Malaria: Newly Identified “Crown” Stage Controls Parasite Reproduction

Researchers from the Hebrew University of Jerusalem have uncovered yet another layer of exquisite molecular sophistication in one of humanity’s most persistent and lethal parasites, Plasmodium falciparum, the chief cause of malignant malaria. Their findings, reported in a recent press release and published in the peer-reviewed Journal of Cell Biology, describe a newly identified regulatory “crown” checkpoint that controls parasite reproduction with remarkable precision.

It is difficult to imagine a discovery more awkward for Intelligent Design creationists, because Plasmodium falciparum is precisely the sort of organism that embodies everything Michael Behe and William Dembski insist cannot arise by evolution. Here is complex specified genetic information, tightly regulated developmental choreography, and interlocking biochemical machinery operating across multiple life stages — the very definition, we are told, of “irreducible complexity”.

Unfortunately for the Discovery Institute, this irreducible complexity does not produce a bird’s wing, a human eye, or some uplifting example of divine craftsmanship. It produces malaria — a parasite responsible for immense suffering and hundreds of thousands of deaths every year, mostly children. If complexity is meant to be a hallmark of intelligent design, then the designer’s portfolio includes some rather grim specialities.

The problem is compounded by the fact that Michael Behe has already made malaria central to his arguments. In The Edge of Evolution, he famously pointed to the parasite’s resistance to anti-malarial drugs as an example of the supposed limits of Darwinian evolution, claiming that multiple coordinated mutations were beyond the reach of natural selection. Yet malaria has since become one of the clearest demonstrations that evolution not only occurs, but does so rapidly and repeatedly, exploiting enormous population sizes and intense selection pressures to produce exactly the adaptations Behe claimed were improbable.

As Kenneth Miller pointed out, Behe's mathematical sleight of hand was to assume resistance had to evolve as a single event in a single cell, not across a large population over time - a fallacy of which any good microbiologists should have been aware.

This newly described “crown” stage is simply the latest reminder that biological complexity is not evidence of supernatural design. Evolution predicts complexity wherever it confers survival advantage — including in parasites, pathogens, and diseases. The only real surprise is that creationists continue to present complexity as a theological virtue, when nature so often deploys it in the service of exploitation rather than benevolence.

As ever, none of this will deter creationists from repeating their familiar articles of faith. Faced with an organism whose life cycle resembles a biochemical symphony — regulated checkpoints, specialised invasion machinery, host-cell remodelling, immune evasion, and reproductive stages split between mosquito and human — they will insist that this is not evidence for evolution but evidence against it. The argument, such as it is, runs that complexity must have been present from the start, because it could not have arisen gradually.

But this is simply the old “irreducible complexity” claim in a new disguise: the assertion that because creationists personally cannot imagine intermediate stages, no such stages could have existed. Science, of course, is not obliged to conform to the limits of anyone’s imagination. Evolution does not require that complex systems appear in a single leap. It proceeds by modification of what already exists — co-option, duplication, repurposing, and incremental refinement over deep time — producing the layered complexity we observe today.

Another common retreat is the insistence that this is merely “microevolution”, the trivial shuffling of genes within some mythical created “kind”. Yet Plasmodium falciparum is not merely adjusting the colour of its spots. It is evolving novel biochemical strategies, repeatedly acquiring drug resistance, fine-tuning developmental regulation, and exploiting host environments with extraordinary efficiency. If this is “only microevolution”, then the term has been drained of all meaning.

Refuting Creationism - A Gap-Filling Miniature Dinosaur from 120 Million Years Before 'Creation Week'

Tiny new dinosaur Foskeia pelendonum reshapes the dinosaur f | Vrije Universiteit Brussel

Researchers from the Vrije Universiteit Brussel (VUB), working with colleagues in Spain and elsewhere in Europe, have just described a remarkable new species of dinosaur from the Early Cretaceous of northern Spain. Their findings are the subject of a read-only paper in Papers in Palaeontology.

The tiny herbivore, named Foskeia pelendonum, lived around 125 million years ago, yet it is already forcing palaeontologists to rethink part of the ornithopod family tree. The discovery provides another striking example of how the fossil record continues to grow in detail, resolution, and explanatory power.

This will come as an unwelcome development for creationists, who still cling to the claim that evolution is “just speculation” and that the fossil record contains no meaningful evidence of transitional relationships or evolutionary diversification. On the contrary, finds like Foskeia show exactly what evolutionary science predicts: new lineages appearing in the right strata, in the right environments, with a mixture of ancestral and derived traits that help clarify how later forms evolved.

Creationists will, of course, respond in the usual way. Some will insist that this dinosaur is “just another dinosaur”, as though classification and evolutionary relationships are irrelevant. Others will retreat to the vacuous assertion that it represents merely “variation within a kind”, without ever defining what a “kind” is or explaining why such variation produces a nested hierarchy that maps so precisely onto geological time. And as always, the more committed will simply dismiss the evidence altogether, because no amount of fossil discovery can compete with a belief system that must remain true regardless of what the rocks contain.

