Geometric and mathematical patterns on Halafian pottery.
Scientists have once again — almost certainly unintentionally — produced evidence that the Bible is profoundly wrong about human history. This time it comes in the form of pottery shards dating back more than 8,000 years to the Halafian culture of northern Mesopotamia (c. 6200–5500 BCE). These artefacts show that people were not only producing sophisticated ceramics, but were decorating them with complex mathematical patterns long before the formal invention of numbers and counting systems.
According to the biblical account of global history, Earth was subjected to a catastrophic genocidal reset, inflicted in a fit of pique by a vengeful god who had failed to anticipate how his creation would turn out. Rather than simply eliminating humanity and starting again with a corrected design, this deity allegedly chose to preserve the same flawed model in a wooden boat while drowning everything else beneath a flood so deep it covered the highest mountains. The implicit hope appears to have been that repeating the experiment would somehow yield a different result.
As implausible as that story already is, we now possess a vast body of archaeological and palaeontological evidence showing not only that Earth is vastly older than the biblical narrative allows, but that this supposed catastrophic reset never occurred. The latter is demonstrated by the existence of civilisations that predate the alleged flood and continue uninterrupted through it, as though it never happened at all. Their material remains include artefacts that would have been completely destroyed or displaced by such a deluge, and settlement sites that show no sign of burial beneath a chaotic, fossil-bearing sedimentary layer containing mixed local and foreign species.
No such global layer exists. Instead, human artefacts are found precisely where they were made and used, unaffected by any mythical torrent scouring the planet clean.
The designs on the Halafian pottery themselves are particularly revealing. They include repeating patterns — for example, binary progressions such as 2, 4, 8, 16, 32 — suggesting that this culture possessed systematic ways of dividing land or goods to ensure equitable distribution.

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.

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. Surface renderings of the best-preserved regional representatives of archaic or small-brained Homo fossils (beginning at top and continuing clockwise): D2700, KNM-ER 1813, KNM-ER 1470, KNM-ER 3733, SK 847, OH 24, KNM-WT 15000, and DAN5/P1. 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.
As I’ve pointed out many times, 99.9975% of Earth’s history took place before the period in which creationists—treating the Bible as literal historical truth—believe the planet itself existed. It is remarkable how effectively biblical literalists manage to ignore, distort, or otherwise dismiss almost the entire body of geological, archaeological, and palaeontological evidence in order to cling to the easily refuted notion of a 6,000–10,000-year-old Earth and a global genocidal flood supposedly occurring about 4,000 years ago.
Unsurprisingly, discoveries such as the one below make no impression whatsoever on committed creationists.
Now archaeologists from Aarhus University, working with colleagues from the National Museum of Denmark as well as teams from Germany, Sweden, and France, have uncovered yet another piece of evidence destined for creationist dismissal: blue pigment on a stone artefact dating from around 13,000 years ago. Their findings were recently published in Antiquity.
Not only should this archaeology not exist at all if the biblical timeline were correct, but even if it had somehow escaped the supposed global flood, it would necessarily be buried beneath a thick, worldwide layer of sediment containing a chaotic mixture of fossil plants and animals from disconnected continents. No such layer has ever been found anywhere on Earth. A truly global flood, as described in Genesis, would have left unmistakable and ubiquitous geological signatures. It did not.
The blue pigment was discovered on a shaped, concave stone originally thought to be an oil lamp but now believed to have served as a mixing palette. Until now, only black and red pigments had been identified on Palaeolithic artefacts, leading archaeologists to assume these were the only colours available. The presence of blue pigment suggests something more nuanced: selective use of colours for different purposes, with blue likely used primarily for body decoration or dyeing clothing—activities that rarely leave direct archaeological traces.
56 million years ago, in that vast expanse of pre–‘Creation Week’ history when 99.975% of Earth’s story unfolded — long before creationists imagine the Universe even existed — an event occurred that gives the lie to the claim that their putative designer created Earth as a safe and stable planet, finely tuned for the existence of (human) life. Earth’s temperature rose by roughly 6 °C as the amount of carbon in the atmosphere increased dramatically.
The cause of this, the Palaeocene–Eocene Thermal Maximum (PETM), lay in the disruption of one of Earth’s major feedback systems. Plants sequester carbon through photosynthesis and lock it into their tissues, but that system was pushed out of balance until a new equilibrium eventually formed. It took some 70,000–100,000 years for the planet to recover.
