Gould's theory is "punctuated equilibrium", which states that darwinian accumulation of small changes is/was invalid.

I've read most of Gould's books and most of the Nature articles from which they are taken. I've never seen anything like that. Do you have a source that isn't a cobbled together quote taken out of context?

More to the point, I believe your statement about is utterly incorrect. Please don't post any out of context quotes from creationist sites. ALS tried to do that and I found the complete quote and the context, proving that the website lied about the source, content and meaning of the "quote".

The reason I can be sure you are wrong about Gould is that I have read him. He was a great admirer and defender of Darwin. Gould simply has a hypothesis that states that small genetic differences can have huge effects in the final form of a creature, giving the outward appearance of varying rates of change.

The rate of environmental change can also result in different rates of selection. The only thing Gould says taht differs from Darwin is that we now have more and better information about specific histories.

What Gould really said:

"I count myself among the evolutionists who argue for a jerky, or episodic, rather than a smoothly gradual, pace of change. In 1972 my colleague Niles Eldredge and I developed the theory of punctuated equilibrium. We argued that two outstanding facts of the fossil record—geologically "sudden" origin of new species and failure to change thereafter (stasis)—reflect the predictions of evolutionary theory, not the imperfections of the fossil record. In most theories, small isolated populations are the source of new species, and the process of speciation takes thousands or tens of thousands of years. This amount of time, so long when measured against our lives, is a geological microsecond. It represents much less than 1 per cent of the average life-span for a fossil invertebrate species—more than ten million years. Large, widespread, and well established species, on the other hand, are not expected to change very much. We believe that the inertia of large populations explains the stasis of most fossil species over millions of years.

"We proposed the theory of punctuated equilibrium largely to provide a different explanation for pervasive trends in the fossil record. Trends, we argued, cannot be attributed to gradual transformation within lineages, but must arise from the different success of certain kinds of species. A trend, we argued, is more like climbing a flight of stairs (punctuated and stasis) than rolling up an inclined plane.

"Since we proposed punctuated equilibria to explain trends, it is infuriating to be quoted again and again by creationists—whether through design or stupidity, I do not know—as admitting that the fossil record includes no transitional forms. Transitional forms are generally lacking at the species level, but they are abundant between larger groups. Yet a pamphlet entitled 'Harvard Scientists Agree Evolution Is a Hoax' states: 'The facts of punctuated equilibrium which Gould and Eldredge…are forcing Darwinists to swallow fit the picture that Bryan insisted on, and which God has revealed to us in the Bible.'"