Yet the significance of Foskeia pelendonum lies precisely in the details. This was not simply a juvenile form of a larger dinosaur, but a genuinely small-bodied species, confirmed by bone histology to have reached adulthood. Even more intriguingly, it possessed unexpectedly specialised skull and dental features, showing that evolutionary change does not always follow the simplistic “bigger and more advanced” caricature imagined by creationists, but often proceeds through ecological experimentation, miniaturisation, and adaptation to local conditions.

Far from undermining evolutionary theory, discoveries like this strengthen it. They refine the dinosaur family tree, help fill long-recognised gaps in the ornithopod record, and demonstrate once again that the history of life is written not in Bronze Age mythology but in the sedimentary archive of deep time — an archive that continues to contradict creationism with every new fossil unearthed.

Unintelligent Design - A Bacterium That Goes Wrong And Self-Destructs

SAR11 bacteria comprise some 40% of marine bacterial cells, making them an essential part of our ocean ecosystems.

One of Earth’s most abundant organisms is surprisingly fragile

Microbiologists at the University of Southern California (USC) have discovered that one of Earth’s most abundant species, the SAR11 bacterium, has a fundamental — and potentially fatal — ‘design’ flaw. They have just published their findings in Nature Microbiology, and it should make grim reading for any creationists with sufficient courage to read it.

When you have trillions of copies, what does it matter to ‘selfish’ genes if a few billion go wrong and end up destroying the organisms they travel through time in? For an evolved organism, it matters not one tittle or jot to its genes, because they can always produce more copies. So long as there is a sufficiently large population to keep replicating, they will continue to exist and reproduce — and they have no other ultimate function. This is all they evolved to do.

But could we say the same for an organism designed by an omniscient, intelligent designer? What would be intelligent about creating an organism that, under particular but entirely predictable conditions, attempts to reproduce but succeeds only in making repeated copies of its DNA, fails to divide, and enters a runaway cycle of replication until it becomes so disorganised that it can no longer survive and effectively self-destructs?

SAR11 dominates the surface waters of the world’s oceans and accounts for around 40% of marine bacterial cells. As such, it is a vital component at the base of the marine food chain, and is so successful partly because of a process known as genetic streamlining — the evolutionary loss of genes to reduce energy demands in nutrient-poor environments. This alone is not the main problem for creationists to explain, although it does raise the obvious question of why a designer would burden an organism with a genetic load it does not need in the first place.

The real problem is that this streamlining, as an evolved process, comes at a cost. In shedding a load of mostly surplus genes, some essential ones are lost too — including genes that regulate the cell cycle. The result is a failure to divide after genome replication, with the cell instead entering an uncontrolled loop of DNA replication without division.

How on Earth can that be regarded as intelligent design? The organism does exactly what it is ‘designed’ to do under conditions of low nutrient stress, but in doing so falls into an inescapable trap. The consequence is that populations continue to decline even when nutrients later become available again — with potentially serious knock-on effects for other species higher up the food chain.

Malevoent Design - Has Creationism's Divine Malevolence Been Up To Its Old Tricks? - Another Bat Virus Modified To Infect Humans.

Bats Identified as Origin of Unexplained Acute Respiratory Illness and Encephalitis in Bangladesh | Columbia University Mailman School of Public Health

paper just published in Emerging Infectious Diseases by a team led by Nischay Mishra, of the Columbia University Mailman School of Public Health, shows that Pteropine orthoreovirus (PRV) — a bat-borne orthoreovirus — has crossed the species barrier into humans in Bangladesh, causing a Nipah-like illness that is difficult to distinguish clinically from Nipah virus infection. The disease presents primarily as an acute respiratory infection, sometimes accompanied by encephalitis.

It has long been known that bats possess a markedly more effective antiviral immune system than humans. This fact alone presents a problem for creationists who insist that humans — and, conveniently, themselves — are the special creation of an omnibenevolent deity. There is no coherent reason why such a deity would equip bats with a superior immune system while leaving humans comparatively vulnerable, unless the intention were for humans to suffer more infectious disease than is strictly necessary.

However, the bat immune system appears to have a significant evolutionary trade-off. Rather than eliminating viruses entirely, it often suppresses their pathological effects while allowing persistent infection. As a result, bats function as biological incubators in which viruses can circulate, diversify, and evolve. Inevitably, some of these variants acquire the ability to cross species barriers and infect humans. This remains the most parsimonious explanation for the emergence of SARS-CoV-2, the virus responsible for COVID-19 — the pandemic of 2020–2022 that killed tens of millions of people and inflicted severe damage on the global economy.

Creationists argue that complex, specified genetic information must be supplied by their putative intelligent designer and then, by a glaring act of circular reasoning, claim that the mere existence of such information constitutes evidence for that designer. This line of argument has no more merit than insisting that tins of baked beans can only be made by magic pixies, and therefore that the existence of tins of baked beans proves the existence of magic pixies. It is a form of reasoning that functions only for those who lack even a basic grasp of logic.

An additional difficulty for creationists is that PRV could only become infectious to humans if it possessed the precise genetic features required for that capability. Within the internal logic of intelligent design apologetics, the zoonotic PRV must therefore count as the product of deliberate design — and hence as evidence for a malevolent intelligent designer. The usual response is to abandon any pretence that intelligent design is science rather than religion in disguise, and to retreat into Christian fundamentalism, invoking “the Fall” and claiming that some other supernatural entity was empowered to interfere with creation and design its own suite of pathogens and parasites. This claim borders on blasphemy even within Christian theology, which traditionally reserves the creation of living things exclusively to their deity.

