If you look into K and R survival strategies if tells you part of what is going on. Blacks are more R and whites are more K. Asians are the most K

Noting, for the record, that the author of the cited book Erectus Walks Among Us, Richard D. Fuerle:

• Believes blacks are a different species ("homo africanus") than whites (homo sapiens);
• Considers sex between whites and blacks to be bestiality;
• Holds no relevant educational degrees related to anything he writes about on race; and
• Argues in favor of eugenics and segregation.

I think I'll pass on Mr. Fuerle.

Richard D. Fuerle....I have never read his books. You will find others writing about R and K strategies all across biology. Others that will have credentials acceptable to you
