Following close on the news that creationism's malevolent... er... sorry... intelligent (sic) designer has designed liver flukes to be better at making us and our livestock sick, comes news of another brilliant piece if design to improve a mosquito's ability to give us serious infections with life-threatening parasites.

Researchers from the Department of Biological Sciences & Biomolecular Sciences Institute, Florida International University, Miami, FL, USA have shown how the antennae of female Aedes aegypti Mosquitoes can 'smell' characteristic signature chemicals in human body odour. Their findings were published open access in Current Biology yesterday.

Malevolent Designer News - Making a Better Liver Fluke

Scientists working at the University of Córdoba, Spain, have discovered just how devious any intelligent designer would have to have been when it designed the liver fluke, Fasciola hepatica.

Creationists who advocate intelligent design as the best explanation for organisms and the diversity of living things need to believe several key things about their purported designer:

Catholic Bishops Admit Bible Class Disadvantages School Children

Richard Brunton, TD.
In Letter to Irish Government, Bishops Admitted Religion Makes Kids Dumber | Hemant Mehta | Friendly Atheist | Patheos

In an astonishing letter to the then Irish Minister for Education and Skills, Richard Bruton, TD PDF, Catholic bishops have unwittingly revealed that even they regard religious education as detrimental to the children being subjected to it.

The letter, which had never been made public, came to light by chance when Seamus and John from The Free Thought Prophet Podcast were researching for a podcast and submitted a Freedom of Information request to the Irish Department of Education and Skills.

The letter was written in response to Circular Letter 0013/2018 PDF from the Department of Education and Skills, detailing proposals for changes in the purpose of the circular was to:

... set out a new approach to the arrangements that are made for religious instruction and worship in the schools covered by this circular in order to ensure that the rights of children to attend the school without having to attend religious instruction will be conducted in a manner that takes account of the likelihood, given changing demographics, of an increasing number of families wanting to exercise their constitutional right to withdraw.

Sri Lanka and New Zealand - Why the Different Responses?

In a world in which we've become used to mass killings and atrocities by religious fanatics, often perpetrated against members of a different religion, the New Zealand atrocities carried out by one fanatical Christian against Muslims peacefully at prayer stood out for it's barbarity and brutal violation, not just of the lives destroyed but of a peaceful and tolerant society.

The death toll was 50. People across the world were rightly outraged by it.

In Sri Lanka, an as yet unidentified (but assumed to be Muslim) group yesterday targeted Christian churches with bombs designed to kill as many as possible while Christians were at prayer on a day which many Christians regard as the most holy of the year.

Also targeted were hotels where mostly Europeans stay in a country in which Europeans are assumed to be Christian. This was clearly an attack against members of a religion by members of a different one.

The death toll currently stands at about 300. And yet the response to the Sri Lanka massacre has been far more muted than the response to the New Zealand massacre.

Moral Decisions - No Gods Required

How Do We Make Moral Decisions?

Contrary to Christian apologists' assertions, humans do not get 'objective' morals from a god whose capricious whims determine right and wrong.

No matter how much C.S.Lewis tied himself into knots with his intellectual contortions, trying to prove that because he couldn't tell right from wrong, the god his mummy and daddy believed in must be real, the evidence of other cultures with other gods, and with none, shows that moral codes have broad principles common to all human cultures.

The rule probably most basic to all human cultures is the 'golden rule' - do as you would be done by or, as Christians would say, do unto others as you would have them do unto you. However, why people generally stick to this principle has been the subject of debate. Do they do it because of guilt, because we would feel bad about letting the other person down, or because of an innate sense of fairness where we want the fairest outcome.

Far from being, as creationists would have their duped believe, a theory in crisis, evolution is so well embedded as a fundamental science that no serious scientists even question it any more, that it can be used to settle debate about things like climate change and distribution of different biomes in the past.

An example of this is the paper in Molecular Phylogenetics and Evolution in which the distribution of a family of oven birds in the Amazon and Andean rain forests was used to show how and when these two rainforests were connected at times.

Fall in US Religious Affiliation is Accelerating

U.S. Church Membership Down Sharply in Past Two Decades.

A second poll in a few days has confirmed the sharp, and accelerating, decline in religious affiliation in the USA. Now only 50% of Americans identify themselves as belonging to any particular church, synagogue or mosque, compared to 68% or more between 1937 and the 1990s.

This fell by only 2% between the 1970s and 1990s, but in the last 20 years the decline has accelerated massively to 20% with more than half of that in the ten years up to 2018. Projecting this accelerating trend forward, religious affiliation in the USA should be below 30% within the next 15-20 years.

Notre Dame - Not Just a Catholic Cathedral

No trip abroad or to a new city in the UK for my partner and I would be complete without a visit to the local cathedral, and so it was when we were in Paris some years ago. We put an afternoon aside for it.

