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.

The oldest shell jewellery workshop in Western Europe | CNRS

The creationism cult took another blow yesterday with the publication of details of the oldest jewellery workshop yet found in Western Europe—dating to at least 32,000 years before the mythical six-day creation of everything from nothing. The site appears to have been used for the organised manufacture of shell ornaments, suggesting a society in which the production and trade of personal adornment already played an important role.

The discovery, made by a team of scientists from the Centre national de la recherche scientifique (CNRS), Université de Bordeaux, the ministère de la Culture, and Université Toulouse-Jean Jaurès, is published in the Proceedings of the National Academy of Sciences (PNAS). It records the excavation of a Palaeolithic site in southwest France, dating from a period when Homo sapiens were spreading into the region and Neanderthals were in decline.

However, the evidence points to a more complex story — one of coexistence and cultural exchange, or even the absorption of Neanderthals into the expanding H. sapiens populations, with traditions and technologies merging. It also raises the possibility that H. sapiens had been established in the area far earlier, perhaps through an earlier migration wave.

Refuting Creationism - Why Consciousness Doesn't Need A God To Explain it

Major theories of consciousness may have been focusing on the wrong part of the brain

Spend a few days in a Creationism vs. Science group on social media and, before long, you’ll be told that science can’t explain consciousness—because, so the argument goes, matter can’t become self-aware, and consciousness can’t arise from nothing.

In other words, you’ll encounter yet another variation on the combined argument from incredulity, the “god of the gaps” fallacy, and the false dichotomy—presented as if they were sound logic against science, and, since only two possibilities are assumed, in favour of the locally popular version of a creator god.

The more fundamentalist creationists will, of course, also try to “prove” that only humans possess real consciousness, since this sets us apart from other animals and grants us the supposedly unique ability to worship their particular god.

But what creationists can never explain is this: if consciousness is not a function of neurophysiology — in other words, the product of chemistry and physics — why can it be abolished with chemicals such as anaesthetics, or by physical injury?

This makes it all the more interesting that a recent paper in Neuroscience & Biobehavioral Reviews by Peter Copple of the Consciousness and Cognition Lab, Department of Psychology, University of Cambridge, UK, reviewing the sufficient conditions for consciousness, makes no suggestion that consciousness is divorced from neurophysiology or that it requires supernatural intervention to explain.

Refuting Creationism - A Newly-Identified Dinosaur From About 220 Million Years Before 'Creation Week'

September: Newtonsaurus identification | News and features | University of Bristol

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.

12,000-year-old smoked mummies reveal world’s earliest evidence of human mummification

They say that when you dig deep enough, the earth always tells a story—one that often clashes with stories written by humans. A recent archaeological discovery in southern China and Southeast Asia is one of those earth’s stories, and it’s a loud one. Scientists have found human remains, deliberately smoke-dried and ritually treated, dating back between 12,000 and 4,000 years ago. These mummified remains, buried in tight, crouched postures, were mummified by being exposed near low-oxygen smoky fires — not cremated, but preserved by ritual smoke-drying techniques.

A point I've made several times in these blog posts, but one which is worth repeating, is that any archaeology which predates the supposed date of the Biblical genocidal flood is irrefutable evidence that no such flood ever happened, because it simply wouldn’t be there—or at best would be buried under a thick, global layer of silt. Similarly, any archaeological evidence that predates the supposed 6-day creation of the universe is irrefutable evidence that no such creation event happened according to the Bible’s timeline.

Lastly, anything which refutes the Bible’s timeline, or contradicts the occurrence of events described in it, is irrefutable evidence that the Bible could not have been written by the omniscient, omnipotent creator god it claims to describe. So, this recent discovery, reported by a team of archaeologists from Australian, Chinese, and Japanese universities, in reported open access in Proceedings of the National Academy of Sciences of the USA (PNAS) is about as conclusive evidence as you could wish for that the Bible was not written by the god described in it. Any claim that it is an inerrant textbook of science and history is undoubtedly false.

‘Teen’ Pachycephalosaur Butts Into Fossil Record | NC State News

Here we have another of those regular discoveries which, according to the press, supposedly means history will need to be “re-written” — something creationists, always looking for a stick to beat science with, will assume means the whole of history, because science has got everything wrong yet again. Unlike their religion, of course, which — so they claim — has never got anything wrong and is therefore eternally true, including the parts about a six-day creation 6,000–10,000 years ago, a global flood which left no evidence, and a universe consisting of a small, flat planet with a dome over it.

In reality, this is merely journalistic hyperbole designed to draw the reader in — or, in the case of creationists, to be seized upon as ‘scientific’ evidence that science is fatally flawed.

