10. 18-2 Modern Evo Classification Evolutionary classification based upon evo history. Evolutionary classification based upon evo history. –Similar traits and appearances Phylogeny – grouping of organisms through lines of evolutionary descent. Phylogeny – grouping of organisms through lines of evolutionary descent. –Descent with modification

11. Cladograms appear in recent parts of lineage. Derived characteristics appear in recent parts of lineage. Used to construct Used to construct cladograms. – –Show evolutionary relationships Mini-LAB Page 453 Draw a cladogram Hint: Begin with a trait that only one organism is missing

12. Cladograms Arrange the following organisms into a cladogram. Arrange the following organisms into a cladogram. Lizard, Hamster, Salamander, Chimpanzee, Salmon Lizard, Hamster, Salamander, Chimpanzee, Salmon

14. 18-3 Kingdoms and Domains Five Kingdoms  SIX Kingdoms Five Kingdoms  SIX Kingdoms Eubacteria, Archaeabacteria, Protista, Eubacteria, Archaeabacteria, Protista, Fungi, Plantae, Animalia Fungi, Plantae, Animalia THREE-Domain System THREE-Domain System 1. Eukarya 1. Eukarya 2. Bacteria 2. Bacteria 3. Archaea 3. Archaea

15. Three Domains 1. BACTERIA 1. BACTERIA – –Unicellular and prokaryotic – –Cell walls contain peptidoglycan – –Very diverse survival mechanisms 2. ARCHAEA 2. ARCHAEA – –Unicellular and prokaryotic bacteria – –Extreme environments, most are anaerobic – –Unique lipids in cell walls 3. EUKARYA 3. EUKARYA –Eukaryotic –Kingdom Protista, Fungi, Plantae, and Animalia

16. Domain Eukarya PROTISTA PROTISTA Eukaryotic Not classified as animals, plants, or fungi – –characteristics of all three displayed Members have greatest variety Most unicellular Photosynthetic or Heterotrophic

17. Domain Eukarya FUNGI FUNGI Heterotrophs Heterotrophs –Feed on dead/decaying matter –Secrete digestive enzymes –Absorb smaller food molecules Multicellular – Mushrooms Multicellular – Mushrooms Unicellular - Yeast Unicellular - Yeast

18. Domain Eukarya PLANTAE PLANTAE Multicellular Multicellular Photosynthetic Photosynthetic Nonmotile Nonmotile Cell walls contain cellulose Cell walls contain cellulose Cone-bearing and Flowering Cone-bearing and Flowering Mosses and ferns Mosses and ferns

19. Domain Eukarya ANIMALIA ANIMALIA Multicellular Multicellular Heterotrophic Heterotrophic No cell walls No cell walls Have motility Have motility
