, ''Cross-Cultural Research: the Journal of Comparative Social Science'' 37/1 (2003), p. 132–156. on the unilineal descent organization has studied variables that are usually regarded as the main causes of the decline of unilineal descent organization – viz. statehood, class stratification and commercialization – along with one not previously considered: deep Christianization, defined here as having been Christianized over 500 years before ethnographic study. The research demonstrated that the traditionally accepted causes of the decline are less significant than deep Christianization, while the presence of unilineal descent groups correlates negatively with
