Our species may indeed be evolving, however slowly, but I don’t think we’ll go from being the carnivores that we are to being herbivores. Sorry vegans, it just wasn’t meant to be.
On one hand leftists/vegans tell us we're all just animals like other animals. But many animals are carnivores or omnivorous.
It was a huge shock to the food nazis when they found out chimps eat meat. I doubt chimps were unable to eat veggies. They like meat. Like we do...because we've adapted to eating meat from the earliest days of man.
The food nazis might as well tell lions, tigers, bears, etc., to stop eating meat, because it would make about as much sense as telling homo sapiens to stop eating meat.
