Morgan assumes that from the state of general promiscuity, a higher form of sexual relation gradually developed, the consanguine family. Here the marriage groups are arranged by generations; all the grandfathers and grandmothers within a certain family are mutually husbands and wives; their children constitute another cycle of husbands and wives, and again the children of these when they have attained the proper age. In differentiation then from the promiscuity prevailing at the lowest stage, we here find one generation excluded from sexual intercourse with another generation. But brothers and sisters and cousins of the first, second and more remote grades are all brothers and sisters and also husbands and wives. This family form corresponds to the system of kinship that during the first half of the last century still existed in Hawaii in name but no longer in fact. According to the American and Indian system of kinship, brother and sister can never be father and mother to the same child, but according to the Hawaiian system they may. The consanguine family also prevailed at the time of Herodotus among the Massagetes. Of these he wrote: “Every man marries a woman but all are permitted to have intercourse with her.”[5] Similar conditions Backofen proves to have existed among the Lycians, Etruscans, Cretans, Athenians, Lesbians and Egyptians. According to Morgan, the consanguine family is succeeded by a third, higher form of family relations, which he calls the “Punaluan family”--“punaluan” meaning “dear companion.” Morgan’s conception that the consanguine family, founded upon the formation of marriage classes according to generations, which preceded the Punaluan family, was the original form of family life, is opposed by Cunow in his book referred to above. Cunow does not consider the consanguine family the most primitive form of sexual intercourse discovered, but deems it an intermediary stage leading to the true gentile organization, in which stage the generic classification in strata of different ages belonging to the so-called consanguine family, runs parallel for a while with the gentile order.[6] Cunow says, furthermore: The class division--every man and every woman bearing the name of their class and their totem--does not prevent sexual intercourse among relations on collateral lines, but it does prevent it among relations of preceding and succeeding lines, parents and children, aunts and nephews, uncles and nieces. Terms as uncle, aunt, etc., denote entire groups.
