Taxonomy Learning Objectives • Define taxonomy • Understand the importance of a standardized taxonomic system
Taxonomy – the branch of biology that classifies and names living things • Uses characteristics of organisms and a universal system – Every organism has a specific name – Organisms are assigned to levels of classification
Common Name vs. Scientific Name Common name – name given to an organism by the people of a certain area • Causes great deal of confusion • Examples: – Mountain lion – Puma – Cougar
