3 Chapter18

  1. 1. Chapter 18: Classification All slides done by Travis(Vanilla Bear) Switzer and Andy Chen
  2. 2. Classification <ul><li>We Classify organisms for many reasons, mostly to organize the wide diversity of life on our planet. </li></ul>By Travis Switzer and Andy Chen
  3. 3. Levels of Classification Kingdom Phylum Class Order Family Genus Species By Travis Switzer and Andy Chen
  4. 4. Scientific names <ul><li>Binomial Nomenclature: The process of assigning two names to every organism. These are the names of the Genus, followed by the Species. </li></ul><ul><li>These names are internationally recognized by all scientists. As to avoid confusion between organisms. </li></ul>By Travis Switzer and Andy Chen
  5. 5. Evolutionary Classification <ul><li>For a long time, classification was done by comparing animals traits. This led to many species being grouped together with little evolutionary history. It is now done with cladograms by comparing evolutionary relationships. </li></ul>By Travis Switzer and Andy Chen
  6. 6. Molecular Clocks <ul><li>As organisms evolve, harmless mutations build up in the DNA, these can be compared to view evolutionary history. </li></ul>By Travis Switzer and Andy Chen
  7. 7. Kingdoms and Domains All life is classified into three domains and five kingdoms, and then further broken down through the other levels of classification. By Travis Switzer and Andy Chen
  8. 8. Domain Eukarya <ul><li>Contains the kingdoms animalia, plantae, fungi, and protista. Characterized by organisms having eukaryotic cells. </li></ul>By Travis Switzer and Andy Chen
  9. 9. Domain Bacteria <ul><li>Contains the kingdom eubacteria, characterized by having prokaryotic cells that have peptidoglycan in their cell walls. </li></ul>By Travis Switzer and Andy Chen
  10. 10. Domain Archaea <ul><li>Contains the kingdom archaebacteria, characterized by having prokaryotic cells without peptidoglycan in their cell walls. Generally, archaebacteria are extremophiles. </li></ul>By Travis Switzer and Andy Chen
