  1. Missing values are where the HPD of the parameters could not be reliably estimated by IMa2; m1 is migration rate into species 1 from species 2; m2 is migration rate into species 2 from species 1; t is the time since the species 1 and 2 split in years; Ne1, Ne2 and NeA are effective population sizes for species 1, species 2 and their ancestral population, respectively; 2N1M1 is population migration rate into species 1 from species 2 per generation; 2N2M2 is population migration rate into species 2 from species 1 per generation; aThe value corresponds to the first bin of the parameter space and hence could be interpreted as zero. *Asterisks indicates the estimates of migration rate that are significantly different from zero by the LLR tests [49, 63] at the P < 0.05 level and bold text indicates the significance after Bonferroni correction at the P < 0.0035 level (for the Hylobates comparisons) or at the P < 0.008 level (for the Nomascus comparisons).
