Tiny fossils found in 1.7 billion-year-old mud yield clues to the evolution of complex life

For young-Earth creationists, some of the most troublesome evidence comes in the smallest packages. Microscopic fossils preserved in ancient Australian mudstones record organisms living approximately 1.75–1.4 billion years ago — an antiquity impossible to reconcile with the few thousand years allowed by a literal reading of the biblical genealogies. These organisms were already part of aLayers of 1.7 billion-year-old sedimentary rocks, Kakadu National Park, Northern Territoryn evolving biosphere more than a billion years before the supposed “Creation Week”. Their existence presents a chronological problem that no amount of argument about the meaning of “kind” can resolve.

These fossils are the subject of a paper in Nature, by Maxwell A. Lechte and colleagues, investigating the environments inhabited by some of the earliest known eukaryotes. Eukaryotes are organisms with structurally complex cells, typically containing a nucleus and specialised internal compartments; they include animals, plants, fungi and numerous microscopic organisms. Here, “complex life” refers to cellular organisation, not to miniature animals swimming through those ancient seas. Understanding these early cells helps explain the evolutionary foundations upon which much later forms of life depended.

Glossary.

Aerobes

Organisms that use oxygen in their metabolism. Obligate aerobes require it; facultative anaerobes can grow with or without it; microaerophiles require oxygen at concentrations below those in ordinary air.

Benthic

Living on, in or close to the bottom of a sea or lake. A “benthic habit” means a bottom-dwelling way of life.

Planktonic

Living suspended in the water and drifting largely with currents, rather than inhabiting the seabed.

Bottom waters

The water immediately above the seabed. It can lack oxygen even when the surface waters contain it.

Morphological complexity

Complexity of physical form or structure. Elaborate fossil walls, ornamentation and extensions can help researchers recognise probable eukaryotes.

Palaeontological, sedimentological and geochemical analyses

Studies of fossils, sediments and their formation, and the chemical composition of geological materials, respectively. Combining them helps reconstruct both ancient organisms and their environments.

Body fossils and molecular biomarkers

Body fossils preserve remains or impressions of organisms. Molecular biomarkers are chemical traces of biological molecules that can provide evidence of ancient life even without recognisable bodies.

Proterozoic eon

The interval from approximately 2.5 billion to 539 million years ago, encompassing much of the early history of eukaryotic life.

Neoproterozoic era

The final part of the Proterozoic, approximately 1 billion to 539 million years ago. The researchers propose that eukaryotes expanded substantially into planktonic habitats during this interval.

The research also illustrates something creationist caricatures of science routinely overlook: scientists continually test their explanations against evidence. Discoveries of living eukaryotes capable of surviving without oxygen, together with evidence that ancient seas were widely oxygen-poor, had raised questions about whether the earliest eukaryotes needed oxygen at all. To investigate, the researchers turned to rock cores drilled decades ago during mineral exploration and subsequently stored in Darwin. They examined more than 12,000 microfossils and analysed the sediments and their chemistry to reconstruct the organisms’ habitats. Old collections, approached with new questions, can still yield major discoveries.

The resulting pattern was revealing. Eukaryotic fossils occurred almost exclusively in sediments deposited beneath oxygenated waters, whereas sediments from oxygen-free settings still preserved other microbial fossils. Their distribution suggests that these early eukaryotes used oxygen and probably lived on the seabed. The researchers also propose that a much later expansion into planktonic habitats helped shape subsequent diversification. This connects evolutionary history with the availability of suitable environments: the opportunities for complex organisms to flourish depended on the physical and chemical conditions around them.

This does not establish every step in the origin of the eukaryotic cell, nor demonstrate that one particular rise in oxygen directly caused its appearance. It does strengthen the evidence that oxygen availability constrained early eukaryotic habitats. The broader picture is one of evolution unfolding within a changing planet, with environmental conditions opening opportunities and imposing limits. There is no requirement here for foresight or a predetermined destination.

Creationists may welcome any suggestion that scientists are reassessing an earlier interpretation, but the revision offers them no chronological refuge. Whether these organisms inhabited the seabed or drifted in the water, and precisely how they used oxygen, are questions within an ancient evolutionary history. Reconsidering those details does not compress that history into a biblical timetable. Science advances because its explanations remain answerable to evidence; a chronology fixed in advance can survive only by refusing the evidence that contradicts it.

