Quote:
Race isn't truly biological, anyway; it's more of a cultural thing. Like, here in the US, a person can be labeled "black" even though their features are closer to Caucasian, because they have a small detectable amount of African heritage, even though most of their ancestors came from Europe. And they can be culturally black, too, just lighter-skinned than most.
I know ethnic labels are cultural rather than biological, but that doesn't mean there aren't biological aspects to race. 23andme could tell from my genes that my ancestors came from Northern Europe without even seeing me. (They tell a lot of American Blacks they're mixed-race. Which a lot of Africans can tell by looking at them.)
