Two Main Hominid Groups Genus: Australopithecus Genus: Homo example: A. afarensis (“Lucy”) example: H. habilis More recent (2 MYA – present) More human-like Much larger brain Completely bipedal Found in Africa, Asia, and Europe) Earlier (4 – 1.5 MYA) More ape-like Brain size: similar to the size of chimpanzees First bipedal primates Found in Africa
