Austral means southern and pithicus means ape. Thought to have roamed the african planes for about 5 million years. About 1. 3 m tall and had small brains. The first homo species likely evolved from one species of. Coexisted with the australopithecus for about million years until the australopithecus died out. 200,000 years ago, early homo species gradually replaced in the. About 50,000 years ago, modern humans migrated outside of. Kingdom, phylum, class, order, family, genus, species. Animal, chordate, mammal, primate, hominid, homo, sapien.
