  1. History of Classification

  2. Classification History • Taxonomy: Branch of biology that groups all life according to their characteristics and history • All life on earth is placed into 1 of 6 kingdoms: • Eubacteria • Archaea • Protista • Fungi • Plantae • Animalia

  3. Carolus Linnaeus • Developed classification system based on physical features • Many rules still used today • Binomial Nomenclature: System of giving every organism 2 names • 1st word: Genus (broad) • 2nd word: Species (specific) • Example: House cat • Genus: Felis (cougars, lions, tigers, cheetahs, etc…) • Species: catus

  4. Binomial Format • When Writing: • Genus capitalized • species lowercase • Underlined entirely Ex: Homo sapiens • When Typing: • Same, except use italics Ex: Homo sapiens Bos taurus

  5. Taxa • 7 individual levels (taxa) used to classify organisms Kingdom (broadest) Phylum Class Order Family Genus Species (specific) • Allows relationships to be clearly seen

  6. Cheetah Classification

  7. Red Wolf Classification

  8. Human Classification

  9. Corn Classification

  10. The more levels in common...the more related the species.

  11. You recognize that the fungus is very similar to the infectious fungus known as Malassezia furfur. K: Fungi P: Basidiomycota C: Heterobasidiomycetes O: Tremellales F: Filobasidiaceae G: Malassezia S: furfur How can classification help this patient? Perhaps the Malassezia furfur treatment can be applied to our unknown disease. A patient walks in with an unknown fungal skin disease. You are able to partially classify the new fungus. K: Fungi P: Basidiomycota C: Heterobasidiomycetes O: Tremellales F: Filobasidiaceae G: ????? S: ????? What??? Who Cares!?!?!?!
