Electronic supplementary material Genetic data and analyses To compare the genetic differentiation of Bantu-speaking populations with that observed in other African linguistic phyla we included data from as many African populations as possible. We considered only those populations from previous studies that have a sample size of at least 10 chromosomes. With respect to mtDNA, a total of 5,018 sequences of the first hypervariable segment, consisting of positions 16024-16383, excluding the polycytosine stretch at positions 16183-16193, and with less than two uncertain nucleotide callings, were included in the anal- yses. For the Y chromosome, we used the data from 2,445 individuals genotyped for 11 STRs and various SNPs reported in [1]. For the autosomes, data from 2,503 individuals genotyped for 848 STRs [2] were used for the analyses. We first removed 136 STRs with more than 40% missing values over all individuals and subsequently looked for overlap of the remaining 712 STRs with those reported in [3], ending up with a total of 560 STRs.
