15. DNA & The Genetic Code

18. Fossil Record
Strata & Superposition
Relative Age vs. Absolute Age

19. Fossil Record
Per the theory - You would expect older rock to contain mostly organisms that are less complex and less like current (living) organisms

21. Transitional Species in the Fossil Record

22. Transitional Species

23. Biogeography
The study of the location of living organisms

24. Biogeography

25. Populations Adapt – Individuals Can’t (They acclimatize)
Fitness = ability to make a hereditary contribution to the next generation
Populations Adapt – Individuals Can’t (They acclimatize)

26. Explaining things… (some examples of natural selection at work)

27. Convergent Evolution

31. Analogous Structures
Similar purpose – different origin

32. Divergent Evolution

41. Artificial Selection

43. Sexual Selection

44. Relaxed Selection – Backward Evolution?

45. Altruism

46. Seeing Evolution – Looking at Populations

47. Q: How do we see evolution?
A: In populations Natural Selection acts on populations by changing the composition of the gene pool.

48. Gene Pool

50. Population Genetics
Bell Curve – Ding! You’re most likely…looking at average!

51. Hardy-Weinberg Equilibrium
No evolution if:
1. No net mutation occurs
2. Individuals do not leave or enter population.
3. The population is large
4. Individuals mate randomly
5. Selection does not occur

52. Non-random Mating
Sexual Selection

53. Gene Flow
Mutation
Immigration (In)
Emigration (Exit)

54. Genetic Drift – small population problems
or founder effect
