Overview of populations investigated in this study.

(A) Partial map of Africa and Europe showing the populations investigated in this study. Gumuz and S.Sudanese were not included in the figure as the geographic sampling coordinates were unclear. Coordinates were approximated for the 1000Genome, HGDP, Egyptian, Nzime and Somali populations. This study includes eleven populations from the 1000Genome Project that have been sampled from areas outside of the map range, indicated by the arrows. Colors of the symbols indicate project affiliations. A zoom on Sudan and South Sudan shows the geographic midpoint of the populations sampled in this study. The colors of the symbols indicate linguistic affiliation, Nilo-Saharan speakers are shown in red and Afro-Asiatic speakers in blue. The Nuba, shown in red, also speak Kordofanian, a Niger-Congo language. (B) Pairwise FST of the Sudanese and South Sudanese populations. The key shows the FST-values on the x-axis and the y-axis displays the amount of observed instances in a histogram. A UPGMA tree is shown that was calculated using the FST distance matrix.
