Chick Embryos Reverted to Dinosaur Features

By blocking two genes that are activated when chicken embryos grow their beaks, U.S. researchers caused their jaws to 'revert' to a velociraptor-like or reptile-like snout.

Dinosaur-like snouts grown on chicken embryos - Technology & Science - CBC News

It's more bad news for the Creationism and the Intelligent Design industry, and this one is going to take a lot of explaining away.

Scientists have shown that inhibiting a couple of genes responsible for facial development in domestic hen embryos, causes the chick to grow a dinosaur face instead of a bird face. The authors also suggest their method could be used to investigate the mechanism of other major transitions in vertebrate history.

Missing link in the evolution of complex cells discovered

It must be puzzling and disconcerting for creationists the way a new scientific discovery never seems to support creationism and always seems to support science. Not that this will affect creationist superstition, of course, but there is a very simple explanation for this: science is based on evidence and so is demonstrably true; creationism is a superstition with no supporting evidence and so is not demonstrably true.

It's entirely predictable therefore that evidence will always support science and never supports

A friend on Facebook has just drawn my attention to this scientific discovery from last February. I can't think how I missed it with such a catchy title to the paper (Human-specific gene ARHGAP11B promotes basal progenitor amplification and neocortex expansion). Hmm...

It appears then that a single gene might be responsible the the most profound difference between us and the other apes and between us and our immediate hominid ancestors.

Faking It At Lourdes

The Lourdes shrine to Bernadette Soubirous

Bernadette Soubirous

Continuing my series on the fake miracles used by the Catholic Church to keep the faithful faithful and keep the money flowing in, this one deals with the carefully concocted fraud at Lourdes, France.

This fake is, like the Fatima fake, based on the fantasies of an illiterate peasant girl, Bernadette Soubirous, from a remote village who, as with Lúcia Santos at Fatima, seems to have been trying to impress a couple of friends and who found herself locked into her own childish fantasies by a Church keen to exploit her.

There are three elements to the Lourdes 'miracle':

• The 'visions' of 14 year-old Bernadette Soubirous.
• The 'miracle' cures which come from drinking the spring water and praying at the grotto.
• The 'incorruptibility' of Bernadette Soubirous' dead body.

None of these stand up to close scrutiny.

Faking It At Fatima

With the approaching 98th anniversary of the supposed miracles of Fatima, Portugal, it's worth looking at this particular example of how the Catholic Church operates and how truth becomes an early victim in its incessant search for spectacles to keep the faithful faithful and the money flowing in.

First a bit about 'miracles' in general.

The Catholic Church is notorious for using 'miracles' to convince its believers that it is the one true church, believing in the one true god and that it has a special relationship with the ruler and creator of the Universe. The problem it has to overcome is the problem of having no evidence whatsoever for that claim, so it needs trickery. Experience has shown that 'miracles' are particular effective on the poor, uneducated and unsophisticated people who make up the bulk of Catholic congregations worldwide.

Miracles are especially useful for the Church because, by definition, there can be no physical contradictory evidence, just as there can be no physical evidence for them, because otherwise they wouldn't be supernatural 'miracles' but perfectly natural events with perfectly natural explanations. 'Faith' fills the gap and renders the lack of evidence a mere inconvenience, even, in some strange way, confirmation.

Ignorance & Double-Think - The Bear Necessities of Creationism

Genetically isolated sloth bears rely on habitat corridors to connect populations -- ScienceDaily

This paper is interesting from an ecological point of view, illustrating as it does the importance of maintaining a diverse habitat in order to maintain biodiversity, but it also neatly illustrates something which creationists either genuinely don't understand or about which they feign ignorance.

One of the most annoying questions creationists keep asking, as though they imagine it to be a killer question which destroys the idea of evolution, is, "If humans evolved out of monkeys, why are there still monkeys?" The slightly more educated ones

There's no getting away from it; if you believe in an intelligent designer (i.e. God, although ID advocates aren't supposed to say that because it gives the game away that ID is biblical literalism in disguise) you believe it intends us to either be very sick, or to put other people's poo up our bottoms.

