Analysis of a super-deep diamond reveals how water travels to the Earth’s interior

Creationists have long been fond of two superficially impressive but scientifically worthless arguments. The first is that tiny amounts of carbon-14 detected when diamonds are placed in an accelerator mass spectrometer somehow show that diamonds—and therefore Earth—are only a few thousand years old. The second is that the discovery of “water” deep inside Earth confirms the biblical “fountains of the great deep” and, when convenient, explains where all the water from Noah’s supposed global flood subsequently disappeared.

A paper recently published in Scientific Reports brings these two favourite misconceptions together in a combination that may prove irresistible to professional misrepresenters of science. It therefore seems prudent to explain what the researchers actually found before the inevitable claims begin circulating.

Carolina Camarda and colleagues examined an irregular diamond, just 3 millimetres long, recovered from the Juína region of Brazil. Super-deep diamonds form at depths greater than about 300 kilometres, rather than at the approximately 150-kilometre depths typical of most diamonds, and can preserve microscopic inclusions of minerals that record conditions far below the surface.

Using synchrotron X-ray tomography, diffraction and spectroscopy, the team mapped more than 100 inclusions inside the diamond. One completely sealed inclusion, only about 35 micrometres across, contained a complex mixture of goethite—an iron oxyhydroxide with the formula FeOOH—together with hematite and magnetite. Another inclusion contained ferropericlase, a mineral characteristic of the deep mantle, supporting the conclusion that the diamond originated far below the crust.

The researchers propose that the goethite originally formed within hydrated oceanic crust or lithosphere. As that crust was carried downwards at a subduction zone, the goethite changed into a high-pressure form capable of surviving within a relatively cold descending slab. At still greater pressures and temperatures it began to decompose into iron oxides, releasing H₂O and oxygen into the surrounding mantle. The diamond then encapsulated part of this mineral assemblage, preserving evidence of the process.

In other words, the discovery concerns the slow transport of surface-derived water downwards through plate subduction. It is not evidence of a primordial subterranean ocean bursting upwards to flood Earth. Nor does it show where the water from an imaginary global flood went afterwards. The “water” carried by goethite is chemically incorporated into its crystal structure, principally as hydroxyl groups; it is not a liquid ocean occupying enormous caverns beneath the crust. It can be liberated as molecular water only when the mineral undergoes chemical reactions under extreme mantle conditions.

The study examined one microscopic inclusion and made no estimate of a hidden ocean, no calculation of the volume of floodwater that could be accommodated, and no suggestion that surface water could disappear hundreds of kilometres into the mantle within a few months. What it describes is part of Earth’s deep-water cycle, driven by plate tectonics and operating over geological time. Indeed, the direction of transport in the authors’ model is exactly the reverse of the “fountains of the great deep”: hydrated rocks are carried from the ocean floor into the mantle, where some of their bound water is eventually released.

Nor did the researchers carbon-date the diamond. The paper contains no radiocarbon measurement at all. Carbon-14 has a half-life of about 5,730 years, making radiocarbon dating useful for formerly living material up to roughly 50,000–55,000 years old under ordinary conditions. It cannot determine whether a diamond formed hundreds of millions or billions of years ago, and mantle carbon does not necessarily begin with the atmospheric carbon-14 ratio required for conventional radiocarbon dating.

Most complete skeleton of 30 million-year-old dog discovered | University of Michigan News

My last blog post concerned a 210-million-year-old, gap-filling dinosaur from Zimbabwe that is helping palaeontologists to reconstruct the early evolution and dispersal of dinosaurs.

This post concerns another gap-filling fossil, although one from much closer to the present—just 30 million years ago. It is a remarkably complete skeleton of the early canid Mesocyon coryphaeus, one of the most complete pre-Ice Age canid skeletons yet found in North America.

This specimen fills a different sort of gap. Mesocyon coryphaeus, first named in 1879, is relatively common in the John Day Formation of Oregon, but it was previously known principally from skulls and teeth. Its postcranial skeleton—the bones behind the skull—had remained almost entirely unknown. The new specimen therefore fills an important anatomical gap in our understanding of how early canids moved, hunted and responded to the changing environments of Oligocene North America.

The fossil itself has had a curious history. It was collected during the late 1980s from land administered by the Bureau of Land Management near what is now the John Day Fossil Beds National Monument. Encased in a protective plaster jacket, it entered the monument’s collection after initially being mistaken for an oreodont—an extinct North American even-toed ungulate sometimes loosely described as resembling a mixture of sheep, camel and pig.

During the 1990s, the skull was separated from the surrounding rock for display, whereupon its teeth and cranial anatomy revealed that it was actually a canid. Park palaeontologists began exposing the remainder of the skeleton in 2012, but preparation continued intermittently for years. By the time the fossil was fully uncovered in 2022, more than 500 hours of painstaking preparation had been devoted to it.

University of Michigan palaeontologist Anne E. Kort, together with Jennifer Cavin of John Day Fossil Beds National Monument and Xiaoming Wang of the Natural History Museum of Los Angeles County, formally described the specimen in a paper published online in the Journal of Paleontology on 29 May 2026.

Known as JODA 3366, the specimen includes a complete cranium, an almost complete vertebral column in front of the sacrum, all the major limb bones and parts of both the forefeet and hindfeet. Only the tail and portions of the hands and feet are missing. It even preserves part of the baculum, or penis bone, establishing beyond reasonable doubt that the animal was male.

New Zimbabwean dinosaur species named by Museum scientist reveals Africa’s hidden history | Natural History Museum

It is gap-filling time again — not because palaeontologists have discovered some predetermined evolutionary “missing link”, but because another conspicuous blank on the palaeontological map is being filled. This time, the new evidence comes from Africa and concerns a dinosaur that lived about 210 million years ago, during the Late Triassic.

The discovery sheds new light on the early diversification and geographical distribution of dinosaurs, when they were still only a relatively minor component of terrestrial ecosystems. Over the following millions of years, they diversified into an extraordinary range of forms and became the dominant large land animals of the Jurassic and Cretaceous periods.

Gaps in the fossil record are, of course, eagerly seized upon by creationists desperate to find somewhere to insert their god. Their enthusiasm tends to diminish markedly whenever palaeontologists recover new evidence from one of those gaps. Each such discovery removes another supposed refuge for the ever-shrinking god of the gaps, so the evidence must be dismissed as misidentified, incorrectly dated or merely another example of “evolutionary storytelling”.

