Interspecies competition led to even more forms of ancient human – defying evolutionary trends in vertebrates | University of Cambridge

The gulf between science and creationism continues to widen with the publication of an open access research paper in Nature Ecology & Evolution in which the two authors argue that early hominins speciates as a result of inter-species competition, but not like most vertebrates through competition for niches, but because the evolution of technology enabled species to evolve quickly into new niches with what amounts to memetic evolution, i.e., evolution of cultures which, in an intelligent species can occur much more quickly than the slow, genetic evolution in other species.

In this respect the pattern of early hominin evolution was more like that of beetles evolving on an island.

Creationists, by contrast, as still stuck desperately looking for evidence that all humans are descended from a single pair of humans who were magically made from dirt just a few thousand years ago.

The researchers, Laura A. van Holstein and Robert A. Foley of the Leverhulme Centre for Human Evolutionary Studies, Department of Archaeology, University of Cambridge, Cambridge, UK, explain their research in a Cambridge University new release:

Seed ferns: Plants experimented with reticulated leaf venation 201 million years ago

Check any plan leaf and it will normally be one of two types - the monocotyledons with parallel leaf veins and the dicotyledons with a network of veins organised around a central vein with regular branches.

But this has not always been so. As a team of researchers at Vienna University, in collaboration with colleagues from the National Museum of Natural History in Stockholm and the Hebrew University in Jerusalem, have discovered, plants seem to have evolved the network pattern of leaf several times over the course of their evolution with most of them becoming extinct fairly quickly on an evolutionary timescale.

Their findings are published, open access, in the journal New Phytologist and explained in a University of Vienna news release:

Sometimes you wonder whether creationists ever stop to think whether what they believe is rational, then you realise that most of them are from America where parochial ignorance and cultural chauvinism are the norm. They can believe, for example, that a global flood which left ancient cultures intact and their artifacts just where they left them, and which failed to lay down the predictable global layer of sediment full of jumbled fossils was still a global flood because er... Grand Canyon.

So, news that Australian archaeologists have unearthed potshards from 6,500 years ago in a shell midden which can be accurately dated (unlike potshards), will almost certainly pass unnoticed by the majority of American creationists.

But for those few who are interested in the truth, here is an article by Sean Ulm Sean Ulm, Director, ARC Centre of Excellence for Indigenous and Environmental Histories and Futures, James Cook University, Ian J.

Macroalgal deep genomics illuminate multiple paths to aquatic, photosynthetic multicellularity: Molecular Plant

What are the main types of algae and how do they differ? Algae are classified into several main groups based on their characteristics, including pigmentation, cellular structure, and mode of reproduction. The main types of algae include:

1. Diatoms (Bacillariophyta):
   • Diatoms are single-celled algae characterized by their unique glass-like silica cell walls called frustules.
   • They are typically found in freshwater and marine environments.
   • Diatoms are important primary producers and play a significant role in the global carbon cycle.
2. Green Algae (Chlorophyta):
   • Green algae encompass a diverse group of algae that are mostly freshwater but also found in marine and terrestrial environments.
   • They contain chlorophyll a and b, giving them a green color, similar to land plants.
   • Green algae can be unicellular, colonial, filamentous, or multicellular, with a wide range of morphologies.
3. Red Algae (Rhodophyta):
   • Red algae are predominantly marine algae, although some species can also be found in freshwater.
   • They contain pigments like chlorophyll a and various accessory pigments, including phycobiliproteins, giving them shades of red, pink, or purple.
   • Red algae often have complex multicellular structures and are important contributors to coral reef ecosystems.
4. Brown Algae (Phaeophyta):
   • Brown algae are primarily marine algae, commonly found in cold-water habitats.
   • They contain chlorophyll a and c, along with fucoxanthin, which gives them their characteristic brown color.
   • Brown algae can range from small filamentous forms to large, complex seaweeds like kelps.
5. Blue-Green Algae (Cyanobacteria or Cyanophyta):
   • Despite being called algae, cyanobacteria are actually prokaryotic organisms, classified within the domain Bacteria.
   • They are photosynthetic and often form colonies or filaments.
   • Cyanobacteria can be found in diverse habitats, including freshwater, marine environments, soil, and even extreme environments like hot springs.
   • Some cyanobacteria can produce toxins under certain conditions, leading to harmful algal blooms (HABs) and posing risks to aquatic life and human health.

