Who is the "King" of the bears?

[Polar]

@Majingilane,

I would also agree with your desire of the brown bear as king, only under section III, though. Note that adaptability falls under section III. Unlike many other carnivores such as machairodonts, felines, or other ursids, brown bears:

-Weren't as big, and thus didn't require much of the nutrients that larger carnivores needed (useful for hyper-competition, where prey famine starts to occur).

-Hibernated just like the black bear did, so it didn't have possible risk of starvation or injury like other carnivores during those months.

-Have a more intimidating, "bully-like" aggressive behavior which gave them more prey to steal off of.

But in terms of the ability to achieve maximum size (and higher average size), and to regularly kill prey (both large and small), the polar bear and Agriotherium takes the bait. Although, some large modern brown bears (and prehistoric ones) hunt/hunted deer and large bovines, they don't do it on a regular basis. Most were omnivorous or scavenged. Only the exceptionally large brown bears regularly took meat as their primary source of food. Reply
