It's probably difficult to embarrass a Creationist, who will have a well-rehearsed routine for dismissing any evidence he/she doesn't want to be true, but if anything should, it's evidence that there is a continuous Chinese history dating back 30,000 years before Creationists believe Earth and the Universe were created. This culture has continued uninterrupted up to modern times, with no evidence anywhere of a genocidal global flood followed by repopulation with people from the Middle East some 4-6,000 years ago - another central belief of Creationism.

In fact, scientists have now found evidence that there was a rapid diversification of culture in China about 40,000 years ago, possibly spurred by cultural and genetic hybridization, when early Homo sapiens who had migrated out of Africa were encountering the Denisovans and Neanderthals. The Denisovans are believed to have been descended from an earlier dispersal out of Africa, probably by H. erectus - H. erectus being the probable parent or grandparent species of both Neanderthals and Denisovans, and probably at least one more species of archaic Eurasian hominin whose existence has been inferred from DNA evidence.

The evidence of this cultural diversification is being found at the Xiamabei archaeological site in the Nihewan Basin of northern China. It is described in a recent paper published in Nature by an international team of paleoanthropologists including scientists from Hebei Provincial Institute of Cultural Relics and Archeology, Shijiazhuang, China, the Chinese Academy of Sciences, Beijing, China, the Institut Català de Palaeoecologia Humana i Evolució Social (IPHES-CERCA), Tarragona, Spain, the Universitat de València, Valencia, Spain, and the Max Planck Institute for the Science of Human History, Jena, Germany.

The findings and their significance are explained in a Max Planck Insitute press release:
When did populations of Homo sapiens first arrive in China and what happened when they encountered the Denisovans or Neanderthals who lived there? A new study by an international team of researchers opens a window into hunter-gatherer lifestyles 40,000 years ago. Archaeological excavations at the site of Xiamabei in the Nihewan Basin of northern China have revealed the presence of innovative behaviors and unique toolkits.

The discovery of a new culture suggests processes of innovation and cultural diversification occurring in Eastern Asia during a period of genetic and cultural hybridization. Although previous studies have established that Homo sapiens arrived in northern Asia by about 40,000 years ago, much about the lives and cultural adaptations of these early peoples, and their possible interactions with archaic groups, remains unknown. In the search for answers, the Nihewan Basin in northern China, with a wealth of archaeological sites ranging in age from 2 million to 10,000 years ago, provides one of the best opportunities for understanding the evolution of cultural behavior in northeastern Asia.

A new study describes a unique 40,000-year-old culture at the site of Xiamabei in the Nihewan Basin. With the earliest known evidence of ochre processing in Eastern Asia and a set of distinct blade-like stone tools, Xiamabei contains cultural expressions and features that are unique or exceedingly rare in northeastern Asia. Through the collaboration of an international team of scholars, analysis of the finds offers important new insights into cultural innovation during the expansion of Homo sapiens populations.

Xiamabei stands apart from any other known archaeological site in China, as it possesses a novel set of cultural characteristics at an early date.

Cultural adaptations at Xiamabei

The ability of hominins to live in northern latitudes, with cold and highly seasonal environments, was likely facilitated by the evolution of culture in the form of economic, social and symbolic adaptations. The finds at Xiamabei are helping us to understand these adaptations and their potential role in human migration.

One of the significant cultural features found at Xiamabei is the extensive use of ochre, as shown by artefacts used to process large quantities of pigment. The artefacts include two pieces of ochre with different mineral compositions and an elongated limestone slab with smoothed areas bearing ochre stains, all on a surface of red-stained sediment. Analysis by researchers from the University of Bordeaux, led by Francesco d’Errico, indicates that different types of ochre were brought to Xiamabei and processed through pounding and abrasion to produce powders of different color and consistency, the use of which impregnated the habitation floor. Ochre production at Xiamabei represents the earliest known example of this practice in Eastern Asia.

The stone tools at Xiamabei represent a novel cultural adaptation for northern China 40,000 years ago. Because little is known about stone tool industries in Eastern Asia until microblades became the dominant technology about 29,000 years ago, the Xiamabei finds provide important insights into toolmaking industries during a key transition period. The blade-like stone tools at Xiamabei were unique for the region, with the large majority of tools being miniaturized, more than half measuring less than 20 millimeters. Seven of the stone tools showed clear evidence of hafting to a handle, and functional and residue analysis suggests tools were used for boring, hide scraping, whittling plant material and cutting soft animal matter. The site inhabitants made hafted and multipurpose tools, demonstrative of a complex technical system for transforming raw materials not seen at older or slightly younger sites.

Our findings show that current evolutionary scenarios are too simple, and that modern humans, and our culture, emerged through repeated but differing episodes of genetic and social exchanges over large geographic areas, rather than as a single, rapid dispersal wave across Asia.

