> How come we aren't like chimps, with eternally shredded bodies and cheese grater abs, provided we get the protein to support them?
There are several reasons: Chimps have a higher density of testosterone receptors with a higher sensitivity than humans. Compared to humans, they are essentially roided out all the time.
Humans are also hairless endurance hunters so we naturally have much larger fat reserves (15-25% of body weight vs <10% for chimps) in order to retain body heat and have enough energy to hunt prey till they collapse from exhaustion.
