Reconstructed adult body dimensions range from 148–167 cm (4 ft 10 in – 5 ft 6 in) in height and about 50 kg (110 lb) in weight. H. erectus invented the Acheulean industry, a major innovation of large, heavy-duty stone tools, which may have been used in butchery, vegetable processing, and woodworking of maybe digging sticks and spears.
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. [222] Some Homo erectus could be as large as 185 cm (73 in) tall and 68 kg (150 lb) in weight. [223] [224]
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]
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]
The Xiahe mandible shows morphological similarities to some later East Asian fossils such as Penghu 1, [16] [23] but also to Chinese H. erectus. [14] In 2021, Chinese palaeoanthropologist Qiang Ji suggested his newly erected species, H. longi , may represent the Denisovans based on the similarity between the type specimen's molar and that of ...
It is believed that Homo erectus were, anatomically, modern humans as they are very similar in size, weight, bone structure, and nutritional habits. Over time, however, human intelligence developed in phases that is interrelated with brain physiology, cranial anatomy and morphology, and rapidly changing climate and environments.
