H. erectus in such northerly latitudes may have averaged roughly 150 cm (4 ft 11 in) in height, compared to 160 cm (5 ft 3 in) for more tropical populations. Peking Man lived in a cool, predominantly steppe, partially forested environment, alongside deer, rhinos, elephants, bison, buffalo, bears, wolves, big cats, and other animals.
The tallest Homo sapiens individuals from the Middle Pleistocene of Spain reached 194 cm (76 in) and 174 cm (69 in) for males and females, respectively. [221] Some Homo erectus could be as large as 185 cm (73 in) tall and 68 kg (150 lb) in weight. [222] [223]
Female weight was about the same in contemporaneous H. erectus, but male H. erectus were on average 13 kg (28.7 lb) heavier than P. robustus males. [52] P. robustus sites are oddly dominated by small adults, which could be explained as heightened predation or mortality of the larger males of a group. [53]
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 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.
Jaw of Homo ergaster (KNM ER 992 in the top-right, labelled as Homo erectus in the image) compared to jaws of other members of the genus Homo. It is frequently assumed that the larger body and brain size of H. ergaster, compared to its ancestors, would have brought with it increased dietary and energy needs. [48]
In comparison, present-day humans average 1,350 cc (82 cu in), which is notably smaller. This is because the Cro-Magnon brain, though within the variation for present-day humans, exhibits longer average frontal lobe length and taller occipital lobe height. The parietal lobes, however, are shorter in Cro-Magnons. It is unclear if this could ...
