- 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?
- Which of the following events, as described here, is most in agreement with the idea of catastrophism?
- To observe natural selection's effects on a population, what must be true?
- "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
- 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
- a d. the demise of the dinosaurs, and various other groups, by the impact of a large extraterrestrial body with Earth
- 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.
- c b. Lamarckism.

5 True/False questions
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.
Which of the following must exist in a population before natural selection can act upon that population? → e. individuals must adapt to their environment.
Catastrophism, meaning the regular occurrence of geological or meteorological disturbances (catastrophes), was Cuvier's attempt to explain the existence of → b. the fossil record.
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.
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.
