The consistent erect walking on two feet, or bipedalism, is the key feature that distinguishes hominins from other primates. While other primates may occasionally walk upright, hominins have adapted to bipedalism as their primary mode of locomotion. This adaptation has led to changes in the structure of their skeletal system, including the shape of their pelvis, spine, and leg bones.
