Some bodybuilders these days look like absolute beasts. But we all know that many of them are using performance enhancing growth hormones to achieve that look, something that our ancestors surely never had. Further to that, looking like 'the hulk' doesn't not necessarily equate to being as strong. We all know some folks who are somehow just naturally very strong for their size, even if they don't necessarily appear to be, right?
If gorillas and orangutans are four to eight times stronger than similar sized humans, do you think humans from long ago naturally possessed higher strength due to muscular and bone skeletal structure? If so, do you think a gradual change in diet and/or lifestyle played a contributional role in the progressive decline of inherent human strength endowment?
