Taxonomy and Classification

Taxonomy is The classification of organisms in an ordered system that indicates natural relationships.

Classification is The systematic grouping of organisms into categories on the basis of evolutionary or structural relationships between them 1. Kingdom 2. Phylum 3. Class 4. Order 5. Family 6. Genus 7. Species

Some History Aristotle: Greek philosopher (384 – 322 BC) Began classifying organisms into 3 distinct groups: Of the air  flying Of the water  swimming Of the land  walking What’s wrong with this system?

Name this Animal

Carolus Linnaeus Swedish botanist 1707 – 1778 Developed system of binomial nomenclaturebinomial nomenclature –Bi = two –Nomial= name –Nomenclature = system of assigning names Two-name system still in use today Consists of 7 categories Latin-based -- Why Latin? –Universally accepted language –Language that’s not used anymore

Name this Animal Mountain lion Puma Cougar Catamount Panther Ghost Cat

Name this Animal The Scientific or Latin Name for this species is Felis concolor (Always italics or underlined) Felis = Genus (always capitalized) concolor = Species (Always lower case)
