Malevolent Design - How The Malaria Parasite is 'Designed' To Evolve And Outwit Medical Science


The malaria parasite generates genetic diversity using an evolutionary ‘copy-paste’ tactic | EMBL

Devotees of creationism’s divine malevolence would be conflicted by this news if they understood it, because it shows the creative genius of any intelligent designer who could come up with this system, but, it looks like it did so (if you believe it couldn't happen naturally) by setting up an evolutionary process that creationists are obliged by dogma to believe doesn't work.

The news is that the organisms that causes malaria, Plasmodium falciparum, is 'designed' to quickly find a way to overcome the anti-malarial drugs medical science has developed to cure people suffering from it and to prevent others from getting malaria, by evolving very quickly.

The discovery was by researchers at European Molecular Biology Laboratory's (EMBL’s) European Bioinformatics Institute who have identified a mechanism of ‘copy-paste’ genetics that increases the genetic diversity of the parasite at accelerated time scales. This helps solve a long-standing mystery regarding why the parasite displays hotspots of genetic diversity in an otherwise unremarkable genetic landscape. Copy-paste' is a way of doing something creationists insist is impossible without the aid of god-magic of increasing the genetic information in a genome and making it available for evolution by mutation and selection without any loss of function in the original copied genes.

The team have recently published their finding in the open access journal PLOS Biology and describe it in an EMBL news item:

Unintelligent Malevolence - Pathogens 'Designed' to Beat Medical Science In Two Different Ways

What makes a pathogen antibiotic-resistant? | Sanford Burnham Prebys

One of todays examples of the stupidity of creationism is something of a novelty. Usually, by applying the central tenets of creationism, any putative designer of living things like parasites either appears malevolent (and sometime it has to be said, malevolent at a near genius level in the ways it finds to make us and other animals sick) or it looks incompetent in that its 'solutions' are often to problems of its own making and more often than not to solutions it designed for one side of an arms race which it now trets as problems for the other side.

But today's example can only be described as an example of incompetent malevolennce, as creationism's putative designer, faced with the same 'problem' of medical science developing antibiotics effective against two different species of pathogen, set about designign two completely different 'solutions' to this problem. - Talk about re-inventing the wheel!

The pathogens are: Escherichia coli and Acinetobacter baumannii.

Creationists will probably be familiar with Escherichia coli (E. coli) because they believe their guru, Michael J Behe, 'proved' their god exists by claiming (falsely) that E. coli's flagellum must have been intelligently designed because he didn't know it evolved out of a pre-exiting structure and couldn't think how else it could have evolved. But then such is the standard of creationist apologetics!

What Behe had unwitting done was destroy the traditional excuse creationists use to explain pathogens like E. coli by blaming them on another 'designer' called 'Sin' which somehow creates living organisms although the creationit designer god is the only entitiy capable of designing livign things, so any example of 'intelligent design, real or imaginary, if 'proof' of this designer god's existance.

So, what creationists are now left with is an E.coli with a flegellum designed by their god to make it better at making us sick, and now resitant to antibiotics to help it win against medical science trying to prevent it makign us sick!

But what creationists are less likely to be familiar with is the pathogen, Acinetobacter baumannii, so here is a little background:

Malevolent Design - How a Bacterium Carries a Virus That Selectively Kills Male Insects And Only Allows Infected Females To Breed


How does a virus hijack insect sperm to control disease vectors and pests? | Penn State University

Wolbachia are a genus of bacteria that form a symbiotic relationship with about 50% of arthropod species, including insects and spiders but they can also manipulate the species for their own ends (in terms of breeding success). They are aided in this by a virus which is incorporated in their genome which has been shown to join forces with Wolbachia to ensure their own reproductive success in the form of females infected with the virus-bearing Wolbachia.

So completely have Wolbachia integrated with insects that one species of fruit fly has the entire Wolbachia genome incorporated into its own genome, making it, biologically, both bacterium and fruit fly.

One way Wolbachia ensure their own survival at the expense of the species of insect they infect is by making the sperm and egg incompatible if the female is not also a carrier of the right species of Wolbachia. And, to be on the safe side, two proteins produced by the virus break the sperm's DNA so any resulting embryo will be defective and will fail to develop. This ensures that only the females carrying the infection can breed, so increasing the Wolbachia and its virus in the gene pool.

The team who discovered this nasty little virus and how it acts selfishly, was co-led by Professor Seth R. Bordenstein, of the One Health Microbiome Center at Pennsylvania State University. They have published their findings in Science and described it in a Penn State News item.

