FIGURE 3 | (A) Maximum Likelihood (ML)-tree inferred by TreeMix allowing eight migration events. Letters A–H refer to migration edges as defined in Table 1. Migration H, not confirmed by the f4 statistic after the Holm-Bonferroni correction (see Table 3), is shown using a two-dashed line. Migration arrows are colored according to their weight and colors are explained in the palette on the left. The scale bar shows ten times the average standard error (s.e.) of the entries in the sample covariance matrix. Drift parameter is shown on the x-axis.