These main types of algae differ in their pigmentation, cellular structure, habitat preferences, and ecological roles. While some are beneficial and essential for ecosystem health, others can become problematic under certain conditions, such as nutrient pollution or climate change. Understanding the characteristics and ecological functions of different types of algae is crucial for managing and conserving aquatic ecosystems.

Today’s refutation of creationists dogma comes in the form of an open access paper just published in the Cell Press journal, Molecular Plant. Research biologists have revealed how multicellularity evolved several times independently in algae, and how many of the new genes were acquired initially by viruses.

This gives the lie to creationist claims that new information can't arise in the genome because of some half-baked confusion of information with energy and a nonsensical assumption that new genetic information would need to come from nothing.

And of course, like about 99.99% of the history of life on Earth, it all happened in that very long period of pre-'Creation Week' history between Earth forming in an accretion disc around the sun and creationism's little god creating a small flat planet with a dome over it in the Middle East out of nothing, according to creationist mythology

In information provided by Cell Press ahead of publication, the scientists at New York Abu Dhabi University and Technology Innovation Institute, United Arab Emirates, said:

A deep dive into macroalgae genetics has uncovered the genetic underpinnings that enabled macroalgae, or "seaweed," to evolve multicellularity. Three lineages of macroalgae developed multicellularity independently and during very different time periods by acquiring genes that enable cell adhesion, extracellular matrix formation, and cell differentiation, researchers report April 12 in the journal Molecular Plant. Surprisingly, many of these multicellular-enabling genes had viral origins. The study, which increased the total number of sequenced macroalgal genomes from 14 to 124, is the first to investigate macroalgal evolution through the lens of genomics.

This is a big genomic resource that will open the door for many more studies. Macroalgae play an important role in global climate regulation and ecosystems, and they have numerous commercial and ecoengineering applications, but until now, there wasn't a lot of information about their genomes.

Macroalgae live in both fresh and seawater and are complex multicellular organisms with distinct organs and tissues, in contrast to microalgae, which are microscopic and unicellular.

There are three main groups of macroalgae -- red (Rhodophyta), green (Chlorophyta), and brown (Ochrophyta) -- that independently evolved multicellularity at very different times and in very different environmental conditions.

Rhodophytes and Chlorophytes both evolved multicellularity over a billion years ago, while Ochrophytes only became multicellular in the past 200,000 years.

To investigate the evolution of macroalgal multicellularity, the researchers sequenced 110 new macroalgal genomes from 105 different species originating from fresh and saltwater habitats in diverse geographies and climates.

The researchers identified several metabolic pathways that distinguish macroalgae from microalgae, some of which may be responsible for the success of invasive macroalgal species.

Many of these metabolic genes appear to have been donated by algae-infecting viruses, and genes with a viral origin were especially prevalent in the more recently evolved brown algae.

They found that macroalgae acquired many new genes that are not present in microalgae on their road to multicellularity.

For all three lineages, key acquisitions included genes involved in cell adhesion (which enables cells to stick together), cell differentiation (which allows different cells to develop specialized functions), cell communication, and inter-cellular transport.

Many brown algal genes associated with multicellular functions had signature motifs that were only otherwise present in the viruses that infect them. It's kind of a wild theory that's only been hinted at in the past, but from our data it looks like these horizontally transferred genes were critical factors for evolving multicellularity in the brown algae.

Creationism in Crisis - Another Mystery Solved By Science - Giant Ichthyosaurs From 250 Million Years Before 'Creation Week'

Do some mysterious bones belong to gigantic ichthyosaurs? — University of Bonn

The thing about disagreements in science is that they aren't used as an excuse for persecution and schism, based on the notion that the side with the most power or the most followers wins as though truth can be determined by violence or opinion polls. In science, disagreements lead to discovery because in scientific debate the fact are, or should be, neutral, so they can referee the debate. The side with the evidence wins and the losers graciously accept that they were wrong.

