ABC results of the SSV model for each population.

Bayes factor (measure of confidence) and the resulting posterior probability (Post. Prob.) for the SSV model in each population, ordered by latitude. t0: time when selection starts; SNA: selection strength in non-African population; fsel: frequency of allele at selection start. The median of the posterior distribution of each inferred parameter is shown together with its 95% confidence interval (2.5%–97.5%).
