• Survival of the Smartest

• Natural Selection

A fox with thicker fur than average would have a survival advantage over other foxes if:

• There is more competition for food in the fox population.

• The air temperature significantly decreases in winter.

• A drought occurs, limiting the amount of water available.

• A new disease appears that infects the foxes.

Animals may fight, make threatening sounds,and act aggressively toward members of the same species. These behaviors usually occur as the result of:

• Adaptation

• Evolution

• Competition

• Variation

The finches on the Galapagos island were similar in form except for variations of their beaks. Darwin observed that these variations were useful for:

• Attracting a mate.

• Gathering food.

• Defending territory.

• Building nests.

• Overdeveloped

• Overpopulated

• Extinct

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
