Taxonomy

Explanation:

Taxonomy is the science of identifying different organisms, living and extinct, by classifying and naming them. To achieve this goal taxidermists consider genetics, biochemistry, behaviors, and morphology and resume this information into the species name. Domain, Kingdom, Phylum, Class, Order, Family, Genus, and Species are the taxonomic categories used from general to particular.