Stored in an open-air warehouse in tropical Darwin, Australia, are dozens of trays containing cylindrical cores of rock. They are from drill holes bored hundreds of metres below the surface by mineral exploration companies decades ago.

Some of these cores at the Northern Territory Geological Survey are mudstone – a type of sedimentary rock formed from hardened seafloor mud. The companies that drilled these cores were largely unaware that within these mudstones were fossils of microscopic organisms buried on the seafloor of an ancient inland sea that covered much of northern Australia over 1.5 billion years ago.

As our new study, published today in Nature, shows, these fossils are crucial for addressing a longstanding puzzle about the major evolutionary leap that led to all complex life on Earth: the origin of eukaryotes.

Small but complex

All life on Earth can be placed into one of two types which are fundamentally different at the cellular level.

Prokaryotes (bacteria and archaea) have simple cellular organisation and are mostly single celled. Eukaryotes – including all animals, plants, algae and fungi – are very different. They have much more complicated cells featuring a nucleus and other specialised structures such as organelles which perform specific jobs.

The eukaryotic revolution transformed the planet. It led to the rise of animals and, eventually, to us. Based on observations from the genes of living organisms, it is now widely agreed that the last common ancestor of all living eukaryotes resulted from the symbiotic union of (at least) two prokaryotic microbes: an archaeon and a bacterium.

The first evidence for eukaryotic life comes in the form of these fossils of single-celled organisms. They show a level of cellular complexity not seen among prokaryotes, but common in eukaryotes.

Eukaryote fossils can be found around the world in rocks dating back at least 1.5 billion years. The fossils of the Northern Territory, the oldest of which date back to 1.75 billion years ago, are the oldest currently known eukaryote fossils globally.

But the ancient world in which early eukaryotes evolved remains shrouded in mystery. And so many fundamental aspects regarding their nature are unknown.

Oxygen – friend or foe?

Many types of bacteria can live and grow in places without oxygen. But nearly all eukaryotes alive today use oxygen for their survival. That’s because aerobic respiration – breaking down food using oxygen – provides the vast amounts of energy that complex life demands.

But the idea that oxygen has always been beneficial for all eukaryotes has come under fire in recent years. This follows the surprising discoveries of enigmatic eukaryotes that can thrive in conditions without oxygen.

There is also mounting evidence from the geological record that when eukaryotes were first evolving, oxygen was likely much scarcer. This means oxygen-free marine habitats would have been the norm. Collectively, these observations have called into question the assumption eukaryotes have depended on oxygen since their inception.

Genetic studies of living microbes belonging to groups considered closest to the ancestors of the first eukaryote can offer key insights into eukaryote ancestry. But only the fossil record can tell us about long-extinct lineages. And only geology can offer a window into the kind of world these organisms lived in.

More than 12,000 fossils

For our new study, we crushed up samples of the mudstone cores stored in Darwin, then dissolved them. We identified more than 12,000 fossils by analysing the organic residue left behind by this dissolution under a microscope.

We also studied the mudstones the fossils were preserved in to better understand what the environment was like when the sediments were deposited. This offered insight about the habitats in which these eukaryotes lived. And by analysing the chemistry of these mudstones, we could determine whether oxygen was present in the ancient seawater.

Our results show that eukaryote fossils were found in environments ranging from coastal mudflats to the open sea. But they were present only in samples deposited in oxygenated settings. Samples from oxygen-free environments contained only simple, prokaryotic forms.

This suggests that even the oldest known eukaryotes that lived on Earth 1.7 to 1.4 billion years ago were dependent on oxygen. These data lend support to a long-held hypothesis that oxygen played a key role in driving the evolution of early eukaryotes.

Resolving the drivers and context of the major evolutionary leap represented by early eukaryotes is one of the major outstanding questions in the life sciences. Ongoing studies of these enigmatic, ancient microfossils will no doubt tell us more about our own origins – and our place in the cosmos.

