Such a name is called a binomial name (often shortened to just "binomial"), a binomen, binominal name, or a scientific name; more informally, it is also called a Latin name. In the International Code of Zoological Nomenclature (ICZN), the system is also called binominal nomenclature , [ 1 ] with an "n" before the "al" in "binominal", which is ...
How names are correctly established in the frame of binominal nomenclature [1] How to determine whether a given name is available; Which available name must be used in case of name conflicts (= valid name) How scientific literature must cite names; Zoological nomenclature is independent of other systems of nomenclature, for example botanical ...
homonym: names spelled identically, but, in some codes, names spelled similarly, as defined by the code senior homonym (zoology): the first legitimate use of the name which generally takes priority; junior homonym (zoology), later homonym (botany): a later and generally illegitimate use, though in some circumstances the later name is allowed to ...
These codes differ in terminology, and there is a long-term project to "harmonize" this. For instance, the ICN uses "valid" in "valid publication of a name" (=the act of publishing a formal name), with "establishing a name" as the ICZN equivalent. The ICZN uses "valid" in "valid name" (="correct name"), with "correct name" as the ICN equivalent ...
The binomial name often reflects limited knowledge or hearsay about a species at the time it was named. For instance Pan troglodytes, the chimpanzee, and Troglodytes troglodytes, the wren, are not necessarily cave-dwellers. Sometimes a genus name or specific descriptor is simply the Latin or Greek name for the animal (e.g. Canis is Latin for ...
It consists of the name of the genus followed by a "specific epithet". Binomial names must be chosen so that no two organisms have the same name; this means that scientists can use Leptinotarsa decemlineata to refer to the Colorado potato beetle without ambiguity. [a] Binomial names are written in Latin, or
Gene nomenclature is the scientific naming of genes, the units of heredity in living organisms. It is also closely associated with protein nomenclature, as genes and the proteins they code for usually have similar nomenclature.
An "authority" may be placed after a scientific name. [94] The authority is the name of the scientist or scientists who first validly published the name. [ 94 ] 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 ]
