There is, of course, no let-up in the steady stream of bad news for creationists to ignore in 2026, and today is no exception. This time the problem comes from archaeology and concerns events taking place toward the end of the very long span of Earth’s history that preceded creationism’s so-called *Creation Week*. The news is that the diversification of domestic dogs, descended from domesticated wolves, had already begun at least 11,000 years ago — long before anything resembling the modern concept of dog “breeds”.
The evidence is presented in a paper published in Science by a team led by palaeontologists from the University of Exeter and France’s Centre National de la Recherche Scientifique (CNRS). The researchers analysed 643 modern and archaeological canid skulls—including recognised breeds, village dogs, and wolves—spanning the last 50,000 years. In both geographical scope and time depth, it is the largest and most comprehensive study of its kind to date.
Using a technique known as geometric morphometrics, the team demonstrated that by the Mesolithic and Neolithic periods dogs already displayed a striking range of shapes and sizes. This diversity almost certainly reflects their varied roles in early human societies, from hunting and herding to guarding and companionship, rather than anything resembling systematic modern breeding.
All of this directly contradicts the claim in Genesis that animals were created fully formed for mankind’s exclusive use by an omnipotent and omniscient creator. Had that been the case, dogs would not require modification to make them fit for different purposes, nor would the archaeological record preserve clear evidence of their gradual evolutionary divergence from an ancestral wolf population. Instead, the evidence shows — unambiguously — that modern dogs are the product of an evolutionary process in which human-mediated selection played a central role, carried out by people who themselves existed long before the biblical timeline allows.
We are only three days into 2026 and already creationism is facing an avalanche of new evidence against it and in favour of evolution on an ancient Earth in a vastly older Universe — directly contradicting the Bronze Age origin myths that creationists cling to with the desperation of a drunk clutching a lamppost.
The latest blow comes from the New York University Department of Anthropology, where a team of researchers led by Associate Professor Scott Williams, working with colleagues from the University of Washington, Chaffey College, and the University of Chicago, have carried out a detailed re-examination of fossil remains attributed to Sahelanthropus tchadensis. Their analysis provides strong evidence that this species was bipedal and shared several key skeletal characteristics with later bipedal hominins, including the australopithecines and members of the genus Homo.
Sahelanthropus tchadensis was discovered in the early 2000s, and its place in human evolution has been debated ever since. Some researchers argued it might represent an extinct ape rather than a stem hominin. Evidence for habitual bipedalism, however, strongly favours the latter interpretation, making S. tchadensis the earliest known human ancestor currently identified in the fossil record.
As such, it becomes yet another example of the transitional species that creationists continue to insist do not exist, often under the mistaken belief that Charles Darwin — whom they treat as the final authority on all matters evolutionary — admitted that the absence of transitional forms was a serious problem for his theory. In reality, Darwin explicitly predicted that such fossils would eventually be found, and the subsequent century and a half of palaeontology has repeatedly confirmed that prediction.
The discovery is of a point of attachment on the femur of a ligament only found in bipedal hominins. The importance of bipedalism in human evolution cannot be overstated. Habitual upright walking is one of the defining characteristics that separates hominins from other apes, reflecting a fundamental shift in anatomy, locomotion, and behaviour. It requires extensive reorganisation of the skeleton, including changes to the position of the foramen magnum, the curvature of the spine, the shape of the pelvis, the proportions of the limbs, and the structure of the feet. Because these adaptations are complex, interdependent, and leave clear signatures in fossilised bones, bipedalism is not a trivial or ambiguous trait. Evidence for it in Sahelanthropus tchadensis therefore places this species firmly on the human lineage and pushes the origin of upright walking — and with it the human evolutionary trajectory — back far earlier than creationist models allow.
One reliable way to recognise that the Bible is the product of ancient ignorance is simply to compare its claims with what science has since revealed. Nowhere is this more apparent than in Genesis, which turns out to be a ludicrously simplistic attempt to explain the origins of the universe and life on Earth. Its compressed timescale cannot possibly accommodate what we now know about the age of the universe, the age of our planet, the deep history of life, or—most conspicuously—the emergence of human cultures and the migration of humans across every continent except Antarctica, as revealed by the archaeological record.
The gap between biblical mythology and reality is so vast that it cannot plausibly be rescued as allegory or metaphor, and the evidence continues to accumulate relentlessly, with nothing being discovered that remotely validates the biblical account.
The year 2025 ended badly for creationism with the discovery of a 37-million-year-old transitional snake fossil from southern England, and 2026 has begun no better. A new book, The Oldest Rocks on Earth, by Simon Lamb, Associate Professor of Geophysics at Victoria University of Wellington, describes the surface conditions on Earth when life first emerged more than 3.5 billion years ago—conditions utterly incompatible with the biblical creation narrative.
The research behind this book is summarised in an article in The Conversation, also by Associate Professor Lamb. That article is reproduced here under a Creative Commons licence, reformatted for stylistic consistency.
Ancient African bedrock reveals the violent beginnings of life on our blue planet
You have probably seen the images of the surface of Mars, beamed back by NASA’s rovers. What if there were a time machine capable of roaming Earth during its remote geological past, perhaps even going right back to its beginnings, beaming back pictures of similar quality?
This is not science fiction. In remote corners of the world, geologists have found tiny relics of Earth’s very ancient surface.
I have been part of this scientific endeavour, looking at the treasure trove of information in the bedrock of the Makhonjwa Mountains in South Africa and the adjacent small kingdom of Eswatini.
