D-statistic tests for admixture in Dongsha Atoll Sinularia clade 4. Test numbers are listed on the right for each 4-taxon test (((p1, p2), p3), p4). Horizontal bars below the tips of the tree indicate which taxa were included in each test. S. humilis was set as the outgroup for all tests (indicated by gray bars). Tests are configured to ask whether P3 (black bars) shares more derived SNPs with lineage P1 (green bars) relative to P2 (orange bars). As illustrated to the left, Z scores are bar plots and D-statistics are histograms. Histograms are green for significant gene flow between P1 and P3 (BABA) and orange for significant gene flow between P2 and P3 (ABBA). D-statistics that were not significant are gray. Significance was assessed at an alpha level of 3.0 (i.e., when D deviates > 3.0 standard deviations from zero)
