  1. "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
  2. 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?
  3. In evolutionary terms, the more closely related two different organisms are, the
  4. A biologist studied a population of squirrels for 15 years. During that time, the population was never fewer than 30 squirrels and never more than 45. Her data showed that over half of the squirrels born did not survive to reproduce, because of competition for food and predation. In a single generation, 90% of the squirrels that were born lived to reproduce, and the population increased to 80. What inferences might you make about this population?
  5. 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?
  1. a e. A, B, and C
  2. b c. more recently they shared a common ancestor.
  3. c b. Lamarckism.
  4. d 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.
  5. e a. Characteristics acquired during an organism's life are generally not passed on through genes.

  1. e. The interaction of organisms with their environment is important in the evolutionary process.
  2. d. a mechanism for evolution that was supported by evidence.
  3. a. 2, 4, 1, 3
  4. e. individuals must adapt to their environment.
  5. b. Populations tend to increase at a faster rate than their food supply.

5 True/False questions

  1. 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 ofc. more recently they shared a common ancestor.

          

  2. Which of the following events, as described here, is most in agreement with the idea of catastrophism?d. the demise of the dinosaurs, and various other groups, by the impact of a large extraterrestrial body with Earth

          

  3. To observe natural selection's effects on a population, what must be true?e. individuals must adapt to their environment.

          

  4. Darwin had initially expected the living plants of temperate South America to resemble those of temperate Europe, but he was surprised to find that they more closely resembled the plants of tropical South America. The biological explanation for this observation is most properly associated with the field ofd. a mechanism for evolution that was supported by evidence.

          

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