Unintelligent Design - Rejuvenating Parasites

Schistosoma mansoni

Stem cell progeny contribute to the schistosome host-parasite interface | eLife

It gets a bit tedious to keep writing about all these examples of mindless stupidity in biological 'design' but my creationist readers love having something to ignore, or in some cases, post abusive comments on to impress Jesus.

So, not wishing to disappoint, here's another one. It is the discovery, published today in eLife, that a particularly nasty flatworm parasite, Schistosoma mansoni, that causes schistosomiasis in tropical parts of the world, has a simple defense to the human immune system that is trying to destroy them.

My Intelligent (sic) Design believing friends tell me that everything in nature was made by magic by the same magic man they believe also wrote the Bible so they believe this Intelligent (sic) Designer made these parasites especially so they could live in our blood and make us sick. The problem is, it then seems to have

Snappy End to Creationism!

I don't suppose the discovery of a 320 million year-old fossil of a giant crocodile is going to change many creationists' minds about Earth being around 6,000 years old but then nothing ever seems to. Evidence is such a difficult thing when it doesn't tell you what you want to believe - unless you're honest, like normal people.

This particular new example of how creationists need to go to quite idiotic lengths to retain their childish superstition was found by paleontologists from North Carolina University led by Lindsay Zanno, and practically on their doorstep in the Triassic Carnian Pekin Formation. The authors have named this long-legged, bipedal crocodile, the Carolina butcher (Carnufex carolinensis). With its long snout, large mouth, long legs and probable speed, it would have been a menacing beast. C. carolinensis would have been about 9 feet (3 metres) long and about 5 feet (1.6 metres) tall with blade-like teeth.

Even Fish Walk All Over Creationists

How creationists love those gaps!

Real or imaginary, you'll find creationism's magic creator stuffed into as many gaps as they can find to stuff it into. Until, that is, science actually looks at the gap. At that point there is always one of two outcomes:

1. The magic creator isn't there and the gap is full of perfectly natural, scientifically understandable stuff.
2. The gap wasn't there in the first place. It was either made up, the product of creationist wishful thinking, or, rarely, due to a scientific mistake.

USA Religious Decline Confirmed

Is the United States a Counterexample to the Secularization Thesis?: American Journal of Sociology: Vol 121, No 5

According to data produced in the American Journal of Sociology, the USA should no longer be regarded as an outlier when it comes to religiosity, compared to the rest of the Western, developed world.

Although the movement has been small compared to Europe, there are distinct signs that Americans are moving in the same direction and for pretty much the same reason - each generation is becoming less religious.

Reassessing Those Rattlers | Research Frontiers.

One of the indispensable dogmas of creationism in its desperate attempt to fool people into thinking the Theory of Evolution is fatally flawed is that 'microevolution' and 'macroevolution' are different things needing different processes to explain them. 'Microevolution' is supposedly the evolution of variation, varieties, races, subspecies etc, while 'macroevolution' is supposedly the evolution of a new species.

Misleading Christians

On Darwin Day, 5 facts about the evolution debate | Pew Research Center

Although all but the most honest creationists will try to pretend that their unscientific, anti-science views are actually good science with masses of scientific support, because that is the impression that the fraudsters who misinform them give them, the evidence from a Pew Research Center study into the views of Americans on evolution, re-published on Darwin Day this year, shows something completely different.

It shows that these unfortunate people are getting their 'science' not from proper scientists but from preachers and pastors who normally have no training in science whatsoever and that their opinions are based on religious dogma, not a rational examination of the scientific evidence. There is a clear correlation too between the degree of fundamentalism in religious affiliation with the degree of rejection of the scientific view of evolution by an unguided, natural process.

Jehovah's Witness (6%), Mormons (11%), Evangelical Protestants (11%) and 'Historically Black' Protestants (16%) all report astonishingly low (by European standards) levels of understanding that humans are the result of evolution by a natural process. This figure only rises to 28% for Mainline Protestants, 29% for Orthodox Christians and 31% for Catholics, still low by European standards.

The mainstream Christian figure is close to that for Muslims at 25%. It may surprise many fundamentalist Christians to discover that they are more extreme in their views than Muslims, who they traditionally regard as extremists.

Rarely do I venture into American politics in these blog posts, but the increasingly right-wing political extremism of the Republican Party, as it cements its ties with Christian fundamentalism, becoming, in effect, the political wing of the Christian theocratic and anti-science movement, is worth commenting upon.

First a little test.

Supposing, just for the moment, that Jesus were to return, and was pretty much the way he is portrayed today in his social attitudes, given the following choices, which would he be most likely to go for?

