> We already know by now, that before going out of Africa at least two major genetic branches developed in addition to early Eurasians.

Nice of you to acknowledge genetics.

> At K=4 and clustering by genetic distance, they would likely represent two clusters while the rest of Africa would fall into one of remaining two.

I suppose they would.

> Not even close to what average American would understand.

The average American would understand if those two branches lived among us today. The value of science is to inform us of what is occurring now and to predict what will occur next, including the impact of immigration on test scores.

Shall I break the news or you find out yourself?.. ok, I will do it.

Those two branches do live among Americans. Afro-American people have the biggest genetic diversity in America and their genetic subgroups are so distinctive that they require separate testing in clinical studies. I bet you won’t be able to tell the difference between them from their appearance though. Now good luck redefining the concept of race with this knowledge.

If you were not referring to extinct branches I don't know why you thought "they would likely represent two clusters" if they did not already in the clustering given.

Yes, and?

Maybe, and?

Good luck trying to deny biological race when you've just listed more evidence for it.

Read the study with the clustering. I did it, so you should too.

This is my last reply to you. If you need more answers, there’s already more than enough facts for you here to verify and learn something new in the process.