These rocks reach back more than three quarters of the way through our planet’s long history of nearly 4.6 billion years. In my new book, The Oldest Rocks on Earth, I describe the graphic images “beamed back” by this geological time machine.
Beneath the remote and rugged landscape of the Makhonjwa Mountains, in Eswatini, is a bedrock that holds a record of Earth’s surface from 3.2 to 3.5 billion years ago, when our planet was about a quarter of the way through its history.
The ancient rocks reveal a world with extensive oceans and intense volcanic activity on the sea floor.
Deep beneath the crust, Earth was much hotter than today, giving rise to an unusual white-hot magma, rich in elements from its interior. Huge volumes of super-heated water continually gushed out of underwater cracks, building up chimneys of valuable metals. And life was thriving around these undersea vents.
Volcanic islands rose up from the ocean depths. These were dangerous places. Pools of hot bubbling mud dotted their shores, and clouds of volcanic ash periodically exploded from volcanic craters.
Life was already there, forming microbial mats in the sheltered nearshore waters.
Periodically, large earthquakes violently shook the bedrock, triggering submarine avalanches that cascaded down into the deep ocean, creating vast jumbles of rock on the sea floor. Giant asteroid impacts disturbed this world, but crucially, did not extinguish it.
Deep-seated forces were pushing up new land, creating the early continents.
Ocean waves moved back and forth on sandy beaches along coastlines with bays, lagoons, inlets and estuaries, with tides similar to those today.
During floods, large rivers brought muddy water from the continental interior. Farther in the distance, their headwaters drained a mountainous terrain, often enveloped in thick cloud.
It was a blue planet because, like today, the oceans scattered light in the blue part of the colour spectrum.
But the atmosphere contained a lethal cocktail of gases, including high concentrations of methane and carbon dioxide. These greenhouse gases kept the surface at the right temperature for liquid water, at a time when astrophysicists calculate the Sun was much weaker. But there was no oxygen.
The earliest life forms were anaerobic microbes, although brightly coloured – pink or purple have been proposed.
Oceania today
Oceania, in the southwestern Pacific, may illustrate best what this early world was like. Here, the ocean is peppered with volcanic islands and small continents, rocked by great earthquakes where tectonic plates rub against each other. There are even clues to how life began.
The 2022 eruption of the Hunga volcano, near Tonga, created a mushroom cloud of ash that burst out of the ocean and reached up into space with an estimated energy of a 60-megaton atomic bomb. It generated more than 200,000 lightning strikes and left behind a deep underwater crater filled with a chemical soup derived from numerous underwater hot vents.
Experiments show that lightning strikes can trigger the synthesis of basic organic molecules needed by living organisms. Millions of Hunga-like eruptions on early Earth would have created myriad opportunities to kick start the chemistry of life in underwater volcanic craters – life was born out of extreme geological violence.
Staying blue
Going back in time beyond the Makhonjwa Mountains, we still find evidence for oceans, life and, I argue, plate tectonics. Earth became blue within the first tenth of its history.
Mars and Venus may have started this way, too. But our planet uniquely lies in the so-called Goldilocks Zone, receiving just the right amount of solar energy to avoid becoming a boiling Venusian hell or freezing Martian world.
It is also big enough to have a magnetic field and pull of gravity sufficient to retain its atmosphere. And right at the start, a dramatic collision with a Mars-sized asteroid spalled off our Moon, stabilising Earth’s spin axis so that day and night were less extreme.
Finally, the biochemistry of living organisms may have played a key role in keeping Earth this way by helping the bedrock absorb greenhouse gases in the face of a steadily warming Sun.
We must not be the first to let Earth lose its distinctive life-giving blue, a colour so wonderfully referred to in the Siswati language of Eswatini as luhlata lwesibhakabhaka, literally “green like the sky”.

What emerges from this work is not a minor disagreement over interpretation, nor a gap that can be papered over with metaphor or selective reading. The world described by geology, geochemistry and planetary science is fundamentally incompatible with the universe imagined by the authors of Genesis. Earth was not a gentle, pre-prepared garden awaiting life, but a violent, unstable planet shaped by impacts, volcanism and relentless geological recycling over billions of years. Life did not appear suddenly by decree, but clawed its way into existence under conditions that would have been lethal to almost anything alive today.
This matters because creationism depends on the claim that its sacred text offers a privileged insight into reality. Yet when examined against the physical evidence locked into Earth’s oldest rocks, Genesis is not merely wrong in detail—it is wrong in kind. Its authors had no conception of deep time, planetary formation, plate tectonics, or the chemical and physical constraints under which life emerged. Their account reflects the worldview of Bronze Age pastoral societies, not hidden wisdom awaiting modern confirmation.
As discoveries like these continue to accumulate, the creationist position becomes ever more untenable. There is no convergence, no narrowing of the gap, no sense in which science is “catching up” with scripture. Instead, each new insight into Earth’s early history widens the chasm between myth and reality. The Bible does not describe the world we inhabit, the planet on which life evolved, or the processes that made our existence possible—and no amount of reinterpretation can change that.
This article struck a chord with me — not primarily because it refutes creationism, although it certainly does that by presenting evidence that simply should not exist if the biblical flood genocide story contained even a kernel of truth. Such evidence ought either to have been swept away entirely or buried beneath a thick layer of flood-deposited silt containing a chaotic jumble of animal and plant fossils from unrelated landmasses. It was neither.