No matter how many gaps science fills, creationists continue to assure themselves that the next one will be different: that it will finally be the gap that science cannot investigate and into which their preferred creator can safely be inserted. Unfortunately for that strategy, palaeontologists continue to discover fossils, dating methods continue to improve, and previously neglected regions continue to be explored.

This latest discovery consists of a partial skeleton excavated from exposures of the Late Triassic Pebbly Arkose Formation on the shore of Lake Kariba in northern Zimbabwe. An international team of Zimbabwean, South African and British scientists has named the animal Musango matusadonaensis. The study was led by Professor Paul M. Barrett of the Natural History Museum, London, while the expeditions during which the fossils were collected were led by Professor Jonah Choiniere of the University of the Witwatersrand’s Evolutionary Studies Institute.

Musango was an early sauropodomorph — a member of the lineage that later produced the enormous, long-necked sauropods such as Diplodocus. Unlike those gigantic four-legged descendants, however, Musango was a relatively lightly built, predominantly bipedal animal. It measured an estimated 4.5 metres in length but weighed only about 222 kilograms. Its skull has not been recovered, so its diet cannot be established with certainty, although comparisons with related dinosaurs suggest that it was probably herbivorous or omnivorous.

The fossil record of early dinosaurs is extremely uneven. Europe, North America and parts of South America have been studied far more intensively than much of Africa, leaving large gaps caused not necessarily by the absence of dinosaurs but by the scarcity of sustained palaeontological exploration. Musango is only the fifth dinosaur formally named from Zimbabwe, following the description in 2024 of another sauropodomorph from the same formation, Musankwa sanyatiensis.

Phylogenetic analysis places Musango and Musankwa as close relatives within Unaysauridae, a group whose fossils are known from Africa, India and South America — landmasses that were then joined within Gondwana. Together, these discoveries support an emerging picture in which Late Triassic southern Africa contained several distinct ecosystems with their own dinosaur communities, rather than a single uniform fauna extending across the region. Africa was therefore not a peripheral spectator in early dinosaur evolution; its still-underexplored rocks may preserve crucial evidence about how dinosaurs diversified and spread before their later ecological dominance.

First absolute dating of Palaeolithic paintings in the Dordogne | CNRS

For the first time, scientists have obtained direct radiocarbon dates for Palaeolithic paintings in the Grotte de Font-de-Gaume in what is now southwestern France. A black-line drawing of a bison was created between 13,461 and 13,162 calibrated years before present (cal BP), while two parts of a mask-like figure produced dates ranging from about 16,000 to 14,200 cal BP. In other words, people were producing accomplished works of art in France more than 3,000 years before even the upper limit of 10,000 years that young-Earth creationists commonly allow for the entire age of Earth.

Not that this evidence is likely to persuade many creationists to reconsider their beliefs, of course. Once a preferred conclusion has been declared infallible, any evidence that contradicts it can simply be dismissed as fraudulent, mistaken or somehow “wrong”. One stock evasion is the evidence-free suggestion that radioactive decay rates must once have been different. In the case of radiocarbon dating, even known variations in atmospheric carbon-14 are measured and incorporated into the calibration curves. But no amount of calibration can correct a chronology that is wrong by design.

For anyone more interested in discovering the truth than in finding excuses to protect a preordained conclusion, however, these paintings are fascinating glimpses into how members of our species perceived the world around them, with its bison, horses, cave lions, mammoths and other Ice Age animals. Having visited the Grotte du Pech Merle in the Lot and the Lascaux II faithful reproduction of the famous Lascaux cave in the Dordogne, I can testify to the breathtaking magnificence of these monumental works.

Their purpose can only be surmised. They may have formed part of rituals intended to influence or appropriate the power of the animals; they may have recorded stories, conveyed knowledge or helped to instruct younger members of the group. None of these interpretations can yet be demonstrated conclusively. A controversial paper published in 1998 compared certain features of Upper Palaeolithic cave art with drawings made by a young autistic child with exceptional artistic ability. It did not, however, establish that any particular Palaeolithic artist was autistic.

During my visit to Pech Merle, our guide suggested that one of the great animal friezes might have been drawn in a matter of hours by a single artist, using bold, confident lines in black pigment. That interpretation may remain speculative, but the powers of observation, memory and control evident in those sweeping lines are unmistakable.

The new dating study was carried out on paintings in the Grotte de Font-de-Gaume, near Les Eyzies in the Dordogne, by an interdisciplinary research team led by CNRS researcher Ina Reiche. Direct radiocarbon dating had previously been considered impossible because the black pigments used at Font-de-Gaume, Lascaux and other decorated caves in the region were assumed to consist solely of iron and manganese oxides, which contain no carbon. However, the absence of carbon had never actually been demonstrated.

Using non-invasive Raman microspectrometry and hyperspectral imaging, the researchers examined black-line drawings of a bison and a figure interpreted as a human or animal face, or “mask”. These techniques revealed that charcoal was distributed uniformly throughout the black lines, rather than occurring only in isolated patches, helping to rule out contamination from graffiti or tourist activity.

Creationism Refuted - How Humans Modified Wild Rice - Because 'The Creator' Didn't Know What We Needed?

One grain to rule them all: the history of rice as a global food

A point made several times in these blog posts is that the creationist interpretation of Genesis presents the living world as having been deliberately created for human use. That raises an obvious question: why have humans needed to modify virtually every domesticated animal and cultivated plant to make it more useful?

In many cases, selective breeding has altered organisms so extensively that modern breeds and crop varieties are barely recognisable as descendants of their wild ancestors. Did the supposed creator fail to anticipate how humans would use them, or was it simply incapable of finishing the job and obliged to leave the improvements to us?

Creationists have never produced a satisfactory, evidence-based answer. Instead, they appeal to “mystery”, “unknowable intentions” or some other form of theological evasion — ways of avoiding the question while pretending to have answered it. Alternatively, they simply ignore the problem and continue asserting that Genesis provides an accurate account of history and the origins of living species.

Rice, of course, doesn't get a mention in the Bible, the cultural origins of whose authors were primarily the Tigris-Euphrates rivers of Mesopotamia and later the Nile in Egypt, where wheat and barley were the staple crops, so they knew nothing of the origins or cultivation of rice, nor of India or China for that matter. Wheat by contrast is mentioned in the Bible 51 times and barley, 37.

