You're the one who doesn't even know what 50% African and 100% African means.
Correct. It's meaningless gibberish unless we can first agree on some meaning for it. Whatever meaning we use will have to be something we posit and agree on among ourselves, rather than discover in nature (i.e. it must be socially constructed). Because Africa is a place, and not something in DNA.
So anything that's not 100% certainty is as good as 0% certainty?
Not at all. And again, this is just illogical and has nothing to do with anything I said.
It's not ridiculous, because you can take genome samples of people representative of African countries and pool them, then compare them to people living in Japan, India, Australia, the Amazonian rainforests, this is where you'll find patterns of differences.
I don't deny that. But it does not follow from that that you could ever devise a genetic test to show that none of a person's ancestors were born in Africa. Your test could show that I have 0% African ancestry even if both of my parents were born there.
If you actually read the literature associated with the links you've provided me (which themselves say practically nothing relevant to this discussion), you will find that the very scientists practicing those tests themselves agree with everything I've said here.
