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 will use 'apes' instead of 'monkeys', but the underlying ignorance is the same. This question can only seem even slightly intelligent to those who have no idea how speciation by population isolation occurs.

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.

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

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

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.

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.

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.

Creationists - More Green Than They're Cabbage-Looking

I thought I'd share some more holiday snaps. These were taken on the coastal path that runs along the Dorset coast near Durdle Door. They're wild cabbage (Brassica oleracea), although, with so many domestic cabbages around it's highly likely that they will have interbred so they may not be pure wild cabbages. Anyway, they're probably as close to the original wild cabbage as you're going to get in Britain.

The reason they're so abundant in this part of the world is because they evolved as a plant on lime-rich chalk and soil with high salt content. The covering of soil over these chalk deposits is ideal because that's what they've evolved to live on.

So why doesn't it look like a typical cabbage? Because, from this original wild type, by a process of evolution driven by human selection over thousands of years, humans have produced a whole range of different plants for food, each filling a different function and each exaggerating a particular feature inherent in the wild form. This neatly illustrates how a wide range of morphologies can be obtained by a simple selection process. We did the same with the close relatives of the cabbage, B. rapa, B. nigra, B. napus, B. juncea and B. carinata

The reason we were able to do this is because, at some time in their evolution, B. oleracea, B. rapa and B. nigra hybridized to form three entirely new species, B. napus, B. juncea and B. carinata and this gave a wide range of genetic potential. This is of course, a complete refutation of three creationist assertions; that mutations are always harmful, that new information can't arise, and that evolution can't give rise to new species.

Evolving Together In Amazonia


[Body]
Yanomami hunting party
Bacteria bonanza found in remote Amazon village : Nature News & Comment

Much to the chagrin of creationists, no doubt, we can trace our evolution by the evolution of the obligate parasites and symbiont organisms that live on and in us - our microbiome. Just as with the evolution of our lice, the evolution of which and their diversification from the lice which live on the other African apes, maps exactly onto our diversification from a common ancestor with those same apes, so our microbiome can show how human groups are related and have diversified over history.

It has long been suspected that the number of different species in our microbiome declined as we became more hygienic and especially since we discovered antibiotics, so a team who studied the microbiome of the recently-contacted Amazonian tribe, the Yanomami, expected to find a high degree of biodiversity - which they did, finding some 60 unique genes. However, what they didn't expect to find was that a number of the Yanomami gut bacteria have already evolved antibiotic resistance, including resistance to man-made antibiotics.

The general view of antibiotic resistance is that this evolves in bacteria in the presence of antibiotics because the environment is favourable to those with mutations which convey resistance in a basic Darwinian evolution by natural selection. However, the Yanomami have no history of antibiotic use, at least not in the way antibiotics are used by modern medicines.

So, there are two ways to look at this - either antibiotic resistance has evolved in the Yanomami's gut bacteria in response to naturally occurring antibiotics or toxins (toxic to the bacteria) which resemble them, or they have been exposed to man-made antibiotics even though they have remained isolated. This latter seems the least likely and the team believe they eliminated it, so, if their bacteria evolved resistance to man-made antibiotics the probability is that our gut bacteria already had the capacity to 'switch on' resistance even before we began synthesising them. And that raises some worrying possibilities for future antibiotics in our continuing arms race with bacteria.

Even Pebbles on a Beach Refute Creationism

I saw something from our hotel room window a couple of days ago. It's not unusual; you can see it on almost any beach in the right conditions. And it utterly refutes one of creationisms central dogmas (to be fair to creationists, it's more a mindless mantra than a dogma and it's used more like a magic spell than a reasoned argument).

The claim is that you can't get order out of disorder (or chaos). They chant this to try to make the evidence for evolution go away because someone has fooled them into thinking evolution is some sort of increasing order from chaos.

Black Flamingo Poser for Creationists

Here are a few simple little questions for creationists to ignore in the hope they'll go away, like ignored facts do.

These pictures are of the only known all black flamingo. It was photographed in Cyprus in the last few days. There was one previous record of a black flamingo in Israel last year. This one from Cyprus may be a different one, but given that the Israeli one has disappeared and given that Cyprus is an easy flight for a flamingo from Israel, there is a strong possibility that this is the same one, and possibly the only one in the world.

