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; N_e1, N_e2 and N_eA 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).
