Extended Data Fig. 5 | Schematic of f irst alternative admixture graph.
Results are shown including ancient individuals from Taforalt in Morocco
associated with the Iberomaurusian culture, with the Shum Laka individuals
modelled as having a mixture of ancestry related to western Central African
hunter-gatherers plus two additional components: one from within the main
portion of the West African clade, and one that splits at nearly the same point as
one of the sources that contributes ancestry to the Taforalt individuals. Branch
lengths are not drawn to scale. Points at which multiple lineages are shown
diverging simultaneously indicate splits that occur in short succession (the
order of which we cannot confidently assess) but are not meant to represent
exact multifurcations. *Proportion not well-constrained (for Mbuti, the sum of
the two indicated proportions is well-constrained but not the separate values).
Supplementary Information section 3 provides the full parameters of the
inferred model.
