Contextual information on the ancient samples used for the spatiotemporal analysis of the −13.910*T allele frequency (consisting of 1,434 individuals, of which 874 had enough coverage to call genotypes and thus were used to infer the frequency of LP).

The data are taken from David Reich Lab’s website [58], to which we added information for 3 additional newer publications [28,46,59]. The number in the “rs4988235” column corresponds to the number of reference allele at the −13.910 position (thus 0 means the alternative T allele, and 2 means the reference C allele). This is the information used in Fig 2 and S1 Fig. The last column (“LP status”) gives the phenotypic status of each individual based on its genotype at all reads (see Methods). This is the information used in S2 Fig.
