I thought this was already established?
True, I know of two separate DNA studies as early as 1996 that established this fact. Also to my surprise, anthropologists generally reject Cro Magnon as precedent species to homo sapian sapain (man). Research on this dates back as early as 1978. So that are two "links" missing right before man on the evolutionary chain. But no need to throw out evolution since there is much consensus on the issue.