What resonated more personally, however, is that I have just published a novel in which a clan of Neolithic hunter-gatherers forms a close association with wolves, with the animals playing a central role in both their hunting strategies and their folklore. In the novel, The Way of the Wolf: A Stone Age Epic — the second volume in the Ice Age Tales series — Almora is raised alongside a wolf cub that becomes her inseparable guide and protector. This relationship gives rise to several versions of a mythologised hunt in which the wolf, Sharma, saves the day and defends the hunters. Together with her Neanderthal partner, Tanu, Almora later leads a group of exiles who encounter a clan already familiar with these legends, and who have begun adopting abandoned wolf cubs and raising them as part of the community.
It is fiction, of course — but a deliberately realistic depiction of how wolves could have been domesticated through mutual benefit, cooperation, and prolonged social contact with humans.
The article itself concerns the discovery by researchers at the Francis Crick Institute, Stockholm University, the University of Aberdeen, and the University of East Anglia of wolf remains on a remote Baltic island that could only have been transported there by boat. Isotopic analysis shows that these wolves consumed the same food as the humans, and skeletal pathology in one individual indicates long-term care. The findings are reported in a research paper published in Proceedings of the National Academy of Sciences (PNAS).
Scientists at the Scripps Institute have discovered a defective DNA repair mechanism that would normally trigger cell death but which, paradoxically, keeps cancer cells alive. They have recently published their findings, open access, in Cell Reports. It is exactly the sort of biochemical complexity that creationists routinely mistake for evidence of intelligent design, having been led to believe that well-designed systems must be highly complex. In reality, good intelligent design is minimally complex: complexity increases the risk of failure, is harder to maintain, and is more energetically costly.
The DNA “code” is one of creationism’s favourite props for its familiar ignorance-plus-incredulity-therefore-God-did-it argument — a textbook god-of-the-gaps false dichotomy. Yet even a superficial look beneath the metaphor reveals that DNA replication and repair are very far from the flawless perfection we would expect from an omniscient, omnipotent and omnibenevolent deity — especially when it comes to its supposedly special creation, humankind. What we actually observe is a fragile, error-prone system patched together by evolutionary history rather than foresight.
The system is only needed in the first place because cell replication in multicellular organisms remains essentially identical to that of single-celled organisms. Despite the fact that the benefits of multicellularity arise from cell specialisation into tissues and organs with discrete functions — each requiring only a tiny fraction of the genome — every cell is forced to copy the entire DNA complement every time it divides. This vast waste of energy and resources serves only to multiply the probability of error, and errors are not rare anomalies but routine occurrences. This is not the signature of intelligent design.
The Scripps Institute team have shown that some cancer cells survive precisely because the normal high-fidelity repair system fails. When that happens, a crude backup mechanism takes over — an emergency repair process that is little more than a biological kludge and which introduces further errors as it works. It is rather like calling out an emergency plumber who fixes one leak by installing a long section of pipe riddled with smaller leaks. Would anyone describe that as intelligent workmanship?
Normally, creationists seize on any concentration of animal fossils that can be attributed to flooding as supposed “evidence” for their favourite Bronze Age myth of a global genocide. On that basis, they should be delighted by recent news from Romania describing a rich deposit of dinosaur fossils that appears to have accumulated as a result of flooding in the Hațeg Basin.
There is, however, a serious snag. These fossils occur in deposits dated to around 72 million years ago — tens of millions of years before creationists believe the Earth even existed — and the evidence points clearly to repeated local flooding events, not a single global catastrophe.
The discovery of the fossil site is reported in the journal PLOS ONE by the Valiora Dinosaur Research Group, a collaboration of Hungarian and Romanian palaeontologists co-led by Gábor Botfalvai and Zoltán Csiki-Sava of the Institute of Geography and Earth Sciences, Department of Palaeontology, ELTE Eötvös Loránd University, Budapest, Hungary.
This paper will have creationists searching for reasons to dismiss evidence that would, if they were prepared to accept it honestly, force them to concede that their beliefs are wrong. It reports a discovery by researchers at Stellenbosch University showing that dinosaur eggshells can be dated with a high degree of precision using an already well-established technique: uranium–lead (U–Pb) radiometric dating.
Until now, U–Pb dating has been most famously applied to zircon crystals in volcanic ash, where the age can be determined by measuring the ratio of radioactive uranium isotopes to the stable lead isotopes produced by their decay. In this study, however, the same underlying principles are applied to calcite crystals preserved in dinosaur eggshells.
Researchers from the University of New South Wales (UNSW), Sydney, Australia, have identified DNA switches that help control how astrocytes work. These are brain cells that support neurons and are known to play a role in Alzheimer’s disease. They have just published their findings in Nature Neuroscience.
Firstly, there is the embarrassment that the cause of Alzheimer’s is indistinguishable from Michael J. Behe’s favourite ‘proof’ of intelligent design — irreducible complexity — in that all the elements must be present for Alzheimer’s to occur.
Secondly, there is the discovery by the Australian team of which triggers ‘switch on’ which genes that affect the astrocytes implicated in Alzheimer’s. These switches are embedded in the 98% of the human genome that is non-coding, or so-called ‘junk’ DNA. Since they can be separated from the genes they regulate by thousands of base pairs, it has been notoriously difficult to identify which switches control which genes. Now, using CRISPR, the team have identified around 150 of these regulatory elements.
The existence of this non-coding DNA has long been an embarrassment for creationists, who have been unable to explain why an intelligent designer would produce so much DNA that does not contain the roughly 20,000 genes that actually code for proteins. Why such prolific waste, adding massively to the risk of errors that can result in cancer?
