Stephen Jay Gould, one of the great evolutionary biologists of our time, will publish his "magnum opus", this month, in which he lambasts creationists for deliberately distorting his theories to undermine the teaching of Darwinism in schools.
Professor Gould accuses creationists of having exploited the sometimes bitter dispute between him and his fellow Darwinists to promulgate the myth that the theory of evolution is riven with doubts and is, therefore, just as valid as biblical explanations for life on Earth.
The distinguished professor of zoology at Harvard University, whose 1,400-page book, The Structure of Evolutionary Theory, has been 10 years in the writing, was intimately involved with the fight against creationist teaching during the 1970s and 1980s in the American Deep South.
The arguments have resurfaced in Britain after the news that a school in Gateshead has been teaching creationism alongside evolution, arguing both are equal valid viewpoints.
Creationists still use Professor Gould's theory of "punctuated equilibrium" – which argues for the sudden appearance of new species – to support their view that Darwinism is being challenged by some of the leading thinkers in biology.
Although Professor Gould never disputed the central tenet of Darwinism, natural selection, his explanation for how new species might rapidly arise is often presented by creationists as a direct challenge to the scientific orthodoxy at the heart of Darwinism.
Evangelical creationists in particular have argued the universally accepted gaps in the fossil record and the frequent absence of intermediate forms between fossilised species are evidence that evolution cannot fully account for the diversity of life on Earth.
They have used Professor Gould's theory – which proposes long periods of stable "equilibrium" punctuated by sudden changes that are not captured as fossils – as proof that Darwinist "gradualism" was wrong and it should therefore be taught, at the very minimum, alongside creationism in schools.
Stephen Layfield, a science teacher at Emmanuel College in Gateshead, which is at the centre of the row, used the lack of intermediate fossils between ancestral species and their descendants to question Darwinist evolution.
Professor Gould says creationists have unwittingly misinterpreted or deliberately misquoted his work in a manner that would otherwise be laughable, were it not for the impact it can have on the teaching of science in schools.
"Such inane and basically harmless perorations may boil the blood but creationist attempts to use punctuated equilibrium in their campaigns for suppressing the teaching of evolution raise genuine worries," Professor Gould said.
Fundamentalist teaching reached its height in the United States in the early 1920s and culminated in the famous Scopes "monkey" trial in Tennessee in 1925 when John Scopes, a biology teacher, was arrested for teaching evolution in contravention of state law.
A second creationist surge occurred in the US during the 1970s, which led to the "equal time" laws for the teaching of creationism and evolution in the state schools of Arkansas and Louisiana. The rule was overturned in two court cases in 1982 and 1987.
At the same time, Professor Gould's theory of punctuated equilibrium was being debated among scientists. With the fellow Darwinist, Niles Eldredge, who cited the unchanging nature of Trilobite fossils in support of the idea, Professor Gould presented the theory at a scientific conference in 1971. A seminal scientific paper followed a year later.
"But I had no premonition about the hubbub that punctuated equilibrium would generate," Professor Gould said. Some "absurdly-hyped popular accounts" proclaimed the death of Darwinism, with punctuated equilibrium as the primary assassin, he says.
"Our theory became the public symbol and stalking horse for all debate within evolutionary theory. Moreover, since popular impression now falsely linked the supposed 'trouble' within evolutionary theory to the rise of creationism, some intemperate colleagues began to blame Eldredge and me for the growing strength of creationism.
"Thus, we stood falsely accused by some colleagues both for dishonestly exaggerating our theory to proclaim the death of Darwin (presumably for our own cynical quest for fame), and for unwittingly fostering the scourge of creationism as well," he said.
Not every scientist, however, would agree that Professor Gould was innocent in the dispute, which was exploited by evangelical creationists.
What was essentially an arcane argument between consenting academics soon became a public schism between Gould and his Darwinist rivals, whose position was best articulated by the Oxford zoologist Richard Dawkins.
At its most simplistic, the idea of punctuated equilibrium was presented as an alternative to the "gradualism" of traditional Darwinism. Rather than species evolving gradually, mutation by mutation, over a long period of time, Professor Gould argued they arose within a period of tens of thousands rather than tens of millions of years – a blink of the eye in geological terms.
Professor Dawkins savaged the Gould-Eldredge idea, arguing gaps in the fossil record could be explained by evolutionary change occurring in a different place from where most fossils were found. In any case, Dawkins said, we would need an extraordinarily rich fossil record to track evolutionary change.
Gould and Eldredge could have made that point themselves, he said. "But no, instead they chose, especially in their later writings, in which they were eagerly followed by journalists, to sell their ideas as being radically opposed to Darwin's and opposed to the neo-Darwinian synthesis," Dawkins writes in his 1986 book The Blind Watchmaker.
"They did this by emphasising the 'gradualism' of the Darwinian view of evolution as opposed to the sudden 'jerky', sporadic 'punctuationism' of their own ... The fact is that, in the fullest and most serious sense, Eldredge and Gould are really just as gradualist as Darwin or any of his followers," Professor Dawkins wrote.
The subtleties of the dispute were, however, lost on commentators outside the rarefied field of evolutionary theory.
It was certainly lost on many creationists who just revelled in the vitriolic spat between the leading Darwinists. (The dispute was so vitriolic it became personal – in his book, Gould relegates his critics to a section titled "The Wages of Jealousy".)
Richard Fortey, the Collier Professor of the Public Understanding of Science at Bristol University, says Professors Gould and Dawkins are closer than many people realise.
With some of Britain's leading scientists and theologians writing to the Prime Minister to voice their concerns about the teaching of creationism, the issue has come to the fore.
"It's absurd we are now facing this creationist threat," Professor Fortey said. "It's a debate that belongs to the 1840s. Evolution is not just a theory, it's as much of a fact as the existence of the solar system."
NaDene is a proposed language family, not a specific language. This illustrates why all discussions of language should be confined to professional linguists in academia, who understand its extreme subtleties, rather than laypeople.
Same thing for voting. Contemporary politics and governance are far too nuanced for the average citizen to discuss and understand. Important issues like reproductive rights, amnesty for international workers, re-establishment of non-human-impacted wilderness areas, and revenue enhancement for necessary social programs are easily distorted by political laypeople, and should be left to expert "voters" designated by politicians already familiar with governance.
Not exactly. The claim is that there was a single female who occurs in everyone's ancestral tree. It's a simple cladistic artifact.
/sarcasm
A bit off-topic, but do you believe we should allow civil servants to vote? How about people on welfare?
True, but he is also, as stated, a pompous ass, for which his "unusual intellect" is no excuse. I have spent my whole working life around people of "unusual intellect" and most of them are not pompous asses - only the ones who think they know it all.
100 years ago when scientists said we lived in a "steady-state" universe, the Bible said there was a point of creation. Science has now caught up to the Bible on this point.
a.k.a. Thou shalt have no other gods before me
What's your point. evolution != not believing in God
Would you consider "cross-cutting relationships" unscientific, then?
Nah. I work with a PhD in Chemical Engineering who's stupider than Darwin.
Well, I was trying to be sarcastic, I guess. The thinking of people like Gould and other Darwinian dogmatists is frankly anti-democratic, was my point.
What do you want to do, reinstate the old property qualification? I don't think it could be done. Plus isn't that a little unfair? If you have a problem with the way welfare moms vote, make 'em get off welfare and get a job---don't take away their vote. Same thing for civil servants----make more of 'em get a job in the "real world," but don't disenfranchise them.
And C++??
Glad you were smart enough (or maybe just indulgent enough) to see the humor in my post. :)
