Monarch butterflies have a chemical in them that makes them taste bad to birds. As a result, birds learn to avoid Monarchs and other butterfly species that look like them, such as the Viceroy butterfly. In an area that has Monarchs, Viceroys, and the dark colored Black Swallowtail, what is most likely to occur to the butterfly populations over time?

• The number of Monarch butterflies in the community will increase

• The number of Viceroy butterflies in the community will decrease

• The number of Black Swallowtail butterflies in the community will decrease

• The Black Swallowtail butterflies will leave the area to avoid competing for limited resources

Male seahorses can release as many as 2000 fully developed babies at once after he incubates the seahorse eggs for 9-45 days. How does this increase the fitness of the seahorse?

• The baby seahorses will migrate to new ocean waters and cause gene flow

• Having many offspring increases the chance of mutation events

• The baby seahorses will have to compete more for food in a larger population

• Having thousands of offspring increases the chance that some will survive to reproductive age and pass on their genes

The graph shows the survival rates of two species of field mice in a farmer's field over a period of 4 years. What conclusion can be drawn from this data?

• Field Mouse Y is more fit than Field Mouse X

• There are more Field Mouse Y mice than Field Mouse X mice in the field

• Field Mouse X mice have shorter life-spans than Field Mouse Y

• Field Mouse Y mice are more likely to have favorable mutations

In Africa, one pride (group) of lions moves into another pride's territory in search of prey. The two prides join together and mate with one another. What is the most likely consequence of this interbreeding?

• The lion offspring from the two prides interbreeding are more likely to have mutations

• The lion offspring from the two prides interbreeding will be favored by natural selection

• The interbreeding of the two prides will introduce more genetic variation

• The lion offspring from the two prides interbreeding will be more fit

The Burdock plant produces seeds called burrs which have lots of sharp hooks. These hooks catch in the fur and hair of passing animals and travel with them. What is the advantage of this seed disbursal strategy?

• There is an increased chance animals will eat the seeds.

• These seeds will travel long distances and be spread out so that they experience less competition for resources.

• These seeds will need less water than other seeds.

• The plants that grow from the burrs will have a longer life cycle.

The picture above shows the evolution of an early ancestor to modern sand dollars (a type of flattened sea urchin). Which is best supported by this fossil record?

• The organisms in the oldest rock layer were not very well suited to their environment. The shape of the organisms changed slowly over time, with each more fit species out-competing the one before it.

• The organisms in the oldest rock layer were well suited to their stable, unchanging environment. Very little change happened for many years. A rapid change in the environment caused these organisms to be less fit, and it became suddenly favorable to have markings and arms.

• The organisms in the oldest rock layer were well suited to their environment. They interbred with a new species of early sand dollars which led to populations of organisms with markings and arms.

• Humans introduced new species of early sand dollars which out-competed the original species present in the oldest layers of rock.

Males of two songbird species in the Caribbean islands use mating songs to attract the opposite sex for breeding. The songs, however, are so different that female songbirds will only recognize the song of their own species. Which of the following will NOT occur?

• Genetic drift of the two songbird species

• Mutations in the two songbird species

• Natural selection for adaptive traits in the two songbird species

• Gene flow between the two songbird species

Pictured above are drawings of amphibian, reptile, bird and mammal hearts. Which statement is best supported by this drawing?

• Amphibians, reptiles, birds, and mammals all share a common ancestor

• Amphibians, reptiles, birds, and mammals all live in similar environments

• Amphibians, reptiles, birds, and mammals all interbreed

• Amphibians, reptiles, birds, and mammals all have similar diets

Based on the geographic distribution of the species pictured, which statement is most likely correct?

• At one point in the past, a common ancestor of all four species existed. Migration of some of the ancestral population to new places exposed each migrating group to different selective pressures. This lead to evolution of the ancestral species into Giant Armadillos, Giant Pangolins, Giant Anteaters, and Spiny Anteaters.

• These 4 species do not share a common ancestor and each evolved independently to best suit their local environment.

• These four species evolved from a common ancestor in one location. Then, after evolving, each species migrated to new locations where they were better suited to the environment.

• The Giant Anteater and Spiny Anteater share a common ancestor, but are not related to the Giant Armadillo or Giant Pangolin.
