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 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 emerges just after 2 million years ago. [11] Early H. erectus would have lived face to face with H. habilis in East Africa for nearly half a million years. [12] The oldest Homo erectus fossils appear almost contemporaneously
Before Homo sapiens, Homo erectus had already spread throughout Africa and non-Arctic Eurasia by about one million years ago. The oldest known evidence for anatomically modern humans (as of 2017) are fossils found at Jebel Irhoud, Morocco, dated about 360,000 years old. [2]
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.
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 ...
