The process of classification aids in the standardization of the naming of living organisms by which a particular organism is known by a universal name.
In 1753, Carolus Linnaeus proposed the Binomial System of Nomenclature for assigning scientific names to plants and animals.
According to the Binomial Nomenclature, each organism bears two names: the first is the generic name, and the second is a specific epithet.
Lion, Tiger, and Panther belong to the same genus, i.e., Panthera, but are different species.
Lion belong to the species Panthera leo
Hence, the zoological name of the lion is Panthera leo.
