Homo erectus (/ ˌ h oʊ m oʊ ə ˈ r ɛ k t ə s / lit. ' upright man ') is an extinct species of archaic human from the Pleistocene, spanning nearly 2 million years.It is the first human species to evolve a humanlike body plan and gait, to leave Africa and colonize Asia and Europe, and to wield fire.
In paleoanthropology, the recent African origin of modern humans or the "Out of Africa" theory (OOA) [a] is the most widely accepted [1] [2] [3] model of the geographic origin and early migration of anatomically modern humans (Homo sapiens). It follows the early expansions of hominins out of Africa, accomplished by Homo erectus and then Homo ...
By the 1980s, the growing numbers of H. erectus specimens, particularly in Africa, led to the realization that Asian Homo erectus (H. erectus sensu stricto), once thought so primitive, was in fact more derived than its African counter-parts, [9] which leads into the Out of Africa hypothesis of humans origins.
Homo erectus are the first of our relatives to have human-like body proportions. Kaplan was a co-author of the findings published Thursday in the journal Nature Communications Earth and Environment .
Homo erectus derives from early Homo or late Australopithecus. Homo habilis, although significantly different of anatomy and physiology, is thought to be the ancestor of Homo ergaster, or African Homo erectus; but it is also known to have coexisted with H. erectus for almost half a million years
The remains of Homo erectus have been found on the Indonesian island of Java and elsewhere in Asia as well as Africa. The researchers believe Homo erectus became isolated on the island around 1 ...
They met a lineage of superarchaic hominins that had been separated from African homo lineages since at least 2 Ma ago. [93] Previous studies identified more recent event of admixture. About 350,000 years ago a genome of an "erectus-like" creature was injected into the Denisovan lineage.
However, scientists now have strong genetic evidence that supports an African origin of all Homo sapiens. The model, widely accepted today, is known as the “out of Africa” theory: The distant ...
