Lack of Human varieties. Genetic "cleansing" through history?

You are mixing apples and oranges. Varieties of house cats are, indeed, varieties of the same species. But when you go to tigers, lions, pumas, cheetas, jaguars, you are talking about diverse species. For the human case you might as well be talking about chimpanzees, gorillas, bonobos, orangutans.You need to clarify whether you are wanting to discuss varieties within the human species, or closely related species.
