I think you are behind the times on this one, blam. Go to any world-class conference on this subject and see most of the pioneering anthros distancing themselves from the old Darwinian theories and old texts and moving the dividing line up to ~10,000 years ago and closer. Some are still holding at the close of the last ice age, ~13,000 years at most.
For a new species of human? Point me in the direction of just one. You know me. Shoot, I'll check it out.
