Full Answer. Also called a dichotomous key, a taxonomic key gives users a systematic and reproducible way to identify items and organisms. It is used for a variety of purposes, such as identifying unknown organisms to a certain taxonomic level (e.g. family, genus and species) and identifying rocks or minerals.
The first part of a binomial is the generic name, the genus to which the species belongs. The second part is either called the specific name (a term used only in zoology) or the specific epithet (the term used in botany, which can also be used in zoology). For example, Boa constrictor is one of four species of the Boa genus. While the genus gets capitalized, the specific epithet does not.
