  1. Taxonomy And Classification Ms. Politano Zoology

  2. Taxonomy is the science of grouping and naming organisms. • Classification the grouping of • information or objects based on • similarities.

  3. Aristotle • Plant or animal? • If an animal, does it • Fly • Swim • Crawl • Simple classifications • Used common names

  4. Ghost Cat, Devil Cat, Puma, Cougar, Mountain Lion, Florida Panther

  5. Carl Linnaeus • Described organisms with two word names, instead of polynomials as first developed by Aristotle. • Developed binomial nomenclature • First word = genus name • Second word = species name

  6. The genus name is written first (always Capitalized). • The species name is written second (never capitalized). • Example:Felisconcolor or F. concolor • Which is the genus? The species? Binomial Nomenclature

  7. All organisms classified in a hierarchy • Kingdom (broadest) • Phylum • Class • Order • Family • Genus • Species (most specific)

  8. Species vs. Genus • Species A group of similar organisms that produce fertile offspring. • Genus - A group of similar species. The most closely related.

  9. Why is taxonomy useful? • Helps prevent confusion among scientists • Helps to show how organisms are related • Can be used to reconstruct phylogenies – evolutionary histories – of an organism or group

  10. Dichotomous Key • A series of descriptions arranged in pairs that leads you to the identification of an unknown organism.

  11. Activity: Identify an unknown animal • You will be created YOUR own dichotomous key to help identify some unknown creatures. • Remember they should contain simple yes or no questions and need to be on observable characteristcs.