A complex history of innovation

The record emerging from Eastern Asia shows that a variety of adaptations were taking place as modern humans entered the region roughly 40,000 years ago. Although no hominin remains were found at Xiamabei, the presence of modern human fossils at the contemporary site of Tianyuandong and the slightly younger sites of Salkhit and Zhoukoudian Upper Cave, suggests that the visitors to Xiamabei were Homo sapiens. A varied lithic technology and the presence of some innovations, such as hafted tools and ochre processing, but not other innovations, such as formal bone tools or ornaments, may reflect an early colonization attempt by modern humans. This colonization period may have included genetic and cultural exchanges with archaic groups, such as the Denisovans, before ultimately being replaced by later waves of Homo sapiens using microblade technologies.

Given the unique nature of Xiamabei, the authors of the new paper argue that the archaeological record does not fit with the idea of continuous cultural innovation, or of a fully formed set of adaptations which enabled early humans to expand out of Africa and around the world. Instead, the authors argue that we should expect to find a mosaic of innovation patterns, with the spread of earlier innovations, the persistence of local traditions, and the local invention of new practices all taking place in a transitional phase.
In other words, not a single founding couple or even a single founding species a few thousand years ago, let alone a culture derived from a small area of the Middle East, as Creationist dogma dictates their cult members believe, but a species and culture derived from hybrids and cross fertilisation of species that had been in existence for well over the 40,000 before they came into contact in China.

As usual with science, the revealed facts flatly contradict and refute Creationism.

Creationism in Crisis - The Bad News Continues With More on Ancient European Hominins

The Bad News Continues With More on European Hominin Lineage

Although there is still debate about how exactly they relate to one another and exactly which species some of them are, there is no comfort to be had from that for Creationists, because what is not in any doubt is that there were species of Homo alive and well 430,000 years ago - some 420,000 years before Creationist superstition says Earth was created, and, although there as yet are no fossils, evidence of tools shows that there were humans or proto-humans living in Britain up to 700,000 years ago.

In fact, there is even less comfort to be had for creationists from the doubts about in which exact taxon the different specimens should be placed, because as one species transitions over time into a descendant species, there is never a point in time where the next generation is a different species to its parents - that only happens in the rare cases of a new species arising by hybridization, or in childish Creationist parodies of the process. As I've said before, to determine the exact point of transition is like trying to determine the exact point at which green becomes yellow or blue becomes green in the following colour continuum.
And this gets even more complex because not all features evolve in lockstep, so, for example, modern Homo sapiens teeth could have been present in a hominin with an ancestral tibia - exactly what we would expect from an evolutionary process.

That problem is the essence of a study published last November, which somehow I missed at the time. It concerns the exact position of the 'Boxgrove' fossil in relation to other archaic European hominins, using the large sample of about 29 individuals from the Sima de los Huesos (Pit of Bones) site at Atapuerca, Spain. The fossil found at Boxgrove in Suffolk, UK, is normally placed in the H. heidelbergensis taxon, as indeed are many other fossils, simply because they are not, H. erectus, H. neanderthalensis or H. sapiens.

However, a comparison with the Sima de los Huesos fossils, which were also initially assigned to H. heidelbergensis but have since been reclassified on the basis of DNA analysis as early H. neanderthalensis, shows that 'Boxgrove' has many features in common with them. For example, the Boxgrove incisors fit within the range found at Sima de los Huesos, but the tibia has distinct features which suggests it belongs in a separate taxon.

The study is published, open access, in the Journal of Human Evolution. The research, by an international team of paleoanthropologists which included Professor Chris Stringer an expert in human evolution the Natural History Museum, London, and its significance is explained in the Natural History Museum's new release by Emma Caton:

We thought the first hunter-gatherers in Europe went missing during the last ice age. Now, ancient DNA analysis says otherwise

It's another bad day for Creationism. Close on the news that scientists have reconstructed the last 100 million years of the history of Earth's surface, comes news that a different group of scientists have revealed the last 30,000 years of the history of Homo sapiens in Europe.

Since Creationists are capable of holding to the belief that Earth is only 10,000 years old because ancient Bronze Age nomads who knew no better thought so, despite the fact that the last 100 million years of its history is known in detail, they should have little difficulty in ignoring the evidence that Europeans have a known history stretching back three times longer than they believe Earth has existed. After all, what is a mere 30,000 years when 100 million years can be ignored?

In fact, we know from fossil evidence that early modern human hunter-gatherers spread out of Africa and across Eurasia beginning about 45,000 years ago. The mystery was what happened to them during period between 25,000 and 19,000 years ago when the last Ice Age was at its maximum and much of Europe was under vast ice sheets like that covering Greenland today.

Some authorities believed that European Homo sapiens disappeared during that time, but this recent research shows that they hung on in France and the Iberian Peninsula, to repopulate Europe as the ice sheets retreated north. The evidence is in the traces of their DNA now found in modern Europeans. The scientists who made this discovery have published their work in two papers, one in Nature and the other in Nature, Ecology & Evolution

One of the authors of these papers, Adam B. Rohrlach of the Department of Archaeogenetics, Max Planck Institute for Evolutionary Anthropology, Leipzig, Germany and the School of Mathematical Sciences, University of Adelaide, Adelaide, South Australia, Australia, has written about the team's research in The Conversation.

