Who dares to query evolution?

This is a good statement of why someone can dare to query macro evolution.

PAGE THIRTY-TWO: Maths and Science

What did the Arts graduate say to the Science graduate?
"Do you want fries with that?"

I was firmly in the humanities mould. I coped with Arithmetic pretty well in primary school (but still don't know why they marked it out of 200 and everything else out of 100), but didn't do nearly as well in high school. My marks were quite reasonable, but not near the top of the class as they had been.

I found the geometry theorems interesting, and enjoyed the pun which my father told me, when he said that Q E D, written at the end of a proof, signifying quod erat demonstrandum (which was to be proved), also stood for Quite Easily Done.

We had a good Maths teacher from first to fourth form: Mr Steinmetz, whose hair had gone prematurely white. He was a kind, but no-nonsense sort of man.

My three high school Maths teachers are in this photo. Mr Steinmetz is the white-haired man in the back row. My teacher when I was in fifth form was Paul Danks, the young man on the left in the back row. When we got to sixth form, my teacher was John Sheriff, the bespectacled man in the middle of the front row.

Boys in my fifth form class gave our new teacher a hard time, and used to mimic the opening music from the 1950s Dragnet TV series when he entered the room:
And some also used to play table tennis at the back of the classroom, while the lesson was in progress, using black gloomy-looking Maths textbooks for bats and net.

Maybe that's why our teacher in sixth form was the Maths master, John Sheriff. He didn't like students mindlessly copying things from the blackboard while he was speaking.

When we were at school, blackboards were actually green, but they were most certainly chalkboards. However, towards the end of my time in high school,  the Music classrooms had whiteboards and textas, so that the chalk would not get into the gramophone records.

But Mr Sheriff's solution was to make us put our pens down and watch and listen. Then, after he had demonstrated his point, he would rub the material off the blackboard, and then tell us to write it down!

Although I had a better memory then than I have now, I missed quite a bit, and had to buy a book of formulae to get me through 2S Maths.

John Sheriff became deputy headmaster of Warner's Bay High School, when Margaret and Kevin's children Jamie and Tammy were there. The students used to love singing
I shot the sheriff
But I did not shoot the deputy
which they knew from the Eric Clapton version of Bob Marley's song.

I was even worse at  Science than I was at Maths, and was demoted to 3B, in 1967. Oh, the ignominy!
Our teacher was Bob Horne. He was young then. He enjoyed geology, but I found it thoroughly boring. Mr Horne's Science experiments never seemed to work. After each failure, he would say, "Well, this is what was supposed to happen."

But, on one memorable day, an experiment worked. He was demonstrating the displacement of water, and when he put a rock into a beaker of water, voilĂ ! The water rose.

He used to enjoy goading the Christian students. We were firmly against evolution in Belmont Baptist Church, and one of the girls told the teacher she didn't believe in it. This was like a red rag to a bull, and Mr Horne invited God, if he existed, to strike him dead. Amazingly, the Almighty didn't let our teacher set his agenda, and Mr Horne survived.

I didn't do Science in fifth or sixth form, and studied Music privately, doing the AMEB HSC course, which involved doing Seventh Grade practical and Sixth Grade theory. I think my piano teacher, Miss Keeley supervised my Sixth grade theory. Don't tell my Music Craft students at Mitchell Conservatorium, but I only managed a credit!

Charles Darwin and the Children of the Evolution

TIMES ONLINE has a fascinating account of some of Darwin's other ideas, often linked to his big idea, and the way that some psychopaths have eagerly adopted them.
The naturalist outraged the church, prompting a bitter debate that still sets creationists against evolutionists. Now a sinister link has emerged between his work and the recent spate of high-school killings by crazed, nihilistic teenagers.

You wouldn’t know from the celebrations of Charles Darwin’s life this year that the amiable Victorian gent portrayed in those TV drama-docs pottering around the garden of his home in Kent has been fingered as a racist, an apologist for genocide, and the inspiration of a string of psychopathic killers.

The Darwin double anniversary (2009 marks both the bicentenary of his birth and 150 years since the first publication of On the Origin of Species) has featured much vanilla hoopla: the Royal Mail issued commemorative stamps; Damien Hirst designed the dust jacket for a special edition of Darwin’s masterpiece; Bristol Zoo offered free admission to men with beards, and the Natural History Museum served pea soup made to a recipe devised by Darwin’s wife, Emma. The conclusion of dozens of lectures, articles and education packs for schools has been that Darwin wasn’t just a brilliant scientist, but a thoroughly good egg.

