That might be jumping the gun a little. I don't know how inter-species breeding viability is confirmed, but I think that proving this may require actually growing sex cells. There are certainly others on the forum with much better knowledge of this than me who could confirm this though.
I would have to go hunting, but there has been a skeleton discovered with both modern man and nea (can't spell ) characteristics. The modern man was the dominant gene and won through in the end leaving no traces of nea man today. (bar some rugby players)
