Re: Other than human, non of our genes can be said to be of any pure race
Significant fractions of modern humans' genome has been contributed through cross-breeding with Neanderthals and Denisovans. Both are different species from ours.
I hate to break it to you, but part of the definition of species is that two members of the same species can generate viable, fertile offspring.
By that measure, the two groups mentioned (and they must have had viable, fertile offpring for the genome to mix with H. Sapiens) can't be a separate species..
Separate sub-species sharing significant ancestry with H. Sapiens - yes. But not an entirely separate species.
