timepoints a réagi à votre billet :actually the knee stuff is true lucy’s bicondylar…b idk what bacons is
it’s the angle your thigh bone makes with your shin!!
ours comes in at an angle so our legs can swing underneath the bottom of our pelvis but if it was a straight line (like in chimps) it would have to stick out to the side a little bit and walking upright would be harder
actually the knee stuff is true lucy’s bicondylar angle is like intermediate between ours and a chimp’s so clearly she was at least partially bipedal but i am v doubtful about that graphic
