Wasps and the Evolution of Language

Just like living things, language evolves - and sometimes in the same way. When a population splits into two isolated groups, both evolve differently. *

In the 11th century, the modern French word guerre was pronounced gwerra. When the word arrived in England (courtesy of the Norman invaders after 1066), it was effectively isolated from the original language 'population' among British speakers who learnt French. The word mutated and lost the G so we pronounced it, after a few more mutations, as war. Roughly: gwerra to werre to war. Dropping the E on the end of the word is a common mutation.

Mediaeval scribes often used signs as shortcuts. In the 11th century, the word for school was written and pronounced escole (compare with escuela in Spanish, also a Romance language - which means derived from Latin). Later, it was written with an accent at the start as a scribes' sign that there was an S after the E . It's now written école and the S has been dropped from pronunciation. But before that happened, it came over here as escole, from which we got school.

The circumflex was a scribes' sign with a similar purpose, for example hôpital and forêt were pronounced hospital and forest.

People in some parts of France, like Paris, sound the E on the ends of some words as a short UH as in uh-huh. More technically it's called a schwa. So école would be écol - uh.

In the 12th century, the modern French word guêpe was written guespe and pronounced gwesp. The English mutated it by dropping the G and pronounced it wesp and then wasp.

Sometimes words split into further separate speaker populations after the initial isolation to create a kind of sub-species. In some parts of England like the West Country where I'm from, the G of guespe didn't die off but the W did. As G is not hard when followed by E (as in gesture) and the final E of guespe was sounded as a schwa, pronunciation went gwesp - jesp- jespa and that's why we yokels call wasps jaspers.

What the connection is with the old song 'Oh Sir Jasper do not touch me' is not known.

The Death of Atheism?

Atheists are breeding themselves out of existence. Or rather, not breeding. The religious, meanwhile, have evolved to go forth and multiply - according to the media.

The first round of 'news' stories was based on a paper called The Reproductive Benefits of Religious Affiliation by Michael Blume. The story has now come back because of a paper by Robert Rowthorn: Religion, fertility and genes: a dual inheritance model

Blume says that religious people have evolved to produce more children than the non-religious, even in developed countries (he cites Switzerland as an example). He suggests that this is because belonging to a religious community provides more co-operation in child-rearing and that such communities particularly benefit women of reproductive age as religion promotes marriage and fidelity.

This got reported (for example in the Sunday Times) as 'over evolutionary timescales of hundreds or thousands of years, atheists had fewer children and the societies they belong to are likely to disappear'.

Evolutionary timescales are rather more than hundreds of years - unless you're a fruit fly. The reporting ignores many other key factors. For example, most atheists have religious parents, they don't just spontaneously generate. There are more openly atheist people now than there have ever been. Figures on church attendance, religious affiliation and belief in the UK, for example, showed a marked decline in younger people - who have yet to breed.

However, in many societies, it is still hard - even dangerous - to be openly atheist; social traditions that encourage and facilitate large families are likely to influence even non-believers who live (covertly) in them. The Atheist Doomsday scenario also ignores the fact that in third world countries, people have more children regardless of their religion because they are needed to work to support the family and because more children die young. The research looks only at birth rates, not long-term survival rates. While a country's religion may encourage this kind of breeding, there are many more factors than faith.

The reporting also assumes that the current geo-political and religious status quo will hold for long enough into the future for evolution to have an effect and for atheists to be wiped out. Moreover, religion may apparently encourage fidelity but human nature is sneaky just like all animal nature. Believers were delighted with March of the Penguins as it appeared to show faithful penguin couples - except they're not. Just like many other animals, penguins have evolved to be opportunistic and will sneak off for some extra-conjugal mating whenever they get the chance. If the punishment for being caught is high (like stoning, say), this may deter some but will just increase ingenuity in others who will pass on the sneaky gene to their children...

