2. 2.1 Taxonomy pg. 98 - 101 Definition: science of classifying organisms (both living & extinct) Purpose of Taxonomy Why do we classify living organisms? 1. to identify organisms 2. to represent evolutionary relationships among them

3. Taxonomic System developed by Carl Linnaeus (1707-1778) in Latin based his classification on structural and physical features the more features organisms have in common, the closer their relationship
