Again, (giving you one more chance to be evasive), what is your definition of "species"?
Missed this earlier and I think it deserves a response. I would object because blacks and whites can interbreed with no problems. There's not enough genetic difference for them to be considered different species. Other than external characteristics (color mostly) I don't know of anything else that is different. Same blood types etc. There is only the human species, not the white species or black species.
