Nomenclature of Living Organism: The taxonoimic classification is used to nomenclature of the organism. The most popular method of naming organism is known as binomial system which involves the information of genus and species to name each organism. This system is proposed by carolus Linnaeus where genus and species as first letter and second letter to give the nomenclature of individual organism. For examples, the scientific name of human is Homo sapiens. Here, Homo is the genus and the sapiens is the species. In case the two organism has similar species but they belongs to different sub-species. In these cases, along with species, name of the sub-species is also included. In addition, name of the author appears at the end of biological name, for ex. Scientific name of mango is Mangifera indica Linn. It indicates that mango was first discovered by Linnaeus.
