• Evolution

• Natural Selection

• Extinction

• Artifical 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

How does adaptation benefit a species?

• It allows a species to become less visible to predators.

• It enables a species to better survive and reproduce in its environment.

• It ensures that all members of a species look exactly the same.

• It decreases the genetic diversity within a species.

Individuals in a population that have the traits needed to survive in the environment get to survive and reproduce. Their offspring inherit those traits. Over time, a greater percentage of the population will have those successful traits.

• Natural selection

• Selective breeding

• Artificial selection

• Mutations
