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.

H. ergaster is thought to have evolved from either H. habilis or H. rudolfensis in East Africa. However, it is possible that H. habilis may have been the first to leave Africa, after which it may have evolved into a pre- ergaster / erectus form that then moved into Africa and Asia.

Homo ergaster is an extinct hominin that lived in eastern and southern Africa from about 1.8 million years ago (mya) to about 1.3 mya.

H. erectus is what biologists call a chronospecies, a species that changes through time. Homo ergaster is the name given to its earlier phase, which lived mainly in Africa; the later Homo erectus lived mostly in Eurasia.

Jan 3, 2024 · Early African Homo erectus fossils (sometimes called Homo ergaster) are the oldest known early humans to have possessed modern human-like body proportions with relatively elongated legs and shorter arms compared to the size of the torso.

Various fossils found in Eurasia at Dmanisi in the Republic of Georgia may belong to Homo ergaster. These Dmanisi fossils are significant because they currently represent the earliest evidence for the emergence of early humans from Africa into Eurasia 1.75 million years ago.

Homo ergaster, also called "African Homo erectus", is an extinct chronospecies [1] of Homo which lived in eastern and southern Africa during the early Pleistocene, between 1.8 million and 1.3 million years ago.

Homo ergaster is the first Homo that looks much like H. sapiens. A key difference between H. ergaster and earlier hominins is that H. ergaster exhibits substantially less sexual dimorphism in body size. H. ergaster males were only 20 percent larger than females.

Homo ergaster is an extinct species of Homo that lived in eastern and southern Africa from about 1.89 million years ago. Homo Ergaster is widely accepted to be the direct ancestor of later hominids such as Homo heidelbergensis, Homo sapiens, and Homo neanderthalensis rather than Asian Homo erectus.

Homo ergaster includes the early African and Georgian specimens attributed by others to H. erectus and is therefore posited as the ancestor to Homo erectus, Homo heidelbergensis, and Homo sapiens (Wood 1994).
