Evolution News - The Difference Between Information and Meaning

How a bacterium may help solve the plastic pollution crisis|NARA Institute of Science and Technology

One key concept in genetic evolution that Creationists, either wilfully, or because of genuinely limited critical thinking ability, find hard to grasp, is the difference between genetic information and the meaning of that information in the context of the prevailing environment. This makes them especially susceptible to professional frauds in the Deception Institute and others in the Creation Industry, to false claims about mutation always involving a loss of information, when what changes in most forms of mutation is simply a change in the meaning of the information.

Certain bacteria harbor the necessary enzymes to degrade PET, the most problematic plastic environmentally. Our research has shown that the bacterium Ideonella sakaiensis converts PET into poly(3-hydroxybutyrate) (PHB), a type of poly(hydroxyalkanoate) (PHA) plastic that is biodegradable.

We believe that this discovery could be significant in tackling plastic pollution, as we show that the PET-degradation and PHB-synthesis pathways are functionally linked in I. sakaiensis. This might provide a novel pathway where a single bacterial species breaks down difficult-to-recycle PET plastics and uses the products to make biodegradable PHA plastics.

This is illustrated neatly by the discovery that the 201-F6 strain of the bacterium Ideonella sakaiensis can not only degrade petroleum-based plastics but can also sustainably produce biodegradable plastics from otherwise non-biodegradable poly(ethylene terephthalate) (PET), a plastic widely used for disposable containers such as drinks bottles as well as textiles and food wrappers. This discovery was made by scientists at the Nara Institute of Science and Technology (NAIST), Kansai Science City, Japan. Their findings are published, open access, in Scientific Reports.

This ability depends on the presence of two enzymes, PET hydrolase (PETase) and mono(2-hydroxyethyl) terephthalic acid (MHET) hydrolase (MHETase) which together hydrolyse PET into terephthalic acid (TPA) and ethylene glycol (EG) monomers, both of which are readily biodegraded by other organisms.

In this strain of bacteria, genetic information has mutated to produce these two enzymes which, in the context of an environment highly polluted by man-made plastics, has given them the ability to exploit an abundant food source, unlike their ancestral form. Had this mutation arisen in pre-plastic times, it would have been utterly useless and might even have been detrimental in taking up resources to produce useless enzymes. In other words, the change in information now has a highly beneficial meaning in the context of a modern Earth, where once it had none.

In their paper published a few days ago in Scientific Reports the team say:
Abstract

Poly(ethylene terephthalate) (PET) is a widely used plastic in bottles and fibers; its waste products pollute the environment owing to its remarkable durability. Recently, Ideonella sakaiensis 201-F6 was isolated as a unique bacterium that can degrade and assimilate PET, thus paving the way for the bioremediation and bioconversion of PET waste. We found that this strain harbors a poly(hydroxyalkanoate) (PHA) synthesis gene cluster, which is highly homologous with that of Cupriavidus necator, an efficient PHA producer. Cells grown on PET accumulated intracellular PHA at high levels. Collectively, our findings in this study demonstrate that I. sakaiensis can mediate the direct conversion of non-biodegradable PET into environment-friendly plastic, providing a new approach for PET recycling.

What has changed in not the quantity of genetic information but the contextual meaning of it and that meaning has changed over time with the invention, use and environmental accumulation of vast quantities of non-biodegradable man-made plastic.

Civil war drove these elephants to lose their tusks—through evolution | Science | AAAS

Since evolution by natural selection is driven primarily by the selecting environment, rapid change in the environment can produce rapid evolution. If the selection pressure is strong enough, this intense selection can also result in a linked deleterious gene increasing in the population by being dragged up the fitness landscape by a strongly advantageous gene to which it is linked by close proximity on a chromosome.

This was the case in Mozambique, where during a 15-year-long civil war when there was intense poaching of elephants for their ivory to finance the armies of both sides and because any wild-life protection was largely absent or non-functional. In the Gorongosa National Park for example, the elephant population fell by 90% in 20 years with predation heavily selecting against those with tusks. Consequently, the gene for tusklessness in females increased in the population. Over a period of 28 years which included the 15 years of civil war, the proportion of tuskless females increased from 18.5% (n = 52) to 50.9% (n = 108), but so did the proportion of females in the population and the pre-term deaths of male calves!

This was due to an increase in the genes AMELX and MEP1a, which are associated in mammals with normal tooth formation. AMELX is linked by its proximity on the X chromosome to a dominant male-lethal syndrome in humans that also diminishes the growth of maxillary lateral incisors (homologous to elephant tusks). In other words, as AMELX increases in the population, so does a male-lethal gene that also reduces the growth of tusks in elephants. The result is an absolute increase in the proportion of live births of females and of tuskless females in particular.

