Figure 2. Genetic characteristics of the Oceanian ancestry cline.

Figure 2

a, Estimated proportion of First Remote Oceanian ancestry. b, Difference between First Remote Oceanian ancestry estimates on chromosome X and the autosomes. c, Denisovan ancestry estimates are inversely related to First Remote Oceanian ancestry estimates. d, Estimated date of admixture in all populations with at least 4 individuals and significant evidence of decay of weighted admixture linkage disequilibrium as measured in ALDER. We used Han and New Guinean Highlanders as surrogates for the ancestral populations. We assumed a generation interval of 28.1 years, and show 95% confidence intervals (thin whiskers) incorporating uncertainty both in the ALDER date and the value of the human generation interval. We show the range of radiocarbon dates for the ancient individuals. e, Conditional heterozygosity (genetic diversity) estimated by drawing two random chromosomes from different individuals at each locus, using only SNPs ascertained in a single Yoruba, and restricting to transversion SNPs to avoid any concerns about inflated heterozygosity due to ancient DNA degradation. Thick and thin error bars in all five panels correspond to 1, and 1.96 standard error of the estimate.
