Test Review: Evolution
Chapter 22: Darwin
1. Describe Jean Baptiste Lamarck's theory of evolution.
2. Explain what Darwin meant by "descent with modification."
3. Explain what evidence convinced Darwin that species change over
time.
4. Describe the three inferences Darwin made from his observations that
led him to propose natural selection as a mechanism for evolutionary
change.
5. Using some contemporary examples, explain how natural selection
results in evolutionary change.
6. Explain how homologous structures support Darwin's theory of natural
selection.
7. Explain how biogeography and the fossil record support the evolution.
8. Explain how comparative anatomy, embryology, and molecular biology
supports Darwin’s theory.
Ch. 23 Population Genetics
1. Explain why it is incorrect to say that individual organisms evolve.
2. Define a population; define a species.
3. State the Hardy-Weinberg theorem.
4. Write the general Hardy-Weinberg equation and use it to calculate
allele and genotype frequencies.
5. List the conditions a population must meet to maintain HardyWeinberg equilibrium.
6. Define microevolution.
7. Explain how genetic drift, gene flow, mutation, nonrandom mating,
and natural selection can cause microevolution.
8. Explain the role of population size in genetic drift.
9. Distinguish between the bottleneck effect and the founder effect.
10.Distinguish among stabilizing selection, directional selection, and
diversifying selection.
11.Define sexual dimorphism and explain how it can influence
evolutionary change. (Sexual selection)
Ch. 24 Origin of Species.
1. Distinguish between prezygotic and postzygotic reproductive barriers.
2. Describe five prezygotic isolating mechanisms and give an example of
each.
3. Explain why many hybrids are sterile.
4. Explain how hybrid breakdown maintains separate species even if gene
flow occurs.
5. Distinguish between allopatric and sympatric speciation.
6. What causes the reproductive isolation in sympatric speciation?
7. Distinguish between gradualism and punctuated equilibrium.
Ch 25: Tracing Phylogeny
1. Explain how a cladogram or phylogentic tree is constructed.
2. Distinguish between homologous and analogous structures.
3. Make and or interpret a cladogram given characteristics or molecular
data for groups of organisms.
Ch 26: Origin of Life
1. Describe the theory of Chemical Evolution: 4 stages of hypothesis
2. List the 3 Domains of life and describe similarities and differences