• Would he:
  
  1. favour giving even more money to the rich?
  2. favour giving money to the poor?
• Would he:
  
  1. favour leaving the sick to fend for themselves as best they can?
  2. favour helping the sick to get better, regardless of their income?
• Would he:
  
  1. favour sending more people to prison for longer?

For those wingnuts who still believe in intelligent design, the hardest thing to explain, if they ever give much thought to it, is why their putative intelligent (sic) designer so often resembles a malevolent, hate-filled and completely evil designer who hates everything it has designed.

The story goes that this intelligent (sic) designer created the entire Universe just so it could make a tiny planet in a remote part of it (bear with me! I'm not making this up!) so it could make intelligent beings to worship it. So thrilled was it with it's invention, which it had taken an infinite amount of time to think up, that it loves it more than anything.

Any gap will do, and if the right one can't be found, one can easily be invented with a childish parody of science. No-one will ever notice because the target audience couldn't tell a childish parody of science from the real thing. It's all magic anyway.

Vatican Issues Abuse Cover-Up Code - Omerta!

Catholic bishops not obliged to report clerical child abuse, Vatican says | World news | The Guardian

This report from last week slipped under my radar unnoticed.

The Vatican has issued new training material for newly-named bishops which tells them they don't have any obligation to report cases of clerical abuse of children unless the local law requires it. Their only obligation is to deal with the matter internally. Apparently, the notion of a moral obligation over and above an obligation to merely comply with local laws, to protect children and expose abusers is not a Catholic thing.

Shark Bite For Creationists

An ancient dental gene set governs development and continuous regeneration of teeth in sharks | ScienceDirect

Astonishing news today that the creationist industry's intelligent (sic) designer favours sharks over humans.

Although humans notoriously suffer from all manner of dental problems, including dental caries caused by bacteria, abscesses formed in the gums and jaw when these caries erode the tooth to the point where the dentine and root canals are exposed, and gum diseases leading to the teeth actually falling out, sometime by middle age, the intelligent (sic) designer apparently designed a system for replacing teeth but switched it off in humans, and most of our vertebrate relatives, way back in our evolutionary history. It left the genes there, not doing anything useful though.

St Saturnin being dragged by a bull

This is a blog post I intended to write last Autumn when we got back from Dordogne in France but it got put on the back burner for a while as other things intervened. It is the ludicrously silly tale of Saint Saturnin (or Sarin) of Toulouse, legendary first bishop of Toulouse in Southwest France.

We had some time to kill before our flight home from Toulouse, so spent it in the town, mostly browsing the wonderful vegetable market, but this church down a side street caught our eye so we went to investigate. The church of St Sarin is a wonderful building in mock Romanesque style, slightly reminiscent of Eastern Christian churches. It is a UNESCO World Heritage site and houses what are alleged to be St Saturnin's mortal remains. It is supposedly built on the site where his body was hidden after his curious method of execution. Saint Saturnin is known by several names depending on language and local dialect; Sernin in French, Sarnin in Occitan, Sadurní in Catalan, etc.

It is probably one of the more subtle, insidiously harmful aspects of religion that they encourage humans to feel in some way superior to the rest of nature and somehow to be separate from it, rather than part of the whole with a close connectedness to all of it.

Would this be a sign of intelligence or a sign of either malevolent sadism or stupidity?

Yet, if we fall for the Intelligent Design hoax, this is what we are required to believe this 'intelligent (sic) designer' has done.

Yes, it's our old friend the arms race, only this time it isn't a war between hunter and prey or parasite and host; it's a war between sexes, this time in a species of fruit fly, Drosophila erecta. You might think that sexual reproduction would be a cooperative thing where both sexes have the same interests - getting their respective gametes fused as efficiently as possible. The problem is

Is Fundamentalism An Obsessive Compulsive Disorder?

A thought occurred to me today, prompted by an online friend - fundamentalist religion has some striking parallels with obsessive compulsive disorder (OCD).

1. the thoughts that make you anxious (obsessions)
2. the anxiety you feel
3. the things you do to reduce your anxiety (compulsions).

Early human presence in the Arctic: Evidence from 45,000-year-old mammoth remains | Science

More shocking evidence for creationists emerged this week in the form of evidence of hominid occupation of Northern Siberia some 39,000 years before they believe their god created the Universe.

