No tails Broad Interorbital region of face Broad and long anterior palate (upper lip area)

Proconsul –Found in Africa, Europe, and Asia

Late Divergence Hypothesis –Common ancestor to contemporary apes Which Miocene ape? Around 15 mya –Human Chimp split Around 6 mya Blood protein evidence DNA evidence –Now/soon genetic sequencing (just did chimps) –DNA Hybridization