But first, a little background on Wolbachia:

Malevolent Designer News - How Creationism's Divine Malevolence Is Adapting The Avian Flu Virus to Kill Marine Mammals


Avian Influenza Virus Is Adapting to Spread to Marine Mammals | UC Davis

As an example of creationist double-think and intellectual bankruptcy, their attitude toward parasites like viruses is a classic:
  • "Only God is capable of designing organisms, so "Look at the trees!" and "What about irreducible complexity?"
  • "Something else created parasites like bacteria, worms and viruses, because God wouldn't do something like that!"

Simultaneously committing blasphemy and refuting their own argument from teleology!

I wonder then how that rarest of animals, the intellectually honest creationist copes with the news that the creator of the avian flu virus, H5N1, is in the process of adapting it to kill marine mammals such as elephant seals, just as it adapted the SARS-CoV-2 virus from a bat virus to one that could kill humans and cause economic collapse.

Evidence that it is doing so, if you believe viruses are created and don't evolve naturally, which dogma forbids a creationist from believing, comes in the form of a study by scientists from University of California, Davis, and the National Institute of Agricultural Technology (INTA) in Argentina. The study, the first genomic characterization of H5N1 in marine wildlife on the Atlantic shore of South America, is published in the journal Emerging Infectious Diseases and is described in a UC Davis news release:

Malevolent Designer News - Creationism's Divine Malevolence Is Still Victimising Frogs

Scientists assemble a richer picture of the plight and resilience of the foothill yellow-legged frog | The Current

Almost unnoticed by the general public and noticed only by biologists and wildlife conservationists, is a pandemic far more deadly than the Covid-19 pandemic, or even the Medieval Black Death.

It kills a very high percentage of its victims, has already exterminated whole populations of frogs and other amphibians, and has contributed significantly to the global mass extinction currently underway.

It is, of course, the chytrid fungus Batrachochytrium dendrobatidis, which, along with a closely-related fungus, B. salamandrivorans, causes the fatal disease, chytridiomycosis, in frogs and other amphibians.

As an example of the work of creationism's divine malevolence, it takes some beating for its sheer malevolent nastiness. It infects the skin of these amphibians, through which they breath, and causes it to thicken and fail as a respiratory organ, leading to suffocation, multiple organ failure and death. Here is how I described it in my illustrated book, The Malevolent Designer: Why Nature's God is not Good:
Exterminating Frogs with a Fungus.

Most of the examples I’ve talked about so far have been organisms and viruses that affect humans, but we are far from being the only species that Creationism’s putative intelligent designer seems to have taken an intense dislike to. For example, the world’s frogs and other amphibians are currently being decimated by chytridiomycosis, caused by a couple of related Chytrid fungi, Batrachochytrium dendrobatidis and B. salamandrivorans. It has been estimated that over 500 different species have been severely reduced in number by this fungal plague, with over 90 extinctions.

These fungi seem to have originated in an area of Southeast Asia by modification of a common, harmless, soil fungus. In that part of the world, the local population of amphibians seems to be resistant to the pathogenic forms of the fungi, suggesting that these fungi frequently become pathogenic and the local population have built up resistance to it.

According to research carried out by a team from the Fenner School of Environment and Society, Australian National University, ACT, Australia, it was resistance in the local population which probably kept the disease from spreading more widely, until human agency intervened to change the environment. They have related the increased trade in amphibian species to the spread of the fungi all over the world where they found species with no evolved resistance (42).

Recently, another team found that one of the factors that could have made these fungi so successful is that the frog’s immune response seems to have worked against it. Researchers from the University of Central Florida and the Smithsonian Conservation Biology Institute (SCBI) found that, in the frog Rana yavapaiensis, a species known to vary in its ability to survive attack by these fungi, those which showed an elevated immune response had a worse outcome that those with a lower response (43). Somehow, the frog’s ‘designed’ immune system was working against it and the fungi had been ‘designed’ to exploit this.

ID advocates would have us believe that, for reasons unknown, their putative intelligent designer has deliberately redesigned a soil fungus so it can overcome the immune system it designed to protect frogs from infections, and so exterminate over 90 species of amphibians that it designed earlier and severely endanger some 500 species in what has been described as the biggest single loss of biodiversity, albeit, aided and abetted by humans in this endeavour. Creationism’s intelligent designer must really hate the frogs it designed. Maybe a private definition of the word ‘intelligent’ is being employed here.
Now a team of researchers from multiple American wildlife and conservation agencies have looked in detail at the spread of this fungus in one particular frog which has declined so rapidly it is now an endangered species - the foothill yellow-legged frog, Rana boylii. This small frog's range once extended from Oregon to Baja California.

