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.
In a sample of 45 Neanderthal long bones from 14 men and 7 women, the average height was 164 to 168 cm (5 ft 5 in to 5 ft 6 in) for males and 152 to 156 cm (5 ft 0 in to 5 ft 1 in) for females. [35] The fossil record shows that adult Neanderthals varied from about 147.5 to 177 cm (4 ft 10 in to 5 ft 10 in) in height. [36]
A modern human (left) and Neanderthal (right) skeleton at the American Museum of Natural History. Neanderthals were short and stocky. Average male body mass index would have been 26.9–28.2 (overweight) using a size of 164 to 168 cm (5 ft 5 in to 5 ft 6 in) and 76 kg (168 lb).
In early Upper Palaeolithic western Europe (before the LGM), 20 men and 10 women were estimated to have averaged 176.2 cm (5 ft 9 in) and 162.9 cm (5 ft 4 in), respectively. This is similar to post-industrial modern northern Europeans.
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).
Scientists said on Wednesday they identified through ancient DNA 13 Homo sapiens skeletal remains in Ilsenhöhle cave, situated below a medieval hilltop castle in the German town of Ra
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 (referred to in the West as Peking upon its first discovery), known as the Zhoukoudian Peking Man Site.
The first member of the genus Homo to be hairless was Homo erectus, originating about 1.6 million years ago. [6] The dissipation of body heat remains the most widely accepted evolutionary explanation for the loss of body hair in early members of the genus Homo, the surviving member of which is modern humans.
