Systematics may succinctly be described as "the cradle of comparative biology". It encompasses ☞ characterization, ☞ classification, and nomenclature. The term "taxonomy" is often used interchangeably with systematics. It appears to make more sense to regard taxonomy as the domain within systematics that is concerned with classification. As an aspect of systematics, taxonomy thus constitutes a kind of classification that uses names and by doing so is affected by the ☞ rules of nomenclature. Identification is often considered to be a part of taxonomy but may better be regarded as a ☞ separate kind of undertaking that depends on taxonomy.