The problem was that higher temperatures caused many plants to fail because they had evolved for cooler conditions, and evolution proceeds far too slowly to cope with rapid environmental change. As plant productivity collapsed, less carbon was sequestered, which in turn drove temperatures higher — a classic positive feedback loop, triggered by a relatively small initial shift.
The worrying parallel today is that the current rate of anthropogenic warming is around ten times greater than at the onset of the PETM.
How we know this — and how the PETM reshaped climate and the terrestrial biosphere — is explored in a paper by an international team of scientists, published open access (in unedited form) in Nature Communications.

56 million years ago, the Earth suddenly heated up – and many plants stopped working properly
Forest life in the Paleocene-Eocene Thermal Maximum
As we show in new research published in Nature Communications, one consequence was that many of the world’s plants could no longer thrive. As a result, they soaked up less carbon from the atmosphere, which may have contributed to another interesting thing about this prehistoric planetary heatwave: it lasted more than 100,000 years.
Today Earth is warming around ten times faster than it did 56 million years ago, which may make it even harder for modern plants to adapt.
Rewinding 56 million years
Plants can help regulate the climate through a process known as carbon sequestration. This involves capturing carbon dioxide from the atmosphere via photosynthesis and storing it in their leaves, wood and roots.
However, abrupt global warming may temporarily impact this regulating function.
Investigating how Earth’s vegetation responded to the rapid global warming event around 56 million years ago – known formally as the Paleocene-Eocene Thermal Maximum (or PETM) – isn’t easy.
To do so, we developed a computer model simulating plant evolution, dispersal, and carbon cycling. We compared model outputs to fossil pollen and plant trait data from three sites to reconstruct vegetation changes such as height, leaf mass, and deciduousness across the warming event.
The three sites include: the Bighorn Basin in the United States, the North Sea and the Arctic Circle.
We focused our research on fossil pollen due to many unique properties.
First, pollen is produced in copious amounts. Second, it travels extensively via air and water currents. Third, it possesses a resilient structure that withstands decay, allowing for its excellent preservation in ancient geological formations.

A shift in vegetation
In the mid-latitude sites, including the Bighorn Basin – a deep and wide valley amidst the northern Rocky Mountains – evidence indicates vegetation had a reduced ability to regulate the climate.
Pollen data shows a shift to smaller plants such as palms and ferns. Leaf mass per area (a measure of leaf density and thickness) also increased as deciduous trees declined. Fossil soils indicate reduced soil organic carbon levels.
The data suggest smaller, drought-resistant plants including palms thrived in the landscape because they could keep pace with warming. They were, however, associated with a reduced capacity to store carbon in biomass and soils.
In contrast, the high-latitude Arctic site showed increased vegetation height and biomass following warming. The pollen data show replacement of conifer forests by broad-leaved swamp taxa and the persistence of some subtropical plants such as palms.
The model and data indicate high-latitude regions could adapt and even increase productivity (that is, capture and store carbon dioxide) under the warmer climate.
A glimpse into the future
The vegetation disruption during the PETM may have reduced terrestrial carbon sequestration for 70,000-100,000 years due to the reduced ability of vegetation and soils to capture and store carbon.
Our research suggests vegetation that is more able to regulate the climate took a long time to regrow, and this contributed to the length of the warming event.
Global warming of more than 4°C exceeded mid-latitude vegetation’s ability to adapt during the PETM. Human-made warming is occurring ten times faster, further limiting the time for adaptation.
What happened on Earth 56 million years ago highlights the need to understand biological systems’ capacity to keep pace with rapid climate changes and maintain efficient carbon sequestration.

Abstract
The Paleocene–Eocene Thermal Maximum (PETM) around 56 million years ago was a 5–6°C global warming event that lasted for approximately 200 kyr. A warming-induced loss and a 70–100 kyr lagged recovery of biospheric carbon stocks was suggested to have contributed to the long duration of the climate perturbation. Here, we use a trait-based, eco-evolutionary vegetation model to test whether the PETM warming exceeded the adaptation capacity of vegetation systems, impacting the efficiency of terrestrial organic carbon sequestration and silicate weathering. Combined model simulations and vegetation reconstructions using PETM palynofloras suggest that warming-induced migration and evolutionary adaptation of vegetation were insufficient to prevent a widespread loss of productivity. We conclude that global warming of the magnitude as during the PETM could exceed the response capacity of vegetation systems and cause a long-lasting decline in the efficiency of vegetation-mediated climate regulation mechanisms.

