Chapter VIII: Some of its Effects

In doing this, natural selection has unlocked a door and let in a new set of causal agencies. As Homo Alalus grows in intelligence and variety of experience, his helpless babyhood becomes gradually prolonged, and passes not into sudden maturity, but into a more or less plastic intermediate period of youth. Individual experience, as contrasted with ancestral experience, counts for much more than ever before in shaping his actions, and thus he begins to become progressive. He can learn many more new ways of doing things in a hundred thousand years than any other creature could have done in a much longer time. Thus the rate of progress is enhanced, the increasing intelligence of Homo Alalus further lengthens his plastic period of life, and this in turn further increases his intelligence and emphasizes his individuality. The evidence is abundant that Homo Alalus, like his simian cousins, was a gregarious creature, and it is not difficult to see how, with increasing intelligence, the gestures and grunts used in the horde for signalling must come to be clothed with added associations of meaning, must gradually become generalized as signs of conceptions. This invention of spoken language, the first invention of nascent humanity, remains to this day its most fruitful invention. Henceforth ancestral experience could not simply be transmitted through its inheritable impress upon the nervous system, but its facts and lessons could become external materials and instruments of education. Then the children of Homo Alalus, no longer speechless, began to accumulate a fund of tradition, which in the fulness of time was to bloom forth in history and poetry, in science and theology. From the outset the acquisition of speech must greatly have increased the rate of progress, and enhanced the rudimentary sociality.

With the lengthening of infancy the period of maternal help and watchfulness must have lengthened in correspondence. Natural selection must keep those two things nicely balanced, or the species would soon become extinct. But Homo Alalus had not only a mother, but brethren and sisters; and when the period of infancy became sufficiently long, there were a series of Homunculi Alali, the eldest of whom still needed more or less care while the third and the fourth were arriving upon the scene. In this way the sentiment of maternity became abiding. The cow has strong feelings of maternal affection for periods of a few weeks at a time, but lapses into indifference and probably cannot distinguish her grown-up calves as sustaining any nearer relation to herself than other members of the herd. But Femina Alala, with her vastly enlarged intelligence, is called upon for the exercise of maternal affection until it becomes a permanent part of her nature. In the same group of circumstances begins the permanency of the marital relation. The warrior-hunter grows accustomed to defending the same wife and children and to helping them in securing food. Cases of what we may term wedlock, arising in this way, occur sporadically among apes; its thorough establishment, however, was not achieved until after the genesis of Humanity had been completed in most other respects. The elaborate researches of Westermarck have proved that permanent marriage exists even among savages; it did not prevail, however, until the advanced stage of culture represented by the Aztecs in aboriginal America and the Neolithic peoples of ancient Europe. As for strict monogamy, it is a comparatively late achievement of civilization. What the increased and multiplied duration of infancy at first accomplished was the transformation of miscellaneous hordes of Homines Alali into organized clans recognizing kinship through the mother, as exemplified among nearly all American Indians when observed by Europeans.

Thus by gradual stages we have passed from four-footed existence into Human Society, and once more I would emphasize the fact that nowhere do we find any breach of continuity, but one factor sets another in operation, which in turn reacts upon the first, and so on in a marvellously harmonious consensus. Surely if there is anywhere in the universe a story matchless for its romantic interest, it is the story of the genesis of Man, now that we are at length beginning to be able to decipher it. We see that there is a good deal more in it than mere natural selection. At bottom, indeed, it is all a process of survival of the fittest, but the secondary agencies we have been considering have brought us to a point where our conception of the Struggle for Life must be enlarged. Out of the manifold compounding and recompounding of primordial clans have come the nations of mankind in various degrees of civilization, but already in the clan we find the ethical process at work. The clan has a code of morals well adapted to the conditions amid which it exists. There is an ethical sentiment in the clan; its members have duties toward it; it punishes sundry acts even with death, and rewards or extols sundry other acts. We are, in short, in an ethical atmosphere, crude and stifling, doubtless, as compared with that of a modern Christian homestead, but still unquestionably ethical.
