Humans are weak, but that's not because we're using the energy elsewhere. We have comparable muscle mass to chimpanzees. We don't have comparable strength; our anatomy is what makes us weak, not a diversion of energy to other purposes.
- Detrytus 2y agoIt's about fast-twitch vs slow-twitch kinds of muscle fibers: the former are good for strength, the latter for endurance. We evolved to be distance runners, so our muscle composition changed, decreasing our strength.
- pixl97 2y agoChimps use something like 25% less calories than a human, so yes strength and energy usage are not strongly coupled. What makes humans weaker is less fast twitch muscle, and this gives us finer motor control.
