Homo ergaster, also Homo erectus ergaster or African Homo erectus is an extinct chronospecies of the genus Homo that lived in eastern and southern Africa during the early Pleistocene, between about 1.9 million and 1.4 million years ago.
Originally proposed as a separate species, H. ergaster is now mostly considered either an early form, or an African variety, of H. erectus.
The binomial name was published in 1975 by Groves and Mazák. The specific epithet, “ergaster”, is derived from the Ancient Greek “workman”, in reference to the advanced lithic technology developed by the species, thereby introducing the Acheulean industry.
KNM-ER 2598, a “H. erectus-like” occipital bone stands as the earliest evidence for H. erectus in Africa at approximately 1.9 million years ago (contemporary with Homo rudolfensis). There is a fossil gap between 1.9 and 1.6 million years ago, Homo ergaster KNM ER 3733 or Hominid Homo ergaster is the oldest known H. ergaster skull dated to about 1.6 million years ago. Its survival past 1.4 million years ago is uncertain, again due to a fossil gap, the next available African fossils allowing reliable morphological analysis are those of Homo rhodesiensis (African H. heidelbergensis), at 0.6 million years ago.
Homo ergaster KNM-ER 3733 or Hominid Homo ergaster is a find of a near-complete cranium. Its brain size is about 850cc. KNM-ER 3733 or Hominid Homo ergaster was compared to male fossils KNM ER 3883 and KNM WT 15000 (Turkana Boy), who were also found at the Koobi Fora site, and because of this, is said to be female. The features of KNM-ER 3733 or Hominid Homo ergaster are less robust compared to the two male crania. It is considered an adult because of the extensive wear of its teeth, the fact that its third molars were present before the individual died, and because its cranial sutures were fully fused, which is only possible in adult specimen.