Science, by contrast, allows us to reconstruct increasingly detailed and testable histories of domesticated animals and cultivated plants. Genetics, archaeology and the study of ancient plant remains show how humans selected heritable variations and gradually changed wild populations through artificial selection, hybridisation and the movement of crops between regions. One particularly fascinating example is the origin and cultivation of Asian rice, Oryza sativa, which now provides sustenance for more than 3.5 billion people.

The evidence traces this history across a timescale wholly incompatible with the creationist belief in a 6,000–10,000-year-old Earth. Wild rice ancestral to modern cultivated rice was growing in the lower Yangtze region of China about 100,000 years ago. Humans began gathering and processing it approximately 24,000 years ago, and evidence of pre-domestication cultivation appears about 13,000 years ago. By around 11,000 years ago, plant remains show a rapid increase in characteristics associated with domestication, as generations of human selection transformed wild rice into a recognisably cultivated crop.

There is also evidence of rice cultivation in the Ganges valley of northern India as early as 6500 BCE—about 8,500 years ago. The details remain a subject of legitimate scientific debate, particularly whether Indian rice was domesticated independently and how much the eventual development of indica rice owed to hybridisation between local rice and japonica introduced from China. What is not in dispute is that modern rice emerged through a prolonged history of cultivation, selection, migration and hybridisation — not through an instantaneous act of creation.

The history of rice is the subject of an article in The Conversation by Garritt C. Van Dyk, Senior Lecturer in History at the University of Waikato, New Zealand. His article is reprinted below under a Creative Commons licence and reformatted for stylistic consistency:

How Evolution Works - The Founder Effect

Study: Hidden genetic diversity may have helped inbred brown tree snakes take over Guam - University at Buffalo

Biological invasions present evolutionary biologists with an apparent paradox. A newly established population may begin with only a handful of individuals and therefore contain only a small sample of the genetic variation present in its parent population. The resulting population bottleneck should increase inbreeding, reduce its capacity to adapt and expose harmful recessive mutations to natural selection. In extreme cases, the population should succumb to what population geneticists call an “extinction vortex”, in which declining genetic diversity and declining population size reinforce one another.

And yet some introduced species do precisely the opposite. They survive, proliferate and overwhelm the ecosystems into which they have been introduced. Few examples are more spectacular—or more ecologically destructive—than the brown tree snake, Boiga irregularis, on the Pacific island of Guam.

Native to Australia, Papua New Guinea and other parts of the western Pacific, brown tree snakes probably reached Guam as accidental stowaways in military cargo sometime after the Second World War. The invading population is believed to have been founded by only a handful of snakes. Nevertheless, their descendants multiplied until, in some parts of the island, densities reached an extraordinary 30,000 snakes per square mile.

The consequences for Guam’s wildlife have been catastrophic. As nocturnal, generalist predators encountering abundant prey that had evolved without such a snake, they devastated the island’s native birds, causing several species to disappear from the wild on Guam. They have also disrupted food webs, preyed upon reptiles and small mammals and caused hundreds of power cuts by climbing electricity infrastructure.

But how did a population founded by so few individuals avoid collapsing under the burden of inbreeding?

A new paper in Science Advances by Christopher A. Osborne of the University at Buffalo and colleagues from Buffalo and the US Geological Survey suggests that the answer lies partly in a form of genetic variation that earlier sequencing methods tended to miss.

The snakes did not, in fact, avoid the bottleneck. Their genomes retain compelling evidence of it. The researchers found that roughly half of each snake’s genome consisted of long “runs of homozygosity”—regions in which the copies inherited from the mother and father were almost identical. This is a genomic signature of intense inbreeding, comparable with that seen in some endangered species of conservation concern.

However, genetic diversity is not confined to changes in individual DNA letters. Using long-read sequencing, which can detect much larger differences, the researchers found nearly 19,000 structural variants. These included sections of DNA that had been duplicated, deleted, inserted or rearranged. Together, these structural variants affected almost eight times as much of the genome as the single-nucleotide variants upon which conventional estimates of genetic diversity have largely relied.

More importantly, the surviving variation was not distributed randomly. Structural variants were especially abundant around gene promoters and in genes associated with adaptive immunity and olfaction. Variation in immune genes could help the snakes respond to pathogens, while variation affecting their highly developed sense of smell could influence their ability to recognise prey, exploit different foods and distinguish closely related snakes from potential prey. In other words, a population can be genetically impoverished overall while retaining disproportionately important variation in precisely those parts of its genome that influence survival and adaptability.

A point I have made before in this blog is that the ignorance of the Bible’s authors is revealed as clearly by what they omitted as by what they included. When examined in the light of modern science, many of their claims turn out to be wrong, showing that they filled gaps in their knowledge with stories that reflected the prevailing superstitions of their culture. Meanwhile, the omissions reveal just how narrow their geographical and intellectual horizons were.

There is no unmistakable fact in the Bible that could not have been known, inferred or imagined by people living in the ancient Near East when its various books were written. There is no knowledge that required revelation from an omniscient being and no awareness of vast regions, peoples or periods of history lying beyond the experience of its human authors.

That is entirely understandable if the Bible is a collection of human writings. It is much more difficult to explain if its ultimate author was an omniscient god. Such an author would not have shared the cosmological limitations of ancient people or presented the world in the familiar ancient Near Eastern form found in Genesis: primordial waters divided by a firmament, dry land beneath it, and the Sun, Moon and stars placed in that firmament as lights. Whatever ingenious reinterpretations modern apologists may retrofit to the text, there is nothing in it that anticipates the real structure, age or scale of the Universe.

Nor is there any hint that people were already living on the other side of the planet. Archaeological evidence from Madjedbebe in northern Australia indicates human occupation by about 65,000 years ago. The Bible’s authors knew nothing of Australia, its First Peoples or the tens of thousands of years of human history that had already elapsed before the supposed events of Genesis.

What is perhaps more surprising is that educated adults today can still imagine that the Genesis creation myth is an accurate and inerrant account of history, despite its demonstrable errors and enormous omissions. The text contains no Australia, no Americas, no Pacific peoples and no conception of the deep human past—only the restricted world known to its authors, projected onto the entire planet.

Augustine of Hippo provides an illuminating example of how treating Scripture as historical fact could obstruct an otherwise rational consideration of the evidence. Contrary to a common misconception, Augustine did not insist that Earth was flat. By his time, its spherical shape had been understood by educated Greeks and Romans for centuries, and Augustine was prepared to concede that it might be demonstrated scientifically.