In the abstract to their recent paper, a team led by Princeton scientists Shane C. Campbell-Staton of the Department of Ecology and Evolutionary Biology and Brian J. Arnold of Department of Computer Science, Princeton University, Princeton, NJ 08540, USA. said:
Abstract

Understanding the evolutionary consequences of wildlife exploitation is increasingly important as harvesting becomes more efficient. We examined the impacts of ivory poaching during the Mozambican Civil War (1977 to 1992) on the evolution of African savanna elephants (Loxodonta africana) in Gorongosa National Park. Poaching resulted in strong selection that favored tusklessness amid a rapid population decline. Survey data revealed tusk-inheritance patterns consistent with an X chromosome–linked dominant, male-lethal trait. Whole-genome scans implicated two candidate genes with known roles in mammalian tooth development (AMELX and MEP1a), including the formation of enamel, dentin, cementum, and the periodontium. One of these loci (AMELX) is associated with an X-linked dominant, male-lethal syndrome in humans that diminishes the growth of maxillary lateral incisors (homologous to elephant tusks). This study provides evidence for rapid, poaching-mediated selection for the loss of a prominent anatomical trait in a keystone species.
Over the short term, this attrition of males is not overly detrimental to elephants because herds are matriarchal with a single male able to serve multiple females and 'spare' males forming non-breeding 'batchelor' herds, so the population can remain stable or even increase with relatively few males.

What we can observe in this population then is a rapid evolution of a strong advantageous gene, in that tusklessness makes females less likely to be poached, with the 'opportunistic' increase in a deleterious gene which kills pre-term male calves by being linked physically to a strongly advantageous one, the deleterious effect in the population being more than compensated for by the overall advantageous effect.

Over the longer term, and with control of poaching, whatever environmental pressures led to the evolution of tusks in females originally is likely to reassert itself and the balance should shift back towards tusked females and more male live births. An beautiful example of how a changing environment changes the meaning of the same genetic information without any change in that information itself. And no magic deities involved anywhere in that process.

savanna chimpanzees, a model for the understanding of human evolution - Universitat de Barcelona

An international group of primatologists, co-directed by Adriana Hernández, of the University of Barcelona, Catalunya, Spain and Stacy Lindshield of Purdue University, West Lafayette, Indiana, USA, has studied the behaviour of savanna chimpanzees as a model for how the chimpanzee ancestors of hominids would have behaved at a key stage in their diversification from their common ancestor.

Although savanna chimpanzees (Pan troglodytes) are genetically identical to their forest-dwelling counterparts, they have several cultural differences that have enabled them to survive in a savanna environment which it hotter, drier and more seasonal than a forest environment. These are exactly the environmental challenges that early pre-hominid apes would have had to cope with in south and east Africa as climate change firstly isolated them in diminishing forests then stranded them in a relatively treeless landscape in which only those able to adapt would survive.

Like their modern counterparts, at least a substantial part of that adaptation was to evolve cultures which enabled them to adopt survival strategies. This in turn would then have facilitated the genetic changes which now distinguish us from our close cousins.
From the Barcelona University news release:
The study of chimpanzees in the savanna and what we call the effect of the savanna environment has important implications in reconstructing the behavior of the first humans who lived in similar habitats and therefore helps us to better understand our own evolution.

We know that early hominins adapted to savanna environments similar to those found by chimpanzees, and it is thought that savanna conditions caused adaptations in our ancestors, such as brain expansion or tolerance to high temperatures, therefore, understanding how our genetically closest relatives adapt to a dry, hot, seasonal and open environment, very similar to those where early hominins lived, helps us to analyze how our ancestors might have adapted and how the characteristics that define us as humans could have emerged.

Understanding how they cope with the heat can help us understand how the strategies that humans have to cope with the heat came about. Some are probably the same for chimpanzees and hominins, such as using caves or diving into water to cool off.

The early hominins also had to face water shortages for part of the year.

R. Adriana Hernández, Co-senior author

According to the researchers, the environmental conditions of these places would provoke a specific type of behaviors and physiological responses in these chimpanzees - such as resting in caves or digging to extract water - that do not occur in those of their congeners that live in wooded areas, where they do not they face such extreme environmental conditions.

[…]

The closest living genetically evolutionary relative to humans

Chimpanzees ( Pan troglodytes ) are the closest living evolutionary relatives of our species, sharing 98.7% of their DNA with humans and sharing an ancestor with them that lived approximately 4.5 to 6 million years ago. years. Despite this closeness, they lack some of the biological and cultural traits that humans possess to adapt to extreme heat, such as the numerous eccrine sweat glands, the relative lack of hair, or the ability to create artifacts such as containers of water. and sun hats that mitigate dehydration and heat stroke.

Chimpanzees that live in the savanna are taxonomically indistinguishable from other chimpanzees. For this reason, comparisons of behavior, morphology and ecology with those living in more forested landscapes provide key information for generating hypotheses or testing theories about how early humans were able to adapt millions of years ago as forests Africans were retreating and giving way to the savannas.

[…]

Strategies to adapt to high temperatures

Among the characteristics collected by the study, the strategies of savanna chimpanzees to tolerate high temperatures stand out… Another example that the researcher highlights are the ways in which these chimpanzees try to hydrate during the late dry season, such as digging for water when it is reduced to only a few points on the ground.

As well as adapting their behaviour to cope with high temperatures and seasonal water supplies, there is another adaptive cultural change. Instead of living in small bands occupying a relatively small, densely-populated territory where essential resources are in good supply, the savanna chimpanzees have had to expand their territory from the usual 3-30 km2 to about 100 km2 with a much lower population density. Larger territories are naturally harder to defend.