With hardly a mention that his name has been associated with some of the most infamous crimes of modern history, it is as if there has been an unspoken agreement to accentuate the positive. Certainly, the milquetoast Darwin played by Paul Bettany in the recent film Creation provided little hint that there might be a dark side to the great man’s bequest to posterity. The film focuses on Darwin’s inner conflicts in the years leading up to the publication of On the Origin of Species. The scientist is reluctant to make his ideas public, not because he has foreseen dire social consequences, but chiefly because he fears that the theory of evolution will upset his wife and the Church of England.

In America, where Darwin’s writings on morality and race have come under particularly intense critical scrutiny because of the enduring creationist debate, he has been accused of fostering moral nihilism and scientific racism, and even of promoting an ethic that found its ultimate expression in the Holocaust. Most startling of all, a connection has now been drawn between Darwin’s theories and a rash of school shootings. In April, 1,000 people gathered at sunset in Littleton, Colorado, to commemorate the victims of the Columbine high school massacre, 10 years on. Darrell Scott, whose daughter Rachel was the first of the 13 children to be murdered, and whose son Craig narrowly escaped being shot, cannot understand why so little attention has been paid to the motivation of the killers, Eric Harris and Dylan Klebold, and their interest in Charles Darwin’s ideas. “Harris wore a ‘Natural Selection’ T-shirt on the day of the killings. They made remarks on video about helping out the process of natural selection by eliminating the weak. They also professed that they had evolved to a higher level than their classmates. I was amazed at the frequent references to evolution, and that the press completely ignored that aspect of the tapes.”

Much of the evidence remains sealed under a court order issued to minimise the risk of copycat killings, but from those documents that are in the public domain, it is clear that Eric Harris fantasised about putting everyone into a violent computer game that only the fittest could survive. And, like Darwin himself, he noted how vaccination might be interfering with nature’s weeding process. In his rantings Harris said he wished there were no vaccines, or even warning labels on dangerous goods, “and let natural selection take its course. All the fat, ugly, retarded, crippled dumbass, stupid f***heads in the world would die… Maybe then the human race can actually be proud of itself”.

As the attorney for the families of six of the students killed at Columbine, the Denver lawyer Barry Arrington has come across more in a similar vein. “I read through every single page of Eric Harris’s journals; I listened to all of the audio tapes and watched the videotapes… It became evident to me that Harris consciously saw his actions as logically arising from what he had learnt about evolution. Darwinism served as his personal intellectual rationale for what he did. There cannot be the slightest doubt that Harris was a worshipper of Darwin and saw himself as acting on Darwinian principles.”

In 2007, detectives following up a tip-off about a planned school shooting in Pennsylvania discovered that their suspect often logged on to a social networking site called Natural Selection’s Army and a number of related chatrooms that were later tagged by the media as the “cyber school for killers”. These sites were quickly shut down by their service providers, but today “Natural Selection” is the name of a popular computer game in which competing teams attempt to annihilate one another — a sign that Darwin’s term is still associated by many teenagers with sudden and extreme violence.

“Natural Selection” T-shirts have proved a popular line through web-based outlets, and it seems that the Columbine killers have spawned a gruesome personality cult — there is even a computer game in which players adopt the roles of Harris and Klebold, which features original CCTV footage of the killings.

Among those reported to have frequented the original Natural Selection’s Army website was an 18-year-old Finnish student, Pekka-Eric Auvinen. On November 7, 2007, in Tuusula, Finland, Auvinen forced his head teacher to kneel down in front of him before he shot her with his pistol. He slaughtered a further seven victims before turning the gun on himself. Some of the Jokela high school students afterwards described the way Auvinen prowled through the building pointing his gun at people’s heads. Sometimes he would squeeze the trigger and kill them; sometimes, after looking long and hard through the sights, he would suddenly turn away and let his terrified target go free. One witness said he seemed to be choosing his victims at random, but in fact he was making a very deliberate selection. He was trying to weed out the “unfit”.

Before he embarked on his shooting spree, Auvinen posted a lengthy apologia on the internet. Styling himself a “social Darwinist”, he said that natural selection appeared not to be working any more — had maybe even gone into reverse. He had noticed that “stupid, weak-minded people reproduce faster than intelligent, strong-minded ones”. The gene pool was sure to deteriorate if society continued to guarantee the survival of the second-rate. He had pondered what to do about this problem. He understood that life was just a meaningless coincidence, the outcome of a long series of random mutations, so there might not be much point in doing anything at all. But eventually he had decided he would do his bit by becoming a natural selector, aping the pitiless indifference of nature.

