"Humans do not have any specialized genetic, anatomical, or physiological adaptations to meat consumption. By contrast, we have many adaptations to plant consumption. We have longer digestive tracts than do carnivores, and this allows humans to digest plants and fibers that require longer processing time. We also lack the ability to produce our own . Vitamin C is found in plants, so the fact that we cannot make our own, indicates just how reliant upon plants we actually are. This is why we have trichromatic vision. This is very different from carnivores, which have dichromatic vision. We can see more colors and this is very important, especially if you need to find fresh, ripe fruit."