Events like the PETM expose the fragility of the systems that sustain life and demonstrate how easily they can be tipped into new and often hostile states. Far from being the work of an infallible designer fine-tuning a planet for a single favoured species, Earth’s history shows a world continually shaped by feedback loops, chance events and the slow, directionless process of evolution. When those systems are pushed too far or too fast, life suffers — and it takes tens of thousands of years for the planet to recover.
What makes the comparison with today so stark is the rate at which we are forcing change. The PETM was a natural carbon-cycle disturbance that unfolded over millennia. Our own contribution has taken place in a geological instant, yet it is already driving shifts comparable in magnitude to that ancient warming pulse. If slow change overwhelmed ecosystems then, the acceleration humanity has produced is even more concerning.
Understanding the PETM is not simply an academic exercise. It is a reminder, written in deep time, that there are limits to what living systems can endure and that “business as usual” can push Earth into states incompatible with the world we inherited. The past cannot tell us exactly what will happen next, but it does show that the consequences of inaction are neither abstract nor remote. The warning signs are etched in the rocks; whether we heed them is up to us.
One thing we know is that there is no watching sky daddy who's going to come and rescue us from our folly.

The story of our origins is written in the ground of Africa. It is real, tangible, and objective — a record that doesn’t rely on belief or interpretation, but on physical evidence left behind by our ancient ancestors. A fresh chapter of that record has just been described in a new open-access paper in Nature Communications, authored by an international team of palaeoanthropologists led by Professor David R. Braun of the Center for the Advanced Study of Human Paleobiology at George Washington University, and the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany.
By comparison, the origins narrative found in Genesis reflects the worldview and assumptions of people who believed the Earth was small, flat, and covered by a solid dome. It is astonishing that, even today, some treat that ancient cosmology as a more reliable account of human history than the rich and expanding fossil and archaeological record in Africa. Yet such individuals continue to seek influence over policy, law, morality, and social institutions, grounding their authority not in evidence, but in pre-scientific tradition — a worldview formed long before the wheel, let alone modern science.
In Ice Age Europe, when modern humans were spreading across the continent and the last Neanderthals were fading from our story, something remarkable happened deep beneath the limestone hills of southern France. In the Chauvet-Pont-d’Arc Cave, in the Ardèche valley, a young human child walked through a dark passage and left her footprints in the soft clay floor.
Beside her walked a wolf.
That much we know. Frozen in time for over 30,000 years, those parallel tracks hint at a moment of curiosity, courage, and perhaps companionship long before the first domesticated dogs trotted at our heels. They offer a tantalising glimpse into a forgotten world — the world that inspired my new novel.
The Girl and the Wolf is a story that imagines how such a bond might have begun. It follows Almora, an inquisitive, strong-willed child of the Drognai clan, raised alongside a rescued wolf cub named Sharma. As Almora grows into a capable young woman, her life takes an extraordinary turn when she meets Tanu — one of the last Neanderthals in Europe. Their unlikely love, and Tanu’s struggle to be accepted by Almora’s people, explores themes of kinship, belonging, and the courage to overcome fear of the Other.
Researchers at Woods Hole Oceanographic Institution have shown, in a paper just published in PLOS ONE, that the rise of Sumerian civilization in Mesopotamia was strongly influenced by the dynamic interplay of tides, rivers, and sedimentation at the head of the Arabian Gulf. In doing so, they remind us just how parochial and derivative the culture that produced the origin myths in Genesis really was.
According to Genesis — which places the Middle East, and the Hebrews in particular, at the centre of everything — humans were created fully formed, without ancestry, in a ready-made Bronze Age civilisation.
Within just five generations of a supposed genocidal global flood that allegedly reset life on Earth, eight survivors are said to have produced a population large and skilled enough to embark on a massive civil engineering project: building a tower up to Heaven. In this worldview, Heaven lay just above the clouds over the Middle East, on a flat Earth watched over by a creator god who could apparently be taken by surprise.
Meanwhile, several other ancient civilisations were continuing uninterrupted, apparently unknown to the author of Genesis — despite the fact that some of the stories in Genesis are clearly derived from older Mesopotamian and Egyptian myths. Both the genocidal flood myth and the Tower of Babel narrative draw directly on Mesopotamian sources: the flood from the Epic of Gilgamesh, and the tower itself from the Great Ziggurat at Ur.
