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.
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.
INTRODUCTION. 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 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.
Living entirely on the ground and the first to venture out of Africa, Homo ergaster/erectus created the most successful tool ever invented by any hominid and may have been the first to live in bands of hunter gatherers and use fire to cook food.
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. It is variously considered to be (1) a distinct species, perhaps ancestral to the Asian Homo erectus; (2) a subspecies of H. erectus, H. erectus ergaster; or (3) the African variety of H. erectus, with "Homo ...
Compare and contrast the anatomy and material culture of H. habilis, H. erectus, and H. ergaster. Define the term “tool industry” and describe the tools typified by the Oldowan and Acheulean industries. Identify possible correlations between the environment, diet, new behaviors, and brain growth.
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 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.
Homo ergaster. Homo ergaster's dispersal is limited to the continent of Africa, and fossil remains have been found in East Africa at Olduvai Gorge and East Turkana, and in South Africa at Swartkrans.