The group's findings are published, open access, in the journal Evolutionary Anthropology.
Abstract

Chimpanzees (Pan troglodytes) are the only great apes that inhabit hot, dry, and open savannas. We review the environmental pressures of savannas on chimpanzees, such as food and water scarcity, and the evidence for chimpanzees' behavioral responses to these landscapes. In our analysis, savannas were generally associated with low chimpanzee population densities and large home ranges. In addition, thermoregulatory behaviors that likely reduce hyperthermia risk, such as cave use, were frequently observed in the hottest and driest savanna landscapes. We hypothesize that such responses are evidence of a “savanna landscape effect” in chimpanzees and offer pathways for future research to understand its evolutionary processes and mechanisms. We conclude by discussing the significance of research on savanna chimpanzees to modeling the evolution of early hominin traits and informing conservation programs for these endangered apes.

Once again, we see biomedical scientists in no doubt that the difference between modern and ancient hominins, and how we diversified from our common ancestor with the modern chimpanzees, has an evolutionary explanation, with no hint whatsoever of a loss of confidence in the TOE to explain the processes involved in this transition that Creationists fantasise over. Consequently, we can observe bands of chimpanzees, subject to the same environmental forces that shaped our remote ancestors several million years ago and put hominins on the path that eventually led to Homo sapiens, and draw conclusions based on those observations. Also, what we can observer here is the beginnings of gene-meme co-evolution which has been a major factor in the evolution of modern humans.

Malevolent Designer News - Another Blow for Creationism

Bacteriophage caspids can carry extra DNA that the virus can tinker with.

Viruses are both the villains and heroes of life as we know it

Here is an article by Ivan Erill, associate professor of Biological Sciences, University of Maryland, in The Conversation, that would have those few intelligent [sic] design Creationists who have found the courage to read a scientific article punching the air with joy - until they read on and find it contradicts all they think they know about how their divine creative malevolence works.

The problem for these Creationists is, as I have repeatedly pointed out in this blog and in my popular, illustrated book, The Malevolent Designer: Why Nature's God is not Good, that whilst they continue to insist that only their putative designer god is capable of designing things like viruses and bacterial pathogens and bringing about change in its creations, they are portraying it as a pestilential, sadistic monster obsessively determined to make its creations suffer in ever more imaginative ways. A case in point being the SARS-CoV-2 virus that, at the time of writing, according to Johns Hopkins University has killed nearly 5 million people, made almost a quarter of a billion sick and is wrecking economies worldwide.

So, it will come as a relief to those Creationists who can understand this problem, that there is at least one scientist who can see a positive benefit in at least some viruses, particularly bacteriophage viruses or phages for short - until they discover that this benefit is in how it can help humans defend themselves against some of the nastier of their beloved malevolence's creations. To make matters worse for Creationists, the science, because it's written by a biologist, not a theologian who is mostly ignorant of this subject, is of course based on evolutionary biology, not Bronze Age superstition.

Evolution News - How Lizard's Teeth Fatally Bite Creationism

3D reconstruction of the skull of an Amazon racerunner (Ameiva ameiva) captured through an X-ray micro-CT scan. Complex teeth with multiple tips ("cusps") are visible on the jaws. This feature—also seen in the dentition of early mammals—evolved many times in independent lizard groups.

A couple of Creationist articles of faith have taken a beating with another biology paper that refutes them without even trying, as usual. This time it is the evidence of transition from simple to complex teeth in multiple lineages of lizard in response to the advantages that a vegetarian diet had over an insectivorous diet, and then the evidence that this evolution towards increasing complexity sometimes went into reverse.

This reversal is contrary to creationist dogma that says evolution always involve increasing complexity and new information and that any loss of information (and so loss of complexity) is invariably detrimental.

The paper is by a team of researchers from the Universities of Helsinki and Lyon and the Geological Survey of Finland, led by associate professor, Nicolas Di-Poï of the Institute of Biotechnology, University of Helsinki, and is published open access in Nature Communications.

Malevolent Designer News - How The Flesh-Eating Bug Was Created.

Vibrio vulnificus ("the flesh-eating bug")
Pictures of the damage it does are too distressing to show!
Clues Emerge: How Harmless Bacteria Go Rogue Turning into Deadly Flesh-eating Variants | University of Central Florida News

Creationist mode:


As any intelligent [sic] design creationist will tell you, nothing evolves, so all changes in a species are the result of direct, intentional design by their putative designer, who, depending on the particular creationist cult, is either the omnibenevolent god of the Bible, or the omnibenevolent god of the Qur'an. Either way, this putative creator only wants a maximally good world for its favourite creation - humans - to live in.

From COVID to V. vulnificus the emergence of human pathogens is one of the most concerning public health issues facing us but we know surprisingly very little about what triggers the change from harmless to deadly. We want to answer that question using aquatic pathogens such as the agent of cholera or V. vulnificus as model systems. Our study is a big step in understanding this emergence phenomenon, and will hopefully help us predict, prevent and manage future outbreaks.

Our results indicate how ecosystems may be generating pressures that facilitate the emergence of specific strains with pathogenic potential within a natural population. We now have evidence that the environment plays a most critical role in shaping the emergence of this pathogen. Nonetheless, we are pathogen hunters and there is much more research to conduct. But this is a critical starting point in solving the mystery of what are the elements/ingredients that make a pathogen?

Assistant professor Salvador Almagro-Moreno, Lead author
Burnett School of Biomedical Sciences,
College of Medicine,
University of Central Florida, Orlando, FL, USA
Curiously though, they also insist that the pathogens that make us sick and die are reputedly intelligently designed, making this creator god look like quite the opposite of an all-loving creator. Nevertheless, they will look at the results of this piece of research as evidence of the design ability of their god, and still insist that it can't be the result of a natural process in which no god(s) were involved.

