What changes have occurred to the person as a result of bipedal locomotion?

Considering the remains of ancient human ancestors, you can clearly trace changes in the skeleton. In connection with upright posture, changes began to appear in the structure of the musculoskeletal system. First of all, the ridge received four bends, which help to reduce the load on the body when walking and doing work. The length of the lower and upper limbs also changed. The rib cage has shrunk and narrowed. The same goes for the pelvic bone, which has shrunk. These are the main changes that are directly related to a person’s upright posture.
