This paper describes a typology which is intended to indicate the kinds of family and kinship structures associated with the conflicting requirements of cohesion and differentiation of broader social structures.

This article presents a reanalysis of the theory put forth by Hartung (1981) regarding the relationship between inheritance and paternity confidence. The authors take issue with the original sample used and retest the hypothesis.

Using paternal investment theory, the authors examine the relationship between paternal confidence and paternal investment in humans.

This study examines cross-cousin marriage preferences from an evolutionary perspective. Results suggest significant associations between cross-cousin marriage preferences and both polygyny and residence.

This article tests hypotheses related to kinship terms, cousin marriage, and descent rules. Omaha, Crow, Eskimo, and Iroquois systems are each significantly associated with different kinship rules. Material from Northern Ghana is also considered.

This article reviews the theory that permanent animal groups have only one sex breed outside the group in order to balance genetic diversity and group relatedness. The author theorises that since males inherit valuable membership in patrilocal/lineal societies, they are expected to be more concerned about the probability of paternity than males in matrilocal/lineal societies. Moral rules, and specifically belief in moralizing gods, are expected to reflect this difference. In other words, moralizing gods are used to restrict the sexual activity of women.

The present study aims to evaluate correlations of private property from two of Murdock's datasets, one of 147 societies (1981) and the other of 312 societies (1967). Altogether the author tested 146 variables coded by Murdock against variables regarding the ownership of land and of movables drawn from Murdock (1967), Simmons (1937), and Swanson (1960). In total, there were 51 statistically significant correlations between private property ownership and other variables. Additionally, the author summarizes the results from this article and the two that preceded it stating that throughout all of the correlations he ran, the practice of agriculture, the use of cereal grains, and the presence of castes and classes were the only variables that predicted private property in all of the datasets that were utilized.

This study attempts to expand on the list of common customs employed to cope with childlessness in a marriage. Authors specifically examine the relationship between the presence of customs that help cope with childlessness and the severity of punishment for adultery. Results indicate a significant relationship between these two variables.

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.

Sampling 62 societies from the HRAF database (32 bilateral, 21 patrilineal, 6 matrilineal, and 3 double-unilineal societies)the author asks whether divorce rates can be predicted by the descent systems or the network of marriage affiliations. Findings do not support the theory that divorce rates will be predicted by descent (patrilineal vs bilateral) - but they are more consistent with the idea that conjunctive affiliations are predictive of low divorce rates in bilateral societies. In lineal societies the levirate is used as an indicator.