The research in question was carried out by scientists from the University of Central Florida, led by assistant professor Salvador Almagro-Moreno, of the Burnett School of Biomedical Sciences, College of Medicine, University of Central Florida, Orlando, FL, USA. They investigated the difference between pathological and non-pathological strains of the bacterium, Vibrio vulnificus, found in the Indian River Lagoon in East Central Florida, where the organism is endemic. This bacterium can cause necrotizing fasciitis, so is also called the 'flesh-eating bug'. If ingested in oysters, for example, it can cause life-threatening septicaemia in patients with underlying health conditions such as diabetes mellitus. It is one of the fastest killing organisms with a mortality rate of over 50%.

The team investigated samples of organisms obtained from two different sites in the lagoon, one of which contains a population of potentially pathogenic V. vulnificus and the other a population of a non-pathogenic strain. They had previously identified a set of genetic markers that identify the pathogenic strain. They also examined the environmental factors that could account for the two distinct local populations - salinity, other bacterial communities in the environment, water pollutants, dissolved organic matter or the presence of algal blooms, etc.

Of course, being scientists, they were looking for environmental factors that could have driven the evolution of distinct local populations and produced pathogenic strains, but as any creationist will claim - this was all designed by their particular god, in full and omniscient knowledge of the effects it would have on its human victims.

Evolution News - What makes us Different to the Chimpanzees and Why it Should Bother Creationists

What makes us human? The answer may be found in overlooked DNA | Lund University.

Sometimes you just have to laugh at Creationists, the knots they have to tie themselves into to try to make their childish superstition match what real-world evidence shows.

This paper, for example, which argues that the functional genetic difference between humans and the chimpanzees is to be found, not so much in the 2% of the genes by which we differ from them, but in how the 'junk' DNA is used by the them and us.

Creationists, of course, hate the statistic about us sharing 98% of our DNA with chimpanzees, and the intelligent [sic] design cult hates the fact that so much of our DNA is junk and so evidence against design, intelligent or otherwise. They would normally be jubilant over a finding like this that shows at least some of it might make a functional difference, so is not strictly junk after all - until they realise that that function is all that separates us from the chimpanzees.

The open access paper in the on-line journal, Cell Stem Cell is by a team of scientists led by Johan Jakobsson, professor of neuroscience at the Wallenberg Neuroscience Center and Lund Stem Cell Center, Lund University, Sweden, together with colleagues from Washington University, USA and Ecole Polytechnique Fédérale de Lausanne, Switzerland.

How Michael P. Farris Tried to Block 2020 Election Outcome - The New York Times.

As students of Early 20th Century European history will be aware, the Christian churches were often amongst the most enthusiastic supporters of the extreme right-wing parties that overthrew democracy and installed odious, racist, misogynist and criminal fascist government in countries such as Portugal, Spain, Italy, Hungary and Germany. Not surprisingly then, they are amongst the most enthusiastic supporters of attempts by the extreme right-wing in the USA to overthrow democracy, reverse the stunning victory of the Democrats and reinstall the odious racist, misogynist and criminal Donald J. Trump in the Oval Office.

More evidence published recently that an archaic hominin spread far and wide out of Africa into Eurasia, many thousands of years before Homo sapiens migrated out of Africa.

This evidence is from the youngest Acheulean site so far discovered, at Singi Talav, in the Thar Desert, Rajasthan, India, dated to 177,000 years ago. This shows that stone tools were used there for over 1 million years and may have persisted until the arrival of H. sapiens. This stone tool-making technology is believed to have arisen in Africa about 1.5 million years ago and reached India, presumably by being taken there by migrants, about 1.2 million years ago.

This new dating was done by researchers led by Dr. James Blinkhorn of the Max Planck Institute for the Science of Human History. According to to their news release:

How Religion Keeps the Poor Poor.

Religious belief really does seem to draw the sting of poverty | The Economist

The problem with religion is that it teaches poor people to accept their 'place' in society and not to aspire to something better. This is the obvious conclusion to be drawn from a piece of research carried our recently by a group of sociologists and psychologists led by Jana B. Berkessel of the Mannheim Centre for European Social Research, University of Mannheim, Mannheim, Germany.

The team found that, contrary to accepted ideas, people with a low socioeconomic status (SES) in a developed country carry a higher psychological burden than their counterparts in developing countries. The assumption had been that the psychological burden would ease as society developed and became more prosperous. However the research showed that there was an inverse relationship between the psychological burden of SES and the religiosity of the society and there was a similar relationship between religiosity and economic development.

In other words, as society develops economically, so religiosity falls, removing the religious norms that ease the burden of low SES.

This conclusion came as a result of statistical analysis of three surveys covering 3.3 million people in 156 countries.

