Darajar tsarin nomenclature na binomial ya samo asali ne daga tattalin arzikinta, amfani da shi yaduwa, da kuma bambancin da kwanciyar hankali na sunayen da lambobin Zoological da Botanical, Bacterial da Viral Nomenclature ke bayarwa:

Aikace-aikacen nomenclature na binomial yanzu ana sarrafa shi ta hanyoyi daban-daban na ka'idojin da aka amince da su a duniya, wanda biyu mafi mahimmanci sune International Code of Zoological Nomenclature (ICZN) don dabbobi da kuma International Code of Nomencleture don algae, fungi, da tsire-tsire ('ICN' ko ICN). Kodayake ka'idodin da ke tattare da sunan binomial sun zama ruwan dare ga waɗannan lambobin biyu, akwai wasu bambance-bambance a cikin kalmomin da suke amfani da su da kuma takamaiman dokokinsu.

Carl Linnaeus (1707-1778), masanin ilimin tsire-tsire na Sweden, ya kirkiro tsarin zamani na binomial nomenclature

Kafin karɓar tsarin binomial na zamani na nau'ikan suna, sunan kimiyya ya ƙunshi sunan gama gari tare da takamaiman sunan da ya kasance daga kalma ɗaya zuwa kalmomi da yawa. Tare sun kafa tsarin nomenclature na polynomial. Wadannan sunayen suna da ayyuka biyu daban-daban.

Irin waɗannan "sunayen polynomial" na iya kama da binomials, amma sun bambanta sosai. Misali, Gerard's herbal (kamar yadda Johnson ya gyara) ya bayyana nau'ikan gizo-gizo daban-daban: "Na farko ana kiransa Phalangium ramosum, Branched Spiderwort; na biyu, Phalangius non ramosum، Unbranched Spiderwort.

Ya kasance a cikin Linnaeus's 1753 Species Plantarum cewa ya fara amfani da kalma ɗaya mai ban sha'awa (sunan maras muhimmanci) bayan sunan gama gari (sunan jinsin) a cikin tsarin nomenclature na binomial.

  • Economy. Compared to the polynomial system which it replaced, a binomial name is shorter and easier to remember.[5] It corresponds to the noun-adjective form many vernacular names take to indicate a species within a group (for example, 'brown bear' to refer to a particular type of bear),[6] as well as the widespread system of family name plus given name(s) used to name people in many cultures.
  • Widespread use. The binomial system of nomenclature is governed by international codes and is used by biologists worldwide. A few binomials have also entered common speech, such as Homo sapiens, E. coli, Boa constrictor, Tyrannosaurus rex, and Aloe vera.
  • Uniqueness. Provided that taxonomists agree as to the limits of a species, it can have only one name that is correct under the appropriate nomenclature code, generally the earliest published if two or more names are accidentally assigned to a species. This means the species a binomial name refers to can be clearly identified, as compared to the common names of species which are usually different in every language.[6] However, establishing that two names actually refer to the same species and then determining which has priority can sometimes be difficult, particularly if the species was named by biologists from different countries. Therefore, a species may have more than one regularly used name; all but one of these names are "synonyms".[7] Furthermore, within zoology or botany, each species name applies to only one species. If a name is used more than once, it is called a homonym.
