The very significant counter-fact, however, remains, that none of the actual anthropoids, as far as regards the adult males, are in any way social or even gregarious; the conclusion thus seems evident that, like these his nearest compeers of to-day, man was on the contrary a non-social animal, and that, as with the gorilla, only one grown male would have been seen in a band. We must then imagine our more or less human ancestor, roaming the forest in search of daily food, as a solitary polygamous male, with wife or wives and female children; the unsocial head of a _solitary_ isolated group. With equal strength and probably already greater cunning than any _actual_ animal of to-day, he had perhaps acquired dominance over most of the other beasts of the field. The patriarch had only one enemy whom he should dread, an enemy with each coming year more and more to be feared--deadly rivals of his very own flesh and blood, and the fruit of his loins--namely, that neighbouring group of young males exiled by sexual jealousy from his own and similar family groups--a youthful band of brothers living together in forced celibacy, or at most in polyandrous relation with some single female captive.[1] A horde as yet weak in their impubescence, they are, but they would, when strength was gained with time, inevitably wrench by combined attacks, renewed again and again, both wife and life from the paternal tyrant. But they themselves, after brief communistic enjoyment, would be segregated anew by the fierce fire of sexual jealousy, each survivor of the slaughter relapsing into lonely sovereignty, the head of the typical group with its characteristic feature of a single adult male member in antagonism with every other adult male. Now it can be shown that this vicious circle of the stream of social life is common to most mammals. The facts of the circumstance can be most easily observed amidst the half-wild, half-domesticated animals met with in colonial farming experience, in New Caledonia, for instance, where European horses and cattle have been allowed to return almost to a state of nature. In this respect the economy of life in a herd of even such gregarious creatures as the bovine race, is a very curious and instructive study. There is no fact more striking than the subordination in which the younger bulls are kept; as long as they are at all tolerated in the herd by its patriarch, their intercourse with the females is most limited, and only takes place by stealth and at the risk of life and limb.
