Note.—Population history estimates by using G-PhoCS when assuming a range of human–gorilla divergence time (8, 10, and 12 Ma). We assumed migration events from western lowland to eastern lowland gorilla and from Cross River to eastern lowland gorilla (fig. 1, scenario 5). Values in parentheses correspond to 95% credible intervals.
