Evolution of the human pelvis

Brain size has a strong effect on human hip bones. The shape of human hip bones results from a compromise between walking on two legs and giving birth to large-brained babies.Humans need narrow hips to walk on two legs, but they also need wide hips to have babies with big brains. This problem is known as the obstetrical dilemma.
