    • Chimps and goril­las get about by knuck­le-walk­ing. They curl back their fin­gers and bear the weight of their upper bod­ies on their knuck­les, which per­mits them a four-legged scoot on the ground while retain­ing long, grasp­ing fin­gers for swing­ing Tarzan-like among the branch­es. A nice com­pro­mise between life in the trees and life on the ground.