The creationist response has been to conflate the terms ‘non-coding’ and ‘non-functional’, and then proclaim this ‘functional DNA’ as intelligently designed — reducing, but by no means eliminating, the amount of ‘junk’ they still have to explain away. Of course, ‘non-coding’ does not mean ‘not transcribed’, only that the RNA does not code for a functional protein. However, this non-coding but functional DNA does play a role in gene expression, in that the resulting RNA can act as controls or ‘switches’ that turn genes on and off.
So, creationists — having triumphantly waved ‘functional, non-coding DNA’ as evidence for intelligent design after all — are now presented with the fact that it is part of the ‘irreducible’ cause of Alzheimer’s, and probably the cause of many other diseases with a genetic basis.
Two researchers at McGill University, Montréal, Québec, Canada, have uncovered evidence of an ecosystem teeming with giant marine predators some 130 million years ago. The largest of these predators could, quite literally, have eaten something the size of a modern orca as little more than a snack. This will make depressing reading for creationists, not only because it all happened deep in the long pre-“Creation Week” history of life on Earth, but because the evolutionary arms races that led to these giants are precisely what the theory of evolution by natural selection predicts.
It doesn’t get any easier for creationists. Just because it’s Christmas week doesn’t mean the awkward facts are going to go away, or that scientists are going to stop uncovering more of them. No matter what they post on social media; no matter how loudly they shout; or how fervently they gather on Sundays to collectively drown out their doubts, Santa is not going to deliver evidence that the Bronze Age creation myths in the Bible contain even a grain of historical truth. The problem is that truth remains true whether a creationist believes it or not, and regardless of whether their parents believed it. No amount of looking the other way or pretending the facts aren’t there will ever change that.
The palaeontologists reached their conclusions by reconstructing an ecosystem network for all known animal fossils from the Paja Formation in central Colombia. They used body sizes, feeding adaptations, and comparisons with modern animals, and then validated the results against one of the most detailed present-day marine ecosystem networks available: the living Caribbean ecosystem, which they used as a reference. The Paja ecosystem thrived with plesiosaurs, ichthyosaurs, and abundant invertebrates, giving rise to one of the most intricate marine food webs known. This complexity emerged as sea levels rose and Earth’s climate warmed during the Mesozoic era, including the Cretaceous, triggering an explosion of marine biodiversity.

Palaeontologists at the College of Graduate Studies, Glendale Campus of Midwestern University in Arizona, have reconstructed the head and face of an early Homo erectus specimen, DAN5, from Gona in the Afar region of Ethiopia on the Horn of Africa. In doing so, they have uncovered several unexpected features that should trouble any creationist who understands their significance. The research has just been published open access in Nature Communications.
Creationism requires its adherents to imagine that there are no intermediate fossils showing a transition from the common Homo/Pan ancestor to modern Homo sapiens, whom they claim were created as a single couple just a few thousand years ago with a flawless genome designed by an omniscient, omnipotent creator. The descendants of such a couple would, of course, show no genetic variation, because both the perfect genome and its replication machinery would operate flawlessly. No gene variants could ever arise.
The reality, however, is very different. Not only are there vast numbers of fossils documenting a continuum from the common Homo/Pan ancestor of around six million years ago, but there is also so much variation among them that it has become increasingly difficult to force them into a simple, linear sequence. Instead, human evolution is beginning to resemble a tangled bush rather than a neat progression.
The newly reconstructed face of the Ethiopian Homo erectus is no exception. It displays a mosaic of more primitive facial traits alongside features characteristic of the H. erectus populations believed to have spread out of Africa in the first of several waves of hominin migration into Eurasia. The most plausible explanation is that the Ethiopian population descended from an earlier expansion within Africa, became isolated in the Afar region, and retained its primitive characteristics while other populations continued to evolve towards the more derived Eurasian form.
The broader picture that has emerged in recent years—particularly since it became clear that H. sapiens, Neanderthals, and Denisovans formed an interbreeding complex that contributed to modern non-African humans—is one of repeated expansion into new environments, evolution in isolation, and subsequent genetic remixing as populations came back into contact. DAN5 represents just one of these populations, which appears to have evolved in isolation for some 300,000 years.
Not only is this timescale utterly incompatible with the idea of the special creation of H. sapiens 6,000–10,000 years ago, but the sheer existence of this degree of variation is also irreconcilable with the notion of a flawless, designed human genome. Even allowing for old-earth creationist claims that a biblical “day” may represent an elastic number of millions of years, the problem remains: a highly variable genome must still be explained as the product of perfect design. A flawless genome created by an omniscient, omnipotent creator should, moreover, have been robust enough to withstand interference following “the Fall” — an event such a creator would necessarily have foreseen, particularly if it also created the conditions for that fall and the other creative agency involved (Isaiah 45:7).
As usual, creationists seem to prefer the conclusion that their supposed intelligent creator was incompetent—either unaware of the future, indifferent to it, or powerless to prevent it—rather than accept the far more parsimonious explanation: that modern Homo sapiens are the product of a long, complex evolutionary history from more primitive beginnings, in which no divine intervention is required.
Origins of Homo erectus
Homo erectus
Homo erectus appears in the fossil record around 1.9–2.0 million years ago, emerging from earlier African Homo populations, most likely derived from Homo habilis–like ancestors. Many researchers distinguish early African forms as Homo ergaster, reserving H. erectus sensu stricto for later Asian populations, although this is a taxonomic preference rather than a settled fact.
