15. 18-2 Modern Evo Classification
Linnaeus grouped species visible similarities and differences.
Evolutionary classification based upon evo history.
Phylogeny – grouping of organisms through lines of evolutionary descent.
Descent with modification
may physically appear similar
very different morphologically
and physiologically.

16. Cladograms Derived characteristics appear in recent parts of lineage.
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

17. Shared Common Traits DNA and RNA
Genes  Human and yeast genes both code for MYOSIN
DNA Evidence  Very different looking organisms have similar mechanisms
American vulture closer to Stork than African vulture
Molecular clocks uses DNA comparisons to estimate time that two species have evolved independently.

18. Question of the DAY Apr 4
In phylogeny, what is the name given to a group of organisms and all of its common ancestors and descendants?
A. Cladogram
B. Clade
C. Food web
D. Energy pyramid

19. Question of the Day
A clade is a grouping that includes a common ancestor and all the descendants (living and extinct) of that ancestor.
Imagine clipping a single branch off the phylogeny — all of the organisms on that pruned branch make up a clade.

20. AGENDA April 4 Big Question: How are different organisms classified?
1. Finish Chapter 18
2. Study Guides
Chapter 17/18 Test on MONDAY April 7
3. Review and Homework

21. 18-3 Kingdoms and Domains Five Kingdoms  SIX Kingdoms
Eubacteria, Archaebacteria, Protista,
Fungi, Plantae, Animalia
THREE-Domain System
1. Eukarya
2. Bacteria
3. Archaea

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

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

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

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

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