ADMIXTURE analysis of 92 African and 62 West Eurasian individuals. Each bar is an individual and colors represent the proportion of inferred ancestry from K ancestral populations. The bottom bar shows the language classification of each individual. K = 2 separates the African and West Eurasian populations. African hunter-gatherer populations Khomani San, Ju|’hoan, Sandawe, Hadza, and CRHG populations are distinguished from the rest of the populations at K = 3 (yellow bar). From K = 5, CRHG populations emerge as a single cluster. With the increasing of K, the populations are largely grouped by their current language usage
