A brown mouse lives in the mountains. It blends with the soil. Predators cannot see it. Some of its babies are born with grey fur. Predators easily see the grey mice and eat them.
Then, a volcano erupts and changes the environment. The ground is now a black or gray color.
After natural selection, which mouse will there be more of? Why?
A mouse with grey fur because it would blend in better to the environment
A mouse with brown fur because it would blend in better to the environment

An anole with 18 scales making it slower to climb.
An anole with 24 scales making it faster to climb.
