identify the features that are associated with bipedalism as seen in humans.
1. short ilium - The short ilium of the pelvis is important in providing stability for bipedal motion.
2. s-shaped curve of spine - The hominin spine is curved to achieve balance in an upright position.
3. foramen magnum posterior to the skull - While in apes the foramen magnum is posterior to the skull, in humans it is at the bottom of the skull.
4. nonhoning canine - While the nonhoning canine is a feature of hominins, it is not related to bipedalism.
