Reply to comment by FillRevolutionary900 in I saw in a video that chimpanzees and gorillas do not knuckle-walk in the same way, but they didn't explain what the difference is. Could someone elaborate on the physiological/anatomical differences? by [deleted]

We don’t seem to have gone through a knuckle-walking stage (the ancestors of gorillas, chimps, and humans became terrestrial independently of one another), so our clavicles never had to support much body weight.