The “re-written” part of history is simply the bit about which we previously had no information. The process is not one of tearing up the past but of filling a gap in our knowledge and thereby arriving at an account closer to reality. In this case, “re-writing the history books” will mean telling a more complete history of a group of dinosaurs. The discovery in question is a 108-million-year-old adolescent pachycephalosaur fossil found in the Gobi Desert, Central Asia. Being both the oldest (by about 15 million years) and the most complete skeleton of this group of dinosaurs yet discovered, it provides crucial information about their origins.

Creationism Refuted - Evolutionary Divergence and A Hybrid Jay

A grue jay? Rare hybrid bird identified in Texas

(b) Hybrid Jay by Brian R. Stokes.

(c) Green Jay by Dan O'Brien (ML390361871). Cornell Lab of Ornithology, Macaulay Library.

An interesting example of hybridisation between two distantly related species of jay has been reported by two biologists at the University of Texas, Austin. The hybrid is a cross between a blue jay (Cyanocitta cristata) and a green jay (Cyanocorax yncas). Although both are jays — members of the crow (Corvid) family — these two belong to different genera that diverged some seven million years ago and, until recently, lived in non-overlapping ranges in North America. Climate change has allowed them to extend their ranges, bringing them into contact only within the past decade.

The reason this is scientifically significant is that it illustrates how divergent evolution proceeds, and why it does not always progress to complete reproductive isolation. Unlike many other vertebrates, the genomic arrangements of birds are remarkably stable. As long as alleles remain in the same chromosomal loci, interbreeding remains possible. This can be disadvantageous if it results in hybrids with reduced fitness. For example, one population may evolve a long, slender bill adapted for one type of seed, while another evolves a short, stout bill for harder seeds. A hybrid might inherit an intermediate bill suited to neither, creating obvious disadvantages. In such cases, natural selection favours the evolution of barriers to hybridisation.

In many organisms, this is achieved by genetic rearrangements that prevent a zygote from developing even when mating occurs—so-called post-zygotic barriers. Where genomes are stable, such rearrangements rarely arise, so species tend instead to evolve pre-zygotic barriers that prevent mating or fertilisation in the first place. Among birds, these often take the form of plumage differences, mating rituals, or song—hence their remarkable diversity.

The Ever-Shrinking Creationists' God - Closing The Genetic Code Origin God-Shaped Gap - No God(s) Found

U of I researchers trace genetic code’s origins to early protein structures | College of Agricultural, Consumer & Environmental Sciences | Illinois

Just published in the Journal of Molecular Biology is a paper by three research scientists at the University of Illinois at Urbana-Champaign that will spread despondency among creationists—at least among those with the courage to read it and the understanding to grasp its significance. Another of their favourite god-shaped gaps has just been slammed shut.

The gap in question is the long-standing mystery of how the genetic code arose through natural processes, without the intervention of a supernatural intelligence. Creationists have long claimed that the genetic code is analogous to a computer program—something they assume must imply a programmer. They bolster this with the usual straw-man arguments and hand-waving about statistical impossibility, declaring that such complexity could not have arisen “by chance alone.”

Of course, that was never more than the familiar argument from ignorant incredulity coupled with the false dichotomy fallacy: because we don’t yet know something, it must have been their particular god. Not any of the other gods, of course—because those aren’t real.

What we do know is that the earliest forms of life appeared on Earth about 3.8 billion years ago, while the genetic code itself did not appear until some 800 million (0.8 billion) years later. Time, therefore, was not a limiting factor: there was no plan, no deadline, and no external programmer. That fact alone should give creationists cause for concern because any decent intelligent designer, especially an omniscient one, would not have taken 0.8 billion years to invent the genetic code.

Now, this team of researchers has produced a plausible explanation (and it only needs to be plausible to refute the claim that no explanation is possible). Their study is based on an analysis of 4.3 billion dipeptide sequences across 1,561 proteomes, representing organisms from all three domains of life: Archaea, Bacteria, and Eukarya. (Proteomes are the complete sets of proteins expressed in an organism.)

To rub salt into creationist wounds, the evidence points to the genetic code having emerged through an evolutionary “bootstrapping” process, in which improvements in the code itself led to improvements in the proteins that controlled the very process of coding — an elegant feedback loop with no need for divine intervention.

Refuting Creationism - How Earth Was Really Made - No God-Magic Needed

High-energy Venus Impacts

An SwRI-led team compared the early impact history of Venus and Earth, determining that Venus experienced higher-energy impacts that created a superheated core. Models show these conditions could create Venus’ extended volcanism and younger surface.

Evolution of Terrestrial Planets
A new SwRI-led paper highlights the scientific progress made in understanding the evolution of terrestrial planets, including the effects of late large impacts on pre-existing modes of tectonics. For instance, the Earth experienced transient subduction, when one tectonic plate slides beneath another. Because Venus’ surface is covered by a single plate, a high-velocity impact led to a superheated core and long-lived volcanism. On Mars, a large, low-velocity impact facilitated variations in its hemispheres. Impacts also modify the atmospheres of terrestrial planets in profound ways, including eliminating or supplementing existing gases.

