Discoveries from a 125,000-year-old lakeshore reveal life in a greener Arabia

Some 125,000 years ago, people living beside a freshwater lake in southern Arabia were making hunting weapons and exploiting the plants and animals around them. This was roughly 119,000 years before the universe supposedly existed, according to the familiar young-Earth creationist interpretation of Genesis. Far to the south of the region in which the biblical traditions took shape, a chapter of human history was unfolding for which those traditions provide neither a chronology nor an explanation.

The evidence comes from ‘Uruq Aljelibah, beside the ancient lake in the Mundafan basin of southern Saudi Arabia, now part of the forbidding Rub’ al-Khali, or Empty Quarter. Reported in Science, the discovery reveals a landscape very different from today’s desert.

Fresh water and surrounding vegetation supported human activity and abundant wildlife. As a Griffith University news release explains, the surviving evidence includes stone hunting points, traces of the materials used to attach them to shafts, and chemical residues suggesting that some weapons may have carried plant poisons. These were people with practical knowledge of their environment and the skills to combine different materials into effective tools.

The researchers recovered more than 5,500 stone tools and pieces of manufacturing debris. Luminescence dating of the deposits, supported by evidence from hippopotamus teeth, places the archaeological shoreline at about 125,000 years ago. The resulting picture is of people making tools, processing plants and exploiting animal resources during a wetter phase of Arabia’s history. Their world has disappeared, but enough of its physical record remains to reconstruct aspects of their daily lives.

This adds an important dimension to the story of human dispersal out of Africa. Arabia was more than a stretch of territory to cross on the way somewhere else: during favourable climatic intervals, it offered environments in which people could live and apply sophisticated technologies. Human expansion involved repeated movements through changing landscapes, with opportunities opening and closing as water and other resources became available or disappeared. The precise routes and the relationships between early populations and later migrants remain subjects of research. This site helps illuminate how people lived during that wider history without resolving every question about their ancestry or eventual fate.

For biblical literalism, however, the difficulty is more fundamental than an unanswered question about a migration route. People cannot have been making hunting weapons 125,000 years ago if humanity began only a few thousand years ago. Genesis contains no recognisable account of this Arabian prehistory, its vanished lakes or its place in human dispersal. That omission alone would not disprove a religious belief, but the chronology directly contradicts young-Earth creationism. The contrast is precisely what we would expect from ancient origin stories composed by people who lacked knowledge of the deep history of their wider region.

Creationism Refuted - Soft Structure Preserved In Crinoid Fossil - From 452 Million Year Before 'Creation Week'

452 million-year-old fossil crinoid showing close up of tube feet

From: Selina R. Cole, David F. Wright, et. al. (2026)

Crinoid fossil with preserved 'soft' tissues.

OU Paleontologists Make "One in a Million" Discovery of Soft Tissue Preserved in 450-Million-Year-Old Fossil

A report of “soft tissue” preserved in a fossil more than 450 million years old is an obvious invitation to a familiar creationist misrepresentation: soft tissue decays, therefore the fossil cannot be that old, therefore the geological timescale must be wrong. The argument may sound persuasive to anyone who imagines a palaeontologist uncovering fresh flesh inside an ancient rock. Its fatal flaw is that this is not what the researchers have reported.

The discovery, described in Royal Society Open Science by Selina R. Cole and colleagues, concerns the delicate feeding structures of an extinct crinoid, Dendrocrinus simcoensis, from the Late Ordovician of Québec, approximately 452 million years ago. Crinoids are marine relatives of starfish and sea urchins. Their tube feet normally disappear after death, leaving the hard skeletal parts to dominate the fossil record. In these exceptional specimens, however, the anatomy of the tube feet has been recorded by mineralisation: the paper describes their preservation as pyrite films.

That distinction is the whole point. In palaeontology, “soft-tissue preservation” describes the preservation of evidence of structures that were soft during life; it does not, by itself, identify the chemical composition of the fossil or mean that those structures remain soft today. Here, the reported evidence is a mineral record of delicate anatomy, not a demonstration that fresh tissue has resisted decomposition for hundreds of millions of years. An impression of a leaf does not require the original leaf to remain intact. Nor does a mineral replica of a feeding structure require the original flesh to survive alongside it.

