Individual markers form clades (e.g. mtDNA phylogeny) but in humans you'd have a huge snaggle across many markers. But otherwise interesting stuff.

But that's normal: Bushmen (Khoisan in general) diverged first (clade mtDNA L0), then Pygmies and some elements in West Africans (clade mtDNA L1) and you still have Yorubas and most other Africans together with Eurasians-plus. Even some admixture can't mask the depth of these fundamental divisions prior to the OoA. “… this strange result that populations like the Yoruba might be in a clade with non-Africans against Khoe and Bushmen”.