Key features of early H. erectus include:
A substantial increase in brain size (typically 600–900 cm³ initially, later exceeding 1,000 cm³)
A long, low cranial vault with pronounced brow ridges
A modern human–like body plan, with long legs and shorter arms
Clear association with Acheulean stone tools and likely habitual fire use (by ~1 million years ago)
Crucially, H. erectus was the first hominin to disperse widely beyond Africa, reaching:
The Caucasus (Dmanisi) by ~1.8 Ma
Southeast Asia (Java) by ~1.6 Ma
China (Zhoukoudian) by ~0.8–0.7 Ma
This makes H. erectus not a single, static species, but a long-lived, geographically structured lineage.
Homo erectus as a population complex
Rather than a uniform species, H. erectus is best understood as a metapopulation:
African populations
Western Eurasian populations
East and Southeast Asian populations
These groups experienced repeated range expansions, isolation, local adaptation, and partial gene flow, producing the mosaic anatomy seen in fossils such as DAN5.
This population structure is critical for understanding later human evolution.
Relationship to later Homo species
Neanderthal (H. neanderthalensis)
From H. erectus to H. heidelbergensis
By around 700–600 thousand years ago, some H. erectus-derived populations—probably in Africa—had evolved into forms often grouped as Homo heidelbergensis (or H. rhodesiensis for African material).
These hominins had:
Larger brains (1,100–1,300 cm³)
Reduced facial prognathism
Continued Acheulean and early Middle Stone Age technologies
They represent a transitional grade, not a sharp speciation event.
Divergence of Neanderthals, Denisovans, and modern humans
Genetic and fossil evidence indicates the following broad pattern:
~550–600 ka: A heidelbergensis-like population splits
African branch → modern Homo sapiens
Eurasian branch → Neanderthals and Denisovans
Neanderthals
Evolved primarily in western Eurasia
Adapted to cold climates
Distinctive cranial morphology
Contributed ~1–2% of DNA to all non-African modern humans
Denisovans
Known mostly from genetic data, with sparse fossils (Denisova Cave)
Closely related to Neanderthals but genetically distinct
Contributed genes to Melanesians, Aboriginal Australians, and parts of East and Southeast Asia, including variants affecting altitude adaptation (e.g. EPAS1)
Modern Homo sapiens
Emerged in Africa by ~300 ka
Retained genetic continuity with earlier African populations
Dispersed out of Africa multiple times, beginning ~70–60 ka
Interbred repeatedly with Neanderthals and Denisovans
The key point: no clean branching tree
Human evolution is reticulate, not linear:
Species boundaries were porous
Gene flow occurred repeatedly
Populations diverged, adapted, re-merged, and diverged again
Homo erectus is not a side branch that “went extinct”, but a foundational grade from which multiple later lineages emerged. DAN5 fits neatly into this framework: a locally isolated erectus population retaining ancestral traits while others continued evolving elsewhere.
Why this matters
This picture:
Explains mosaic anatomy in fossils
Accounts for genetic admixture in living humans
Makes sense of long timescales and geographic diversity
Is incompatible with any model of recent, perfect, single-pair creation
Instead, it shows that our species is the outcome of millions of years of population dynamics, not a single moment of design.
A new fossil face sheds light on early migrations of ancient human ancestorA New Fossil Face Sheds Light on Early Migrations of Ancient Human Ancestor
A 1.5-million-year-old fossil from Gona, Ethiopia reveals new details about the first hominin species to disperse from Africa.
Summary: Virtual reassembly of teeth and fossil bone fragments reveals a beautifully preserved face of a 1.5-million-year-old human ancestor—the first complete Early Pleistocene hominin cranium from the Horn of Africa. This fossil, from Gona, Ethiopia, hints at a surprisingly archaic face in the earliest human ancestors to migrate out of Africa.
A team of international scientists, led by Dr. Karen Baab, a paleoanthropologist at the College of Graduate Studies, Glendale Campus of Midwestern University in Arizona, produced a virtual reconstruction of the face of early Homo erectus. The 1.5 to 1.6 million-year-old fossil, called DAN5, was found at the site of Gona, in the Afar region of Ethiopia. This surprisingly archaic face yields new insights into the first species to spread across Africa and Eurasia. The team’s findings are being published in Nature Communications.
We already knew that the DAN5 fossil had a small brain, but this new reconstruction shows that the face is also more primitive than classic African Homo erectus of the same antiquity. One explanation is that the Gona population retained the anatomy of the population that originally migrated out of Africa approximately 300,000 years earlier.

Gona, Ethiopia
The Gona Paleoanthropological Research Project in the Afar of Ethiopia is co-directed by Dr. Sileshi Semaw (Centro Nacional de Investigación sobre la Evolución Humana, Spain) and Dr. Michael Rogers (Southern Connecticut State University). Gona has yielded hominin fossils that are older than 6.3 million years ago, and stone tools spanning the last 2.6 million years of human evolution. The newly presented hominin reconstruction includes a fossil brain case (previously described in 2020) and smaller fragments of the face belonging to a single individual called DAN5 dated to between 1.6 and 1.5 million years ago. The face fragments (and teeth) have now been reassembled using virtual techniques to generate the most complete skull of a fossil human from the Horn of Africa in this time period. The DAN5 fossil is assigned to Homo erectus, a long-lived species found throughout Africa, Asia, and Europe after approximately 1.8 million years ago.
How did the scientists reconstruct the DAN5 fossil?
The researchers used high-resolution micro-CT scans of the four major fragments of the face, which were recovered during the 2000 fieldwork at Gona. 3D models of the fragments were generated from the CT scans. The face fragments were then re-pieced together on a computer screen, and the teeth were fit into the upper jaw where possible. The final step was “attaching” the face to the braincase to produce a mostly complete cranium. This reconstruction took about a year and went through several iterations before arriving at the final version.
