We've all seen the pictures - crawling monkey to hunched ape, to slouched neanderthal, to upright man.
I've been trying to walk with better posture for a couple of days, and it's actually quite uncomfortable.
If you're just a little bit slumped, it feels a bit easier on the body, and you have a lower centre of gravity - better for scrambling around quickly and for stability.
So where's the evolutionary advantage in standing completely upright?