Unintelligent Design - The Prolific Waste Of Baby Dinosaurs as Food - 150 Million Years Before 'Creation Week'

Baby dinosaurs a common prey for Late Jurassic predators | UCL News - UCL – University College London.

The prolific-waste reproductive strategy of Late Jurassic dinosaurs has been highlighted in a paper published in a New Mexico Museum of Natural History and Science Bulletin by a team of palaeontologists led by Dr Cassius Morrison of University College London’s Department of Earth Sciences.

The team constructed a detailed food web using fossil data laid down around 150 million years ago in the Morrison Formation of the United States. The Morrison Formation is a prominent sequence of Upper Jurassic sedimentary rocks (approximately 156–147 million years old) spanning around 1.5 million square kilometres across the western United States. It is North America’s most prolific source of dinosaur fossils, preserving vast deposits of mudstone, sandstone, and limestone formed in ancient river systems and floodplains.

Their analysis revealed that a major food source for carnivorous dinosaurs consisted of the young of the largest herbivores. These animals followed a reproductive strategy in which large numbers of offspring were produced and then effectively abandoned after hatching. Such juveniles would have been abundant, vulnerable, and easy prey for predators. This strategy is a familiar one in biology and only makes sense as the outcome of evolutionary processes. As an intelligently designed reproductive strategy, however, it is difficult to make sense of at all.

This is yet another example of the prolific waste that characterises living systems and betrays the absence of intelligent foresight in their design. Prolific waste and unnecessary complexity are hallmarks of evolution, whereas minimal waste and minimal complexity are the defining features of genuinely intelligent design — a distinction I explore in detail in my book The Unintelligent Designer: Refuting the Intelligent Design Hoax.

Malevolent Design - How Complex Specified Genetic Information and Irreducible Complexity Cause Pancreatic Cancer

Study reveals protein linked to spread of pancreatic cancer through nerves

A paper just published in Molecular and Cellular Endocrinology shows how precisely the sort of complex specified information and irreducible complexity that Discovery Institute fellows William A. Dembski and Michael J. Behe proclaim as evidence of intelligent design can instead combine to ensure that pancreatic cancer survives, metastasises, and ultimately kills its victims.

This, of course, is true of many diseases, which simply would not exist unless the right combination of genetic information were present and functioning correctly for the disease itself. Yet creationists routinely compartmentalise their beliefs so that harmful “designs” are excluded and blamed on something else, while only those features that appear to benefit humans are credited to a designer.

In the case of parasites, what is harmful to humans is often beneficial to the parasite, but once again the presence of harm causes the logic of creationist arguments to shift. No longer is this evidence of intelligent design, but of something called “sin”, which appears to operate as an autonomous entity capable not only of corrupting creation but of designing living organisms and manipulating their genomes. The formerly omnipotent, omnibenevolent and omniscient designer god now seems strangely impotent, indolent, or indifferent in the face of this alternative “designer”.

This theology also sits uncomfortably alongside another core fundamentalist belief: that God has a plan for everyone, and that everything that happens in a person’s life occurs as part of this divine plan. Presumably, then, that plan must include any diseases they suffer from, including cancer.

It is therefore difficult to see how creationists can escape the conclusion that their god designs and causes cancer as part of this plan, while continuing to cling to the claim that intelligent design is inherently benevolent.

Creationism Refuted - Termite Evolution By Loss Of Genetic Information and Complexity

Scientists solve the mystery of why termite kings and queens are monogamous - The University of Sydney

Researchers from the University of Sydney have just published a paper on termite evolution in Science which will make depressing reading for any creationists brave enough to attempt it. The study comprehensively refutes several articles of creationist faith.

A common creationist assertion is that loss of genetic information is invariably fatal, so mutations cannot be selected for during evolution. They also insist that evolution, as defined by science, is necessarily a process of increasing complexity, which they then claim would violate the laws of thermodynamics by reducing entropy.

The absurdity of this counter-factual claim is easy to see. Variation between individuals is due to genetic differences, and that variation is only possible if mutations generate novelty. Creationists also conveniently ignore the fact that entropy can decrease locally in open systems. Earth is very much an open system, with a continuous influx of energy from the Sun, so nothing in thermodynamics precludes local increases in order or complexity.

Moreover, the claim is demonstrably false. Many endoparasites, such as parasitic worms, have lost substantial amounts of genetic information as they evolved to rely on their hosts for key functions. Several intestinal worms, for example, have no digestive tract at all, because they absorb nutrients directly from their host’s gut. Evolution does not require an increase or a decrease in complexity as such; it requires only a change in the frequency of alleles in a population over time.

The University of Sydney researchers have now identified another striking example of evolution by gene loss — this time in termites. Their results show a massive loss of genes as termites evolved extreme monogamy and sociality. Paradoxically, a reduction in genetic complexity at the individual level was accompanied by an increase in social complexity at the colony level.

Some of the lost genes are those responsible for producing sperm tails, meaning that termite sperm can no longer swim. This is likely a consequence of strict monogamy within the colony, which removes sperm competition altogether. In species where females mate with multiple males, there is strong selection pressure for highly motile sperm, because the fastest are more likely to fertilise the eggs. In termites, that pressure simply does not exist.