They have shown that human agency is implicated in the spread of this fungus by not only spreading it around the world in trade, as the earlier Australian study found (42), but with regard to the foothill yellow-legged frog specifically, by global warming, climate change and habitat destruction as more land is converted to agriculture. They have published their work, open access, in Royal Society Open Science. It is also explained in a University of California Santa Barbara, news release:

Up to only a few inches in length, with a lemon-hued belly, the foothill yellow-legged frog may seem unassuming. But its range once stretched from central Oregon to Baja California. In 2023, it was listed under the federal Endangered Species Act. Its rapidly decreasing range is due in part to a fungal pathogen called Batrachochytrium dendrobatidis, or Bd, that has devastated amphibians around the world.

A team of researchers, including UC Santa Barbara’s Andrea Adams, has conducted the most comprehensive study to date of disease dynamics in foothill yellow-legged frogs. The team’s data — sourced from both wild frogs and specimens in museum collections — enabled them to track patterns of infection across a large geographic range. In a study published in Royal Society Open Science, the researchers reveal that drought, rising temperatures and the increasing conversion of land for agriculture appear to be the largest factors driving Bd infection in this species.

The researchers aimed to assemble as much data as they could, both in space and time. They surveyed in the creeks and rivers of California and Oregon, where they swabbed wild yellow-legged frogs for the presence of Bd. It also led them into fluorescent-lit museum collections to sample specimens from as far back as the 1890s.

The team leveraged a large network of people and institutions to amass this wealth of samples.

Many foothill yellow-legged frog field researchers had data that they weren’t actively analyzing, and so we were able to bring all of this data together and get it into a usable format that we could use to paint a much bigger picture of what is, and was, going on with Bd in this species.

The researchers swabbed each frog’s skin to determine if the animal was infected. To test for Bd, they used a PCR test, similar to some tests for COVID. By searching for Bd DNA from thousands of samples, the researchers were able to identify infection rates and severity. Co-lead author Ryan Peek ran this information through statistical models, which accounted for climatic, geographic, biologic and land use variables. This enabled the team to track disease patterns across a large geographic range over roughly 120 years.

The team discovered that disease patterns of Bd aligned with historical frog declines. The pathogen began to spread in the 1940s from the southern coast of California, moving northward and eventually affecting nearly the entire region. The biggest factors driving infection seem to be drought, increasing temperatures and the use of ever more land for agriculture.

Bd is a fungus that is spread through spores in the water, but that spread may occur differently in foothill yellow-legged frogs in different regions and climates, the researchers found. In some places, drought increased infection, while in others, it did not, possibly because of the presence or absence of other species that can carry Bd and share the same water, such as American bullfrogs, a species introduced from eastern North America.

If you combine the fact that there are bullfrogs building up the number of spores that these frogs are exposed to, and then they’re all kind of stuck in these small pools together, that explains why drought matters. They are suddenly getting hit with a really large number of spores and getting sick and dying.

These findings open more questions about what was stopping transmission and what allowed it to happen later.

What’s more, foothill yellow-legged frogs live exclusively in streams and rivers, not ponds and lakes. So the species is already stressed when these waterways shrink into isolated pools.

The progression of Bd in the foothill yellow-legged frog also differed from its course in other western amphibians. In many other species, the disease radiated from urban centers, rather than this clear south-to-north trend. What’s more, the disease showed up later in the foothill yellow-legged frog than in other species in its range.

Frogs switch from herbivores as tadpoles to carnivores as adults, which means they connect different nutrient cycles together in the food web. Their position at the center of the food chain also influences the ecosystem.

When you remove frogs from an ecosystem, what you get is less control of insects, things that the frogs would eat. There is also less food for things that eat the frogs, like snakes, birds and small mammals. It really throws things off and makes the ecosystem less stable and less functional.

“There are areas that have wet soils that would be alongside suitable habitat. In areas where more of those lands have been converted to agriculture, we see a higher risk of frogs being infected with the fungus.

The conversion of land for agriculture was another major factor influencing the spread of Bd. for these frogs.

In addition to disease hotspots, the team also identified a number of cold spots — areas where the pathogen is present but less influential. The existence of so many cold spots in different areas is a good sign, as it may mean that many areas have conditions suitable for keeping disease rates low, even as climate change increases temperatures and patterns of drought.

