This article examines direction of succession and inheritance as they relate to culture area and kinship system. Several hypotheses are presented and all are supported.

This paper examines diverging devolution—the transmission of property to both males and females—and its predictors and consequences. Particular attention is paid to kinship terminology and control of women’s marriage. Multiple hypotheses are supported.

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 chapter considers several forms of wealth transmission at marriage. The relationships between descent rules and incidence of bridewealth, dowry, and gift exchange are examined and several patterns emerge from empirical analysis.

This paper examines the behavior between close kin and affines of the opposite sex. The authors "point to certain differences between continental areas that are related to specific social factors, including the structure of descent groups and the nature of marriage arrangements."

This article discusses the relationship between plural marriage and women's position in the economy. Comparisons are made between this relationship in various locations and cultures. The article concludes that female farming is not sufficient as an explanation.

This study investigated the difference in rates of violence of precolonial states and stateless ethnic groups in postcolonial Africa. The author hypothesized ethnic groups of precolonial states (PCS) would experience more violence, (i.e. coup attempts and civil wars) than non-PCS groups. The author suggested that because of PCS countries’ inability to allow rival ethnic groups into power positions in addition to the extra power PCS groups gained under colonial rule may lead to more violence.

Genetic, linguistic, and geographic data can be used to explain the distribution of cultural units ("semes") and to understand the evolutionary mechanisms of culture. Three broad models of cultural transmission attempt to explain why cultures share semes: (1) Cultural diffusion, emphasizing horizontal transmission. (2) Local adaptation, where trail-and-error learning leads to the independent adoption of semes by different peoples living in similar environments. (3) Demic diffusion, which emphasizes vertical and frequency-dependent transmission. Authors test the explanatory power of each model using cultural, genetic, linguistic and geographic data from 36 African cultures.

The goal of the paper is to demonstrate how international slave trade spread the institution of slavery throughout Africa, resulting in long-term effects of the continent’s income and political centralization. The author first estimated the travel time to slave ports from each society in the Ethnographic Atlas to determine predicting factors for the adoption of slave trade in African societies. The author reported that societies with high exposure to slave capture in the past were more likely to have the custom of slavery and the custom of polygyny. The author further suggested that slavery institutions emerged in West Africa through local, politically centralized aristocratic systems while emerging in East Africa through the preservation of wealth within the nuclear family over generations.

This study explores ecological reasons that might explain why boys are mostly circumcised in tropical regions, particularly in Africa and the insular Pacific. The author postulates a long causal chain linking: 1) tropical climate to the growing of root and fruit crops; 2) the need to keep babies on mother's milk for as long as possible where the adult diet is lacking in protein; 3) a long post-partum sex taboo as a way to space births; 4) the practice of polygyny (and associated mother-child sleeping) in the face of a long sex taboo; 5) patrilocal residence; and 6) male initiation ceremonies which are believed to result from the combination of mother-child sleeping, the long poast-partum sex taboo and patrilocal residence.
