Editing Binomial nomenclature (section)

==Problems==
Binomial nomenclature for species has the effect that when a species is moved from one genus to another, sometimes the specific name or epithet must be changed as well. This may happen because the specific name is already used in the new genus, or to [[Agreement (linguistics)#Gender|agree in gender]] with the new genus if the specific epithet is an adjective modifying the genus name. Some biologists have argued for the combination of the genus name and specific epithet into a single unambiguous name, or for the use of uninomials (as used in nomenclature of ranks above species).<ref>{{cite journal |last=Michener |first=Charles D. |date=1964 |title=The possible use of uninominal nomenclature to increase the stability of names in biology |journal=Systematic Zoology |volume=13 |issue=4 |pages=182–190 |doi=10.2307/2411777 |jstor=2411777}}</ref><ref>{{cite journal |last1=Cantino |first1=P.

Because genus names are unique only within a nomenclature code, it is possible for homonyms (two or more species sharing the same genus name) to happen, and even the same binomial if they occur in different kingdoms. At least 1,258 instances of genus name duplication occur (mainly between zoology and botany).<ref name="hemi">{{cite web |title=HemiHomonym Database |url=http://herba.msu.ru/shipunov/os/homonyms/index.php |website=herba.msu.ru |access-date=17 November 2022 |archive-url=https://web.archive.org/web/20150512143402/http://herba.msu.ru/shipunov/os/homonyms/index.php |archive-date=12 May 2015}}</ref><ref name="HHDB">{{cite journal |last1=Shipunov |first1=Alexey |title=The problem of hemihomonyms and the on-line hemihomonyms database (HHDB) |journal=Bionomina |date=16 January 2013 |volume=4 |issue=1 |pages=65–72 |doi=10.11646/bionomina.4.1.3 |doi-access=free}}</ref>
