Stages in female human evolution

Human evolution. Artwork of female apes and humans showing some of the stages in human evolution. At left, Proconsul sp. (23-17 million years ago) is depicted hypothetically as an African ape with both primitive and advanced features. To its right is Australopithecus afarensis (>4-2.5 Myr BP), which walked upright on two legs. Homo habilis (2- 1.6 Myr BP) was truly human ("Homo"), resembling A. afarensis but also using stone tools. About 1.8 Myr BP, H. erectus appeared in Africa, using fire and wooden tools. H. erectus is thought to have migrated from Africa into Eurasia. H. neanderthalensis (150, 000 years BP) was closely related to modern humans, H. sapiens (right)