What he could not accept was that the far side of a spherical Earth might be inhabited, because that appeared irreconcilable with the biblical claim that every human descended from a single original man—and, after the supposed global flood, from Noah and his family. In De Civitate Dei, he wrote:

Australia’s most diverse marsupial predators have been hiding their origins for millions of years

To a palaeontologist, a gap in the fossil record is an unanswered question and an invitation to keep looking. To a creationist, it is more often treated as a convenient space in which to insert a supernatural explanation. The difficulty for creationism is that scientists have an inconvenient habit of finding the missing evidence, whereupon the gap becomes smaller, the evolutionary history becomes clearer, and creationists must quietly move their supernatural explanation somewhere else.

A particularly neat example is provided by a paper just published in Australian Zoologist by Timothy J. Churchill, Michael Archer, Suzanne J. Hand and Roy M. Farman. As Churchill explains in an article in The Conversation, a handful of tiny fossil jaws from north-western Queensland has supplied a previously missing opening chapter in the evolutionary history of Australia’s most diverse family of marsupial predators.

The family Dasyuridae contains almost 80 living species, including Tasmanian devils, quolls, dunnarts, planigales and antechinuses. They range from insect-eaters weighing only a few grams to the much larger Tasmanian devil, and occupy environments extending from the tropical rainforests of New Guinea to Australian deserts, grasslands and alpine woodland. Yet, despite this modern diversity, their early fossil history had remained frustratingly obscure.

Molecular studies indicated that dasyurids had diverged from their closest relatives millions of years before the earliest unambiguous fossils then known. Almost all accepted dasyurid fossils were younger than about five million years, leaving what palaeontologists call a “ghost lineage”: a branch whose existence was indicated by evolutionary relationships, but whose earlier fossil representatives had not yet been found. The animal once thought to fill that gap, Barinya wangala, was subsequently shown to belong to an entirely different family of peculiar, probably snail-eating marsupials called malleodectids.

Creationists sometimes present such gaps as evidence against evolution, apparently assuming that unless every organism that ever lived has obligingly become fossilised, been exposed at the surface and been discovered, the evolutionary history can be dismissed. But incompleteness is not inconsistency. Fossilisation is rare, suitable rocks are unevenly distributed, and tiny, fragile animals are especially unlikely to leave recognisable remains. Evolution nevertheless predicted that earlier dasyurids had existed. The question was whether any of them would eventually be found.

The new species, named Miyumba chrisdickmani, is known from six partial lower jaws recovered from Early Miocene deposits in the Riversleigh World Heritage Area on Waanyi Country. It lived about 23 million years ago and probably weighed only about 30 grams, making it comparable in size to a modern antechinus or large dunnart. It is now the oldest confirmed member of Dasyuridae, extending the family’s recognised fossil history by more than five million years.

Its significance, however, lies in much more than its age. The teeth of Miyumba possess a particular arrangement in which the third lower premolar is smaller than the first and second. This appears to be a shared derived characteristic, or synapomorphy, identifying dasyurids as a natural evolutionary group. At the same time, Miyumba retains several ancestral dental features expected in an animal close to the base of that group’s family tree.

That combination is precisely what evolutionary theory predicts: an early member of a lineage should possess the defining innovations inherited by its descendants while retaining features inherited from more distant ancestors. It should not look exactly like a modern Tasmanian devil, quoll or dunnart because those specialised forms had not yet evolved. Nor should it be unrelated to them. It should display a mosaic of ancestral and newly evolved characteristics — and that is exactly what Miyumba does.

How Snakes Lost Their Legs - 80 Million Years Before 'Creation Week'

Agustin Martinelli

80-million-year-old snake fossil sheds light on why lizards lost their limbs and started slithering

Of all the primitive ‘just-so’ stories in Genesis, the tale of how the serpent was condemned to crawl on its belly must rank among the most transparently mythological. Having supposedly tempted Eve to eat the forbidden fruit, God curses the serpent to go on its belly and ‘eat dust’ for the rest of its life. Although the story never explicitly says that the serpent previously had legs, the curse plainly implies a change and has traditionally been understood as an explanation for why snakes slither instead of walking.

Like so much of Genesis, it begins with an observation familiar to its authors—snakes have no legs—and invents a magical tale to explain it. It is an ancient example of an etiological myth: folklore devised to explain why something in the natural world appears as it does, long before anyone had the evidence or intellectual framework needed to understand its real history.

Even as mythology, however, the story is strangely incoherent. Genesis itself does not identify the serpent as Satan but introduces it as the most cunning of the wild animals God had made. Nevertheless, this supposedly ordinary animal can speak, reason and somehow knows about a prohibition that God had given to Adam before Eve had even been created. The text makes no attempt to explain how it acquired either this knowledge or the power of speech.

More awkward still for anyone insisting that the story is literally true, the serpent’s predictions prove substantially more accurate than God’s warning. God tells Adam that he will die on the day he eats the fruit. The serpent tells Eve that they will not die, that their eyes will be opened and that they will become like God, knowing good and evil. They eat the fruit, their eyes are opened and they do not die that day. God then confirms that the humans have indeed become ‘like one of us’ in knowing good and evil. According to Genesis itself, Adam goes on to live for another 930 years.

On the most straightforward reading of the story, therefore, the serpent tells Eve the truth while God’s threat to Adam proves false. Later theologians have attempted to rescue the tale by inventing a ‘spiritual death’, or by claiming that Adam merely began to die that day, but neither qualification appears in the text. These are apologetic repairs added by people who can see the problem but cannot admit that the story’s authors created it.

Science, meanwhile, has uncovered a very different account of how snakes acquired their extraordinary bodies—one involving neither talking reptiles nor fruit, curses or human disobedience, but descent with modification over immense periods of geological time. Snakes are highly modified members of the squamate reptile radiation. Their ancestors progressively elongated their bodies, increased the number of vertebrae and reduced their limbs as different lineages adapted to particular ways of life. Their evolutionary history extends back at least to the Middle Jurassic, about 160 million years ago.

Now, a paper published in Nature by an international team led by Tiago R. Simões describes an exceptionally well-preserved early snake from the Late Cretaceous of Brazil. Named Tametara mirim, the animal lived approximately 85–75 million years ago, when non-avian dinosaurs still dominated terrestrial ecosystems. It is the first articulated snake fossil known from Brazil and preserves a three-dimensional skull together with more than 100 connected vertebrae.

