5. LAUNCH

6. Evolution part 4 Modern theory of evolution and examples
Be able to explain what is different from Darwin’s theory.

7. Modern Theory of Evolution
Is a combination of Darwin’s Theory and DeVries

8. Natural Selection
Traits that have a high survival value are retained and passed on
Traits with a low survival value diminish in frequency
Changes in the environment may change the survival value of a trait

9. If a mutation helps a species survive, it will become more common
If a mutation helps a species survive, it will become more common. If a mutation is deadly, it will eventually disappear.

10. Examples Peppered Moths Microorganisms resistant to penicillin
Insects resistant to pesticides

11. Modern Examples of Evolution:
1. Peppered Moths
England, 1848
Moths rest on Lichen-covered tree barks.
There are more white moths in the population.

12. Evolution In Action!
Why is Sexual reproduction better for a species than Asexual reproduction?

13. The Peppered Moth: England 1848

14. INDUSTRIAL REVOLUTION

16. Evolution

17. Evolution

18. Try to describe how each illustration is an example of each evolutionary term.

19. Continue and then answer the questions below

21. Light colored and dark colored moths exist
Dark and Light colored moths reproduce to increase in population

22. Industry causes the moths to struggle for existence the dark colored moths are successful
Dark colored moths survive the change better then the light colored moths. No No
They were better camouflaged therefore better able to survive.

23. natural selection Genetic variation Mutations Sexual reproduction
adapt
Overproduction

24. fit reproduce Struggle for existence Competition offspring more
Strongest individuals

Evolution Notes Ms. Romer
2. Antibiotic-Resistant Bacteria

27. Antibiotic-Resistant Bacteria
Evolution Notes Ms. Romer
Antibiotic-Resistant Bacteria
What was the selective pressure?
Who applied it?
WE DID.

28. Antibiotic-Resistant Bacteria
Variety Exists

29. Antibiotic-Resistant Bacteria

30. Did the antibiotic mutate the bacteria’s DNA?
NO!
Variety Already Existed

31. Did bacteria become resistant because they needed to?
NO!

32. Did the bacteria get “used to” the antibiotic?
NO!

33. Variety Already Existed
WHY did one survive?
Variety Already Existed

34. Antibiotic-Resistant Bacteria
Evolution Notes Ms. Romer
Antibiotic-Resistant Bacteria

35. Would this have happened without antibiotics?
Evolution
Original Population
New Population
Would this have happened without antibiotics?

36. The bacteria that survived exposure to penicillin learned to avoid it.
Why does penecillin not work on bacteria anymore?
The bacteria that survived exposure to penicillin learned to avoid it.
During each generation, the bacteria modified their own DNA to increase their ability to resist penicillin and passed this ability on to their descendants.
Members of the original population of bacteria that were penicillin resistant survived and reproduced, creating a more resistant population.
The bacteria that caused the new outbreaks were from populations that had never been exposed to penicillin.

37. Do NOT take antibiotics unless absolutely necessary!
Antibiotics do NOT kill viruses.

38. BRAIN POP Antibiotic resistance

41. Regents review question: Antibiotic Resistance bacteria

42. Regents review question: Antibiotic Resistance
pesticides

43. What causes antibiotic resistance?
youtube
Mutations - selection: the bacteria resist (Animation 5 minutes.)

44. 3. DDT-Resistant Insects
DDT is an insecticide (bug-killer) that has been used to kill pests on crops.
At first, DDT killed most of the pests.
But soon, the majority of the pest population had a DDT-resistance gene.
Explain (in at least 3 steps) the events that led to this evolution of pests.

47. DDT also killed Falcons, Eagles, and Osprey by making the egg shells thinner.

48. A large population of house flies was sprayed with a newly developed, fast-acting insecticide. The appearance of some house flies that are resistant to this insecticide supports the concept that:
species traits tend to remain constant
pesticides cause mutations
variation exists within a species
the environment does not change

49. Practice problem

Pesticide Resistance

51. Evolution part 5 Rates of evolution
Be able to explain gradualism vs punctuated equillibrium and why 2 beliefs exist.

52. How fast does evolution occur?

53. SLOW Evolution: Horseshoe Crab
Evolution Notes Ms. Romer
SLOW Evolution: Horseshoe Crab
150 million- year old fossil

54. Rate of Evolution How Fast Will a Species Change?
Evolution Notes Ms. Romer
Rate of Evolution How Fast Will a Species Change?
Evolution will occur more quickly if:
Lots of VARIETY
High selective pressure (The environment changes.)
Lots of competition to survive and reproduce.

55. How fast is evolution when…
The Environment stays stable?
SLOW
Selective pressure is applied?
FAST
Conditions are harsh?
Lots of competition?

56. Time Frame for Evolution
Gradualism – evolution is slow, gradual and continuous

57. Time Frame for Evolution
Punctuated Equilibrium- species have long periods of stability interrupted by brief periods of change (mutations), during which new species may evolve

58. Common Ancestors
Organisms that exhibit similar structures, biochemistry, etc. have common ancestors
More similarities  Closer the evolutionary relationship
Illustrated by Phylogenetic Tree
“CLADOGRAM)

59. Phylogenetic Tree

60. Phylogenetic Tree

61. Extinction When all members of a species disappear from the earth.
The mortality (death) rate exceeds the birth rate.
Extinction usually occurs because of changes in the environment
If there is variation within a species, it is more likely that some will survive.

62. Failure of a species to adapt to a changing environment.
Extinction:
Failure of a species to adapt to a changing environment.

63. Natural Selection

64. Which statement describing a
cause of extinction
includes the other three?
Members of the extinct species were unable to compete for food.
Members of the extinct species were unable to conceal their presence by camouflage.
Members of the extinct species lacked adaptations essential for survival.
Members of the extinct species were too slow to escape from predators.

65. Which species are extinct? Who’s more closely related?
M and O or M and L and WHY??
P and L or P and G and WHY??
H and P or H and D and WHY??

66. Who is the common ancestor of A and E?
Who is the common ancestor of J and B?
Who is the common ancestor of A and B?
Who is extinct?

67. Which species was the first to become extinct?

68. Which statement could best be inferred from the information in this diagram?
Evolution does not involve gradual change.
Evolutionary changes can result in extinction.
Evolution begins with plants.
Evolution produces organisms that all fill the same niche.

69. Coevolution
Australian Rabbit
South American Rabbit

70. Fun Facts Possibly 10 billion species have ever existed.
Of all species that ever inhabited the Earth over 99% of them are now extinct.
The primary reason for these extinctions is environmental change or competition.
They did not have the mutation that would have enabled them to survive.

71. True or False? Organisms change their DNA to suit the environment.
Variety exists due to sexual reproduction.
Organisms can get used to a poison.
Organisms can learn how to be immune to a poison.
DNA mutates based on the needs of the species.
Populations that have a lot of variety will have a mutation to allow them to survive.

72. Bad Answer Choices For Evolution Questions
Change occurs according to the needs of an organism to survive.
An individual can evolve.
An antibiotic or insecticide can cause the mutation that resists it.
Bacteria “get used to” antibiotic.
Bacteria “learn” how to fight it.

73. Each point in the graphs represents a new species
Each point in the graphs represents a new species. Which graph best represents the concept of gradualism?                  

74. Evolution of the Species
Why is there such a variety of organisms on Earth?

75. Which species are extinct? Who’s more closely related?
M and O or M and L
P and L or P and G
H and P or H and D

76. Who is the common ancestor of A and E?
