Nature has divided the entire animal kingdom, including human beings, generally into three categories – carnivore, herbivore and frugivora. All flesh-eating animals like the tiger, panther, leopard, hyaena, cat, wolf and jackal, birds like the hawk and vulture and certain reptiles are carnivorous by nature. The elephant, bison, camel, horse, cow, buffalo, sheep, goat, deer and hare are examples of herbivorous animals which eat and live upon grass or herbaceous vegetation, leaves of trees, etc. Frugivorous animals are those that feed on fruits, flower, seeds, roots, tubers, leaves, stalk, etc., and various cereals. Most of the birds, the monkey specie and human beings fall into this category. As a matter of fact the bodily constitution, hands, fingers, nails, mouth, lips tongue, teeth and the digestive system, in short the entire physique of a human being is suited only to vegetable-eating and not to flesh-eating. Man is thus by his very nature a frugivore, not a carnivore. Numerous physiologists, medicos, dieticians and other specialists, from the west also, have endorsed this view. Even Charles Darwin who, in his theory of the ‘Origin of Species’, propounded as the basis of evolution ‘the struggle for existence’ and ‘the survival of the fittest’, implying that the stronger always kills and devours the weaker specie, admits in his ‘Descent of Man’ (p.156) that in early times a very large number of human beings were vegetarians. He was very much astonished to see that the Chilean miners were extraordinarily robust., vigorous, tenacious and strong, and that they were all vegetarians| His contemporary, prince Kropatkin, also a g reat revolutionary thinker, countered Darwin’s ‘survival of the fittest’ theory by proving that not force of violence, but the capability of co-operation and co-existence has been the cause of the success or survival of life and the species in the evolutionary process. It is also a fact that man’s nature, physical equipment and requirements should make him a vegetarian only a small fraction of world’s population has been and is pure vegetarian, that is, fruitarian, vegan-vegetarian or lacto-vegetarian. But , the number of those who are totally non-vegetarian and live wholly on flesh food is still much smaller. By and large, the majority of human beings live on a mixed diet, the proportion of vegetable to flesh food differing from region to region, race to race, society to society and individual to individual.
