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 ...
These sites attest that early Homo erectus have crossed the North African tracts, which are usually hot and dry. [4]: 2 There is little time between Homo erectus' apparent arrival in South Caucasus around 1.8 Ma, and its probable arrival in East and Southeast Asia.
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.
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 .
[4] And: "The primary competing scientific hypothesis is currently recent African origin of modern humans, which proposes that modern humans arose as a new species in Africa around 100-200,000 years ago, moving out of Africa around 50-60,000 years ago to replace existing human species such as Homo erectus and the Neanderthals without interbreeding.
Homo erectus was the first ancient human to migrate out of Africa about 1.9 million years ago. Although Homo erectus had a gait and body size similar to modern humans, researchers think the ...
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
