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.
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.
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.
Sumatran orangutan (Pongo abelli) Hominoidea is a superfamily of primates. Members of this superfamily are called hominoids or apes, and include gorillas, chimpanzees, orangutans, gibbons, bonobos, and humans. Hominoidea is one of the six major groups in the order Primates. The majority are found in forests in Southeastern Asia and Equatorial Africa, with the exception of humans, which have ...
The name Homo of the biological genus to which humans belong is Latin for 'human'. [e] It was chosen originally by Carl Linnaeus in his classification system. [f] The English word human is from the Latin humanus, the adjectival form of homo. The Latin homo derives from the Indo-European root * dhghem, or 'earth'. [220]
Carl Linnaeus coined the name Homo sapiens. All modern humans are classified into the species Homo sapiens, coined by Carl Linnaeus in his 1735 work Systema Naturae. [9] The generic name "Homo" is a learned 18th-century derivation from Latin homō, which refers to humans of either sex. [10] [11] The word human can refer to all members of the ...
Most of them were coined since the mid 20th century in imitation of Homo sapiens in order to make some philosophical point (either serious or ironic), but some go back to the 18th to 19th century, as in Homo aestheticus vs. Homo oeconomicus; Homo loquens is a serious suggestion by Herder, taking the human species as defined by the use of ...
[7] The genus Homo evolved from Australopithecus. [8] The earliest record of Homo is the 2.8 million-year-old specimen LD 350-1 from Ethiopia, [9] and the earliest named species is Homo habilis which evolved by 2.3 million years ago. [10] The most important difference between Homo habilis and Australopithecus was a 50% increase in brain size. [11]
