Presentation Transcript

  1. Today’s Objectives • TSW be able to recite the levels of taxonomic hierarchy. • TSW be able to name the six kingdoms • TSW be able to identify systematics types.

  2. Taxonomic Hierarchy What is a taxon? What are the 7 levels of hierarchy?

  3. A Note on NOMENCLATURE Carolus Linnaeus Binomial nomenclature system

  4. The Six Kingdom System • Archaebacteria • Eubacteria • Fungi • Protista • Plantae • Animalia

  5. Systematics • Evolutionary systematics • Organisms will resemble each other and their ancestor more than distant organisms • Homologies – result from common ancestry • Analogies – result from common evolutionary pressures

  6. Systematics • Numerical taxonomies • Organisms grouped according to mathematical formulae based on OVERALL similarities • Deal only with closely related taxa

  7. Systematics • Cladistics • Emphasize homologies – synapomorphies • Tries to show evolutionary relationships in a group • Produces cladograms

  8. Sample Cladogram

  9. Systematics • Molecular systematics • Molecular clocks • Compares sequences of amino acids or nitrogenous bases
