The time from the first population splitting event up to the second population splitting event was T = 220 generations.
The second population splitting event occurred in population 2. The population sizes after the second splitting event were N1 = 1815.1, N2 = 315.1, and N3 = 815.1.
He created a mathematical model that traced an ancestral Asian population splitting in two, with the splinter group venturing across the Bering Strait.
Interestingly, hierarchical structure among populations as introduced from recent admixture or population splitting appeared as limiting cases.
We used this value to directly convert the estimate t (the number of substitutions) to a number of years since population splitting.
The method estimates posterior probability distributions for both ancestral and actual population sizes, directional migration rates between the two populations, and the time elapsed since population splitting.
