The Colobinae, or leaf monkeys, are distributed geographically across Africa and Asia. Colobinae are specialized arborealists and leaf eaters with sacculated stomachs, sheering teeth, reduced thumbs, and very mobile shoulders. Colobinae diverged ~10.9 million year ago (Ma) from the Cercopithecidae in Africa, and Asian colobines appear in the fossil record in the late Miocene ~8.5 Ma. However, an incomplete fossil record means little is known about the evolutionary pressures that led to Asian colobine migration and diversification. Here, we use recent fossil discoveries and geospatial information to develop hypotheses about how geographic barriers played direct roles in Asian colobine evolution. …
