Phylogeny and explored migration bands for G-PhoCS analysis. We used the indicated phylogeny for eastern lowland (E), western lowland (W), Cross River (R) gorilla species and human (H), and tested the indicated migration scenarios. Scenario 1: No migration. Scenario 2: Bidirectional migration between western and Cross River gorilla. Scenario 3: Bidirectional migration between Cross River and eastern gorilla. Scenario 4: Bidirectional migration between western and eastern gorilla. Scenario 5: Migration from western to eastern gorilla and from Cross River to eastern gorilla.
