Binomial naming system;
The binomial naming system is the system used to name species. Each species is given a name that consists of two parts. The first part is the Genus to which the species belongs and the second part is the species name.
For example, Apis mellifera (the honey bee). The honey bee belongs to the Genus Apis and has a scientific name of Apis mellifera.
The binomial naming system was first uniformly used by Carl Linnaeus.
