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.

Antelope collagen found in 60,000-year-old ochre offers clues to early human practices

Some 60,000 years ago, humans occupying a shelter in southern Africa left behind traces of activities that modern science is only now learning to recover. An ochre-rich surface at Kilpdrift Shelter preserves proteins identified as belonging to the common eland, Taurotragus oryx, a large African antelope.

For those who insist that the entire Universe was created only a few thousand years ago, the difficulty begins before we even consider what these people were doing: they were already there, handling animal materials and ochre, tens of thousands of years before the supposed creation of their ancestors.

The discovery is described in a paper published in Proceedings of the Royal Society B by researchers from Kyushu University, the University of Bergen and the University of Copenhagen.

What that contribution represents remains an open question. Animal-derived material may have been deliberately mixed with ochre, or the surface may preserve traces of eland hides treated with it. The finding establishes an association between ochre and animal material; it does not, by itself, establish a particular recipe, a hide-processing technique or a symbolic purpose. Nevertheless, it opens a valuable window onto the technical, and possibly symbolic, behaviour of early Homo sapiens, particularly in environments where ancient DNA is poorly preserved.

Here, then, is another example of archaeology producing inconvenient evidence for biblical literalism simply by investigating the human past. The researchers are asking what people did, which materials they used and how surviving molecules can help reconstruct their activities. There is room for uncertainty about the precise activity recorded on this ancient surface. That uncertainty is not permission to compress 60,000 years of human history into a creationist chronology of six to ten thousand years.

Creationism in Crisis - Yet Another Of Those 'Non-Existent' Transitional Fossils - From 165 Million Years Before 'Creation Week'

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.

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.

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.

Creationism Refuted - Dinosaur Tracks Record Transition From Crawling to Bipedalism

From Sprawling to Bipedalism: How Locomotion Evolved in Dinosaur Ancestors - Museum für Naturkunde Berlin

One of the familiar refrains of creationism is that the fossil record contains no transitional forms. Yet transitions need not be preserved only in bones: sometimes, animals left evidence of evolutionary change in the footprints they made. A new study of ancient reptile tracks reveals a stepwise acquisition of features associated with upright locomotion — changes that helped establish the conditions for the later evolution of two-legged movement in dinosaurs and their close relatives.

The research, by Lorenzo Marchetti of the Museum für Naturkunde Berlin and Hendrik Klein of the Saurierwelt Paläontologisches Museum, is published in Palaeontology, concerns early archosauriforms, members of the wider evolutionary group that includes archosaurs — dinosaurs, pterosaurs, crocodilians and their relatives. Their history extends back into the Late Permian, more than 250 million years ago: already an insurmountable chronological problem for a literal reading of Genesis.

Marchetti and Klein re-examined footprints from the Val Gardena Sandstone Formation of northern Italy, including previously undescribed specimens, and recognised a distinctive track type, which they named Pachychirotherium gardenaensis. This is a name for the fossil traces, rather than a newly identified species of skeletal animal. Comparisons with fossil feet suggest that their makers were early archosauriforms with an anatomy resembling that of erythrosuchids.

The wider comparison with Permian and Triassic tracks is particularly revealing. Late Permian forms retain evidence consistent with sprawling locomotion; some Early Triassic forms show transitional characteristics; and a fully erect stance probably emerged during the Middle Triassic. Increasing reliance on the toes, changes in toe proportions and a reduction in the relative size of the forefoot impressions accompanied this evolutionary transition. These features were assembled progressively, rather than appearing together as a completed package.

Not All Early Birds Evolved Toward Better Flight, Jurassic Fossil Suggests----Chinese Academy of Sciences

Creationists who insist that there are no transitional fossils might wish that palaeontologists would stop finding animals that refuse to respect their imaginary boundaries. A newly described Jurassic bird from China is another such inconvenience: an evolutionary mosaic combining bird-like features with conspicuously dinosaurian anatomy. And, to compound the difficulty for Bible literalists, it lived approximately 150 million years ago — long before their supposed ‘Creation Week’.

The animal, Yuezhuornis yangyuanensis, discovered in the Late Jurassic Zhenghe Fauna of Fujian Province, is described in a paper published in Nature. This crow-sized animal possessed bird-like pelvic and hindlimb features alongside serrated teeth and a hyperextensible second toe bearing a sickle-shaped claw — a combination reminiscent of its close dinosaurian relatives.

