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 (until about 1.5 Ma).
The foramen magnum is located inferiorly under the skull, which puts much of the weight of the head behind the spine. The flat human face helps to maintain balance on the occipital condyles . Because of this, the erect position of the head is possible without the prominent supraorbital ridges and the strong muscular attachments found in, for ...
Homo erectus was the first ancient human to migrate out of Africa about 1.9 million years ago. Although Homo erectus had a gait and body size similar to modern humans, researchers think the ...
Peking Man (Homo erectus pekinensis) is a subspecies of H. erectus which inhabited what is now northern China during the Middle Pleistocene. Its fossils have been found in a cave some 50 km (31 mi) southwest of Beijing (then referred to in the West as Peking ), known as the Zhoukoudian Peking Man Site .
Homo erectus lived from about 1.8 Ma to about 70,000 years ago ... The foramen magnum migrated under the skull and more anterior. [130]
The Dmanisi skull, also known as Skull 5 or D4500, is one of five skulls discovered in Dmanisi, Georgia and classified as early Homo erectus.Described in a publication in October 2013, it is estimated to be about 1.8 million years old and is the most complete skull of a Pleistocene Homo species, [1] [2] and the first complete adult hominin skull of that degree of antiquity.
The foramen magnum is a very important feature in bipedal mammals. One of the attributes of a biped's foramen magnum is a forward shift of the anterior border of the cerebellar tentorium; this is caused by the shortening of the cranial base. Studies on the foramen magnum position have shown a connection to the functional influences of both ...
