3. Aristotle: BC First method of classification 2 major groups Plants - size & structure Animals - where they lived (land or water)

4. Linnaeus: Still used today Based on physical characteristics, close relationships 7 Levels of classification 1. Kingdom 2. Phylum 3. Class 4. Order 5. Family 6. Genus 7. Species
