Creationism in Crisis - How Our Extended Genome of Micro-Organisms Killed Rivals For Land During the European Imperial Expansion
In his Pulitzer Prize-winning book, Guns, Germs and Steel, Professor Jared Diamond, makes the point that it was not just superior technology (guns and steel) that enabled European imperialists to colonise much of the undeveloped world, but also our armoury of lethal germs that we unwittingly took with us.
Our germs, many of which are derived from related varieties in our domestic cattle, had being living with us for thousands of years in Europe where the population had developed a degree of natural resistance. However, when we came into contact with people who had lived, for example, on remote Pacific Islands, these people had little or no natural immunity, so diseases like measles and mumps were lethal and spread quickly, going ahead of us like a fifth column, working in secret to kill or severely weaken the indigenous population, making it easy to take control through force of arms.
This is an example of a sudden environmental change giving a big advantage to one group and being severely detrimental to a rival group. In evolutionary terms, this could be one reason why we have failed to develop complete resistance to our commensal and sometime pathogenic microbes and viruses; as we evolved, it was advantageous to us to have this invisible 'fifth column' to help us take over new territory. It's a classic example of how genes can form alliances and don't even need to belong to the same species, just so long as both benefit from the alliance.
Now two researchers from the Australian National University (ANU) School of Culture, History & Language, PhD candidate Phillip Parton and Professor Geoffrey Clark, have shown that this devastation of the population on Pacific islands was even worse than previously thought, with the population of the island of Tongatapu in the kingdom of Tonga being reduced to just 10,000 in 50 years, from 50-60,000 when Europeans first landed.
Their work, published in the Journal of Archaeological Science, indicates population declines were a lot larger than previously thought.

Creationism In Crisis - Another 'God-Filled' Gap Just Got a Lot Smaller
What is perhaps the favourite of all Creationism's 'God-filled' gaps - abiogenesis - just go a lot smaller with the news today that Nick Lane and colleagues of University College, London, UK, have shown how ATP became the universal energy currency used by all living organisms, so adding another layer to our understanding of how the earliest self-sufficient, self-replicating organisms arose from pre-existing molecules.
As always, the process evicts Creationism's shrinking little god because it is explained using just the natural laws of chemistry and physics acting on pre-existing molecules, with no place for magic or supernatural powers.
The mystery was, how the system for producing ATP could have evolved when the process used by cells today is a multi-step process which itself utilises ATP at six different points. Clearly, there must have been a simpler process for creating ATP early on in the evolution of living organisms and, because of it's universality, this was almost certainly in a common ancestor to all forms of life.
In prokaryote cells such as bacteria, the process occurs in the cell itself but in eukaryote cells the process takes place in the mitochondria - the descendants of bacteria originally incorporated into other prokaryote cells to give rise to the eukaryotes.
Creationism in Crisis - Evolutionary Palaeontologist, Svante Pääbo, Wins Nobel Prize for Medicine
This is the sort of news that the leading frauds in the Creationist cults must be dreading, if they still have an hope of convincing their dupes that the Theory of Evolution is a theory in crisis, about to be overthrown and replaced by religious superstition. It is the news that leading evolutionary palaeontologist and geneticist, Professor Svante Pääbo, director of the Max Planck Institute for Evolutionary Anthropology, Leipzig, Germany has been awarded a Nobel Prize for his work in the field of human evolution.
Far from being a theory in crisis, the Theory of Evolution is very much mainstream biomedical science, to the extent that the work Pääbo and his team are doing is central to our understanding of our recent history and how we relate to the archaic hominins that were our direct ancestors and the direct ancestors of other species of the Homo genus.
One of Pääbo's first major contributions to evolutionary biology was in sequencing Neanderthal genomes, then discovering that modern non-African Homo sapiens have at various times in recent history, had a significant ingression of Neanderthal DNA due to interbreeding between the two species. This horizontal gene transfer meant anatomically modern hominins acquired genes that had evolved in Neanderthals over a period of some 250,000 years, giving us significant adaptations to the cold, cloudy northern climates in Eurasia. Today, modern non-African humans have 2-4% Neanderthal DNA, most of it acquired about 40,000-60,000 years ago when the two species co-existed in Eurasia.
So What Did The Neanderthals Ever Do For Us?
More Evidence For a Human Ring Species
Evolution News - Women with Neanderthal Genes are More Fertile
Ancient Teeth Show Human Roots
There is also a mysterious fourth hominin whose DNA has been found in Neanderthals and some Homo sapiens. Neanderthals and Denisovans were the descendants of an earlier migration out of Africa of an archaic hominin, probably H. erectus. H. sapiens are almost certainly the descendants of those H. erectus who stayed in Africa.
What this tells us is that for much of recent human history, we have co-existed with several other hominin species whose evolutionary divergence from us and each other was not sufficiently advanced to prevent interbreeding, probably because for most of the 250,000 years that Neanderthals had lived in Eurasia, during which the ancestors of H. sapiens lived in Africa, interbreeding was a rare event so there was no evolutionary pressure to either reintegrate into a single species or to establish barriers to hybridization.
Having said that, though, there is a recent explanation for the disappearance of Neanderthals which suggests that they were never exterminated but simply merged into the growing population of H. sapiens which quickly outnumbered them, to the extent that there is now more Neanderthal DNA in the world than there ever was prior to 40,000 years ago. When Homo sapiens came out of Africa, the period of co-existence was too short for barriers to hybridization to evolve, so for much of our recent history, the Homo complex of species behaved very much like a ring species of incompletely speciated regionals species and subspecies.
Creationist frauds now have the task of explaining to their credulous dupes why, if the TOE is a theory in crisis, one of its main exponents, whose work only makes any sense in the context of evolving hominin species, has been awarded the most prestigious prize in science - a Nobel Prize. We can now expect a proliferation of childish conspiracy theories as they seek to cope with the cognitive dissonance.