A team of archaeologist at the Institute for the History of Material Culture of the Russian Academy of Sciences in St. Petersburg have found distinct evidence that a dead mammoth had been injured by stone-tipped weapons before and after death. The conclusion must be that it was killed by an armed hunting party using Stone Age tools. The problem for creationists is that the remains of the 15 year-old male mammoth has been carbon dated to 45,000 years ago, which puts its death before the height of the last Ice Age.

The evidence includes fragment of stone embedded in the bone as well as cuts which must have been made by a sharp instrument capable of cutting into bone. The remains of the mammoth were recovered from a frozen coastal bluff in central northern Siberia near the Kara Sea at 72^o N, well inside the Siberian Arctic and only made accessible in the last twenty years.

Abstract
Archaeological evidence for human dispersal through northern Eurasia before 40,000 years ago is rare. In west Siberia, the northernmost find of that age is located at 57°N. Elsewhere, the earliest presence of humans in the Arctic is commonly thought to be circa

Church of England attendance plunges to record low - Telegraph

Active membership of the Church of England in Britain is in freefall.

The Church has just announced that average church attendance fell by a further 22,000 in 2014 to just 764,700; a fall of 7 percent in just 5 years. Regular weekly total attendance at church is now down to a megre 1.4 percent of the population and fell below 1 million to 980,000 for the first time ever. The C of E estimates that membership is declining by about 1 percent a year due to the deaths of its increasingly aged members alone, and this is at a time when the population is increasing faster than it has done since the late 1940s post-war baby boom.

You have to hand it to Archbishop Braulio Rodriguez Plaza, Bishop of Toledo, Spain and thus the senior Catholic cleric in Spain; he knows his theology!

So, when he announced in Toledo Cathedral on 27 December that women victims of domestic violence only have themselves to blame because they disobeyed their husbands, you can be sure he reached that conclusion from a close reading of Christian scripture in the Bible. It was undoubtedly based on the revealed Word of God in that reliable handbook of morals upon which all Catholics, and indeed all people, can depend with absolute confidence.

God's mouthpiece, the unmarried and officially celibate Braulio Rodriguez Plaza, told the congregation that women could avoid being hit by doing what their husbands tell them and can avoid physical abuse by not asking their husbands for a divorce.

Diversification of self-replicating molecules - Nature Chemistry

The last three years have been dreadful for those who run the creationism industry, but this could be some of the worst news imaginable for them and their willing dupes, and it was only 4 days into the new year when it was published. Scientists led by Jan W. Sadownik at the Centre for Systems Chemistry, Stratingh Institute for Chemistry at the University of Groningen, The Netherlands, believe they may have shown how self-replicating structures could have arisen spontaneously.

This is bound to result in hysterical denialism in creationist circles because it is an indispensable article of faith that life could not possibly have come from non-life so a magician must have made it happen. To a creationist, 'life' is of course some ill-defined or undefined magic ingredient that sets living things apart from non-living things and enables them to do things that non-living things don't do, such as reproducing. To anyone who understands basic biology however, living things are simply things that self-replicate. All the chemistry which goes on to use energy to resist the tendency to disorder is simply a means to that end.

Qur'an Quandary - Where is the Original?

Broolyn Museum, USA

Ask any Muslim what the Qur'an is and who wrote it, and you'll be told almost without exception, that it is Allah's word as revealed in divine revelations to Muhammad through Allah's messenger, the Archangel Gabriel (Jibril). You might even be given the simplistic answer that Muhammad literally wrote it.

This only happened once, apparently. Although spread over some 23 years, there is no record of Allah revealing the same thing several times, least of all the entire Qur'an.

You'll most likely be told that the proof that it is Allah's revealed word is the fact that Muhammad was illiterate and yet was able to write the Qur'an in perfect classical Arabic; that Allah literally guided his hand. This is, of course, the 'lie to children' version. The accepted

Devil's Own Intelligent Design?

Tasmania devil Sarcophilus harrisii

A second transmissible cancer in Tasmanian devils.

A little over 30 years ago, Tasmanian devils, marsupials that lives only on the Australian island of Tasmania, began to develop fatal tumours on their face. It was subsequently found that this devil facial tumour disease (DFTD) was a transmissible cancer which is passed on when one animal bites another on the face and transfers live tumour cells to the new host.

It is thought that these transmitted cells are not recognised by the devils' immune system as foreign and so destroyed because they are genetically so close to the devil's own cells having developed in a highly in-bred population as the population declined and genetic diversity declined with it. Ironically, a parasite has arisen in a host, derived from the host itself.

