I think my teeth resembles my cats way more than it does a deer.



The first number represents incisors, the second canines (both of which are exclusively for meat eating and serve absolutely no function for the exclusive plant eater), the second represents premolar (crushing teeth, useful to all orientations of animal), and the last represents molars. The first number is upper second is lower set.

As you can see, humans have a dental formula similar to both meat eaters and plant eaters.

It's plainly obvious. In nature, divorced of modern society and refining practices, a human has two options. 1) consume animals and live, 2) pretend to be herbivorous and starve. We simply cannot get enough energy from the abundant bulk, and fruits/nuts/berries are too scarce to ever fuel us effectively.