The University of Oklahoma’s news release understandably emphasises the rarity of the find, but its language about soft tissues having “survived” can invite precisely this confusion when detached from the paper’s explanation. Anyone wishing to claim that this discovery overturns the dating must first address what was actually found. Calculations about how quickly unmineralised flesh would rot do not establish the age of a fossil in which minerals preserve the form of that flesh. They address a different material and a different process.

Creationism Refuted - Now It's A Giant Rodent From Thailand - 34 Million Years Before 'Creation Week'

Giant, prehistoric rodent fossils discovered in southern Thailand | Newsroom - McGill University

Two fossil teeth from southern Thailand have added another chapter to the evolutionary history of rodents, set approximately 34 million years before Bible literalists imagine the world was created. Described in Scientific Reports, the newly named Yakamys sirindhornae was an exceptionally large member of an early rodent family. Its discovery also illustrates something creationist propaganda routinely misrepresents: scientists use evolutionary theory to interpret new evidence, revise earlier interpretations and identify questions that remain unanswered.

The fossils come from the Krabi Basin and comprise a lower molar and a fragmentary lower incisor, provisionally assigned to the same species because of their exceptional size and occurrence close together in the same fossil-bearing layer. The deposits date to approximately 35.1–33.7 million years ago, based on their mammalian assemblage and magnetic polarity. That places this animal in the late Eocene, tens of millions of years outside the few thousand years allowed by young-Earth creationism. Uncertainty about its weight does nothing to remove that chronological difficulty.

Comparisons of tooth structure and the microscopic organisation of the incisor enamel support its assignment to the extinct Ischyromyidae. Within that evolutionary framework, its large size becomes informative: substantial increases in body size had occurred in an early rodent lineage long before the better-known giant rodents of South America. The discovery broadens our understanding of when and where rodent gigantism evolved. It does not establish that all giant rodents descended from this species, nor does the limited material resolve its precise position within the family.

The much-publicised estimate of about 30 kilograms deserves equally careful treatment. Seven equations relating the dimensions of living rodents' teeth to body mass produced estimates ranging from 21.4 to 47.3 kilograms. The authors use approximately 30 kilograms as a rounded summary, explicitly acknowledging substantial uncertainty. These are estimates derived from comparative measurements, not a weighing of the extinct animal. Further discoveries could refine them, just as earlier estimates for some South American giant rodents have been revised.

This is science doing what it should: testing interpretations against evidence and distinguishing firm observations from provisional inferences. The fossils expand a previously incomplete picture of rodent evolution, while leaving questions about ancestry, ecology and the causes of large body size open to investigation. Evolutionary theory provides the framework in which those questions can be asked and tested; it does not require palaeontologists to pretend that two teeth reveal an animal's entire history.

Rare fossil discovery reveals new dinosaur species that were specialized fruit-eaters | Royal Ontario Museum

A dinosaur nicknamed the “hell chicken” might sound like an especially unpleasant predator, but its remarkable skull suggests rather different eating habits. Infernogallus jamesi, a turkey-sized dinosaur from the approximately 66-million-year-old Hell Creek Formation of North America, appears to have specialised in processing soft plant foods, probably including fleshy fruit. Behind the entertaining name lies a useful illustration of evolution: a lineage descended from carnivorous ancestors acquiring a feeding apparatus suited to a very different diet.

The discovery is described in a paper in Nature Communications by Gregory Funston and colleague. Infernogallus belonged to the caenagnathids, a group of toothless, feathered oviraptorosaurs whose feeding habits have been difficult to establish. Its unusually complete skull has now provided evidence that isolated bones could not supply.

Using CT scans and anatomical reconstruction, the researchers investigated how its jaws would have worked. The arrangement of the palate and jaw muscles indicates that the lower jaw could move backwards and forwards, while opposing ridges and grooves helped process food inside the mouth. Rather than an apparatus for tearing flesh, this was suited to mashing softer material. Particularly revealing is the resemblance to feeding adaptations in living fruit-eating parrots: an example of convergent evolution, in which similar functional demands produce comparable adaptations in separate evolutionary lineages.

