Human

"With World War III around the corner, we humans fear of possible extinction."

--Su Ji-Hoon, The Arrival

Modern humans (Homo sapiens, ssp. Homo sapiens sapiens) are the only extant members of the subtribe Hominina, a branch of the tribe Hominini belonging to the family of great apes. They are characterized by erect posture and bipedal locomotion; high manual dexterity and heavy tool use compared to other animals; and a general trend toward larger, more complex brains and 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 gave rise to anatomically modern Homo sapiens in Africa about 315,000 years ago. They began to exhibit evidence of behavioral modernity around 50,000 years ago. In several waves of migration, anatomically modern humans ventured out of Africa and populated most of the world.
