Question 3

Some finches on the Galápagos Islands eat insects, an unusual food for finches to eat. These finches

Accepted Answer

A)  evolved from a lineage of birds other than finches that ate insects.
B)  learned their habits from local birds.
C)  switched to insects because they tasted better than their usual food.
D)  fill roles that birds other than finches would fill in other places.

Question 4

A fisherman catches one trout from each of two ponds. Pond A contains 100 trout and pond B contains 1,000 trout. Which population is more affected by the fisherman?

Accepted Answer

A)  Pond A; the fisherman has a greater likelihood of completely removing alleles from the gene pool by taking a fish from the smaller population.
B)  Pond A; fewer fish are able to move into a small pond and find mates.
C)  Pond B; the fisherman is more likely to catch a fish that is undergoing evolution in a bigger population.
D)  Pond B; the process of evolution occurs more slowly in large populations and removing a fish speeds up the process.

Question 5

In the following figure, the flying bird moves permanently into the population shown on land. As a result, the allele frequency of A in the population changes from

Accepted Answer

A)  1 to 0.75.
B)  0 to 0.25.
C)  0 to 0.75.
D)  1 to 0.25.

Question 9

Gene flow between two populations

B)  genetic bottleneck
C)  founder effect
D)  gene flow
E)  natural selection

Question 11

Compared to a large mainland population, genetic drift in a small island population is

Accepted Answer

A)  less important because there is less variation with which to work.
B)  less important because only a few individuals do all the breeding.
C)  more important because of a smaller gene pool.
D)  more important because of the absence of competition.

Question 12

Which of the following is NOT likely to be a cause of rapid evolution in a population?

Accepted Answer

A)  a changing environment
B)  an organism that exhibits a rapid rate of mutation
C)  an organism that reproduces very slowly
D)  the immigration of individuals carrying a new allele that significantly increases reproductive success

Question 13

Two populations of mice exist: one lives in an area with light rocks and the other lives in an area of dark rocks. A dark mouse from the population living on dark rocks migrates to the area of light rocks and breeds with mice there. Will this alter the allele frequency in the population? Discuss both changes that may or may not be seen in the next generation and in following generations.

Accepted Answer

The dark colored mouse will add dark all...

Question 16

Convergent evolution occurs when natural selection causes distantly related organisms to

Accepted Answer

A)  evolve into the same species despite the fact that they are members of separate populations.
B)  merge into one continuous population because of reversals in continental drift.
C)  evolve both analogous and homologous characteristics.
D)  evolve similar structures in response to similar environmental challenges.

Question 17

Match each example to one of the processes below.
-An area consists of dark and light rocks. Mouse populations that live on the dark rocks tend to be darkly colored; mouse populations that live on the light rocks tend to be lightly colored.

Accepted Answer

A)  genetic drift
B)  genetic bottleneck