The authors are curious what might explain this clustering, especially when cold spots appear in unexpected locations: for example, places with similar habitat, land-use and climatic impacts as hotspots. It suggests there may be some genetic basis for the differences, whether on the pathogen side or the host side. Adams is currently researching the feasibility of reintroducing foothill yellow-legged frogs to Southern California.

The results of this paper shed a lot of light on the dynamics of where Bd occurs, what drives its spread and how the pathogen and frog may interact in the future.

We took a big snapshot of this species’ disease relationship through time. Earlier studies provided the researchers with glimpses into disease patterns in smaller geographic regions, “but now we have a much larger dataset that further confirms many of these patterns, and expands on them.

More detail is given in the team's open access paper in Royal Society Open Science:
Abstract

Species with extensive geographical ranges pose special challenges to assessing drivers of wildlife disease, necessitating collaborative and large-scale analyses. The imperilled foothill yellow-legged frog (Rana boylii) inhabits a wide geographical range and variable conditions in rivers of California and Oregon (USA), and is considered threatened by the pathogen Batrachochytrium dendrobatidis (Bd). To assess drivers of Bd infections over time and space, we compiled over 2000 datapoints from R. boylii museum specimens (collected 1897–2005) and field samples (2005–2021) spanning 9° of latitude. We observed a south-to-north spread of Bd detections beginning in the 1940s and increase in prevalence from the 1940s to 1970s, coinciding with extirpation from southern latitudes. We detected eight high-prevalence geographical clusters through time that span the species' geographical range. Field-sampled male R. boylii exhibited the highest prevalence, and juveniles sampled in autumn exhibited the highest loads. Bd infection risk was highest in lower elevation rain-dominated watersheds, and with cool temperatures and low stream-flow conditions at the end of the dry season. Through a holistic assessment of relationships between infection risk, geographical context and time, we identify the locations and time periods where Bd mitigation and monitoring will be critical for conservation of this imperilled species.

1. Introduction

Threatened species with large geographical ranges often require unique, regional conservation strategies to combat stressors such as infectious disease. Pathogen surveys and reporting have become standard for North American wildlife diseases [1,2]; however, relative risk across a landscape and among populations within species remains difficult to anticipate, especially when data are collected by separate research groups [3]. Central reporting databases [4], synthetic analyses and retrospective surveys can help assess disease threats and identify high-risk populations.

Among the most significant wildlife diseases, amphibian chytridiomycosis caused by the fungal pathogen Batrachochytrium dendrobatidis (Bd) has contributed to declines of hundreds of species worldwide [5]; but see [6]. In North America, notable Bd-associated declines have occurred across the west including the southern Rocky Mountains [7,8], Arizona and New Mexico [9,10], Nevada [11] and California [1214]. In several of these cases, infection outcomes varied widely among populations due to host-related and environmental factors including genetics, prior Bd exposure and abiotic conditions [1517].

For the stream-dwelling foothill yellow-legged frog, Rana boylii, Bd's role in the species' changing abundance across its endemic range (California and Oregon, USA) is not well-understood. The species has declined for at least the last half-century, with extirpations reported from xeric lower latitudes [18], at the wetter northern range limit [19] and downstream of large dams range-wide [20]. A mix of abiotic and biotic factors influence Bd infection risk and disease dynamics in many systems, including elevation, latitude, climate, habitat quality and host characteristics [21]. The relative importance of these factors remains unclear in rivers with winter flood/summer drought flow regimes typical across R. boylii's geographical range. Bd is considered a significant potential threat to R. boylii [22] because it is implicated in the species' disappearance from rivers of California's South Coast [23] and in recent autumn die-offs of R. boylii in Central Coast streams [24,25]. A large-scale assessment of Bd infections is needed to clarify how infections relate to historical declines in some regions' rivers and persistence in others, identify clusters of increased infection risk across the species’ range, and evaluate how infection incidence and severity changes with the seasonality of the Mediterranean climate and across the diverse ecoregions that R. boylii occupies.

Here, we leverage data from over 2000 field and museum samples covering 124 years to synthesize knowledge and evaluate patterns of Bd infections in R. boylii. We use a combination of modelling approaches and spatial scan statistics to ask: (i) how are Bd detections in R. boylii are distributed over space and time, (ii) whether watersheds with high versus low Bd infection risk clustered historically and today, and (iii) how Bd infections are related to biotic and abiotic factors. Our results highlight priority populations for Bd mitigation, regions that are data-deficient and warrant further sampling and monitoring, and remaining gaps in our knowledge about Bd susceptibility in R. boylii. Our study serves as a resource for wildlife managers implementing disease mitigation and species recovery projects, such as re-introductions, and as an example of collaborative research to address conservation challenges in wide-ranging imperilled species.

