Human culture may have treated meat as a natural food source, but we haven't evolved to handle it as a major food source. Meat eating species have mostly sharp teeth, but humans mostly have flat teeth with sharp in the front to rip vegetation. Meat eaters have natural enzymes in their stomaches to eliminate germs, but us humans must cook it. Meat eaters also have short intestines to quickly eliminate the high fat content. Humans have very long intestines to absorb nutrients from plants. Go to youtube and type in Vegan Video. Very good info.
Lolwut. Incisors are for tearing meat, not vegetation. What plant could you possibly eat only with your incisors?
Humans are hybrids. We eat meat, and plants.
What do you think those arrow heads found in archeological digs? Stabbing vegetables? Meat eating is a natural part of life.
If you're an evolutionist, you believe we evolved from ape-like creatures. Apes in the wild eat meat, too.
