What other living species are omnivores?[/i][/b]
Bears, chickens, pigs, rodents, foxes, racoons (bears), opossums, many birds, beetles, many of the order hymenoptera, flies....etc...... Why were we asking this again?
A human being digestive system is quite different from a carnivores digestive system. Along with other differences that are in a sharp contrast.
Our digestive system is much different than that of herbivores as well. Look at animals like the ruminants with their 4 chambered stomachs used to break down the cellulose from plants. Our body can't digest cellulose and just "passes it through".
Now I do agree that humans can eat meat and that is because of the strength of our bodies, however strength does have a tolerance and eventually it deterioates.
No, we can eat meat because thats how we evolved. Meat is one of the best sources of essential a(essential means nutrients that must be attained in preassembled for because out body cant build them from their simpler components) amino acids because the protein has every single amino acid we need. Now, we can get those amino acids from non-animals, but the diets must be varied in order to properly supplement all of the bodies needs. (even though one can get all of them from just beans and corn)