There is an important distinction here between reconstructing a feeding mechanism and finding the remains of an animal’s last meal. The evidence supports specialised herbivory and makes fleshy fruit a strong candidate, but it does not establish an exclusively fruit-based diet. Nor does it demonstrate that these dinosaurs dispersed seeds or drove the evolution of fruit. The authors identify a potentially significant relationship between dinosaur feeding specialisations and the diversification of flowering plants, while acknowledging that the ecological details remain uncertain.

For creationism, the difficulty extends beyond the familiar problem of a dinosaur living tens of millions of years before the supposed biblical Creation Week. This animal belongs within an evolutionary history of changing anatomy, changing diets and changing ecosystems. Its feeding apparatus was built from the inherited structures of a theropod skull, modified for a new way of obtaining food. Calling it a separately created “kind” supplies neither an explanation for those anatomical relationships nor a testable account of how its specialisations arose.

Creationism Refuted - Reconstructing Europe's Ancient Landscape - Long Before 'Creation Week'

Dense, dark forests in Europe are a modern phenomenon

Europe’s landscapes have a history far older, richer and more dynamic than anything envisaged by the authors of Genesis. Long before humans cleared fields, planted crops or managed woodlands, changing communities of plants and animals were shaping the continent’s vegetation. The countryside was neither a finished creation nor a permanent backdrop against which life played out. It was itself the changing product of ecological interactions operating over millions of years.

A review published in Biological Conservation, by Szymon Czyżewski and colleagues, examines that history across approximately 23 million years. The researchers challenge the familiar picture of prehistoric Europe as an almost continuous expanse of dark, closed-canopy forest. Their synthesis instead supports a widespread mosaic of grassland, scrub, open woodland and denser forest patches, with large herbivores playing an important role in maintaining this variety.

This reconstruction rests on several complementary sources of evidence, including fossil pollen, plant remains, charcoal, animal teeth and ancient environmental DNA. Together, these records allow researchers to investigate landscapes that no human observer ever saw. The result is not a picture of one habitat remaining unchanged for 23 million years, but of recurring landscape patterns within a long history of ecological change.

The animals were active participants in that history. Feeding and disturbance by large herbivores helped maintain open vegetation; their disappearance could alter the balance between trees and open ground. Later, people introduced further changes through hunting, burning, farming and livestock grazing. What we now regard as “natural” therefore requires historical explanation: today’s landscape is not necessarily a reliable guide to the environments in which its species evolved.

For young-Earth creationism, the difficulty begins with the timescale. Here is an environmental history extending millions of years before the supposed creation of the entire Universe, reconstructed from physical evidence rather than ancient storytelling. The study does not investigate creationist claims, but its findings belong to the immense body of evidence those claims must somehow explain away. Compressing this history into a few thousand years does not explain it; it discards the chronology that makes the evidence intelligible.

Creationism Refuted - Homo Erectus Genes In Modern Humans Via Denisovans

ChatGPT-6 Astra

Ancient tooth proteins suggest ‘Homo erectus’ may have left a genetic legacy in people today

One of the difficulties creationists face when trying to squeeze human origins into the Genesis story is that the evidence keeps revealing a history far richer than their mythology allows. Instead of a single founding couple appearing a few thousand years ago, we find an extended human family, with populations diverging, migrating and sometimes exchanging genes. Now, ancient proteins preserved in fossil teeth suggest that even Homo erectus may have left a genetic legacy in some people alive today.

In a paper published in Nature, researchers report enamel proteins recovered from six Homo erectus teeth from three Chinese sites, dating to approximately 400,000 years ago. They identified two shared variants in the enamel protein ameloblastin. One distinguishes these specimens from other sampled human lineages; the other also occurs in Denisovans, with its corresponding genetic variant present in some modern humans.

The intriguing possibility is that this variant passed from a population related to these Homo erectus individuals into Denisovans, and subsequently into Homo sapiens. This is a proposed route of inheritance, not a recovered Homo erectus genome or proof of direct mating between Homo erectus and our own species. Further molecular evidence will be needed to clarify the relationship.

However, cuckoo finches do not mimic the rich olive-green eggs (top left) laid by some tawny-flanked prinia females. The new study suggests that a genetic constraint in cuckoo finches may account for their apparent inability to mimic this host egg type.

