"How many times, for instance, have we not heard people speak with all the authority of conviction about the “canine teeth” and “simple stomach” of man, as certain evidence of his natural adaptation for a flesh diet! At least we have demonstrated one fact; that if such arguments are valid, they apply with even greater force to the anthropoid apes—whose “canine” teeth are much longer and more powerful than those of man ... And yet, with the solitary exception of man, there is not one of these last which does not in a natural condition absolutely refuse to feed on flesh! M. Pouchet observes that all the details of the digestive apparatus in man, as well as his dentition, constitute “so many proofs of his frugivorous origin”— an opinion shared by Professor Owen, who remarks that the anthropoids and all the quadrumana derive their alimentation from fruits, grains, and other succulent and nutritive vegetable substances, and that the strict analogy which exists between the structure of these animals and that of man clearly demonstrates his frugivorous nature. This is also the view taken by Cuvier, Linnæus, Professor Lawrence, Charles Bell, Gassendi, Flourens, and a great number of other eminent writers."
