Ok, maybe bears don't really walk, but why is it that they can sort of stand longer than other mammals? What in their bone structure or something helps them to do that?

The mechanics of the pelvis and the thigh joints have a lot to do with it. Our skull and neck joint has a lot to do with it.
No one knows exactly why we walk on two legs. the best guesses have to do with better view to detect predators.
Oh by the way, bears don't usually walk on two legs. they can, for a short time. Just like dogs and elephants in the circus. Many mammals can stand on two legs but not for a long time.

animals can walk on two leg also. What makes a human different (and better) than the rest that can walk on two legs is the ability stand on two legs for a very long time. The human foot is also a unique design, a arch that aides walking on two legs for a very very long time (no arch is called "flat feet" and the army won,t take you). Only humans can stand there for a long time by locking there knees (no animal can lock their knees).
Walking on two legs became a need as the disappearing forest led to wide areas of grassland. The ability to see over the grass was a lifesaver. There are many mammals that can stand or walk on two legs - bears, mice, rats, gophers, raccoons, squirrels, dogs, cats, Hares, monkeys, and many more

Actually Bears are not primarily Bi-pedal, and there are other mammals that are capable of walking Bi-Pedal such as Sea Otters, Gorillas, Kangaroos and Lemurs.

Kangaroos are bipedal. Chimpanzees and gorillas can walk on two legs and lowland gorillas do so for considerable lengths of time in the swamps of the Congo.

These animals are Bi legged( and for the bear quad legged) meaning they can stand on two legs.

actually any mammal can adapt to walking on two legs if necessary

Because they have an extra 2 legs and might as well get their money's worth ;-)

bears cannot remain mobile on two legs. only for a limited period of time. you are wrong.
