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.
Gene flow occurs
a. when individuals within a population interbreed.
b. as a result of genetic drift.
c. as a result of mutations in one population but not in another.
d. when an individual migrates between two otherwise isolated populations of a species.
A small number of animals moves away from a large ancestral population on the continental mainland and colonizes an island. Which of the following is likely to occur?
A. Genetic diversity will decrease on the mainland, because of a population bottleneck.
B. Alleles that were more rare on the mainland are likely to become more common on the island, because of the founder effect.
C. Genetic diversity will be lower on the island than the mainland, because of the founder effect.
D. Mutations rates will increase on the island, in response to selection pressures in the new environment.
