> I'm still confining myself to innovation, and for me testing against geochemical changes means adaptation. You move onto epigenetics again before returning to what I see as the crucial question: How do we suddenly have entirely new species? "Darwin's guess is not supported in the fossil record as Gould has shown.-There is a marvelous old video starring Eldridge and Gould on puntuated equilibrium with an explanation of their version of the theory: stasis and then a burst of new branching, bush style over 50-100 thousand years, on blog Sandwalk, today.-http://sandwalk.blogspot.com/
