Well obviously it's dispersion.

Are you serious ?
It's not even like ooa would stop anyone from being racist.

>humans aren't as easily categorized into subspecies as most other animals due to the fact that we're nowhere near as geographically constrained. Take the crow example from >>15670540 (You) and note how narrow the hybrid band is
The crow exemple is of populations that are considered different species (for that reason among others), not subspecies.
Subspecies usually are clinal when they are in contact. Like wolves in >>15670546, their genetic structure doesn't actually neatly follow borders.


>Or all three should be different subspecies? This implies that either a 0.12 or 0.09 difference is sufficient to be considered a separate subspecies. How far do you want to go? 0.06? 0.03? 0.01?
That is another question, which has never been a big issue for other clinal substecies group. To take the old comparison, you have no problem using the red and orange categories even though you'd be unable to tell me exactly at what frequency one ends and the other begins.
Same for subspecies, it doesn't matter much if the line is drawn more or less arbitrarily, like it was for wolves or others.

That being said we do have material basis to draw the lines over geographic divides, like the sahara, and as >>15672853 says we know the history of human population migrations and splits that separated groups over geographic areas, and that also can inform the line drawing.

>>You are "subspecies" of Africans in any case,
Oh I see, you're saying that an "african" subspecies is necessarily paraphyletic if it doesn't includes the rest of humanity.
But that's an easily solved issue : no one said such a subspecies has to exist. It's fine if for example, khoisan peoples are separated from other current africans into their own subspecies.

>Not sure how you square that circle given how ridiculously inbred humans are.
We're not very inbred. There is significant genetic distance between human groups that cause significant issues in multiracial societies.

Well it is reasonable.
