Aside from offering better balance, the S-shaped spine is also good for absorbing the mechanical shock that comes from walking. Other advantages that pushed the evolution of bipedalism in the savanna, according to this theory, were that the upright posture made it easier to acquire food in trees that would have otherwise been out of reach, and walking on two legs was more energy efficient. b.