This is the case of the long-standing disagreement in palaeontology over the mystery of giant bones which regularly turn up in deposits on Europe, which were first discovered in 1850 by the British naturalist Samuel Stutchbury, who reported finding a large cylindrical bone in Aust Cliff, near Bristol, UK. Similar fossils have also been found at sites around Europe, including Bonenburg in North Rhine-Westphalia, Germany and Provence, France. Stutchbury assumed they were from an extinct crocodile-like land animal, labyrinthodontia, but others disagreed. Other candidates were long-necked sauropods and an as yet unidentified, large dinosaur.

Not the mystery may have been solved by two palaeontologists working at the University of Bonn, Germany. They have published their findings, open access, in the journal PeerJ and explain it in a Rheinische Friedrich-Wilhelms Universität Bonn news release:

Today's incidental refutation of creationism comes to us from an international team of palaeontologists led by scientists from the University of Birmingham. They have shown how an early jawless fish was feeding, almost 400 million years before creationism's little pet god decided to create a small flat planet with a dome over it in the Middle East, in what creationists refer to as 'Creation Week'.

The researchers have used CT scanning techniques to construct a 3D image of the mouth-parts of Rhinopteraspis dunensis, an early, heavily-armoured boney fish that lived some 380 million years ago.

New Fossils Change Thinking on Early Mammal Evolution | AMNH

Some 165 million years before their god created the small flat planet with a dome over it that Creationists love hearing about, early mammals were evolving into modern mammals, complete with the tiny bones called ossicles that are essential for hearing. These three small bones transmit sound across the inner ear to the auditory sense organ, the cochlea.

Changes in the mammalian dentition were key to freeing these parts of the jaw joint, according to an analysis of two Jurassic-era mammal fossils which are the subject of articles in Nature. These analyses fill a gap in our understanding of the evolution of mammalian dentition and provide evidence of the transition from part of the jaw to the auditory ossicles - the stapes, malus and incus.

Like almost all of the history of life on earth, this all happened in the very long 'pre-Creation' age when 99.99% of Earth's history happened. The discovery was made by a research team that included Jin Meng of the American Museum of Natural History. Their findings are explained in an American Museum of Natural History press release.

Creationism in Crisis - Researchers Have Discovered An Essential Step In The Evolution Of Walking

From the day its discovery was announced, Tiktaalik has been a major embarrassment for creationists because not only does it refute the claim that there are no intermediate forms, but it also belies the claim that the Theory of Evolution can't make predictions.

Not only is it intermediate between fully aquatic lobe-finned fish and terrestrial tetrapod, but its discoverers predicted exactly where it would be found in the geological column and promptly went and found it there, exactly were predicted in Canada's Ellesmere Island.

But that embarrassment is about to become even more acute.

Researchers at Penn State's Eberly College have shown that Tiktaalik's ribs were attached to its pelvis and that fact helped in the evolution of walking. The research team, co-led by Tom Stewart, assistant professor of biology in the Eberly College of Science at Penn State and Neil H Shubin, one of the discoverers of Tiktaalik, have published their findings open access in the journal Proceedings of the National Academy of Science (PNAS). It is also explained in a Penn State Eberly College news release by Sam Sholtis:

Horses lived in the Americas for millions of years – new research helps paleontologists understand the fossils we’ve found and those that are missing from the record

Those few creationists who understand the science hate the record of horse evolution found in the fossil record because it runs counter to their dogma. It shows progressive change over millions of years from a small five-toed herbivore the size of a dog, through increasing size and a progressive reduction in toes to give the modern horse which walks on the tips if a single digit on each foot.

It is a fossil record which gives the lie to creationist assertions that there are no transitional fossils since each stage is clearly intermediate between its ancestors and its descendants. Moreover, most of the evolutionary history of the horse takes place in the very long period of Earth's history from before 'Creation Week' when creationists dogma says Earth was magicked out of nothing by a magic man made of nothing who then magicked all the animals out of dirt, exactly as they are today without ancestors.

And there is more embarrassment for those creationists who like to imagine Stephen J Gould and Nilse Eldredge somehow refuted Darwinian evolution with 'punctuated equilibrium' because the evolution of the horse in North America is a perfect illustration of how Darwinian evolution can produce a local fossil record that looks like a period of 'equilibrium' followed by rapid, even sudden, change in form.

