  4. In a hypothetical environment, fishes called pike-cichlids are visual predators of algae-eating fish, i.e., they locate their prey by sight.

5 True/False questions

  1. If the HMS Beagle had completely bypassed the Galapagos Islands, Darwin would have had a much poorer understanding ofb. the ability of populations to undergo modification as they adapt to a particular environment.


  2. Which of the following represents an idea Darwin took from the writings of Thomas Malthus?b. Populations tend to increase at a faster rate than their food supply.


  3. "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 ofb. Lamarckism.


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


  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?d. Well-adapted individuals leave more offspring, and thus contribute more to the gene pool, than poorly adapted individuals.
