Ernst Mayr

According to the concept of transformational evolution, first clearly articulated by Lamarck, evolution consists of the gradual transformation of organisms from one condition of existence to another. ↗

All I claimed was that when a drastic change occurs, it occurs in a relatively small and isolated population. ↗

Evolution thus is merely contingent on certain processes articulated by Darwin: variation and selection. ↗

I did not claim that speciation occurs only in founder populations. ↗

Indeed, I was unable to find any evidence whatsoever of the occurrence of a drastic evolutionary acceleration and genetic reconstruction in widespread, populous species. ↗

It seems to me that for Darwin the pulsing of evolutionary rates was a strictly vertical phenomenon. ↗

Life is simply the reification of the process of living. ↗

Living in an entirely different physical as well as biotic environment, such a population would have unique opportunities to enter new niches and to select novel adaptive pathways. ↗

New gene pools are generated in every generation, and evolution takes place because the successful individuals produced by these gene pools give rise to the next generation. ↗

The major novelty of my theory was its claim that the most rapid evolutionary change does not occur in widespread, populous species, as claimed by Most geneticists, but in small founder populations. ↗