Creationist myths describe Earth as a flat world under a dome at the centre of the Universe, made just a few thousand years ago. The real story is far more extraordinary: a fragile chain of chance events and natural forces that made life possible on this small rocky planet.

Earth orbits an ordinary star on the edge of the Milky Way, one of billions in one of trillions of galaxies. That it exists at all is down to gravity, physics, and luck. Out of this came a beautiful world teeming with life—including one species able to marvel at the Universe and ask how it all began, and in it's fearful, ignorant infancy, make up the myths to explain it that now pass for science in some scientifically backward cultures.

One early collision with a smaller planetoid gave us the Moon, tides, and seasons; this or a later impact may, according to this study, be responsible for tectonic plates, giving us a forever changing, dynamic planet, driving evolutionary divergence. While not required for life to appear, these events shaped the planet into the diverse, life-rich world we know today.

Refuting Creationism - Look How Wrong The Bible's Authors Were!

Fly through Gaia's 3D map of stellar nurseries

So that creationists can rehearse their excuses for dismissing science and retaining their childish delusion that Genesis is an accurate description of the universe, written or inspired by an omniscient creator god, in spite of the evidence to the contrary, here are some recent images and videos from the European Space Agency (ESA).

Unitelligent Design - A Queen Ant Produces Two Different Species of Male Offspring!

Messor ibericus and Messor structor males hatched from eggs laid by the same queen.

Juvé, Y., Lutrat, C., Ha, A. et al (2025).

One queen ant, two species: the discovery that reshapes what ‘family’ means in nature

Creationists use a deliberately fuzzy and flexible definition of “kinds,” shifting its scope whenever it suits their argument. It can be narrowed down to the species level, broadened to a genus or family, or even stretched to encompass an entire order. On occasion, I’ve even seen it expanded to the absurdity of “animal kind,” depending on what the argument requires. This elasticity allows them to maintain the delusion that evolution never happens in the way biologists describe, and to caricature it instead as one species suddenly giving rise to a completely unrelated species in a single step — their parody of so-called “macro-evolution.”

But the case of the Iberian harvester ant (Messor ibericus) presents a real problem for this narrative. Here the definition of “kind” only needs to extend as far as members of a single genus. That still doesn’t rescue creationists, because this ant has evolved a remarkably complex reproductive strategy that undermines any notion of intelligent design and raises awkward questions about what a “kind” even is. Queens of M. ibericus can only reproduce successfully with males of a related species, Messor structor.

Such interspecies dependence is not unknown in either the animal or plant kingdoms, but M. ibericus takes it a step further. When a queen produces male offspring — instead of the usual sterile female workers — those males may be either M. ibericus or M. structor. In other words, she is doing precisely what creationists constantly demand as “evidence for evolution” - one species producing offspring of another species.

Refuting Creationism - Observed Evolution of Plants on A Volcanic Island

Scientists trace origins of now extinct plant population from volcanically active Nishinoshima | EurekAlert!

Scientisst have a remarkable way to verify one of the fundamental principles of evolutionary biology - the 'founder effect' and how it contributes to allopatric speciation - a process that is hotly disputed by creationists who dogmatically refuse to accept any evidence for evolutionary diversification.

The great thing about science is that its theories can be tested and verified. Even better, they are frequently shown to be correct through evidence. This is in stark contrast to faith as a means of determining truth. Faith is not based on evidence, so it cannot be independently verified; in logical terms, it is unfalsifiable.

That doesn’t mean it can’t be falsified, but rather that there are no tests which, if failed, would demonstrate it false. Take, for example, the creationist claim that “God did it.” How could such a claim ever be tested? With no objective evidence beyond subjective feelings, anecdotes, or alleged personal experiences, there is nothing to examine. And if such a claim were challenged, it could always be shielded with further untestable assertions: “God is untestable,” “God is beyond science,” and so on.

By contrast, evolutionary biology offers theories that are not only testable but also repeatedly confirmed. One such theory is the founder effect. This occurs when a new habitat is colonised by only a small sample of a parent population. Two important factors follow:

1. The new sample is unlikely to perfectly represent the genetic diversity of the parent population, so it will begin with a different allele profile.
2. For the new colony to succeed, the founding individuals must already be somewhat pre-adapted to the environment. Those less well-suited are eliminated, while those better adapted survive and reproduce. Over successive generations, this natural selection creates a population increasingly fit for its new environment. The result is a wave of adaptation and divergence from the parent stock — the essence of allopatric speciation.

The natural “laboratory” for studying this process exists in the form of Nishinoshima, a remote Japanese island subject to frequent volcanic eruptions. Each eruption wipes the island clean of vegetation, effectively resetting the ecosystem and creating opportunities for colonisation by founder populations from elsewhere.

