  1. Taxonomy The science of naming and classifying organisms.

  2. Classification Scheme Domain—all organisms Kingdom Phylum Class Order Family Genus Species—one type of organism

  3. ClassificationScheme Domain—all organisms Kingdom Phylum Class Order Family Genus Species—one type of organism

  4. Taxonomy cont… • Carolus Linnaeus = Swedish biologist who developed a system for naming and classifying organisms in the 1750’s. • Linnaeus developed binomial nomenclature, which is a two word system for naming organisms.

  5. Scientific Names • Rules: • The first name is always the genus. • The second name is always the species. • The first letter of the genus is always capitalized • The first letter of the species is always lower case. • Italicized or underlined. • Written in Latin. • Homo sapiens

  6. Classification Scheme Kingdom King PhylumPhilip ClassComes OrderOver Family For Genus Good Speciesspaghetti

  11. Housefly Kingdom Animalia PhylumArthropoda ClassInsect OrderDiptera Family Muscidae Genus Musca Speciesdomestica

  12. Dichotomous Key • Method used for classifying an unknown organisms • Contains pairs of contrasting descriptions • After each description, the user will be directed to another pair of descriptions • The organism will be identified by the contrasting descriptions

  13. 1. a. wings covered by an exoskeleton ………go to step 2 b. wings not covered by an exoskeleton ……….go to step 3 2. a. body has a round shape ……….ladybug b.body has an elongated shape ……….grasshopper 3. a. wings point out from the side of the body ……….dragonfly b. wings point to the back of the body ……….housefly

  14. Cladogram • Shows the evolutionary relationships among groups of organisms • Based on ancestral character (common ancestor of group—example bird & mammal have backbone) and derived character (evolved in ancestor of one group but not the other—example feathers on birds but not on mammals)
