Lectures jan 8 feb 26 (inclusive: multiple choice, fill-in-the-blank, short answer. Knowledge of bipedal anatomy can help us determine where/when it developed. Hip-bones extend out and to the side and are more rounded whereas great ape hip bones are thinner, more angular, and extend upwards. Allows for difference in the angle in which weight is dispersed through the pelvis: basin-like shape. To house abdominal organs and muscles: muscle attachments. Gluteus maximus is farther back, behind our hips, than in apes where theirs is more to the side. Helps pull our legs up and behind us instead of out and to the side like in great apes. Also hamstrings attached more to our fibula. The foramen magnum: hole at the base of the skull where the spinal cord attaches. The spine: very s-shaped design to it in humans, two distinctive curves in the spine allows for weight to be centered around the pelvis, more bow-shaped in chimps.
