What Do I Need to Know???
State Standards
Lingo…Basically, What You
are EXPECTED TO KNOW
at the end of this unit!
Each objective will be covered in class and you
are responsible for knowing this information
for the Evolution Test.
SB5: Students will evaluate the role of natural selection in the development of the theory of evolution.
SB5a. Trace the history of the theory.
1. Explain the difference between spontaneous generation and biogenesis. Include the experiments involved.
2. Define the endosymbiont theory. Include its evidence.
3. What today resembles the first organisms on Earth?
4. Who is Lamarck and what was his theory? Why was it incorrect?
5. Who is Darwin and what was his theory?
SB5b. Explain the history of life in terms of biodiversity, ancestry, and the
rates of evolution.
1. What combination of characteristics would lead to the greatest potential for evolutionary change?
o small population with many mutations
o small population with few mutations
o large population with many mutations
o large population with few mutations
2. What is the Hardy-Weinberg Principle?
3. List the 5 conditions needed for genetic equilibrium.
4. Define speciation.
5. Explain the difference between allopatric speciation and sympatric speciation.
6. What is a gene pool?
7. What is gene flow? Describe the types below
o Bottleneck Effect:
o Founder Effect:
o Emigration:
o Immigration:
8. What is adaptive radiation? What is an example that Darwin referred to?
9. How does convergent evolution lead to analogous structures? Give an example and explain.
10. If a mutation is introduced into a population, what factor would determine whether the frequency of that
allele (mutation) will increase?
11. What is coevolution? Give an example and explain. Good ex’s: http://en.wikipedia.org/wiki/Coevolution
SB5c. Explain how fossil and biochemical evidence support the theory.
1. What causes new traits to evolve?
2. What is camouflage and how does it benefit the survival of the species?
3. What are homologous structures? Give an example.
4. What are analogous structures? Give an example.
5. What are vestigial structures? Give an example.
6. Compare and contrast ancestral and derived traits.
7. How do fossils provide evidence for evolution?
8. What types of rocks are fossils formed in and why? Give 2 examples.
9. How does mimicry benefit the survival of a species and give an example?

SB5d. Relate natural selection to changes in organisms.
1. How does Hardy-Weinberg relate to natural selection and evolution?
2. What is an adaptation? Give an example of a physical and a behavioral adaptation.
3. What is fitness?
4. Explain the phrase “Natural selection is the mechanism for evolution”.
5. What does “Survival of the Fittest” mean? Include fitness and adaptation into your answer.
6. Describe the 3 types of natural selection and sketch the graph for each. (pg. 434)
Directional Selection
Stabilizing Selection
Disruptive Selection
7. What is Pre-zygotic isolation? Describe the 4 types.
o Temporal:
o Geographical:
o Ecological:
o Behavioral:
8. What is Post-zygotic isolation? How does this lead to hybrid sterility?
9. Explain how Kettlewell’s experiment with moths in sooty (dark) forests and non-sooty (light) forests
demonstrates natural selection and explain which of the 3 types it represents.
SB5e. Recognize the role of evolution to biological resistance (pesticide and
antibiotic resistance).
1. How do bacteria develop resistance to antibiotics?
2. How could antibiotic resistance become a problem for humans?
3. How do insects develop resistance to pesticides?
4. How could pesticide resistance become a problem for farmers?
