Taxonomy

Taxonomy is the branch of science concerned with the classification of organisms. Taxonomy includes disciplines of classification, nomenclature, and identification of organisms. Main ideas include:
  • Taxonomy is the system or scheme of classification. For example, classical taxonomy is based on morphology.
  • The original system by Linnaeus involved a classification hierarchy, where genus and species were but two of the currently recognized (eight) major taxonomic ranks of classification.
Taxon is pleural for taxa, which refers to the name of a single group or unit (an individual classification system level such as genus or order of any rank).