By careful genetic analysis of the, now extinct, Nishinoshima population of Portulaca oleracea, the team were able to show that the parent population was on nearby Chichijima, another volcanic island, however, the Nishinoshima population differed markedly from the parent population, and were derived from a very small founder population. In addition, there was evidence of genetic drift, which is much more significant in a small population than in a larger one - exactly as the Theory of Evolution predicts. Genetic drift is the process where, by chance alone, a neutral allele can increase or decrease in the population. The smaller the population the more quickly an allele can progress to fixation in the population or be eliminated. (for more detail on this, see the Introduction to my book, Twenty Reasons To Reject Creationism: Understanding Evolution (ISBN 13: ISBN-13 : 979-8306548166).

Now, researchers from Tokyo Metropolitan University have reported the results of this natural experiment, and they align precisely with what evolutionary theory predicts.

Location of the Cigar Nebula (M82).

Here we have yet another image taken by the Hubble Space Telescope and released by the European Space Agency—not to belittle the Bible’s account of creation in Genesis, though that happens automatically. The biblical description reflects the view of a pre-scientific people who imagined a flat Earth under a solid dome, with stars as tiny lights stuck to it and the Sun and Moon moving across the sky like lamps hung for our benefit. It reads exactly like the report of someone told to look up and describe what they see without any understanding of what lies beyond.

Modern astronomy shows us something utterly different. The universe is not a small stage with a few lights above it, but a vast, dynamic cosmos shaped by natural processes. Stars are born, live, and die in titanic cycles of creation and destruction; galaxies collide and merge; black holes sculpt their surroundings with unimaginable power.

This particular image, ESA’s Picture of the Week, captures the so-called Cigar Galaxy (Messier 82), a starburst galaxy just 12 million light-years away in the constellation Ursa Major (the Great Bear). Here we see the turbulent heart of a galaxy where new stars are forming in great swathes, driving winds of gas and dust thousands of light-years into space.

The contrast could not be greater: a childlike tale of a sky-dome with a few lights versus the grandeur of a living universe billions of years old and on a scale our ancestors could never have imagined. Contrast the Bible's description with that of ESA's description of the image:

Refuting Creationism - Origins of the People of Papua New-Guinea

New AI Study Clarifies the Origins of Papua New Guineans | University of Tartu

A team of researchers led by Dr. Mayukh Mondal of the Centre for Genomics, Evolution & Medicine, Institute of Genomics, University of Tartu, Estonia, have used AI-powered demographic modelling to estimate the genetic ancestry of the people of Papua New Guinea (PNG), whose origins have long been debated.

Papua New Guineans have physical features that differ noticeably from many Asian populations, and some superficial similarities to sub-Saharan Africans have led to speculation that they might descend from a very early migration out of Africa, predating most other non-African Homo sapiens. This new study strongly challenges that hypothesis: it attributes PNG’s genetic distinctiveness instead to a substantial Denisovan admixture followed by a prolonged period of isolation, a severe population bottleneck, and slower population growth.

According to the creationist mythologies, all human beings alive today descend from Adam and Eve—or, in some versions, from Noah and his family after a global flood. If that were literally true, then all living humans would share a very narrow genetic base: mitochondrial DNA (passed via the maternal line) would be limited to a very small number of variants, and all males would share essentially the same Y-chromosome (barring mutation) tracing back to the same male ancestor.

However, the observable facts are that human genetic diversity is much richer than those narratives predict. The mitochondrial DNA lineages in living people trace back to multiple distinct haplogroups with divergence times of tens to hundreds of thousands of years within Africa and beyond into archaic ancestors; similarly, Y-chromosome diversity indicates many lineages. Our human genome tells a far more complex story: long periods of evolution in isolation, multiple migrations, re-mixing, and interbreeding with related hominin species.

The same applies to other species which creationists mythology insists are the descendants of a small number of survivors of the same genocidal flood. Few living species show evidence of such a narrow genetic bottleneck, which would probably have resulted in far too much inbreeding resulting in extinction for most of them.

All non-African humans today are descended from the major “Out-of-Africa” (OOA) migration(s) of Homo sapiens. As populations moved into Eurasia, they interbred first with Neanderthals, then with Denisovans. Underlying all this, there is also the possibility of genetic contributions from even earlier human migrations (e.g. H. erectus) into the ancestors of Neanderthals, Denisovans, or earlier modern humans. Given the evidence that hominin populations often interbred when they came into contact, it would be surprising if there were no admixture between H. erectus (or similar early lineages) and the predecessors of Neanderthals and Denisovans (often thought to include H. heidelbergensis or H. antecessor).

Refuting Creationism - 242-Million-Year-Old 'Transitional' Lizard Fossil

Agriodontosaurus helsbypetrae fossil (BRSUG 29950-14) in its sandstone matrix.

September: World's oldest lizard | News and features | University of Bristol

Here is yet another fossil that will give creationists a lot to think about. It’s a fossil of the earliest known lepidosaur — the group that includes lizards, snakes, and the tuatara of New Zealand. It is ∼242 million years old and was found in a sandstone deposit in Devon, in southwest Britain. It was picked up on a beach in Devon in 2015, and has been examined by a team from the University of Bristol.

