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.
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.
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.
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.
After 1.5 million years ago (extinction of Paranthropus), all fossils shown are human (genus Homo). After 11,500 years ago (11.5 ka, beginning of the Holocene ), all fossils shown are Homo sapiens ( anatomically modern humans ), illustrating recent divergence in the formation of modern human sub-populations .
The Magdalenian and Epi-Gravettian gave way to Mesolithic cultures as big game animals were dying out and the Last Glacial Period drew to a close. Cro-Magnons were anatomically similar to present-day Europeans, West Asians, and North Africans; however, they were more robust, having larger brains, broader faces, more prominent brow ridges , and ...

The genus Homo evolved from Australopithecus. [7] The earliest record of Homo is the 2.8 million-year-old specimen LD 350-1 from Ethiopia, [8] and the earliest named species is Homo habilis which evolved by 2.3 million years ago. [9] The most important difference between Homo habilis and Australopithecus was a 50% increase in brain size. [10]