To reach these conclusions, the team — led by Professor Nathan Lo — compared the genomes of ‘domestic’ cockroaches (which share a common ancestor with termites), closely related wood roaches that live in small family groups, and multiple termite species exhibiting different levels of social complexity.

Unintelligent Design - One Design Blunder Led To Another And Ended Up Causing Cancer - Or Was It Deliberate?

A broken DNA repair tool accelerates aging | News from Goethe University Frankfurt

Researchers from Goethe University, Frankfurt am Main, Germany, have shown how a faulty DNA repair mechanism triggers inflammation and leads to accelerated ageing, developmental abnormalities, and cancer.

Their findings are published in Science.

As I explained in my book, The Unintelligent Designer: Exposing the Intelligent Design Hoax, one of the hallmarks of an evolved system — and one which creationists have been conditioned to mistake for evidence of intelligent design — is complexity. In reality, the opposite is true: intelligently designed objects and processes are typically *minimally

complex, doing exactly what is required and no more.

One reason complexity arises in evolved systems is the need for additional layers of processes to compensate for the suboptimal designs that evolution inevitably produces. An intelligently designed process — especially one devised by a designer endowed with foresight — would require no such compensatory mechanisms. It would function reliably every time and be robust enough to withstand environmental stressors and other causes of malfunction. Nor would a perfectly designed copying process be prone to copying errors.

What we observe in reality, however, is an excessively complex system that still malfunctions — and when it does, it can do so unpredictably and catastrophically, leading to increased suffering and even death. The equivalent, in engineering terms, would be an aircraft manufacturer producing planes that were mostly safe most of the time, yet costly to build because they relied on intricate back-up systems to compensate for other components prone to failure — and which nevertheless suffered unpredictable mid-flight failures when those back-ups failed, causing aircraft to fall from the sky. Such an incompetent aircraft manufacturer would not remain in business for long.

In contrast to evolved systems which are overly complex and still prone to errors, an intelligently designed organism would be minimally complex, maximally efficient, robust enough to withstand environmental stressors and work perfectly every time. As so often, what ID predicts is not what we actually observe. In normal science, the falsification of a hypothesis is regarded as confirmation that the hypothesis was wrong, but in creationism the reverse holds; if the facts fail to confirm the hypothesis the facts must be wrong. The hypothesis must be clung to with grim determination, come what may.

Refuting Crationism - How Climate Change Shaped the Evolution of Kangaroos And Wallabies

Red-necked wallaby

QUT - Study maps climate-related evolution of modern kangaroos and wallabies

In a clear example of how evolution is driven by environmental change, a study by scientists at Queensland University of Technology (QUT), led by Professor Matthew J. Phillips, has shown how closely the evolution of Australia’s kangaroos and wallabies maps onto the continent’s long-term climate history. Their findings are published in Molecular Phylogenetics and Evolution.

By tracing the climate record over the last 18 million years and comparing it with the fossil record, the team showed that increasing aridity and habitat variability around 7–9 million years ago coincided with the emergence of the macropodines — the group to which most modern kangaroos and wallabies belong. This was followed by the appearance of incipient grasslands around 5–4.5 million years ago, a period that saw a major diversification of kangaroo and wallaby species.

As expected, there is no evidence of sudden creation without ancestors 6,000–10,000 years ago, nor of a wholesale biological reset following a global flood a few thousand years ago. Instead, the record is one of gradual evolution over deep time, driven by environmental change. The long-predicted failure of the Theory of Evolution to explain and make sense of the evidence once again failed to materialise, as it has every time creationists have claimed it was imminent over the past half-century.

Rather than contradicting evolutionary theory, the evidence fits it like a hand in a glove, adding yet another piece to the growing mountain of supporting data. Once again, the underpinning theory of modern biology is shown to be supported by independent lines of evidence from geology, climatology, and palaeontology, all converging on the same conclusion: life has evolved on an ancient planet responding continuously to changing environments.

Refuting Creationism - How The Transitional Ediacaran Biota Slowly Evolved Into The Cambrian Biota

Ediacaran fossils

How Did These Strange, Ancient Organisms Turn into Such Remarkable Fossils? | GSA News Release 26-01

A recent paper published in the journal Geology by three geologists from Yale, led by Dr Lidya G. Tarhan, explains how the soft-bodied Ediacaran biota came to be preserved in such exquisite detail, while the transition to the (mostly) soft-bodied Cambrian biota and the Cambrian diversification are so poorly represented in the fossil record. It turns out that this was due to the particular chemistry of Ediacaran seawater, which enabled dead organisms to be coated and encased in a fine layer of clay that protected and preserved their structure. As ocean chemistry changed, this fortuitous process became progressively less effective.

Creationists love few things more than a gap in scientific knowledge as somewhere to position their favourite god, presumably having been fooled into believing a false dichotomy — either science can currently explain it or God did it — or at least expecting their target audience to be fooled by it. Sadly for creationists, this has created an ever-decreasing number of places in which to force-fit their ever-shrinking little god, as science, with relentless, unstoppable efficiency, fills one gap after another.

