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.
Leakey named it "Chellean Man", in reference to the Oldowan tools found at the site, which were then referred to by the now-obsolete name Chellean.Heberer (1963) provisionally named a new species Homo leakeyi based on the specimen in honor of Leakey, [3] but most subsequent workers have regarded it as Homo ergaster, or as Homo erectus (H. ergaster is sometimes regarded as a subspecies of H ...
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.
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
KNM-ER 3883 is a significant fossil specimen of early African Homo erectus, dating to approximately 1.5–1.6 million years ago.This cranium, discovered in Kenya, has an endocranial volume exceeding 800 cc, which is substantially larger than earlier Homo species and suggests a notable increase in brain size.
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.

Java Man (Homo erectus erectus, formerly also Anthropopithecus erectus or Pithecanthropus erectus) is an early human fossil discovered in 1891 and 1892 on the island of Java (Indonesia). Estimated to be between 700,000 and 1,490,000 years old, it was, at the time of its discovery, the oldest hominid fossil ever found, and it remains the type ...
