4. Diversity In Living Organism
Proposed by Carolus Linnaeus.
According to this system of nomenclature, each animal or plant is given two names : the first one is the generic name and the second one is the name of the species.
Scientific names are always in Latin.
The first letter of the generic name is always capitalized and that of the specific name is written in small letter. For example, the scientific name of frog is Rana tigrina, in which Rana is the generic name and tigrina is the name of the species.
