The International Code of Zoological Nomenclature (ICZN) is a widely accepted convention in zoology that rules the formal scientific naming of organisms treated as animals. It is also informally known as the ICZN Code , for its formal author, the International Commission on Zoological Nomenclature (which shares the acronym "ICZN").
In the ICZN, the system is also called binominal nomenclature, [1] "binomi'N'al" with an "N" before the "al", which is not a typographic error, meaning "two-name naming system". [ 2 ] The first part of the name – the generic name – identifies the genus to which the species belongs, whereas the second part – the specific name or specific ...
The ICZN is governed by the "Constitution of the ICZN", which is usually published together with the ICZN Code. [2] Members are elected by the Section of Zoological Nomenclature, [3] established by the International Union of Biological Sciences (IUBS). The regular term of service of a member of the Commission is six years.
Binomial nomenclature, as described here, is a system for naming species. Implicitly, it includes a system for naming genera, since the first part of the name of the species is a genus name. In a classification system based on ranks, there are also ways of naming ranks above the level of genus and below the level of species.
Under the ICZN, two names of the same rank that have the same name-bearing type are objective synonyms, as are two whose name-bearing types are themselves objectively synonymous names; [7] for example, the names Didelphis brevicaudata Erxleben, 1777, and Didelphys brachyuros Schreber, 1778, were both based on a specimen (now in the British Museum of Natural History) described by Seba in 1734 ...

The International Code of Nomenclature for algae, fungi, and plants (ICN or ICNafp) is the set of rules and recommendations dealing with the formal botanical names that are given to plants, fungi and a few other groups of organisms, all those "traditionally treated as algae, fungi, or plants".

By 5 million YBP the larger Canis lepophagus, ancestor of wolves and coyotes, appeared in the same region. [ 1 ] : p58 Around 5 million years ago, some of the Old World Eucyon evolved into the first members of Canis , [ 14 ] and the position of the canids would change to become a dominant predator across the Palearctic .
