![]() Begun concluded that early primates flourished in Eurasia and that a lineage leading to the African apes and humans, including to Dryopithecus, migrated south from Europe or Western Asia into Africa. Notharctus tenebrosus, American Museum of Natural History, New Yorkĭavid R. Other similar basal primates were widespread in Eurasia and Africa during the tropical conditions of the Paleocene and Eocene. One of the oldest known primate-like mammal species, the Plesiadapis, came from North America another, Archicebus, came from China. The evolutionary history of primates can be traced back 65 million years. The Homo genus is evidenced by the appearance of H. habilis over 2 mya, while anatomically modern humans emerged in Africa approximately 300,000 years ago. Hominins (including the Australopithecine and Panina subtribes) parted from the Gorillini tribe ( gorillas) between 8–9 mya Australopithecine (including the extinct biped ancestors of humans) separated from the Pan genus (containing chimpanzees and bonobos) 4–7 mya. African and Asian hominids (including orangutans) diverged about 14 mya. Primates produced successive clades leading to the ape superfamily, which gave rise to the hominid and the gibbon families these diverged some 15–20 mya. Primates diverged from other mammals about 85 million years ago ( mya), in the Late Cretaceous period, with their earliest fossils appearing over 55 mya, during the Paleocene. The study of human evolution involves several scientific disciplines, including physical and evolutionary anthropology, paleontology, and genetics. This process involved the gradual development of traits such as human bipedalism, dexterity and complex language, as well as interbreeding with other hominins (a tribe of the African hominid subfamily), indicating that human evolution was not linear but weblike. Human evolution is the evolutionary process within the history of primates that led to the emergence of Homo sapiens as a distinct species of the hominid family, which includes all the great apes. The hominoids are descendants of a common ancestor. Evolutionary process leading to anatomically modern humans
