A diagram showing the hierarchy of animal classification in taxonomy, with colored boxes arranged from broadest to most specific: domain, kingdom, phylum, class, order, family, genus, and species. — taxonomy Animals and other organisms are classified within a succession of nested groups that ranges from the general to the particular.

While the terms are sometimes used interchangeably, biologists distinguish between taxonomy and systematics based on their scope and focus.

Taxonomy is defined as the theory and practice of classifying organisms. It serves as the methodology and set of principles used to arrange living and extinct organisms into hierarchical groups, providing a uniform system for nomenclature and identification.1

Systematics, conversely, is the broader science of the diversity of organisms. It encompasses classification and naming but also integrates extensive interrelations with fields such as evolution, ecology, genetics, behavior, and comparative physiology.12

In essence, while taxonomy focuses on the mechanics of classification, systematics provides the comprehensive scientific framework for understanding the relationships and evolutionary history of life.1