Source: University of Cambridge (2022).

An intelligent designer worth its salt would presumably avoid improving one feature by compromising another, then introducing further modifications to compensate for the damage. Yet this is precisely the sort of outcome we should expect from evolution: adaptations that work well enough to spread, carrying disadvantages with them because natural selection cannot separate every useful change from its genetic baggage. The African cuckoo-finch, Anomalospiza imberbis, provides a particularly revealing example.

Cuckoo-finches are brood parasites: they lay their eggs in other birds’ nests and leave the hosts to rear their offspring. Their success depends partly on producing eggs that resemble those of their intended foster parents. Hosts, meanwhile, benefit from recognising and rejecting the impostors. The result is an evolutionary arms race between increasingly effective deception and increasingly effective detection — an odd arrangement to attribute to a single intelligent designer supposedly responsible for both sides.

Creationism thrives on gaps because it is easy to fool scientifically illiterate people looking for confirmation for their pre-exiting bias with a god of gaps and a false dichotomy fallacy. But one massive gap they invariably ignore is the gap between the real start of the history of life on Earth some 3.8 billion years ago and the mythical 'Creation Week' 6,000-10,000 years ago, as the Bible narrative claims. This means it's easy to refute creationist beliefs simply by discovering evidence from the long pre-'Creation Week' history.

Other gaps creationists crave are the ones that transitional fossils fill, hence creationists insistence that such transitional fossils are missing, despite them regularly being found by palaeontologists, as reported in this blog and the scientific journals. This article then will have creationists performing all manner of intellectual gymnastics to try to minimise it or ignore it altogether.

Some 195 million years ago, in what is now Yunnan, China, an early dinosaur laid eggs with a revealing combination of features: a thick organic membrane and a thin mineralised layer that had not formed a rigid, interlocking shell. These eggs pre-date the supposed creation of the Universe in the conventional young-Earth biblical chronology by almost their entire existence. They also preserve something creationists repeatedly insist is missing from the fossil record: an intermediate condition illuminating an evolutionary transition.

The fossil eggshell, named Mutabilisoolithus dawaensis, is described by Zhiyong Di and colleagues in a paper published in Nature Communications. Associated with an early-diverging sauropodomorph dinosaur, it combines flexibility with a limited degree of biomineralisation — the biological deposition of minerals. Its thin calcareous layer consists of shell units that do not interlock, while its underlying membrane is exceptionally thick. This is a soft eggshell, but “soft” does not mean entirely devoid of mineral reinforcement.

Refuting Creationism - How Our Complex Cells Evolved

From: Imachi, H., Nobu, M.K., Ishii, S. et al. (2026).

How could a comparatively simple cell give rise to the elaborate internal organisation found in the cells of animals, plants, fungi and other eukaryotes? For creationists, this is another opportunity to insert a supernatural designer into an unanswered question. For scientists, it is an invitation to investigate. A new study has now brought that investigation a significant step forward by cultivating two strains of microbes belonging to one of our closest known archaeal relatives.

The research, led by Hiroyuki Imachi and Masaru K. Nobu of the Japan Agency for Marine-Earth Science and Technology, with colleagues including Satoshi Nakagawa of Kyoto University, was published in Nature on 28 October 2026. The organisms belong to Heimdallarchaeia, within the group widely known as Asgard archaea, now formally classified as Promethearchaeota.

What makes these organisms especially informative is the combination of internal simplicity and elaborate external structures. They lack a nucleus and persistent internal membrane systems, yet produce long, branching membrane protrusions. They also depend on metabolic partnerships with other microorganisms. Their biology therefore provides a way to investigate how close associations between initially separate cells could have helped set the stage for a much more intimate evolutionary partnership.

Endosymbiosis involves one organism living inside another. In the case of eukaryotic origins, a bacterial partner eventually became the mitochondrion. The outstanding questions concern how that relationship began and how it became integrated with changes in the host cell. These new findings support scenarios in which the archaeal host was still internally simple, with much of eukaryotic cellular complexity developing during or after the establishment of that partnership.

