Extended Data Figure 7: Schematic of second alternative admixture graph.

Results are shown with a single-component deep source for West Africans. Branch lengths are not drawn to scale. Points at which multiple lineages are shown diverging simultaneously indicate splits occurring in short succession (whose order we cannot confidently assess) but are not meant to represent exact multifurcations. HG, hunter-gatherer; AP, agro-pastoralist.*Proportion not well constrained (for Mbuti, the sum of the two indicated proportions is well constrained but not the separate values). See Supplementary Information section 3 for full inferred model parameters.
