The evolution of human bipedalism approximately four million years ago [1] has led to morphological alterations to the human skeleton including changes to the arrangement and size of the bones of the foot, hip size and shape, knee size, leg length, and the shape and orientation of the vertebral column.The evolutionary factors that produced these changes have been the subject of several theories. The vertebral column of other mammals except man has no curves.The vertebral column of apes has 1curve,while vertebral column of man has 4 curves.Due to this number of curves,man can stand erect and walk on 2 limbs.Other animal can't stand erect and walks on four limbs.And apes can stand semi erect and can walk on hindlimbs with support of knuckles of forelimbs.
