Ecological speciation of bacteriophage lambda in allopatry and sympatry | Science
Two central article of faith in creationist circles are that speciation has never been observed and that evolution can't be replicated in a laboratory.
So essential are these dogmas to creationism that nothing will shake their faith in them, not even the evidence of evolution being replicated in a laboratory and speciation being observed in the process. You can rarely make any progress with a creationist without these 'killer' assertions being thrown into the debate. They are almost the motto or battle-cry of creationism. So we can be sure the best available dismissal techniques will be brought to bear on the paper published in Nature a few days ago showing exactly that.
That's right, creationists, scientists have observed evolution, including speciation, in the laboratory. And their experiment is reproducible.

Why We Atheists Are Hated. We Frighten Them!
What If They’re Right About the Afterlife? Evidence of the Role of Existential Threat on Anti-Atheist Prejudice.
In America and probably many other countries, though much less so in the United Kingdom and probably most of Western Europe, Atheists are amongst the least trusted of all people. Some surveys even putting them on a par with Islamic extremists.
The reasons given are usually that Atheists don't have a moral framework and therefore have no way of knowing that rape, theft, murder, etc. are wrong and that complete selfishness and disregard for others is to be expected. That this is manifest nonsense when the actual behaviour of known Atheists is observed will show, does not seem to affect the underlying cultural assumption that a hoped-for reward or the threat of punishment are the only things which motivate people to behave well and that no-one knew how to behave before we had the Christian Bible.
A paper published in the journal, Social Psychology and Personal Science in September 2015 sheds some light on this strange and irrational attitude. The authors cite 'Terror Management Theory' as the likely cause:

Gut Microbes Influence Our Evolution
Diet-Microbiota Interactions Mediate Global Epigenetic Programming in Multiple Host Tissues | Molecular Cell:
We need to stop thinking of the higher animals (and maybe plants) as a single species with a single genome as the unit on which natural selection operates.
We, along with all higher animals, are colonies of more-or-less cooperating species each of which has it's own evolutionary 'agenda' but each of which, like us, is inextricably bound up with the evolution of the colony as a whole. In effect, what is evolving is the colony with its distributed genome. This also has damaging implications for creationism and its dressed up little brother, intelligent (sic) design.

Those Poor Christians Are Being Persecuted Again!
John Freshwater |
In a ruling that will no doubt shock and enrage Christian fundamentalists everywhere, the Ohio Supreme Court has confirmed once again that even Christians have to obey the laws of the land. This will almost certainly be presented as a war on Christianity and a denial of their 'freedom' to disregard laws they don't like whilst demanding the right to impose their own 'laws' on everyone else.
The ruling brings to an end a four-year campaign to have a fundamentalist Christian creationist teacher, sacked for disregarding instructions not to teach his superstition as fact to public school children in contravention of the US Constitution's 'Establishment' clause, reinstated and to be allowed to continue to flout the law, ignore the Constitution and use his salaried position to teach his creationist version of 'science' to school children.
In a 4:3 verdict, the court ruled:
After detailed review of the voluminous record in this case, we hold that the court of appeals did not err in affirming the termination. The trial court properly found that the record supports, by clear and convincing evidence, Freshwater’s termination for insubordination in failing to

A Newly-Discovered Species of Archaic Humans?
Two Vanuatu girls. Photo credit: Graham Crumb Source: Wikipedia |
It's hard to see how the Abrahamic religions can continue to hold on to the myth of a single ancestral couple for the whole of humanity in the face of the onslaught from scientific evidence that this model is nonsensical. The Catholic Church's attempt to subscribe to it as an essential part of their dogma whilst also accepting the scientific evidence for the evolution of humans from a common ancestor with other apes and through a series of archaic pre-modern hominids is becoming increasingly untenable.

Why Christians Supported the Very Un-Christian Trump
How the faithful voted: A preliminary 2016 analysis | Pew Research Center
One of the most outstanding features of the American presidential election was the complete abandonment of any pretense of morality by the evangelical white conservative Christians in their eagerness to promote a white supremacist, misogynist, serial adulterer, self-confessed serial molester of women and public mocker of disabled people, to the top job. Almost as noticeable was the eerie silence from the black evangelicals and Catholics, even the hispanic Catholic leaders.

Canine Conundrum For Creationists
Amy2B copy number variation reveals starch diet adaptations in ancient European dogs | Open Science
Here is a sweet treat for dog lovers, anthropologists and evolutionary biologists, though not so much for creationists.
An open access paper published very recently in Royal Society Open Science not only sheds light on domestic dog and modern human co-evolution but illustrates an important principle in evolutionary biology: evolution will occur in the presence of a change in the environment with little or no change in the information in the genome. It also shows how gene duplication can play an enormous role in the evolution of a species.

