The first member of the genus Homo to be hairless was Homo erectus, originating about 1.6 million years ago. [6] The dissipation of body heat remains the most widely accepted evolutionary explanation for the loss of body hair in early members of the genus Homo, the surviving member of which is modern humans.
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.
Java Man (Homo erectus erectus, formerly also Anthropopithecus erectus or Pithecanthropus erectus) is an early human fossil discovered in 1891 and 1892 on the island of Java (Indonesia). Estimated to be between 700,000 and 1,490,000 years old, it was, at the time of its discovery, the oldest hominid fossil ever found, and it remains the type ...
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.
H. habilis is intermediate between Australopithecus afarensis and H. erectus, and there have been suggestions to re-classify it within genus Australopithecus, as Australopithecus habilis. LD 350-1 is now considered the earliest known specimen of the genus Homo, dating to 2.75–2.8 Ma, found in the Ledi-Geraru site in the Afar Region of Ethiopia.
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]
The extinct species Homo floresiensis has long puzzled experts. A new analysis offers clues to the mystery of this tiny oddball’s place on the human family tree.
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 ...