When your holy book tells you Earth is only about 10 thousand years old, but the evidence tells you there is a continuous history of the last 100 million years, it takes a special form of self-deception and denialism, amounting to a mental disorder, to cling to the tales in your holy book and continue to believe it's a text book of history and science and not really a book of stories made up by people with little science so knew no better.

So, with their tradition of science denial and rejection of any evidence they don't want to be true, it probably won't come as a surprise to Creationists that Australian scientists working with colleagues in the École Normale Supérieure (ENS), Paris, France, the Université Lyon, Villeurbanne, France, and Université Grenoble-Alpes, Grenoble, France, have published a detailed model of the changes to Earth's surface over the past 100 million years. Their model is published in the journal, Science.

How Creationism's Putative Designer COULD Have Given us Immunity to COVID-19 But Chose Not To

Genetics might explain why some people have never had COVID – but we shouldn't be too focused on finding out

Early in January, 2020, when stories of a potentially dangerous infection in China were beginning to emerge in the world's news media, my partner and I had a daytrip to London to see the Lucian Freud exhibition at the National Gallery. We drove to the Westgate Centre in Shepherd's Bush where we left the car to avoid congestion charges, then took a London Underground train to central London. It was a popular exhibition, so the gallery was crowded, as were the underground trains on our return journey during rush hour, when commuters pack like sardines into the trains.

The following day, my partner developed a cough and a fever and was quite ill for several days with what we thought then was a nasty cold. Two weeks later, I developed the same symptoms and was quite ill for about 48 hours.

Had we had those symptoms today, we would assume we had COVID-19! That was three months before Britain went into full lock down. Since then both of us have had every vaccination offered and always observed the precautions like wearing face masks, regularly using hand cleanser, avoiding crowds, regular testing, even leaving anything delivered to the house for several hours before touching it, and we haven't had so much as a cold.

Did we have COVID-19, in January 2020? There is now no way of knowing, of course, but it is very unlikely that we both have a genetic immunity to the SARS-CoV-2 virus - the explanation now being offered for why some people have never been infected, despite the prevalence of the virus in the environment. The probability is that we either caught it early on and were immune during the first major wave, then had immunity from vaccinations, or we had it asymptomatically - as a high, but indeterminate number are now believed to have had.

Flamingos form cliques with like-minded pals - News

According to Creationist superstition, humans are specially created as a different form of life from the rest of creation and so are the only species capable of experiencing 'higher' emotions such as love and friendship, or of being able to empathise with other members of the same species. This superstition is vigorously maintained, probably because the cult leaders understand that it makes their dupes feel special enough, so they stick with the cult and reject any idea which seems to reduce their over-inflated sense of self-importance.

The superstition is maintained despite the growing number of examples of other species having these 'human' emotions, such as this example of flamingos forming friendship and mutual support groups depending on their personality. Flamingos with similar personalities prefer to associate together and will even defend one another if attacked by a member of another group.

Flamingos are highly gregarious and can be seen in groups ranging from a half dozen to many thousands. I have seen small flocks of maybe a dozen in Andalucia, Spain and in Kuwait, larger flocks of several thousand in the Camargue, France and probably tens of thousands on the Limasol Salt Lake, Akrotiri, Cyprus.

The research in question was carried out on a captive population of Caribbean flamingos at the Wildfowl & Wetlands Trust, Slimbridge, Gloucestershire, UK, by two scientists from Exeter University.

The research is explained in an Exeter University news release:

When scientists from the Field Museum of Natural History, Chicago, Illinois, USA, discovered a hummingbird with an iridescent gold throat, they thought they had discovered a new species, but DNA evidence revealed that it was a hybrid between two closely related species - the Pink-throated Brilliant, Heliodoxa gularis and the Rufous-webbed Brilliant, H. branickii.

The problem was that the two parent species both had pink throats, so you might expect a hybrid to have a pink throat also, not glittering gold.

The embarrassing lack of scientific research support for Creationism continues with the publication of yet another paper that utterly refutes it and exposes the fraudulent nature of the cult's claims.

Researchers led by assistant professor Emily, E. Wroblewski of Washington University in St Louis, MO, USA, have found that the closest relative of humans, the bonobo, Pan paniscus, not only suffers from malaria parasites closely related to the that infect humans - Plasmodium falciparum - but that the pattern of immunity is related to the prevalence of infections, similar to the pattern found in humans. This shows that infections can be severe enough in bonobos to reduce fitness to survive and reproduce. Natural selection, as in humans, has led to an increase in genes for immunity in bonobo populations subject to parasitism by the organisms.

The scientists have discovered that bonobo populations differ in a key immune trait depending on the presence of malaria infection. Infected populations have a higher frequency of an immune variant that protects against developing severe disease, a pattern that mirrors what is observed among human populations.

Because of the difficulty in monitoring wild bonobos and particularly in obtaining blood samples to analyse for malaria parasites and bonobo DNA, the team used the ingenious method o c collecting fecal samples which contain both the parasite and bonobo DNA.

The animals and plants that only exist in captivity – and why time is running out to restore them to the wild

In southern Ontario, Canada, in 1866, a flock of migrating passenger pigeons, was estimated to be 1.5 Km (.93 miles) wide and 500 Km (310 miles) long. It took 14 hours to pass and contained an estimated 3.5 billion birds. The passenger pigeon was then probably the most abundant species of bird on Earth and certainly in North America.

