There’s one thing that makes me feel us humans have some thing just a little strange about us and evolution has some to do with it.
Have you ever seen a person with very flat teeth that resemble simple herbivores teeth? Have you ever seen some one with very sharp K-9 type teeth?
What would cause this?
I am assuming and most will that there ancestors ate a lot of X kind of food. Then agen threw out history we see a mix of vegetable and meat diets not many meat or vegetable diets only. Even if a few generations where to take up a meat only diet it wouldn't cause a evolutionary response as to grow sharp K-9s.
Maybe we are closer or further apart from another. Imagine if some one told you some of us are the rabbits others the wolves? Did we always have a genetic marker that makes some of us herbivores and the rest carnivores?
I'd say someone with canine type teeth doesn't brush often enough.

People are not either carnivores or herbivores by necessity, we choose these existances. We are all omnivores, like it or not vegans. Meat gave us a developed brain. I'll keep eating it thanks very much. We were meant to eat it.
Nearly all plant eaters have fermenting vats (enlarged chambers where foods sits and microbes attack it). Ruminants like cattle and deer have forward sacs derived from remodeled esophagus and stomach. Horses, rhinos, and colobine monkeys have posterior, hindgut sacs. Humans have no such specializations.
Although evidence on the structure and function of human hands and jaws, behavior, and evolutionary history also either support an omnivorous diet or fail to support strict vegetarianism, the best evidence comes from our teeth. We're all equipped with an all-purpose set of ivories equally suited to steak and onions.