Malevolent Designer News - How Creationism's Divine Malevolence Gives us Dementia
What is not generally recognised is the role of viruses, such as SARS-CoV-2 which caused COVID-19, have in causing dementia. Now recent research has shown that 'Long Covid' is emerging as one ot the most important causes of dementia.
Now, with many countries discontinuing the policy of isolating people with COVID-19 and allowing them to continue to work and mix socially, the virus is becoming endemic in the population, so the long-term effects, such as dementia are going to increase.
The following article by Professor John Donne Potter of the Research Centre for Hauora and Health, Massey University, New Zealand, reproduced from The Conversation under a Creative Commons open access licence, reformatted for stylistic consistency, highlights the role of viruses in dementia. The original article can be read here.
Viral infections including COVID are among the important causes of dementia – one more reason to consider vaccination

With more of us living into old age than at any other time, dementia is increasing steadily worldwide, with major individual, family, societal and economic consequences.
Treatment remains largely ineffective and aspects of the underlying pathophysiology are still unclear. But there is good evidence that neurodegenerative diseases – and their manifestation as dementia – are not an inevitable consequence of ageing.
Many causes of dementia, including viral infections, are preventable.
COVID and other viral infections are centrally involved in insults to the brain and subsequent neurodegeneration. COVID-positive outpatients have a more than three-fold higher risk of Alzheimer’s and more than two-fold higher risk of Parkinson’s disease.
A study of almost three million found risks of psychiatric disorders following COVID infection returned to baseline after one to two months. But other disorders, including “brain fog” and dementia, were still higher than among controls two years later.
🚨I wrote about “brain fog”—one of the most common & disabling symptoms of long COVID (and many other pre-pandemic conditions), and one of the most misunderstood.
— Ed Yong is on sabbatical (@edyong209) September 12, 2022
Here’s what brain fog actually is, and what it’s like to live with it. 1/ https://t.co/Gq8iylgfBr
More than 150,000 people with COVID and 11 million controls have been involved in a study of long-term consequences of acute COVID infection. A year after infection, there was an overall 40% higher risk (an additional 71 cases per 1000 people) of neurologic disorders, including memory problems (80% higher risk) and Alzheimer’s disease (two-fold higher risk). These risks were elevated even among those not hospitalised for acute COVID.
SARS-CoV-2, the virus that causes COVID, can invade brain tissue. Other viruses can also cause direct damage to the brain. A study of almost two million people showed the risk of Alzheimer’s was markedly lower in those who had been vaccinated against influenza.
The cost of dementia
Dementia is characterised by progressively deteriorating cognitive function. This involves memory, thinking, orientation, comprehension, language and judgement, often accompanied by changes in mood and emotional control.
It is one of the major causes of disability among older people. Worldwide prevalence exceeds 55 million and there are almost ten million new cases annually. It is the seventh leading cause of death. In 2019, the estimated global cost of dementia was US$1.3 trillion and rising.
The best known form of dementia – Alzheimer’s – was first described in 1907. Dementia is generally described as developing in three stages:
- impairment of memory, losing track of time and becoming lost in familiar places
- further deterioration of memory with forgetfulness of names and recent events, becoming confused at home, losing communication skills and personal care habits, repeated questioning, wandering
- increased difficulty walking, progressing to inactivity, marked memory loss, involving failure to recognise relatives and friends, disorientation in time and place, changes in behaviour, including lack of personal care and emergence of aggression.
There are no cures and no resounding treatment successes. Management involves support for patients and carers to optimise physical activity, stimulate memory and treat accompanying physical or mental illness.
Dementia has a disproportionate impact on women, who account for 65% of dementia deaths and provide 70% of carer hours.
We may know less about the pathology of dementia than we imagined: some key data are under scrutiny for possible inappropriate manipulation.
But we do know about many of the causes of dementia and therefore about prevention. In addition to viral infections, there are at least four other contributing causes: cardiovascular disease, type 2 diabetes (especially if untreated), traumatic brain injury and alcohol.
The brain has its own immune system – cells called microglia. These play a role in brain development, account for 5-10% of brain mass and become activated by damage and loss of function. They are also implicated in Alzheimer’s and their inflammation has been shown to be central to its pathology.
Dementia is preventable
In the absence of effective treatment, prevention is an important goal. The association with viral infections means we should pay careful attention to vaccine availability and uptake (for influenza, COVID and any future variants) and place greater emphasis on combatting misinformation regarding vaccines.
The association with atherosclerosis and stroke, as well as diabetes, supports primary prevention that involves healthier diets (plant-based diets low in salt and saturated fats), physical activity and weight control.
Alcohol consumption is a major problem globally. We have allowed high intake to be normalised and talk about no more than two glasses per day as though that is innocuous. Despite the myth of some beneficial aspects of alcohol, the safest intake is zero drinks per week.
My article speaks about a study that showed that people who chronically consume alcohol and become unconscious because of it, their chances of having dementia increase 10 fold. https://t.co/0DOFf9X5Zx @mrcopsych
— Hannah (@Hannah46221416) September 29, 2022
Traumatic brain injury is associated with sport and, more importantly, falls and car crashes. It is recognised as a global priority and there is increasing awareness of the preventability of falls among older people. The management of head injuries is being ramped up in contact sports.
However, data on the impact of best management of the initial injury on subsequent risk of dementia are lacking and risk remains elevated even 30 years after the initial trauma.
The evidence that dementia has preventable causes, including viral infection, should better inform policy and our own behaviour.