What the Genesis myths fail to acknowledge is the fundamental role of geological and environmental change in shaping human civilisation. The authors of these myths believed they lived in an unchanging world, created especially for them by a perfect god. There is no hint of plate tectonics shifting continents, no awareness that volcanic gases can alter climates, or that major rivers can change course or silt up. Yet such processes could and did disrupt the regular flooding on which early agriculture depended. Silting and delta formation could leave once-coastal communities stranded inland, while blocking the twice-daily tidal ebb and flow that once reached deep upriver.
This paper in American Journal of Archaeology is tentative support for a theory that I find fascinating because it offers an explanation for the implausible Exodus myth in the Bible. The theory is that the myth is an exaggerated retelling of the expulsion or voluntary exile, of the Ahtenist sect from Egypt, complete with a 'royal' leader in the form of 'Moses' (an Egyptian name) - a retelling that grew over time and incorporated multiple miracles and the origins of the 'Law', with each telling until a small band became a mass exodus from which an entire new nation was built.
The exodus of Hebrew slaves from Egypt has too many inconsistencies for it to be real history - for example, the claim is that "600,000 men on foot" (Exodus 12:37), complete with their women, children and livestock, fled from Egypt into Sinai. That would mean some 2-3 million people - more than the then entire population of Egypt, plus livestock - far more than could be supplied with food and water in Sinai. There is also no archaeological evidence of such a large population ever living in Sinai for 40 years. It is inconceivable that they would leave no trace, not even the graves of those who died.
Then there is the story of 600, (horsedrawn) chariots (Exodus 14:7) pursuing them into the Red Sea, right after all the livestock, including, explicitly, all the horses, were killed in one of the plagues (Exodus 9:3-6).
Then there is the small geo-political problem that the story of crossing the Red Sea into Sinai 'from Egypt; ignores the fact that at that time Egypt not only controlled Sinai but its political and military control extended into Canaan, so the Israelites were leaving Egypt into... Egypt.
It is probably significant that during the entire telling of the tale of the Israelite's supposed captivity in Egypt, the pharaoh is invariably named 'Pharoh' (A Hebrew word), but never by his real name - Imhotep II, Rameses, Akhenaten, etc. It's as though the story-teller didn't know their names. This would be the equivalent of telling the Medieval history of England and only ever referring to 'King', never John, Henry IV, Edward II, etc.
A phrase much loved by journalists (and creationists) is “the history/science books will need to be re-written”. It’s a convenient bit of lazy journalistic rhetoric — but in this case, the book that actually needs to be re-written is the Bible.
The discovery in question concerns the migration of early Homo sapiens, who may have spread from the Levant across Asia Minor (modern-day Türkiye) and then into Greece via a northern Aegean land bridge, exposed when sea levels were much lower during the last Ice Age — between 115,000 and 11,700 years ago.
This new evidence challenges some existing models of early human migration routes. However, it represents only a refinement of the broader, well-established story of humanity’s dispersal out of Africa, not a challenge to it. What it does completely undermine, however, is the Biblical narrative claiming that all humans descended from a single, ahistorical couple created without ancestors some 6,000 to 10,000 years ago — followed by a supposed global “reset” just 4,000 years ago when a genocidal flood left only eight related survivors.
The evidence for this Ice Age land bridge comes from the recovery of 138 stone tools at ten sites within a 200 km² area around Ayvalık in north-west Türkiye, opposite the Greek island of Lesbos.
Thousands of years before creationism’s god supposedly decided to create a small, flat planet with a dome over it, centred on a tiny patch of the Middle East, humans were already leaving road signs and directions to water sources carved into rocks in what is now the Arabian desert. These carvings offer a fascinating insight into the region’s prehistoric megafauna—and, of course, all such evidence of early human activity would have been completely obliterated by the biblical genocidal flood, had such an event really occurred as described.
The rock carvings were discovered by an international team of archaeologists, led by the Heritage Commission of the Saudi Ministry of Culture, and including scholars from the Max Planck Institute of Geoanthropology, King Abdullah University of Science and Technology (KAUST), University College London, Griffith University’s Australian Research Centre for Human Evolution (ARCHE), and others. Their findings were published open access in Nature Communications a few days ago.
At the time, the region that is now arid desert was made habitable by a humid period following the Last Glacial Maximum (LGM), when surface water was abundant. Stone tool manufacture from the site shows clear cultural links with Neolithic societies in the Levant—ironically, the very region where the authors of Genesis set most of their imaginative origin myths, apparently oblivious to the deeper history of the area or the existence of earlier human populations beyond their narrow horizons.
