A population of fox inhabits a local forested area. Heavy rains and mudslides cause a river to change course, separating a population of Fox into two and destroying the forest on one side of the river. One group of fox still lives in its native habitat, but the other group now lives in the unshaded meadowlands. Which of the following statements is an adaptation the Meadowland foxes may acquire for thermoregulation?

A.) The fox group living in the forest will quadruple in size.

B.) The fox group living in the meadowlands will have a lighter fur coat.

C.) The fox group living in the meadowlands will migrate to the forest.

D.) The two fox groups will still be identical.