It must be thrilling for devotees of the putative divine malevolence to see the stunning success it is having exterminating so many species of frog, but one can't help but wonder what the ancestral frog did to incur this wrath. Did it maybe eat a forbidden mosquito or spawn out of wedlock?

The Unintelligent Designer: Refuting The Intelligent Design Hoax

ID is not a problem for science; rather science is a problem for ID. This book shows why. It exposes the fallacy of Intelligent Design by showing that, when examined in detail, biological systems are anything but intelligently designed. They show no signs of a plan and are quite ludicrously complex for whatever can be described as a purpose. The Intelligent Design movement relies on almost total ignorance of biological science and seemingly limitless credulity in its target marks. Its only real appeal appears to be to those who find science too difficult or too much trouble to learn yet want their opinions to be regarded as at least as important as those of scientists and experts in their fields.

The Malevolent Designer: Why Nature's God is Not Good

This book presents the reader with multiple examples of why, even if we accept Creationism's putative intelligent designer, any such entity can only be regarded as malevolent, designing ever-more ingenious ways to make life difficult for living things, including humans, for no other reason than the sheer pleasure of doing so. This putative creator has also given other creatures much better things like immune systems, eyesight and ability to regenerate limbs that it could have given to all its creation, including humans, but chose not to. This book will leave creationists with the dilemma of explaining why evolution by natural selection is the only plausible explanation for so many nasty little parasites that doesn't leave their creator looking like an ingenious, sadistic, misanthropic, malevolence finding ever more ways to increase pain and suffering in the world, and not the omnibenevolent, maximally good god that Creationists of all Abrahamic religions believe created everything. As with a previous book by this author, "The Unintelligent Designer: Refuting the Intelligent Design Hoax", this book comprehensively refutes any notion of intelligent design by anything resembling a loving, intelligent and maximally good god. Such evil could not exist in a universe created by such a god. Evil exists, therefore a maximally good, all-knowing, all-loving god does not.

Malevolent Designer News - How Creationism's Favourite Sadist May Use Climate Change To Increase The Suffering In The World


Parasitic worms cause huge economic loss to farmers and can infest humans too.
Temperature, humidity may drive future transmission of parasitic worm infections | Penn State University

Creationists who believe nothing happens unless their invisible magic god wants it to have to have all manner of intellectual gymnastics to avoid giving it credit for all the nasty things to be found in nature, such as parasitic worms.

Their favourite strategy is the old trick of believing two mutually exclusive ideas simultaneously - that only their god is capable of designing living systems, so anything too complex for them to understand must have been created by it, whilst simultaneously believing that all pathogens are created by another entity, called 'Sin', no matter how complex or difficult to understand they may be.

And of course, they are forbidden by dogma to believe in more than one creator and must believe, also by dogma, that that creator is omni-everything - omnibenevolent, omniscient and omnipotent - so they have to believe that whatever its designs do, they were designed to do it, and whatever the future may bring, they were aware of that whilst designing their creations.

What percentage of the surface of Earth is habitable to humans without special equipment? Approximately 29% of the Earth's surface is comprised of land, which is habitable to humans without special equipment. The remaining 71% is covered by water, primarily in the form of oceans, which generally require specialized equipment for prolonged habitation. Therefore, without considering other factors such as climate, terrain, and resources, roughly 29% of Earth's surface is habitable to humans without special equipment.
That means, creationists have no choice but to accept that the results of climate change were part of their designer creator's plan, as was the response of their creations to it. And one of those responses to climate change may be an increase in parasitic worms in parts of the world they have not been prevalent in before.

Many of these worms are, or have been, confined to the tropics and sub-tropical zones, and the northern and southern part of the world, where most advanced economies are based, have been relatively free from them. But, as Earth gets warmer, the 'habitable zone' for parasitic worms expands to incorporate more of the advanced economies, but the habitable zone for humans shrinks even further.

This is the prediction of a team of researchers from the Center for Infectious Disease Dynamics and Department of Biology, The Pennsylvania State University (PennState), Pennsylvania, USA, and Dipartimento di Elettronica, Informazione e Bioingegneria, Politecnico di Milano, Milano, Italy, led by Professor Isabella Cattadori and Dr. Chiara Vanalli of PennState, who have just published their findings, open access, in the journal Ecology Letters. Their work is explained in a PennState news release:

Malevolent Design - Another Arms Race Between A Parasitic Worm And Its Host - Or is It Just Unintelligent Design?