On September 1, 1914, at Cincinnati Zoo, less than 50 years later, 'Martha' the last known passenger pigeon died and the species became extinct. The species had been functionally extinct when the last male died some years earlier. Its death went unrecorded. The last wild passenger pigeon is believed to have been shot in 1901.

The extinction of this species was due entirely to human intervention, including hunting for cheap meat on a massive scale, deforestation and habitat destruction. Because of its habit of migrating in closely-packed flocks, a single shot could bring down several birds.

An open access paper published a couple of weeks ago in the journal Genes should have set alarm bells ringing in Creationists circles, assuming anyone in Creationist circles reads peer-reviewed science and risks having their cherished superstitions spoilt with facts.

The paper was a report on the findings of a team of researchers from the University of Illinois at Urbana-Champaign, Illinois, USA into why, during a summer 2022 outbreak of the highly infectious viral disease of white-tailed deer, Odocoileus virginianus, some deer remained unaffected while scores of others died within days of infection.

The disease, epizootic haemorrhagic disease (EHD), is caused by a double-stranded RNA virus, spread by a midge. There are outbreaks of this disease every 3-5 years.

The team sequenced the entire genome of the white-tailed deer for the first time and found variations in one particular gene associated with apparent immunity to EHD.

So, why should this concern Creationists?

Bearing in mind that Creationists insist their supposed intelligent [sic] designer is omniscient and so knows exactly what its designs will do when it designs them, if we buy into this evidence-free superstition, we have to believe:
  1. Creationist's intelligent [sic] designer designed the virus that causes EHD to kill white-tailed deer, and designed the midge to act as the vector for the disease to ensure the virus gets spread to kill new victims.
  2. It then gave some deer a modified gene which protects it from the virus it designed to kill them.
  3. It could have given all white-tailed deer this protective gene, but chose not to.
  4. Therefore the only conclusion is that it wanted most deer to be susceptible to the fatal disease it had designed to make them suffer and die.
As though that evidence of malevolence wasn't enough, what we have here is a simple example of how a mutant alle can give carriers of that mutation a significant advantage over carriers of the non-advantageous alle. It would take an exceptional degree of denialism to conclude that killing carriers of the non-protective allele while allowing carriers of the protective mutation to survive is not going to lead to an increase in the copies of that protective allele in the population gene pool over time.

In other words, what we have here is a perfect example of evolution by mutation and natural selection - the very same process that created the viral parasite in the first place. Evolution being defined by biological science as change in allele frequency in a population over time, not the childish Creationist parody of one species magically turning into another, unrelated species, in a single event.

Creationists need to explain why the patently obvious isn't true and why malevolent intent is a better explanation for these deer being killed by a virus, and Creationism's putative designer's apparent malevolent intent in creating the disease in the first place.

The research team's work was explained in a University of Illinois news release. As you read this, bear in mind that what the article is describing is what Creationists believe was created deliberately by their allegedly omniscient, omni-benevolent deity:
URBANA, Ill. – It was the height of summer 2022 when the calls started coming in. Scores of dead deer suddenly littered rural properties and park preserves, alarming the public and inconveniencing landowners. According to officials at the Urbana Park District, it was Epizootic Hemorrhagic Disease (EHD), a midge-borne viral illness that pops up in white-tailed deer populations around the state every few years. And when susceptible deer are infected, they die within days.

Now, University of Illinois scientists have found gene variants in deer associated with the animals’ susceptibility to EHD.

This is the first time this gene has been sequenced completely in white-tailed deer. This is important because without the sequences, there's no starting point to do any kind of research.

The team sequenced the gene for Toll-Like Receptor 3 (TLR3), a protein that spans membranes of intracellular organelles in immune cells and helps recognize double-stranded RNA (dsRNA) viruses. When a dsRNA virus, such as the one that causes EHD, enters the cell, TLR3 activates the host’s first immune defenses, triggering inflammation and priming the rest of the immune system.

When the team sequenced TLR3 from EHD-infected and uninfected deer, they found dozens of variable sites in the DNA known as single-nucleotide polymorphisms (SNPs). Two of the SNPs were significantly more common in uninfected deer.

Because we found mutations in TLR3 more frequently in EHD-negative animals, we think deer with these mutations are less susceptible to EHD.

Yasuko Ishida, co-author

That conclusion is rooted in the probability that many white-tailed deer in Illinois are exposed to EHD in their lifetimes, but only some will die from the disease.

In many areas, outbreaks occur every 3-5 years, when environmental conditions favor the life cycle of midges that carry the virus. The midges spend their larval stages in mud under ponds and puddles where deer drink during drought conditions. As those water sources dry up, usually during late summer, the midges’ muddy habitat is exposed and the adult flies emerge to bite and infect deer. The cycle can be interrupted locally by a soaking rain or a cold snap, which is why outbreaks don’t happen every year.

The researchers emphasize that EHD is not transmissible to humans or pets through midge bites or consumption of infected deer meat.

