The authors examine degree of intensiveness (kin-relatedness) among foraging and agropastoralist societies, predicting that hunter-gatherers will pursue more extensive kinship networks in order to maximize residential options in the case of unpredictability or uneven geographic distribution of food resources. Support is found for the hypothesis, and it is suggested that while extensive fission-fusion dynamics are beneficial in foraging systems, the increase in cooperation in large-scale agricultural settlements is aided by norms which encourage kin marriage and relatedness.

The present research examines the residence patterns of 34 hunter-gatherer societies and 34 lowland South American horticulturalist societies using census data. Contrary to the traditional view of patrilocal postmarital residence being prevalent, the present findings suggest more multilocality in residence patterns for hunter-gatherer and horticulturalist societies. The author concludes that hunter-gatherers are slightly patrilocal and horticulturalists slightly matrilocal.

This article focuses on parents’ investment of material resources at the time of their child’s marriage. Two patterns emerge from the data: wealth is generally transferred from the groom’s family to the bride’s and from the couple’s parents to the bride and groom. Social and ecological factors are also examined. Multiple regression analysis shows that paternal confidence level, societal polygyny rate, and level of pathogen stress can affect the aforementioned wealth transfer patterns.

Researchers examine marriage patterns of 186 societies from the Standard Cross-Cultural Sample (SCCS). The eleven predictor variables are pathogen stress, arranged female marriages, population density, father roles during infancy, temperature, social stratification, wealth inequality, internal warfare, assault frequency, female agricultural contribution, and sex ratio. The two outcome variables measuring polygyny are cultural rules constraining polygyny and the percentage of married men who are polygynous. Controlling on phylogeny using a global supertree of the languages, analysis of marriage patterns reveals that assault frequency and pathogen stress are the strongest predictors of polygyny. These findings offer additional support for the theories of harem-defense polygyny and male genetic quality.

This study is a comprehensive analysis of female and male genital mutilation/cutting (FGM/C and MGM/C) practices, including their history and socio-ecological correlates, using a phylogenetic cross-cultural framework. It employed two global ethnographic samples, the Ethnographic Atlas (EA) and the Standard Cross-Cultural Sample (SCCS), and two subsets of the phylogeny (supertree) of human populations based on genetic and linguistic data, to investigate the variables that may have led to the introduction of these practices, and to determine where and when they may have originated. The study suggests that MGM/C probably originated in polygynous societies with separate residence for co-wives, supporting a mate-guarding function, and that FGM/C likely originated subsequently and almost exclusively in societies already practicing MGM/C, where it may have become a signal of chastity. Both practices are believed to have originated multiple times, some as early as in the mid-Holocene (5,000–7,000 years ago). The study posits that GM/C co-evolves with and may help maintain fundamental social structures and that the high fitness costs of FGM/C are offset by social benefits, such as enhanced marriageability and social capital.

This article seeks to examine the distribution and frequency of bride-theft. Tylor's (1889) findings between various forms of marriage by capture and certain other social instituions are confirmed.

This study tests the hypothesis that humans tend to transmit wealth to male heirs where polygyny is possible. The results support this hypothesis.

This study examines bridewealth and brideservice using a theory that emphasizes the role of parental selection in arranged marriages. Bridewealth and brideprice are postulated to enable parents of the bride to screen their future son-in-law. Information presented is supported by a literature review; no formal testing. See Apostolou, M. (2007) for more analyses.

This article uses factor analysis to identify the key variables underlying the many cross-cultural associations reported by Textor (1967). Twelve factors are identified.

An early cross-cultural study that sought to establish correlations between "stages" of economic culture and a variety of different social and political institutions, such as form of government and justice, marriage and kinship, and behaviors during warfare.