Abstract
The evolution of the eukaryotic cell paved the way for the emergence of all complex life on Earth. Despite its significance, the environmental context of early eukaryote evolution is largely unknown^1,2. Here we use the geological record to reconstruct the habitats of the oldest known fossil eukaryotes, approximately 1.75–1.4 billion years old. Our integrated palaeontological, sedimentological and geochemical analyses show that although fossil eukaryotes are found in samples deposited in a range of environments from coastal to offshore, they are almost entirely restricted to those from settings with oxygenated bottom waters. This distribution suggests these organisms were aerobes (obligate, facultative and/or microaerophilic) and, given their size and morphological complexity, probably possessed mitochondria. Furthermore, their near absence from otherwise fossiliferous anoxic samples suggests a benthic habit, as planktonic eukaryotes would be expected to be present in both oxic and anoxic samples. We propose that eukaryotes were largely restricted to oxic benthic habitats for much of the Proterozoic eon, only expanding into planktonic habitats during the Neoproterozoic era (1–0.54 billion years ago). This late ecological expansion could account for the mismatch between the appearance of eukaryotic body fossils and molecular biomarkers³ and explain the stepwise increase in eukaryote diversity during the Neoproterozoic era⁴.

For young-Earth creationism, the fundamental problem remains the chronology. These microscopic organisms inhabited Earth more than a billion years before the supposed biblical creation. Debates about their metabolism or preferred habitat cannot make that immense span of time disappear. There is no evidence-based reconciliation between this geological history and a world only a few thousand years old; preserving the latter requires rejecting the former.

The study also illustrates how science progresses. Researchers revisit specimens, question assumptions and combine different kinds of evidence to distinguish between competing explanations. Whether early eukaryotes depended on oxygen is a question to investigate, not a doctrine to defend. Revising an interpretation in response to evidence strengthens our understanding; it does not render every alternative explanation equally credible.

What emerges is a history in which the evolution and distribution of complex life were constrained by environmental conditions. Oxygen availability helped determine where these early eukaryotes could flourish, while subsequent ecological expansion offered further opportunities for diversification. This does not mean that oxygen alone explains the origin of complex cells, but it places their history firmly within the workings of a changing natural world.

There is no need to imagine those ancient seas being prepared with humans in mind. Evolution has no foresight: organisms survive and reproduce under the conditions they encounter, and their descendants inherit the consequences. These tiny fossils preserve evidence of that long, contingent history — a history we can reconstruct by examining the rocks, rather than insisting that the rocks conform to an ancient creation story.

Creationism Refuted - How Life Could Have Started On Earth 4.33 Billion Years Before 'Creation Week'

AI-generated impression of the Hadean Bombardment

ChatGPT-6 Astra

New Study Pinpoints When Early Earth May Have Become Ready for Life’s Chemistry - Planetary Science Institute

For creationists who depend on gaps in scientific knowledge, research into the origin of life presents a recurring difficulty: scientists keep finding ways to investigate those gaps. One question is when the early Earth became sufficiently stable for the chemistry preceding life to persist. Producing potentially useful molecules would have achieved little if repeated impacts then destroyed them. Before life could gain a foothold, its chemical ingredients needed somewhere they could survive.

A new study by Oleg Abramov and colleagues, published in Nature Communications investigates that problem using a three-dimensional model of impact heating. The researchers identify approximately 4.33 billion years ago as a particularly favourable time for persistent prebiotic chemistry. That places the proposed opportunity billions of years before the entire universe supposedly appeared in the chronology of Young-Earth creationism.

The emerging picture scarcely resembles a world prepared as a comfortable home for living things. Early Earth endured bombardment by asteroids, comets and leftover planetary building blocks. As that bombardment declined, regions of the shallow crust could remain cool enough for fragile molecules to persist. Around 4.4 billion years ago, the simulations begin to show environments that escaped subsequent reheating above the study’s specified threshold.

There is an interesting complication: impacts could also help create opportunities for life’s chemistry. Water circulating through heated, fractured rock can produce hydrothermal environments with sources of chemical energy. The researchers therefore sought an overlap between enduring cooler regions and continuing hydrothermal activity. Their proposed favourable window represents a changing balance between destructive heating and potentially useful geological activity, with no foresight required.

