I should have said the truth of the lie of his punctuated equilibrium. Gould looked at the fossil record, realized that the evidence contradicted classical evolutionary theory, but instead of questioning the theory, he simply came up with a twist on the theory which explained the seeming gaps in the fossil record. Can anyone prove that punctuated equilibrium isn't a total fabrication? Gould, like all evolutionists, hold to evolution as gospel, and promote it with evangelistic fervor, which is why I say that evolution isn't science (it can't be observed or replicated in the laboratory), but is ideology. It's their religion. To believe in evolution requires certain leaps of faith.
Gould's theory of punctuated equilibrium is an elaboration, refinement on Darwin's theory. I like how Michael Shermer put it "[Punctuated Equilibrium] no more proves Darwin wrong than Einsteinian relativity proves Newton wrong."