Auvinen left a special plea for his motivation to be taken seriously and for the world not merely to write him off as a psychopath, or to blame cult movies, computer games, television or heavy metal music, before concluding: “No mercy for the scum of the Earth! Humanity is overrated. It’s time to put natural selection and survival of the fittest back on track.”

Of course, it is not unusual for homicidal maniacs to cite great writers when seeking to justify their crimes. The Chicago spree-killers Leopold and Loeb (the models for Hitchcock’s 1948 film, Rope) claimed Friedrich Nietzsche as their muse, as did the Moors murderer Ian Brady. Other deranged misfits have nominated Albert Camus, Jean Genet and AndrĂ© Gide. But it may take a keener intellect than was possessed by Harris, Klebold or Auvinen to negotiate such a reading list. The basics of evolution are much more accessible and are taught in every high school, so it should not be surprising that Darwin seems to be emerging as the inspiration for the more dim-witted schoolboy sociopath.

Darwin would no doubt have been horrified by all this, but it’s easy to see why some of his ideas might appeal to the disturbed adolescent mind. One conclusion implicit in evolutionary theory is that human existence has no ultimate purpose or special significance. Any psychologically well-adjusted person would regard this as regrettable, if true. But some people get a thrill from peering into the void and acknowledging that life is utterly meaningless.

Darwin also taught that morality has no essential authority, but is something that itself evolved — a set of sentiments or intuitions that developed from adaptive responses to environmental pressures tens of thousands of years ago. This does not merely explain the origin of morals, it totally explains them away. Whether an individual opts to obey a particular ethical precept, or to regard it as a redundant evolutionary carry-over, thus becomes a matter of personal choice. Cheerleaders celebrating Darwin’s 200th birthday in colleges across America last February sang “Randomness is good enough for me, If there’s no design it means I’m free” — lines from a song by the band Scientific Gospel. Clearly they see evolution as something that emancipates them from the strict sexual morality insisted upon by their parents. But wackos such as Harris and Auvinen can just as readily interpret it as a licence to kill.

The American conservative controversialist Ann Coulter is one of Darwin’s fiercest critics, lambasting him in her book Godless and via cable TV. Coulter claims she is not surprised that psychopaths gravitate towards Darwin’s ideas. “Instead of enshrining moral values,” she says, Darwin “enshrined biological instincts.” Coulter believes Darwin’s theory appeals to liberals because it “lets them off the hook morally. Do whatever you feel like doing — screw your secretary, kill Grandma, abort your defective child — Darwin says it will benefit humanity”.

Today’s evolutionary scientists go some way towards Coulter’s view when they describe ethics as merely an illusion produced by genes. From a Darwinian perspective, there is nothing objectively wrong with shooting your classmates; it’s just that most of us have an inherited tendency to kid ourselves that it’s wrong — and that’s something that helps our species in the longer run by keeping playground massacres to an acceptable minimum.

Darwin looked forward to a time when Europeans and Americans would exterminate those he termed “savages”. Many of the anthropomorphous apes would also be wiped out, he predicted, and the break between man and beast would then occur “between man in a more civilized state, as we may hope, even than the Caucasian, and some ape as low as a baboon; instead of as now between the Negro or Australian and the gorilla”. He took a sanguine view of genocide, believing it to be imminent and inevitable. “Looking to the world at no very distant date,” he wrote to a friend in 1881, “what an endless number of the lower races will have been eliminated by the higher civilized races throughout the world.”

Convinced that the various races of mankind had travelled different distances down the evolutionary highway, and that two races could be fairly described as more or less evolved even when both had a track record of cultural achievement, Darwin insisted that natural selection explained why the Europeans had been able to see off serial invasions by the Ottoman Turks. Some of today’s Turks understandably resent being designated as genetically second-rate, which perhaps explains why the editor of Turkey’s most popular science magazine was instructed by his proprietor to cancel a special edition celebrating Darwin’s anniversary.

For many years after his death, Darwin’s racial theories remained the consensus position of the international scientific community. In 1906, the director of the Bronx Zoo decided to give New Yorkers an object lesson in human evolution by putting a 23-year-old Congolese pygmy on public display in his monkey house. The pygmy, Ota Benga, shared his cage with an orang-utan. The spectacle drew enormous crowds. Before long, they were asking the questions the exhibitors hoped they would: was Ota Benga an ape or a man? Or, as the zoo-keeper himself speculated, was this perhaps a transitional form between the two, the elusive missing link?