One such gap which creationists regularly trot out and misrepresent is the so-called “Cambrian Explosion”, which they have been fooled into believing was a sudden event occurring at an instant in time, before which there were no multicellular organisms and after which a myriad diverse body plans all appeared overnight without ancestry.

This conveniently ignores two important facts: the pre-existing Ediacaran biota, and the fact that the Ediacaran biota transitioned into the Cambrian biota over a period of some 30 million years.

In reality, of course, there is no such gap — it exists only in the minds of those ignorant enough to believe the misrepresentation. However, there is, or rather was, a gap, and one which creationists would probably prefer not to think about. It was the lack of a good explanation for how the soft-bodied Ediacaran biota came to be preserved in the fossil record in such exquisite detail, while the Cambrian “explosion” only looks like a sudden event because so few of the (soft-bodied) transitional forms were preserved.

Certainly, once it began, the Cambrian was a period of exponential diversification during which hard body parts evolved as defensive structures such as shells, spines, and hard exoskeletons; offensive structures such as jaws; and organs of mobility such as limbs and fins. Also evolving were sense organs and nervous systems. It would have been astonishing almost beyond credibility if every step of a rapid diversification of initially soft-bodied organisms had contrived to leave a fossil record of every stage, so all we really have is an infrequent series of snapshots at discrete locations, each capturing a brief moment in a global evolutionary history lasting about 55 million years.

Refuting Creationism - The Unintelligently Designed Ancestral Potato and How Humans Improved It

This wild potato may change the agricultural story in the American Southwest – @theU

Anthropologists at the University of Utah and the Natural History Museum of Utah have traced the anthropogenic spread and cultivation of a relative of the potato, Solanum jamesii (the Four Corners potato). Their findings are published in PLOS ONE. This plant has been a culinary, medicinally and culturally important food crop across the Colorado Plateau for millennia.

Until now, despite its long history, the extent to which indigenous people domesticated S. jamesii has been unknown. Genetic evidence has shown that it had been transported and cultivated far from its natural range and had acquired frost resistance, longer dormancy and sprouting resilience, all of which made it more suitable for cultivation in its anthropogenic range. The Utah team have now shown how it arrived on the Colorado Plateau from its origins in the south-west USA, probably through a trading network.

A problem which I have found impossible to get a creationist to address without them running for the bolt-hole of ‘mysterious ways’ is the fact that, with only a very few exceptions, every domesticated animal and cultivated plant has been considerably improved on the wild stock and is always the result of a human-mediated evolutionary process. The result is often almost unrecognisable as the same species as their wild ancestor.

Yet according to the Bible, all animals and plants were created for the sole benefit of humankind by a supposedly omnipotent, omniscient god. Had that been so, we could expect them to have been created fit for purpose and perfectly suited to the uses to which we put them. The fact that we have had to adapt them and change them so drastically to make them fit for purpose gives the lie to claims of intelligent design by an omniscient designer.

This relative of the potato therefore serves as an illustration of how humans, unwittingly or otherwise, have modified and changed the distribution of cultivated plants by inadvertently mimicking the process of evolution — mutation → selection → reproduction. S. jamesii is native to the Mogollon Rim, a region spanning south-central Arizona and into the Mogollon Mountains of New Mexico. The researchers were able to build a picture of how this plant was transported from there to the Four Corners region of southern Utah, south-west Colorado and north-west New Mexico by extracting the characteristic starch granules embedded in the stone tools used to process the tubers, recovered from 14 archaeological sites within and beyond the tuber’s natural range.

This research adds to the growing body of evidence that indigenous people in the south-western USA actively cultivated crops of their own and did not just acquire them from other peoples. It had previously been believed that they relied primarily on crops domesticated in Mesoamerica, such as maize, beans or squash. It also adds another species to the long list of plants and animals that have had to be modified from their wild type, and for which creationists are at a loss to explain why their supposed omniscient designer god did not do a very good job of it to begin with.

New 2.6-million-year-old Paranthropus fossil reshapes understanding of early hominins | Biological Sciences Division | The University of Chicago

Research published two days ago in Nature by a team led by University of Chicago paleoanthropologist Professor Zeresenay Alemseged will dismay and delight creationists in about equal measure — especially those who manage to rationalise a fossil dating from about 2.6 million years before they believe Earth and everything on it was created — because it shows that scientists were wrong about something.

It is the news that the jawbone of an archaic hominin, Paranthropus, has been found in Ethiopia some 200 miles further north than the previously believed northern limit of these hominins.

Normally, to a binary-thinking creationist, science being wrong about even the most minor and unimportant detail is “proof” that science is wrong about everything. This childish belief probably stems from them having a single source-book which has been deemed to be inerrant, so even the slightest falsehood in it renders that claim untenable. They assume it is the same with science: that what scientists believe comes from supposedly inerrant textbooks written by “prophets” such as Charles Darwin, serving as the source-books from which all scientists get their information. So, if scientists are ever wrong, all the books from the science libraries of the world can be thrown in the waste bin, leaving creationism’s book of “inerrant” origin myths as the winner.

