Practice question

Principle of priority provides objective criterion for choosing correct name when multiple synonyms exist for same taxon. Earliest validly published name that satisfies code requirements takes precedence, irrespective of later widespread usage or descriptive appropriateness. Later competing names become heterotypic synonyms and are rejected. Starting dates anchor priority — 1753 for plants, 1758 for animals. Codes allow conservation of well-known later names nomina conservanda to avoid destabilizing disruption. Priority prevents arbitrary name changes and promotes chronological fairness in taxonomy. Clarity on this principle prevents confusion between in-situ and ex-situ methods often interchanged in examination options.