One of the strengths of science is its willingness to leave a question open until there is enough evidence to answer it. An incomplete picture is an invitation to investigate, and an explanation that changes when new evidence emerges is a demonstration that the method is working. The developing story of the Denisovans provides an excellent example: an extinct group of humans is acquiring a clearer identity through the patient accumulation and comparison of evidence.

As a Xinhua report reproduced by the Chinese Academy of Sciences explains, Denisovans were first identified in 2010 through DNA recovered from a tiny finger bone found in Siberia. Scientists could recognise a distinct evolutionary lineage before they had much idea of what its members looked like. That imbalance between molecular knowledge and anatomical knowledge presented a problem that further discoveries and improved analytical methods could address.

Researchers Unearth Fossil Evidence of First Fully Marine Amphibian | UC Davis

Why would an omniscient designer give an animal the inherited anatomy of a four-limbed vertebrate, then adapt that anatomy for life on the seabed? Evolution has a straightforward explanation: descendants inherit structures from their ancestors, and natural selection modifies what is already available. An unrestricted designer, supposedly capable of anticipating every requirement, has no comparable constraint. Yet nature repeatedly presents us with organisms whose bodies make sense as products of history.

A newly described amphibian adds another intriguing example. According to research, published in Nature Ecology & Evolution, Gerrothorax maritimus, an armoured amphibian that lived approximately 237 million years ago, presents evidence for a fully marine existence in a group whose living representatives have no equivalent ocean-going species.

The evidence includes two remarkably complete skeletons from Guizhou Province, China, marine sediments deposited far from major land masses, and strontium isotope proportions consistent with Triassic seawater. Together, these observations support an animal that inhabited the sea, rather than a freshwater carcass that happened to wash into it.

Jurassic Giant Dipluran Reveals the evolution of Hexapods---- Nanjing Institute of Geology and Palaeontology Chinese Academy of Sciences

Another of those transitional forms that creationists insist are missing, has turned up in the fossil record — this time in the shape of a Jurassic relative of insects with an informative combination of ancestral mouthparts and developing tail pincers. Named Sinojapyx giganteus, it lived approximately 165 million years ago, presenting young-Earth creationism with two familiar problems: evidence of evolutionary transition and a chronology irreconcilable with a literal reading of Genesis.

The discovery, described in a paper in Proceedings of the Royal Society B is a fossil from the Middle Jurassic Daohugou deposits of Inner Mongolia, China. More than five centimetres long, it is the oldest confirmed dipluran and the largest fossil representative yet described. Diplurans, sometimes called two-pronged bristletails, are six-legged relatives of insects, rather than insects themselves.

Its evolutionary significance lies in the details. Living diplurans have mouthparts enclosed within the head, but those of Sinojapyx were exposed. Its paired rear appendages, known as cerci, were already pincer-like, yet remained symmetrical and lacked the small teeth characteristic of the more specialised pincers of modern japygoids. The researchers place it on the stem lineage of this living group and interpret its cerci as an intermediate condition in the evolution of sensory appendages into specialised grasping weapons.

This is what a transitional fossil actually looks like: a functioning animal with a mixture of ancestral and derived characteristics. It does not need to be an implausible hybrid of two modern species, nor must palaeontologists demonstrate that this particular species was the direct ancestor of a living one. Its significance is that it preserves an anatomical combination which helps reconstruct how later specialisations evolved. Dismissing it as “still a dipluran” would miss the point entirely: evolution within a lineage does not require its descendants to cease belonging to that lineage.

Creationism Refuted - Fish And Newts Share A Common Gene for Fin and LImb Growth - Common Origin

ChatGPT-6 Astra

The findings support a stepwise model for how the genetic program that builds vertebrate paired fins and limbs may have evolved. An ancestral Hox9–10 program may first have helped establish posterior appendages, later expanded into a broader Hox patterning system, and eventually been redeployed in anterior paired appendages.

Ancient Hox code reveals the developmental roots of vertebrate hind fins and limbs | EurekAlert!

Creationists who insist that fish and terrestrial vertebrates are separately created “kinds” have another piece of evidence to explain away. Beneath the obvious differences between a fish’s pelvic fins and an amphibian’s hindlimbs lies a shared developmental inheritance: related genes performing an essential early role in establishing the cells from which those structures develop. Evolutionary relationships are recorded not only in fossils and adult anatomy, but also in the processes that build living bodies.