At that age it is very close to the stem of the order Lepidosauria. However, it already displays some “advanced” features, and some of the assumed primitive features are already absent.

One of the primitive features often discussed is the lower temporal bar — a bony rod running between the cheek and the jaw hinge—which is present in the tuatara but absent (“open”) in modern lizards and snakes. This opening gives greater flexibility to the skull, allowing more motion for feeding. Also, many modern lizards have palatal teeth (teeth on the roof of the mouth) which help grip prey.

The fossil skull (from Agriodontosaurus helsbypetrae) has no skull hinge and no palatal teeth, but it does have an open lower temporal bar. In other words, this is a transitional species: it has a mosaic of primitive and derived traits—a pattern Darwin predicted, but which creationists generally dismiss. To creationists, fossils are often denied, mischaracterised, or claimed to be “just as they were created a few thousand years ago.” But this specimen is clear evidence of evolutionary change.

Meanwhile, the evidence of fossil ages—dating back hundreds of millions of years—refutes the idea of a young Earth (~ thousands of years), which cannot be reconciled with the geological, biological, and radiometric data.

None of that undermines the real discovery: an early lepidosaur with a mosaic of features lived in what is now Devon, UK, in the Middle Triassic, about 242 million years ago. As always, in rational enquiry, solid evidence must take priority over magical or mythological claims.

Refuting Creationism - How Rodent Thumbnails Allowed Them to Be So Successful.

Thumbnail of the kangaroo rat.

Rafaela V. Missagia et al. (2025)

Most rodents have thumbnails instead of claws. It might help explain how they took over the world. | EurekAlert!

The discovery that ancient rodents evolved a thumbnail in place of a claw helps explain why they are the most successful mammalian order on the planet. That small anatomical change opened up a whole new range of ecological niches, triggering an explosive radiation of new rodent species.

This fact alone should worry creationists who cling to a child-like understanding of science. Their favourite avoidance tactic—when pressed for an example of evolution—is to retreat hastily down their rabbit hole with the familiar cry: “Ah! But that’s not real, ‘macro’-evolution. That’s just variation within a ‘kind’.”

Of course, creationists are consistently reticent about defining what they mean by “macro-evolution,” or explaining how the processes that supposedly produce it differ from those of normal evolution. In scientific terms, evolution is simply a change in allele frequencies in a population over time. There is no separate mechanism for “macro” versus “micro.”

So here’s the awkward question for them: was the evolution of the thumbnail from a claw a case of “macro-evolution” or not?

According to the new research, led by Rafaela Missagi of the University of São Paulo, Brazil, with collaborators from the Field Museum of Natural History (Chicago, USA), Northwestern University (Chicago, USA), and the Natural History Museum (London, UK), this change was pivotal. It allowed rodents to diversify into countless species—just as the elongation of bat fingers into wings enabled bats to radiate into hundreds of species. Crucially, in both cases no “new structures” were created from nothing; existing ones were repurposed.

This sort of question usually sends creationists scurrying for cover, chanting Bible verses as they go.

Unlike creationist dogma, which collapses under this kind of scrutiny, the new findings provide yet another vindication of evolutionary theory. Evolution predicts that when a new function arises, it can open up new ecological opportunities, leading to rapid diversification. Not because there is a plan, but because natural selection now has something new to work on.

This post is a bit of a change from my usual fare, where I’m busy pulling apart the pseudo-science of creationism with its reliance on magic and one ancient book of myths from a small Bronze Age tribe. Today, instead, I want to share something more uplifting: a glimpse of the rich and colourful life thriving in Britain’s coastal waters.

The footage comes from the Isles of Scilly, a protected area lying just off the tip of Cornwall in the far southwest of Britain. Thanks to the Gulf Stream, these islands enjoy a climate that feels almost Mediterranean — a rare treat for the UK!

A team from the University of Exeter’s Centre for Ecology and Conservation set up remote cameras around the islands to see what they could capture. This was a proof-of-concept project designed to test new ways of monitoring coastal ecosystems. The results didn’t disappoint. Their findings have just been published open-access in the Ecological Society of America’s journal Ecological Applications.

Malevolent Design - How Our Gut Microbiome is 'Designed' to Destroy Our Kidneys - Malevolence or Evolution?

Kidney fibrosis linked to molecule made by gut bacteria – News Bureau

Mostly, our gut microbes are beneficial or at least neutral because we have co-evolved and reached an accommodation. One benefit we derive from their presence is that they make life difficult for potentially harmful organisms, if only by monopolising the available resources and occupying the niches in our gut.

There is a downside, of course, as in any evolved system, which is inevitably a compromise and can tip over into pathology under certain circumstances. But overall, because the disadvantages are more than compensated for by the benefits, the system has evolved and been maintained.

