurus appears to have consumed tougher, more fibrous plant material—perhaps conifers—while others such as Diplodocus may have specialised in softer vegetation like ferns or aquatic plants. These variations not only suggest niche partitioning, where species avoid direct competition by diversifying their diets, but also point to distinct ecological zones across the ancient landscapes they inhabited.

Even more telling is the comparison between North American and European sauropods. Despite being closely related, the differences in their dental microwear suggest adaptations to different environmental pressures and available flora, implying behavioural flexibility and evolutionary divergence shaped by their respective habitats.

Such complexity and diversity, preserved for over 150 million years in the microscopic textures of fossilised teeth, are a world away from the simplistic narratives of static 'kinds' created in a single week. Instead, we see a dynamic, evolving biosphere responding to ecological challenges—exactly what we’d expect in a world governed by natural selection and deep time.

Creationism In Crisis - Neanderthals With Different Cullinary Styles - 50,000 Years Before 'Creation Week'

Specialty of the house: Neanderthals at two nearby caves butchered the same prey in different ways, suggesting local food traditions

More embarrassment for creationists comes in the form of new evidence that Neanderthals were butchering and cooking meat in two caves in what is now Israel. Not only did this occur some 40,000 to 50,000 years before creationists believe the Earth was created, but it also shows that Neanderthal culture had diversified into distinct culinary traditions—even among populations inhabiting neighbouring areas.

The most damning evidence against creationist claims is, of course, the very existence of such archaeological remains. According to the biblical narrative of a global, genocidal flood just a few thousand years ago, this evidence simply should not exist. Such a cataclysm would have erased any trace of it—or at best buried it beneath thick layers of chaotic silt, jumbled together with fossils of plants and animals from distant land masses in no coherent stratigraphic order.

The evidence for Neanderthal cultural diversity comes from researchers at the Hebrew University of Jerusalem, who studied remains in the nearby caves of Amud and Kebara, located just 70 km apart.

What they found was a marked difference in how the two Neanderthal groups butchered their prey, including whether they processed the carcasses at the kill site or transported them back to their caves for preparation. There also appear to be differences in how the meat was cooked.

The researchers’ findings are published in the journal Frontiers in Environmental Archaeology.

Creationism Refuted - A Flint Arrowhead Embeded In A Human Rib Is Hurting Creationism

Arrowhead embedded in a human rib reveals prehistoric violence in the Pyrenees over 4,000 years ago

Around the time creationists claim Earth was undergoing a global flood — a mass genocide by drowning, supposedly enacted by a deity - a belief based solely on the origin myths of a Bronze Age Middle Eastern pastoralist tribe — people in the Pyrenees were engaged in violent conflict, using bows and arrows. Unlike biblical mythology, this insight is grounded in tangible evidence: a human rib bone with a flint arrowhead still embedded in it. Remarkably, the injury had healed before the individual died, suggesting they survived the attack for some time. The rib was found in a mass grave at Roc de les Orenetes (Queralbs, Girona), alongside the remains of several others, many of whom showed signs of trauma from blunt or sharp weapons, particularly to the head and upper body.

The timing of this violence — dated to between 4,100 and 4,500 years ago — is problematic for biblical literalists. If the Genesis flood had truly occurred as described, these remains should either have been destroyed or buried beneath a thick layer of flood-deposited silt, mixed with the remains of animals and plants not native to the region. Alternatively, one must believe that just a few years after a supposed global reset that reduced humanity to eight survivors, their descendants had multiplied sufficiently to form warring groups in the mountains of what is now northern Spain.

And yet, these individuals show no sign of having heard of Noah, his family, or the god who allegedly saved them. There’s no indication of the monotheistic religion supposedly preserved aboard the ark. If the flood story were true, the moral lesson it was intended to deliver seems to have been forgotten almost immediately, everywhere except among a small group in the Canaanite hills.

This discovery joins a growing list of archaeological findings that contradict the flood narrative. Far from showing a global cataclysm, the archaeological record reveals continuous human habitation before, during, and after the time the flood is supposed to have occurred—with no signs of interruption, no replacement by a Near Eastern culture, and no characteristic flood-deposited sediment layer.

It’s almost as if the global flood never happened. Not only is there no geological or archaeological evidence supporting it, but what evidence we do have consistently contradicts it. This find from the Pyrenees is yet another example.

Creationism Refuted - There May Have Been Two Or More Species Of the Hominin Paranthropus That Interbred

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

Where exactly the archaic hominin, Paranthropus robustus fits into the human evolutionary tree remains a subject of debate among palaeontologists. This species lived in southern Africa around 2 million years ago. They walked upright, indicating a shared ancestry with the Australopithecus and the later Homo genus. However, their comparatively small brains and massive jaws and teeth suggest a distinct evolutionary path, likely adapted for processing tough, fibrous plant material.

Determining their precise place in our evolutionary history would ideally require DNA analysis—but DNA does not survive long in the warm African climate. To overcome this limitation, a team of African and European researchers from the fields of molecular science, chemistry, and palaeoanthropology turned to a cutting-edge technique known as palaeoproteomics. By analysing proteins recovered from ancient tooth enamel, they were able to infer aspects of the underlying DNA, since the amino acid sequence in proteins is directly determined by the nucleotide sequence in DNA.

Their findings suggest that the story of early hominins is more complex than previously thought. There may have been more than one closely related species, with evidence of interbreeding or genetic divergence followed by remixing — patterns that would later come to characterise the tangled branches of the hominin family tree.

The research team included three postdoctoral scientists from the University of Copenhagen — Palesa P. Madupe, Claire Koenig, and Ioannis Patramanis — who have written about their work and its significance in the open-access magazine The Conversation.

Their findings are also published in Science.

When someone grows up being threatened with divine punishment for merely entertaining doubts about the literal truth of the Bible, it's hardly surprising that real-world evidence struggles to break through the psychological defences they've built to protect themselves. This phenomenon is what atheist author and philosopher, Professor Peter Boghossian refers to as doxastic closure — a mental state in which contrary ideas are shut out before they can even be considered.

Former young-Earth creationist and now science advocate and geologist Glenn Morton once described it as like having a “gatekeeper demon” perched on the edge of your consciousness—filtering out any facts or logical arguments that challenge creationist beliefs, while admitting only those misrepresentations of science that appear to support them.

In this mindset, inconvenient realities — such as the discovery of a 145-million-year-old fossil of an early mammal — are unlikely to dent the conviction that the Earth is only 6,000 to 10,000 years old, and that all animals were created in a single supernatural event. In this view, evolution is simply an illusion, no matter how well the evidence supports it.

Even so, for any creationist with the courage and intellectual honesty to read this far, the story of that inconvenient little fossil is well worth exploring. It was discovered by a palaeontology student from the University of Portsmouth, along the Dorset coast of England, and is the subject of a recent paper in Proceedings of the Geologists’ Association.

This find marks the first discovery of a multituberculate jaw at Swanage since Victorian times. Its distinct size and shape confirmed it as a completely new species.
