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]
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.
Of the four species placed within the genus Sinanthropus, the first to be found were remnants of the Peking man (Sinanthropus pekinensis).The first fossil was retrieved by Otto Zdansky (1894-1988) near the village of Chou K'ou-tien (China) after the Swedish Geologist and Archaeologist Johan Gunnar Andersson (1874-1960) and his colleagues instigated the excavations at the beginning of the 1920's.
Homo (from Latin homō '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.
The size of the brain is a frequent topic of study within the fields of anatomy, biological anthropology, animal science and evolution.Measuring brain size and cranial capacity is relevant both to humans and other animals, and can be done by weight or volume via MRI scans, by skull volume, or by neuroimaging intelligence testing.
Nanjing Man is a specimen of Homo erectus (possibly Homo pekinensis [1]) found in China.Large fragments of one male and one female skull and a molar tooth were discovered in 1993 in Hulu Cave (Chinese: 葫芦洞; pinyin: Húlu dòng; lit.
Zhoukoudian Peking Man Site (周口店北京人遗址), also romanized as Choukoutien, is a cave system in suburban Fangshan District, Beijing.It has yielded many archaeological discoveries, including one of the first specimens of Homo erectus (Homo erectus pekinensis), dubbed Peking Man, and a fine assemblage of bones of the giant short-faced hyena Pachycrocuta brevirostris.
The Xujiayao fossils are characterized by a mix of Homo erectus and Homo sapiens features. [9] The skulls also have a thick cranial vault, at the upper range of Homo erectus pekinensis. [9] The maxilla exhibits features more typical of modern Homo sapiens. [9]