Dr. Baab, who was responsible for the reconstruction, described this as “a very complicated 3D puzzle, and one where you do not know the exact outcome in advance. Fortunately, we do know how faces fit together in general, so we were not starting from scratch.”
What did scientists conclude?
This new study shows that the Gona population 1.5 million years ago had a mix of typical Homo erectus characters concentrated in its braincase, but more ancestral features of the face and teeth normally only seen in earlier species. For example, the bridge of the nose is quite flat, and the molars are large. Scientists determined this by comparing the size and shape of the DAN5 face and teeth with other fossils of the same geological age, as well as older and younger ones. A similar combination of traits was documented previously in Eurasia, but this is the first fossil to show this combination of traits inside Africa, challenging the idea that Homo erectus evolved outside of the continent.
I'll never forget the shock I felt when Dr. Baab first showed me the reconstructed face and jaw. The oldest fossils belonging to Homo erectus are from Africa, and the new fossil reconstruction shows that transitional fossils also existed there, so it makes sense that this species emerged on the African continent,” says Dr. Baab. “But the DAN5 fossil postdates the initial exit from Africa, so other interpretations are possible.

It is remarkable that the DAN5 Homo erectus was making both simple Oldowan stone tools and early Acheulian handaxes, among the earliest evidence for the two stone tool traditions to be found directly associated with a hominin fossil.

Future Research
The researchers are hoping to compare this fossil to the earliest human fossils from Europe, including fossils assigned to Homo erectus but also a distinct species, Homo antecessor, both dated to approximately one million years ago.
Comparing DAN5 to these fossils will not only deepen our understanding of facial variability within Homo erectus but also shed light on how the species adapted and evolved.

There is also potential to test alternative evolutionary scenarios, such as genetic admixture between two species, as seen in later human evolution among Neanderthals, modern humans and “Denisovans.” For example, maybe DAN5 represents the result of admixture between classic African Homo erectus and the earlier Homo habilis species.
We’re going to need several more fossils dated between one to two million years ago to sort this out.
Abstract
The African Early Pleistocene is a time of evolutionary change and techno-behavioral innovation in human prehistory that sees the advent of our own genus, Homo, from earlier australopithecine ancestors by 2.8-2.3 million years ago. This was followed by the origin and dispersal of Homo erectus sensu lato across Africa and Eurasia between ~ 2.0 and 1.1 Ma and the emergence of both large-brained (e.g., Bodo, Kabwe) and small-brained (e.g., H. naledi) lineages in the Middle Pleistocene of Africa. Here we present a newly reconstructed face of the DAN5/P1 cranium from Gona, Ethiopia (1.6-1.5 Ma) that, in conjunction with the cranial vault, is a mostly complete Early Pleistocene Homo cranium from the Horn of Africa. Morphometric analyses demonstrate a combination of H. erectus-like cranial traits and basal Homo-like facial and dental features combined with a small brain size in DAN5/P1. The presence of such a morphological mosaic contemporaneous with or postdating the emergence of the indisputable H. erectus craniodental complex around 1.6 Ma implies an intricate evolutionary transition from early Homo to H. erectus. This finding also supports a long persistence of small-brained, plesiomorphic Homo group(s) alongside other Homo groups that experienced continued encephalization through the Early to Middle Pleistocene of Africa.
Introduction
The oldest fossils assigned to our genus are ~2.8 million years old (Myr) from Ethiopia and signal a long history of Homo evolution in the Rift Valley1,2,3. There is evidence of multiple Homo lineages in Africa by 2.0–1.9 million years ago (Ma) and an archaeological and paleontological record of expansion to more temperate habitats in the Caucasus and Asia between 2.0 and 1.8 Ma4 (Fig. 1). The last appearance datum for the more archaicHomo habilis species (or “1813 group”) is ~1.67 (OH 13) or ~1.44 Ma, if KNM-ER 42703 is correctly attributed to H. habilis5, which is uncertain6. The archetypal early African Homo erectus fossils from Kenya (i.e., KNM-ER 3733, 3883; and the adolescent KNM-WT 15000) already present a suite of traits that distinguish them from early Homo taxa by 1.6–1.5 Ma, including larger brains and bodies, smaller postcanine dentition, more pronounced cranial superstructures (e.g., projecting and tall brow ridges), a relatively wide midface and nasal aperture, deep palate, and projecting nasal bridge1,6,7,8,9,10,11. The only evidence for H. erectus sensu lato in Africa before 1.8 Ma are fragmentary or juvenile fossils12,13,14, while fossils expressing both ancestral H. habilis and more derived H. erectus s.l. morphological traits are only known from Dmanisi, Georgia at 1.77 Ma15,16. Thus, H. erectus emerged from basal Homo between 2.0 and 1.6 million years ago, but when, where (Africa or Eurasia), and how it occurred remain unclear. An expanded fossil record also documents significant variation in endocranial 17,18 and craniofacial6,8 and dentognathic morphology19,20 throughout the Early Pleistocene, which extends to the Middle Pleistocene with the addition of small-brained Homo lineages to the human tree.

The solid bars of the timeline indicate well-established first and last appearance data; the horizontal stripes indicate possible extensions of the time range based on fragmentary or juvenile fossils. Diagonal lines signal earlier archaeological presence in those regions. The question mark indicates a possible date of <1.49 Ma for the Mojokerto, Indonesia site cf.22,23,24,25. The horizontal gray bar represents the time range associated with DAN5/P1. Colors on the map indicate presence of fossils matching taxa or geographic groups of H. erectus as indicated in the timeline.