Its unusually short forelimbs provide another intriguing part of the story. Analyses of its limb proportions strongly support a terrestrial, flightless lifestyle, despite its placement within Avialae, the evolutionary group containing living birds and their closest extinct relatives. The researchers interpret it as evidence of exceptionally early flight loss. That interpretation necessarily involves reconstructing ancestral capabilities: the fossil provides anatomical evidence about how this animal lived, rather than a direct record of either its behaviour or its ancestors’ flight.

This matters because evolution has no destination. Early birds were not obliged to become progressively better flying machines, any more than every mammalian lineage was obliged to become a bat. Natural selection favours traits according to their consequences in particular environments; it does not work towards a predetermined ideal. A lineage exploiting opportunities on the ground could follow a different evolutionary course from one increasingly dependent on flight.

UK dinosaur fossil identified as new long-clawed predator | UCL News

Palaeontologists do not need to set out to refute biblical creationism. They merely need to investigate the history of life, and the evidence does the job for them. Another example comes from the Isle of Wight, where a fossil has revealed a previously unrecognised predatory dinosaur that lived about 120 million years ago — long before the supposed ‘Creation Week’ of a literal reading of Genesis. While creationists struggle to squeeze the history of an entire planet into a few thousand years, researchers are reconstructing the evolutionary relationships and geographical movements of animals separated from us by immense stretches of geological time.

The fundamental problem creationists have created for themselves is that, because there is vastly more history pre-'Creation Week' than there is post-'Creation Week', by several orders of magnitude, virtually every palaeontological, geological and archaeological discovery incidentally refutes creationism, so the most risible and dishonest mental gymnastics have to be invoked to dismiss it all, and creationists end up looking both intellectually and morally bankrupt.

For example, as described in a study, published in Royal Society Open Science, a team led by University College London (UCL) researchers has identified Invictibellatrix amberina, the first recognised European member of a group of carnivorous dinosaurs known as megaraptorans. The discovery concerns a partial skull acquired by the Natural History Museum in 1924. CT scanning and anatomical comparisons have now revealed its significance. From its relatives, the researchers infer an animal around three to four metres long, probably feathered and equipped with substantial grasping arms and curved claws.

The discovery also helps fill a geographical gap in the group’s known distribution, supporting the hypothesis that megaraptorans dispersed from Asia through Europe towards the southern continents. This is the sort of question evolutionary science can investigate: how related animals diversified, where they lived, and how changing geography influenced their distribution. A fossil becomes evidence within a wider, testable account of life’s history.

New species of Jurassic crocodile had unusually slender teeth | University of Portsmouth

Some 170 million years ago, in the rivers and lakes of what is now Morocco, a crocodile relative was exploiting a feeding niche very different from that of the large-prey predators familiar today. Named Ctenosuchus tenuidens, it had a long, narrow snout armed with exceptionally slender, closely spaced teeth. For young-Earth creationists, its existence presents the familiar chronological problem: an animal was living, feeding and participating in a complex ecosystem more than 169 million years before their preferred biblical chronology allows Earth itself to have existed.

The discovery is described in a paper in the Journal of Vertebrate Paleontology by Hamzah Imran of the School of the Environment and Life Sciences, University of Portsmouth, and colleagues. The animal belonged to the thalattosuchians, an extinct group of crocodile relatives. Its delicate dentition suggests a diet of small aquatic prey, such as tiny fish, shrimps and worms, rather than large, struggling animals capable of breaking those fine teeth.

This makes the fossil particularly informative about evolutionary specialisation. Teeth are not simply more or less effective in some universal sense: their usefulness depends on what an animal eats and how it feeds. A robust tooth suited to restraining substantial prey and a fine tooth suited to retaining small organisms represent different solutions to different ecological problems. An adaptation can therefore open up one feeding opportunity while limiting another. Evolution produces such compromises because natural selection favours reproductive success under particular conditions, rather than engineering an organism that excels at everything.

New crocodile species discovered in rocks used to build the Great Sphinx | UCL News

The Great Sphinx of Giza is an ancient monument carved into something vastly more ancient: rocks recording a world that existed long before humans, let alone Egyptian civilisation. A newly recognised crocodilian from the same geological formation lived about 45 million years ago. For anyone attempting to reconcile Earth's history with a literal reading of Genesis and its young-Earth chronology, the difficulty begins with the material from which the monument itself was carved.

