Very big caveat: while our primate cousins manage to eat some meat from time to time, it was our domestication of fire more than a million year ago that allowed us to access plenty of calories and nutrients from almost any food, everything was suddenly on the table, and was made easy to chew and digest. We are more omnivorous than the naturally omnivorous animals.

That's really neat but my god is it ugly

First off, this chart seems to be rather cherry-picked, with some information just outright wrong. When corrected for body size, the human digestive tract is significantly shorter than herbivores and longer than carnivores. That suggests that we're omnivores.

Second, explain how humans have binocular vision, a trait common to every land-based carnivore and omnivore.
