Question

The two bears above live in very specific places. The black bear here is much more widespread and has been around longer than the other two types. Explain how this black bear could have changed or evolved over time leading to the other two bears.

Answer 1

Explanation:

Black bears primarily hibernate to conserve energy during winter's food shortages. To prepare for hibernation, they gorge on food in the fall. This process of eating large amounts of food, called hyperphagia, builds their reserves of brown and white fat.