As UCL News reports, researchers have identified Herugavialis cairensis, an extinct gavial, or long-snouted crocodilian, from Egypt's Mokattam Formation. Its nearly complete skull was discovered in the 1920s and had long been assigned to Tomistoma, the genus containing today's false gharial. CT scanning revealed distinguishing anatomical features, including a raised ridge around the eyes, supporting its recognition as a separate genus. The findings are published in Royal Society Open Science.

This is a useful example of how science corrects itself. A fossil does not cease to be informative because it has spent a century in a museum, and an identification does not become unchallengeable merely because generations of researchers have accepted it. Better tools and renewed scrutiny can expose distinctions that earlier investigators missed. Revising the classification strengthens our understanding of evolutionary history; it does not undermine the evidence that such a history occurred.

The animal also belonged to a very different Egypt. Shallow seas covered areas that are now land, and several gavial species inhabited its coastal waters. UCL describes a wider Mediterranean history in which crocodilian diversity fluctuated alongside changes in temperature and sea level, before the region lost its crocodilians around the Mediterranean drying crisis roughly six million years ago. Even that much later episode predates the conventional young-Earth creationist date for the entire Universe by orders of magnitude.

Creationism Refuted - A 700,000-Year-Old Elephant Tooth Shows The Bible's Authors Didn't Know Their Own Local History

An elephant tooth recovered from Gesher Benot Ya'aqov (GBY-NBA) — a prehistoric site in northern Israel, where early humans made stone tools some 700,000 years ago — has enabled researchers to reconstruct a lush Pleistocene landscape of woodlands, wetlands, and waterways. The findings provide a rare glimpse into the environment shared by giant elephants and some of the region's earliest human populations.

700,000-year-old elephant tooth reveals a lost ecosystem shared by early humans in the levant | EurekAlert!

Some 700,000 years ago, in what is now northern Israel, early humans were making stone tools in a landscape shared with giant elephants and exploiting their surroundings, hundreds of thousands of years before the supposed ‘Creation Week’ of young-Earth creationism.

That alone presents an insurmountable chronological problem for anyone who insists that Genesis is a literal account of history; a problem compounded by the fact that this history occurred close to where the origin myths in Genesis were written by people who were conspicuously ignorant of even their own local history.

Now, an elephant tooth has helped researchers reconstruct something of the world those people inhabited. A study published in Quaternary Science Reviews examines remains of the extinct straight-tusked elephant, Palaeoloxodon antiquus, found alongside Acheulean handaxes and cleavers at North Bridge Acheulian–Gesher Benot Ya‘aqov. By combining CT imaging, dental wear, isotope analysis and pollen evidence from the sediments, the researchers reconstructed a mosaic of woodland, grassland, wetlands and waterways.

The resulting picture is of a resource-rich environment that could support both large mammals and early human populations. Reliable water and varied vegetation apparently helped this part of the Hula Valley function as an ecological refuge along the Levantine corridor linking Africa and Eurasia. This was an inhabited landscape with an ecological history, rather than merely a collection of ancient bones and stones.

Professor Peishu Li coauthors Nature study uncovering ancient origins of mammalian suckling and swallowing

Some 165 million years before creationists imagine Earth existed, an aquatic relative of modern mammals was already carrying anatomical equipment associated with one of our most characteristic abilities: suckling milk. A newly described fossil from Inner Mongolia, China, adds another inconvenient chapter to the evolutionary history that young-Earth creationism insists never happened. Its significance extends beyond its age, however. It also preserves a revealing combination of ancestral and more modern features — precisely the sort of transitional anatomy that creationists routinely claim is missing from the fossil record.

The animal, Megacauda sungei, is described in a new paper in Nature. It belonged to the docodonts, an extinct branch of mammaliaforms, the broader group encompassing mammals and their closest extinct relatives. Living approximately 168–163 million years ago, it had a broad, flattened tail, swimming adaptations and specialised teeth suited to an animal diet. It was a functioning, specialised inhabitant of Jurassic freshwater environments, with an evolutionary history written into its anatomy.