All surface renderings visualized at FOV 0° (parallel). Map was generated in “rnaturalearth” package68 for R.
The initial announcement of DAN5/P1 assigned it to H. erectus on the basis of derived neurocranial traits21. Subsequent analyses of neurocranial shape and endocranial morphology confirmed affinity with H. erectus but also noted similarities to early (pre-erectus) Homo fossils such as KNM-ER 181317,18. Only limited information about the partial maxilla and dentition was presented in the original description21. Yet, facial and dental traits are increasingly important in early Homo systematics, given overlap in brain size among closely related hominins6,8,22. The DAN5/P1 fossil is a rare opportunity to evaluate neurocranial, facial, and dental anatomy in a single Early Pleistocene Homo fossil and thus has significant implications for this discussion.
Here we present a new cranial reconstruction of the 1.6–1.5 Myr DAN5/P1 fossil from Gona, Ethiopia. This study demonstrates that the small-brained adult DAN5/P1 fossil (598 cm321) presents a previously undocumented combination of early Homo and H. erectus features in an African fossil.
Taken together, the evidence leaves little room for the idea that Homo erectus was a dead-end curiosity, neatly replaced by something entirely new. Instead, it represents a long-lived, widely dispersed, and internally diverse population complex that provided the evolutionary substrate from which later human lineages emerged. Its descendants were not produced by sudden leaps or special creation events, but by the ordinary, observable processes of population divergence, isolation, and adaptation acting over deep time.
Modern Homo sapiens, Neanderthals, and Denisovans did not arise as separate “kinds”, nor did they follow clean, branching paths. They represent regional outcomes of this erectus-derived heritage, shaped by geography, climate, and repeated episodes of contact and interbreeding. The genetic legacy of those interactions is still present in living humans today, providing independent confirmation of what the fossil record has long been indicating.
What emerges is not a ladder of progress but a dynamic, reticulated history: populations spreading, fragmenting, evolving in isolation, and reconnecting again. Fossils such as DAN5 are not anomalies to be explained away; they are exactly what we should expect from evolution operating on structured populations across continents and hundreds of thousands of years.
For creationism, this is deeply inconvenient. For evolutionary biology, it is precisely the kind of rich, internally consistent picture that arises when multiple independent lines of evidence converge on the same conclusion: humanity is the product of a long, complex evolutionary history, not a recent act of design.
In another major embarrassment for those creationists who understand it, researchers at the Gladstone Institutes and Stanford University have developed a method for linking the genome of a cell to diseases caused by specific gene variants. They have recently published their findings, open access, in Nature.
Creationists insist that the human genome was intelligently designed, with every outcome the result of “complex specified information” which, according to Discovery Institute Fellow William A. Dembski, constitutes definitive evidence of intelligent design. If this were true, it would follow that genes which cause disease were intelligently designed to cause those diseases.
The difficulty deepens for creationists when one considers that many diseases involve multiple genes, sometimes hundreds or even thousands, all of which must possess the “correct” variants for the disease to emerge. In other words, some diseases not only depend on Dembski’s “complex specified genetic information”, but also conform to Michael J. Behe’s proposed hallmark of intelligent design: irreducible complexity.
Unless creationists invoke an additional creator—one over whom their reputedly omnipotent and omniscient god has no control—their supposedly intelligent designer must have deliberately created these gene variants to produce the suffering they cause.
By contrast, the evolutionary explanation requires no such mental gymnastics. The existence of genetic variants is exactly what evolutionary theory predicts, and provided such variants remain rare within a population, there is little selective pressure to remove them. A genome produced by an omniscient, perfect designer, however, would contain no such variants: the original design would be flawless, as would the mechanisms responsible for replicating it. The very existence of gene variants is therefore evidence against intelligent design.
The technique developed by the research team is sensitive enough to examine the entire genome and determine which genes influence which cell types. This makes it possible to identify which genes contribute to particular diseases. In cases where a single gene is involved, this can be relatively straightforward, but where many genes are implicated, it can be extremely difficult to disentangle their individual effects—precisely the problem this new technique helps to overcome.
Having recently watched a grey squirrel carefully plot a route through a line of trees, I was struck by the sophistication of its behaviour. It was not simply moving at random. It clearly knew where it wanted to go and was able to take into account such factors as how much slender branches would bend under its weight, how wide a gap it could safely jump, and—perhaps most importantly—exactly where it was within its own mental map of the environment. It is difficult to see how such behaviour could be possible in a creature that was not conscious and, to some degree, self-aware.
In animal psychology, there is now little doubt that many vertebrates possess some level of self-awareness and therefore consciousness. The remaining debate has centred not on whether consciousness exists in non-human animals, but on how it arose. The fact that consciousness is found across a wide range of vertebrates, and even in molluscs such as cephalopods, suggests either that it originated in a remote common ancestor or that it evolved independently multiple times through convergence. Either way, this strongly points to an evolutionary origin.
According to two papers published in a special edition of the journal Philosophical Transactions of the Royal Society B, by working groups led by Professors Albert Newen and Onur Güntürkün at Ruhr University Bochum in Germany, consciousness can indeed be explained as the outcome of an evolutionary process, with each step conferring a selective advantage. Moreover, consciousness only makes sense as an evolved biological function. The two open-access papers can be found here and here.