What they find hard to comprehend, apparently, is that scientific knowledge is cumulative, with current thinking always provisional, pending further confirmation or in need of revision in the light of new information, and that facts are neutral in any dispute, so can be objective referees. They fail to realise that because science works this way, scientists from all over the world will eventually converge on a single answer. Religions, by contrast, because they are not based on evidence but on the tenuous thread of interpretation of an ancient book which itself presents no evidence for its claims, continue to diversify into ever smaller sects, each claiming to have the one true answer but having no evidence to referee the dispute.

But of course, in the best scientific tradition, this jawbone simply adds richness to the hominin evolutionary story and raises the possibility that Paranthropus, like Australopithecus and Homo, was present in the Afar region of Ethiopia. And that opens up the intriguing possibility — given the propensity of hominins to diverge and then hybridise — that modern Homo sapiens could have some Paranthropus ancestry.

Creationism Refuted - An Elephant Bone Tool from 470,000 Years Before 'Creation Week'

Ancient humans made elephant bone tools in Europe half a million years ago | Natural History Museum

The problems for creationists deepened today with news that two scientists, Simon Parfitt of the UCL Institute of Archaeology and a Scientific Associate at the Natural History Museum, London, and Silvia M. Bello of the Natural History Museum, have discovered an elephant bone tool dating from roughly half a million years ago — the oldest such tool discovered in Europe, from a time before anatomically modern hominins had left Africa. They published their findings in Science Advances.

Of course, most creationists will be blissfully unaware of this discovery, as with all such archaeology, because there is no point in being a creationist if you are going to read the latest scientific discoveries. How is that going to help you cling to patently absurd beliefs despite all the evidence against you? Best just ignore it and dismiss it all as some sort of Satanic conspiracy aimed at making you show weakness and change your mind.

Nevertheless, the fact is that this elephant bone tool exists and has been dated to about 490,000 years before creationism’s favourite book of Bronze Age superstitions says Earth existed. It was used by archaic hominins, probably to sharpen dulled flint tools by gently knapping the cutting edges. It was discovered at Boxgrove, Kent, England, in the early 1990s but was not recognised as a tool until recently, when finds from the Boxgrove site were studied in detail using new technology such as 3D scans and scanning electron microscopy, which revealed impact notches with embedded flint fragments.

Bone, being softer than flint, would have been the material of choice for work where precision was important, and elephant bone, with its hard outer layer of compact bone making it more durable, would have been the bone of choice. However, elephants and mammoths were rare in what is now southern England 500,000 years ago, so these tools would have been valuable objects.

It is not clear which archaic hominins used these tools in southern England, but at 500,000 years ago it was probably one of the ancestors of Neanderthals and Denisovans, which form the “muddle in the middle” of the human evolutionary story. Here the problem is not a lack of fossils but an abundance of them, showing varying mixtures of primitive and derived features typical of transitional species, coming somewhere between Homo erectus and Neanderthals. Candidates are H. heidelbergensis and H. antecessor.

The stone tools from Boxgrove are part of the widespread Acheulean technology, which originated in East Africa about 1.95 million years ago and spread across Africa and into western Eurasia after about 1.5 million years ago, persisting until between 200,000 and 100,000 years ago.

Creationism Refuted - How The Mammalian Ear Evolved - 250 Million Years Before 'Creation Week'

Fossil study rewrites timeline of evolution of hearing in mammals | University of Chicago News

A recent paper in Proceedings of the National Academy of Sciences of the USA (PNAS) reports the discovery that an ancestor of mammals, a cynodont called Thrinaxodon liorhinus, had ear structures derived from redundant jaw bones that probably gave it an acute sense of hearing some 250 million years ago — around 50 million years earlier than previously believed. As nocturnal animals, a well-developed sense of hearing would have been hugely advantageous.

The research, by palaeontologists from the University of Chicago, used CT scans of the skull and jawbones of Thrinaxodon to simulate the effects of different sound pressures and frequencies on its anatomy.

Transitional fossils such as this are a major source of embarrassment to creationists because their Bronze Age mythology insists that all species were created fully formed, without ancestry, so there should never be any examples of species evolving or of existing structures being exapted over time for new functions.

Sadly for creationists, the fossil evidence paints an entirely different picture. It is a record of everything creationism predicts should not be there and everything evolution predicts will be. To most normal people, that sort of evidence should strongly suggest that creationism is wrong and that the Theory of Evolution is right.

It is rather like someone who does not believe in gravity stating that if you throw a stone into the air it will stay there and never fall back to Earth. A simple demonstration will establish the falsehood of that claim, just as the fossil record establishes the falsehood of creationist claims.

Background^ Cynodonts and the Evolution of the Mammalian Middle Ear. Cynodonts were a group of synapsid reptiles that lived from the Late Permian to the Early Jurassic and include the direct ancestors of mammals. Unlike true reptiles, cynodonts already showed many mammal-like features, including differentiated teeth, a more upright posture, a secondary palate, and increasingly complex jaw and skull anatomy. Fossils such as Thrinaxodon, Cynognathus, and later forms like Morganucodon document a clear, step-by-step transition from reptile-like synapsids to early mammals.

One of the most striking evolutionary changes recorded in this lineage is the origin of the mammalian middle ear. In reptiles, several small bones at the back of the lower jaw — notably the articular and quadrate — form part of the jaw joint. In mammals, these same bones are repurposed as the malleus and incus of the middle ear, joining the stapes to form the familiar three-bone hearing apparatus. This transformation did not occur suddenly; it unfolded gradually over tens of millions of years.

