Compared to earlier Homo, H. erectus has smaller teeth, thinner enamel, and weaker mandibles (jawbone), likely due to a greater reliance on tool use and food processing. [52] The brain size of H. erectus varies considerably, but is generally smaller in H. erectus sensu lato, as low as 546 cc (33.3 cu in) in Dmanisi skull 5. [53]
KNM-ER 3883 is a significant fossil specimen of early African Homo erectus, dating to approximately 1.5–1.6 million years ago.This cranium, discovered in Kenya, has an endocranial volume exceeding 800 cc, which is substantially larger than earlier Homo species and suggests a notable increase in brain size.
D4500's features are very rare compared to early Homo in that it had a small braincase yet an unusually large prognathic face. [2] "Skull 5" has an accompanying mandible, D2600, which was found in 2000. In 1999 two other skulls had been found at the same site—D2280 and D2282. D2280 was a near-complete brain-case with 780 cc brain-size.
[8] [9] Characteristics such as a supraorbital torus, or prominent eyebrow ridge, and flat face also makes Homo erectus distinguishable. Their brain size substantially sets them apart from closely related species, such as H. habilis, as seen by an increase in average cranial capacity of 1000 cc. Compared to earlier species, H. erectus developed ...
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 .
The scientific community believe a small species of human known as homo floresiensis once lived on the island of Flores, Indonesia, around 50,000 years ago.But one professor thinks the apelike ...
Homo (from Latin homÅ 'human') is a genus of great ape (family Hominidae) that emerged from the genus Australopithecus and encompasses only a single extant species, Homo sapiens (modern humans), along with a number of extinct species (collectively called archaic humans) classified as either ancestral or closely related to modern humans; these include Homo erectus and Homo neanderthalensis.
