Reply to comment by waterslidelobbyist 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]

But that makes the statement distinguishing the terrestrial apes and arboreal apes in terms of the shape of their clavicles meaningless. Because there are really only two terrestrial apes (gorillas and humans), and one of those two doesn't fit what the statement claims. So why make that distinction in the first place.

I'm honestly not smart enough to explain the distinction but I'll try. We're one of the two terrestrial apes now, but in the Miocene we've got a whole grip of weird apes running around Africa and Eurasia on the ground, and they're all more closely related to gorillas and have similar adaptations.
