for the young, and shown that such care and sacrifice is shown frequently by the father.

      

      Let me summarise now what we have learnt in this and the preceding chapter, so as to establish the lessons that seem to me may be taken from these pre-human parents. The diversity in the expression of the parental instincts must first be grasped. There is no fixed order, nor does there seem to be any continuity of development in this matter of care for the young. We have to give up quite the evolutionary idea of a certain and uninterrupted progress. Throughout our inquiry we have been met with surprises. These things baffle our attempts to find an explanation. What is it that decides and develops the strong instinct of parenthood? A parent in a species that is lower in the scale will often have more parental feeling than a parent in a higher species. Why, for instance, is the stickleback such a devoted father; more self-sacrificing than any other fish-father? and why is the stickleback mother without regard for her children? Why among the dung-beetles is the same parental sacrifice shown by both parents? Again, why is a nursery made in some cases and not in others? why are the young guarded sometimes by the mother and sometimes by the father? We may say that all this wide diversity in habits has arisen through adaptation; the circumstances that have conditioned the life of the species have been different, and this has necessarily caused variety in their behaviour. This is, of course, true, but does it really teach us very much? No sooner do we begin to apply our reasons to any particular case of family behaviour than we find ourselves at a loss. Our reasoning suddenly breaks down, either because our knowledge is incomplete, or because one set of facts we possess seem to be contradicted by other facts of which we are equally sure.

      

      Let us at once acknowledge our ignorance; there is much that cannot be explained.

      If, however, we speculate at all on the matter, certain general ideas may be suggested. We are led to the view that when the father undertakes the care of the young, this reversal in the family duties must be primarily due to some failure on the part of the mother in performing the work in the nursery and home which customarily is hers. It is as if the father steps into her place in order that the species may escape the nemesis of elimination. The facts we have learnt are of no little importance. They tend to minimise, in the beginning of the family at least, the importance of the mother in relation to the young as compared with the importance of the father. It is this that I wish to establish.

      And what we have learnt suggests the further interdependence, that does seem to exist among all species, between intelligence and good parenthood. Fabre, out of his wisdom and as a result of his great knowledge, says that the duties of caring for the young are the supreme inspirers of the intellect. Wherever we find devoted parents there also do we find lofty instincts. This is the second idea I ask you to accept. I think that we have proved its truth.

      I may not stay here to point out the immense importance of these suggestions to the inquiry we are making as to the action of the maternal instinct, nor shall I pause to indicate the lessons that seem to me to await us from the curious transformation found in so many species in the duties of the two sexes. These considerations must wait until we know more. We have, I trust, extended somewhat, as well as rendered more exact, our knowledge on this complex and difficult question of motherhood. In the next two chapters I shall endeavour to extend it still further by a brief consideration of certain striking habits I have met with of parenthood among the birds and higher animals.

      I am well aware that there are many people who cannot bring themselves to believe in, or even listen without impatience to, any comparison between the conduct of animals and that which prevails among ourselves. It is absurd, they will say, to try to explain the conditions of human parenthood by references to animal parents. I have no hope of convincing, nor do I much desire to convince, those who thus object. I would merely advise them to leave out this section of my book altogether.

       PARENTHOOD AMONG BIRDS

       WITH FURTHER EXAMPLES OF GOOD FATHERS

      For life and joy, and for objects and knowledge curious.”

      Walt Whitman.

      Two things I have been anxious to bring out prominently in the foregoing chapters: that parental behaviour among the insects, reptiles and fishes presents us with a bewildering diversity of aspects—in particular, that the instinct of caring for the young is not fixed in the mother, but may be transferred from her to the father; and further, that all parental sacrifice, though often unconsciously expended to maintain the well-being of the family, is of direct benefit to the parent who bestows it, and is the surest means of developing and brightening such a parent’s individual intelligence.

      Now, I wish to elaborate and establish these two propositions with further examples in order that they may be laid hold of and firmly grasped as indubitable facts; and then we may come to see and understand the significance to ourselves of these unusually devoted fathers, which are found, and that not infrequently, among all classes of pre-human parents.

      The varied behaviour of bird-parents—more especially of the males—furnishes just the kind of evidence we need. There are several cases known, and I believe there must be others as yet unrecorded, wherein the conduct and, indeed, the whole character of the two sexes is reversed. Here the females, driven it would seem by a fierce sex-hunger, do the courting and fight one another as rivals for the males, while the males undertake all the family duties of incubation and brooding and the feeding of the young.

      The phalaropes, both the grey and the red-necked species, which are found in Scotland and Ireland, afford a striking example of these unsexed females. Among these birds the rôle of the sexes is reversed. The duties of incubation and rearing the young are conducted entirely by the male, and in correlation with this habit, the female does all the courting. She is stronger and more pugnacious than the male, and is also brighter in plumage. This is really very remarkable. What has acted in bringing about this reversal in the secondary sexual characters? Can the male nature be transferred to the female? These are difficult questions. In colour the phalaropes are a pale olive very thickly spotted and streaked with black. The male is the psychical mother, the female takes no notice of the nest after laying the eggs. Frequently at the beginning of the breeding season she is accompanied by more than one male, so that it is evident polyandry is practised.[30]

      The same unusual family conditions prevail with the rhea and the emu, and also among the painted snipes, cassowaries, tinamous, and some of the button-quails.[31] There are probably instances of other birds, but I do not know of details of their habits; Wallace[32] also mentions several species in different parts of the world, among whom all care of the young falls entirely upon the father. In all these bird families exactly opposite conditions prevail to what we are accustomed. It should be specially noted that these unnatural (I use the word simply to mean unusual) mothers are larger and more vividly coloured than the hard-worked fathers; in all such
