Binomial Nomenclature
Binomial nomenclature is the system of naming each species using two words. It is associated with the work of Carolus Linnaeus.
The two components are:
- Generic name: Identifies the genus.
- Specific epithet: Distinguishes the species within that genus.
For example, the scientific name of mango is Mangifera indica.
- Mangifera is the generic name.
- indica is the specific epithet.
Together, the two words form the scientific name of the species.
Rules for Writing Scientific Names
- Scientific names are generally Latin or Latinised.
- The generic name begins with a capital letter.
- The specific epithet begins with a lowercase letter.
- When printed, the two words are written in italics.
- When handwritten, the two words are underlined separately.
Examples
- Mango: Mangifera indica
- Human: Homo sapiens
- Housefly: Musca domestica
Why Is Binomial Nomenclature Important?
Common names can vary between languages and regions. Scientific names provide a standard naming system that helps scientists communicate clearly about organisms.
Key Takeaway
Each species has a two-part scientific name consisting of a generic name and a specific epithet.
