Without reading his research, the article seems to be describing puncuated equilibrium. The article does make a good point though; that as scientists, biologists and anthropologists should explore alternative models of evolution. I stand pretty firmly in the school of puncuated equilibrium, but thats not to say that my ideas about are necassarily correct, just that what I learned about it seems more logical in the context described by Gould than does gradualism. If another theory comes along with a little more science to back it up, we should all be open to evaluating it.
