  1. TAXONOMY I Introduction to Botany

  2. Applied Science vs. Pure Science Utilitarian vs. Search for Truth

  3. Taxonomy = naming of taxa taxa = groups of “things” taxon = one group or category

  4. Doctrine of signatures Part of a Utilitarian taxonomic system

  5. Utilitarian Applied Science • Identifying plants • Phenetic (artificial) classifications • Dichotomous keys • what most of us need/want to get from this course (learning how to ID plants using dichotomous keys)

  6. Utilitarian Applied Science • Identifying plants • Phenetic (artificial) classifications • Dichotomous keys • what most of us need/want to get from this course (learning how to ID plants using dichotomous keys)

  7. Applied Science vs. Pure Science Utilitarian vs. Search for Truth

  8. PURE Science • Cladistic systems (phylogenies) focusing on how taxa evolved rather than ID use • monophyletic principles • DEEP GREEN & phyloclades http://tolweb.org/tree?group=life

  9. http://www.nytimes.com/library/national/science/083199sci-evolution-species.htmlhttp://www.nytimes.com/library/national/science/083199sci-evolution-species.html taxonomy changes every day

  10. In the middle of the pure vs useful • devoted to “truth” but also trying to be practical TYPE system. • International Code of Botanical Nomenclature

  11. In the middle of the pure vs useful • TYPE system. • Neoplatonic historical artifact. Ideos • Religious connection = supernatural creationism = Allah or JHWH created each species in separate supernatural acts. • Philosophical approach = variations are degenerate

  12. Darwin changed everything • http://campus.queens.edu/faculty/jannr/darwin.htm

  13. In the middle of the pure vs useful • International Code of Botanical Nomenclature • kingdom • division or phylum • class • order • family • genus (genera) Linne • species Linne • FILE A TYPE SPECIMEN at each taxon but make alltaxa monophyletic!
