CHAPTER VI
PARENTHOOD AMONG THE HIGHER ANIMALS
THE FIXING OF THE PARENTAL INSTINCT IN THE MOTHER

“The universe throbs with restless change. Everything that we know is becoming rather than being.”—P. Chalmers Mitchell

One of the difficulties that has met me in my studies of the family among the animals is that, as we ascend the scale of life, there is a moral retrogression in fatherhood—at least, that is how it appears to me. There are, as far as I have found, no examples among mammals, the highest and last group of the animal kingdom, of devoted fathers undertaking the sole charge of the young, and few where the father even shares with the mother to any extent in the work connected with the upbringing of the family. The egoistic desires seem to increase in the males, with a corresponding weakening of their interest in the family and willingness to participate in its duties. The young are carried by the mother alone, they are protected chiefly by her; the father takes no part in the nursery cares, and rarely does he help in providing food for the children. The family is maternal, the female—the mother—its centre; the male is bound sexually to the female, but apart from this his connection with the family is slight; we find him most frequently following personal interests.

In contrast with the conduct of the fathers in the families we have so far examined among the birds, reptiles, fishes and insects, with whom the father’s solicitude and sacrifice for the young equals and, in some cases, rivals that of the mother, this complete paternal indifference is really very startling. It demands our attention.

What factors have brought about this reversal, which at first sight appears so strange? Why is it that the parental instinct diminishes in the father and is now fixed in the mother? It is, however, easy to understand this change if we consider what now happens, and the changed conditions under which the young are born. The mammals do not lay eggs like bird and reptile mothers, but each mother retains the eggs within her body, and so secures for the young warmth and protection far more certainly than would be possible in the best-contrived nest or home.[47] But this has led to changed habits. No nest or brooding-home has to be made, and the same preparations for the family, which hitherto have united in work the father with the mother, are unnecessary. Again, food has not now to the same extent to be collected and stored in readiness for the future needs of the children. The embryo, living within the body of its mother, gains the food for its growth directly from her blood. The connection between mother and child now is closer; her condition and health become of direct importance for the welfare of the young. At the same time the importance of the father is sharply lessened. This is plain. The early stages of mother-care, instead of being conscious and external acts regulated by special circumstances and often modified to meet different needs, now become part of the unconscious functions of the body of the mother—the child is an extension of herself. The advantage to the offspring of this change from external to internal protection is great, in the added safety thereby gained from fixed functions over the habits that might be slurred over, bungled or forgotten. I think, however, that there is a corresponding loss—that parenthood becomes more possibly irresponsible and, at the same time, individualism becomes stronger. Birth, with narrowed opportunity for intelligent adaptation, is more of an unconsidered incident; I mean that before it occurs it demands much less from the parents in sacrifice and in work. This is certainly the case with the father, whose part in gaining offspring is reduced to a single momentary act, and one, moreover, that is prompted by the fiercest egoistic desire.

But I think, too, there is a deterioration, though much less in degree, in the quality of motherhood. The preparation made for the birth of her children by the mammal mother is very slight, indeed, in many cases the mother appears to be unaware of the approaching event until the actual birth begins. Here is an account of a langur monkey, whose first baby was born in the London Zoological Gardens, at which event the mother seemed to be utterly surprised. The birth took place at night, and the mother, from the marks in the cage, must have dragged up and down the new, astonishing object. But by the morning she had grown accustomed to the baby, and held it pressed closely to her breast, from time to time thrusting the head outwards and eagerly looking at it. For several weeks the baby never left her, and she showed endless curiosity and pleasure in it, ceaselessly examining it, turning it over, stroking it and keeping it clean with her hands. She was jealous of visitors, and when they came near to the cage she would turn round so as to hide the baby from them. The father, in case of accidents, had been taken away and put in the adjoining cage, which was shut off by a piece of canvas. He made a hole in this, and from time to time, especially when the mother or baby made any noise, he would raise the torn flap and peep through.[48]

It must be remembered that among the mammals it is the rule for the young to be suckled by the mother, a mode of feeding already foreshadowed by many bird parents and some insects. But with them the special nursery food is prepared from their own food by incessant work, undertaken, as a rule, by both parents. The act of suckling, on the other hand, occurs without conscious work, and is a function in which the father has no concern whatever.

I have no facts to trace the steps whereby this function of maternal feeding was developed and established, but I would suggest that, apart from the advantage to the young of a special diet, the immense labour entailed on the parents in obtaining food—the foraging over wide areas and the carrying of the provisions back to the nursery—made it a question of economy; and that the mother, as more usually being with the young, was the parent who came without conscious effort to prepare for them in her body this early nourishment.

It is plain that the bond between the mother and offspring would be greatly strengthened; they would be dependent upon her alone, and drawing life from her body, she would become increasingly conscious of them during a much longer period. The emotional quality of affection really develops now. The suckling is a continuation of the organic relation by which the child is born of the mother’s body; now the child exists through her, and becomes, so to speak, a habit which grows up out of her own individuality. I lay stress upon this fact: the maternal feeding is the beginning of a new period in the growth of motherhood, and is the foundation of the indestructible bond between mother and child.

We see, then, the reasons for the curious and sudden deterioration in fatherhood; the father has, as it were, been pushed out of his earlier position of service. Now that there is no nursery to be built, and the mother is the sole feeder of the young during their period of greatest helplessness, the father loses his interest in the family. Our interests and our habits are fixed by whatever occupies our attention. Freed from the first and most important care of the young, the male is severed from the family and its duties, and his attention, thus set free, turns in new directions and centres upon himself. In this connection we have, I would suggest, an explanation of the greater variability of the male as well as of his more violent passions. Instead of a working partner with the mother, sharing in her sacrifice for the welfare of the family, he is a member apart; he grows larger than the female, becomes masterful, pugnacious, jealous of her and of the young: a fighting, egoistic specialisation. He is still attached to the female, but he seeks her to satisfy his sexual needs, he less frequently remains with her as a domestic partner, relieving her in connection with the rearing of the young.[49]
