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 Xujiayao and Xuchang material are known for their large skulls. [2] Xu and Bae distinguished H. juluensis by a low and wide skull, large brain size (over 1,000 cc), a small and inward mastoid part of the temporal bone, a depression over the parietal bone, defined temporal lines, a high squamous part of temporal bone, an ovoid ear canal, a Neanderthal-like bony labyrinth (in the ear), a ...
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.
Archaic humans [a] is a broad category denoting all species of the genus Homo that are not Homo sapiens (modern humans), which are sometimes also called Homo sapiens sapiens, in which case the singular use of sapiens has been applied to some archaic humans as well.
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]
“Humans changed the horse genome stunningly quickly, perhaps because we already had experience dealing with animals,” said Laurent Frantz, who studies the genetics of ancient creatures at the ...
He studies the origins of Homo sapiens, origin of the genus Homo, the fate of the Neanderthals, hybridization among extant mammals, and late Australopithecus. [4] Holliday got his B.A. in anthropology from Louisiana State University (1988) and M.A. (1991) and Ph.D. (1995) in anthropology in the University of New Mexico. [4]
The discovery of LD 350-1, the oldest Homo specimen, dating to 2.8 mya, in the Afar Region of Ethiopia may indicate that the genus evolved from A. afarensis around this time. This specimen was initially classified as Homo sp., [ 23 ] though subsequent studies have suggested that it also shares characteristics with Australopithecus and that it ...
