It seems certain that the whole truth regarding the problems of kinship, as well as regarding the rise and sequence of the forms of the family, can be reached only through a thorough historical investigation of the industrial habits of mankind. In fact, the position of Starcke, that the rise of rules of descent and kinship depends mainly on economic and local causes, is strengthened in a remarkable way by the researches of Grosse, which have already been presented in outline. Nowhere does promiscuity appear among the peoples known to history or ethnology; and everywhere, even among the "lower hunters," comprising the most backward members of the human kind, appears the single family in which the man holds the place of power, which is often despotic. There is no definite sequence between the maternal and the paternal systems. The existence of either depends upon favorable economic conditions; and they may both appear side by side. In fact, according to Cunow, among the lower hunters, with the single exception of the Australians, the custom of female descent has not yet been discovered; and even in Australia it is precisely the most advanced tribes among which the maternal system appears. It first arises when women are sought outside of the original horde, in order to prevent intermarriage of maternal kindred.[353] [353] See CUNOW, "Die ökonomischen Grundlagen der Mutterherrschaft," _Neue Zeit_ (1897-98), XVI, 115, 113, 14, reviewing and supplementing GROSSE'S _Die Formen der Familie_, summarized above. The investigations of Hildebrand, elsewhere mentioned, tend in the same direction. In the light of present research, therefore, the most that can safely be admitted concerning the system of kinship through females only is that it has widely existed among the races of mankind;[354] although, as elsewhere shown, its prevalence has been greatly exaggerated. Partially under the influence of monogamy and the rise of modern forms of property, it has often been superseded by the parental and sometimes by the agnatic system, although this sequence is by no means invariable. It is very archaic, yet not necessarily primitive. There is no satisfactory evidence that it implies an original stage of promiscuity. It is not impossible, in view of the facts disclosed by Starcke, that sometimes it may be preceded by a custom in which the child is named from the father, and rank and property descend in the male line; while there is evidence that in the lower hunting stage, before rules of descent were yet subjects of reflection, a kind of patriarchate or androcracy generally prevailed.[355]
