Q What is signifying by binomial nomenclature and what are its basic rules?
Scientific nomenclature of a species must have at least two names one that classifies it as genus and the other that identifies it as species. The name related to genus is the first and must begin in uppercase the other following names must be written in lowercase. Besides this rule scientific names of species must stand out and be written either in underlined or italics or still bolded or between quotation marks.
For example, the scientific name of the human species is "Homo sapiens" indicating that it belongs to the genus Homo.
Scientific nomenclature of species is important because it universalizes the way to demote to a species making it easier for people of different languages and cultures to understand each other. Same species that have extremely different names in different regions of the planet can be identified easily by their scientific binomial name.
