Child Porn Priest Rescued by Vatican

Monsignor Carlo Capella
"Downloaded child pornography using a Canadian church online address".
Lawyer says Vatican diplomat wanted for child porn offences should be sent back to Canada - Windsor - CBC News

Just about everyone must now be aware of Pope Frankie's loudly proclaimed determination to reform the Catholic Church and put a stop to the multiple child abuse scandals that were costing it money and members. No longer are these habitual abuses, routine cover-ups and tacit approval of them to be tolerated, so the way the church dealt with the latest child abuse scandal should come as no surprise.

When the Vatican heard that yet another Catholic priest was under investigation by the Canadian Police for child pornography offences, it lost no time in dealing with the matter in the interests of all concerned.

Modern humans may have been around for nearly twice as long - Uppsala University, Sweden

More evidence today of modern humans emerging gradually from archaic hominins in Africa.

This genetic and archaeological analysis by a team from Uppsala University, Sweden, and the University of Johannesburg, South Africa, suggests, contrary to accepted wisdom, that modern humans may have diversified from archaic forms significantly earlier than generally believed and maybe not in a single location from a single founder species.

The suggestion is that anatomically modern humans could have gradually diversified in different African regions, then gene flow between the emerging groups produced the single, genetically diverse, species we now recognise as Homo sapiens.

This new study has been made possible by improved DNA extraction techniques which are revolutionising archaeology and evolutionary biology.

Women! For Pity's Sake Don't Drive!

Saudi Arabia's ban on women driving must remain because they ‘lack the intellect’ of men, says leading cleric | The Independent

Women should not be allowed to drive cars because, at the best of times, they have only half the intellect of men and, when they go shopping, this falls to only a quarter!

This comes on the authority of Saudi Arabian cleric and head of the Saudi government's religious edict authority in the southern province of Assir, Sheikh Saad al-Hajari.

St Francis' Bread - Such Big Claims; So Little Evidence.

On the Authenticity of a Relic: An Archaeometric Investigation of the Supposed Bread Sack of Saint Francesco of Assisi | Radiocarbon | Cambridge Core

To read the headlines, you might be tempted to believe a miracle has been prove true by scientists.

What's been proven, if anything, is just how little evidence is needed before the promoters of religious superstitions start to proclaim proof.

The mythical miracle this time is one I confess I had never heard of and about which the details, as with all the best of miracles, is sadly in very short supply. It is the 'miracle' of St Francis of Assisi's bread which, in 1224, so the story goes, a sack-full of which appeared on the doorstep of the Franciscan Friary of Folloni in southern Italy, so saving the brothers within from starvation, the friary being cut off by snow.

Doing the 'Impossible': Recycling Old Genes

Humans and fish share about 70% of their protein-coding genes, but only about 0.5% of their regulatory long noncoding RNAs (lncRNAs)
Genomic Recycling: Ancestral Genes Take On New Roles

And another sacred creationist dogma crashes and burns.

Imagine! You're a creationist fraud trying to make an even better living by taking yet more money off people who feel so important that they believe they must have a close personal relationship with the creator of the Universe! You're feeding them all sorts of sciencey-sounding stuff because, despite convincing them that science is all wrong, they still have a nagging doubt that it might not be, so, to be on the safe side, you want them to think that even if it is right occasionally, it supports their preconceived ideas and confirms that they know better than all those wacky scientists.

Declining Christianity in USA

America’s Changing Religious Identity:

A major new report published today by PRRI has revealed a continuing decline in religious affiliation with 'nones' now comprising 24% of the population.

There is now a marked generational shift in religious affiliation with 38% of the key 18-29 year-old age group identifying as 'nones' against just 12% for the 65+ age group. White Christians now comprise just 24% of the 18-29 year-olds against 63% of the 65+ age group.

The report also reveals the continuing decline in White Christians who fall below 50% for the first time in a PRRI survey, although other surveys have also reported a similar recent finding. This group, which in 1976 comprised 81% of all American adults, now accounts for just 43%.

Two other significant findings were the increasing ethnic transformation of American Catholicism which, 25 years ago was 87% White, compared to 55% today, and the increasing polarisation of American politics on religious grounds. 73% of Republicans are White Christians compared to just 29% of Democrats. A decade ago, 50% of Democrats were White Christian.

Religious Belief in UK Continues to Plummet!

British Social Attitudes: Record number of Brits with no religion.

The catastrophic (from the point of view of those who earn their living from it) decline in religious belief in the UK continues apace according to the authoritative British Social Attitudes Survey. 'No religion' has rockets by 5% in just one years, from 48% in 2015 to 53% in the latest (2016) survey.

More than half (53%) of the British public now describe themselves as having “no religion”, up from 48% in 2015. The proportion of non-believers has increased gradually since the survey began in 1983, when the proportion saying they had no religion stood at 31%.

