Why do human beings walk on feet?

Human are the only strictly bipedal primates, and their body structure conforms to that posture. Walking upright on the rear appendages allows quadrupedal animals to use the forward appendages in a variety of fashions, and ultimately to use tools. The opposable thumb exists only on the upper appendages (arms) and not on the lower appendages, legs, so the feet are not as capable of manipulation. They do require a distinct set of joints and muscles to support and balance the body in a variety of motions.
