- "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
- 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. If a population of algae eaters experiences predation pressure from pike-cichlids, which of the following would least likely be observed in the algae-eater population over the course of many generations?
- In evolutionary terms, the more closely related two different organisms are, the
- 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?
- a c. Female algae eaters may become larger, bearing broods composed of more, and larger, young.
- b a. genetic variation among individuals
- c c. more recently they shared a common ancestor.
- d e. A, B, and C
- e b. Lamarckism.

The biological explanation for this observation is most properly associated with the field of → c. more recently they shared a common ancestor.

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