Clustering of KhoeSan populations and fine-scale population structure between the Nama and ≠Khomani San. A PCA of the Affymetrix Human Origins data set depicts the clustering of unrelated individuals based on the variation seen in the data set. Colors mimic similar major ancestry colors as shown in Figure 2. Yellow denotes populations with majority northwestern Namibian ancestry; purple denotes populations with majority Bantu-speaking ancestry; pink indicates southern Kalahari majority ancestry, green indicates northern Kalahari majority ancestry, and blue indicates circum-Kalahari ancestry. The red and green circles denote the fine-scale separation of the Nama and ≠Khomani populations (specified by triangles and squares, respectively). Note that these colored ancestries and the PCs do not map onto subsistence neatly (Figure S5).
