Bipedalism is a hallmark of hominins. Hominins are the only animal group to walk on two legs habitually. However, it is not as simple as deciding to become bipedal. Our skeletal anatomy has adapted to facilitate bipedalism. If you were to try walking on all fours, you would likely find it uncomfortable due in part to the shape and alignment of your bones. Describe how skeletal anatomy has adapted in hominins to promote bipedalism.
