I mean that was my original point but I don’t think I portrayed that correctly at all early humans lived hunter gather life styles I think that’s quite obvious at this point especially with all the scientific evidence pointing toward it plus moving around alot across continents and having to go out and hunt fish and forage for there food meant that they were way healthier stronger and fitter as you said as there getting a healthier diet and lots of exercise
what op said that for billons of years we lived of “beans and rice” which makes no sense whatsoever although I could be wrong I know beans on there own have a good selection of the nutrients you’ll need to sustain yourselve but im not to sure on rice plus I’m fairly certain you can’t eat rice and beans forever you’ll have to supplement it with something as well
Plus I haven’t read anywhere about humans sustaining themselves for billons of years on just a diet of beans and rice