Cane Toad, Rhinella marina
A secret war between cane toads and parasitic lungworms is raging across Australia

The subject of parasitic arms races throws creationists into a bout of cognitive dissonance from which they can only emerge with a hefty dose of double-think and self-deception, telling themselves that it's perfectly logical to hold two diametrically opposite and mutually contradictory views simultaneously, like believing that the term 'circle' describes a spere but the term 'square doesn't describe a cube.

They need to believe that, whilst it is central to their dogma and the belief on which all their god of the gaps and false dichotomy fallacies relies - that there is only one creator god capable of whatever it is they are waving as 'proof' or its existence, and at the same time believing that parasites were created by a different creator, over whom their omnipotent god has no powers and who goes toe to toe with it in parasite-host arms races.

Sadly for creationists, they were denied the argument concerning a second creator by their guru and Deception Institute flunky, Michael J Behe, who used the evolution of parasites like Escherichia coli and Plasmodium falciparum (the malaria parasite) as 'proof that their god is the intelligent designer behind the 'design' of all living things.

So, let's do what Behe unwittingly did and remove the second, evil designer from the equation, and see where it leads.

A case in point is the recently discovered arms race between the Australian cane toads and the lung worm parasite that infests their lungs:

Unintelligent Design - How Scientists Are Overcoming The "Designer's" Incompetence


Systemic lupus erythematosus
World-first discovery may enable an effective long-term lupus treatment - Monash University

Readers may recall my recent article on Lupus and why women are nine times more likely to suffer from it than men, because the epigenetic process for switching off genes on their X-chromosome sometimes goes wrong and produces proteins that induce an immune response to their own tissues.

From a creationist perspective, this can only be for one of two reasons: either the designer was incompetent, or this was by design. The choice being either incompetence, or malevolence and misogyny.

Now a team of researchers at Monash University, Clayton, VIC, Australia, have reported success in finding a way to overcome this design defect - which begs the question: if scientists can do it, why couldn't an omnipotent intelligent designer? Could the answer be that the human immune system was not designed by an omnipotent, intelligent designer, but is the result of a mindless, utilitarian process that inevitably produces sub-optimal 'designs' that can't be scrapped and redesigned?

But that is the kind of thought that would cause panic in the mind of most creationists because it would raise the terrible spectre of wondering if they could be wrong.
The Australian team have just published their results, open access, in Nature Communications. They are also explained in a Monash University news release:

Unintelligent Design - How Scientists Are Learning to Do What Creationism's 'Intelligent' Designer Found Too Difficult - Or Didn't Want To Do!


The proteins needed to create limb progenitor cells are marked with different colors under a microscope.

The Surprisingly Simple Recipe for Starting to Grow a Limb | Harvard Medical School

Visit any site of a supposed Marian miracle, such as Lourdes, now selling 'miracle cures' that almost never work and those that do can be attributed to the medication the pilgrim was receiving prior to the visit, or to spontaneous regression, the placebo effect or a psychosomatic condition, and you may find lots of crutches supposedly left there as testament to the cure of mobility disorders, but what you will never find is the artificial limb discarded by someone who had a spontaneous regeneration of an amputated limb.

Or visit any of the lucrative travelling, carefully stage-managed 'faith healing circuses' where people appear to be 'cured' of all manner of ailments at the touch of a 'healer', who, for perhaps obvious reasons, never works in a hospital, and you will never witness the regeneration of a limb, or even part of a limb. Not even a finger or toe.

And before some-one cites, the 'Miracle of Calanda', this is such an obvious hoax that it's a miracle anyone believes it.

Despite having allegedly created a universe from nothing and all living things from dirt, creationism's god appears to be incapable, even with the help of his miracle-working mother, to be able to regrow a human limb.

The problem is one of the designer's own making (if you believe creationists) because it would involve the epigenetic resetting of the cells at the end of the stump, so they become stem cells again, capable of making all the different specialist cells in a limb, like bone, muscle, skin, nerves and blood vessels and growing to the right shape in the right place. That was a once-only ability in the developing embryo.

Epigenetics, as I have written about many times, is necessary because the cells of a multicellular organism replicate the same way our single-celled ancestors did - by replicating the entire genome every time in every daughter cell. But the benefit of multicellularity is that cells are specialised so only need a few genes, not the entire genome and having the wrong genes active in a specialist cell would be detrimental, so most of them need to be switched off by the epigenetic system. A problem which could have been avoided by any omniscient, omnipotent designer by just replicating those genes that were going to be needed by the specialist cells, but not something a mindless, natural process with no foresight, no reverse gear and no means of scrapping a bad design and starting again, could have avoided.

