Among horses and dogs, mixed breeds are usually the most virile, evolved and sharp. The same logic exists for human beings as well. According to modern-day scientific wisdom, the concept of "race" is incorrect because human beings have always been mixing since the beginnings of time. Slavic Russians/East Europeans/Finns have Oriental Chinese mixture. White Afrikaans of South Africa have some African genetic ancestry. And here in this report, one-third of White Americans have recent African ancestry between 2-20% African roots
