alt Hacker NewsThat just means you can't call Africans one "race" because they hold all the genetic diversity on the planet. But it doesn't mean there's not some meaningful genetic grouping of populations that splintered out of Africa. Or, concretely, I'm struggling to square what you're saying with the fact that I tell my doctor I'm Hispanic because that means a higher genetic predisposition to things like diabetes.
Hispanic is probably the perfect example for this. A blonde Argentinian is probably not predisposed to diabetes. What I’m trying to say is racial categorizations don’t follow any rules based in our biology or genetics. For it to be scientific you would need to be able to categorize any given individual 100% based on some unchanging rule that is based on underlying biology. We cannot currently do that and what I’m saying is I don’t think you can come up with a rule like that without the result being hundreds of thousands of different categories of “races”.