The Cathedral of Notre Dame was a monument not just, or for us as Atheists even partly, to the 'Glory of God', but to to the glory of mankind's artistry and craftsmanship.

We looked upon the skill and dedication of the carpenters, stonemasons, iconographers and stained-glass window designers and creators and wondered who they were. What lives did they live? How did they get those skills? What were their thoughts as they made their mark and left a record of their existence for future generations?

The 'Nones' Take The Lead in USA

'Black Protestant' and 'Jewish' subsumed into 'Other faiths' to give 'Other affiliation'
'No religion' includes Atheists, Agnostics and spiritual but not affiliated to any religion.
Survey: As many Americans claim no religion as there are evangelicals, Catholics - CNN.

The 'nones' are winning.

Within a few days of one another, we have two major opinion surveys by respected organisation, both showing a huge and growing movement away from religious belief, especially Christianity, towards having no religion. Last week we saw a 46% increase in no belief in the UK between 2011 and 2018 and now we hear that the largest single demographic in the USA is the 'none', who have overtaken the Catholics and evangelicals for the first time.

This latter survey was released last month but has only just found it way into the mainstream news media.

Evolution in Just Six Generations

Interplay of pollinators and pests influences plant evolution

Evolution is a dynamic process in which a species responds to competing selection pressures in its environment. Some of these might push the species in one direction and others in the opposite direction. Changing environmental factors effectively redefine the term 'fitness' as it applies to relevant characteristics.

Brassica plants, for example, have large attractive flowers which attract insect pollinators. They are also monoecious or hermaphrodite and, like many plants, have both male and female parts in the same flower, so are capable of 'selfing' or self-pollination.

Pollination by pollen from other flowers, carried by pollinating insects, increases genetic mixing, so reducing the change of deleterious mutations occurring in the same individual. This pressure pushes the species towards the evolution of larger, more attractive flowers.

However, there is a price to pay in that large attractive flowers also attract herbivores that eat brassica leaves, so wasting the plant's resources and reducing their vigor. This pressure pushes the species towards less attractive flowers. This in turn reduces the likelihood of cross pollination, which pushes the species toward selfing and characteristic that make that more, not less likely.

Massive Increase in Non-Belief in UK

Number of non-religious people in Britain jumps by 46%, new figures show » Humanists UK

Figures released by the Office of National Statistic last week show that non-belief in the UK has increased by an astonishing 46% since 2011.

Over the same period, the percentage of those self-identifying as Christian has fallen by a further 15%. This is consistent with other polls that have show a sharp decline in religious affiliation and particularly affiliation to the Anglican Church whose attendance continues to fall.

However, there has been criticism, notable from Humanists UK, about the leading nature of the question asked, which significantly overestimates religious belief by tying it to religion as a cultural identifier rather than a description of actual belief.

The question asked by ONS was "What is your religion?". Other studies have shown that when people are asked, "What is your religion, if any?" they give a different answer. Subliminally, the question as asked by ONS implies the respondent is expected to have one. For example, the British Social Attitudes Survey, by using a two-part question, concluded that 52% of British people have no religious belief.

Old Blue Eyes and the Mutant Gene

Blue-eyed humans have a single, common ancestor – University of Copenhagen

Some 6-10,000 years ago, probably in the agricultural lands to the north east of the Black Sea, a person was born with strange, blue eyes. He or she was the common ancestor of all blue-eyed people alive today.

This is the conclusion of Professor Hans Eiberg and his colleagues from the Department of Cellular and Molecular Medicine, University of Copenhagen. They arrived at this conclusion after analysing the genes of a large Danish family to pinpoint the area of DNA responsible for regulating the OCA2 gene known to be the major contributor to human eye colour. This gene, HERC2 exists in a number of alleles, one of which is the mutation that causes blue eyes.

Catholic Abuse News - Indian Bishop Charged With Raping a Nun

Kerala Nun Rape Case: Franco Mulakkal Charge-Sheeted, First Bishop To Go On Trial In India For Rape

Bishop Franco Mulakkal, bishop of the Roman Catholic diocese of Jalandhar since 2013, has been charged with raping a nun nine times. This is the first time a Catholic bishop has been charged with such a crime in Indian history.

The attacks are alleged to have taken place in the southern Indian state of Karela over a two year period between 2014 and 2016. Mulakkal faces life in prison if convicted. The charge sheet includes statements from more than 80 witnesses including a cardinal, three bishops, 11 priests and 25 nuns.

He also faces charges of intimidation, illegal confinement and unnatural intercourse, charges which carry a ten year sentence.

Human Evolution News - Another New Species?

