Adaptive radiations can be a direct consequence of three of the following four factors. Select the factor that is NOT a direct consequence of adaptive radiation. Select one: a. Genetic drift b. Vacant ecological niches (niches are environment "space" where a particular organism has resources required to survive and reproduce) c. New evolutionary innovations d. Colonization of a new region that contains suitable habitat and few competitor species

The Galapagos archipelago consists of volcanic islands that formed within the last 5 million years. Darwin wrote of the finches on these islands, "...from an original paucity of birds in this archipelago, one species has been taken and modified for different ends." The Galapagos finches are an example of adaptive radiation driven by a. behavioural innovation. b. morphological innovation. c. ecological opportunity. d. physiological innovation.

Adaptive radiation is common following a period of mass extinction, probably because (a) the survivors of a mass extinction are remarkably well adapted to their environment (b) the unchanging environment following a mass extinction drives the evolutionary process (c) many adaptive zones are empty(d) many ecological niches are filled (e) the environment induces changes in the timing of development for many species
