Homo Erectus is an extinct species of archaic human, whose name means “upright man.” It is used in anthropology to refer to a well-documented fossil hominin that lived roughly 1.9 million to 110,000 years ago, with notable cranial features and early tool use. In scholarly contexts, the term combines a genus (Homo) and species (Erectus) designation and is pronounced as a two-word proper noun.
