Yet, you cannot demonstrate that there are multiple races, regardless of your position on "origins." There is no genetic justification for dividing the human race into racial groups. By definition, one race should not be able to breed with another case, and that is simply not the case with humans. There are no "groupings" of humans that are unable to breed with other "groupings." The Australian aborigines, for instance, were thought to be a "different" race, and yet that have been able to interbreed with European settlers. It is simply not true that there are multiple races of Homo Sapiens.

"By definition", you're wrong on that point.

I think you're confusing "race" with "species".
