- Natural selection is based on all of the following except
- Both Darwin's and Lamarck's ideas regarding evolution suggest which of the following?
- Which of the following must exist in a population before natural selection can act upon that population?
- In a hypothetical environment, fishes called pike-cichlids are visual predators of algae-eating fish, i.e., they locate their prey by sight.

- 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 c. Female algae eaters may become larger, bearing broods composed of more, and larger, young.
- b e. individuals must adapt to their environment.
- c a. Characteristics acquired during an organism's life are generally not passed on through genes.
- d e. The interaction of organisms with their environment is important in the evolutionary process.
- e a. genetic variation among individuals

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