This is illustrated by research led by scientists at Saitama University, Japan, published in Proceedings of the National Academy of Sciences (PNAS). The researchers investigated Hox genes, regulatory genes involved in organising the developing body. Their experiments reveal a shared requirement for members of the Hox9–10 groups at the beginning of pelvic-fin and hindlimb development.

In zebrafish, disrupting five of these genes together eliminated the detectable populations of pelvic-fin progenitor cells—the cells that would normally give rise to the developing fins—and the pelvic fins failed to form. In Iberian ribbed newts, disrupting seven related genes likewise impaired the establishment of hindlimb progenitors. These results support the inference that this developmental function was already present in the common ancestor of ray-finned and lobe-finned vertebrates, before the evolutionary separation of the lineages represented by zebrafish and newts.

The significance extends beyond the discovery that different animals use related genes. The findings help connect the genetic programme that organises the rear of the body with the programme that initiates its paired hind appendages. They are consistent with an evolutionary model in which an ancestral programme was recruited, expanded and redeployed as the developmental machinery of paired fins and limbs evolved. The experiments do not directly reconstruct that entire historical sequence, but they provide functional evidence with which to assess it.

For intelligent design creationism, the familiar difficulty is that evolutionary innovation need not involve inventing every component afresh. Existing genes and developmental relationships can acquire additional roles as evolution modifies inherited systems. Calling those systems “designed” supplies no comparable account of when, where or how the changes occurred, nor does it improve the experimental explanation.

New method reveals how virus particles can build themselves, molecule by molecule | Oxford University

One of creationism’s favourite arguments depends on treating chemistry as a lottery in which every conceivable molecular arrangement is equally likely, and the winning combination must appear in a single lucky throw. Count enough possible combinations, announce an astronomical improbability, and declare that a supernatural designer must have intervened. Apart from the obvious false dichotomy fallacy, What this argument ignores is precisely what matters: molecules have physical and chemical properties that make some interactions more likely than others, and complex structures can assemble through successive intermediate stages, in a process that parallels the trial and error of evolution.

Research by scientists at the University of Oxford provides a striking illustration. In a study published open access in Nature, the team followed the assembly of an engineered virus-like particle containing 60 protein units. Using a technique that measures molecular mass through scattered light, they tracked individual particles as they grew. The advance was being able to observe the intermediate steps of a process whose beginning and end are much easier to study.

The components initially form weak, reversible associations. Unstable arrangements can break apart, leaving their components available for further encounters. Certain closed arrangements, however, gain stability through multiple connections. These become intermediate stages from which assembly can proceed. The result is a physically constrained pathway through a huge range of possibilities, without machinery directing the placement of every component, all depending on the relative strengths and weaknesses of chemical bonds.

There is an instructive parallel here with evolution, provided we recognise its limits. Molecular assembly does not involve reproduction, inherited variation and differential reproductive success, so it is not Darwinian evolution. Nevertheless, both expose the weakness of imagining that a complex outcome must arise in one wholly random step. “Trial and error” is useful shorthand: unsuccessful arrangements need not persist, while stable intermediates can support further construction. Neither molecules nor natural selection need to anticipate the eventual result.

Too much RNA can starve cells of energy, study finds – Texas A&M Stories

What sort of omniscient designer would make a cell dependent on a molecule that, when allowed to accumulate, can damage its energy-generating machinery? Presumably, one who could foresee the problem would also be capable of avoiding it. Yet research from Texas A&M University reveals precisely this vulnerability: RNA, indispensable to the functioning of living cells, can interfere with mitochondrial energy production when its abundance escapes normal control.

The findings, published in Proceedings of the National Academy of Sciences (PNAS) concern the relationship between RNA turnover and mitochondrial function. Messenger RNA carries instructions used to manufacture proteins, but those messages must also be broken down. The researchers found that this disposal process does more than regulate gene expression: it helps protect the machinery that supplies much of a cell’s usable energy.

Working with vaccinia virus, the team found that disrupting the breakdown of RNA allowed it to accumulate and severely impaired mitochondrial respiration. Further experiments showed that excess messenger RNA and double-stranded RNA could impair mitochondria even outside intact cells. The effect therefore did not require the usual antiviral immune responses. Excess RNA reduced mitochondrial membrane potential, a crucial component of the energy gradient used to make ATP. Precisely how RNA produces this disruption remains to be established.

