Examine the illustration carefully.

Which is the BEST prediction of what might happen to the mice population over time?

• The colors of the mice will have little to no effect on the mice population.

• The darker-colored mice will be selected out of the population.

• The lighter-colored mice will be selected out of the population.

• The lighter-colored mice will become darker-colored.

Which of the following best describes a disadvantage of artificial selection?

• allows us to select traits for specific purposes (like guard dogs)

• allows us to produce much more food per plant

• it can lead to less diversity in a species over time

• it can create new varieties that wouldn't have otherwise existed

Change over time

• Natural Selection

• Evolution

• Selective Breeding

• Homeostasis

The graph shows how a finch population changed during the past 50 years. What can you infer based on the graph?

• Thin-beaked finches prey on wide-beaked finches.

• Wide-beaked finches are better suited for life in an ocean environment.

• Thin-beaked finches are better suited to the environment in Burke Lake.

• Wide-beaked finches are better suited to the environment in Burke Lake.

Natural selection can be best described as:

• The process by which species adapt to human needs

• A method of breeding for specific traits

• The process by which individuals with favorable traits survive and reproduce

• A random process without any direction or goal