Horses originally evolved in North America before crossing over the land bridge between Alaska and Siberia into Asia where they underwent allopatric speciation and then became extinct in North America during the last Ice Age. The domesticated descendants of the Asian horse were then reintroduced to North America by European colonists during the Middle Ages and subsequently became feral. Any examination of the fossil record will now show what appears to have been a sudden change from the Pliocene horse to the modern horse around 800 years ago because the Darwinian evolution occurred not locally but in Asia, where the fossil record will show what appears to have been the sudden appearance of a Pliocene horse without ancestors and no clear relationship to anything in the local fauna.

Duckbill dinosaur discovery in Morocco – expert unpacks the mystery of how they got there

Here's something to excite creationists!

It's a fossil out of place!

Sadly though, it's not out of place in the geological column - which would falsify evolution - but out of place geographically. It's the fossil of a duck-billed dinosaur in Morocco, North Africa, but it's closest relatives appear to be from Europe, which was a long sea voyage away at the time and no obvious island chain for them to island hop on.

And to add to the mystery, the European duck-billed dinosaurs didn't evolve in Europe, but in North America, so they must have got to Europe somehow.

When the news from science is relentless in its refutation of creationism, it would have been nice to find something to give the poor beleaguered fools a few crumbs of comfort, but it was not to be. This one is just as relentless s all the others.

Once upon a time, about 10,000 years ago, a magic man made of nothing appeared from nowhere and decided to create a universe that looked like a small flat planet with a dome over it, or so some ignorant Bronze Age pastoralists told their children.

Of course, they were doing their best with what little knowledge they had of the world they lived in and its history, so they filled the gaps in their knowledge and understanding with stories, and of course got it almost entirely and spectacularly wrong.

We know this because, unlike the story-tellers from the fearful infancy of our species, we now have the knowledge and understanding that centuries of careful science has revealed to us - at least those of us with the capacity to learn and understand the science know it. This is why those still unable to believe their mummy and daddy could be wrong about the superstitions they were taught as children but have since learned some science, are increasingly calling the creation stories in the Bible allegorical or metaphorical, while those who have a more objective view dismiss then as the work of ignorant people who knew no better.

Of course, despite herculean mental efforts, none of the creation myth can be forced into an allegory or metaphor for the existence of early proto-amphibians 270 million years before the little domed universe was magicked up out of nothing, and the existence of just such an animal was shown to be a fact of history when it was examined by palaeontologists from George Washington University who examines a fossil in the collection of the Smithsonian’s National Museum of Natural History and found to be 270-million-year-old fossil of a previously unknown proto-amphibian, which they have named Kermitops gratus after Kermit the Frog.

The three scientists who made this discovery, led by Calvin So, a doctoral student at the Department of Biological Sciences, George Washington University, Washington, DC, USA, have pubished their finding open access in the Zoological Journal of the Linnean Society and explained it in a Smithsonian Museum news release:

Ancient Giant Dolphin Discovered in the Amazon | | UZH

The third in a clutch of very recent papers casually refuting the childish beliefs of the creation cult.

This one concerns a giant freshwater dolphin that inhabited the Amazon 16 million years before creationists think there was a Universe, let alone an Earth with life on it.

Tell me about the Peruvian Amazon 16 million years ago. Around 16 million years ago, during the Middle Miocene epoch, the Peruvian Amazon region would have been significantly different from its present-day appearance. This period falls within the broader geological timeframe known as the Neogene Period, characterized by significant changes in climate and biodiversity.

During this time, the Amazon basin was undergoing a transformation from a relatively dry environment to a more humid and tropical one. The climate was warmer and wetter compared to today, with vast stretches of lush tropical rainforest covering much of the region.

The landscape would have been dominated by dense forests, rich in diverse flora and fauna. Ancient ancestors of many of today's Amazonian species would have been present, including various types of plants, mammals, birds, reptiles, and insects. Megafauna such as giant ground sloths, glyptodonts, and various types of large herbivores and predators may have roamed the area.

The river systems of the Amazon basin would have been different as well, as the Andes Mountains continued to uplift and shape the landscape. However, the basic hydrological structure of the Amazon River and its tributaries would have already been established, providing the necessary water sources for the flourishing ecosystems.

Overall, the Peruvian Amazon 16 million years ago would have been a vibrant and biodiverse ecosystem, albeit with species compositions and environmental conditions differing from those of today due to ongoing geological and climatic changes over millions of years.

