Humans are the only extant members of the subtribe Hominina. Together with chimpanzees, gorillas, and orangutans, they are part of the family Hominidae. Humans are terrestrial animals, characterized by their erect posture and bipedal locomotion; high manual dexterity and heavy tool use compared to other animals; open-ended and complex language use compared to other animal communications; larger, more complex brains than other animals; and highly advanced and organized societies. Early hominins—particularly the australopithecines, whose brains and anatomy are in many ways more similar to ancestral non-human apes—are less often referred to as "human" than hominins of the genus Homo. Several of these hominins used fire, occupied much of Eurasia, and the lineage that later that gave rise to Homo sapiens is thought to have diverged in Africa from other known hominins around 500,000 years ago, with the earliest fossil evidence of Homo sapiens appearing around 300,000 years ago.
