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.
[16] [17] The relative lightness of female compared to male skin in a given population may be due to the greater need for women to produce more vitamin D during lactation. [18] The sweat glands in humans could have evolved to spread from the hands and feet as the body hair changed, or the hair change could have occurred to facilitate sweating.
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).
Homo erectus had longer legs and shorter arms, revealing a transition to obligate terrestriality, though it remains unclear how this change in relative leg length might have been an advantage. [61] Sheer body size, on the other hand, seems to have allowed for better walking energy efficiency and endurance . [ 62 ]
Yuanmou Man (simplified Chinese: 元谋人; traditional Chinese: 元謀人; pinyin: Yuánmóu Rén, Homo erectus yuanmouensis) is a subspecies of H. erectus which inhabited the Yuanmou Basin in Yunnan Province, southwestern China, roughly 1.7 million years ago. It is the first fossil evidence of humans in China, though they probably reached the ...
A recent analysis of fossils belonging to Homo floresiensis found at the Mata Menge site on Flores supports the idea that the hobbits were a dwarfed version of the extinct species Homo erectus.
They are believed to have begun approximately 2 million years ago with the early expansions out of Africa by Homo erectus. This initial migration was followed by other archaic humans including H. heidelbergensis , which lived around 500,000 years ago and was the likely ancestor of Denisovans and Neanderthals as well as modern humans.
Ape to Man: Theory of evolution did draw criticism from the scientific community about speculative claims made by the producers of the documentary about evidence gained from ancient fragments [5] The specific points noted that were speculative were: Why did Homo erectus develop complex sweat glands, causing gradual hairlessness of the skin?
