NATURAL SELECTION AND SURVIVAL OF THE FITTEST would have any chance of survival in that hostile climate, continuously, generation after generation, without becoming extinct. If they could do so with a fair guarantee for the survival of the species, the evolutionary exercise of the polar bears would be rendered superfluous and the characteristic changes brought about in features could no longer be considered as necessary. . Now we look at the same scenario from a slightly different angle. It is impossible for the extremely inhospitable environment, such as obtains in the arctic region, to work causatively for bringing about appropriate changes to the biochemistry of cells. Yet, without such profound changes in the character bearing genes, no gradual or mutative changes can be visualized. White fur upon black skin, taller hindquarters and shorter forequarters, tiny rounded ears, an exceptionally sharp sense of smell and vision, thick fur under the soles of their paws, change of coats in accordance with environmental dictates and layer upon layer of fat under the skin, cannot be made to order by the climatic conditions prevailing in the arctic habitat of the polar bears and foxes. Chance must continue to play its role separately and blindly in the cellular chemistry to add variety to characters and to bring about spontaneous changes in animal features, haphazardly in every direction. . Natural selection must wait for these painstakingly slow changes to provide a large variety of options for it to choose from. For instance, if random changes in the cellular chemistry can suddenly alter the colour of hair from black to white, with a thick layer of white fur added on top of that, why cannot they change the colour of the hair from black to blue or red or crimson or violet or green or deep yellow or saffron for that matter? How did cellular chemistry know that what was needed in the arctic climate 438
