  2. Eons
    • Haden
    • Archean
    • Protozoic
    • Phanerozoic 

    bolded is precambrian
  3. 65 mil years ago
    dinosaurs go bye bye
  4. Permian/triasic
    when dinosaurs and mammals appear
  5. first prokaryote
    archean eon
  6. first eukaryotic
    proterzoic

    • dino go extinct
    • first primate in genus homo

  9. hardy weinberg equation
    • p + q = 1
    • p^2 + 2pq + q^2 = 1

    • p is dominant (from gene pool)
    • q is recessive
    • p^2 is frequency of dominant GENOTYPE 
    • 2pq F of heterozygous genotype 
    • q^2 is F of homozygous recessive genotype
  10. equilibrium can only occur
    • the population is very large
    • mating is random
    • no selection
    • no net change in pool due to mutation 
    • no migration in or out
  11. genetic drift
    smaller population affected more and can get fixed allele faster than larger population
  12. 5 mass extinctions
    • Ordovician
    • Devonian
    • Permian ** largest 
    • Triassic
    • Cretaceous

    • size - male has a larger brain case size

    • neanderthal skull larger than human
  19. male vs female chimp

  20. taxonomy hierarchy
    • domain 
    • super group (eukaryotes)
    • kingdom 
    • phyla
    • order
    • family
    • genus
    • species
  21. protozoic eon 
    mult cell eukaryotes 
  22. phanerzoic eon
    multi cell rule the world 
  23. cambrian
    major phila come to play 
  24. ordovian 
    • first land plants
    • climate change
  25. sulurian
    new fish glaciers are gone
  26. devonian