The distinction between opportunity and occurrence matters. This study does not demonstrate that life began 4.33 billion years ago, nor establish that an “RNA world” actually existed then. It constrains the thermal conditions under which such a proposed stage could have persisted. The date also depends on assumptions about bombardment: a lower estimate of the incoming mass moves the favourable window earlier, towards 4.4 billion years ago.

For creationism, the difficulty extends beyond the enormous timescale. An unanswered question about life’s beginnings is being broken down into physical conditions that researchers can calculate, compare and challenge. Uncertainty remains, but uncertainty supplies questions for further investigation; it supplies no evidence for a supernatural designer. Here, another part of the origin-of-life problem becomes a tractable question about the history of a changing planet.

Creationism Refuted - 'Jumping Genes' Create New Functional Genetic Information - No Magic needed.

“Jumping genes” helped ants in their evolutionary triumph after the extinction of the dinosaurs

One of creationism’s favourite assertions is that evolution cannot produce “new genetic information” without an intelligent designer. What usually goes missing is a clear definition of information, an explanation of why known genetic mechanisms cannot generate novelty, or any evidence of the supposed designer doing anything. Meanwhile, evolutionary biologists continue to investigate the natural processes by which genomes change and organisms acquire new capabilities. A new study of ants provides another example of how productive that scientific approach can be.

As reported in Science Advances, an international team led by Dr Lukas Schrader has investigated the contribution of transposable elements, commonly called “jumping genes”, to ant evolution. These mobile DNA sequences can move or copy themselves within genomes. Their activity can be disruptive, but it can also supply material for evolutionary innovation. The research links their activity to the expansion of gene families, including those encoding the odour receptors so important to ants’ chemical communication.

The researchers compared genomes from 163 ant species, representing twelve of the sixteen living subfamilies. They identified independent bursts of transposable-element activity in the ancestors of major ant groups, preceding their rapid diversification following the Cretaceous–Palaeogene, or K–Pg, mass extinction approximately 66 million years ago. The findings support a connection between changes within genomes and the evolutionary opportunities created by a profoundly altered world.

The evolutionary significance is straightforward. A mass extinction changes the conditions under which survivors live: ecological relationships are disrupted, resources become available in different ways, and opportunities arise as ecosystems recover. A genetic variant that previously offered little advantage may become useful under these new conditions. Natural selection can then favour organisms carrying it. Neither the mutation nor the environmental upheaval needs to anticipate the outcome.

Nor does genetic novelty require a complete, finished gene to appear from nowhere. Duplication supplies additional copies of existing sequences, which can subsequently diverge; changes to the regulation and arrangement of DNA can also alter what an organism does. Calling the starting material “existing information” does nothing to prevent its descendants from acquiring new functions. The relevant questions concern what changed, how it changed, and what consequences followed—not whether creationists are willing to call the result “information”.

Here, the specific finding is an association between mobile DNA, expanding gene families and subsequent diversification. It should not be inflated into a claim that every extra receptor acquired a demonstrated new function, or that the asteroid impact directly produced particular beneficial mutations. Nevertheless, the study supplies evidence for a natural route connecting genomic change with evolutionary diversification, precisely where the creationist argument substitutes an assertion of impossibility.

For young-Earth creationists, there is the additional inconvenience of the timescale. This diversification followed an extinction event some 66 million years ago—thousands of times further into the past than their entire supposed history of the Universe allows. Ant evolution was already unfolding in a world unimaginably ancient by biblical standards. What emerges is a history of genetic change, environmental catastrophe and opportunities exploited by surviving lineages, without foresight or a predetermined destination.

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

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

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

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

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

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

AI-generated impression of a Yellowstone supereruption

Yellowstone hot spring.

End of humanity? Blow-by-blow account of what would happen if the Yellowstone supervolcano erupted now

One of the more curious creationist claims is that Earth was perfectly designed for human life by an all-powerful, all-knowing and omnibenevolent creator. This comforting picture tends to concentrate on pleasant scenery, sunshine and things we can eat, while overlooking the planet’s considerable capacity to kill us. Yellowstone provides a particularly impressive example of what must be left out of the picture. It tends to be made by those fortunate individuals born to the relative comfort and security of a technologically-advanced society and it of course attributed to the locally-popular god.
Beneath the spectacular landscape of Yellowstone National Park lies a volcanic system whose history includes enormous explosive eruptions. Its most recent caldera-forming eruption occurred approximately 631,000 years ago — long before the supposed ‘Creation Week’ of young-Earth creationism. A comparable event today could devastate surrounding regions, spread ash across large areas of North America and disrupt the global climate, with serious consequences for agriculture. That is an extraordinary feature to include in a world supposedly engineered for our benefit.

