人類はいつ誕生した
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. Humans began to exhibit evidence of behavioral modernity around 50,000 years ago, and in several waves of migration, they ventured out of Africa and populated most of the world.
