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.
Genetic isolation between races is not complete, but genetic differences may have accumulated that are not (yet) sufficient to separate species. [6] The term is recognized by some, but not governed by any of the formal codes of biological nomenclature. Taxonomic units below the level of subspecies are not typically applied to animals. [7]
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 ...
Differences between these two groups is attributed to phenotypic plasticity and are too few for them to be termed as wholly different species. [7] Emergence of variants of the same species may occur in the same geographical region where different habitats provide distinct ecological niches for these organisms examples of these habitats include ...
A name that was published before 1961 as that of a variety is taken to be the name of a subspecies. A name published after 1960 as that of a variety does not formally exist. In zoology, forms and morphs are used informally if needed, but are unregulated by the ICZN. [citation needed] The bacteriological nomenclature uses the term subspecies ...
These differences arise because there are few available ranks and many branching points in the fossil record. Within species further units may be recognised. Animals may be classified into subspecies (for example, Homo sapiens sapiens, modern humans) or morphs (for example Corvus corax varius morpha leucophaeus, the pied raven).
He found that the majority of genetic differences between humans (85.4 percent) were found within a population, 8.3 percent were found between populations within a race and 6.3 percent were found to differentiate races (Caucasian, African, Mongoloid, South Asian Aborigines, Amerinds, Oceanians, and Australian Aborigines in his study).
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)