A recent archaeological finding, by Beniamino Mecozzi of Sapienza University of Rome, Italy and colleagues, at the site of Casal Lumbroso in northwest Rome, has once again refuted the Bible narrative by extending the known depth of human prehistory far beyond the limits imposed by biblical literalism.
In sediments dated to some 400,000 years before creationism’s mythical 'Creation Week', the research team has uncovered evidence that early humans were butchering elephants with small stone tools and then fashioning large implements from the animals’ bones. These traces of planning, adaptation, and technological innovation demonstrate that human ingenuity was already well advanced hundreds of millennia before the supposed creation of Adam.
More interestingly from a scientific perspective is not the incidental refutation of ancient creation myths, which happens with almost every archaeological and palaeontological discovery, but the fact that these hominins predate the successful Homo sapiens migration out of African and into Eurasia by tens of thousands of years and pre-date even the earliest evidence of Neanderthals in western Eurasia.
Such discoveries highlight the sheer scale of time over which our lineage evolved—an evolutionary saga measured not in millennia but in hundreds of thousands of years. The people who left these marks were not modern humans, but archaic members of the genus Homo, close relatives or ancestors of the Neanderthals. Their world was already ancient when the earliest chapters of Genesis were imagined.
The bad news for creationists continues unabated - because science continues unabated to reveal the truth.
Creationists like to insist that the Bible’s tales of creation and Noah’s flood are real history, not myth. But once again, science has delivered a devastating blow to that fantasy. A new open access paper in Nature Communications reports the DNA of 58 individuals from the Baligang archaeological site in central China, spanning from the Middle Neolithic to the Late Bronze Age (6,500 BP - 2,500 BP). Far from supporting the idea of a world repopulated just a few thousand years ago by Noah’s family, the evidence shows continuous human settlement, migration, and cultural development stretching back thousands of years before, during and after the supposed date of the Biblical flood - about 4,000 years BP.
The genetics reveal a population that was anything but “reset.” Northern and southern East Asian groups repeatedly mixed at Baligang, leaving detectable signatures of long-term population movement and exchange. Around 4,200 years ago, southern ancestry became especially prominent, signalling migration into the region. Burial evidence adds further depth: the males were closely related along the paternal line, while the females carried diverse maternal lineages—clear evidence of patrilineal clans drawing in women from outside communities. This is a picture of a complex, interconnected society developing steadily over time.
The creationism cult took another blow yesterday with the publication of details of the oldest jewellery workshop yet found in Western Europe—dating to at least 32,000 years before the mythical six-day creation of everything from nothing. The site appears to have been used for the organised manufacture of shell ornaments, suggesting a society in which the production and trade of personal adornment already played an important role.
The discovery, made by a team of scientists from the Centre national de la recherche scientifique (CNRS), Université de Bordeaux, the ministère de la Culture, and Université Toulouse-Jean Jaurès, is published in the Proceedings of the National Academy of Sciences (PNAS). It records the excavation of a Palaeolithic site in southwest France, dating from a period when Homo sapiens were spreading into the region and Neanderthals were in decline.
However, the evidence points to a more complex story — one of coexistence and cultural exchange, or even the absorption of Neanderthals into the expanding H. sapiens populations, with traditions and technologies merging. It also raises the possibility that H. sapiens had been established in the area far earlier, perhaps through an earlier migration wave.
Examples of Early and Middle Holocene human burials from southern China. This figure shows six human burials from Huiyaotian (A: M14, B: M19, C: M20) in Nanning and Liyupo (D: M23, E: M24, F: M28) in Long’an, both shell-midden sites located in the Guangxi Zhuang Autonomous Region. All individuals are in flexed positions, with several exhibiting hyper-flexed postures (A and E: male, B–D and F: female).
They say that when you dig deep enough, the earth always tells a story—one that often clashes with stories written by humans. A recent archaeological discovery in southern China and Southeast Asia is one of those earth’s stories, and it’s a loud one. Scientists have found human remains, deliberately smoke-dried and ritually treated, dating back between 12,000 and 4,000 years ago. These mummified remains, buried in tight, crouched postures, were mummified by being exposed near low-oxygen smoky fires — not cremated, but preserved by ritual smoke-drying techniques.
A point I've made several times in these blog posts, but one which is worth repeating, is that any archaeology which predates the supposed date of the Biblical genocidal flood is irrefutable evidence that no such flood ever happened, because it simply wouldn’t be there—or at best would be buried under a thick, global layer of silt. Similarly, any archaeological evidence that predates the supposed 6-day creation of the universe is irrefutable evidence that no such creation event happened according to the Bible’s timeline.