This teaching to accept your place is not confined to Christianity either but can be found in almost all major religions. The team say:
Among the religious norms that enable cultural groups to thrive is a set relevant for SES. That set eases the burden of lower SES (“The poor are admitted into Paradise before the rich, by five hundred years;” Vol. 5, Book 37, Hadith 4261, The Qur’an; “For those who are poor and destitute; May I turn into all things they could need;” Ch. 3, Verse 10, Bodhisattvacharyavatara) and it does so in part by casting a bad light on higher SES [“It is easier for a camel to go through the eye of a needle than for a rich man to enter the kingdom of God;” Matthew 19:24, The Bible, “The demoniac person thinks: So much wealth do I have today, and I will gain more;” Ch. 16, Verse 13, Bhagavad-Gita (16, 29)]
Their open access paper is published in PNAS:
Significance
According to a fundamental assumption in the social sciences, the burden of lower socioeconomic status (SES) is more severe in developing nations. In contrast to this assumption, recent research has shown that the burden of lower SES is less—not more—severe in developing nations. In three large-scale global data sets, we show that national religiosity can explain this puzzling finding. Developing nations are more religious, and most world religions uphold norms that, in part, function to ease the burden of lower SES and to cast a bad light on higher SES. In times of declining religiosity, this finding is a call to scientists and policymakers to monitor the increasingly harmful effects of lower SES and its far-reaching social consequences.

Abstract
Lower socioeconomic status (SES) harms psychological well-being, an effect responsible for widespread human suffering. This effect has long been assumed to weaken as nations develop economically. Recent evidence, however, has contradicted this fundamental assumption, finding instead that the psychological burden of lower SES is even greater in developed nations than in developing ones. That evidence has elicited consternation because it suggests that economic development is no cure for the psychological burden of lower SES. So, why is that burden greatest in developed nations? Here, we test whether national religiosity can explain this puzzle. National religiosity is particularly low in developed nations. Consequently, developed nations lack religious norms that may ease the burden of lower SES. Drawing on three different data sets of 1,567,204, 1,493,207, and 274,393 people across 156, 85, and 92 nations, we show that low levels of national religiosity can account for the greater burden of lower SES in developed nations. This finding suggests that, as national religiosity continues to decline, lower SES will become increasingly harmful for well-being—a societal change that is socially consequential and demands political attention.

It looks as though both Seneca and Napoleon were right in that religion is used by the ruling class to keep the poor happy and contented so they never aspire to anything better. The priesthoods are complicit in this deception in return for protection and special status within the state.

This much was evident in the repose of religions to a Pew Research forecast a few years ago that support for religions will grow in coming years as the populations of third-world and developing countries is set to increase. They were jubilant at the though that the number of poor people in the world was going to increase and that they would benefit from this growth, part of which, with their teachings against contraception and family planning and for female subservience, they were responsible for.

Here's some great news to thrill worshippers of Creationism's favourite malevolence, the putative designer god responsible for all living things and any changes they undergo over time.

Researchers at Hokkaido University, Japan, have identified a previously unknown, tick-borne virus, a type of orthonairovirus they have named Yezo virus. When infected from a tick bite, victims suffer from a fever, and a reduction in platelets (the circulating cell fragments responsible for blood-clotting following injury) and leucocytes (the blood cells responsible for infection control, etc) and abnormal liver function.

A couple of days ago I reported on the leaked report of the French independent commission of enquiry into child abuse by Catholic priest in France since 1950. The reports spoke of 10,000 victims of 3000 priests and other Catholic clerics.

The 10,000 figure was wrong and grossly underestimated the true number. In the report delivered to the Archbishop of Reims, Éric de Moulins-Beaufort, in his position as head of the French Conference of Bishops, which commissioned the report, the true number of abuse victims was estimated to be about 216,000 and possibly as high as 330,000!

Malevolent Designer News - Creationism's Divine Malevolence is Not Giving up on Covid-19

MU researchers identify mutations of Delta, Delta Plus variants // Show Me Mizzou // University of Missouri

Creationist mode:


There is one thing that Creationism's divine malevolence definitely is not, and that's a quitter.

Having designed one of the nastiest viruses to hit humanity for over a century, it is never going to let a little thing like human medical science stand in the way of killing millions of people, making tens of millions more sick and ruining national economies and private business all over the world, without a fight. Humans might think they are on the verge of defeating it with their vaccines, and natural antibodies but the intelligent [sic] designer still has a few tricks up its sleeve. They are not getting away with that.

So, it's busy looking for a variant that is not only more contagious than its first model, but can get around the antibodies the man-made vaccines produce, as well as the antibodies human immune systems produce naturally when infected. This is, of course, the same immune system that creationists believe their divine malevolence designed to protect us from the viruses and bacteria it designs to harm us, but that's by the by.

Birds' eye size offers clues to coevolutionary arms race between brood parasites, hosts | Illinois

The existence of arms races is about as good evidence as you can get that there is no intelligence behind life on Earth. After all, what single intelligent entity would indulge in an ultimately futile competition with itself where a solution to a problem is then turned around into another problem to be solved and so ad infinitum, in a futile, never-ending cycle of redesign for no ultimate purpose save possibly to make more parasites?

And this example of one such arms races is a good example. As so often with these arms races, it starts off with one species becoming an obligate parasite on another - and obligate parasites are themselves more evidence of the lack of intelligence since it will inevitably lead to yet another arms race as the parasitised species develops ways to resist or mitigate the parasite and the parasite has to counter those measures or become extinct. Any half-decent biologist will understand this, so it shouldn't be beyond the comprehension of an intelligent designer god.

And let's remind ourselves that Creationism's putative designer god is also normally the supposedly omniscient Abrahamic god of Christianity, Islam and Judaism who should therefore have foreseen that a pointless and ultimately futile arms race would ensue when it allegedly designed an obligate parasite.

