  3. Inv. 31: Classification

  4. Notes: Classification

  5. Video: History of Classification

  6. Taxonomy • taxonomy- classification of living things • Use DNA to classify life today • Called phylogeny

  7. Nomenclature • Nomenclature- naming structure • Linnaeus developed classification based on structural features • Organisms with similar features were in the same groups • Rules: • No reusing genus names for different groups • No reusing species names

  8. Why Scientific Names? Common Names: • Puma • Cougar • Mountain lion Scientific name: Puma concolor

  9. Why Scientific Names? Mule Deer/Black Tailed Odocoileushemionus White Tail/Eastern Odocoileusvirginianus

  10. Why Scientific Names? Common Names: • Killer Whale • Orca • Orca Whale • Blackfish Scientific Name: Orcinus orca (Linneaus, 1758)

  11. Nomenclature • Two-term, Latin naming system • Binomial (2 name) nomenclature: Homo sapiens • 1st name = genus; capitalize first letter • 2nd name = species; not capitalized • Both words italicized or underlined

  12. Classification Groups • 8 levels • As you move down, groups become more specific and more similar

  13. Classification Groups Mnemonic: Your Mnemonic: • Domain • Kingdom • Phylum (plural = Phyla) • Class • Order • Family • Genus (plural = Genera) • Species Dear King Philip Can Order Five Good Shoes

  14. Domains 1. Eubacteria- true bacteria 2. Archaea- primitive, unicellular organisms that live in extreme environments 3. Eukaryotes- everything else (plants, animals, fungi…) Eubacteria

  15. 2 Cell Types 1. Prokaryotes • Archaea& eubacteria • Unicellular • No membrane-bound organelles • No nucleus • Smaller cells

  16. 2 Cell Types 2. Eukaryotes • Fungi, plantae, animalia, protista • Multicellular • Many organelles • Nucleus • Larger cells

  17. Vertebrate Assignment
