Homo ergaster is an extinct species or subspecies of archaic humans who lived in Africa in the Early Pleistocene.Whether H. ergaster constitutes a species of its own or should be subsumed into H. erectus is an ongoing and unresolved dispute within palaeoanthropology.
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
This concerns Homo ergaster in particular. [19] [20] One proposal divides Homo erectus into an African and an Asian variety; the African is Homo ergaster, and the Asian is Homo erectus sensu stricto. (Inclusion of Homo ergaster with Asian Homo erectus is Homo erectus sensu lato.
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.
A phylogenetic analysis published in 2017 suggests that H. floresiensis was descended from a species (presumably Australopithecine) ancestral to Homo habilis, making it a "sister species" either to H. habilis or to a minimally habilis-erectus-ergaster-sapiens clade, and its line is older than H. erectus itself.
About 350,000 years ago a genome of an "erectus-like" creature was injected into the Denisovan lineage. With the separation time of about 2 Ma ago and interbreeding that happened 350 ka ago, the two populations involved were more distantly related than any pair of human populations previously known to interbreed.
Between 2 and less than a million years ago, Homo spread throughout East Africa and to Southern Africa (Homo ergaster), but not yet to West Africa. Around 1.8 million years ago, Homo erectus migrated out of Africa via the Levantine corridor and Horn of Africa to Eurasia.
Turkana Boy, also called Nariokotome Boy, is the name given to fossil KNM-WT 15000, a nearly complete skeleton of a Homo erectus youth who lived 1.5 to 1.6 million years ago. This specimen is the most complete early hominin skeleton ever found. [1]
