  1. 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?
  2. Catastrophism, meaning the regular occurrence of geological or meteorological disturbances (catastrophes), was Cuvier's attempt to explain the existence of

  1. a a. Characteristics acquired during an organism's life are generally not passed on through genes.
  2. b b. the fossil record.
  3. c c. Female algae eaters may become larger, bearing broods composed of more, and larger, young.
  4. d d. a mechanism for evolution that was supported by evidence.

  5. 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.
