18-1 Order in Diversity

• Huge diversity of life
• Must be a way to classify them
• Taxonomy scientific classification of organisms
  with universally accepted names.
• What is the name of this animal?
• Cougar, panther, mountain lion, puma
• ? All are acceptable.

10
Scientific Names

• Puma concolor
• Binomial Nomenclature
• Developed by Carolus Linnaeus
• Two-part scientific name
• Names are Italicized
• First letter-first word capitalized
• Second word is lower-case
• Ursus maritimus
• (GENUS) species name

11

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
• STUDY for TEST.

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
• 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
• 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
