Question

Quizplus · Accepted Answer

The development of curvatures in the spine is necessary to balance the head and upper body on top of the hips when standing upright. The short, broad ilium provides a stable attachment point for the hip muscles, which are essential for maintaining balance while walking. Finally, the development of a short, inflexible big toe enables the foot to act as a rigid lever during the push-off phase of walking. All of these adaptations are found in the human skeleton and are necessary for erect bipedalism.
