More accurately, we have flat teeth for chewing plant fiber from fruits and
vegetables. These were staples of the human diet dating millions of years
before we learned how to cultivate grains.

Yes.

Or at least most of us prefer to use our little holes for other purposes. :)
Also we have relatively compact intestinal tracts when compared to the
bloated guts of herbivores. Some herbivores even have multiple stomachs.
This difference suggests very strongly that we are not natural vegetarians;
we were selected by nature to consume a significant percentage of calories
from animal sources.
About 2-3 million years ago, our ancestors started trading in herbivorous
diets and big guts for omnivorous diets that allow for smaller guts and
larger brains.
