In biology, binomial nomenclature is how species are named. As the word "binomial" suggests, the name of a species is made of two parts: one indicating the genus and one indicating the species. Binomial nomenclature means "two-part name" or "system of two-part names".
The person who popularized this system for use was Swedish botanist and physician Carolus Linnaeus (1707–1778) who tried to name all things in the natural world and gave every species (animal, vegetable or mineral) that he knew a two-part name. This kind of naming had been used before Linnaeus, but before Linnaeus, almost nobody used binomial nomenclature. After Linnaeus, about everybody did.
Value of binomial nomenclature
The value of the binomial nomenclature comes from its economy, its widespread use, and the uniqueness and stability of names in the system. The system replaced the use of Latin descriptive names
- Widespread: worldwide use instead of different local names.
- Clarity: avoids the same term used for different species. Example: "robin" used for different birds in America compared to Europe.
- Uniqueness: One name for a species.
- Stability: the rules favour stability.
- Economy: said to be easier to remember than the previous system.
Where names come from
The names themselves are always treated grammatically as if they were a Latin sentence. This is why the name of a species is sometimes called its "Latin name," but scientists like calling these names scientific names.
