Binomial nomenclature is a system to give scientific names to species of all living things. It was given by Carolus Linnaeus.
According to this system, each organism is given a two part Latin name. The first part tells the genus and called the
generic name. The second part refers to the specie name of that organism and is called the specific name. The first letter of the generic name is always written in capitals but the specific name starts with a small letter. Scientific names are italicized while printing and underlined when written, e.g. Scientific name of humans is Homo sapiens, where Homo is the genus to which sapiens specie belongs.