Although there’s not much wildlife managers can do to disrupt the cycle and prevent outbreaks in natural habitats, the team says it’s still helpful to understand the genetic underpinnings of the disease. Theoretically, deer in captive herds could be sampled to characterize the level of vulnerability to EHD, and wild herds could be sampled during the hunting and EHD-outbreak seasons, informing managers and the public of future risk.

The value of this research is that it helps inform the public about EHD. It helps them to understand not only what the disease will look like, but potentially the severity of an outbreak in a particular area. Sometimes there's value in knowing what to expect.

It’s very complicated to respond to an outbreak of EHD because there are often large numbers of deer found dead near water. People don’t know what to do when that happens, but we encourage the public to report potential EHD outbreaks to their local IDNR wildlife biologist for the surveillance and future study of the disease.

Considering the disease’s episodic nature, it’s not likely to present as a severe outbreak again in Urbana parks anytime soon. But it is an increasing threat to the state’s northern regions, including Chicagoland. Another recent study by Mateus-Pinilla, Roca, and others shows the disease has been slowly but steadily moving northward in Illinois. The researchers don’t know whether that’s due to climate change or greater reporting, but it’s clear EHD isn’t restricted to rural parts of Illinois.

Abstract

Epizootic hemorrhagic disease (EHD) leads to high mortality in white-tailed deer (Odocoileus virginianus) and is caused by a double-stranded RNA (dsRNA) virus. Toll-like receptor 3 (TLR3) plays a role in host immune detection and response to dsRNA viruses. We, therefore, examined the role of genetic variation within the TLR3 gene in EHD among 84 Illinois wild white-tailed deer (26 EHD-positive deer and 58 EHD-negative controls). The entire coding region of the TLR3 gene was sequenced: 2715 base pairs encoding 904 amino acids. We identified 85 haplotypes with 77 single nucleotide polymorphisms (SNPs), of which 45 were synonymous mutations and 32 were non-synonymous. Two non-synonymous SNPs differed significantly in frequency between EHD-positive and EHD-negative deer. In the EHD-positive deer, phenylalanine was relatively less likely to be encoded at codon positions 59 and 116, whereas leucine and serine (respectively) were detected less frequently in EHD-negative deer. Both amino acid substitutions were predicted to impact protein structure or function. Understanding associations between TLR3 polymorphisms and EHD provides insights into the role of host genetics in outbreaks of EHD in deer, which may allow wildlife agencies to better understand the severity of outbreaks.

These examples of how the childish Creationist notion of intelligent [sic] design simply makes no sense at all, are almost daily occurrences in biological science, as are the examples of evolution in progress that we see in this example of natural selection favouring immunity to a viral parasite. The basic problem with Creationism and Creationists is that facts and deductive logic are irrelevant, otherwise there wouldn’t be Creationism and Creationists.

The psychology needed to maintain a superstition despite the overwhelming evidence against it must amount to a mental disorder that can only be accounted for by intensive mental abuse in childhood that gives rise to a mind-numbing acute anxiety disorder, or psychotic theophobia. Creationism and the wilful ignorance and science denial that it requires are not normal psychological states.

To inflict this mental disorder on the vulnerable minds of children, reinforced by threats of eternal torture, is a form of coercive child abuse. As someone once said, there are good people who do good things and bad people who do bad thing, but with religion, good people can do bad things believing them to be good. Inflicting Creationism on children is a case in point.

Another gap was slammed shut by science recently and, once again, no gods were found.

The gap was in our knowledge of how exactly birds wings evolved; now two Japanese scientists from the Department of Earth and Planetary Science, Tokyo University's Graduate School of Science, Yurika Uno & Tatsuya Hirasawa, have shown that the key structure, known as the propatagium, evolved out of an analogous structure in non-avian dinosaurs.

Creationists hoping to find evidence that the Theory of Evolution is being increasingly rejected by mainstream scientists will be disappointed to find not a scrap of evidence in this paper that the TOE is other than alive and well and providing an explanation for the observable facts as well as predicting what the scientists would find and informing their research. This paper is not about whether birds’ wings evolved, but how and from what starting point.

The Tokyo University news release explains the research and its significance:

Symbiotic fungi transform terpenes from spruce resin into attractants for bark beetles | Max Planck Institute for Chemical Ecology

Whatever designed the symbiotic relationship between the European spruce bark beetle Ips typographus, the various fungi it depends on and Spruce trees, is either incompetent, severely amnesiac, or deliberately malevolent.

Briefly, the beetle grubs depend on the fungus to kill and breakdown the tissues of the spruce tree in which they live and develop into mature adults and the fungus gets carried to new trees by the beetles when they disperse. For this relationship to work, the adult beetles need to be directed to suitable new host spruces. This is achieved by the fungus producing attractive chemical known as terpenes which are detected by the beetles with a special olfactory organ. Not only that but research has shown that the fungi also produce chemicals that stimulate the beetles to burrow into the bark of the spruce hosts, so starting the infection and killing process.