Particularly informative are small bony projections near the back of the palate and specialised throat bones. In living mammals, comparable structures support the muscles and soft tissues involved in swallowing and suckling. Their presence in Megacauda suggests that important components of this feeding apparatus had already evolved by the Middle Jurassic. This does not mean that the fossil identifies the first animal to produce milk, or preserves a youngster caught feeding. The inference concerns the anatomical machinery that made mammal-like suckling and swallowing possible.

Refuting Creationism - The Earliest Aquatic Mammal Complete With Transitional Features - 120 Million Years Before 'Creation Week'

Reconstruction of the semi-aquatic life of Dongoconodon platycauda

Drawn by Chen Yu.

A joint study by Professor Bi Shundong of the School of Life Sciences at Yunnan University has discovered the earliest known swimming mammal to date.

Some 120 million years before anyone imagined a six-day creation, a small mammal in what is now northeastern China was combining features that refuse to fit the tidy categories creationists would like nature to obey. Dongoconodon platycauda had adaptations for swimming, an unusual pattern of tooth replacement, and an ear apparatus that retained a connection to its lower jaw. Here was a functioning animal with a mosaic of characteristics, illustrating how evolution modifies inherited structures without waiting for an entire collection of supposedly “mammalian” features to arrive together.

The nearly complete skeleton, from the Early Cretaceous Jiufotang Formation of Liaoning Province, is described by Shundong Bi and colleagues in Nature Communications. The research is also explained in institutional reports from Nanjing University and Yunnan University, both in Chinese.

Its broad hands and feet probably supported webbing, while its flattened, tapering tail appears to have helped with steering and stability. Comparisons with the skeletons of 124 living mammal species supported a semiaquatic lifestyle. This adds to the evidence that mammals living alongside dinosaurs occupied a much wider range of ecological niches than the familiar image of small, uniformly shrew-like creatures might suggest.

Previously unknown extinct bovine species discovered in Siberia - Stockholms universitet

For young-Earth creationists, the problem with ancient DNA is that it keeps revealing histories which their preferred chronology cannot accommodate. The latest example is an extinct relative of the yak whose evolutionary separation from living yaks began at least 400,000 years ago — long before the supposed “Creation Week” of a literal reading of Genesis. Its existence has emerged from fragments of Siberian bone too incomplete to identify by their shape, but which retained something much more informative: genetic evidence of a lost branch of the bovine family tree.

In a study published in Current Biology, Jonas Oppenheimer, Alexandre Gilardet and colleagues report 20 ancient nuclear genomes from Denisova Cave and other sites in southern Siberia, spanning more than 200,000 years. The lineage, provisionally known as “yak X”, had previously been recognised from mitochondrial DNA. The new analysis provides much broader genetic evidence that it represented a distinct species that effectively separated from the lineage leading to living yaks by about 250,000 years ago.

This was no static population inhabiting an unchanging world. The genomes reveal a demographic decline and suggest population turnover, accompanied by reduced genetic diversity, around the last interglacial, approximately 130,000–115,000 years ago. Warming may have disrupted the distribution of these cold-adapted animals; an earlier warm interval may also have helped isolate populations during their initial divergence. Those climatic explanations remain hypotheses, but the genetic evidence provides a record against which they can be tested. The youngest specimen analysed is about 27,000 years old; precisely when, and why, the lineage subsequently disappeared remains unknown.

There is an equally instructive lesson in the researchers’ caution. Although they interpret the genomic evidence as identifying a separate species, they have not simply attached a new formal species name to these fragmentary remains. Comparisons with previously described yak-like fossils are needed to establish whether the genetic lineage corresponds to an animal already recognised from its anatomy. Discovering a previously unrecognised genetic history and resolving its taxonomic identity are related but distinct tasks. Scientific confidence in one does not require pretending that the other has already been settled.

For creationism, meanwhile, calling the animal “just another member of the cattle kind” does nothing to resolve the chronological problem. The evidence concerns a branching history of populations, divergence and eventual extinction extending across hundreds of thousands of years. Evolutionary biology supplies the framework for reconstructing that history and asking further questions about it. Compressing everything into a few thousand years would require an alternative explanation for the genetic relationships, the ages of the remains and the succession of populations — not merely a biblical label applied after the evidence has been collected.

