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."
Natural selection and its popular counterpart "the survival of the fittest" are, however, at the core of the social-Darwinist gospel. I suspect the determinist ideas associated with social-Darwinism, including natural selection, will not be given up without a fight.
But little if anything in evolution theory has been proven and verified. The fact they have to keep modifying the theory proves that. Saying that they are modifying the theory in search of the truth doesn't overcome the fact that nothing's been proven in the first place. Nor does ridiculing those who take the Bible as fact.
Theories of physics or chemistry don't undergo these constant modifications. There have been lots of new theories in those disciplines over the years, but they don't contradict the ones that have already been accepted. Nor could they, since they had been proven by controlled experimentation. They simply add to them.
OK. Take two herds of horses. Keep one on the plains. Put the other one in an environment where the land rises one inch per centry. 1 foot in 1200 years, 1000 feet in 1.2 million years. Let's let it go on for say, 5 million years.
I'm sure the actual biologists here can do better, but I'd predict that the 'horses' on the higher, more mountainous area will resemble (at least in behavior, I don't know about appearence) present-day donkeys or burros more than the original horses. (eg, they'd be more sure-footed than their ancestors)
When you've invented time travel, let's conduct the experiment. Until then, we have to work with what's available, namely fossils and DNA.
Can some creationist/IDer give me pointers on how to set up an experiment where we can observe 'special creation'?
You read it, and you probably have a good idea of those who won't read it or who will try to diminish the assertions it contains. What do you think of the last line?
Indeed, it is possible that we will eventually see such information-processing capabilities as essential to life itself.
That is what you said.
The passage doesn't apply. It's not science. Has no place in an article about a scientist. The discussion was about Stephen J.Gould's knowledge in the field of evolutionary biology. You are labeling people because you don't agree with their views and trying to legitimize it by quoting from the scriptures. That is unfair.
Until then, I remain a skeptic and a heretic ( at least reading from the invective hurled by the dogmatic in the evolution camp ). And statements from people like that Fortey fellow continue to show that evolution is more of a religious creed to its proponents rather than something to be subjected to scientific inquiry.
I don't discount evolution, but I do have a problem with giving such a theory the status of a Natural Law.
Don't get me wrong -- creationism is pure bunk, and it betrays an uneasiness with religious faith if one has to contoct some scientific argument to support it.
No, seriously, I find the theory intriguing. I'm not surprised that such a discovery would be made in an age and society that is reforming its activities around information processing. Although I'm not a scientist, this theory of non-random genetic change through an information processing mechanism makes much more sense to me and fits much better with the evidence, which just doesn't support the theory of random genetic change and mutations occuring gradually over long periods of time.
As 'punk/eek' does to the theory of evolution by natural selection.
If the result was exactly as you predict, it would scarcely qualify as proof of evolution. Evolution is where species A turns into species B by the addition of some new characteristics or capabilities that were completely absent in A, such as a new organ or limb or wings or something. Increasing complexity. Everything is supposed to have evolved from a single cell organism. That's what transmutation of species is (Darwinian evolution). That's why mosquitoes becoming immune to a pesticide isn't evolution.
It always interests me what evolution supporters don't understand the theory of evolution. My minister recently said that people who think all life evolved from some muck being hit by lightning millions of years ago are overeducated for their intelligence. I have to agree.
and all without contradicting a single word that you've quoted.
Precisely. If you believe 'punk/eek', then you also believe everything that's been taught for decades on evolution is wrong. It's an admission that evolution hasn't been a proven fact all this time. Nor would punk/eek be either.
Nebullis is on record saying...
"wants(for the improvement of science--society) evolution taught intensively---starting in kindergarten"...a la joycelyn elders!
And fr-Patrick Henry..."total evolution--ONLY"...
devilcrat--nazis!
I'm not making this up!
Well, here is another citation.
The role of mutational and other biases in variation
In reality, mutation is not random in any sense other than in respect of being logically prior to selection (which is not a reason to call it "random"), and the idea of a bounteous Dobzhanskian "gene pool"-- the magic hat from which selection can pull any trick-- died years ago.
Although recent commentaries give the impression that the differences between classic neo-Darwinism and "evo-devo" are being resolved, we do not believe that this is the case. One cannot integrate these two contradictory views. Either propensities of variation exert an important shaping influence on evolution, or they do not. By implying the former, the "evo-devo" heterodoxy strikes at the root of the New Synthesis: its case for the supremacy of selection and its case against any possible internal causes of directionality. Far from being resolved, the controversy has not even been clearly recognized yet.
By RP...
I am offended that darwinists are so religious in their beliefs that they won't even allow a debate. One side will debate, one side won't. Hmmm.
Yeah...

Well, are horses and donkeys different species or not? Clearly (to me) not, because they can't produce fertile offspring. Assuming (for the sake of argument) they are descended from a common ancestor, just what 'new characteristics... that were completely absent..' are involved here? IOW, you're trying to set up a strawman - evolution is generally defined as the change in gene (allele) frequencies over time - it says nothing about brand new stuff being required.
such as a new organ or limb or wings or something
That sounds more like metamorphosis, which is a part of some theistic systems but has never been observed in the natural world.
darwinian slip...
