Homo (from Latin homÅ '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.
LD 350-1 is the earliest known specimen of the genus Homo, dating to 2.75–2.8 million years ago (mya), found in the Ledi-Geraru site in the Afar Region of Ethiopia.The specimen was discovered in silts 10 m (33 ft) above the Gurumaha Tuff section of the site [1] [2] by Ethiopian palaeoanthropologist Chalachew Seyoum on 29 January 2013.
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. It is currently unassigned to a species, and it is unclear if it represents the ancestor to H. habilis and H. rudolfensis, which are estimated to have evolved around 2.4 Ma. [36]
Graecopithecus is an extinct genus of hominid that lived in southeast Europe during the late Miocene around 7.2 million years ago. Originally identified by a single lower jawbone bearing teeth found in Pyrgos Vasilissis, Athens, Greece, in 1944, [1] other teeth were discovered from Azmaka quarry in Bulgaria in 2012. [2]
The genus Homo has been taken to originate some two million years ago, since the discovery of stone tools in Olduvai Gorge, Tanzania, in the 1960s. Homo habilis (Leakey et al., 1964) would be the first "human" species (member of genus Homo) by definition, its type specimen being the OH 7 fossils.
It is most likely that the australopithecines, dating from 4.4 to 3 Mya, evolved into the earliest members of genus Homo. [ 22 ] [ 23 ] In the year 2000, the discovery of Orrorin tugenensis , dated as early as 6.2 Mya, briefly challenged critical elements of that hypothesis, [ 24 ] as it suggested that Homo did not in fact derive from ...
Human evolution is the evolutionary process that led to the emergence of anatomically modern humans, beginning with the evolutionary history of primates – in particular genus Homo – and leading to the emergence of Homo sapiens as a distinct species of the hominid family, the great apes.
Genus Homo is assumed to have emerged by around 2.8 million years ago, with Homo habilis being found at Lake Turkana, Kenya. The delineation of the "human" genus, Homo , from Australopithecus is somewhat contentious, for which reason the superordinate term "hominin" is often used to include both.