You see, this intelligent designer designed a nasty little spore-forming bacillus called Clostridium difficile which seems to have only one function - when it gets the chance it causes a really unpleasant condition in

A team of Chinese paleontologists has discovered a spectacularly well preserved fossil bird from 130 million years ago which neatly fills the gap in the fossil record between proto-birds such as archaeopteryx and modern birds.

This pushes the earliest known ancestor of modern birds back 5 million years and, because it has several well-developed adaptations, shows the main features characteristic of modern birds must have evolved

The Future for World Religion

The Future of World Religions: Population Growth Projections, 2010-2050 | Pew Research Center's Religion & Public Life Project

The recent Pew Research Center's forecast for the growth of world religion has been greeted by theists in general with something approaching glee because it appears to forecast a decline in the proportion of people with no religious affiliation, which includes Atheists and agnostics, although this glee tends to become muted, especially amongst Christians, when they look below the headlines, because the same figures show the number of Muslims worldwide almost equalling the number of Christians by 2050.

However, it reveals something dark and nasty at the heart of religion and upon which religion depends; something of which no religious person with any sense of human decency can be proud.

And in the developed economies the forecast is far from good news for theism. Throughout much of it, the forecast is that the recent growth in non-affiliation and non-belief will continue to increase both in absolute numbers and in proportion of the population. In fact, the number of non-affiliated is set to increase throughout the world but is forecast to decline in percentage terms because of a larger increase in the number of religious people.

Ken Ham Reaches A New Low

Ken Ham is no exception to the routine, run of the mill creationist pseudoscientists in being prepared to lie through his teeth and stoop to any misrepresentation of science to his scientifically illiterate victims for money.

He even boasts openly about teaching the unfortunate children of creationist parents how to disrupt science class at school or talks by scientists, and strike a blow for Jesus, by asking "Were you there?", and so avoid learning anything.

Intelligent Design Arguments Drying Up - Water, Water Everywhere!

Water could have been abundant in first billion years after the Big Bang -- ScienceDaily

Regular readers will remember the dismay that creationists who trot out the 'Goldilocks' argument for intelligent design displayed when it was discovered that yet another body in the solar system may have abundant water.

The problem they have is that they have to convince those to whom they are selling the notion of Intelligent Design that Earth is unique in just about everything that affects life on it - so water on Earth has to be presented as something hugely unlikely, just as Earth's distance from the sun has to be.

Maybe it's just my perception but it seems to me that creationists are not using this argument so frequently

Convergent Evolution of Mechanically Optimal Locomotion in Aquatic Invertebrates and Vertebrates - PLOS Biology

A nice example here of how the environment drives evolution by imposing limits on what is possible and what is optimal, in this case by the physics of fluid dynamics.

Researchers from Northwestern University in Evanston Illinois studied 22 different species in eight clades from three aquatic phyla of a wide range of shapes and sizes that all swim by 'median/paired fin swimming', in other words, by using a pair of long fins, running along each side of their body.

Ancient megadrought entombed dodos in poisonous fecal cocktail | Science/AAAS | News

For an illustration of the inability of evolution to predict the future and so lead a species to, if not actual extinction, then the brink of it, it would be hard to find a better example than this one from the Indian Ocean island of Mauritius.

Mauritius is famous, for amongst other things, being the home of that enduring icon of extinction, the dodo. The dodo was a flightless pigeon (itself an example of evolution because flight must have been something it lost after having arrived on the island) which went extinct in around 1662 probably through being hunted for food by humans and predated on by pigs. Hunting is probably too strong a word, as dodos reputedly had no fear of humans or any other predators, as there were none on the island prior to the arrival of European sailors. The Mauritius giant tortoise also went extinct for much the same reason.

But this wasn't the only example of dodos being incapable of adapting

Creation Ministries International is the Australian version of Answers in Genesis from which it split when it's founder, Dr. Carl Wieland fell out with it's then president, Ken Ham, who went off to the USA where more money could be made.

