Ch. 22 Descent with Modification: A Darwinian View of Life
Describe Carolus Linnaeus’ contributions to Darwin’s theory of evolution.
- Explain how Cuvier and his followers used the concept of catastrophism to oppose evolution
- Explain how the principle of gradualism of Charles Lyell’s theory of uniformitarianism influenced Darwin’s ideas about evolution.
- Describe Jean Lamarck’s model of how adaptations evolve.
- Describe how Darwin used his observations from the voyage HMS Beagle to formulate his theory of evolution.
- Explain what Darwin meant by the principle of common descent and "descent with modification."
- Explain why variation was so important to Darwin’s theory.
- Distinguish between artificial selection and natural selection
- Explain why populations is the smallest unit that can evolve.
- Describe the lines of evidence that Darwin used to support the principle of common descent
Ch. 23 The Evolution of Populations
- Write the general Hardy-Weinberg equation and use it to calculate allele and genotype frequencies.
- List the conditions a population must meet in order to maintain Hardy-Weinberg equilibrium.
- Explain how genetic drift, gene flow, mutation, nonrandom mating, and natural selection can cause microevolution.
- Distinguish how inbreeding and assortive mating affect a population’s allele frequencies and genotype frequencies.
- Describe the technique of electrophoresis and explain how it has been used to measure genetic variation within and between populations.
- List some factors that can produce geographical variation among closely related populations.
- Describe what selection acts on and what factors contribute to the overall fitness of a genotype
- Distinguish among stabilizing selection, directional selection, and diversifying selection.
Ch. 24 The Origin of Species
- Distinguish between anagenesis and cladogenesis
- Explain how gene flow between closely related species can be prevented
- Distinguish between prezygotic and postzygotic isolating mechanisms
- Describe eight intrinsic isolating mechanisms and give an example of each
- Explain how hybrid breakdown maintains separate species even if gene flow occurs
- Distinguish among allopatric and sympatric and parapatric distributions
- Explain the allopatric speciation model and describe the role of intraspecific variation and geographical isolation
- Distinguish between autopolyploidy and allopolyploidy
- List some points of agreements and disagreements between the two schools of though about the tempo of speciation (gradualism vs. punctuated equilibrium)
