“Homo erectus” means “upright man”. These are extinct species of the archaic humans from the Pleistocene, and their earliest occurrence is close to 2 million years ago. Their last known population is around 117,000–108,000 years ago, H. e. soloensis from Java.

Homo erectus is the most long-lived species of Homo, having survived for almost two million years. By contrast, Homo sapiens emerged about a third of a million years ago. Regarding many archaic humans, there is no definite consensus as to whether they should be classified as subspecies of H. erectus or H. sapiens or as separate species.