I've written several posts with examples of the sheer malevolent nastiness of creationists' notional intelligent (sic) designer, asking if it can get any nastier, but this latest example really does take some beating.

Brain Development and Creationism
Evolution of Osteocrin as an activity-regulated factor in the primate brain : Nature : Nature Research
Scientists at Harvard Medical School have discovered that a gene that regulates bone and muscle growth may also be involved in brain development and activity in primates, including humans. In particular, this gene appears to be active in areas of the brain involved in cognition and learning. Their finding were published yesterday in Nature.
This is a good example of how genes can be used by the evolutionary process for new functions, and, because this particular retooled gene is only found in primates, it suggests that the repurposing occurred in a common ancestor of this clade.

Popes are supposed to be infallible and to be the absolute, ultimate authority on all spiritual and ecumenical matters - but not when it comes to trying to ride two horses simultaneously, it seems.
Face with a question from a Swiss journalist about whether women ever being admitted to the Catholic priesthood, Pope Francis confirmed that the ban would remain in place. When pressed he blamed Pope John Paul II who confirmed the ban in 1994, saying, "Saint Pope John Paul II had the last clear word on this and it stands, this stands".

A Christian Husband's Guide to Sleeping Around
A good Christian man with a wife and bit on the side. |
Still trying to understand why American fundamentalist Christians regard Donald Trump as such a great role model and eminently suited to being President of the USA, I looked further into how Christian fundamentalists see a man's marital infidelities. So I turned again to the Biblical Gender Roles blog for an explanation.
Maybe fundamentalist Christians won't be surprised by the hypocritical double standards and cherry-picking approach to the Bible that I found there, but I suspect normal people might at least raise an eyebrow. After all, don't fundamentalists normally make a big thing of the Ten Commandments, including the instruction to not covet a neighbour's wife? Well, that was a mistake, apparently, or maybe it just applies to other people.

Wholesome Christian husband using God-approved moral blackmail to force sexual compliance. |
Remember, Donald Trump's seduction technique, and one of the qualities that so endear him to fundamentalist Christians, is to grab a passing woman by her 'pussy' and expect her to become uncontrollably aroused at the thought of his large wealth. So how does this fit in with current Christian teaching? For this I turned to the fundamentalist Christian blogsite, Biblical Gender Roles.

Christian Hypocrisy and Donald Trump
Donald Trump. Candidate for Christian values. |
It can best be summed up in a single word - 'hypocrisy'. The longer version is 'power and influence at any price'.
Of course, with the Bible being a cherry-picker's delight, with it being possible to find a passage or two, or maybe a whole chapter, that supports almost any cause, it can be difficult to discern what might be termed 'Christian values' in the it. And most of these can usually be contradicted with another passage somewhere, but perhaps the nearest thing to a definitive statement of what Christian are supposed to behave like is the so-called Beatitudes from the 'sermon on the mount'.

'Alien' Life Beneath Canada?
Kidd Creek Mine, Timmins, Ontario. |
According to research results publish open access in Nature Communications yesterday, there could be life in water which has been isolated in rocks deep below Earth's surface for at least 1 billion years and possibly 2.7 billion years, i.e for maybe half the life of the planet.
This water, which is now seeping to the deep Kidd Creek mine 2.4 Km below Timmins, Northern Ontario, Canada, had been shown to have been isolated for this long in 2013. What is new in yesterday's report is the news that this water is capable of sustaining sulphur-based life similar to that found elsewhere in isolated subsurface water. Bacterial life has been found in similar structures in South Africa but this, if proven, would be ten times older.

We are getting used to the relatively new science of genome analysis throwing up regular surprises and calling into question a few things we thought we understood reasonably well, but then that's science. Science wouldn't be any use if we didn't keep learning new things, revising old assumptions and so making progress.
For example, we once thought that modern humans evolved in East (or possibly South) Africa and that a small band of Homo sapiens followed an earlier migration of H. erectus and left Africa for Eurasia and thence into the Americas and the Pacific. We

'Gay Cake' Victory Over Christian Bigotry

In a victory for basic human rights over Christian bigotry, the Court of Appeal has ruled that a Northern Ireland baker was wrong to refuse to make and decorate a cake for a gay campaign to legalise same-sex marriage because they disagreed with their life-style. The cake was to bear the slogan 'Support gay marriage".
Ashers, a family firm of Belfast, initially accepted the order from gay rights activist, Gareth Lee, but then declined it on the grounds that it went against their religious belief. The cake had been ordered for a private party to celebrate the end of Northern Ireland Anti-homophobic Week.

