      kangaroos have a very clever and unique way of regaining spent energy in their legs. When they land, the energy is stored (like in a spring) in their legs and they effortlessly spring off again.

      Our ancestors most likely climbed trees and legs of this design wouldn’t work at all up there! so it was never an option for us.
