Tree squirrels can have different fur colors.

Squirrels live in forests where foxes also live. Foxes hunt squirrels for food. Squirrels that have fur that is the same color as the trees are harder for the foxes to see and catch.

a)

You cannot tell how the environment changed. With each generation, more squirrels passed on the gene for black fur to their offspring.

b)

There were more black trees. Squirrels with black fur are more likely to survive, so the squirrels with gray fur changed to have black fur.

There were more black trees. With each generation, more squirrels with black fur survived long enough to pass on the gene for black fur to their offspring.
