This study focuses on the development of unilineal descent, reviewing previous theories and testing additional factors to explain the relationship between unilineal descent and unilocal residence. Results suggest four key factors leading to a low association between these two variables: insufficient alternatives to unilocal residence rule, instability of communal composition, absence of sedentary settlement pattern, and small average community size. A model linking all variables from the paper is presented.

This article tests some conditions that may lead to the emergence of unilineal descent, focusing on unilocality and warfare. Unilineal descent is thought to be likely in a unilocal society without a centralized political system that is experiencing intra- or inter-societal warfare. The authors also posit that a "clan" system usually develops prior to a "lineage" system.

This paper presents research on the factors that promote romantic love as a basis for marriage in non-industrial societies. After a discussion of the previous literature on romantic love in ethnographic societies, the authors used the SCCS, EA, and data from eHRAF to create a data set of 109 cultures and then utilized multiple ordinal regression to test the relationship between different types of families and post-marital residence practices and the importance of romantic love in marriage. The findings show that monogamy is significantly correlated with romantic love, while nuclear family organization and neolocal post-marital residence are not significantly correlated. The presence of polygyny is found to lower the probability of romantic love being a basis for marriage. These findings contradict previous research, which found a relationship between non-neolocal post-marital residence and the presence of romantic love in marriage.
