What would be different If we walked on four these days?
In: Biology
Our crania would be smaller – constricted by the fact that the hole for the spinal column would stay at the back of the head (like it is for gorillas), rather than the bottom like it is for humans. Therefore, we’d probably not be ‘human’ at all, as we understand it, due to different brain development.
Childbirth would be much easier though. Bipedalism resulted in drastic changes to the shape and size of the pelvis, making childbirth much more painful and risky.