This is not a case of cells having no safeguards. They have elaborate systems for controlling RNA abundance. The difficulty for intelligent design is that an essential component can become a threat to another essential component, leaving the cell dependent on continual regulation and clearance. Calling the safeguards evidence of brilliant design merely invites the question of why an all-knowing, all-powerful designer chose an arrangement with this vulnerability in the first place.

There is no comparable puzzle for evolution. Natural selection has no foresight, no drawing board and no opportunity to start again with an entirely different biochemistry. It acts on heritable variation in existing systems, favouring changes whose effects improve reproductive success under prevailing conditions. Benefits can outweigh costs without eliminating them, and a mechanism that works adequately under ordinary circumstances can remain vulnerable when conditions change. This study illustrates such a vulnerability; it does not establish the precise historical trade-offs that produced it.

China’s First Cave-Dwelling Freshwater Snail Named After A Mythical Mountain God | Pensoft Blog

A tiny, eyeless snail living in a Chinese cave offers an instructive challenge to two familiar creationist assumptions: that evolution must mean increasing complexity, and that the natural world was arranged for the benefit of humans. Erhaia dijiang has neither eyes nor body pigmentation, and its existence remained unknown to science until researchers investigated its obscure underground habitat. For an animal supposedly included in a creation designed around us, it has kept a remarkably low profile.

Described by Yue-Ming He and colleagues in Subterranean Biology, the species was discovered in a cave in Yuxi City, Yunnan Province, at an altitude of 2,062 metres. It is reported as China's first recorded freshwater cave snail. Its translucent shell, unpigmented body and absence of eyes are characteristic of an animal specialised for subterranean life. Appropriately, its name honours Di Jiang, a faceless being from Chinese mythology.

The evolutionary lesson is straightforward: evolution has no obligation to produce increasingly elaborate organisms. It can involve the reduction or loss of structures, just as it can produce new structures or modify existing ones. Eyes are useful where there is light to see by; in permanent darkness, their usual advantage disappears. Selection maintaining functional eyes can consequently weaken, allowing mutations that impair them to persist. Where reduced investment in unnecessary structures improves reproductive success, natural selection can also favour that reduction. The precise contributions of these processes have not been established for this particular snail, but its eyeless condition fits a familiar pattern of evolution in subterranean animals.

Comparable reductions occur in many parasites, including the loss of digestive structures in animals that absorb nutrients from their hosts. This is not evolution going backwards: evolution has no predetermined destination from which to retreat. Nor does losing one organ mean that an animal has become simpler in every respect. It means that particular features have changed within a particular ecological setting. Calling such changes “degeneration”, as creationists often do, does not place them outside evolutionary biology or explain them away.

Tiny fossils reveal a missing chapter of ocean life after Snowball Earth

More than 600 million years before the supposed creation of Earth in a literal reading of Genesis, marine communities were already living through the aftermath of a planetary ice age. Their fossilised remains now provide another inconvenient glimpse of the immense history that young-Earth creationism requires its followers to dismiss. This was a world with an evolutionary past of its own, long before the appearance of familiar animals, let alone humans and their origin myths.

A study by Qin Ye of the China University of Geosciences in Wuhan and colleagues, published in Communications Biology, describes an assemblage of microscopic and larger fossils from Ancangping in Hubei province, South China. The researchers identified 35 species of organic-walled microfossils known as acritarchs, together with six broad forms of macroscopic fossils. Preserved together, these remains provide an unusually useful window into communities that included both organisms living in the water column and algae growing on the seabed.

The assemblage is provisionally dated to approximately 620–610 million years ago. That places it around 15–25 million years after the end of the Marinoan glaciation, one of the extreme climatic episodes associated with “Snowball Earth”, when ice extended into tropical latitudes. “After” therefore needs to be understood on a geological timescale: even the interval between the thaw and these organisms exceeds the entire young-Earth creationist chronology many thousands of times over.