Church of England decline continues
The decline in religious affiliation is hitting the Church of England particularly hard. Just 15% of people in Britain consider themselves Anglican, half the proportion who said this in 2000.

The proportion of non-believers has risen from just 31% in 1983 when the survey began.

One again the church of England has seen the biggest decline and has now fallen to 15%; half what it was in the year 2000. By contrast, the proportion of self-identified Catholics has remained stable at around 5%. Other religions account for a further 6%.

The fall in religious affiliation has been driven mostly by a decline in the proportion of 18-24 year-olds identifying with a religion, but there was a decline in all age groups between 2015 and 2016. 'No religion' in the 18-24 year-old age group increased to 71% from 63% in 2015; a stunning 8% rise in a year! In this group, Anglicans now comprise just 3%.

Frog Shocker!

New study contradicts assumption that true frogs diversified as they expanded their range around globe | The University of Kansas

One of the nice things about science is that, properly done, it can throw up some surprises, even overthrowing some preconceptions and axioms.

Science demands we constantly question and reassess our assumptions and preconceptions. It is not for those who prefer simple certainties over difficult truths.

For example, it is generally assumed that when a species colonises new geographic regions with new ecological niches, it will tend to adapt and radiate into several new species; that range extension itself is a major driver of speciation.

But this is not always so, it seems.

Papua New Guinea Missed The Flood?

Each language group is represented by a circle; the area indicates the number of genotyped individuals, and the color indicates the top-level language phylum. The study found that people speaking different languages were strongly genetically distinct from each other.

It's just another of those pieces of information that creationists have to avoid, of course, but the people of Papua New Guinea have been isolated from the rest of the world for 50,000, and people in some mountain valleys have been isolated from their neighbours for 10-20,000 years!

So, if you subscribe to the Young Earth Creationist superstition, these people are much older than Earth, have been isolated since before Adam and Eve, and appear to have avoided the Biblical flood entirely.

Yes! It is a silly superstition, isn't it, yet some apparently otherwise normal adults believe it!

Anyway, back to reality.

Using song playback experiments to measure species recognition between geographically isolated populations: A comparison with acoustic trait analyses | The Auk

An interesting piece of research published yesterday shows how birds use song to recognise members of their own species, so avoiding hybridisation between closely related species, especially when there is little or no difference in appearance.

The researchers believe they have identified 21 new species of bird from Central and South America in the 72 related populations examined where different songs effectively produce isolated breeding populations.

Just Another Child Abuse Scandal.

Smyllum Park, Lanarkshire, as it appears today.
Hundreds of Scottish orphanage children allegedly buried in mass grave | UK news | The Guardian

Normally, when people talk about systematic, institutionalised child abuse, we think of priests and male teachers abusing vulnerable children in their care or over whom they have trusted authority. It speaks of the sheer volume of these cases that yet another exposure barely rate a mention in the news any more. It's as though we have come to expect men of the cloth to abuse their power for their own gratification.

But, despite the documented abuses in Ireland and Spain where it was nuns, sometimes with the connivance of priests, who were doing the abusing, it still comes as something of a shock when we hear of female clerics abusing children. Somehow it seems even sicker when a supposedly maternal female is looking at children as a source of amusement and sexual or sadistic gratification, yet these cases seem to have been no less prevalent in institutions where nuns were in similar positions of power over children as are the abusive priests.

Today, we have another shocking example.

Snake Evolution in Progress

Arguably the most attractive British snake of the three native species, and certainly the largest, is the grass snake.

Now it seems, according to a paper published in Scientific Reports a few days ago, it is the Western representative of what is an example of speciation in progress. It also illustrates the conflict between genetics and taxonomy.

Six Million Year-Old Cretan Footprint Problem - For Creationism!

Six Million-Year-Old Human Footprint Discovered in Crete Raises Major Questions About Our Evolution

A neat illustration this week of how the popular media distort and misrepresent science in order to appeal to a wider audience and in doing so, feed and reinforce popular misconceptions.

First, we have MSN news announcing that six million year-old human footprints have been found in Crete. This then, of course, is presented as raising 'major questions' about our evolution. Creationists groups on Facebook and elsewhere are already full of claims that this proves science has got everything about evolution all wrong, either neglecting the six million years of explaining them away as proving science even gets the dating wrong.

The source of this story was the press release from Upsala University, Sweden, which announced the publication of a paper by a team based there. Unlike the MSN headline - "Fossil footprints challenge established theories of human evolution" - the headline on this press release was more muted (and of course more accurate). No mention of human footprints there, although there was an attempt to associate the discovery with current understanding of human evolution.

But what understanding was challenged, exactly?
