Essentially, Davison tries to revive a form of Goldschmidt’s “hopeful monster” theory, suggesting that large chromosome-level mutations, “semi-meiosis” and/or asexual reproduction can and usually did produce instant species and even instant general and families. He even quotes the old line about a bird hatching from a reptile egg, as if this kind of thing was feasible and routine in evolution. But this doesn’t make any genetic or common sense, since again, he has no mechanism to direct or coordinate all the genes required to do this, or to preserve and spread any such monsters, on the highly unlikely chance they’d be viable and adaptive. Without natural selection, at times he seems to hint that the missing agency might be some divinely creative act or process, but fails to clarify this.
