"...the evidence that macroevolution has happened is all around us, in the patterns of biogeographical distribution of species and in the fossil record. What is not so obvious is the mechanism(s) by which such macroevolution has occurred. Prof. Giertych is probably right in asserting that the "modern synthesis" mechanisms grounded in theoretical population genetics are insufficient to explain macroevolution. However, scientists within the field of evolutionary biology have been saying the same thing for over a century." Allen MacNeill, Cornell University evolutionary biologist.
Well, they may have been saying this for over a century, but, if so, they haven't been very public about it.
At any rate, MacNeill isn't saying that evolution never happened. He believes quite the opposite. What he's saying is that the traditional Neo-Darwinian view that evolution is the product of a synthesis of natural selection and genetic mutation is an inadequate explanation. Large scale evolution (macroevolution) simply cannot be explained in terms of any purely mechanistic processes of which we are aware.
MacNeill is not known to be overly sympathetic to Intelligent Design, but what he's claiming is what ID theorists have been asserting for two decades to considerable resistance from the Darwinian establishment which, according to MacNeill, has largely been in agreement with them. That's pretty strange.
