Crucial is the proof that since the Neolithicum evolutionary change increased rather than decreased, and that regionally and indvidually different. Overall, especially since the medieval times, Europe's biological niveau decreased while the numbers increased, which can be attributed to contraselective, dysgenic trends.
Without selection no population keeps a niveau but get broader and broader variation with more minus- or at least less positive variants and genetically inherited traits. This is very important from the Eugenic perspective as well as if looking at racial developments, since in the past, especially egalitarians often argued that the limited time doesnt allow significant genetic and racial changes in human populations, so that all humans are basically equal with just minor changes since the split or that in Europe racial changes couldnt take place in the respective time frame - which is wrong either.
Today we evolve in a negative direction, which leads us to the Eugenic-debate:
The Coevolution of Parochial Altruism and War - Aspects of Group Selection
Future evolution of human appearance
My argumentation in favour of an Eugenic policy
The racially progressive tendencies in sapiens:
Racially progressive tendencies in Homo sapiens
This also negates "the must" of long racial continuities, and speaks for faster racial changes. Of course this news are not that new at all, but its one piece after another making up the whole pictures of faster human evolution (for bigger mammals - relative).