Revolutionary Feathered Dinosaur Discovery in China Suggests Flight Evolved Multiple Times : ScienceAlert

For creationists who insist that complex adaptations could only have appeared as complete, purpose-built packages, another feathered dinosaur has provided an awkward piece of evidence. Evolution does not require a finished flight apparatus to materialise in a single miraculous leap. It can modify inherited structures, combine them in new ways, and produce similar adaptations along different branches of the family tree. A newly described dinosaur from China adds evidence that even among the close relatives of birds, there was more than one evolutionary route towards an aerial lifestyle.

In a paper published in Nature Communications, Xuri Wang and colleagues describe Norellraptor barsboldi, a small microraptorine dinosaur from the Lower Cretaceous Jiufotang Formation of Liaoning, north-eastern China. Its remarkably complete, 57-centimetre skeleton preserves traces of plumage, including on its forelimbs and hindlimbs. It belonged to the group of feathered dinosaurs famous for their four-winged forms: evolutionary relatives of birds, rather than evidence that modern birds appeared fully formed and unrelated to other dinosaurs.

The crucial finding concerns the sequence in which adaptations arose. The researchers’ evolutionary analysis indicates that approximately 30 per cent of the derived anatomical features identified in microraptorine evolution also evolved independently in the bird lineage. However, they appeared in different orders. This supports the gradual assembly of flight-associated anatomy under different selective pressures, rather than the inheritance of an already completed flight apparatus from a common ancestor.

Fossils confirm human ancestors first appearance, News, La Trobe University

Two million years ago, southern Africa was home to different human relatives sharing the same landscape and following different evolutionary trajectories. That is the picture strengthened by newly described fossils from Drimolen Main Quarry in South Africa’s Cradle of Humankind. For creationists, the difficulties begin with the date: these hominins lived almost two million years before the supposed magical creation of the Universe out of nothing in a literal reading of Genesis. But the evidence also challenges the familiar caricature of human evolution as a single procession of increasingly human creatures, marching towards a predetermined destination.

In a paper published in Annals of Human Biology, Jesse M. Martin and colleagues describe 18 previously undescribed cranial and mandibular specimens from Drimolen. Among them is DNH 127, an adult skull fragment attributed to Homo erectus. This provides valuable support for the earlier identification of DNH 134, a young child’s partial skull from the same site. Identifying a species from an immature individual can be difficult because some diagnostic features develop during growth; an adult specimen provides an additional test of that interpretation.

The significance is therefore corroboration: DNH 127 strengthens the case that Homo erectus was present in South Africa approximately 2.04–1.95 million years ago. It does not, by itself, establish that the species originated there. The earliest fossil yet recognised is evidence of a species’ presence at a particular place and time, rather than a birth certificate identifying its evolutionary birthplace.

Famous "First Reptile" Fossil Wasn’t a Reptile After All | AMNH

One of the supposed earliest reptiles has lost its place in the reptile family tree — and, in doing so, has provided a revealing example of how evolution works and how science improves its understanding of it. For creationists hoping that a revised classification means evolutionary biology is collapsing, the disappointment is twofold: the fossil remains approximately 345 million years old, and its newly revealed anatomy makes the transition towards life on land more interesting, not less evident.

The animal is Westlothiana lizziae, affectionately known as “Lizzie”, a small, superficially lizard-like vertebrate discovered in Scotland in 1984. Its limbs and apparently clawed digits helped establish its reputation as an early representative of the evolutionary transition towards amniotes — the group encompassing mammals and reptiles, including birds. However, interpreting a crushed fossil from its exposed surfaces has limitations. Structures hidden inside the rock can tell a different story, as researchers have now demonstrated using powerful X-ray scans at the European Synchrotron Radiation Facility in Grenoble, France.

The research, published on 30 September in Nature reveals an unexpected combination: a skull retaining ancient anatomical features, bony supports for internal gills, and a mouth bearing thousands of tiny teeth. These are indications of an aquatic or amphibious animal. The researchers place Westlothiana among stem tetrapods, on an evolutionary branch outside the group comprising living amphibians and amniotes and their last common ancestor.

Yet Lizzie also possessed five-digit feet and superficially claw-like finger and toe bones. That combination is the significant point. Features associated with terrestrial vertebrates were already appearing in animals that retained substantial adaptations to life in water. This is an example of mosaic evolution: different parts of the body change at different rates, producing combinations that do not fit the tidy categories we recognise among living animals. It also means that claw-like impressions in ancient trackways cannot, by themselves, establish that the animals making them were early amniotes.

