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.
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 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.
The researchers believe Homo erectus became isolated on the island around 1 million years ago and underwent a dramatic reduction in body size during a period of around 300,000 years.
Homo habilis could have developed some baseline behavioural flexibility prior to its expansion into the peripheries (such as encroaching into the predatory guild [45] [46]). This flexibility could then have been positively selected and amplified, leading to Homo erectus ' adaptation to the peripheral open habitats. [47]
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
Claims for the earliest definitive evidence of control of fire by a member of Homo range from 1.7 to 2.0 million years ago . [1] Evidence for the "microscopic traces of wood ash" as controlled use of fire by Homo erectus, beginning roughly 1 million years ago, has wide scholarly support.
Half a million years ago, Homo erectus first migrated out from Africa to Europe and Asia. They settled becoming Neanderthals in Europe. 200,000 years ago, there was a second migration from Africa, this time by Homo sapiens , the encroached upon the pre-existing species with superior weapons, better organization and more numbers and eventually ...