Tanks of the Triassic: New Crocodile Ancestor Identified | Jackson School of Geosciences | The University of Texas at Austin

In that very long period of Earth's history, long before creationism's god decided to create a small flat planet with a dome over it, and before even the dinosaurs rose to pre-eminence, another group of reptiles had evolved into armour-plated tank-like creatures with thick body-plates and fringes of curved spikes to deter predators. Some of these were later to evolve into the modern crocodiles.

Now three researchers from the University of Texas at Austin have identified a new species that lived 215 million years ago in the Triassic. The newly-identified species was found on a museum shelf where it had been since its discovery in Garza County in northwest Texas, some 30 years ago by the palaeontologist, Bill Mueller. The researchers have named the new species in his honor, as Garzapelta muelleri (Pelta = plate).

Rice paddy snake diversification was driven by geological and environmental factors in Thailand, molecular data suggests | KU News

In one of those far-away places that the simple-minded authors of the story in Genesis about a small flat Earth with a dome over it being magicked up out of nothing in the Middle East, 10,000 years ago, could never have guessed existed, and some 2.5 million years before they though Earth existed, major environmental changes were driving the diversification of a species of snake into several descendant species, just as the Theory of Evolution predicts.

If those simple-minded Bronze Age pastoralists had known about it and understood its significance in terms of the history of life on Earth and the dynamic geology of the planet, just imagine how different their imaginative tale would have been! As it was, they had to do their best with what little knowledge and understanding they had.

The snake in question was the Rice Paddy snake, otherwise known as a mud snake, and the far-away place was Thailand where the rise of the Khorat Plateau caused environmental changes that resulted in the evolutionary diversification of the Hypsiscopus genus.

The team of researchers from various American and Southeast Asian Universities, who have shown this link between environmental change and evolutionary radiation in a genus was led by Dr. Justin Bernstein, of the University of Kansas Center for Genomics. Their findings are published open access in Scientific Reports and are explained in a Kansas University news release:

Alaska dinosaur tracks reveal a lush, wet environment | Geophysical Institute

About 100 million yearsd before creationism's god decided to create a small flat planet with a dome over it to keep the water about its sky out, there were dinosaurs living in what is now northern Alaska. The problem for creationists is that the people who wrote their favourite creation myths were ignorant both of dinosaurs and Alaska so had no idea their tales needed to include something about them, which is why everything they wrote about either happened within a day or two's walk if the Canaanite Hills or were plagiarized from nearby cultures.

Now a team of paleontologists and archaeologists have discovered fossilised dinosaur footprints and the remains of plants in the Nanushuk Formation that show the climate there was warmer and wetter than today, at a time when species were migrating over the landbridge between Siberia in Asia and North America.

Unlike the Paluxy hoax, which had creationists fooled for the best part of a decade, there were no human footprints (hand-carved or otherwise) associated with these dinosaur tracks.

Because creationists will try to falsify the aging of the Nanshuk Formation, claiming the method must have been flawed to such an extent that if made 10,000 years or less look like 100 million years, here is actually how the dating was done - it’s; those dreaded zircons in volcanic deposits again, plus stratigraphy based on index fossils found in rocks of known age:

Do you have any information on the Nanushuk Formation in northern Alaska and how its age was estimated? The Nanushuk Formation is a geological formation located in northern Alaska, particularly in the North Slope region. It is primarily composed of sandstone, siltstone, and shale, and it contains significant oil and gas reserves. The formation is of great interest to geologists and petroleum geologists due to its hydrocarbon potential.

The age of the Nanushuk Formation has been estimated through various methods, including biostratigraphy and radiometric dating of volcanic ash layers within the formation. Biostratigraphy involves the study of fossil assemblages found within the rocks to determine their relative ages. By comparing the fossils present in the Nanushuk Formation to those found in other formations with well-established ages, geologists can infer the approximate age of the Nanushuk Formation.

Additionally, radiometric dating techniques, such as radiocarbon dating or uranium-lead dating, can be used to determine the absolute ages of specific minerals or volcanic ash layers within the formation. These methods rely on the decay of radioactive isotopes within the rocks to estimate the time since their formation.

