THE STRUCTURE OF SELKUP ETHNOS IN ETHNOGRAPHIC DESCRIPTIONS
Names of Selkup clans reflect the dual and triadic arrangement of their marriages. Historically, the dual worldview pre-dated the triadic one. In the system of family relations, the dual worldview corresponded to group marriages, whereas the triadic worldview corresponded to circular ties and transition from matriarchal linearity to patriarchal linearity. Matriarchate complied with the horizontal view of the world, and with the transition to patriarchate, the view of the world became vertical.