How Trump's Team Concocted the Big Lie

Trump's lawyer, Rudi Giuliani
"Created the Dominion conspiracy lie out of whole cloth"
Rachel Maddow Reads Damning Giuliani Testimony Showing Roots Of Election Conspiracy | HuffPost UK

Trump's big lie team made a major tactical blunder when they falsely claimed that Dominion, who supplied voting machines, conspired to steal the election for Biden. What they failed to take into account was that Dominion would sue. The result of this is that it gives the Dominion legal team the right to discover the evidence on which the claim was based.

It turns out that not only was there no such evidence, but, questioned under oath, Trump's lawyer and former New York mayor, Rudolph "Rudi" Giuliani admitted he couldn't even remember where he saw the allegation that he went public with, or even where he was at the time or exactly when he heard them (court papers exhibit J-1, transcription pp 34-36), and that the claim of a witness was almost certainly made up. He thought he might have seen it on Facebook! But he wasn't even sure of that and anyway he was too busy to check!

In other words, the entire claim was an invention.

US Christians Targeted by Eastern European Troll Farms

Troll farms reached 140 million Americans a month on Facebook before 2020 election | MIT Technology Review

According to an internal Facebook report, leaked by a former employee to MIT Technology Review, in the run-up to the 2020 elections in the USA, Christians were amongst those specially targeted by Eastern European troll farms intent on interfering with the elections, to the extent that 19 of the 20 most popular Christian groups on Facebook were run by these troll farms.

The report found that, after the 2016 election, Facebook:

An Ancient Disaster | The UCSB Current

From the Middle East, archaeologists bring us evidence that, although a couple of Bible tales may have their origins in a real event which could have lingered in the folk memories of the ancient Canaanites, the truth was very different to the highly embroidered stories these memories were subsequently woven into.

The evidence is that the large Late Bronze age city, now known as Tall el-Hammam, in the Jordan Valley, north of the Dead Sea, was suddenly destroyed by the air-burst of a meteorite larger than that responsible for the Tanguska incident in Siberia in 1908, which was estimated to have been the equivalent of an explosion and heat-wave about 1000 times more powerful than the atom bomb that destroyed Hiroshima.

This explosion occurred in about 1650 BCE and, according to the authors of a paper published, open access, in Scientific Reports, could have been the origin of both the myths of Sodom and Gomorrah and the destruction of Jericho (identified as Tell es-Sultan, near to Tall el-Hammam) by an Israelite army led by Joshua.

For Bible literalists wishing to use this as evidence that the Bible is real history, these two mythological events allegedly occurred many years apart and not contemporaneously. The tale in Genesis of the destruction of the 'cities of the plain' and the survival of Lot and his daughters with whom he fathered two sons is, according to Israeli archaeologists, Finkelstein and Silberman, in The Bible Unearthed, probably a propaganda story written to discredit two rival Canaanite tribes to Israel, in Moab and Ammon, as the descendants of the children of drunken debauchery and incest. The story of the breaching of the (non-existent) walls of Jericho and its sack by Joshua's mob came much later, in Joshua, at the end of the supposed exodus from Egypt and the mythical entry into the 'Promised Land' by the Israelites.

Atheist News - How Atheists Don't Need a God to be Good, But Theists Need One to be Bad.

Misinformation and Facts about Secularism and Religion | Psychology Today

In this devastating rebuttal of the 2011 claim by Dr Thomas G. Plante, Ph.D, that generally, religious people are more moral than non-religious people, David Niose, former president of both the American Humanist Association and the Secular Coalition for America, points out the factual and unfounded errors in Plante's article. In particular:
Plante casually claims that religious people are "better citizens" and "behave better." And without citing any sources, he tells us: "Research has consistently found that religious people are less likely to engage in criminal behavior, marital infidelity, alcoholism, unprotected sexual activity. . ." In other words, according to Plante, if you're not religious you might be a good person, but on average you are more likely to have these undesirable characteristics. This is a bold assertion that, of course, immediately puts secular individuals on the defensive. (Just imagine if the same claims were made against any other minority group.) It is precisely claims like these that lead to many Americans having an unfavorable view of atheists and other nonbelievers. Fortunately for atheists, agnostics, and secular humanists, there is no factual basis for Plante's claim that "research has consistently found" secular individuals to be more prone to such antisocial behavior.

Christian Hate News - Loony Talibangelical Extremist Greg Locke on the War-Path.

Pastor Greg Locke, Global Vision Bible Church, Tennessee.
"This means war!"
Hate-Preacher Tells Right-Wing Crowd They’re Being Persecuted: “This Means War!” | Hemant Mehta | Friendly Atheist | Patheos

Readers of this blog will be very familiar with false prophet, rabid homophobe and preacher of hate with a persecution complex, Greg Locke, who recently announced he was building the violent Church that Jesus wanted. An announcement that promptly got him banned from Twitter and resulted in several of his more offensive YouTube videos being taken down.

According to Locke, only gay people would do nothing while the evil, Satanic Democrats closed churches to stop them spreading the coronavirus, and Jesus wasn't gay so he would have defended his First Amendments rights with his Second Amendment rights.

It goes without saying that the US Constitution applied in 1st Century Palestine and Jesus jealously guarded his right to use guns to keep his churches open by posting armed thugs at the door to stop the authorities "trying something"!

I'm not a psychiatrist, but Locke's behaviour since he was shown to be a false prophet by falsely prophesying that Trump would win last November by a landslide because God had told him personally, he would arrange it, is becoming so bizarre and extreme that if his behaviour doesn't meet the definition of insanity, then insanity needs to be redefined.