However, a newly discovered downside is that a Staphylococcus species may be implicated in one of the serious complications of diabetes mellitus (DM) — kidney fibrosis and ultimately kidney failure. The discovery was made by researchers at the University of Illinois Urbana-Champaign and Mie University in Japan, co-led by Professor Isaac Cann of Illinois and Professor Esteban Gabazza of Mie University. The bacterium is believed to produce corisin — a small peptide — which is found at high levels in patients with diabetic kidney fibrosis. The researchers have just published their findings, open access, in Nature Communications.

For creationists, this sort of discovery is always a problem, one they normally ignore or blame on “Eve’s sin,” revealing ID creationism for what it is — Bible literalism in a lab coat — which must retreat into mystical theology when faced with problems ID cannot address. Yet creationists also claim that their omniscient creator god is personally responsible for the design of organisms such as Staphylococcus. That would mean it knowingly endowed Staphylococcus with the genes to make corisin, along with all the harmful consequences.

Taking William A. Dembski’s “complex specified genetic information,” which supposedly produces a specific outcome, at face value, the staphylococcal genes are equally “proof” of intelligent design. And so we end up with an unresolved paradox for ID creationism: “complex specified” genes that do us harm, standing as evidence of malevolent design.

Cheese Fungi Help Unlock Secrets of Evolution | Tufts Now

Scientists have found a textbook example of evolution in progress—in the very mould used to mature cheese in caves.

“Show me an example of witnessed evolution!” is one of the stock demands from creationists in online debates. But it’s a trick request. No sooner is an example given than they hurriedly shift the goalposts, redefining evolution into a childish caricature. Instead of the real scientific process, they demand to see a cow turn into a whale overnight, or a mouse suddenly grow wings—some grotesque parody of “macro-evolution” that no biologist has ever claimed happens. Ironically, if such nonsense did occur, it would actually falsify the theory of evolution rather than confirm it.

This intellectual dishonesty is the lifeblood of creationist rhetoric. Their arguments only work by preying on scientific illiteracy in their audience, peddling strawmen and false definitions to cover the absence of any evidence for their own claims.

Meanwhile, science continues as it always has, with evolution properly defined as a change in allele frequency in a population’s gene pool over time. And right on cue, another clear demonstration has just been published in Current Biology.

The researchers studied the fungus Penicillium solitum, which is used to ripen cheese, by following its population over eight years in the controlled cave environment of Jasper Hill Farm. By comparing samples collected in 2016 with those taken more recently, they were able to track both visible and genetic changes in the mould over time.

What they found was striking. The rind colour, once a leafy green, had shifted to a chalky white. Genetic analysis showed this was due to repeated mutations in a pigment-producing gene called alb1, which is responsible for melanin production. In the dark, cave-like conditions, melanin offered no advantage, so natural selection favoured lineages that conserved energy by not producing it. The loss of pigment arose independently several times, through different mutations—including both point mutations and the disruption of the gene by mobile DNA elements.

This is evolution at its most direct: heritable changes in the genetic make-up of a population, producing visible differences in response to environmental conditions. It illustrates a well-known principle called relaxed selection—when a trait is no longer useful, natural selection no longer preserves it, and the trait may fade away. In this case, the shift also altered the appearance and sensory qualities of the cheese, underlining how evolutionary change can have immediate, practical consequences.

Ancient DNA reveals deeply complex Mastodon family and repeated migrations driven by climate change - Brighter World

Creationism is rooted in Bronze Age mythology and rests on a single source, the Bible, whose only claim to authority is its own demonstrably false assertion that it is the inerrant word of a creator god.

This is a claim anyone could make, and it collapses when its statements are compared with the observable world.

For example, biblical genealogies, beginning with a mythical first couple created from dust without ancestors, imply that Earth is only a few thousand years old. In reality, geological and astronomical evidence shows that Earth is about 4.5 billion years old, and the fossil record demonstrates that life was flourishing hundreds of millions of years before the Bible implies creation began.

One striking piece of evidence comes from an analysis of mastodon DNA, which shows that between 100,000 and 200,000 years ago mastodons in North America had already diversified into several genetically distinct populations.

Newly dated 85-million-year-old dino eggs could improve understanding of Cretaceous climate

The dating of a clutch of fossil dinosaur eggs will leave creationists scrambling for excuses to dismiss the evidence and cling to the childish notion that Earth is only 6,000–10,000 years old, created ex nihilo by magic, with all extant and extinct species brought into existence without ancestors just a few days later. In other words, this discovery is yet another small addition to the mountain of evidence showing that the biblical creation story was the work of ignorant Bronze Age people trying to make sense of the world around them, not the word of an omniscient creator god who would have known better.

An added problem for creationists is that the research team used a new method of dating the eggs based on measuring when the eggshell itself formed, rather than relying solely on dating the rock in which the eggs were embedded. The difficulty with the latter approach is that, while it gives the age of the surrounding rock, the mineral grains in that rock may predate the eggs and could have been transported there by water or wind.

