also i missed the whole herbivore thing but that is absolutely false; we evolved to be omnivorous to take advantage of the unique nutrients available from both plants and animals, but meat provides significantly more energy, which was a necessary development to pave the way for more complex, power-hungry brains. cooking isn't a loophole in our diets, it's a tactic we developed to unlock nutrients in our food and become more successful as a species. contending that we are 'biologically herbivores' is simply false; plants do not conveniently provide all the proteins we need for survival (in the wild at least, modern economic and technological developments make vegetarian and vegan diets much more viable)
(disclaimer here being that i'm not qualified to talk about biology, but i know enough to understand that the idea that we're meant to be herbivores is asinine)
