REVIEW -- Evolution by Natural Selection

Why is the mouse population changing over time?

• The light mice can reproduce more successfully than the dark mice

• The hawks eat more dark mice than light mice because the dark mice taste better

• The hawks eat more light mice than dark mice because they can see the light mice more easily

• The hawks eat more dark mice than light mice because they can see the dark mice more easily

Which of the following is a key component of natural selection?

• There is no competition for resources among organisms.

What can lead to the extinction of a species?

• An increase in the species' population.

• All individuals have similar traits (not enough genetic variation in the population).

• The development of good mutations.

• An increase in the species' habitat size.