The new technique is conceptually similar to the uranium–lead (U–Pb) method used to date zircon crystals in volcanic tuff. Tiny amounts of uranium, which readily substitute into the crystal lattice, are incorporated when the zircon forms, but lead is excluded. Over time, uranium isotopes decay into stable isotopes of lead. Thus, any lead present within a zircon crystal must have come from radioactive decay, and by measuring the ratio of uranium to lead isotopes, scientists can calculate the crystal’s age with high precision.

A very similar process occurs in the carbonate of dinosaur eggshells: uranium is incorporated during formation, but lead is excluded. Measuring uranium–lead isotope ratios in the shell carbonate therefore provides a direct and highly accurate age for the eggs themselves, leaving little room for error.

The nebula is mostly thick, smoky clouds of gas, lit up in blue tones by the stars. Clumps of dust hover before and around the stars; they are mostly dark, but lit around their edges where the starlight erodes them.

Cloudy cluster | ESA/Hubble

This week’s NASA/European Space Agency (ESA) Hubble picture of the week is a stunning cloudy starscape from an impressive star cluster. The scene lies within the Large Magellanic Cloud (LMC), a dwarf galaxy about 160,000 light-years away in the southern constellations Dorado and Mensa. With a mass equal to 10–20% of that of the Milky Way, the LMC is the largest of the dozens of small galaxies orbiting our own.

The light captured in this image began its journey 160,000 years ago, when early Homo sapiens were making their first tentative steps beyond Africa, following in the paths of Homo erectus and encountering Neanderthals, who had already lived in Eurasia for some 100,000 years.

That very distance — 160,000 light-years — alone undermines the biblical timeline. The contrast between this breathtaking glimpse of just a tiny fragment of the universe and the childishly naïve picture painted in Genesis is a near-superfluous refutation of the idea that its description came from an all-knowing creator.

Oldest evidence of humans on ‘Hobbit’s’ island neighbour discovered – who they were remains a mystery - Griffith News

Archaeologists led by Budianto Hakim of Indonesia’s National Research and Innovation Agency (BRIN) and Professor Adam Brumm from Griffith University’s Australian Research Centre for Human Evolution have uncovered evidence of tool-making on the Indonesian island of Sulawesi dating back 1.04 million years. The identity of the toolmakers remains unknown, as no hominin fossils have yet been found on the island. Their discovery has just been published open-access in Nature.

The most likely candidates are Homo erectus or a descendant population that adapted to Sulawesi’s distinctive environment. The island lies close to Flores, home of the diminutive ‘Hobbit’ (H. floresiensis), thought to have evolved from H. erectus through island dwarfism, a process that also produced the miniature elephants of Flores. A related discovery was made in 2019 on Luzon in the Philippines, where H. luzonensis—another likely offshoot of H. erectus—was identified. It is therefore entirely plausible that H. erectus, or one of its evolutionary branches, was present and making tools on Sulawesi more than a million years ago.

For creationists, such finds are troublesome because they align seamlessly with evolutionary theory, showing hominins branching, adapting, and diversifying in different environments, just as Darwin and Wallace first described in 1859. They also highlight the profound role of environment in shaping evolutionary outcomes.

For science, the discovery is particularly significant because it implies that an early hominin was capable of undertaking sea crossings across the formidable ‘Wallace Line’—a biogeographic boundary that long isolated the fauna of Australasia from mainland Asia by preventing the natural dispersal of terrestrial animals.

'Potential biosignatures' found in ancient Mars lake | Imperial News | Imperial College London

Scientists analysing data from NASA’s Perseverance rover have reported a tantalising discovery from Jezero Crater on Mars: rocks rich in minerals and chemical patterns that could represent potential biosignatures — the traces left behind by ancient life. The findings, published by an international team led from Imperial College London, point to the remains of an ancient lake where conditions may once have been favourable for microbial life to take hold.

The evidence comes from mudstones, clays, silica, iron-phosphate and iron-sulphide nodules, along with carbon compounds that appear to have undergone redox reactions. On Earth, such processes are often associated with biology, though the researchers are careful to stress that non-biological explanations are still possible. It will take the return of rock samples to Earth, with far more powerful laboratory techniques, before firm conclusions can be reached.

The Age of Feasting: Late Bronze Age networks developed through massive food festivals, with animals brought from far and wide | EurekAlert!

Archaeologists from Cardiff University have published the largest study of its kind into animal remains from Late Bronze Age Britain, and their findings reveal a surprisingly complex picture of feasting, farming, and far-reaching social networks. The research, published in iScience, reports on multi-isotope analysis of more than 3,500 bones from six prehistoric middens in Wiltshire and the Thames Valley. These vast heaps of discarded remains are the archaeological traces of large communal feasts held some 3,000 years ago.

