The evolution of man from his animal ancestry has been a composite phenomenon, one by no means confined to the physical and intellectual conditions which we have so far considered, but embracing also features of moral and spiritual progress. The origin and growth of these need also to be reviewed, if we would present a fully rounded sketch of human evolution. So far as his physical form is concerned, man became practically completed ages ago, as the supreme effort of nature in the moulding and vitalizing of matter. When the arena of the struggle for existence became transferred from the body to the mind, variation in the body, once so active, rapidly declined; and with the full employment of the intellect in the conflict with nature, physical evolution ceased, except in minor particulars, and the organic structure of man became practically fixed. The human animal, therefore, as a physical species, has reached a stage of permanence. And this may be regarded as the supreme result of material evolution in animals; or at least it may be affirmed that, while man continues to exist, no member of the lower animal tribes can possibly develop to become his rival. But though man is not markedly distinct as a physical species from his anthropoid ancestor, the process of evolution has not ceased, but has gone on in him rapidly and immensely. The strain has simply been transferred from the body to the mind, and to the extent that the mental characteristics are more flexible and yield more readily to formative influences, the mind has surpassed the body in rapidity of evolutionary variation. Within a period during which the lower animals have remained almost unchanged, man has varied enormously in mental conditions, and to-day may be looked upon, not merely as a distinct species, but practically as a new order, or class, of animals, as far removed intellectually from the mammals below him as they are from the insects or mollusks. If now we turn from the physical and intellectual to the ethical stage of development, it will be to perceive as marked and decided a process of evolution. The change has, perhaps, been even greater, since in the lower animals the moral faculties are more rudimentary than the intellectual. But, on the other hand, the moral development in man has been much inferior to the intellectual. Therefore, though the foundation was lower, the edifice has not reached nearly so great a height, and man to-day stands in moral elevation considerably below his intellectual level.