Double Dose Of Frog DNA Plagues Creationism
The genome of the frog X. laevis (top) is roughly double that of its relative, X. tropicalis (bottom). Credit: Professor Atsushi Suzuki, Hiroshima University |
There are so many different forms of creationism that it's difficult to find any consistency between any two creationists and even in the same creationist at times. This make it handy for them to move the goalposts around of course because they can always change this or that definition or declare this or that impossible or possible according to the needs of the argument in hand.
However, there are a couple of pieces of dogma that are fairly consistently trotted out and are common to most flavours of creationism:
- Mutations are always harmful and can't give rise to new information.
- New species can't arise by natural processes so have to be created.
It must come as a shock then when a scientific paper is published showing both of these to be untrue, and untrue moreover in the same species!

Something Fishy About Jaws!

A couple more of those little unknowns that drives science forward may have been solved this week by a team from Uppsala University, Sweden and the Institute of Vertebrate Paleontology and Paleoanthropology, Beijing, China.
The first is where did our jaws come from in our evolutionary past and the second is where exactly do the 'armour-plated', fish-like placoderms fit in with the evolution of bony fish and via them, the tetrapods, including us mammals. The Silurian placoderms lived over 400 million years ago and it was not clear whether they were the direct ancestors of the bony fish or a sister clade with the ancestral bony fish along with the cartilaginous fish.

Early cave art and ancient DNA record the origin of European bison | Nature Communications.
For a creationist claim, the assertion that no new species have been seen to evolve takes some beating for its sheer denial of the readily available data. Now geneticists working at the Australian Centre for Ancient DNA at the University of Adelaide, have shown that even the Stone Age painters of the caves such as Lascaux Cave, France, captured one such event in their art. Their findings were published yesterday in Nature Communications.

Lessons From Cyprus - Aphrodite, A Goddess For All Men
Birth of Venus (Aphrodite). Sandro Botticelli (1445-1510) |
Cyprus, that beautiful, arid island in the eastern Mediterranean and possession of every Mediterranean power from Ancient Egypt, Greece, Rome, Byzantium, Ottoman Turkey, and latterly Britain, is the place of legend. It is remote enough to be mysterious and culturally distinct, yet close enough to the major centres of regional power to be familiar. Not surprisingly, Cyprus had its own gods and its own legends about gods but, unlike those of Minoan Crete, we know quite a lot more about these gods if for no other reason than that, again unlike Minoan Create, the culture which worshipped the Cypriot gods didn't get wiped out in a sudden catastrophic natural disaster.

'Kind' Pope Francis Bashing the Gays Again!
Pope Francis: A 'global war' seeks to destroy marriage.
A few days ago in the Georgian capital, Tbilisi, the Pope gave an almost perfect illustration of how the Catholic Church is completely incapable of reforming itself without giving up being the Catholic Church.
He reportedly told an audience of priests and seminarians that there is a 'global war to destroy marriage'. He was of course referring to moves to legalise same-sex marriage and so give equal human rights to homosexual couples rather than to stigmatise, persecute and deny basic rights to them as the church would prefer.

Altruism is one of those evolutionary traits that creationists claim not to be able to comprehend for a couple of reasons:
- It seems to require some sort of morality and a knowledge of outcomes, and they normally find it hard to think why anyone would do something for someone else if there is no promise of a reward. At least that is normally behind their claim that you need their god to be moral.
- How can a trait which is detrimental to the individual in that it causes loss or harm, be advantageous in the Darwinian sense, and so be passed on differentially in preference to a trait for selfishness?

It's now well known that humans are not the only species capable of learning new skills and passing these on to others.
Despite the old religious-based view of humans as having a unique intelligence not seen in other animals, and thus standing us apart from the rest of 'creation', like tool construction and use and the ability to solve problems, learning and culture are now being seen in a whole range of other animals. Until now though, this had been confined mostly to vertebrates and almost exclusively to mammals and birds.

Does God Favour Axolotls?
Early development reveals axolotl mysteries -- ScienceDaily
You can understand a creator being quite fond of axolotls. There is something fascinating about them, especially the way they look and behave a lot like some sort of fish with legs and even breathe underwater using gills.
Basically, the Mexican axolotl, Ambystoma mexicanum, is a big salamander which spends most of its life as a tadpole. They even breed in their juvenile form and only become land-based adults when their water dries up. They also have a massive genome by mammalian standards, all packed into just fourteen chromosomes. Their genome is far larger than any other known amphibians but this appears to be due almost entirely to repetitive gene duplication.