When a group of African-American clergymen objected to a human being being put on show, they were told that Darwin’s theories were now accepted scientific facts, that the “lower races” were psychologically closer to pigs and dogs than to human beings, and that a different value should be put on their lives. Truths that the founders of the United States had held to be self-evident — that all men are created equal and had certain inalienable rights — were being denied by the promoters of Darwinian science. By the end of the first world war, it was not only blacks who were deemed genetically inferior by many of America’s top geneticists and biologists, but Italian, Greek and Jewish immigrants too.

In their book Darwin’s Sacred Cause, Adrian Desmond and James A Moore argue that, far from nursing racial prejudices, Darwin was driven to advance a theory of common descent by his hatred of slavery. But how can the idealistic abolitionist be reconciled with the man who so casually contemplated the extermination of entire races? Some argue that he grew more racist as he got older; others that his racism followed logically from his theories.

Nowhere was the toxic doctrine of racial superiority more enthusiastically taken up than in the Third Reich. The Nazis believed that the Aryan race was already the most highly evolved, but could evolve further if defective genes could be eliminated. To purify the German gene pool, they decided to exterminate all the physically and mentally handicapped.

Darwin summed up his moral philosophy by saying that a man could “only follow those ideas and impulses that seem best to him”. Darwinian ideas, eugenics and its ugly sister, eugenic euthanasia, were accepted by the mainstream of the German scientific and medical professions. Indeed, so convinced were the staff of the clinic at Kaufbeuren-Irsee in Bavaria that they were acting rationally that, even after Germany’s surrender in 1945, they carried on killing handicapped people under the American occupation, until a US officer led a squad of GIs to the hospital and ordered them to desist.

The connection between Darwin’s ideas and the Holocaust remains hugely controversial, not least because many creationists try to reduce it to a crude blame game. The writer David Klinghoffer, an advocate of intelligent design, which many regard as creationism in disguise, claims: “The key elements in the ideology that produced Auschwitz are moral relativism aligned with a rejection of the sacredness of human life, a belief that violent competition in nature creates greater and lesser races, that the greater will inevitably exterminate the lesser, and finally that the lesser race most in need of extermination is the Jews. All but the last of these ideas may be found in Darwin’s writing.”

The debate between Darwin’s bulldogs and religious fundamentalists over the truth of evolution and the existence of God has become a sterile one. There are, however, many interesting questions about how Darwin’s views chime with our values of liberal democracy and human rights, or the simple lessons of right and wrong that most of us teach our children. But our society cannot begin to address these issues while we are fed only a bowdlerised account of Darwin’s work. The more sinister implications of the world-view that has come to be called “Darwinism” — and the interpretation the teenage nihilists put on it — are as much part of the Darwin story as the theory of evolutions

Why not every scientist worships at Darwin's feet

This is an excellent piece in today's SMH.

The writer is John Lennox, who is a visiting scholar of The Centre for Public Christianity.

I thought his last three paragraphs were particularly good:
One scientist views images captured by the Hubble telescope of the unimaginably large scale of the universe and remains convinced of the random nature of a godless existence. Another stares through a scanning tunnelling microscope at the unimaginably small and complex entities of molecular biology and feels compelled to worship the creator. It isn't the science itself that is definitive for the question of the divine.

The late evolutionary biologist Stephen Jay Gould wrote that science simply cannot "adjudicate the issue of God's possible superintendence of nature". For Gould, it was a mistake to apply scientific principles to questions of metaphysics.

In 2009, when the champagne is uncorked in celebration of Darwin's legacy, we might pause to consider the presuppositions we bring to the question of what his theory tells us about God. There are essentially only two options. Either the wonder of human intelligence ultimately owes its origin to mindless matter; or there is a creator. It remains a mystery to me why some people claim it is their intelligence that leads them to prefer the first to the second.

I also thought this was worth reporting:
Scattered among the world's top scientists are those who do believe in a conscious intention behind nature's processes. I think of people such as Francis Collins, director of the Human Genome Project, and Professor Bill Phillips, winner of the Nobel Prize for Physics in 1997.

Indeed, the fact that there are brilliant scientists who believe in God and brilliant scientists who don't makes it clear that the conflict is not a simplistic one between science and religion, but between opposing world views - naturalism and theism.