All very brilliant and a triumph of 'designed', as no doubt the average Creationist will claim, even claiming that this system must have been created as a whole system, which is nonsensical, of course, as every component could have evolved gradually over time with each generation improving on the previous one, either in the sensitivity of the beetles' olfactory organ, the attractiveness of the chemicals the fungi produce or the dependence on each other for feeding and dispersal.

However, where the incompetence or malevolence of the 'designer' created by comes in is in the way the attractive chemicals are created by the fungus. A recent piece of research led by scientists at the Max Planck Institute for Chemical Ecology, Jena, Germany, has shown that the fungus uses a substance produced by the spruce tree to defend itself against fungal attack!

And it gets even more complicated because some species fungi are harmful to the beetles, so the beetles have evolved the ability to distinguish between the chemicals produced by symbiont species and ignore those produced by harmful species.

Let's just run through the logic of Creationist claims of intelligent [sic] design shown here:

On top of the treat from Marburg, highlighted in my last blog post, scientists have also identified a potential threat from deadly fungal infections which are on the rise.

Could it be that Creationism's divine malevolence is intelligently designing a fungus with which to attack humans, building on the success it has had with a fungus to attack and exterminate frogs, news and other amphibians - a problem I have written about extensively both in this blog and in my illustrated book, The Malevolent Designer: Why Nature's God is not Good.

This threat to human health is the subject of an article in The Conversation by Justin Beardsley, Associate Professor in Infectious Diseases, Sydney Institute for Infectious Diseases, Westmead Clinical School, University of Sydney, Australia.

Malevolent Designer News: Marburg - Another, Even More Deadly Pandemic in Waiting?

Marburg
Another, Even More Deadly Pandemic in Waiting?

Marburg viruses
Marburg virus particles
What is Marburg virus and should we be worried?

The World Health Organization (WHO) recently confirmed an outbreak of Marburg disease - in Kie Ntem Province of the West African country of Equatorial Guinea. Marburg disease is a haemorrhagic fever which is frequently fatal in humans. So far, 9 victims have died and a further 16 people are suspected of being infected. 200 contacts of these victims have so far been traced and put into quarantine by the WHO.

Marburg is a filovirus like the related ebola, and has a fatality ratio of 88%. It is highly infectious and easily transmitted. At the moment there is insufficient data to compare its infectivity with that of ebola.
The big concern is that this virus could break out of its endemic stronghold in West Africa and, like the SARS-CoV-2 Virus, become a major pandemic in a world in which health services are already overstretched, still dealing with the COVID-19 pandemic, which is far from over.

Embarrassingly for intelligent [sic] design Creationists, it is central to their cult think that all life is the work of their supposed designer deity, which, being omniscient, only ever designs organisms like viruses in the full knowledge of what they will do; de facto it designs them to do exactly what they do. In other words, if Marburg does become a major pandemic, that is exactly what it intended when it designed it.

The following article by Professor C Raina MacIntyre, NHMRC Principal Research Fellow, Head, Biosecurity Program, Kirby Institute, UNSW Sydney, explains what Marburg is, and discusses whether we should be worried.

Research Shows That Cleaner Wrasse Have a Sense of Self

Bluestreak cleaner wrasse, Labroides dimidiatus
Another nail has been driven into the coffin of the absurd Creationist notion that humans are a unique creation of a magic creator who endowed us with special qualities not given to other species. One of these supposed unique species is sentience, which includes a sense of self, so only humans are supposedly able to understand that they have some special purpose, while all other life-forms are unaware of, for example, their own existence and mortality.

And of course, not being sentient they are not capable of having emotions and run entirely on instinct and reflexes.

The nail was driven in quite casually and without the intention of refuting creationism, like so much else in science, simply by exposing the facts. The facts are once again diametrically opposite to what Creationists believe. The research team showed that a species of fish known as the bluestreak cleaner wrasse, Labroides dimidiatus, has a sense of self to the extent that it recognises photographs of itself by recognising its own face.

Perhaps even more surprising was the fact that, when the photograph was 'shopped' to make it look there was a parasite attached to their throat, the wrasses rubbed themselves to try to remove it! This shows a remarkable degree of self-awareness and sentience, especially since mirrors are not part of their natural environment.

The team that made this discovery was led by Professor Masanori Kohda from the Graduate School of Science at the Osaka Metropolitan University. They showed that cleaner wrasses recognise themselves in photographs the same way humans do - by recognising their own face. These fish were chosen as research subjects because they appear to recognise strangers in their midst and drive them away, while tolerating others of their own companion group. In this way individuals maintain and defend their 'cleaning stations' where other fish come to be cleaned of parasites, even from inside the mouth of predatory fish.

The research is described in the Osaka Metropolitan University press release:
A big step forward in vertebrate cognitive function research

A research team led by Specially Appointed Professor Masanori Kohda from the Graduate School of Science at the Osaka Metropolitan University has demonstrated that fish think “it’s me” when they see themselves in a picture, for the first time in animals. The researchers found that the determining factor was not seeing their own body but seeing their face. These findings have been published in the Proceedings of the National Academy of Sciences.

This study is the first to demonstrate that fish have an internal sense of self. Since the target animal is a fish, this finding suggests that nearly all social vertebrates also have this higher sense of self.

