a, Map of location of samples highlighting the diversity/selection sets. b, Sample-level heterozygosity is plotted against distance from Addis Ababa. The trend line represents only non-African samples. The inset shows the waypoints used to arrive at the distance in kilometres for each sample. c, ADMIXTURE plot (K = 8 and 14) which relates general visual inspection of genetic structure to studied populations and their region of origin. d, Box plots were used to visualize the Denisova (red), Altai (green) and Croatian Neanderthal (blue) D distribution for each regional group of samples. Oceanian Altai D values show a remarkable similarity with the Denisova D values for the same region, in contrast with the other groups of samples where the Altai box plots tend to be more similar to the Croatian Neanderthal ones. Boxes show median, first and third quartiles, with 1.5× interquartile range whiskers and black dots as outliers.
