Homo erectus
Homo erectus (meaning ""upright man"", from the Latin ērigere, ""to put up, set upright"") is an extinct species of hominid that lived throughout most of the Pleistocene geological epoch. Its earliest fossil evidence dates to 1.9 million years ago and the most recent to 70,000 years ago. Its extinction is linked by some scientists to the Toba super-eruption catastrophe, but no sufficient case has been made to date for the idea. It is generally thought that H. erectus originated in Africa and spread from there, migrating throughout Eurasia as far as Georgia, India, Sri Lanka, China and Java. But other scientists posit that the species rose first, or separately, in Asia.Debate also continues about the classification, ancestry, and progeny of Homo erectus, especially vis-à-vis 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.And there is another view—an alternative to 1): some palaeoanthropologists consider H. ergaster to be a variety, that is, the ""African"" variety, of H. erectus, and they offer the labels ""Homo erectus sensu stricto"" (strict sense) for the Asian species and ""Homo erectus sensu lato"" (broad sense) for the greater species comprising both Asian and African populations.A new debate appeared in 2013, with the documentation of the Dmanisi skulls. 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 erectus.