Through a combination of these techniques, geologists have estimated that the Nanushuk Formation was deposited during the Late Cretaceous period, approximately 70 to 80 million years ago. However, the precise age estimates may vary depending on the specific location within the formation and the methods used for dating.

The team, led by Dr. Anthony R. Fiorillo of the New Mexico Museum of Natural History & Science, Albuquerque, USA and including Professor Paul McCarthy of University of Alaska Fairbanks (UAF) College of Natural Science and Mathematics, have published their findings open access in the journal Geosciences. It is explained in a UAF news item:

Geobiologists shine new light on Earth’s first known mass extinction event 550 million years ago | VTx | Virginia Tech

A big problem for Creationists, especially those who believe the Bible was written by an infallible creator god, so think Earth is just a few thousand years old, is that science keeps finding evidence that Earth is billions of years old, and finding fossils of the life-forms that were around then.

As though that wasn't refutation enough, a team of scientists from Virginia Tech have now explained the mass extinction that wiped out most of these early life forms several billion years ago - giving the lie that they were intelligently designed by a god with the ability of foresight. Such a god would have known about the future mass extinctions and either prevented it, designed his creations to survive it or at least waited till it was safe to create things. Creating things to go extinct is not the act of an intelligent or sane creator.

This mass extinction appears not to have been a sudden event, such as that that resulted in the extinction of the non-avian dinosaurs and large marine reptile predators, but to have occurred in two phases that resulted in a loss of about 80% of species and separated by about 10 million years.

But before creationists get over-excited, this does not mean all the Ediacarans were extinct at the Cambrian 'explosion' so the Cambrian biota had no ancestors. It means that there were still about 20% of the Ediacaran biota to evolve over the 6 million years of the Cambrian 'explosion' into the Cambrian biota.

The Ediacaran mass extinction was probably caused by falling Oxygen levels as Ediacarans that had evolved large mass to surface-area ratios suffered from a loss of oxygen more so than those which had retained a smaller mass to surface area ratio.

How this mass extinction was identified and related to changes in global oxygen levels was the subject of an open access paper in PNAS and a Virginal Tech News item:

500 million year-old fossils reveal answer to evolutionary riddle | EurekAlert!

It must be galling to the leaders of the Creationist cults when science closes yet another gap and casually refutes the misleading claims they have fooled their cult followers with. It's much easier for the frauds to play to the parochial ignorance and childish thinking of their followers who will always assume that if science can't explain something, the locally popular god must have done it, ignoring the false dichotomy fallacy underpinning that deception.

Some of the gaps are artificial, obviously, being created by Creationists from misrepresentations of the actual science, such as claiming there are no transitional fossils showing, for example, a half chimpanzee - half human, but some of them are genuine gaps in the fossil record, although these tend to be ignored by creationist frauds because it would require a detailed knowledge of the evidence to appreciate where the real gaps are, and a detailed knowledge of the evidence is something no Creationist can afford to have.

One such gap, until now, was the early evolution of skeletal animals. The first fossils of skeletal animals appeared in the fossil record 550-520 million years ago during the so-called the Cambrian Explosion, which must be one of the slowest explosions on record, occurring over several tens of millions of years, but nevertheless a period of rapid evolution and diversification into different body-plans in the early history of multicellular organisms.

Many of these early fossils are simple hollow tubes ranging from a few millimetres to many centimetres in length. However, what sort of animals made these skeletons was almost completely unknown, because they lack preservation of the soft parts needed to identify them as belonging to major groups of animals that are still alive today.

Now though, a team of palaeontologist led by Dr Luke A. Parry of the Department of Earth Sciences, University of Oxford, Oxford, UK, Dr Xiaoya Ma and PhD student Guangxu Zhang, of the Institute of Palaeontology, Yunnan University, Kunming, People's Republic of China, and Dr Jakob Vinther from the Schools of Earth Sciences and Biological Sciences, University of Bristol, UK have analysed a collection of exceptionally well preserved fossils from 514 million years ago that include four specimens of Gangtoucunia aspera with soft tissues still intact.

Just to clarify that , soft-tissue term, before Creationist quote miners misrepresent it: fossilised soft tissue is not soft. It simply means the soft tissue was preserved long enough for it to become mineralised, just as bones, shells and teeth become mineralised in fossils of hard tissue. It is not evidence that these fossils are just a few thousand years old, like Creationist fraud claim dinosaur soft tissue fossils are (they are not soft either, by the way).