Fossil cynodonts preserve intermediate stages in which these jaw bones became progressively smaller, less involved in chewing, and increasingly specialised for sound transmission. Some transitional species even show a “double jaw joint,” with both the old reptilian joint and the new mammalian joint functioning simultaneously. This provides direct, physical evidence for exaptation — the evolutionary process in which structures originally evolved for one function are co-opted for a new one.

The result of this long transition was the highly sensitive mammalian middle ear, capable of detecting higher-frequency sounds far better than that of reptiles. This would have been particularly advantageous for small, nocturnal early mammals, allowing them to detect predators and prey in low-light conditions. Far from being a problem for evolutionary theory, the cynodont fossil record is one of its clearest and most elegant confirmations — and one of the most awkward facts for creationism to explain away.

Creationist Claim vs Reality: The Mammalian Middle Ear

Claim:
The mammalian middle ear is “irreducibly complex” and could not have evolved because all three bones — the malleus, incus, and stapes — must be present and perfectly arranged for hearing to work.

Reality:
The fossil record preserves multiple transitional stages showing exactly how the mammalian middle ear evolved from reptile-like jaw bones. In early synapsids and cynodonts, the articular and quadrate bones formed part of the jaw joint. Over time, these bones became progressively smaller and less involved in chewing, while increasingly specialised for transmitting sound.

Claim:
There are no transitional fossils showing this transformation.

Reality:
There are many. Fossils such as Thrinaxodon, Cynognathus, Diarthrognathus, and Morganucodon preserve intermediate anatomies, including species with a functioning “double jaw joint” — one reptilian and one mammalian — operating at the same time. This is exactly what gradual evolution predicts.

Claim:
Repurposing jaw bones for hearing would destroy their original function.

Reality:
It did not. For millions of years, both functions co-existed. As the new mammalian jaw joint (between the dentary and squamosal bones) took over the role of chewing, the old jaw joint bones were freed to specialise for sound transmission. This is a textbook example of exaptation, not a paradox.

Claim:
Complex biological structures appear suddenly.

Reality:
They do not. The step-by-step transformation of jaw bones into middle ear bones is one of the best-documented transitions in the entire fossil record. It is exactly the opposite of what creationism predicts — and exactly what evolutionary theory predicts.

Fossil study rewrites timeline of evolution of hearing in mammals

UChicago paleontologists use CT scanning and simulations to show how a 250-million-year-old mammal predecessor could hear like us

---

One of the most important steps in the evolution of modern mammals was the development of highly sensitive hearing.

The middle ear of mammals, with an eardrum and several small bones, allows us to hear a broad range of frequencies and volumes, which was a big help to early, mostly nocturnal mammal ancestors as they tried to survive alongside dinosaurs.

New research by paleontologists from the University of Chicago shows that this modern mode of hearing evolved much earlier than previously thought. Working with detailed CT scans of the skull and jawbones of Thrinaxodon liorhinus, a 250-million-year-old mammal predecessor, they used engineering methods to simulate the effects of different sound pressures and frequencies on its anatomy.

Their models show the creature likely had an eardrum large enough to hear airborne sound effectively, nearly 50 million years before scientists previously thought this evolved in early mammals.

For almost a century, scientists have been trying to figure out how these animals could hear. These ideas have captivated the imagination of paleontologists who work in mammal evolution, but until now we haven’t had very strong biomechanical tests. Now, with our advances in computational biomechanics, we can start to say smart things about what the anatomy means for how this animal could hear.

Testing a 50-year-old hypothesis

Thrinaxodon was a cynodont, a group of animals from the early Triassic period with features beginning to transition from reptiles to mammals. They had specialized teeth, changes to the palate and diaphragm to improve breathing and metabolism, and probably warm-bloodedness and fur.

In early cynodonts, including Thrinaxodon, the ear bones—malleus, incus, stapes—were attached to their jawbones. Later, these bones separated from the jaw to form a distinct middle ear, considered a key development in the evolution of modern mammals.

Simulations showed that sound waves applied to the eardrum of "Thrinaxodon" (top) would have enabled it to hear much more effectively than through bone conduction alone (bottom).

Fifty years ago, Edgar Allin, a paleontologist at the University of Illinois Chicago, first speculated that cynodonts like Thrinaxodon had a membrane suspended across a hooked structure on the jawbone that was a precursor to the modern eardrum. Until then, scientists who studied mammal evolution mostly believed that early cynodonts heard through bone conduction, or via so-called “jaw listening” where they set their mandibles on the ground to pick up vibrations.

While the eardrum idea was fascinating, there was no way to definitively test if such a structure could work to hear airborne sounds.

Turning fossils into an engineering problem

Modern imaging tools like CT scanning have revolutionized the field of paleontology, allowing scientists to unlock a wealth of information that wouldn’t have been possible through studying physical specimens alone.

