- Humans exist as frugivores -

"All available scientific evidence indicates that humans are frugivorous apes. Regardless of how large and arrogant our cultural egos are, and regardless of unsupportable religious dogma created by ignorant people who knew absolutely nothing of biochemistry, comparative anatomy, genetics, or science thousands of years ago, our physiology is that of a frugivorous ape."--Laurie Forti

“I do not intend to enter into any lengthy discussion of comparative anatomy and physiology at this place, but will content myself with saying that every anatomical, physiological and embryo-logical feature of man definitely places him in the class of frugivore. The number and structure of his teeth, the length and structure of his digestive tract, the position of his eyes, the character of his nails, the functions of his skin, the character of his saliva, the relative size of his liver, the number and position of the milk glands, the position and structure of the sexual organs, the character of the human placenta and many other factors all bear witness to the fact that man is constitutionally a frugivore. As there are no pure frugivores, all frugivores eating freely of green leaves and other parts of plants, man may, also, without violating his constitutional nature, partake of green plants. These parts of plants possess certain advantages, as has been previously pointed out, in which fruits are deficient. Actual tests have shown that the addition of green vegetables to the fruit and nut diet improves the diet.” - Herbert M. Shelton

"To say that humans have the anatomical structure of an omnivore is an egregiously inaccurate statement. The great taxonomist Carolus Linnaeus, (1707-1778), a Swedish naturalist and botanist who established the modern scientific method of classifying plants and animals, classified humans not as carnivores, not as omnivores, nor even as herbivores, but as frugivores. Linnaeus writes: “Man’s structure, internal and external compared with that of the other animals, shows that fruit and succulent vegetables are his natural food.” A few anthropologists have risen above their biases; one such is Jared Diamond, a professor of anthropology at UCLA. Diamond has written [pdf] that the notion of man the hunter is a romantic myth: “big-game hunting added little to our food intake until after we had evolved fully modern anatomy and behavior.” Instead, our earliest ancestors lived on the wild fruit, nuts, seeds and tubers that they gathered. Mr. Diamond puts it succinctly: “I doubt the usual view that hunting was the driving force behind our uniquely human brain and societies. For most of our history, we were not mighty hunters but rather sophisticated baboons.” And what food makes up the bulk of baboon diet? Fruit, of course; so for most of their history, humans were fruitarians."-----Rynn Berry

"The natural food of man, judging from his structure, appears to consist principally of the fruits, roots, and other succulent parts of vegetables. His hands afford every facility for gathering them; his short but moderately strong jaws on the other hand, and his canines being equal only in length to the other teeth, together with his tuberculated molars on the other, would scarcely permit him either to masticate herbage, or to devour flesh, were these condiments not previously prepared by cooking." - Georges Cuvier (1769-1832), Regne Animal, Vol1
