"However, neither Mallick et al. nor Malaspinas et al. exclude the possibility of multiple out-of-Africa dispersals." (from the commentary).<p>How is that one wave?
<i>We know there were multiple dispersals out of Africa, but we can trace our ancestry back to a single one.</i><p>How does that work? Everyone else died? What about recently discovered groups like the Red Deer Cave People? <a href="https://en.wikipedia.org/wiki/Red_Deer_Cave_people" rel="nofollow">https://en.wikipedia.org/wiki/Red_Deer_Cave_people</a><p>Doesn't evidence exist that groups interbreed, at least Denisovans / Neanderthals / Modern Humans?

I wonder how this would tie in to the human bottleneck theory. According to this theory[1], somewhere between 100,000 to 50,000 years ago, we had a human genetic bottleck event where there were only about 10 000 individuals left on the planet.<p>If true, we're one lucky species.<p>[1]<a href="https://en.wikipedia.org/wiki/Toba_catastrophe_theory" rel="nofollow">https://en.wikipedia.org/wiki/Toba_catastrophe_theory</a>
I can't read the full article. Even with all my cookies cleared it takes me to a subscription page. Same with web search. What's up with this?
Don't have the ref. onhand but read recently that African populace shows the greatest genetic diversity in <i>Homo sapiens sapiens</i>.<p>India comes in at second place, presumably because of larger migration to the subcontinent compared to Europe.
I often wonder how people reconcile such scientific reports with what religious texts say.<p>Some weeks ago, while discussing with a colleague about the human tendency for discrimination on any grounds, I'd said "After all, we humans were once apes in Africa". He responded with "Hey, I'm a follower of so-and-so religion, and our religious text says that God made everything within a week. So, please let's not discuss topics that are hurtful to me".
And Australian Bushmen, Polynesians, south Indians show us the multiple waves of migration, but who are they compared to a fancy statistical model made from poorly understood DNA sequences by clever hipsters!
