For a much more cogent reason, the development of the moral sense in the savage cannot be accounted for by considerations taken from _utility_, whether _individual_ or _collective_. Wallace insists upon this point at some length; he quotes examples which prove that this feeling exists, in all which is most delicate and most opposed to utilitarian notions, among the most savage tribes of Central India. We could give many examples of this fact; among others, that the Red-skins have the greatest respect for their word of honour, though it should entail torture and death. Our author bases numerous arguments upon the physical examination of man. “It is perfectly certain,” he says, “that natural selection could not have produced the present naked body of man from an ancestor covered with hair, for such a modification, far from being useful, would be injurious, at least in certain respects;” in civilised man a number of movements are executed by the hand of which savages have not the slightest idea, although no anatomical difference exists in the structure of the superior members; the larynx of our singers is constructed similarly to that of savages, and, nevertheless, what a contrast between the sounds produced! From all these facts Wallace concludes that the brain, hand, and larynx of savages possess _latent aptitudes_, which being temporarily _useless_ cannot be attributed to _natural selection_. Man, moreover, has not the power of acquiring them himself. Foreign intervention therefore is necessary, for the explanation of their existence. Wallace attributes this intervention to a _superior intelligence_ which acted on the human species, just as the latter has acted on the rock-pigeon to produce from it the pouter or the carrier, and which employed analogous processes. In short, _natural selection_, regulated by the laws of nature only, is sufficient to produce wild species; _artificial_ or _human selection_ can produce improved races of animals and plants; a kind of _divine selection_ must have produced the present man, and can alone bring him to the highest pitch of intellectual and moral development.
