There are as many (or more) studies indicating that human coprolites contained more plant than animal matter. It seems it would depend largely on the season, climate, location, and other factors. Some human populations had little to no reason to hunt. Others more recently would have needed to hunt due to relentless cold conditions from long winters. We are opportunistic and diverse feeders. It doesn’t seem like there’s a clear advantage to eating animals outside of calorie density and availability when plants are absent. It seems more helpful to view meat eating simply as diversification. Our plant based diets would have supported large brains, and they still do. There’s no clear reason to believe that eating other animals enlarged our brains.