Creationism's Favourite Felon is Back Behind Bars.

Mr Kent Hovind. Back in prison, this time for assaulting his ex-girlfriend.
Creationist Kent Hovind Sentenced to 30 Days in Jail for Domestic Violence | Hemant Mehta | Friendly Atheist | Patheos

Creationism's favourite criminal, Mr Kent Hovind, is back in prison. Let's try to help him be a better person.

To anyone familiar with Hovind's distain for the law of the land, believing he makes his own laws because he has a close personal relationship with God, this will come as no surprise, since Hovind pushes a relentlessly literal interpretation of the Bible and the Bible positively commands behaviour which might have been acceptable in a brutal, Late Bronze/Early Iron Age tribal society but which is, following the European Enlightenment and the incorporation of Humanism into Christianity, now regarded as criminal in most civilised societies.

Covidiot News - The Sad Self-inflicted Genocide of Anti-Vaxx Covidiots Continues

Anti-vaxx couple dies of virus after claiming they survived pandemic despite being unvaccinated - Alternet.org

If there is one thing that should feature 'bigly' in history's assessment of Donald Trump's legacy, it is the huge number of covidiot deaths of those who listened to him and his allies in the Talibangelical Christian cults, the QAnon conspiracists and the Repugnican politicians who prefer to allow this self-inflicted genocide to proceed rather than lose face and admit they were wrong about the pandemic, the measures to control it and then the efficacy and safety of the vaccines.

Here for example, is yet another case of two people who believed the anti-vaxxer fools and not the experts. They are, or rather were, Dusty and Tristan Graham, who styled themselves the "Alabama Pickers", popular YouTube/eBay resellers. According to their daughter, Windsor Graham, Dusty died of COVID-19 last Thursday after a three-week battle against the virus while Tristan died suddenly on August 20th from COVID-19-related complications.

Jews and Arabs Descended from Canaanites - Biblical Archaeology Society

Jews and Arabs Descended from Canaanites - Biblical Archaeology Society

In their book, The Bible Unearthed: Archaeology's New Vision of Ancient Israel and the Origin of Sacred Texts, Tel Aviv University archaeologists, Israel Finkelstein and Neil Asher Silberman conclude from the archaeological evidence that the history of the Jews in the Old Testament, including that in Exodus, is almost entirely invented; the Jews arose in situ from indigenous Canaanites, carving out the states of Israel and Judah on land peripheral to the Bronze Age Canaanite city states as these faded during the Early Iron Age.

The invented history simply reflects the rivalry between these closely related populations and, as with all invented histories, shows those writing them to be the superior group, having stunning victory after stunning victory over their rivals, whom they always totally vanquished and annihilated and enslaved, and having the superior tribal god(s). The stories were invented to give retrospective justification for genocide and land-theft and invariably exaggerated them, as we can see from the fact that there are descendants today of these supposedly totally annihilated tribes.

Malevolent Designer News - How a Bacterium Turns Plants Into Zombies

Lime witches broom, induced by Phytoplasma
The microbial molecule that turns plants into zombies | John Innes Centre

Parasites that turn their hosts into zombies that serve only the needs of the parasite, are by no means uncommon in nature. In fact, I include several examples in my popular, illustrated book, The Malevolent Designer: Why Nature's God is not Good. To the perpetual embarrassment of Creationists who like to pretend that their putative designer god is one and the same as the supposed god of love in the Christian Bible, they betray the fiendishly evil, amoral mind of anything that could have consciously and intentionally designed such relationships.

And now we have one more to add to the long, sorry list.

Atheists Top the List of Those Doing Right by Others. Evangelicals are Bottom.

Atheists nab top spot in shots; White evangelicals least vaccinated - Freedom From Religion Foundation

I mentioned at the end my last blog post that Christians seem to need the promise of a reward in order to do the right thing, with the implication that it would be much better if they just did the right thing because it is the right thing to do. However, nowhere in their handbook of morals and ethics, is that ever mandated or even recommended.

The closest they come to it is the instruction to do to others what they would want others to do to them - the so-called golden rule, common to just about every culture. Unfortunately, after several decades of the Republicans advocating greed and selfishness and insisting that it deserves a reward, most American fundamentalist Christians have come to associate doing the right thing by others as some sort of undesirable, socialist/liberal subversion of the 'American Way', and so not what God wants at all.

Few things highlight this better than the findings of a recent Pew Research survey into COVID-19 vaccine take-up, which places white evangelicals at the bottom of the table and Atheists at the top. Atheists clearly understand that by being vaccinated, they are not only protecting themselves, but also protecting other people and the society at large, by:

Covidiot News - The self-inflicted Genocide is not Confined to American Fundamentalists...

Hai Shaulian, leading Israeli anti-vaxxer, died of COVID-19, last Monday morning
Anti-Vaccine Activist Who Said 'There's No Epidemic' Dies of COVID

Evidence that the self-inflicted genocide which is currently culling the herd by removing right-wing fundamentalist anti-vaxxer covidiots, is not confined to America, but includes Israeli anti-vaxxers too, comes with the death from COVID-19 of the anti-vaxxer activist, Hai Shaulian in an Israeli hospital.

Sadly, neither prayer, nor his assertion that the 'Creator of the World' was with him so he had nothing to fear, made any difference, and despite the efforts of the hospital staff using medical science, he died last Monday morning. Another life sacrificed on the altar of conspiracy theorists' egos.

