  • Supporting Materials Results Demographic
    Supporting Materials Results Demographic model selection: using PSMC/MSMC We applied the pairwise sequentially Markovian coalescent (PSMC, Li and Durbin 2011) and multiple sequentially Markovian coalescent (MSMC, Schiffels and Durbin 2014) as independent means to explore the demographic history of our populations (Materials and Methods). PSMC infers effective population size over time from a single diploid genome, while MSMC measures genetic separation of populations using relative cross coalescence rates between pairs of haplotypes from two populations. We applied both PSMC and MSMC to our quality-controlled intergenic data. The PSMC curves of the farmers begin to separate from those of the Pygmies roughly 100–200 kya (Figure S3A), suggesting that the ancestors of the farmers and Pygmies began differentiating from each other as early as 100–200 kya, consistent with the inferred divergence time in Model-1. The MSMC curves indicate declining genetic exchange between Pygmies and farmers ~40-60 kya, suggesting that these two populations may have diverged from each other at this time (Figure S3D-E). To test if Model-1 and Model-2 recapitulate the divergence times between farmers and Pygmies indicated by PSMC/MSMC, we applied both methods to simulated genomes under both models (Figure S3B-E). Under Model-1, the PSMC curves of the simulated Pygmy and farmer genomes split at about the same time as in the PSMC analysis of the real data (Figure S3B), while the two simulated populations of Model-2 do not show clear separation until ~70 kya (Figure S3C). The MSMC curves of Model-1 and those of real data agree well, but Model-2 seems to fit the MSMC curve from the real data poorly (Figure S3D-E).
