Genus (/ ˈ dʒ iː n ə s /; pl.: genera / ˈ dʒ ɛ n ər ə /) is a taxonomic rank above species and below family as used in the biological classification of living and fossil organisms as well as viruses. [1] In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus.
The basic ranks are species and genus. When an organism is given a species name it is assigned to a genus, and the genus name is part of the species name. The species name is also called a binomial, that is, a two-term name. For example, the zoological name for the human species is Homo sapiens. This is usually italicized in print or underlined ...

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.
For example, in 1758, Linnaeus gave the Asian elephant the scientific name Elephas maximus, so the name is sometimes written as "Elephas maximus Linnaeus, 1758". [95] The names of authors are often abbreviated: the abbreviation L. , for Linnaeus, is commonly used.
An example of a long-established taxon that is not also a clade is the class Reptilia, the reptiles; birds and mammals are the descendants of animals traditionally classed as reptiles, but neither is included in the Reptilia (birds are traditionally placed in the class Aves, and mammals in the class Mammalia).