It is little different to AiG in that it specialises in misrepresenting science to misinform the people to whom it sells books, and Christian fundamentalist groups who invite guest speakers to provide spurious confirmation of their existing bias by giving it the semblance of a scientific basis.

Closing The Gap - Why Science Is True And Religions Aren't

The thing about science is that it tends to converge on a single answer, no matter what the starting point. Religions, on the other hand, rarely, if ever converge. If anything, they tend to diverge and splinter into different, mutually hostile factions, each clinging to its 'answer', each unable to muster up arguments why their answer is the right one while all the others have it wrong and each never being able to find that definitive, clinching piece of evidence that would make their arguments indisputable and win over the dissenters.

The reason for this is very simple, and is the reason

UKIP are currently falling in the polls following some disastrous performances by Farage in televised live debates (something he later blamed on a bad back) and are scraping the bottom of the barrel for support. They are now forecast by some pollsters to get somewhere between 0 and 1 candidates elected and Farage may well lose the seat he himself is standing in.

Pain In The Back For Creationists

It's no secret that humans have back problems. About eight in ten of us will suffer back pain at some point in our lives, often chronically. One person in twenty will slip a disc - the fibrous cushions between the bodies of our vertebrae - most often in our lumbar region and most commonly, but by no means exclusively, in men between the ages of 30 and 55.

Actually, the disc doesn't literally slip; the capsule surrounding it tears and some of the contents herniate out. This causes inflammation and swelling; the muscles spasm to protect the injury and the swelling can put pressure on the sciatic nerves coming out of the spine and going to the legs. This causes referred leg pain or sciatica.

Jim Wells resigns as Northern Ireland health minister - BBC News

The Young Earth Creationist and fundamentalist Christian, Jim Wells, who was appointed Health Minister in the Northern Ireland Power-Sharing Executive only last September (see Loon At The Top), has been forced to resign over remarks made in his campaign to become the DUP member for South Down in the Westminster Parliament. Wells had told a meeting that children brought up in households with same sex partnerships were much more likely to be neglected. The meeting was interrupted by uproar from the audience.

He is later alleged to have repeated his remarks during a conversation with a lesbian couple during door-to-door canvassing. Wells later tried to go into the couple's house to apologise but they refused to let him in or to speak to him. The daughter of one of the women involved, a former staunch DUP supporter, later said her mother would no longer be voting for the party. Although expressing regret that his bigotry had caused offense, whilst not withdrawing the allegation, Wells cited his wife's serious illness as the reason for his resignation, not his politically embarrassing bigotry.

Chimpanzees Make Spears To Hunt With

It's been many years now since we realised the thing that we thought made us uniquely human - the ability to use tools - isn't unique at all, but we still clung to the notion that, while many species use things like sticks and stones as tools, humans were the only species to actually make them. That too has now had to be abandoned since chimpanzees were seen making tools out of plant stems to fish for termites and crows have been filmed making tools out of wire - not a natural material - to solve complex problems.

Now a group of savannah chimpanzees (Pan troglodytes verus) has been observed not only using spears to hunt with, but selecting suitable tree branches and sharpening a point on them. Like

How Wolves Evolved Into Dogs

How the wolf became the dog

There is no doubt now that the domestic dog is a domesticated wolf. It has recently been reclassified by taxonomists as a subspecies of wolf, Canis lupus, so instead of Canis familiaris it is now Canis lupus familiaris. It was almost certainly the first animal to be domesticated but ideas have differed over how this came about.

In 1907, Francis Galton proposed that humans had taken wolf puppies back to their camp and raised them, maybe as playthings for the children, but this view is now seen as naive. You can raise a wolf puppy by hand but you don't get a dog; you get a dangerous wild animal. The genes of children who played with growing wolf puppies would probably have been quite quickly eliminated from the human gene pool as well as the puppies' genes being eliminated from the wolf gene pool.

So, clearly something else happened.
