Modern human genetic variation projected on axes of variation defined by chimpanzee, Denisova, and Neandertal. (A) A model of hominin evolutionary history suggested in the work in ref. 24 with putative admixture events indicated by arrows. (B) Population means for each of 62 populations. (C) PC1 in individuals from Eurasia and America as a function of distance from East Africa (kilometers). (D) Interpolated spatial distribution of PC2 [transformed for visualization as (−1) × log10 (x + C), where x is the PC loading and C = 0.04231] in individuals from Eurasia, Oceania, and America. (E) Interpolated spatial distribution of the frequency of Denisova alleles at SNPs where Denisova is different from chimpanzee and Neandertal. Sample localities are indicated with rectangles.
