Unit 10 classification

  1. 1. Bellringer: Monday, March 17, 2014 What is the name of this animal? a. Puma b. Cougar c. Mountain lion d. Panther All of the above…these are common names for the same animal.
  2. 2. Objective •We will define and recognize the importance of taxonomy
  3. 3. Anticipatory Set
  4. 4. What is the impact of having misleading names? Anticipatory Set
  5. 5. To avoid confusion caused by regional names, biologists use a classification system to group organisms in an organized and logical manner and to assign names.
  6. 6. What is taxonomy? •It’s the science of naming and classifying organisms.
  7. 7. What is Classification? It’s the grouping of objects or information on the basis of similarities.
  8. 8. The classification system: • Domain Dear • Kingdom King • Phylum Philip • Class came • Order over • Family from • Genus Great • Species Spain
  9. 9. Hierarchical Classification • Taxonomic categories • Kingdom includes all the phyla • Phylum includes all the classes • Class includes all the orders • Order includes all the families • Family includes all the genera • Genus includes all the species • Species Each level is called a taxon
  10. 10. Human Classification • Domain Eukarya • Kingdom Animalia • Phylum Chordata • Class Mammalia • Order Primates • Family Hominidae • Genus Homo • Species sapiens
  11. 11. Work with your partner to create your own pneumonic for remembering the levels of classification: • D • K • P • C • O • F • G • S
  12. 12. Carl Linnaeus •a.k.a. Father of Taxonomy •Linnaeus developed the two-word naming system…binomial nomenclature.
  13. 13. Binomial Nomenclature •Two-word naming system (scientific name) •Bi means 2/nomial means name •Written in Latin •1st word represents Genus • Written capitalized, underlined or Italicized •2nd word represents Species • Written lower Case, underlined or Italicized

All belong to the same Kingdom: Animalia Same phylum: Chordata Same class: Mammalia Same order: Carnivora Dog, wolf, fox all belong to the same family: Canidae Dog and wolf belong to same genus: Canis Dog and wolf are different species
  16. 16. Dogs of different “breeds” all belong to the same species Canis familiaris; therefore all can mate and produce fertile offspring.