We Owe It All To Pollution!
Dr Rosalie Tostevin. Field work in Namibia. Source: UCL Credit: Fred Bowyer |
The great thing about science is the way it all meshes neatly together. Although there may currently be gaps in our understanding these gaps are getting smaller and the piece that fills the gap almost always neatly fits in with what we already know.
Of course, there may be occasions when the piece doesn't quite fit and so we need to look again at the surrounding science, but in the long run, these conflicts are always resolved to smooth out the wrinkles and fill in the cracks.
And another one of these little gaps looks as though it might have been filled in. Despite the ever and unrealistically optimistic hope of creationists that the very next gap will be found to be where their god lives, no such god was found by science yet again. The answer was entirely consistent with what we already know - which is inevitable, when you think about it. It is inevitable because science is about reality and reality is consistent.
Talking Neanderthals Give Creationists Earache!

Creationists struggle with archaic human like Neanderthals, Homo erectus and H. habilis trying out various ways to dismiss them as diseased and deformed individuals, forgeries, etc.
The slightly less delusional ones have learned that there are limits to the amount of evidence that can be denied without looking more than a little insane, so have learned to accept a form of evolution, albeit a ludicrously rapid one which requires several fully-formed new species to spring into existence every generation. To these, all hominids are merely minor variations and have all developed from the fully human people who supposedly got off the Ark about 4000 years ago.

Has The 'Intelligent Designer' Been Tweaking Zika?
Fatal Zika Virus Infection with Secondary Nonsexual Transmission - NEMJ Correspondence
Parasites in general and viruses like the zika virus in particular continue to be an embarrassment to creationists who insist everything is intelligently designed for a purpose.
The main embarrassment of course is in explaining why it designed them in the first place, although 'The Fall' is regularly trotted out as the excuse. But, this gives away the fact that the 'intelligent (sic) designer' is the Christian god and that intelligent design 'science' is fundamentalist, Bible-literalist Christianity posing as science to try to sneak past the 'Establishment Clause' in the US Constitution.

But, this gives away the fact that the 'intelligent (sic) designer' is the Christian god and that intelligent design 'science' is fundamentalist, Bible-literalist Christianity posing as science to try to sneak past the 'Establishment Clause' in the US Constitution.

Ostrich Eggs Cracking Creationism

An open access paper published yesterday shows something which should be frightening the wits out of creationists frauds, even if their willing dupes won't understand or accept the significance of it. An international team of researchers has shown the proteins can persist in the fossil record for at least 3.8 million years - some 50 times longer than DNA.
The protein was found bound to the fossilised fragments of ostrich eggshells. The finding open up the possibility of detailed analysis of human evolution where DNA has not survived.

Doing Science With Elephants

How can elephant DNA teach us about why science works and creationism doesn't?
Creationists, with their simplistic black vs. white view of the world, often pour scorn and derision on science for changing its collective mind so frequently. This comes of course from a mindset which values 'certainty', no matter how illusory, more highly than truth. Truth is sacrificed in the search for the cosy comfort of 'certainty'.
But science doesn't look for certainty. Science simply tries to get as close to the truth as possible and a truth which can be demonstrated. The analogy is of a car being driven to a destination. Every movement on that journey is a sign of progress, not a sign of failure. Constant change of position is the method of progress. Science has to change its collective mind to make progress. Religions fail to make progress because they can't change their collective minds without abandoning their religion. With religions, the dogma is everything.
So what has this to do with elephant DNA?

Christians 'Cleanse the Streets' After Gay Pride March
The Freethinker - The voice of atheism since 1881 » In Belgrade, priests ‘cleanse’ the streets after Pride event
In an orgy of gratuitous anti-gay hate and abuse, Serbian Orthodox Christians, incensed at a gay pride parade in the Serbian capita, Belgrade, held a rally and march to ritually cleanse the streets of 'homosexual contamination'. The parade had been heavily protected by police preventing Orthodox and far-right nationalist extremists violently breaking it up as earlier years.
Amongst the expressions of Christian 'love' was a banner showing a homosexual being pushed into Hellfire by a Christian with a cross. The love of Jesus

Mexican Priests Still Raping Children
Catholic Church ACQUITS Mexican priest who admitted to raping 30 young girls | Daily Mail Online
In an extraordinary move, and one which flies in the face of official Vatican pronouncements on the subject of child-abusing Catholic priests, the Archdiocese of Mexico has formally acquitted an HIV carrying priest of any wrongdoing even though he admitted having sex with about 30 girls aged between 5 and 10 over many years.
The assaults were committed on indigenous girls in the southern province of Oaxaca which has a predominantly indigenous population and where the influence of the Catholic Church is very powerful, especially amongst the indigenous people. No criminal charges have yet been brought against the priest, José Ataulfo Garcia, despite his admission, almost certainly due to the Church's political influence in Mexico.
