• Our ancestors were chimpanzees or any other modern ape. Chimpanzees and humans represent two divergent branches of the hominoid tree that evolved from a common ancestor. • Human evolution is a direct series of steps leading directly from an ancestral hominoid to Homo sapiens. Some groups have dead ends. Some groups coexisted. • Various human characteristics (upright posture and enlarged brain), evolved in at the same time. Different features evolved at different rates (bipedalism or upright posture was first).