The preserved portion of its skeleton appears to have lacked forelimbs. Because the region around the pelvis is missing, the researchers cannot determine whether it retained vestigial hindlimbs, as some other early snakes did. Its skull also combines recognisably snake-like specialisations with ancestral features resembling those of other squamate reptiles—precisely the sort of mosaic of old and new characteristics expected in an evolving lineage, but not from the instantaneous transformation of an animal by a divine curse.

Storms that built a graveyard: ancient monsoons created a spectacular dinosaur fossil site

Young-Earth creationists are fond of pointing out that a single flood or storm can deposit a layer of sediment very quickly, as though this somehow proves that the entire geological record could have been produced during the mythical year-long flood described in Genesis. But the speed with which an individual layer forms tells us nothing about the intervals between successive layers. When those layers contain regular, measurable cycles produced by processes operating daily, fortnightly and seasonally, they become a record of elapsed time—and that time cannot simply be waved away.

An article in The Conversation by palaeontologist Alfio Alessandro Chiarenza of University College London describes just such a record. It concerns the Villaggio del Pescatore fossil site near Trieste, north-eastern Italy, where dinosaurs, crocodilians, fish, shrimps, plants and other organisms were preserved with exceptional detail about 80 million years ago.

Chiarenza and his colleagues, led jointly with Federico Fanti of the University of Bologna, have published their findings in the journal Global and Planetary Change. Their evidence shows that the site was not, as previously proposed, a quiet lake or sinkhole. It was a tropical tidal flat on the edge of an ancient sea, repeatedly affected by powerful monsoon floods and tropical cyclones.

The fossil-bearing limestone consists of metre-thick packages containing thousands of discrete, paper-thin light and dark layers. These had previously been interpreted as annual deposits, or varves. However, high-resolution synchrotron X-ray scanning, microscopic and geochemical analyses, and statistical analysis of the repeating patterns revealed something still more remarkable: the layers are tidal microcouplets, laid down under a semidiurnal tidal regime—two tidal cycles each day.

Moreover, variations in the thickness of the layers follow the familiar fortnightly alternation between spring and neap tides. The rocks therefore contain not merely a succession of vaguely similar bands, but an ordered astronomical rhythm produced by the interaction of Earth’s rotation with the orbit of the Moon. By counting and analysing those layers, the researchers calculated that the fossil-bearing succession accumulated over approximately 40 years. In other words, the rock preserves an almost day-by-day record extending across four decades.

That presents creationists with a problem that cannot be dismissed by claiming that “floods can deposit sediment rapidly”. Of course they can; that is precisely what some of the layers record. But a single flood cannot manufacture 40 years’ worth of successive twice-daily tidal deposits, arranged in the correct fortnightly spring–neap pattern. Still less can the supposed year-long biblical flood accommodate a geological sequence that records some 40 years of tides within one small part of a vastly larger, 80-million-year-old succession.

A paper just published in Scientific Reports by an international team led by Olev Vinn of the University of Tartu, Estonia, provides a lovely illustration of the opportunistic nature of evolution.

Some 470 million years ago — almost 470 million years before creationists’ mythical ‘Creation Week’ — a seemingly modest ecological innovation occurred in the oceans: animals began using the sheltered interiors of empty mollusc shells as habitats. This happened during the Middle Ordovician, following the Cambrian radiation, and helped to establish a new ecological niche that remains important in marine ecosystems today.

Creationists like to misrepresent the Cambrian radiation as the sudden appearance of complex, multicellular animals without ancestors. In reality, it was neither instantaneous nor without an evolutionary prehistory. It unfolded over tens of millions of years and grew out of changes already under way among the preceding Ediacaran biota, including increasing mobility, burrowing and ecological interaction.

As animals became more mobile, predation intensified and defensive structures became increasingly advantageous. Mineralised skeletons and shells evolved independently in several lineages, probably under several interacting pressures, including protection, structural support and changing ocean chemistry. Molluscs were among the groups that acquired shells, and their subsequent diversification produced such familiar forms as gastropods, bivalves and shelled cephalopods.

One consequence was the growing accumulation of empty shells on the seabed. Each dead mollusc left behind a hard surface and a sheltered cavity that other organisms could potentially exploit. Yet the researchers found that, throughout the Cambrian, the interiors of mollusc shells and other skeletal remains remained free of encrusting animals, even though organisms capable of living on surfaces inside other cavities already existed.

That changed during the Middle Ordovician, when attached animals began colonising the relatively large, spacious shells of nautiloid cephalopods. They later spread into the empty shells of gastropods and bivalves. No foresight or planning was required: once organisms capable of settling inside these shells gained access to a protected surface supplied with food-bearing water, any heritable tendency that improved their ability to exploit it could be favoured by natural selection.

New DNA Study Unlocks Origins, Social Structure of Neolithic Shimao Civilization----Chinese Academy of Sciences

In my last blog post, I pointed out that ancient Egypt’s archaeological and written record extends continuously from long before the date young-Earth creationists assign to Noah’s Flood, through that supposed catastrophe and into biblical times. Nowhere is there any sign that Egypt was destroyed by a global flood and subsequently repopulated by migrants from Mesopotamia. I also showed that the biblical writers who set stories in Egypt possessed only a tenuous understanding of its real history and culture.

Ancient China presents creationists with much the same problem. Its archaeological record contains long regional sequences extending across the supposed date of the Flood, with local populations, cultures and economies continuing to develop. If every human outside Noah’s immediate family had been exterminated, the existing peoples of East Asia should disappear from the record and be replaced by a rapidly expanding population of recent Mesopotamian origin. That is not what archaeology shows—and ancient DNA now provides an especially clear test of the claim.

The evidence comes from a paper published in Nature in November 2025 by an international team led by Professor Qiaomei Fu of the Institute of Vertebrate Paleontology and Paleoanthropology (IVPP) at the Chinese Academy of Sciences, working with researchers from several other Chinese institutions.

The team analysed genome-wide data from 169 ancient individuals recovered from Shimao and surrounding settlements in northern China. Population analyses were conducted using 144 unrelated individuals, while the remaining close relatives enabled the researchers to reconstruct pedigrees extending across as many as four generations.