None of this means Yellowstone is ‘overdue’ for a supereruption, or that such an event would wipe out humanity. As the US Geological Survey explains, volcanoes do not follow a timetable, and another catastrophic eruption at Yellowstone is by no means inevitable. Scientific accuracy matters here: the argument against benevolent design needs no assistance from exaggerated claims of impending doom. The existence and geological record of these hazards are quite sufficient.

The underlying problem for creationism is the difference between a planet on which humans can live and one perfectly arranged for human welfare. Our existence establishes the former; it does not demonstrate the latter. Evolution provides a straightforward reason why organisms possess adaptations to the environments in which their ancestors survived. It gives us no reason to expect those environments to remain safe, or the physical processes shaping them to take account of our needs.

An omnipotent designer, however, cannot be excused as an engineer forced to work within constraints beyond its control. If the planet’s life-supporting features are to be credited to deliberate benevolence, its destructive features also require an explanation. Pointing to the beauty of Yellowstone while overlooking the processes capable of devastating its surroundings is selective accounting. Invoking a mysterious divine purpose merely assumes the benevolence that the design argument was supposed to establish.

The creationist difficulty remains even without the worst-case details: a habitable Earth is not a promise of a hospitable Earth. Our protection from its hazards depends on understanding natural processes and acting on the evidence — a rather more useful response than assuming that everything was arranged with our welfare in mind.

Study of bone strength reveals new clues about human evolution | EurekAlert!

One of the persistent problems for creationism is that our ancestors left evidence of their existence millions of years before the supposed biblical “Creation Week”. Worse still for the claim that humans were created separately from the other apes, those ancestors possessed combinations of characteristics that make sense as stages in an evolutionary history. The creationist insistence that a fossil must be either “just an ape” or “fully human” cannot accommodate the very mixtures of ancestral and derived features that evolution predicts.

A new study published in Science Advances adds another piece to this picture. Led by Kristian J. Carlson of the Keck School of Medicine of the University of Southern California, the researchers examined CT scans of limb bones from seven fossil hominins, dating from approximately 3.7 million to 1.5 million years ago. By analysing the structure of their bone shafts, they estimated resistance to bending and twisting and compared strength across the limbs.
Bone responds to the mechanical loads placed upon it during life, so its internal structure offers clues to habitual activity. In the sampled Australopithecus individuals, relatively strong upper arms suggest substantial climbing, while the relationship between thigh-bone and shin-bone strength was more human-like. Early Homo, by contrast, showed relatively stronger thighs compared with upper arms, consistent with greater reliance on terrestrial walking. These findings support a change in locomotor behaviour, although seven individuals cannot establish every step or the precise pace of that transition.

The evolutionary significance lies in the combination. Upright walking could coexist with continued use of the trees: acquiring one capability did not require the immediate abandonment of another. An ancestor with this mixture was a functioning animal in its own environment, with no need to anticipate the anatomy or lifestyle of its distant descendants. Evolution has no destination, and modern humans were never a goal towards which these populations were consciously or inevitably progressing.

For young-Earth creationism, the chronological difficulty is equally stark. Even the youngest fossils examined are about 150 times older than a generously extended 10,000-year biblical chronology. Their bone structure provides evidence about how these individuals lived; their geological ages place those lives in a past that the creationist narrative simply does not allow. Together, they present a much more substantial account of human origins than an assertion that fully formed humans appeared by supernatural decree a few thousand years ago.

Dogs 10,000 years ago roamed with bands of humans and came in all shapes and sizes

Last November, just as I was finalising the second of my Ice Age Tales novels, two papers appeared in Science examining a subject central to their underlying theme: the long relationship between humans and the wolves whose descendants became domestic dogs. My stories are set some 30,000–40,000 years ago and imagine the beginnings of that relationship. The new research examines later chapters, revealing that substantial diversity among dogs was already established thousands of years before the intensive breeding that produced modern pedigree breeds.