Obviously, the mutation which gives rise to melanism (an overproduction of melanin) is a rare event. We know flamingos produce melanin because they have some black wing feather and some black on their beaks, so what is probably happening here is that the gene(s) controlling when and where the gene for making melanin is switched on (or off) has failed.

The New Forest - No Intelligent Design Here

I thought I'd share a couple of holiday photos with you. We've been to Bournemouth for a few days and spent one day in the nearby New Forest, just wandering around, looking at birds and flowers and generally appreciating nature.

But when you look at nature and really try to understand and appreciate why things are as they are, the one thing that stands out most markedly is how utterly stupid so much of it is. It is full of examples of pointless and ultimately wasteful arms races as one species seeks to gain an advantage over another in the general competition for resources or even as one species tries to use another as a resource and the other tries to resist it.

The result is the wonderful complexity and diversity we can see and enjoy but to pretend it all has some ultimate purpose directed towards humans is sheer anthropocentric arrogance.

Look at these pictures of thicker broad-leaf woodland and what do you see?

Bearing in mind that it's early Spring here in the UK and most trees are just breaking into leaf, so what you are seeing is the wood without it's canopy. In a matter of weeks this forest floor will be considerably darker than what you see here.

How Europeans Evolved

Archetypal European hunter-gatherer
How Europeans evolved white skin | Science/AAAS | News

A new study has provided more detail on the discovery reported a year ago that Europeans evolved white skin fairly rapidly about 8000 years ago but not, as one might assume, in Europe itself but rather in three different distinct populations of hunter-gatherers and farmers who moved into Europe, each contributing genes to the 'European' genome.

A paper published in February this year showed that the origin of the Indo-European languages was probably a population of nomadic herders from the Russian steppe north of the Black Sea who appear to have migrated massively into Europe about 4500 years ago. These people are known as the Yamna Culture. Indo-European languages exist now in about 400 different languages and dialects from Irish in the west to Hindi and Urdu in the east.

Scientists have revised their estimate of when the last common ancestor of men lived, bringing it much closer to the estimate of when the last common ancestor of women lived. The basis for this estimate is the range of diversity in the Y-chromosome and the estimated rate of mutation.

The calculation for women is based on the same principle but based on mitochondrial DNA (mDNA). We inherit our mDNA from our mothers but males inherit their Y-chromosome from their father. Women don't have a Y-chromosome.

Origin of the Adam & Eve Myth


A pair of Old Testament scholars at Holland's Protestant Theological University, Amsterdam & Groningen believe they have found the origins of the Adam & Eve myth in the Hebrew Bible. It is a version of an old Canaanite myth based on the original Canaanite pantheon.

Dr Marjo Korpel and Professor Emeritus J.C. de Moor claim to have found the evidence on Ugaritic clay tablets of a 13th-century BCE story about the gods who lived on the slopes of Mount Ararat, in modern-day Turkey, in the 'vineyard of the great gods', identified with the Garden of Eden.

The top god was El the creator god and amongst the lesser gods in the pantheon or Elohim (children of El) were Adam and his wife. El is, of course, the Hebrew, Christian and Muslim god whom Arabic speakers still call Allah.

Moral Compass - The Catholic Church and Excommunication

Fr. Jose Mercau, Excommunicated
Last November, Pope Francis defrocked and excommunicated a convicted paedophile priest from Argentina. Of course, many priests have been excommunicated by the Catholic Church before, but the case of Fr. Jose Mercau was unusual; he is one of the only Catholic priests to have been excommunicated for sexual abuse (technically rape) of a minor.

Pope Francis was apparently trying to convince the world that the Catholic Church had recognised the error of its ways and would no longer tolerate, facilitate and protect priests and nuns who abused children and vulnerable adults and now took a dim view of these previously accepted clerical recreational pass-times.