Shimao, in northern Shaanxi Province, was one of the largest fortified settlements in Late Neolithic China. Occupied from approximately 2300 to 1800 BCE, it covered about four square kilometres and contained massive stone walls, separate inner and outer enclosures, specialised craft production, elite cemeteries and unmistakable evidence of a highly stratified society. Its occupation therefore began at about the very time when, according to the conventional young-Earth creationist chronology, the world should have been struggling to recover from a global extermination and repopulation by Noah’s immediate descendants.

Instead, the genomes showed that the people associated with Shimao were predominantly descended from populations already living in northern Shaanxi at least 1,000 years earlier. Those earlier inhabitants were associated with the Yangshao cultural tradition of the Yellow River’s Loess Plateau. The researchers found regional genetic continuity from the Middle to the Late Neolithic—continuity extending from before the supposed Flood into the centuries following it.

This was not a completely isolated or genetically static population. The researchers detected continuing contact with Yumin-related people from Inner Mongolia, close connections with the contemporary Taosi population farther south, and some ancestry from southern East Asian populations, possibly associated with the northward spread of rice cultivation. These were the ordinary movements, exchanges and intermarriages expected among neighbouring prehistoric farming and pastoral communities. They did not interrupt the dominant local ancestry, and there was no sign of wholesale population replacement by descendants of a family recently arrived from Mesopotamia.

The genetic evidence also revealed much about the organisation of Shimao society. Pedigrees reconstructed from elite burials indicated a predominantly patrilineal system in which status and wealth commonly passed from high-ranking men to their sons. Male members of these lineages showed relatively little diversity in their Y-chromosome ancestry, whereas the women displayed much greater mitochondrial diversity. This is consistent with women frequently marrying into communities dominated by established male lineages, although the evidence for strictly patrilocal residence remains suggestive rather than conclusive.

The study also uncovered a possible sex-related pattern in Shimao’s practice of human sacrifice. Nine of the ten sampled victims buried beneath the East Gate were male, contradicting earlier identifications based on skeletal anatomy. In contrast, most sampled sacrificial victims accompanying elite burials were female: six of seven at Hanjiagedan and fourteen of nineteen at Huangchengtai. This suggests that male and female victims may have been selected for different rituals conducted in different places, although the researchers caution that the number of genetically sexed victims remains too small to establish the pattern conclusively.

Creationism Refuted - The Unbroken History Of Egypt

Warrior princesses of ancient Egypt? Skeletons show women used the weapons buried with them

The writers and editors who composed the Pentateuch clearly possessed some knowledge of Egypt. It was, after all, a powerful neighbouring civilisation with which the peoples of the Levant had interacted for centuries. But a sprinkling of Egyptian names, loanwords and geographical details does not turn a theological story into an accurate historical account. When the biblical narratives are compared with Egyptian records, chronology and archaeology, Egypt often appears less as a real country than as an exotic stage on which the authors could set their morality tales.

The biblical use of the word ‘Pharaoh’ illustrates the problem, although not for the reason sometimes claimed. ‘Pharaoh’ is not a Hebrew expression meaning ‘owner of an estate’. The Hebrew par‘ō was borrowed from the ancient Egyptian pr-ꜥꜣ, meaning ‘Great House’. It originally referred to the royal palace and only during the New Kingdom came to be used for the king himself. Its use as the personal designation of a ruler in Genesis, whose supposed events are conventionally placed centuries earlier, is therefore probably anachronistic.

More revealingly, the biblical authors never identify the rulers in the Joseph or Exodus stories by any of their regnal names. Egyptian kings possessed elaborate formal titles and names, yet the Bible gives us only an anonymous ‘Pharaoh’. This makes it impossible to place either story securely within Egyptian chronology and contrasts sharply with the detailed records left by the Egyptians themselves.

There is likewise no independent evidence for an Exodus on anything resembling the scale described in the Bible. No Egyptian record mentions ten devastating plagues, the death of the firstborn, the destruction of a substantial chariot force or the sudden flight of an enormous enslaved population. Egyptian royal inscriptions were selective and rarely advertised defeats, so their silence alone would not be conclusive. However, there is also no corresponding demographic, economic or archaeological disruption in Egypt, and no material trace in Sinai of the immense population demanded by a strictly literal reading of the story.

The narrative also contains striking internal difficulties. Exodus 9 describes a pestilence affecting the Egyptian livestock in the fields—including horses—and then declares that ‘all the livestock of the Egyptians died’. Yet the same chapter subsequently refers to more Egyptian livestock, while Exodus 14 has Pharaoh assembling 600 chosen chariots, together with his other chariots, all of which would have required teams of surviving horses. Apologists can invent unmentioned groups of sheltered or unaffected animals, but that is an attempt to repair the story, not a literal reading of what it says.

Nor is the geography as straightforward as the familiar Sunday-school version suggests. The Hebrew Yam Suph, traditionally translated as the Red Sea, more probably means the ‘Sea of Reeds’, and its intended location remains uncertain. Moreover, at the dates commonly proposed for an Exodus, Egypt maintained forts, roads and mining operations in Sinai and exercised imperial control over much of Canaan. Even after leaving Egypt proper, the Israelites would not necessarily have escaped Egyptian power.

Exodus 12:37 gives a figure of about 600,000 adult men, besides women and children. Read literally, that implies a total population of perhaps two or three million people, together with their animals. It is absurd to imagine such a population living and travelling in Sinai for 40 years without leaving campsites, hearths, tools, pottery, animal bones, human burials or any other archaeological footprint remotely commensurate with its supposed size.

An even greater problem for biblical literalists is the continuous archaeological record of Egypt itself. Young-Earth creationist chronologies commonly place their global Flood somewhere around the middle of the third millennium BCE, by which time Egypt had already been a unified state for centuries and the great pyramids of the Old Kingdom had been built. Egyptian society certainly underwent political and economic changes, but there is no point at which its entire population disappears and is replaced by descendants of eight survivors from Mesopotamia.

Nor is there a synchronous horizon of catastrophic erosion, inundation, mass death and repopulation throughout Egypt—or anywhere else—that could represent a global Flood. Instead, archaeologists find settlements, tombs, temples, administrative records and evolving cultural traditions extending through and beyond the period in which the Flood supposedly occurred. It is a vast body of mutually consistent evidence that simply could not exist in its present form if the biblical story were literal history.

Creationism Refuted - How The Building Blocks Of Life Can be Made Without Magic

Creationist objections to abiogenesis often smuggle in the long-discredited idea of vitalism: the belief that living matter contains some special ingredient or “vital force” absent from non-living matter. This appears to lie behind the familiar creationist refrain that “life cannot come from non-life”, as though “life” were a substance that must be added to matter by a supernatural agent.

