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. What is a taxon? What are the 7 levels of hierarchy?
Taxonomic Hierarchy
What is a taxon?
What are the 7 levels of hierarchy?
A taxon is a group of animals that share a particular set of characteristics.
Kingdom, phylum, class, order, family, genus, and species.

3. Carolus Linnaeus Binomial nomenclature system
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