Lastly, anything which refutes the Bible’s timeline, or contradicts the occurrence of events described in it, is irrefutable evidence that the Bible could not have been written by the omniscient, omnipotent creator god it claims to describe.
So, this recent discovery, reported by a team of archaeologists from Australian, Chinese, and Japanese universities, in reported open access in Proceedings of the National Academy of Sciences of the USA (PNAS) is about as conclusive evidence as you could wish for that the Bible was not written by the god described in it. Any claim that it is an inerrant textbook of science and history is undoubtedly false.

A team of researchers led by Dr. Mayukh Mondal of the Centre for Genomics, Evolution & Medicine, Institute of Genomics, University of Tartu, Estonia, have used AI-powered demographic modelling to estimate the genetic ancestry of the people of Papua New Guinea (PNG), whose origins have long been debated.
Papua New Guineans have physical features that differ noticeably from many Asian populations, and some superficial similarities to sub-Saharan Africans have led to speculation that they might descend from a very early migration out of Africa, predating most other non-African Homo sapiens. This new study strongly challenges that hypothesis: it attributes PNG’s genetic distinctiveness instead to a substantial Denisovan admixture followed by a prolonged period of isolation, a severe population bottleneck, and slower population growth.
According to the creationist mythologies, all human beings alive today descend from Adam and Eve—or, in some versions, from Noah and his family after a global flood. If that were literally true, then all living humans would share a very narrow genetic base: mitochondrial DNA (passed via the maternal line) would be limited to a very small number of variants, and all males would share essentially the same Y-chromosome (barring mutation) tracing back to the same male ancestor.
However, the observable facts are that human genetic diversity is much richer than those narratives predict. The mitochondrial DNA lineages in living people trace back to multiple distinct haplogroups with divergence times of tens to hundreds of thousands of years within Africa and beyond into archaic ancestors; similarly, Y-chromosome diversity indicates many lineages. Our human genome tells a far more complex story: long periods of evolution in isolation, multiple migrations, re-mixing, and interbreeding with related hominin species.
The same applies to other species which creationists mythology insists are the descendants of a small number of survivors of the same genocidal flood. Few living species show evidence of such a narrow genetic bottleneck, which would probably have resulted in far too much inbreeding resulting in extinction for most of them.
All non-African humans today are descended from the major “Out-of-Africa” (OOA) migration(s) of Homo sapiens. As populations moved into Eurasia, they interbred first with Neanderthals, then with Denisovans. Underlying all this, there is also the possibility of genetic contributions from even earlier human migrations (e.g. H. erectus) into the ancestors of Neanderthals, Denisovans, or earlier modern humans. Given the evidence that hominin populations often interbred when they came into contact, it would be surprising if there were no admixture between H. erectus (or similar early lineages) and the predecessors of Neanderthals and Denisovans (often thought to include H. heidelbergensis or H. antecessor).
Archaeologists led by Budianto Hakim of Indonesia’s National Research and Innovation Agency (BRIN) and Professor Adam Brumm from Griffith University’s Australian Research Centre for Human Evolution have uncovered evidence of tool-making on the Indonesian island of Sulawesi dating back 1.04 million years. The identity of the toolmakers remains unknown, as no hominin fossils have yet been found on the island. Their discovery has just been published open-access in Nature.
The most likely candidates are Homo erectus or a descendant population that adapted to Sulawesi’s distinctive environment. The island lies close to Flores, home of the diminutive ‘Hobbit’ (H. floresiensis), thought to have evolved from H. erectus through island dwarfism, a process that also produced the miniature elephants of Flores. A related discovery was made in 2019 on Luzon in the Philippines, where H. luzonensis—another likely offshoot of H. erectus—was identified. It is therefore entirely plausible that H. erectus, or one of its evolutionary branches, was present and making tools on Sulawesi more than a million years ago.
For creationists, such finds are troublesome because they align seamlessly with evolutionary theory, showing hominins branching, adapting, and diversifying in different environments, just as Darwin and Wallace first described in 1859. They also highlight the profound role of environment in shaping evolutionary outcomes.
For science, the discovery is particularly significant because it implies that an early hominin was capable of undertaking sea crossings across the formidable ‘Wallace Line’—a biogeographic boundary that long isolated the fauna of Australasia from mainland Asia by preventing the natural dispersal of terrestrial animals.