Malevolent Designer News - How Ticks Are Designed to Make Us Sick
Creationism's divine malevolence is nothing if not a fanatical perfectionist for whom no detail is too small in its quest to find ways to make its creation sick - or so you must believe if you've fallen for the intelligent [sic] design hoax.
Here for example is a paper in which the scientists have shown how well-designed ticks are for passing on infections to its victims, including humans and our livestock. The scientists found that tick saliva contains a powerful immuno-suppressant the prevent the body from reacting to the nasty little organisms it injects along with its saliva when it takes a meal. This also solves the mystery of why ticks are such powerful disease vectors. It almost seems they were designed for it.
The team of scientists led by led by Georg Stary (MedUni Vienna's Department of Dermatology, CeMM Research Center for Molecular Medicine of the Austrian Academy of Sciences, Ludwig Boltzmann Institute for Rare and Undiagnosed Diseases) in collaboration with the research group of Hannes Stockinger (Center for Pathophysiology, Infectiology and Immunology at MedUni Vienna) have published their paper, open access, in the Journal of Clinical Investigation.

Creationism in Crisis - How the Precursors of Paired Fins and Limbs Evolved
There is little doubt now that the paired terrestrial tetrapod limbs, possessed by all terrestrial vertebrates, and those such as whales and turtles that he reverted to a marine existence, evolved out of the paired pectoral and pelvic fins of fish that first crawled onto land. The remaining question was how did these paired limbs evolve in the early fish? Because of gaps in the fossil record, it had looked as though fins suddenly appeared fully formed.
That question has now been answered by an international team, led by Min Zhu of the Institute of Vertebrate Palaeontology and Palaeoanthropology, Beijing and Professor Philip Donoghue from the University of Bristol’s School of Earth Sciences, whose discovery shows the primitive condition of paired fins before they separated into pectoral and pelvic fins, the forerunner to arms and legs.
The evidence was found in fossils in the rocks of Hunan Province and Chongqing and named Tujiaaspis after the indigenous Tujia people who live in this region. Unlike previous fossils records which are mostly just the heads, these fossils contain the whole body.
Earlier fossils either had fins or they didn't, with no fossil record of transition to paired fins. That gap has now been filled by Tujiaaspis. There had been a hypothesis that fins probably began as folds but is was just that - a hypothesis awaiting confirmation or falsification. That confirmation has now been provided.