In this study, relevant experiments were conducted with Labroides dimidiatus, commonly known as a cleaner fish, which are known to be able to recognize themselves in mirrors and regularly attack other unfamiliar cleaner fish who intrude on their territory. Each cleaner fish was presented with four photographs: a photo of themselves; a photo of an unfamiliar cleaner; a photo of their own face on an unfamiliar cleaner’s body; and a photo of unfamiliar cleaner’s face on their own body. Interestingly, the cleaner fish did not attack photos with their own faces but did attack those with the faces of unfamiliar cleaner fish. Together these results indicate that the cleaner fish determined who was in the photograph based on the face in the photo but not the body in the similar way humans do.

To negate the possibility that the fish considered photographs of themselves as very close companions, a photograph mark-test was conducted. Fish were presented with a photograph where a parasite-like mark was placed on their throat. Six of the eight individuals that saw the photograph of themselves with a parasite mark were observed to rub their throats to clean it off. While showing those same fish pictures of themselves without parasite marks or of a familiar cleaner fish with parasite marks did not cause them to rub their throats.
The research and its significance are explained in the team's open access paper in PNAS:
Significance

Some animals have the capacity for mirror self-recognition, but implications for self-awareness remain controversial. Here, we show that cleaner fish, Labroides dimidiatus, likely recognize their own mirror image using a mental image of the self-face comparable to humans. Mirror-naïve fish frequently attacked photographs of both themselves and strangers. In contrast, after passing the mirror test, aggression against their own photograph and composite photographs of own face/stranger body declined, but aggression remained toward unfamiliar and composite photographs of stranger face/own body. Our results suggest that cleaner fish with MSR ability can recognize their own mirror image based on a mental image of their own face, rather than by comparing body movements in the mirror. This study demonstrates how animals recognize self-images.

Abstract

Some animals have the remarkable capacity for mirror self-recognition (MSR), yet any implications for self-awareness remain uncertain and controversial. This is largely because explicit tests of the two potential mechanisms underlying MSR are still lacking: mental image of the self and kinesthetic visual matching. Here, we test the hypothesis that MSR ability in cleaner fish, Labroides dimidiatus, is associated with a mental image of the self, in particular the self-face, like in humans. Mirror-naive fish initially attacked photograph models of both themselves and unfamiliar strangers. In contrast, after all fish had passed the mirror mark test, fish did not attack their own (motionless) images, but still frequently attacked those of unfamiliar individuals. When fish were exposed to composite photographs, the self-face/unfamiliar body were not attacked, but photographs of unfamiliar face/self-body were attacked, demonstrating that cleaner fish with MSR capacity recognize their own facial characteristics in photographs. Additionally, when presented with self-photographs with a mark placed on the throat, unmarked mirror-experienced cleaner fish demonstrated throat-scraping behaviors. When combined, our results provide clear evidence that cleaner fish recognize themselves in photographs and that the likely mechanism for MSR is associated with a mental image of the self-face, not a kinesthetic visual-matching model. Humans are also capable of having a mental image of the self-face, which is considered an example of private self-awareness. We demonstrate that combining mirror test experiments with photographs has enormous potential to further our understanding of the evolution of cognitive processes and private self-awareness across nonhuman animals.

It's worth repeating what Professor Kohda said: because this ability is present in a fish, it is likely to be present in all social vertebrates - a far cry from what Creationist frauds tell their credulous dupes to make them feel special.

Creationism in Crisis - Now Cockatoos Have Been Seen Choosing Tools For A Task

Now Cockatoos Have Been Seen Choosing Tools For A Task

Cockatoos know to bring along multiple tools when they fish for cashews -- ScienceDaily

Imagine you're a Creationist fraud trying to convince your credulous cult that a magic man in the sky made humans specially and flattering your target marks by citing our high intelligence as evidence of our difference, as though we are the only species to have something that makes us unique (like every other species has). Then along come a bunch of clever scientists and shows that another, very distantly related species, a cockatoo, is also highly intelligent.

The conclusion any sensible person is going to draw from this is that intelligence is not unique to humans but is an evolved trait that has arisen in many distantly related species such as octopuses, bees, birds, and several mammals. That it has arisen independently can be concluded from the fact that it is a relatively rare trait. If it had evolved from a remote last common ancestor of cephalopods, insects, birds and mammals it would be almost universal in the animal kingdom, not unusual.

How then do you fool a sensible person into thinking humans are unique with a unique design which includes high intelligence, when the evidence shows otherwise? Well, you don't, of course. As a dedicated confidence trickster and fraud, your target market is the lower few percentiles of the IQ curve and those whose thinking ability has been inhibited by theophobic psychosis, also known as religious fundamentalism, an acute anxiety disorder normally caused by mental abuse in childhood, so you simply ignore the evidence, confident that they are very unlikely to read it, but if they do they won’t understand its significance and will wave it aside because it doesn’t support them.

You will have targeted that demographic specifically because of their inability to evaluate complex evidence and draw valid conclusions from it, or to change their minds from those opinions foisted on them by childhood conditioning and maintained by the terror of thinking they could be wrong under the watchful eye of an invisible mind-reading sky bogeyman who has a uniquely terrifying punishment waiting for doubters.