The team found that the animals consumed—cattle, pigs, and sheep—were not all raised locally. Some were brought from considerable distances, suggesting both a sophisticated agricultural economy and a culture in which travel and exchange linked communities across southern Britain. Such large-scale gatherings, the researchers conclude, were central to forging alliances, maintaining social bonds, and reinforcing ritual practices in the closing centuries of the Bronze Age.

In other words, these middens are the material testimony of thriving societies in Britain whose development ran seamlessly from the Neolithic into the Bronze Age, without any trace of a catastrophic global flood. If Genesis were literal history, such sites could not exist. But they do. The Cardiff findings are therefore another piece of hard archaeological evidence that exposes the biblical flood as a myth, not a record of real events.

Far from being isolated farming villages, Late Bronze Age communities in Britain were enmeshed in a dynamic cultural landscape with trade and ritual at its heart. I have previously written about the political control and economic development in Britain being sufficient to command and supply the manpower needed to undertake massive civil engineering projects such as building Stonehenge and Silbury Hill. Silbury Hill alone took an estimates 18 million man-hours to build (i.e. 500 men working for 15 years) - a level of political and economic development which would have been impossible within the Bible's framework.

And here lies the striking problem for biblical literalism. If we take the chronology given in Genesis at face value, Noah’s Flood is supposed to have occurred around 2348 BCE. By that reckoning, all humans and animals on earth, save those aboard the Ark, were annihilated. The Late Bronze Age middens, however, date to between 1200 and 800 BCE—well after the supposed global deluge. The isotope evidence shows continuity of local herds, supplemented by long-distance transport of animals, not a sudden repopulation from a single Middle Eastern source.

Creationism Refuted - Scientists See A Planet Being Born - No God(s) Involved

A growing baby planet photographed for first time in a ring of darkness | University of Arizona News

Astronomers led by University of Arizona’s Laird Close, alongside Leiden Observatory graduate student Richelle van Capelleveen, have directly observed a planet in the making — WISPIT 2b — nested within the rings of a protoplanetary disk around a young Sun-like star in the constellation Aquila, about 430 light-years away. The planet is confirmed to be about five times Jupiter’s mass, actively accreting gas, and clearing a prominent gap in the disk. This observation aligns almost perfectly with the long-standing scientific model of planet formation—and stands in stark contrast to the biblical narrative of instant land-mass creation, involving no orbit, disk, or extended evolutionary process.

This discovery will be depressing news for creationists, especially when contrasted with the biblical account of Earth’s creation — where magic words allegedly call a small, flat land mass into existence consisting of a few square miles of land around the Canaanite Hills, with no hint of orbiting a star or forming within a protoplanetary disk. The stark mismatch extends beyond metaphor — the actual physical process astronomers observe has no room for magic, and more importantly, aligns precisely with predictions from scientific theories of planetary formation.

Refuting Creationism - How The Placenta is the Product of Sub-Optimal Evolutionary Compromise.

Cooperation and Competition: How Fetal and Maternal Cells Evolved to Work Together - UConn Today

Creationists often imagine the human body as the handiwork of a supreme intelligence, carefully engineered for optimal function. Yet the reality revealed by biology is far messier. Our anatomy and physiology are riddled with compromises, inefficiencies, and vulnerabilities that make far more sense as the outcomes of evolutionary processes than as the products of intelligent design. I give multiple examples of the results of these sub-optimal evolutionary compromises in my book, The Body of Evidence: How the Human Body Refutes Intelligent Design. One striking example lies in the complex relationship between mother and foetus during pregnancy, where cooperation and conflict are locked in an evolutionary arms race.

In a paper published in the Proceedings of the National Academy of Sciences (PNAS), Associate Professor Kshitiz of the Department of Biomedical Engineering, University of Connecticut, together with postdoctoral fellows Yasir Suhail and Wenqiang Du, Gunter Wagner of Yale, and Junaid Afzal of the University of California San Francisco (UCSF), have shown how the interface between mother and foetus in the placenta is the product of evolutionary arms races—not the result of intelligent design, as creationists like to imagine.

Firstly, there is the need for the developing foetus to obtain an adequate supply of nutrients, which requires its placental cells to penetrate into the lining of the mother’s uterus.

Secondly, there is the need for the mother to defend herself against invasion by what her body recognises as a ‘foreign’ organism, part of her evolved immune response. Finally, there is the overarching evolutionary imperative of successful reproduction, which entails the birth of healthy offspring.

What the team discovered is that the inevitable evolutionary compromise involves the foetus’s placental cells producing a protein that suppresses the mother’s immune response. This suppression works only because the mother’s cells have evolved to cooperate, allowing the foetal protein to function.

In other words, the mother’s cells have evolved a strategy for permitting the foetus to dampen her immune system—an immune system that itself evolved in the ancestors of placental mammals. This situation can hardly be credited to the act of a supreme intelligence.
