Maximum-likelihood estimates and 90% HPDIs (between brackets) of parameter estimates under the IM model. (2N1m1 and 2N2m2 are the effective number of migrants per generation, respectively, into population 1 and 2. 1, population 1; 2, population 2; A, ancestral population.)

aSplitting time estimates (T = t μ) were converted into calendar years using a per-generation mutation rate (μ) of 5.0 × 10−4 and two generation times (G) 5 and 7 years.