The word “life”, however, is rarely defined in this argument. Scientists can devise operational definitions for particular purposes, but life is not a single substance possessed by some molecules and absent from others. It is a collection of properties displayed by sufficiently organised chemical systems. By leaving the term undefined, creationists turn their assertion into a slogan that can neither be tested nor falsified.

The distinction between organic and inorganic chemistry is useful, but partly conventional and historical. Organic chemistry deals broadly with carbon compounds, although some carbon-containing substances—including carbon dioxide, carbon monoxide and carbonates—are traditionally classified as inorganic. There is no fundamental physical boundary between the two categories: both obey precisely the same laws of physics, chemistry and quantum mechanics.

Carbon’s extraordinary chemical versatility follows from its atomic structure. A carbon atom has six protons and six electrons, four of which are valence electrons in its outer shell. Its small size and ability to form strong covalent bonds with itself and with elements such as hydrogen, oxygen and nitrogen allow it to form stable chains, rings, branches and extensive molecular networks. Depending on how it is bonded, carbon can adopt tetrahedral, trigonal-planar or linear arrangements and can form single, double or triple bonds. All this follows from quantum chemistry; no vital spark, magical ingredient or special rule is required.

None of that proves that the origin of life was inevitable, and science does not yet possess a complete account of every stage of abiogenesis. What it does show is that there is no known chemical or physical barrier preventing non-living chemistry from becoming progressively more complex. Under suitable conditions, chemical systems can acquire such properties as compartmentalisation, catalysis and molecular replication. Once populations of replicating systems existed with heritable variation, natural selection could favour those that survived longer, reproduced more reliably and used available resources more efficiently.

One important question is where the organic raw materials involved in this prebiotic chemistry came from. Some could have formed on the early Earth, but organic compounds are also widespread throughout the Solar System and interstellar space. They have been detected in comets and asteroids and regularly occur in meteorites. Earth may therefore have received substantial quantities of organic material from several extraterrestrial sources. This raises another scientific question: what natural chemical and physical processes produced and modified that material in space?

Linda Losurdo, a PhD candidate in materials and plasma physics in the School of Physics at the University of Sydney, Australia, has investigated part of that question with her supervisor, Professor David McKenzie. They recreated some of the energetic, near-vacuum conditions associated with stars and other astrophysical environments inside glass tubes. After evacuating the tubes, they introduced nitrogen, carbon dioxide and acetylene and subjected the mixture to an electrical potential of about 10,000 volts for approximately an hour, producing a plasma known as a glow discharge.

Refuting Creationism - Last Nail In The Coffin Of Creationism's Thermodynamics Fallacy

Order From Disorder

The Gravity from Entropy theory offers new clues for reconciling gravity with the second law of thermodynamics - Queen Mary University of London

Creationists have been claiming for decades that evolution must be impossible because it supposedly requires a decrease in entropy, in violation of the second law of thermodynamics. As with so many creationist arguments, this one depends upon misrepresenting the science, confusing several different meanings of “information” and “order”, and quietly omitting the conditions under which the law applies.

The second law does not say that entropy can never decrease anywhere. It says that the total entropy of an isolated system cannot decrease. Entropy may decrease in one part of a system provided that an equal or greater increase occurs elsewhere. A refrigerator, for example, reduces the entropy of its contents by transferring heat into the room, where its motor and cooling coils generate still more heat. The contents become colder and more ordered, but the total entropy of the refrigerator and its surroundings increases.

Strictly speaking, a “closed” system is one that can exchange energy, but not matter, with its surroundings. An “isolated” system exchanges neither. Earth is not isolated: it is continually receiving concentrated, high-temperature energy from the Sun and radiating more diffuse, low-temperature infrared energy into space. That energy flow powers weather systems, ocean currents, photosynthesis and almost every ecosystem on the planet. Organisms, meanwhile, are open systems that take in energy and matter and release heat and waste.

Consequently, the maintenance and growth of biological complexity do not require the entropy of the universe—or even that of Earth as a whole—to decrease. Organisms maintain their internal organisation by consuming free energy and exporting entropy into their surroundings. Every growing tree, developing embryo and reproducing bacterium does this without so much as inconveniencing the second law.

Nor is biological “information” simply the opposite of thermodynamic entropy. Genetic information refers to sequences and their biological effects, whereas thermodynamic entropy concerns the number and distribution of microscopic physical states available to a system. Treating the two as interchangeable because both employ the word “information” is not physics; it is wordplay.

Gravity makes the creationist caricature still less defensible. A diffuse cloud of gas can collapse under gravity to form a highly structured star and planetary system. To the unaided eye, this looks like disorder turning into order. Yet the collapse releases enormous quantities of heat and radiation, increasing the entropy of the wider system. Visible organisation and thermodynamic entropy are not simple opposites, especially when gravity is involved.

Now, a paper published in Physical Review D by Professor Ginestra Bianconi of Queen Mary University of London takes this relationship between gravity, information and thermodynamics much further. As Queen Mary University explains in its accompanying news release, Bianconi’s proposed “Gravity from Entropy” theory treats gravity as arising from information encoded in the interaction between matter and the geometry of spacetime.

Refuting Creationism - Death More Than 66 Million Years Before Mythical 'Sin'

"The Bite"

Rare fossil at Montana State’s Museum of the Rockies records Tyrannosaurus attack

A paper published on 17 February 2026 in PeerJ by Taia C.A. Wyenberg-Henzler of la of Montana State University, USA, reports on a remarkable fossil from the Hell Creek Formation of eastern Montana: a nearly complete, articulated skull of an adult Edmontosaurus annectens with the broken tip of a tyrannosaur tooth still embedded in its left nasal bone.

The fossil dates from the closing stages of the Late Cretaceous, roughly 66 million years ago, shortly before Edmontosaurus, Tyrannosaurus and all other non-avian dinosaurs disappeared during the Cretaceous–Palaeogene mass extinction. The bone surrounding the embedded tooth shows no evidence of healing or remodelling, indicating that the bite occurred at, very near or shortly after the death of the Edmontosaurus.

