Subspecies
Subspecies
Subspecies (pronunciation: sʌbˈspiːʃiːz) is a term used in taxonomy, the science of classification, to refer to a category within a species. The term is used to denote a distinct variation within a species that is geographically or otherwise isolated from other populations of the same species and exhibits characteristics that differentiate it from other populations.
Etymology
The term "subspecies" is derived from the Latin words "sub" meaning "under" or "below", and "species" meaning "kind" or "sort". It was first used in the context of biological classification in the 18th century.