This work is bound to provoke another bout of denialism among creationists, for whom consciousness remains one of the standard “impossible to explain without supernatural intelligence” fallback arguments. As with abiogenesis and the Big Bang, the reasoning typically amounts to: “Science hasn’t explained it and I don’t understand how it could, therefore God did it.” This false dichotomy conveniently removes any obligation to provide evidence in support of the supernatural claim. Creationists also like to flatter themselves that consciousness is a uniquely human trait and thus evidence of special creation. In scientific terms, however, this does not even rise to the level of a hypothesis: it proposes no mechanism, makes no testable predictions, and is unfalsifiable by design. It is, in essence, wishful thinking rooted in the belief that the Universe is obliged to conform to personal expectations.
By contrast, the Ruhr University team have identified three distinct levels of consciousness and demonstrated the evolutionary advantage of each, drawing on detailed studies of birds that show parallel forms of consciousness to those seen in humans. These levels are:
Basic arousal — such as the perception of pain, which signals that harm is occurring and that corrective action is required.
General alertness — awareness of the broader environment, allowing threats and opportunities to be recognised and responded to appropriately.
Reflexive (self-)consciousness — the ability to place oneself within an environment, learn from past experience, anticipate future outcomes, and formulate an action plan; in other words, to construct a narrative with oneself as a participant.
Among flowering plants, few groups look as alien as Balanophora. These strange, tuberous parasites lack leaves, lack roots in any conventional sense, and contain no chlorophyll. They spend almost their entire lives embedded within the roots of other plants, emerging only briefly to flower. To a casual observer, they barely resemble plants at all — and that superficial oddity has sometimes been exploited by creationists as evidence that they represent a fundamentally distinct “kind”.
In reality, Balanophora are not evolutionary outliers. They are a textbook example of what happens when natural selection acts over long periods on a parasitic lineage.
Where Balanophora fit in the plant kingdom
Molecular phylogenetics places Balanophora firmly within the angiosperms, in the order Santalales. This is the same order that includes mistletoes, sandalwood, and a range of hemi- and holoparasitic plants. Their closest relatives are photosynthetic or partially parasitic species, providing a clear evolutionary gradient from free-living autotrophs to obligate parasites.
This placement is not controversial. It is supported by nuclear, mitochondrial, and plastid gene sequences, as well as by reproductive and developmental traits. Balanophora are deeply nested within the flowering plant family tree, not perched mysteriously at its base.
They are not an early-diverging angiosperm lineage. They sit well within the eudicots, inside an order dominated by parasitism. This is exactly what evolution predicts for a lineage that became parasitic rather than being created as such.
Creationism would expect either:
A distinct, isolated “kind”, or
No consistent phylogenetic signal at all
Instead, Balanophora fall precisely where descent with modification says they should.
Transitional relatives exist
Within Santalales you can trace a graded series:
Fully photosynthetic plants
Root parasites that still photosynthesise
Plants with reduced photosynthesis
Fully holoparasitic forms like Balanophora
This gradient is phylogenetic, not just ecological. It maps cleanly onto the tree.
Plastid phylogeny seals the case
Even though Balanophora plastids are massively reduced, the genes that remain:
Cluster with chloroplast genes of Santalales
Show derived mutations consistent with long-term loss of photosynthesis
Cannot be explained as independently created organelles
In other words, the plastids themselves remember their ancestry.
Creationism, which insists on fixed, separately created categories, has no principled way to explain why these plants fall exactly where evolution predicts they should.
Species of Balanophora are parasitic plants that live underground and emerge above ground only during the flowering season — and some species even reproduce exclusively asexually. This collage shows species studied to establish how the plants of that group relate to each other, how they modified their plastids and how their reproduction fits into their ecology.
A recently published paper in New Phytologist on the biology of the parasitic plants *Balanophora*, by three botanists from the Okinawa Institute of Science and Technology, Japan, together with Kenji Suetsugu of Kobe University, should cause consternation in creationist circles — if only they were not so practised at dismissing any evidence that contradicts their superstition.
Not only does the study highlight the well-known problem of parasitism, which creationists typically attempt to wave aside by invoking “The Fall” — thereby exposing any claim that creationism is a genuine science rather than a form of Christian fundamentalism as a lie — it also reveals that the evolution of this group of plants has involved a loss of complexity, coupled with the repurposing of redundant structures. The result is what creationists themselves would describe as irreducible complexity, accompanied by precisely the kind of “complex specified genetic information” that William A. Dembski insists should be regarded as evidence for intelligent design.
Then there is the problem of an overly complex solution, in that, instead of simply giving the plants the genes they need, some essential genes have been included in cell organelles These are clearly repurposed chloroplasts that no longer perform photosynthesis, produced by an evolutionary process that creationists deny - leaving them to explain why an intelligent designer opted for such an overly complex solution.
Finally, the findings rely entirely on the Theory of Evolution to explain and make sense of the observations, with no hint of any need to invoke the supernatural magic upon which creationism depends — despite repeated assurances from creationist cult leaders to their followers that such a moment is imminent, a promise they have been making for over half a century.
Dugongs and manatees — the surviving members of the order Sirenia — are among the most revealing mammals when it comes to understanding evolution. Fully aquatic yet air-breathing, specialised yet constrained by their ancestry, they provide one of the clearest examples of how complex organisms arise through gradual modification rather than sudden creation.
Unlike whales, which are now well known as a textbook evolutionary transition, sirenians are less familiar to the public. That makes them especially valuable, because their fossil record is remarkably complete, their evolutionary trajectory is straightforward, and their genetic relationships were discovered independently of their anatomy. Taken together, they present a problem for creationism that cannot be explained away.
Terrestrial origins.
The earliest known sirenians lived around 50 million years ago and were unmistakably terrestrial or semi-aquatic mammals.