Callao Cave, Luzon, Philippines. Home of Homo luzonensis.
New species of ancient human discovered in the Philippines: Homo luzonensis

The wonderful human evolutionary story that only a few days ago became a little more complicated with the discovery of two more 'Denisovans' in Papua-New Guinea, just got even more complicated with the announcement of yet another possible species of archaic hominins on the island of Luzon in the Philippines.

A combined French, Filipino and Australian team of archaeologists led by Florent Détroit of Département Homme & Environnement, Muséum National d’Histoire Naturelle, Paris, France have discovered twelve more fragments of hominin bones and teeth to add to the metatarsal bone found in 2007 and dated to 67,000 years ago. These recent finds of two more toe bones along with seven teeth, two finger bones, and part of a femur, are from the same stratigraphic layer as the earlier find and come from at least three individuals.

Creationism's putative intelligent (sic) designer seems to have gotten itself into a right old muddle during World War I, according to the findings of a team of researchers published in Proceedings of the Royal Society B: Biological Science today.

The team from the Wellcome Sanger Institute analysed the genome of a strain of the bacteria normally responsible for causing cholera, Vibrio cholerae, isolated from a sample of the stools of a WWI soldier of the British Expeditionary Force which had been taken in 1916 while the soldier was convalescing in Egypt.

Why Christians Need to Hate Atheists

A theist comforts himself after losing another argument on the Internet.
Fox & Friends Says Protecting Atheists From Discrimination Is Anti-Christian! | Crooks and Liars

This little item by Heather from Crooks and Liars shows Christians arguing that protecting Atheists from discrimination is anti-Christian.

In other words, so they imply, to be a Christian, you should actively discriminate against people who disagree with you, or at least you should have the right to, so treating them as lesser people deserving of lower standards than you are entitled to by virtue of your religion.

None of that essential equality of man or all people being created equal stuff. That's all very well in theory and certainly applies when Christians are being discriminated against, but Atheism threatens Christianity so Christianity needs to abandon ... er... Christianity to defend itself.

So what is it about Atheism that threatens Christian fundamentalists that way? There are a couple of reasons, none of which reflect well on Christians:

Neanderthals and Mammoths Refute Creationism Again

News Page (Archaeology) - American Friends of Tel Aviv University

The news from science is never good news for creationism, but that's the problem with having opinions which are not based on reality.

This little item from Tel Aviv University, for example, shatters several creationist myths. It shows the fallacy behind the claim that all mutations are harmful and result in degradation (or 'increased entropy') in the genome. It shows common ancestry between two distantly related mammals; it shows how environmental change drives evolution and it shows how mutation does not inevitably lead to a loss of function.

Catholic Abuse News - How the Church Corrupted Ireland

Archbishop of Dublin and Primate of Ireland, Diarmuid Martin

Archbishop of Dublin Diarmuid Martin reveals paedophile priests cannot identify new victims because they abused so many - Irish Mirror Online.

The Archbishop of Dublin, Diarmuid Martin, the senior Catholic cleric in the whole of Ireland, has revealed in an astonishingly frank interview on Irish TV, that some paedophiles priests were so prolific in their abuse that when presented with names of possible victims, they could not remember, there had been so many. In some instances, their victims numbered more than a hundred.

He made the statement in an RTE program detailing the scale of the Catholic Church's interference in Irish public life, becoming involved in just about every aspect of life since the foundation of the Republic. The programme by former government minister, Michael McDowell, looks at how this situation was allowed to develop. How could an organisation with no democratic mandate, accountable only to itself and owing allegiance to a foreign state in the form of the Vatican City, wield so much power in a supposedly democratic state?

Human Evolution - More Evidence of Interbreeding

The human evolutionary story just got a lot more complicated and a lot more interesting than we thought.

Before we discovered that non-African modern humans hybridised with Neanderthals we thought it was quite straightforward. Modern humans evolved in Africa then a small group migrated out and spread all over the world.

Then we discovered the Denisovans - a different species of human that lived in Asia and with which we also interbred, making the non-African humans the result of hybridisation between three related but different species.

Catholic Abuse News - One Law for One, One Law for Another

Archbishop Anthony Apuron of Guam
Catholic Archbishop of Guam removed from office | RTE.

The Vatican is nothing if not inconsistent.

The Catholic Archbishop of the US island territory of Guam, Anthony Apuron, has been convicted by a Vatican tribunal, upholding an earlier guilty verdict by an earlier tribunal, of sexually abusing three underaged boys but is to be allowed to retain his archbishop title.

By contrast, (former) Cardinal McCarrick, Archbishop of Washington, was stripped of his title and defrocked for similar offences, and Cardinal Pell, sentenced to 6 years in prison by an Australian court for sexually abusing minors, has been presumed innocent by the Vatican, pending his appeal.