And yet medical scientists investigating the problem believe they have discovered the basic principles involved, which turn out to be "surprisingly simple", so well within the capabilities of even creationism's rather limited god.

The scientists, led by Harvard Medical School geneticists, have published their findings in an open access paper in a Cell Press journal, Developmental Cell and explain it in a Harvard Medical School news release by Stephanie Dutchen:

Malevolent Designer News - Creationism's Divine Malevolence Has Just Released An E. Coli Upgrade With Added Malice


New and highly infectiousE. coli strain resistant to powerful antibiotics - University of Birmingham

Escherichia coli is a pathogenic bacterium that is loved by creationists because they have been taken in by Michael J. Behe's book, Darwin's Black Box, that made him a millionaire because so many creationists bought it (though few appear to have read it) and which they love to wave around as 'proof' that the locally popular god exists.

Behe, a leading light in the Deception Institute, which was set up to try to win converts for fundamentalist, Bible literalist Christianity, by spreading disinformation about science, had argued, falsely, that the flagellum of E. coli must have been intelligently designed, since all the components need to be present for it to work (the 'irreducibly complex' fallacy) and it is too complex to have evolved in a single step because, so he claimed none of the components on their own could have given an advantage for natural selection to select for (which of course ignores genetic drift as a cause of evolution).

What Behe neglected to do was tell his readers that almost all the components of the flagellum and the proton pump that drives it, were present in a structure called the Type III Secretory system with which bacteria bind themselves to their host and kill them, and this could easily have evolved from simpler beginning over the billions of years that bacteria were evolving into their present forms.

Since its publication, Behe has been repeatedly told of the errors in it, and as a professional microbiologist, he should be aware of the growing body of research explaining how the E.coli flagellum evolved1,2, 3, 4, 5, yet he refused to correct his errors in later editions and continues to promote and defend the misinformation in it, whilst pocketing the royalties from sales, in a classic case of bearing false witness.

Malevolent Designer News - How To Keep Ahead In The COVID Game Against Creationism's Divine Malevolence - Keep Being Boosted


How long does immunity last after a COVID infection?

Creationists stuck with the evidence of parasites and viruses that appear to be designed for two purposes only - making more copies of themselves and increasing the suffering in the world by making us sick and die - traditionally try to ride two horses. They blame something else, like 'The Fall' or 'Sin' for them, whilst still arguing that their putative designer god is supreme in all things and the only entity capable of creating complex organisms.

They also get in a terrible muddle when asked whether their 'designer' god included an immune system to protect us from these parasites when it designed us before 'The Fall', in which case it was planning for it all along, or whether there was a subsequent upgrade to V.1.2, in which case it couldn't have been omniscient and had to redo its design to account for the unforeseen.

But whatever rationalisation creationists can think up for these mutually contradictory beliefs, we are left with the fact that viruses like the SARS-CoV-2 virus and our immune system are locked in an arms race, in which human medical science has had to get involved because the immune system isn't fit for purpose, and the protection it gives us is only temporary.

Meanwhile, medical scientists, aware of the fact that evolution by natural selection is going to continually produce new variants of the virus and that these viruses may become better at evading our defences, continue to apply that knowledge and develop new vaccines against the latest variants.

The following article by Lara Herrero, Research Leader in Virology and Infectious Disease, and Wesley Freppel, Research Fellow, Institute for Glycomics, both of Griffith University, Australia explains why regular vaccination with boosters to keep out immune system primed for the latest iteration of the arms race with a latest version of the virus.

Malevolent Designer News - How Bacterial Pathogens Are Cleverly Designed to Invade Their Victim's Body


Functional model for Yen-Tc toxicity. Following ingestion of the Tc, it is likely that the surface-bound chitinases bind to and/or degrade the chitin-rich peritrophic membrane of the insect midgut. Cell surface recognition is likely facilitated by motifs within the A subunits prior to internalization. Similarities to the well characterized bacterial binary toxin systems (e.g., anthrax, cholera, diphtheria) suggest a mechanism involving receptor-mediated endocytosis followed by pore formation and translocation of the B and/or C components into the cytosol (I), although alternative mechanisms (e.g., II, III) cannot be ruled out.

Imagine you're in charge of an invading army laying siege to your enemy's outer defences. How do you neutralise them?

