• species

• lifespan

• adapted

• mutation

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 dark mice than light mice because they can see the dark mice more easily
