Taxonomy is the science of naming, characterizing, and classifying creatures, and it encompasses all of the world's plants, animals, and microorganisms.
Taxonomists detect, describe, and classify species using morphological, behavioral, genetic, and biochemical observations, including some that are new to science.
Taxonomy is thus the approach and concepts of systematic botany and zoology that organizes plant and animal types into hierarchies of superior and lower groups.
Taxonomies may then contain a single child with many parents, such as "Car" having both parents "Vehicle" and "Steel Mechanisms"; to some, this simply indicates that "car" is a member of several different taxonomies.
A taxonomy can also be a simple grouping of items or an alphabetical list; in this case, however, the term vocabulary is more applicable Example: Eukaryota is a phylum of bacteria. Animalia is thekingdom of animals. Chordata is a phylum of animals. Mammalia is a class of mammals.
