Well, the DNA breeds true, but that makes no remark on the fallacy of human races. It simply says that THE human race is not a goal, or an end.
The changes I see happening have nothing to with human divisions, but I see differing tendencies in the ability to trace huge volumes of logic in those raised under the sign of the CRT.
I would submit anyone who argues that mankind are different species is failing to "get" the model. But that is not the same as saying "no evolution"...a lot of evolution occurs, I suppose, before you can draw a species line. With no implication of superiority; survival is relative to the conditions in which it occurs.
