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.
It was conjectured that the categorical differences seen in for instance the mandibular and dental features of the crania from Dmanisi, may be ascribed to taxonomic diversity, as opposed to all five deriving from the same H. erectus lineage. [5] The rather small braincase of D2700 was believed to be at odds with the characteristics of H. erectus.
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.

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
SK 847, a fragmentary skull commonly classified as Homo habilis or Homo ergaster, referred to Homo gautengensis by Curnoe. Palaeoanthropologists vary in their recognition of which hominin fossil represents the earliest record of the genus Homo (and in what range of morphology the genus should encompass). Most of the fossils contending for the ...
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 ...
