Virtually all evolutionists would now agree that the various people groups did not have separate origins. Meaning the different people groups did not all each evolve from a different group of animals. Of course, they believe groups like the Aborigines and Chinese have had many tens of thousands of years of separation. Most people believe that there are such vast differences between groups that there had to be many years for these to somehow develop. We now know that they can develop very quickly in groups isolated from others.