The distinction matters. These papers do not show that domestication began only 11,000 years ago, nor that today’s breeds originated then. One identifies recognisably dog-like skull shapes in specimens dating to about that time, together with considerable variation among early Holocene dogs. The other traces how ancient dog populations moved and mixed alongside human communities over nearly 10,000 years. Both illuminate a prolonged history, rather than a single moment when wolves suddenly became dogs.

Earlier associations between wolves and hunter-gatherers remain possible, although neither paper establishes the particular scenario imagined in my novels. Taming an individual wolf is also different from domesticating a population: domestication involves inherited changes across generations, and behavioural changes need not coincide with readily identifiable changes in skull shape. The earliest stages of this relationship therefore remain difficult to reconstruct.

Dog domestication is, of course, a classic example of evolution under human influence. Its history presents several awkward questions for creationism, especially claims that substantial biological change is impossible and that the natural world fits a chronology of only a few thousand years.

Australia’s ancient rainfall patterns more complex than previously believed – News

For creationists who attribute much of Earth’s sedimentary record to a single, year-long global flood, the difficulty goes well beyond explaining how so much sediment accumulated. They also need to explain why natural archives preserve evidence of changing environments over periods vastly longer than their preferred age of the entire Universe. Producing layers of mud is one thing; reproducing a dated history of changing climate is quite another.

A new study by Alexander F. Wall and colleagues, published in Quaternary Science Reviews brings that problem into focus. The researchers analysed 69 natural palaeoenvironmental archives from tropical Australia, collectively spanning the past 130,000 years. Their purpose was to reassess how the complexity of rainfall patterns changed through the last glacial cycle.

Their conclusion challenges the suggestion that rainfall became uniquely variable and geographically patchy during the Holocene, the geological epoch encompassing approximately the past 11,700 years. Older records generally preserve less detail, so their apparent simplicity may reflect the limitations of the surviving evidence. A blurred photograph does not establish that the landscape it depicts contained fewer features.

The relevance to creationism is straightforward, although testing the biblical flood story was no part of the researchers’ purpose, but like almost all science, they did that incidentally, simply by revealing the facts. A flood can erode older deposits, transport fossils and produce successive sediment layers. None of those observations, however, demonstrates that it can reproduce the chronology and environmental history reconstructed from natural archives. A credible alternative would have to account for the ages, the sequence of environmental changes and the differences between locations together. Simply labelling everything “Flood sediment” supplies no such explanation.

A fossil feather preserved inside dinosaur poop could help explain why birds survived the mass extinction - Field Museum

Creationism’s problems with the fossil record now extend even to dinosaur droppings. A small piece of fossilised dung from Montana preserves evidence of a meal eaten some 66 million years ago — long before the supposed ‘Creation Week’ of young-Earth creationism. Within it are feathers that may help illuminate why some ancient birds disappeared while the ancestors of today’s birds survived. As, reported in Current Biology, researchers led by Field Museum palaeontologist Jingmai O’Connor, examining a coprolite — fossilised faeces — from the Hell Creek Formation found exceptionally preserved feathers alongside fish scales and bones belonging to a hesperornithiform, an extinct diving bird.

The feathers combine structures associated with waterproofing in modern aquatic birds with smaller, simpler, fuzzy body feathers. The researchers suggest that differences in insulation, feather replacement through moulting, or both might have influenced which bird lineages survived the cold conditions following the end-Cretaceous asteroid impact. Hesperornithiforms disappeared; the lineage containing all living birds survived. This remains a hypothesis, however: one coprolite cannot establish why entire groups became extinct. The distinction between the observed feathers and the proposed explanation is central to the Field Museum’s account of the findings.

