Want to see Freeman Dyson and Richard Dawkins butt heads? It begins with a talk Dyson gave to an Edge conference in which Dyson (watch the whole talk) made these comments:
“By Darwinian evolution he [Woese] means evolution as Darwin understood it, based on the competition for survival of noninterbreeding species.”
“With rare exceptions, Darwinian evolution requires established species to become extinct so that new species can replace them.”
Dawkins rightly objects. Those are weird claims: the first is, I think, a misreading of Darwin. Darwin says something very different.