Creationism in Crisis - Scientists Have Reconstructed the Genome of the Earliest Mammalian ancestor

via Wikimedia Commons
The creationist delusion that the Theory of Evolution is a theory in crisis, about to be replaced in mainstream biology with their childish, evidence free superstition based on the ludicrous idea that nothing evolves and everything is made by magic, took another blow today when an international team of scientists led by scientists from the University of California Davis and the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW), Berlin, Germany, published their computed genome of the stem species from which all mammals evolved.
Such a project would not have been mooted had the scientists had the slightest doubt about evolution being the explanation for biodiversity, nor would it have been possible to compute this ancestral genome if the DNA of mammals did not form consistent hierarchy of nested clades resulting in evidence that the genomes of the ancestors of modern mammals form a family tree with a single origin, which lived about 200 million years ago.
The scientists' work is published in the scientific journal Proceedings of the National Academy of Sciences (PNAS).

Malevolent Designer News - Yet Another SARS-CoV-2 Variant and Another Wave of COVID-19 is On The Way
According to this article in Science, another wave of COVID-19 infections is on the way because several different sub-strains of the Omicron variant have converged on a similar way to evade the antibodies our immune systems manufacture in response to vaccination and/or infection.
It's not possible to say which of the various emerging strains will come to predominate, but one variant, known as BA.2.75.2, is a likely candidate. It is proving to be especially successful at evading antibodies because changes at half a dozen key sites in its genome that affect the way antibodies bind to the spike proteins on the viral coat, mean the antibodies don't bind very successfully.

Creationism in Crisis - Scientists Show How Large Molecules Self-Assemble - No Gods Required Again

The recent rum of bad news for Creationism just got worse, with the news that scientists from the University of Massachusetts Amherst have discovered how large molecules such as proteins and DNA can self-assemble with nothing more than the laws of chemistry and physics. As always when one of Creationism's favourite gaps is snapped shut by science, no gods were found and the 'mystery' required nothing more than the operation of the natural laws of chemistry and physics.
In the words of one of the researchers:
The significance of the discovery that dipoles drive the assembly of polymers is immense because it throws new light on one of the fundamental mysteries of life’s processes, [how biological materials know how to self-assemble into coherent, stable structures]. The theory changes the paradigm of how we think about these systems, and highlights the unacknowledged role that dipoles play in the self-assembly of biological materials.

Malevolent Designer News - The Asian Longhorned Ticks Are Spreading Fast in USA
News today of another stunning triumph for Creationism's malevolent designer!
The Asian longhorned tick, Haemaphysalis longicornis is spreading fast in the USA. Worldwide is causes millions of dollars in lost revenue for cattle farmers. It was first reported in New Jersey in 2017 and has now spread to Missouri. The tick is responsible for spreading the organisms that cause bovine theileriosis, which is similar to anaplasmosis in that it causes weight loss, reduced milk yield and death in cattle. The longhorned tick is closely related to other ticks in the Haemaphysalis genus which are found extensively in Asia and Australasia, all of which can and do transmit bacterial and viral diseases.
I described in The Malevolent Designer: Why Nature's God is not Good how another tick, the black-legged tick, Ixodes scapularis transmits the disease anaplasmosis in humans by injecting the rickettsia bacterium, Anaplasma phagocytophilum when it bites.

- Climate change, meaning the warmer temperatures in the US mid-west are creating a more conducive environment for it.
- the fact that females can breed parthenogenically, meaning they don't need to mate to produce thousands of fertile eggs - all of which are female with the same ability. This mean in a few years, a single female can quickly establish a very large population.
The University of Missouri news release explains the problem and how it was discovered:
Evolution News - How The Bird-Hipped Dinosaurs Evolved

First there was the news that plants have a ludicrously complex process for correcting the mistakes made when DNA is replicated, and how this shows common descent of plants and animals with the news that this process works when inserted into a human cell. Then there was yet more evidence of the malevolence of any creator who could come up with a design for a trypanosome flagellum that makes it easier for tsetse flies to inject it into us and cause sleeping sickness, and the news that a redesigned fungus is killing the frogs that would eat the mosquitoes that spread malaria. And lastly there is the news that the Theory of Evolution shows no signs of being abandoned as the best explanation for biodiversity but can even be applied to cultures with the finding that chimpanzees, like humans, form different cultural groups.
In fact, of course, most weeks are bad news weeks for Creationists because so many new scientific papers, especially in the fields of biology, archaeology and geology, refute Creationism without even trying, simply because, unlike Creationism, science is firmly grounded in observable and verifiable reality.
Now there is news that scientists from Cambridge University, UK, have shown how a group of dinosaurs, the remote ancestors of modern birds - the bird-hipped dinosaurs - evolved from a 'transitional', i.e., stem group, of dinosaurs, the silesaurs, which had been identified ten years earlier. They have published their finding in the Zoological Journal of the Linnean Society.

