<h2>Region between 2 and 3</h2>

Explanation:

Answer:

Black fur is more fit to survive in the environment than other colors of fur.

There may be black terrain that allows them to blend into the environment and ovoid predators, or maybe it keeps them warmer if it is located in a cold region, thereby reducing the amount of resources they need to spend to stay warm.
