The literal evidence of what any DNA demonstrates makes void a whole lot of claims. Wonder what the Adam's DNA would show?
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.