More Fascist Catholics

Fr. Josef Tiso with his friend and role model, Adolf Hitler
In addition to their close involvement in creating the first fascist state in Europe in Portugal, and their support for Italian and Spanish fascism, the Catholic Church was actively involved in another even more extreme fascist regime in Slovakia.

Unlike Portugal and Spain which stayed out of World War II and have no history of sending Jews to Hitler's slave labour and death camps, Slovakia, under the leadership of a Catholic priest and fascist dictator, Fr. Josef Tiso, enthusiastically shipped around 60% of Slovakian Jews (over 52,000 of the population of 89,000) to the death camps, mostly Auschwitz.

Mother Teresa and the Paedophile Priest

Fr. Donald McGuire, Jesuit, serial paedophile and spiritual advisor to Mother Teresa
Catholicism's favourite new demi-saint, "The Blessed" Teresa of Calcutta, was a friend of a paedophile priest and intervened to get him reinstated in his parish, where he subsequently carried on with his predatory paedophilia, sexually abusing more boys before finally being arrested and imprisoned.

This was revealed in papers leaked to the San Francisco newspaper, SF Weekly in January 2012.

The priest in question was Fr. Donald McGuire, currently serving a 25 year sentence for what the judge described as:

[P]articularly detestable because he abused the trust of parents and had perversely taken advantage of their children. [His Actions were] abhorrent, unacceptable, and‘a very, very serious sin.

Even Monkeyflowers Ridicule Creationists

M. lewisii (A), an F1 hybrid (B), M. cardinalis (C), and examples of variation in floral traits found in F2 hybrids (D–L).
Pollinator preference and the evolution of floral traits in monkeyflowers (Mimulus)

Imagine for a moment a species of flowering plant with a three important genes, each of which has two different alleles. Let's say Gene A which can be A1 or A2, gene B which can be B1 or B2 and gene C which can be C1 or C2. Gene A determining flower shape, gene B determining flower colour and gene C determining how much nectar the flower produces.

Now imagine two different pollinators which transfer pollen from one flower to another while gathering nectar, one having a preference for one shape and colour and the other having a preference for a different colour and more nectar.

It doesn't take a genius to work out what will happen. The flowers with the alleles which attract one pollinator are much more likely to pollinate other flowers with those same alleles and those with the other alleles will be much more likely to pollinate the flowers with these alleles.

In effect, there will be a premating or 'prezygotic' barrier to cross-pollination between plants with different combinations of alleles and selection pressure against permutations of alleles

Seeing Evidence Of Inept Design

Müller cells separate between wavelengths to improve day vision with minimal effect upon night vision : Nature Communications : Nature Publishing Group

Although they will probably deny it, even creationists must be aware of the inept design that is the vertebrate eye where the retina is wired backwards, so the nerves from the photoreceptor have to travel towards the source of light then across the surface of the retina to join up with the main optic nerve and finally back down through the retina, causing the 'blind spot' - an area of the retina where light doesn't register.

Our neural circuitry has to infill this area for us so we don't notice it. Consequently, there is a small risk that we won't notice pieces of grit, small flies and other foreign bodies that get in our eyes, and the nerves going in the 'wrong' direction inevitably create a barrier for the light to get through.

In effect, the photoreceptors are are actually shielded by their circuitry. It's like the designer of a digital camera putting all the wiring and processors between the lens and the detector. Creationists call this 'intelligent'.

Creationist Nightmare Approaches

Chemists claim to have solved riddle of how life began on Earth

The creationist nightmare scenario came a little closer a couple of days ago when a team of scientists published a paper in the Journal of Nature Chemistry, demonstrating that the three chemical precursors for building the basic components of a cell - RNA, lipids and proteins - can all be built by the same chemical process.

The nightmare scenario for creationists is of course the closure of one of the few remaining gaps in which they arbitrarily sit their favourite god and claim this proves its existence. This transparently circular reasoning and deliberate use of the false dichotomy fallacy is also a major plank in the under cover, pseudoscientific form of creationism, intelligent (sic) design. The belief seems to be that, if they can find something science can't currently explain then the only alternative explanation on offer is that their imaginary invisible friend did it. In normal life this form of argument would be seen as laughingly childish but religion has managed to get away with it for centuries.
