We can only guess...
I think when DNA evidence smacks down any group’s bigoted claim of racial purity (whatever that means), be it neo-Nazis, Aztlan lunatics, African supremacists, etc, it is a good thing. If people have been intermixing for tens of thousands of years, it really renders racial prejudice idiotic and moot.
God created the soul/spirit of all His children. Up until the OJ trial I had no clue what DNA could describe about any one flesh body. God sure never claimed any of His children had supremacy over another because of skin color, that is the devil's workshop. God's requirement is love from His children regardless of their ethnicity.
