Fig. 4: Diagrams showing the eight demographic scenarios which were tested in fastsimcoal. SC1–SC6 were designed to test the likelihood of the exchange of genes between the different populations.

The following two scenarios then tested for the presence of population growth in the SVA and EUR populations. Exponential population growth following the EUR-SVA divergence was implemented in SC7, while SC8 accounted for population expansion, which predates the aforementioned split.