Mother of amphibians: New species of proto-amphibian described by two student scientists, named in honor of their moms - Field Museum

One of the recurring problems for young-Earth creationism is that Earth’s history contains so much life before the supposed beginning of Earth’s history. A newly recognised fossil species from Illinois adds another example: a small, amphibian-like animal that lived approximately 309 million years ago, when the area around modern Chicago was a swampy river delta. That places it more than 300 million years before the creation event that biblical literalists insist accounts for all life on Earth. Explaining away a discrepancy of that magnitude requires rather more than pointing to an uncertainty in a scientific paper.

The animal is Jeanerpeton mazonensis, described by Allison J. Sefcovic, Payton J. Kohlberg and colleagues in a new paper in the Journal of Vertebrate Paleontology. Its recognition resulted from a fresh examination of a fossil already held in a museum collection. Previously assigned to Amphibamus grandiceps, the specimen proved sufficiently different in its skull and skeleton to warrant a genus and species of its own. The authors also suggest that other known specimens conceal more diversity among these early amphibamiforms than has previously been recognised.

The fossil comes from the exceptionally productive Mazon Creek deposits. Its preservation includes a body outline, scales, tiny abdominal skeletal elements called gastralia, and even impressions of the eyes. The genus honours the two student lead authors’ mothers, both named Jean. This is a reminder that important discoveries can begin with someone taking a closer look at a specimen collected long ago.

Of particular interest are structures previously interpreted as toe pads resembling those of living amphibians. Alongside the skeletal anatomy, such features help researchers investigate the combinations of characteristics present in these ancient animals. That does not establish Jeanerpeton as the direct ancestor of modern frogs or salamanders: resemblance and evolutionary relationship are not proof of direct ancestry. Its significance lies in adding another anatomically distinctive animal to the record against which explanations of amphibian evolution must be tested.

UNM researcher helps uncover recurring climate regimes linked to elevated extinction risk | UNM UCAM Newsroom

One of the more ridiculous of creationist claims is that Earth was perfectly ‘fine-tuned’ for life by an omniscient, omnibenevolent designer. Ridiculous because a mere glance at the reality should tell them that natural disasters such as earthquakes, seismic activity and flash-floods regularly devastate huge areas and kill vast numbers of people. The rose-tinted view requires a remarkably selective reading of the planet’s history: admire the organisms alive today, but overlook the environmental upheavals that wiped out so many of their predecessors. A world capable of supporting life is not necessarily a world designed to protect it, and the geological record provides abundant evidence of that distinction.

New research, paper, published in Nature Communications, adds another dimension to this problem. An international team, including UNM palaeobiologist Corinne “Cori” Myers, examined approximately 539 million years of Earth’s history and identified five major, persistent ‘mega-climate’ regimes. Transitions between these regimes were associated with heightened vulnerability in the biosphere and elevated extinction risk. The history emerging from this analysis is one of prolonged climatic states punctuated by potentially dangerous reorganisations.

The study brings together carbon and oxygen isotope records, statistical analyses and a conceptual model of the interacting climate and carbon cycle. The researchers compared the environmental patterns with a measure of biological vulnerability incorporating fossil diversity and the rates at which groups appeared and disappeared. Their findings suggest that the consequences of an environmental disturbance depend partly on the state of the planetary system it affects: a perturbation can help push that system into a different regime, with serious consequences for its inhabitants.

This does not establish that every mass extinction had the same cause, or that each climate transition inevitably produced one. Volcanism, asteroid impacts and their associated environmental effects remain essential parts of the explanation. The study instead offers a broader framework for understanding why some episodes of disruption coincided with particularly severe biological crises. Its central finding concerns an association between changing climate–carbon regimes and increased vulnerability, rather than a single universal extinction mechanism.

For the creationist argument, however, the difficulty is plain. If Earth’s suitability for living organisms is to count as evidence of benevolent design, what are we to make of its capacity to become catastrophically unsuitable for organisms already living here? Invoking a designer’s concern for life while dismissing the destruction of entire evolutionary lineages is an exercise in choosing the evidence to fit the conclusion. Survival receives the credit; extinction disappears into the small print.