One way would be to send a small group of soldiers, packed with high explosives and deadly toxins on a kamikaze mission into the defences, with instructions to detonate their explosives and so spread the toxins when inside to destroy the defences and kill the defenders. You could improve on that by removing any temptation the suicide bombers might have to not detonate their defences by automating the trigger to fire as soon as they encountered the defender.

That's exactly what a team at the Max Planck Institute for Molecular Physiology (MPI MOPH), Dortmund, Germany, have found bacteria use to gain access to their victim’s body and make their hosts sick and die. The team, led by Stefan Raunser, Director of MPI MOPH, have published their findings, open access, in Nature Microbiology. Their work is described in a MPI MOPH press release:

Bacterial meningitis damages one in three children for life | Karolinska Institutet Nyheter

Left untreated, bacterial meningitis is usually fatal, but even if it is treated with antibiotics and the patient recovers, creationism's divine sadist who designed the bacteria, ensures one in three of them will be lefts with varying degrees of disability, including mental impairment, blindness, deafness or loss of motor control that will be with them for life.

This is the conclusion of a new study published two days ago in JAMA Network Open. It was conducted by a team under the leadership of Federico Iovino, associate professor in Medical Microbiology at the Department of Neuroscience, Karolinska Institutet.

The team compiled data on 3,500 people who contracted bacterial meningitis as children between 1987 and 2021 and compared them to just over 32,000 matched controls from the general population. The average follow-up time was 23 years.

As the news release from the Karolinska Institutet explains:

Malevolent Design - No Fun For Creationists As The Candida Family of Fungi Are Evolving To Keep Infecting Us

Candida evolution disclosed: new insights into fungal infections | IRB Barcelona

The Candida genus of fungi are related to yeasts (i.e., single-celled fungi) but are specialists at living in or on our bodies and are common infections in body cavities such as the mouth, anus, vagina and urethra and the genito-urinary and respiratory tract, and other moist areas like armpits, inner surfaces of joints like the elbow and knee, groins and fold beneath breasts and buttocks.

They can also become systemic infections causing organ failure and death, especially in people who are immune compromised for any reason. So, they are a threat to people who are in generally poor health, who have had transplants and need to take immunosuppressive drugs, or people receiving chemotherapy for cancer.

And, like some bacterial pathogens, they are good at evolving immunity to anti-fungal medication.

One species, Candida auris, has evolved multiple drug resistance and is now a serious threat to people in hospital for other conditions.

Now, a research group from the Institute for Research in Biomedicine (IRB Barcelona) and the Barcelona Supercomputing Center - Centro Nacional de Supercomputación (BSC-CNS), led by the ICREA researcher Dr. Toni Gabaldón, has identified hundreds of genes subject to recent, clinically-relevant selection in six species of the fungal pathogen Candida. In other words, the genes that have given Candida species their clinically-relevant drug resistance.

First a little AI background to the Candida genus:

Unintelligent Design - Malevolence or Incompetence? - Why Design A Uterus To Grow Fibroids?

Researchers find ways that uterine fibroid cells respond differently from surrounding tissue | University of Cincinnati

Almost 80% of women of child-bearing age will develop uterine fibroids. Although usually not malignant, they can nevertheless be extremely painful, can cause bleeding and can lead to infertility. The economic cost of fibroids has been estimated to be some $9 billion in the USA alone.

Fibroids grow in response to the same hormones, oestragen and progesterone, which cause the endometrium to thicken then breakdown during the menstrual cycle. Now a research team at the University of Cincinnati have shown that cell stretching is also a factor in their growth.

Hormones and uterine stretching as the endometrium thicken and shrinks and during pregnancy and childbirth are, of course part of the normal state of affairs for the uterus that creationists believe must have been designed by their supposedly omniscience, omnipotent designer, so, if we accept that childish notion of magic design by an omniscient supernatural entity, for the sake of argument, we have to assume growing fibroids was all part of the plan, since it is not possible for an omniscient designer to not be aware of the outcome of its design and for it not to design with that outcome in mind.

So, the only alternative, within the creationist paradigm, is that fibroids are the accidental and unforeseen consequences of the design and function of the uterus - which would mean one of three things:
  1. The designer was not omniscient.
  2. The designer was incompetent.
  3. If the designer was both competent and omniscient it must have been malevolent and intended a high percentage of women to suffer the pain and inconvenience of fibroids.
This discovery is the subject of a research paper in the journal F&S Science which, sadly is behind a paywall, but the Abstract in the form of a summary of the paper is available.
