Homo erectus (meaning "upright man") is an extinct species of archaic humans that lived throughout most of the Pleistocene geological epoch. Its earliest fossil evidence dates to 1.9 million years ago. It likely originated in East Africa and spread from there, beginning 1.8 million years ago, migrating throughout Eurasia.[2][3]

Early Pleistocene – Late Pleistocene[1]There is an ongoing debate regarding the classification, ancestry, and progeny of Homo erectus, especially in relation to Homo ergaster, with two major positions: 1) H. erectus is the same species as H. ergaster, and thereby H. erectus is a direct ancestor of the later hominins including Homo heidelbergensis, Homo neanderthalensis, and Homo sapiens; or, 2) it is in fact an Asian species distinct from African H. ergaster.[2][4][5] There is also another view—an alternative to 1): some paleoanthropologists consider H. ergaster to be a variety, that is, the "African" variety, of H. erectus; the labels "Homo erectus sensu stricto" (strict sense) for the Asian species and "Homo erectus sensu lato" (broad sense) have been offered for the greater species comprising both Asian and African populations.[6][7]
H. erectus in the narrow sense (the Asian species) was extinct by 140,000 years ago.[1]
A new debate appeared in 2013, with the documentation of the Dmanisi skulls.[8] Considering the large morphological variation among all Dmanisi skulls, researchers now suggest that several early human ancestors variously classified, for example, as Homo ergaster, or Homo rudolfensis, and perhaps even Homo habilis, should instead be designated as Homo There is an ongoing debate regarding the classification, ancestry, and progeny of Homo erectus, especially in relation to Homo ergaster, with two major positions:
