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.

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.

Homo ergaster was first proposed as a new species in 1975 after scientists re-examined a fossil jaw previously identified as Homo habilis. Colin Groves and Vratislav Mazák noticed some unique features about this jaw that made it different to our other human ancestors.

As mentioned, the African form of the “erectus grade” is termed Homo ergaster. PHYLOGENY H. ergaster is thought to have evolved from either H. habilis or H. rudolfensis in East Africa.

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.

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 erectus or “upright/standing man” evolved from H. habilis. H. erectus became bipedal at least 3 to 4 million years ago and first moved out of Africa about 1.8 million years ago. H. erectus is what biologists call a chronospecies, a species that changes through time.

Homo ergaster is a fossil hominin species often used to describe a subset of fossils within Homo erectus. Proponents generally allocate early African Homo erectus fossils dating from c. 1.8–1.4 Ma to Homo ergaster, mainly on the basis of smaller, more

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.

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.