Malevolent Designer News - How Creationism's Divine Malevolence Made Tsetse Flies to Pass on Sleeping Sickness

This news item should please devotees of Creationism's putative intelligent [sic] designer, if for no other reason than that it involves a flagellum. Those who fell for Michael J Behe's opening ploy in his intelligent design hoax were fooled into believing that a flagellum is an irreducibly complex structure so must have been designed by an intelligent designer because it could not have evolved by Darwinian gradual evolution.
Of course, Behe ignored the fact that the component parts of the flagellar proton motor pre-existed the flagellum, in the Type II Secretion System, which was a development of the proton pump, so all that was needed was for them to be exapted for a different function, and to give the organism an advantage. It also ignores the fact that there are lots of different flagella found in nature, some with even fewer components than those of E. coli, which he had claimed was the minimum necessary for a functional flagellum. Clearly, if other flagella can work with less components, that of E. Coli is not irreducibly complex
And, unwittingly, Behe gave us the idea of a malevolent designer, because E. coli is much better at making us sick because it has a flagellum, than it would be without it. Given that Creationists believe their putative designer is omniscient, it must have been aware of that when it designed the flagellum.
Anyway, no matter how comprehensively the hoax is refuted, or how malevolent it makes their favourite god look, Creationists will ignore the science and stick with the refuted notion, so those are the people who should be thrilled by this discovery. It is the discovery that the trypanosomes carried by the tsetse fly, which causes sleeping sickness in humans and debilitating diseases in cattle and horses, has a flagellum specially designed to enable the tsetse fly to pass it on in its saliva when it takes a blood meal.
Origins of the English

Believed to have been commissioned by King Alfred the Great and inscribed "AELFRED MEC HEHT GEWYRCAN" (Alfred me had made) in the West Saxon dialect.
The answer might surprise those little Englander nationalists who took us out of the European Union, as well as those on the far right who foster daft notions of English racial purity, because even in the Early Middle Ages, the average English person was actually only about 40% Anglo-Saxon, and even that proportion of the 'English' genome came from continental regions bordering the North Sea, including the Netherlands, Germany and Denmark. 20%-40% came from what is today Belgium and France. The rest is derived mostly from the indigenous population that was present at the time of the Roman occupation - Brythonic Welsh. The evidence is that the Germanic immigrants sometimes integrated and intermarried in some area, while in other places they formed which might have been an elite upper class.

That fact is confirmed by the work done by the Max Planck Institute and University of Central Lancashire, scientists.

Cultural Evolution - In Chimpanzees

Archaeologist and primatologists from the Max Planck Institute for Evolutionary Anthropology, Leipzig, Germany, have discovered cultural differences between different groups of chimpanzees.
Ask any Creationist and they'll assure you that the fact that humans have developed art, music and architecture, to name just a few of our cultural developments, is evidence that there is something very special about humans, showing that we were specially created separate from the rest of 'creation' and given these 'gifts' to enable us to have 'dominion over the planet - which was provided for our benefit.
The problem with that argument from personal incredulity and wishful thinking, is that humans are far from being the only species to have cultures, albeit, our cultural developments of language and writing, combined with our ability to learn and recall facts, and to pass them on to our children, has enabled us to build on out innate ability to form cultural groups, to build advanced cultures. The difference is one of magnitude, not presence/absence. The analogy is with the elephant’s trunk, which is an example of variation on the same basic body plan, and so evidence of common ancestry, not special creation of elephants, although that analogy is probably too subtle for the simple binary thinking of Creationists.
The fact that our cultures have much in common with each other but vary considerably between different geographical groups is evidence of the evolutionary process involved in building those cultures. Sometimes, these cultural variations are very subtle, but most people who have been to other countries will be aware of them, especially with food, drink and language, and with little differences between driving behaviour, as I once showed with a blog post about the difference in driving customs between the UK and Naples, in Italy. What the scientists at the Max Planck Institute have discovered is that chimpanzees not only use stone tools as hammers to open nuts, but that the stone tool preferred varies between different social groups.