For creationists, the difficulty goes beyond the date. This combination of ancestral and more derived features makes sense within an evolutionary family tree, in which different characteristics change at different rates. Evolution does not require every part of an animal to move together along some imaginary ladder from ‘primitive’ to ‘advanced’. Nor does an extinct bird need to be a direct ancestor of living species to preserve evidence of the evolutionary history they share. There is also a useful lesson here about adaptation. A feature that works adequately in one environment may become a liability when conditions change. Evolution has no foresight: natural selection cannot prepare organisms for an asteroid impact millions of years in the future. Survival depends on the circumstances organisms encounter and the characteristics they already possess, with chance also playing its part. What makes this discovery particularly telling is how an apparently unpromising object can yield evidence against which explanations can be tested. Scientists can investigate both the history of feathers and the unresolved details of extinction without invoking a designer. The uncertainty concerns which natural factors mattered most — and further fossils may help resolve it. Even a dinosaur’s discarded meal can contribute to that process.

On the one hand, they insist it was a sudden moment of creation in which multiple different body-plans were magically created without ancestry; on the other hand, they deny there was any history before 6,000-10,000 years ago. Clearly both views can't be right; However, both views can be wrong.

And for creationists of both camps, the Ediacaran presents and even bigger problem: not only did it precede the Cambrian, but it shows that complex body-plans had already evolved. This problem just got a lot more acute with the discovery of an exceptionally well-preserved fossil in a sheep field in Arctic Norway, in approximately 560 million year old rocks, of a fossils of Charnia, a branching, frond-like organism that lived during the Ediacaran Period, well before the Cambrian began. These organisms inhabited an ancient seabed hundreds of millions of years before the supposed ‘Creation Week’ of young-Earth creationism.

As a paper published in Palaeontology by researchers led by Dr Yorick Veenma reports, this is the first confirmed fossil of Charnia to be found in Scandinavia. It was found alongside other Ediacaran fossils and is a rare three-dimensional specimen which preserves anatomical details normally obscured in flattened impression.

Despite its superficial resemblance to a fern, Charnia was no plant. It belonged to the rangeomorphs, an extinct group generally interpreted as early animals, although their precise relationships to living animal groups remain debated. We need not claim that Charnia was a direct ancestor of any particular Cambrian animal to appreciate its significance: large organisms with elaborate body structures already existed before the diversification that creationists so often misrepresent as an instantaneous act of creation.

How We Know the Bible is Wrong - It Is Written In The Stars

Creationists and fundamentalist Bible literalists continue to insist that the Bible is the inerrant word of their god and a more reliable account of science and history than anything discovered through scientific investigation. Yet however emphatically that claim is repeated, repetition does not turn it into evidence.

The claim of divine authorship requires independent support. Quoting the Bible to establish the Bible’s authority merely takes us round in a circle. As Christopher Hitchens’s familiar principle reminds us, an assertion offered without evidence can be dismissed without evidence.

When I and other critics argue that biblical cosmology bears little resemblance to the observable universe, however, we can point to evidence. We can compare what the texts describe with what astronomical observations reveal, and ask whether those descriptions display the knowledge we would expect of an omniscient creator.

Consider the ancient cosmology reflected in Genesis: an earthly realm beneath a firmament that separates the waters above from the waters below, with the sun, moon and stars set in that firmament. The familiar illustration of a flat earth beneath a solid dome reconstructs this ancient worldview; Genesis does not describe a planet orbiting a star in a galaxy. Its heavenly lights serve to illuminate the earth and mark days, seasons and years. Genesis 1:6–19

Elsewhere, the imagery becomes even more striking. Revelation describes stars falling to earth following the announcement of a great earthquake, while Daniel’s vision depicts a horn casting down and trampling some of the heavenly host and stars. These are apocalyptic visions, with symbolic meanings, so it would be misleading to present them as straightforward astronomical claims. Nevertheless, anyone who insists on reading such passages as literal descriptions of physical events has an obvious problem: real stars are not little lights that can fall onto the ground and be trodden underfoot. Revelation 6:12–14; Daniel 8:9–10.

Now compare that ancient picture with the James Webb Space Telescope’s image below. It shows the “Treasure Chest”, a cloud of gas and dust enclosing a young star cluster in the Carina Nebula, some 7,500 light-years away. The cluster contains an estimated 70 stars and is thought to be around 1.3 million years old. This is just one small region within our own galaxy. Webb’s infrared measurements, translated into visible colours, reveal the physical structures of a stellar nursery. ESA/Webb image and description