Wilken and his advisors, Zhe-Xi Luo and Callum Ross, both professors of organismal biology and anatomy, took a well-known Thrinaxodon specimen from the Museum of Paleontology at the University of California, Berkeley, and scanned it in UChicago’s PaleoCT Laboratory. The resulting 3D model gave them a highly detailed reconstruction of its skull and jawbones, with all the dimensions, shapes, angles and curves they needed to determine how a potential eardrum might function.

Next, they used a software tool called Strand7 to perform finite element analysis, an approach that breaks down a system into smaller parts with different physical characteristics. Such tools are usually used for complex engineering problems, like predicting stresses on bridges, aircraft and buildings, or analyzing heat distribution in engines. The team used the software to simulate how the anatomy of Thrinaxodon would respond to different sound pressures and frequencies, using a library of known properties about the thickness, density and flexibility of bones, ligaments, muscles and skin from living animals.

The results were loud and clear: Thrinaxodon, with an eardrum tucked into a crook on its jawbone, could definitely hear that way much more effectively than through bone conduction. The size and shape of its eardrum would have produced the right vibrations to move the ear bones and generate enough pressure to stimulate its auditory nerves and detect sound frequencies. While it still would have relied on some jaw listening, the eardrum was already responsible for most of its hearing.

Once we have the CT model from the fossil, we can take material properties from extant animals and make it as if our Thrinaxodon came alive. That hasn’t been possible before, and this software simulation showed us that vibration through sound is essentially the way this animal could hear.

Wilken said the new technology allowed them to answer an old question by turning it into an engineering problem.

That’s why this is such a cool problem to study. We took a high concept problem—that is, ‘how do ear bones wiggle in a 250-million-year-old fossil?’—and tested a simple hypothesis using these sophisticated tools. And it turns out in Thrinaxodon, the eardrum does just fine all by itself.

Significance
The middle ear of modern mammals is detached from the mandible and has a soft-tissue eardrum, which allows airborne sound to be heard across a wide range of frequencies. A rich fossil record shows that the middle ear bones of mammals evolved from the jaw bones of their synapsid predecessors, but how this transformation was associated with changes in hearing function is unknown. Our finite element analysis (FEA) of the harmonic response of the mandibular ear bones and soft-tissue eardrum of the synapsid Thrinaxodon suggests that this 250-Mya-old mammal precursor was already capable of tympanic hearing similar to extant mammals and provides evidence that this functional transition occurred very early in mammal evolutionary history.

Abstract
The middle ear of mammals is a major functional innovation, distinctive in that it is detached from the mandible and has a tympanic membrane supported by a ring-like ectotympanic. These novelties of the middle ear have enabled modern mammals to develop more sensitive hearing than all other tetrapods, especially at higher frequencies. Fossils from recent decades have clarified the evolution of the detached middle ear from the jaw bones of Paleozoic therapsids and Mesozoic cynodonts, and the evolution of the tympanum. These discoveries make it possible to answer important questions about the functional significance of these features. Here, we evaluate the relative hearing efficacy of a well-known cynodont precursor to mammals, Thrinaxodon liorhinus. Using finite element analysis (FEA), we calculated the harmonic response of the Thrinaxodon ear to bone-conducted and airborne sound and estimated the sound pressure level (SPL) at the stapedial footplate across a broad range of frequencies. We provide evidence that airborne sound received at the tympanum was the most effective mode of sound reception in Thrinaxodon. In contrast, bone conducted sound through the mandibular bones barely met our estimated hearing threshold. Our findings suggest that, like modern mammals, cynodonts were already reliant on a soft tissue tympanum to receive airborne sound, albeit with limited sensitivity to high frequencies. This is a detailed biomechanical evaluation of tympanum function in the cynodont predecessors of mammals and yields insight into the sequence of functional innovations during the evolution of mammal hearing.

For creationists, this discovery is yet another reminder of how badly their Bronze Age mythology fails when confronted with real-world evidence. The evolutionary origin of the mammalian middle ear is no longer a theoretical reconstruction inferred from comparative anatomy; it is a physical, fossil-documented transition preserved in stone. The fact that Thrinaxodon already shows mammal-like hearing structures 250 million years ago simply pushes that transition even further back in time and fills in yet another gap that creationists like to pretend does not exist.

It also underlines a point that creationists have been trying to evade for decades: evolution does not require sudden leaps or the magical appearance of fully formed organs. What it requires is exactly what the fossil record shows — incremental modifications of existing structures, shaped by selection, and repurposed for new functions as circumstances change. Jaw bones that once transmitted bite forces gradually became exquisitely tuned instruments for transmitting sound. That is not a problem for evolutionary theory; it is one of its strongest empirical confirmations.

Worse still for Intelligent Design advocates, the researchers show no hesitation whatsoever in interpreting what they found within the framework of evolutionary biology. There is no hint of mystery, no appeal to unknown designers, and no suggestion that natural processes are inadequate to explain what is observed. Instead, the anatomy of Thrinaxodon fits neatly into a well-established evolutionary sequence that has been mapped out for decades and is now being refined in ever greater detail as new fossils and new technologies come to light.

So once again, we are left with a familiar contrast. Evolutionary biology makes clear, testable predictions about what we should find in the fossil record — and those predictions keep being confirmed. Creationism, by contrast, predicts that none of this should exist at all. When one worldview consistently matches the evidence and the other consistently fails, there is no honest ambiguity about which one is right.
