None of these peculiarities of human family life are found in the family life of any animal species below man. It might seem, therefore, that man's family life must be regarded as a special creation unconnected with the family life of the brutes below him. But this view is hardly probable, rather is impossible from the standpoint of evolution. We must say that these peculiarities of human family life are to be explained through the fact that man has passed through many more stages of evolution, particularly of intellectual evolution, than any of the animals below him. If we examine these peculiarities of man's family life carefully, we will see that they all can be explained through natural selection and man's higher intellectual development. That man has no pairing season, has fewer offspring born, and a longer period of dependence of the offspring upon parents, and the like, is directly to be explained through natural selection; while seeking the indorsement of society before forming a new family, sexual modesty, tendencies to artificial adornment, and the like, are to be explained through man's self-consciousness and higher intellectual development, also through the fuller development of his social instincts. The gap between the human family life and brute family life is, therefore, not an unbridgeable one. That this is so, we see most clearly when we consider the family life of the anthropoid or manlike apes--man's nearest cousins in the animal world. All of these apes, of which the chief representatives are the gorilla, orangutan, and the chimpanzee, live in relatively permanent family groups, usually monogamous. These family groups are quite human in many of their characteristics, such as the care which the male parent gives to the mother and her offspring, and the seeming affection which exists between all members of the group. Such a group of parents and offspring among the higher apes is, moreover, a relatively permanent affair, children of different ages being frequently found along with their parents in such groups. So far as the evidence of animals next to man, therefore, goes, there is no reason for supposing that the human family life sprang from confused or promiscuous sex relations in which no permanent union between male and female parent existed. On the contrary, there is every reason to believe, as Westermarck says, that human family life is an inheritance from man's apelike progenitor.
