1. Taxonomy The science of naming organisms.

2. Aristotle Plant or animal? If an animal, does it –Fly –Swim –Crawl Simple classifications Used common names

3. Carolus Linnaeus Described organisms with two word names, instead of polynomials Developed binomial nomenclature First word = genus name Second word = species name

4. Why binomial nomenclature? Much easier than a 10+ word name under old “polynomial system” Same name no matter where you go Less confusion Binomial = SCIENTIFIC NAME

5. Taxonomic hierarchy Names organisms and their relationships from very broad to very specific Analogous to sorting mail –County, zip code, street, house number

6. All organisms classified in a hierarchy Kingdom (broadest) Phylum Class Order Family Genus Species (most specific)

10. Overview of the 6 kingdoms Plantae –Eukaryotic & Multicellular –Cell walls made of cellulose –Autotrophic Animalia –Eukaryotic & Multicellular –No cell walls –Internal heterotrophs
