EVOLUTION II PREVIEW
CHAPTER 8
1. Define or provide an example for:
Genotype
Phenotype
CHAPTER 15
2. Define or provide an example for:
Fossils
Superposition
3. According to section 15.2 (pages 303-307) what are the four major categories of evolutionary evidence
(HINT: Look at the all capitalized bold-faced subheadings in blue).
4. Define or provide an example for:
Divergent evolution
Convergent evolution
Homologous structures
Analogous structures
Vestigial structures
CHAPTER 16
5. Define or provide an example for:
Gene pool
Bell Curve
6. Sketch the bell curve in figure 16.1 on page 317.
7. Go to figure 16.8 on page 325. How does each of the type of selection alter the look of the bell curve you
drew in #6? You can describe it or sketch the change.
Stabilizing selection
Disruptive selection
Directional selection
8. Go to page 320 and read the short section “Hardy-Weinberg Genetic Equilibrium”. If a population is in
equilibrium then the population is said to be (evolving/not evolving). Circle one.
9. Five factors can push a population out of equilibrium and cause the population to change. What are those
five factors? Look through section 16.2, “Disruption of Genetic Equilibrium”, at the all capitalized boldfaced subheadings in blue.
