The informal taxonomic rank of race is variously considered equivalent or subordinate to the rank of subspecies, and the division of anatomically modern humans (H. sapiens) into subspecies is closely tied to the recognition of major racial groupings based on human genetic variation. A subspecies cannot be recognized independently: a species ...
It has been used as a higher rank than strain, with several strains making up one race. [ 2 ] [ 3 ] Races may be genetically distinct populations of individuals within the same species , [ 4 ] or they may be defined in other ways, e.g. geographically, or physiologically. [ 5 ]
In North America, the species Rangifer tarandus (locally known as caribou), [46] [47] was subdivided into five subspecies [note 2] by Banfield in 1961. [48] Caribou are classified by ecotype depending on several behavioural factors – predominant habitat use (northern, tundra, mountain, forest, boreal forest, forest-dwelling), spacing ...
Genetic studies of traits and populations have been used to justify social inequalities associated with race, [7] despite the fact that patterns of human variation have been shown to be mostly clinal, [8] with human genetic code being approximately 99.6% – 99.9% identical between individuals and without clear boundaries between groups.

To indicate the rank of the infraspecific name, a "connecting term" is needed. Thus Poa secunda subsp. juncifolia, where "subsp". is an abbreviation for "subspecies", is the name of a subspecies of Poa secunda. [19] Hybrids can be specified either by a "hybrid formula" that specifies the parentage, or may be given a name.
Subspecies is abbreviated as subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology , under the International Code of Zoological Nomenclature , the subspecies is the only taxonomic rank below that of species that can receive a name.
Race is a categorization of humans based on shared physical or social qualities into groups generally viewed as distinct within a given society. [1] The term came into common usage during the 16th century, when it was used to refer to groups of various kinds, including those characterized by close kinship relations. [2]
In case of humans, the sentence "the human races all form part of one single subspecies", meaning that they are not as wide apart to be considered different subspecies, makes scientific sense, and so by implication, the termina "subspecies" and "race" mean something different.--2001:A60:159F:A401:58D9:7B9E:2E9E:966D 14:00, 28 August 2014 (UTC)