Furthermore, how many atheists were there even 2000 years ago let alone 100,000? Without knowing this, we can't even begin to look at any possible evolutionary effects. There was no non-believing control group in the Iron Age.

The Telegraph version of Robert Rowthorn's paper is 'Believers' gene will spread religion, says academic'.

Except he doesn't. Rowthorn posits various possible scenarios. One is that religion becomes more widespread because religious people breed more so the genetic propensity to believe and breed spreads. He mentions the Blume study. But in that study, religiosity is measured by attendance. This may work in most current Western cultures but in some parts of the world, non-attendance is almost impossible because of social pressures. Similarly, in Elizabethan times, it was illegal not to go to church so by that measure, everyone was religious.

In addition, Rowthorn says that 'heritability studies suggest there is currently significant variation in genetic predisposition towards religion'. So not all religous people are equally religious although he does assume that 'all religious adults... have the same fertility irrespective of their genes', which is quite a big assumption.

Another scenario is that religions where people do not marry out will continue to breed at a much faster rate than the rest of the population - he cites the Amish and Haredi Jews as examples. However, Rowthorn points out that while they could vastly increase their numbers, as groups grow, the chances of defection increase as members are more likely to come into contact with outsiders and because it is harder to control larger groups. As people from third world countries move to the West, there will be economic restraints on having very large families to factor in.

He doesn't look at the problems of inbreeding in such groups, which may reduce survival fitness as harmful mutations spread.

Finally, he posits a scenario where defectors from religions take their religious genes with them. Presumably these are the weaker variants or people wouldn't be able to lose their religion in the first place. Going with his argument, these defectors will take their genes into the general population where they will manifest themselves in secular ways, for example as a respect for authority. He doesn't consider, for example, the fact that some defectors leave because they are gay and can live openly in mainstream society. The likelihood of them breeding is considerably reduced (although not eliminated).

Two rather over-simplified papers base their findings on very narrow parameters and assumptions, ignore complicating factors and other potential influences (culture, economics for example) even though genes never work in isolation but in tandem with the environment. They are reported as heralding the death of atheism.

It's true that some developed countries are producing fewer children. Just to muddy the waters, the birth rate in Italy and Ireland, strongly Catholic countries, is also falling as people ignore the priests and control their fertility.

While some religious groups in this country might be only too happy to see the death of the 'Dawkins' gene, they might also like to consider the scare stories about how Muslims will out-breed all other groups in Europe. Not so smug now, then.

Religion On My Mind

The Telegraph has a story today about how the human brain is hard-wired to believe in God.

This isn't news. However, George Pitcher, the Telegraph's religion editor and an Anglican priest at St Bride's Fleet Street, is claiming that research on the subject has 'made religious faith feel normal for once' and that it shows religion 'makes us perform better'.

He is overlooking a few inconvenient facts. He mentions Professor Bruce Hood's research but can't have read it very thoroughly. Hood, and other writers like Pascal Boyer, Marc Hauser, Paul Bloom and Matt Ridley, have made it very clear that religion is a side-effect of the brain's evolution.

You could equally well say that we have evolved the ability to read and write, to find flowers pretty, to believe in horoscopes and ghosts, to be vulnerable to malaria and to be heroin addicts. All of these are side-effects. Not all side-effects are beneficial; picking one that suits your argument is lazy. As is ignoring the bad effects of religion or blaming them on some other cause.

There is no evidence that the brain has evolved to believe in the Christian god in particular, so believers can't use this factlet to justify their own belief as the only right one any more than a belief in Zeus, Ra or Thor. And even if we had evolved to believe in a certain god, that doesn't prove that he or she exists any more than believing that horoscopes are true makes them so. It's wishful thinking.

Hood and others like him are not 'promoting' religion as Pitcher suggests. They are investigating why this particular evolutionary spandrel has proved so tenacious.

As we all have common ancestors, why do some of us not believe in any god or other superstition? This is a question that needs to be answered by scientists and by believers using a mis-reading of evolution to bolster their faith.
