list different human races as different species? There are many physical differences between Blacks, Whites, Hispanics, Asians and so on including bone structure, skin color, hair, skin secretions, susceptibility to disease (sickle cell anemia for example). When can you draw the line and stop worrying about peoples' feelings in order to be scientifically correct? Genus, and Family should stay but I think the species should change in my opinion.
If you're going to be racist please don't post (even though i know you will).
