Unit Objective

  • Explain how theories of gradualism and uniformitarianism influenced Darwin’s ideas about evolution.
  • Describe Lamarck’s explanation of how adaptations evolve and compare it to Darwin’s.
  • Explain the tenets of Darwin’s theory of evolution by natural selection, using Darwin’s and modern examples.
  • Explain evolution by natural selection through a series of simulations and labs (butterflies and strawfish).
  • Use the Hardy-Weinberg theorem to calculate allele, genotype, and phenotype frequencies in a population at equilibrium, and describe and explain the conditions that violate this equilibrium through a lab. Describe the usefulness and limitations of the HW model.
  • Explain how genetic drift, gene flow, mutation, nonrandom mating, and natural selection lead to evolution within a species as well as speciation. Explain and give examples of the three types of selection.
  • Explain the causes of genetic variation – mutation, recombination (delayed until genetics units), sexual reproduction – within a population and the prevalence of sexual reproduction as a way of providing variation through a reading, video, discussion, and simulation. Explain how sexual selection contributes to evolution.
  • Define, compare/contrast, and give examples of adaptive radiation, convergent and divergent evolution; allopatric, sympatric and parapatric speciation; gradualism and punctuated equilibrium.
  • Describe how the following gives evidence of evolution: embryology, fossils, homology, vestigial organs, and biochemistry.
  • Define the biological species concept and describe the limitations of the concept.
  • Distinguish between prezygotic and postzygotic isolation mechanisms.