Unintelligent Designer News - Muddling Through Without a Plan and No Idea About Good Design

Some caterpillars have a surprising ally for when attacked by an endoparasitic wasp.
Horizontally transmitted parasitoid killing factor shapes insect defense to parasitoids

You know, for a supposedly intelligent designer, Creationism's putative designer god, who designed everything in full and perfect knowledge of what it would do, comes up with some monumentally stupid designs. At times, it's almost exactly like it doesn't have a plan at all and has no idea what it is trying to achieve - other than a creation with as much suffering in it as possible, with no opportunity to make something sick ever ignored.

Here, for instance, is yet another example of how it designed something, then treated that design as a problem to be solved with another design, only to then design a way around that solution to the problem it designed earlier. It is, of course, another example of that major embarrassment to intelligent [sic] design creationists, parasitism and the inevitable evolutionary arms race.

The arms race in this case it that between moths and parasitoid wasps that lays their eggs in the living body of the moth larvae, or caterpillars. Creationists would, of course, assert that their divine malevolence designed the wasps to parasitise the caterpillars because it is the only intelligence capable of designing such a thing as a parasitoid wasp and its method of reproduction (although they never explain the exact method by which intelligence makes chemistry and physics do something they couldn't do without it, nor do they ever provided evidence that this has ever been observed to happen, seemingly preferring conjectures and mysteries to answers, whilst still pretending to be scientists).

Now, a group of researchers from the Tokyo University of Agriculture and Technology, Fuchu, Japan and the University of Saskatchewan Department of Biology, Saskatoon, Canada, have discovered that a virus carried by some caterpillars is lethal to the grubs of these parasitic wasps. Not only that, but some caterpillars are capable of manufacturing the toxic protein, or 'parasitoid killing factor' (PKF) themselves, without the virus. These moths have incorporated the genome of the virus into their own genome and now just use the portion of it that codes for the parasitoid-killing toxin.

Another Creationist Falsehood Exposed - A Beneficial Mutation Helped Early Pastoralists Expand Their Range

Milk Enabled Massive Steppe Migration | Max Planck Institute for the Science of Human History

The problem with Creationist child-like black vs white thinking is that their assertions are usually very easy to refute, although that rarely, if ever, results in a change of mind. One easily debunkable claim, for example, is that all mutations are harmful.

This demonstrable falsehood forms the basis of Michael J. Behe's recent attempt to replace his failed intelligent [sic] design hoax with his 'devolution' nonsense, in which he tries to argue that, although mutations arise and are inherited, just like the TOE says, but, because they are always harmful, this is 'devolution' not evolution and so is a degeneration from the initial perfection of creation, consistent (of course) with the Bible narrative
a–c, Eneolithic (a), Early Bronze Age (b) and Middle–Late Bronze Age (c) sites in the Pontic–Caspian region, showing the number of individuals with a positive dairy identification out of the total number of individuals with preserved ancient proteins for each site. Strong evidence of preservation of equine or ruminant milk protein identifiers are depicted with black animal icons; the single individual with equivocally identified casein peptides is shown with a grey icon. For a map of all sites (including those without preserved proteins), see Supplementary Fig. 1. Base maps were created using QGIS 3.12 (https://qgis.org/en/site/), and use Natural Earth vector map data from https://www.naturalearthdata.com/downloads/. The horse image is reproduced from ref., 33; sheep silhouette, public domain (https://thenounproject.com/icon/12538/).
of 'The Fall'. Needless to say, Behe is silent on the problem of how to explain a harmful mutation increasing in the species gene pool.

Behe's problem, however, is that this is very easily debunked with real examples, although that never troubles devoted Creationists who will either be blissfully and diligently unaware of the real examples, or will have one or more strategies for dismissing them.

Here though, is one which will be difficult to ignore because it is still present in descendants today and they are very probably enjoying its benefits. It can't possibly be dismissed as harmful because it is so manifestly beneficial and even central to so much of Western food culture. I'm talking about the mutations which caused lactase persistence, which was regarded as so 'normal' that its absence, which causes lactose intolerance was regarded as the abnormal trait, causing what was regarded as a dietary disorder in those without the mutation.

Talibangelical Hate News - Trumpanzee Loon, Pastor Greg Locke, Banned from Twitter

After Twitter Ban, Christian Hate-Preacher Greg Locke Whines About “Persecution” | Hemant Mehta | Friendly Atheist | Patheos

I'm not sure if this is good news or bad news. Pastor Greg Locke, of Global Vision Bible Church, Tennessee, is such a goldmine of anti-fundamentalist propaganda that it'll be a shame to lose him, but on the other hand, events have shown that there are people, especially in USA, who are gullible enough to let him think for them. Given his increasing advocacy of violence, repeated misinformation about Trump's defeat last November, which he still can't bring himself to accept, and his Trumpanzee/QAnon-inspired anti Covid vaccine lies, he constitutes the sort of danger to society that Twitter should be protecting its customers from.

In fact, the true value of preachers of hate like Locke is that they server to remind us what a violent and hate-filled religion Christianity would be if it hadn't been moderated and civilised by a hefty dose of Humanism following the European Enlightenment. They simply preach a pure version of primitive Medieval Christianity, based on Bronze Age, despotic Middle Eastern tribalism of which the Taliban and the Spanish Inquisition would be proud.
