  1. During drought years on the Galapagos, small, easily eaten seeds become rare leaving only large, hard-cased seeds that only birds with large beaks can eat. If a drought persists for several years, then what should one expect to result from natural selection?
  2. Which of the following events, as described here, is most in agreement with the idea of catastrophism?
  3. To observe natural selection's effects on a population, what must be true?
  4. "Improving the intelligence of an adult through education will result in that adult's descendants being born with a greater native intelligence." This statement is an example of
  5. In the mid-1900s, the Soviet geneticist Lysenko exposed winter wheat plants to ever-colder temperatures, collected their seeds, and then exposed the seedlings to ever-colder temperatures. He repeated his attempts over the course of decades in an attempt to evolve cold-tolerant winter wheat. Lysenko's attempts in this regard were most in agreement with the ideas of
  1. a d. the demise of the dinosaurs, and various other groups, by the impact of a large extraterrestrial body with Earth
  2. b d. More small-beaked birds dying than the larger-beaked birds. The offspring produced in subsequent generations have a higher percentage of birds with large beaks.
  3. c b. Lamarckism.
  4. d c. Lamarck.
  5. e e. A and B only

  1. d. a mechanism for evolution that was supported by evidence.

  4. e. individuals must adapt to their environment.
  5. b. the ability of populations to undergo modification as they adapt to a particular environment.

5 True/False questions

  1. Both Darwin's and Lamarck's ideas regarding evolution suggest which of the following?e. The interaction of organisms with their environment is important in the evolutionary process.


  2. Which of the following must exist in a population before natural selection can act upon that population?e. individuals must adapt to their environment.


  3. Catastrophism, meaning the regular occurrence of geological or meteorological disturbances (catastrophes), was Cuvier's attempt to explain the existence ofb. the fossil record.


  4. During a study session about evolution, one of your fellow students remarks, "The giraffe stretched its neck while reaching for higher leaves; its offspring inherited longer necks as a result." Which statement would you use to correct this student's misconception?a. Characteristics acquired during an organism's life are generally not passed on through genes.


  5. Which statement about natural selection is most correct?d. Well-adapted individuals leave more offspring, and thus contribute more to the gene pool, than poorly adapted individuals.