“Peculiar” new species of Jurassic squid found in Wyoming

Some 160 million years ago, a peculiar, thick-bodied relative of modern squid inhabited the sea that covered parts of what is now Wyoming. That alone places it inconveniently far outside the few thousand years allowed by a literal reading of Genesis. Now, two rare fossils have revealed that this animal was also a late-surviving representative of an ancient belemnite lineage — another small but revealing piece of an evolutionary history that creationism requires its followers to deny.

The newly described species, Wyoteuthis linsterorum, is the subject of a paper in Papers in Palaeontology. Although the headline calls it a Jurassic squid, it was a belemnite: a member of an extinct group of squid-like cephalopods. Its most striking feature was its exceptionally broad internal shell component, known as the rostrum or guard. Where familiar belemnite guards resemble slender bullets, these specimens are unusually stout, earning their owner the distinction of having the thickest known belemnite guards.

The fossils come from the Sundance Formation and date to the Oxfordian stage of the Late Jurassic. Examination of their external features and CT scans of their interiors led the researchers to assign the animal to the Megateuthididae, a family that had largely disappeared earlier in the Jurassic. Rather than representing a newly created form appearing from nowhere, Wyoteuthis appears to have been a surviving offshoot of an older evolutionary lineage, persisting in a regional refuge after its relatives had declined elsewhere.

For young-Earth creationism, the chronological problem is straightforward. An animal living approximately 160 million years ago cannot be accommodated within a universe supposedly created just 6,000–10,000 years ago. Nor does calling its remains a product of Noah’s Flood explain away the geological succession in which they occur. The problem is not merely the existence of a marine fossil on dry land, but its place within an ordered history of changing environments and successive assemblages of organisms.

Refuting Creationism - How Evolution Explains The Nightjar's Wing - No Magic Needed

Nightjar wings reveal a trade-off between hunting slowly and travelling far | Lund University

Evolution does not produce organisms that are perfect at everything. Natural selection acts on inherited variation, and an improvement in one function can come at a cost to another. A bird that must both migrate over long distances and catch insects in slow, manoeuvrable flight faces competing aerodynamic demands. The European nightjar, Caprimulgus europaeus, provides a revealing example of how these demands can produce a workable compromise.

As described in a news release from Lund University, the nightjar travels between Europe and southern Africa, yet uses the same wings to pursue flying insects at low speeds. Efficient travelling and slow-speed hunting do not necessarily favour identical wing shapes. Features that help the bird remain airborne while moving slowly can impose an aerodynamic penalty when it flies faster.

The research, published in PLOS Biology, investigated this compromise by measuring the airflow behind nightjars flying in a wind tunnel. At cruising speeds, the researchers detected an unusual double wingtip vortex associated with less efficient lift generation. They interpret this as a cost of the bird’s broad, slotted wingtips: a shape likely to help generate lift during slow flight and hovering, but which produces a less favourable distribution of lift at higher speeds.

Footprints in the (white) sand: Humans experienced abrupt environmental shifts during the last ice age | University of Arizona News

More than 20,000 years before the present, people were walking along a lakeshore in what is now New Mexico, leaving footprints that would eventually become a serious inconvenience for biblical literalists. At White Sands National Park, those tracks preserve evidence of human lives during the Last Glacial Maximum — long before the supposed creation of the Universe in the chronology favoured by young-Earth creationists, let alone their alleged global flood and subsequent repopulation of the Americas.

Now, research published open access in Science Advances reaffirms that the footprints date to approximately 23,500–21,700 years ago. It also reconstructs a changing landscape: retreating Lake Otero, shifts from conifer forest towards steppe vegetation, and episodes of severe aridity. Some changes occurred within a human lifetime. These were people inhabiting a dynamic Ice Age environment, leaving their tracks alongside those of mammoths, giant sloths and dire wolves.

The history of the dating is itself an instructive example of how science works. The original age estimates, announced in 2021, attracted criticism because they relied on seeds from aquatic plants. Such plants can absorb dissolved ancient carbon, potentially making radiocarbon dates appear older than they really are. That was a legitimate methodological objection, and the appropriate response was to test it. A follow-up study reported in 2023 used pollen from terrestrial conifers and an independent technique that measures when mineral grains were last exposed to sunlight. Both supported the ancient chronology.
