[QUOTE]Originally posted by phenelzine: [QB] Added to above: I said the intermediary position of Horners' was due to the pre OOA evolution in Africa of Cluster Y. Later there was admixture between them and elements of Cluster X. The Fst distance (co-efficent of co-ancestry or biological kinship) between Horner's and the Yoruba is not magical, it's biological, and involves deep population structure in Pre-OOA Africa. From Tishkoff's latest: "When two clusters are assumed in the STRUCTURE analysis (K = 2), individuals can primarily be assigned to African (orange) or non-African (blue) clusters, consistent with the PCA (Fig. 3). Individuals from Saharan and Eastern Africa show heterogeneous ancestry, reflecting descent from populations ancestral to non-Africans and/or gene flow from non-Africans into Africa." "African and non-African Associated Ancestral Clusters based on the populations showing the highest levels of ancestry for each inferred ancestral cluster) are highly divergent." "The Africa-wide STRUCTURE result (Fig. S13) largely recapitulates the African PCA results. Specifically, the western and eastern African populations were distinguishable at K=2..." [/QB][/QUOTE]
