Question

how animals are classified according to the traditional method​

Answer 1

Traditional classification

In the 18th century Carolus Linnaeus revolutionized the field of natural history by introducing a formalized system of naming organisms, what we call a taxonomic nomenclature. He divided the natural world into 3 kingdoms and used five ranks: class, order, genus, species, and variety. He also introduced the system of binomial nomenclature, in which every species has an internationally recognized two-part name.

Since Linneaus’ time, other ranks have been added to the taxonomic nomenclature system. The major taxonomic ranks are Kingdom, Phylum, Class, Order, Family, Genus, Species. These ranks have been used to describe and understand major animal groups for a long time, and many people are taught about animal natural history through these traditional ranks. We grow up referring birds to “Class Aves,” snakes to “Class Reptilia,” etc.
