To the evolutionist, moreover, the infant exhibits a still closer kinship to the natural world. In the successive stages of fœtal development he sees the gradual unfolding of human lineaments out of a widely typical animal form. And even after birth he can discern new evidences of this genealogical relation of the “lord” of creation to his inferiors. How significant, for example, is the fact recently established by a medical man, Dr. Louis Robinson, that the new-born infant is able just like the ape to suspend his whole weight by grasping a small horizontal rod.[2] ----- Footnote 2: The _Nineteenth Century_ (1891). _Cf._ the somewhat fantastic and not too serious paper by S. S. Buckman on “Babies and Monkeys” in the same journal (1894). ----- Yet even as nature-object for the biologist the child presents distinctive attributes. Though sharing in animal instinct, he shares in it only to a very small extent. The most striking characteristic of the new-born offspring of man is its unpreparedness for life. Compare with the young of other animals the infant so feeble and incapable. He can neither use his limbs nor see the distance of objects as a new-born chick or calf is able to do. His brain-centres are, we are told, in a pitiable state of undevelopment—and are not even securely encased within their bony covering. Indeed, he resembles for all the world a public building which has to be opened by a given date, and is found when the day arrives to be in a humiliating state of incompleteness. This fact of the special helplessness of the human offspring at birth, of its long period of dependence on parental or other aids—a period which, probably, tends to grow longer as civilisation advances—is rich in biological and sociological significance. For one thing, it presupposes a specially high development of the protective and fostering instincts in the human parents, and particularly the mother—for if the helpless wee thing were not met by these instincts, what would become of our race? It is probable, too, as Mr. Spencer and others have argued, that the institution by nature of this condition of infantile weakness has reacted on the social affections of the race, helping to develop our pitifulness for all frail and helpless things. Nor is this all. The existence of the infant, with its large and imperative claims, has been a fact of capital importance in the development of social customs. Ethnological researches show that communities have been much exercised with the problem of infancy, have paid it the homage due to its supreme sacredness, girding it about with a whole group of protective and beneficent customs.[3] ----- Footnote 3: See, for example, the works of H. Ploss, _Das Kind in Brauch und Sitte_, and _Das kleine Kind_. -----