So here then is an account of how a species of bird, the Goffin's cockatoo, Cacatua goffiniana, not only quickly learns to use two different tools to solve a problem with a two-stage solution, but then remember what tools it needs for the task and selects them to take with it when leaving to perform the task.

Faeces, urine and sweat – just how gross are hot tubs? A microbiologist explains

If there is anything Creationism's intelligent [sic] designer is notable for, it's never missing an opportunity to make more people sick with its specially designed pathological parasites. Take for example, the simple pleasure of sharing a Jacuzzi with friends and neighbours.

Of course, if it’s anything like the miserable old pleasure-hating deity of the Christian Bible or the Qur’an, the malevolent designer probably hates the idea of semi-naked people having fun in a hot tub together, drinking wine and maybe even touching one another. I'm reliably informed that Australians even make love in them!

We've often discussed the possibility of a Jacuzzi in our back garden, especially as we have nice neighbours who would undoubtedly join us in one with a glass or two of wine if invited. There are few things more relaxing than sparkling white wine and the tickle of bubbles rising up underneath you, especially on a balmy summer evening.

However, having read the following article by Primrose Freestone, Senior Lecturer in Clinical Microbiology, University of Leicester, I think I'll forego that pleasure in favour of sun loungers around a fire pit.

Creationism in Crisis - Evolution of Wheat Since the Neolithic

Creationism in Crisis

Evolution of Wheat Since the Neolithic
Awned wheat, similar to that grown for 10,000 years since first cultivated in the Neolithic

Mesopotamian wheat cultivation
The cultivation of cereals such as wheat represented a turning point in the progress of human civilisation (cylinder seal from Uruk, 3.200 BCE).
Evolution of wheat spikes since the Neolithic revolution - Universitat de Barcelona

The evolution of cultivated wheat presents challenges most Creationists will avoid if possible. The first and perhaps most obvious challenge is why has wheat needed to be improved by cultivation and human selection if, as Creationists believe, it was created by a perfect, omniscient designer for the benefit of humans? Did the designer not foresee the future needs of humans or anticipate the problem of feeding a large population from a crop with inadequate yields?

The second is that fact that, despite the ludicrous Creationists' insistence that the Theory of Evolution (TOE) is a theory in crisis, and about to be overthrown as a scientific theory by their superstition, including magic and an unproven magical entity, the only viable explanation for the changes which have occurred over time is selection by human agency, in other words a form of accelerated evolution by natural selection and primitive genetic engineering by people who knew nothing of genetics, just like the natural environment.

Awnless wheat
Awnless wheat, similar to that which first appeared about 2,000 years ago.
Archaeological records show that, for about 10,000 following the first cultivation of wild wheat in Mesopotamia about 12,000 years ago, wheat grains had long awns, then about 2000 years ago, wheat diversified into awned and awnless or very short awned varieties.

Clearly, given the length of time awned whet was grown, there was not strong selection for awnless wheat, so why did the different varieties evolve, apparently suited to different environmental conditions. This was the question a study, published in the journal Trends in Plant Science, co-led by the University of Barcelona, the Agrotecnio centre and the University of Lleida, set out to answer. Creationists might note that nowhere does magic or a magic entity appear in the explanation, which depends in its entirety on the workings of the TOE.

The research and its significance are explained in a University of Barcelona news release:

Earwigs are the hero single mothers of the insect world – and good for your garden too

Of the more than 1000 species worldwide, only four are native to the UK, with a further three introduced species.

Earwigs are often regarded as garden pests because they can and sometimes do, damage growing plants and soft fruits such as strawberries, but what is not generally recognised is that they are predators on much more destructive pests such as aphids.

But there are a few things about these fascinating insects that mean they should command our respect and protection by leaving them undisturbed.

Mistaken fossil rewrites history of Indian subcontinent for second time - News - University of Florida

It's a source of embarrassment to the scientists concerned, and no doubt a small crumb of comfort to those anti-science extremist propagandists trying to fool scientifically illiterate simpletons into thinking science is unreliable, that scientists have discovered a major mistake.

To those who understand science and how scientific opinion is always contingent and subject to revision and where nothing is ever cast in tablets of stone; where the only certainty is that there are no certainties, it is always rewarding and reassuring when mistakes are discovered and corrected because this shows the scientific method is working.

Just such an example came to light recently when scientists revisited the site where a fossil, thought at the time it was first discovered to be highly significant, had been found. What they discovered was that the ‘’ not only was nothing of the sort, but was actually in an advanced state of decay and peeling off the wall of the cave in which it had been found about a year earlier - things no self-respecting fossil should be doing.

It turned out that the 'fossil' was the recent remains of a wild honeybee (Apis dorsata) hive which, when discovered, bore a remarkable resemblance to an Ediacaran fossil, Dickinsonia tenuis, only previously known from South Australia. The implications for the age of the rock formation in which it was appeared to solve the problem of accurate dating of the rock formation and its origins in the ancient supercontinent, Gondwanaland, some 550 million years ago.