2015 - Another Miserable Year for Creationism

The title is a partial quote by one Patrick Matthews (20 October 1790 – 8 June 1874) who has a plausible claim to have been the first to published the idea of evolution by natural selection, in 1831, almost 30 years befor Darwin and Wallace published their idea to the Linnean Society. Charles Darwin himself acknowledged his prior claim but pointed to the obscurity of his chosen publication medium - in a book on arboriculture with a very small circulation. Matthews had even published his claim to be the first to describe natural selection in a letter to an obscure gardening magazine.

Has the 'Intelligent Designer' Got OCD?

OCD or Obsessive Compulsive Disorder is characterised by repeatedly and obsessively doing something which appears to have no aim, or at least an aim which isn't furthered by constant repetition.

Yet, when we look at biology, we see examples in great abundance of what would appear to be obsessive, constant repetition which actually achieves nothing, as though the designer is on some sort of mental treadmill and incapable of getting off it - assuming, that is, that you believe in a designer. This is not the act of a mentally healthy or intelligent being.

Why Science Works - Looking at New Evidence

Homo erectus

Source: Wikipedia

PLOS ONE: A Hominin Femur with Archaic Affinities from the Late Pleistocene of Southwest China

A point that's been made many times before here and elsewhere, but which creationists don't seem to be able to understand, is that science progresses essentially because nothing is ever completely ruled out and new evidence is always carefully examined before being accepted or rejected. If acceptance means we need to revise our previous understanding, then we revise our understanding. It would be a complete absurdity for science to know that there was evidence showing that our understanding was wrong yet to ignore it and pretend it just wasn't there.

This of course is in stark contrast to creationism where loons like Ken Ham are actually admired for dogmatically stating that no evidence can ever contradict what creationists 'know' because creationists 'know' the truth, and they didn't get it from the evidence. This dogma, which of course is essential for people trying to maintain a sacred conclusion with the evidence so strongly against them and being added to all the time, enabled creationists to simply wave aside

The 'Millennials' in America have been increasingly rejecting mainstream religion and becoming more atheistic for some time now as shown in a Pew Center survey just a few weeks ago.

As a cultural event, Christmas is becoming an inclusive festival rather than an exclusive one that cynically increases in-group cohesion by automatically excludes religious minorities.

Not surprisingly, the mainstream Christian churches, who were heavily represented on the enquiry board, are crying foul, squealing like stuck pigs and demanding to be allowed to keep their special privileges and power, despite the fact that they are accountable to no-one and represent only a small and decreasing minority of the population.

Why Science Works - Doing It Like Adults

The basic difference between science and religion is that science is grown up while religion is essentially childish. This is illustrated by a controversy which has suddenly blown up in a fairly obscure but nonetheless interesting aspect of evolutionary biology in the last week.

An interesting paper was published a few days ago which seemed to show that horizontal gene transfer (HGT) may account for up to 18% of the tardigrade ('water bear') genome, suggesting that HGT could have played a bigger role in the evolution of multicellular organisms than is generally recognised.

HGT is widely suspected to have played a part in the evolution of prokaryote cells so that acquiring genes evolved in another species could have been a short-cut to evolution or a way for new combinations of genes to come together, analogous to sexual reproduction. In eukaryote cells, the incorporation of prokaryotes was a form of HGT after all, but for HGT to have played a wider role in the evolution of multicellular species would be surprising - hence the interest in this paper and why I wrote about it.

Now, however, another group has published a paper which suggests that the result of the genome analysis may have been an artifact produced by contamination:

How Evolution Gave Us Grannies

Human-specific derived alleles of CD33 and other genes protect against postreproductive cognitive decline

There's something special about a granny. Granddads are special too of course, but not quite like a granny. Ask my grandchildren.

Grandparents are biologically, on the face of it, a little bit of a mystery especially in a social species and especially in one like humans where for most people for most of the time until the discovery of agriculture, life consisted mostly of hunting and gathering food. Anyone not capable of joining in would have been a drain on the resources of those who could so it seems logical to suppose that any process which removed surplus people from the group after their fertile and productive years were over would be advantageous to the group and so would be expected to evolve. In fact, when you look at our closest relatives, chimpanzees, you find that the females tend to die soon after their fertility ceases.

Imagine you're, say, a manufacturer of refrigerators and you've employed a designer to modernise your range. The basic technology is fine - things like the heat-exchange unit, door switch that turns the light on and off - and all you need is some styling to give your range more appeal in the prevailing market.

Now, what would you think if you found this designer was redesigning the heat exchanger or the coolant pump, not to make it any better - in fact some of his designs are worse than the ones you normally use - but because it hadn't occurred to him to use the ones you have in stock. In fact, he didn't know they had ever been designed before.