In other words, this is physical evidence of a violent interaction between predator and prey tens of millions of years before humans existed—precisely the sort of evidence that creationists are conditioned to reject because it cannot be accommodated within their mythology. According to young-Earth creationism, there was supposedly no death, predation or suffering before human ‘sin’ allowed evil to enter the world and ruin their omnipotent creator’s previously perfect creation—apparently without that omnipotent creator either foreseeing or preventing it. And all this supposedly happened only 6,000–10,000 years ago, shortly after ‘Creation Week’.

The doctrine that no animal died before ‘the Fall’ is not stated explicitly anywhere in the Bible. It is a theological inference imposed upon the text because young-Earth creationism requires it. It belongs to the category of reasoning that says: ‘This must be true for the rest of my beliefs to be true; my beliefs cannot be wrong; therefore, this must also be true.’

Having granted themselves this assumption of infallibility, creationists must then protect it from every fact that contradicts it. The belief cannot be mistaken, so the evidence must somehow be misunderstood, fraudulent, planted by Satan, created with the appearance of age or otherwise unworthy of consideration. Anything, in fact, is preferable to the intellectually honest admission that the belief itself has been falsified.

In almost every other field of human endeavour, such a supremely arrogant claim to personal infallibility would be laughed at and its proponent told to grow up. Yet, when packaged as religious faith, it is not merely tolerated but frequently treated with respect. Its advocates demand—and often receive—special privileges and social status: ‘You must listen to me, allow me to make laws governing your life and let me shape society according to my beliefs because I have an invisible friend and wear special robes.’

And so creationism staggers on, obliged to deny a veritable deluge of scientific evidence rather than concede that its mythology bears no resemblance to the history of life on Earth.

We Can Tell The Bible Was Written By Ignorant People - Not Just By What's In It, But By What Isn't

Brazil’s highland forest has been shaped by climate change and Indigenous people for 6,000 years

One of the clearest indications that the Bible was written by people with a severely limited knowledge of the world is, in addition to the factual errors in it, such as Earth being flat with a dome over it, there is the evidence of what is not in it. Its authors wrote as though the small part of the ancient Near East familiar to them was effectively the whole inhabited Earth, so there is nothing in the Bible from outside a small area around the Middle East. They had no conception of a southern hemisphere, knew nothing of continents such as South America, and had no awareness of the peoples, cultures and complex histories that had existed there for thousands of years.

That parochial view of the world is exposed every time archaeologists and palaeoecologists reconstruct the history of regions the Bible’s authors did not even know existed. Far from being a divinely inspired account of the whole planet, the Bible reflects the geographical horizons and cultural assumptions of the scientifically illiterate people who composed it.

The latest example comes from the cold highlands of southern Brazil, where an international team of researchers has reconstructed how climate, fire and Indigenous land management shaped the distinctive mosaic of Araucaria forest and campos grassland during the past 6,000 years. The research is described by Oliver J. Wilson, a lecturer in the School of Natural Sciences at the University of Lincoln, in an article in The Conversation and was published in Scientific Reports.

The researchers combined several independent sources of evidence: pollen and microscopic charcoal preserved in continuously accumulating bog sediments, radiocarbon-dated archaeological evidence, a rainfall record preserved in a cave speleothem, and ecological models showing how the forest should have responded to climatic change. Together, these sources reveal a detailed history of gradual climatic shifts, changing fire regimes, forest expansion and human modification of the landscape.

Refuting Creationism - How Physics Constrained The Evolution Of Flight in Flies

Why most flies fly alike | WUR

Carlos Faulquier

As a child growing up in the relative silence of a North Oxfordshire hamlet, I could sometimes hear bats overhead. On a still summer night, lying in the quiet of my bedroom, I could also make out the distinctive, high-pitched whine of a mosquito as it approached an exposed arm, guided at close range by body heat as well as by carbon dioxide and human odours. Both sounds now lie beyond what my ageing ears can detect. The relevance of that mosquito’s whine will become apparent shortly.

A paper published on 9 July 2026 in PLOS Biology by scientists from Wageningen University in the Netherlands and Aix-Marseille Université in France explains how aerodynamic constraints have channelled the evolution of flight across the Diptera — the order of insects that includes houseflies, fruit flies, mosquitoes, midges and crane flies.

The researchers examined the body and wing morphology of 133 species and recorded the hovering flight of 46 of them using high-speed stereoscopic cameras. They then used computational fluid dynamics to reconstruct the aerodynamic forces and energy costs associated with their wing movements.

They found that wing shape varied considerably and was strongly influenced by evolutionary ancestry, but that wingbeat movements were broadly conserved across most of the order. Despite the enormous diversity of dipterans in size, appearance, habitat and ecology, most have evolved strikingly similar flight mechanics because the physical requirements of remaining airborne restrict the range of workable solutions.

Evolution, of course, depends upon heritable variation, but not every imaginable variation is viable or advantageous. A change that demands more energy without providing some compensating benefit is unlikely to spread through a population. Natural selection therefore tends to channel evolution towards a comparatively narrow range of effective solutions. In this case, the need to generate sufficient lift while limiting aerodynamic power consumption has produced a broadly shared flight pattern across most dipterans.

It must be galling for those few creationists who can read and understand scientific papers, yet are still eagerly awaiting the long-promised day when biologists abandon “Darwinism” and embrace creationism, to encounter paper after paper such as this one. Once again, evolutionary theory provides the accepted framework within which the observations make sense, without so much as a hint that the researchers are preparing to replace it with supernatural magic.

An enterprising creationist might nevertheless seize upon the apparent exceptions. Mosquitoes and their close relatives, the midges, do not follow the usual energy-saving pattern. Mosquitoes can beat their wings as many as 1,000 times each second, using almost three times as much aerodynamic power as similarly sized fruit flies. Crane flies also depart from the general pattern, although in the opposite direction, having evolved unusually economical flight.

Surely, the creationist might argue, if aerodynamic constraints channelled the evolution of the other flies, mosquitoes should have been constrained in precisely the same way. If an exception exists, perhaps there is something wrong with the theory.

But this objection rests on the mistaken assumption that natural selection must optimise every characteristic for a single purpose. Evolution does not produce organisms in which each structure is independently perfected. It produces compromises between competing demands, with reproductive success ultimately determining which combination of costs and benefits persists.

The researchers found that mosquitoes and midges produce disproportionately powerful sounds for insects of their size. Their rapid, low-amplitude wingbeats generate increased aerodynamic drag and require enlarged flight muscles, making flight more energetically expensive. That apparent inefficiency, however, may provide a substantial reproductive advantage because acoustic communication plays an important part in their courtship.
