Why do we stand on two legs?

Scientists claim that walking on two legs was one of the keys to humans’ development from ancient ape-like ancestors. Walking on two legs saved energy and allowed the arms to be used for activities like hunting, crafting simple tools and interacting with objects.

As a group, the humans used 75 percent less energy walking upright than the chimps used walking on all fours. Essentially, walking upright seemed to be beneficial because it saved energy.

Why did humans evolve to stand?
