Chapter 21, Problem 3A

Convergent evolution is often seen among species on different islands because

a. island populations are usually smaller and more affected by genetic drift.

b. disruptive selection occurs commonly on islands.

c. island species are usually most closely related to species in similar habitats elsewhere.

d. when islands are first colonized, many ecological resources are unused, allowing descendants of a colonizing species to diversify and adapt to many different parts of the environment.

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.
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.
In nature, when a lone male lion encounters a pride (a group of lions with a male leader), the two males will often fight to become head of the pride. It has been documented that if the foreign lion wins the battle, he will usually kill the offspring of the weaker lion’s pride. This natural selection process best describes; Select one: a. Fitness within species  b. Bottleneck effect  c. Macroevolution  d. Microevolution  e. Speciation