Before long, we can expect Creationists to either be claiming these 'soft tissues' have been carbon-dated and found to be recent, or that they haven't been carbon-dated because the scientists were afraid they would be found to be recent!

As the Oxford University News release explains:

Creationism in Crisis - Sudden Climate Change Recorded In Marine Mollusc Shells - From 8,400 Years Before Creationism's Global Genocide

Cantabrian Coast, Spain, where prehistoric people collected marine molluscs for food

In an event known to geologists as the '8.2 Ka event', i.e. 8.2 Kilo anum (thousand years) event, a sudden flow of cold water melt-water from the North American lakes into the North Atlantic stopped the 'Atlantic Conveyer' from bringing warm water from the Gulf of Mexico up to the coast of Western Europe and with it warm, moist air. This even significantly and quite suddenly changed the climate to a colder, drier weather pattern which affected marine wildlife.

That event was subsequently recorded in the shells of the marine molluscs the people living along the Cantabrian Coast of Northern Spain gathered for food, disposing of the shells in midden tips, such as in the El Mazo cave in Asturias, Spain. The 8.2 Ka event also had a profound effect on the human societies as their food disappeared or migrated to more equitable areas.

If the creationists story of a global genocidal flood were true, then this record would have been swept away and destroyed, or at least buried under the predicted layer of silt and dead animal and plant remains that such a flood would have made inevitable. But there it is, looking for all the world like there never was a global flood and not so much as a centimeter of silt covering it.

The midden in the El Mazo cave was in use for about 1500 years, producing a continuous stratigraphic record with a very high chronological resolution, which is now the subject of a paper in Scientific Reports by a team of archaeologists led by Asier García Escárzaga, current researcher from the Institute of Environmental Science and Technology (ICTA-UAB) and the Department of Prehistory of the Universitat Autònoma de Barcelona, together with Igor Gutiérrez Zugasti, from the Universidad de Cantabria (UC). The study was coordinated from the Universidad de La Rioja (UR) and the Max Planck Institute (Germany) alongside members of other academic centres (Max Planck Institute, University of Burgos, Universidad Complutense de Madrid and University of Faro).

The study applies a multidisciplinary toolkit of archaeomalacological studies and stable oxygen isotope analyses to shell remains recovered from the shell midden site.

It seems every week is a bad week for creationists, yet the wackadoodle cult staggers on, albeit with dwindling numbers, managing as always to ignore anything that shows their childish superstition to be wrong.

On top of the recently-reported predatory marine lizard, from 66 million years ago, we now have the earliest bird without the teeth of its enantiornithine ancestors. The enantiornithines were a diverse class of avian dinosaurs that went extinct 66 million years ago following the meteor impact that killed most of the dinosaurs. Only the ornithuromorphs survived, for reasons not completely understood, and they gave rise to all modern birds.

Creationists only have themselves to blame. By insisting that Earth is only 6-10 thousand years old, they are consigning the vast majority of Earth’s 3.8-billion-year history to the pre-'Creation Week' period, before they believe Earth Existed.

So, they then need to perform the most ludicrous of intellectual gymnastics to avoid dealing with all the evidence that they are wrong about the age of Earth and wrong about their denial of what else that evidence shows. For example, there is no way a 66-million-year-old fossil of a marine lizard could be assimilated into creationist superstition, so their only recourse is to devise a way to dismiss it. Favorite tactics are straight denial; bear false witness against the scientists by impugning their honesty and professional integrity; claim, without any evidence to support it, that the dating methods were so flawed they somehow made 10,000 or less look like 66 million.

But the fact remains, no matter that creationists stamp their feet and cover their eyes and ears and demand the Universe changes to conform to their requirements, there were orca-sized marine lizards in the seas 66 million years ago.

This is explained in a recent paper by researchers from the University of Bath in the UK, the Marrakech Museum of Natural History, Morocco, the Museum National d’ Histoire Naturelle (NMNH) in Paris, France, Southern Methodist University in Texas, USA, and the University of the Basque Country, Bilbao, Spain. Their paper is published in Cretaceous Research and explained in a Bath University news release.

First, a little background on the dating of the phosphate deposits in Morocco where the fossils were found:
