In this study, the author closely examines the educational outcomes of Christian missions in sub-Saharan African societies. He shows that there was local demand for formal education, but theorizes that this demand decreased in polygamous societies as Christian missionaries required monogamy for entry. His results show areas that experienced this struggle over polygamy are associated with worse educational outcomes than those that did not.

This study examines pairwise differences between similar cultures in order to minimize cultural variation within the SCCS and reveal possible correlates of cultural complexity. Results suggest that one measure of complexity (government above the community level) is significantly associated with several other variables.

This paper examines Murdock's (1949) definitions and data pertaining to the universal functions of the nuclear family. The author asserts that Murdocks definitions and data are faulty and finds that Murdock's claims regarding the universality of nuclear families are unsupported.

Lowes and Nunn test the theory that the transatlantic and Indian Ocean slave trades of the thirteenth to nineteenth centuries prompted a shift towards matrilineal kinship systems throughout sub-Saharan Africa. Controlling for ecological variables commonly thought to affect kinship structure (including ruggedness of terrain, suitability for agriculture, etc.), the authors find a significant correlation between the number of people enslaved from a given ethnic group, and the tendency of that group towards a matrilineal kinship system. Polygyny was also identified as a statistically significant characteristic of communities most impacted by the slave trade.

The present study examines 70 Austronesian cultures to test whether political hierarchy, population size, and social inequality have been influential in the conversion of populations to Christianity. Cultural isolation and year of missionary arrival are control variables. Using phylogenetic generalized least squares (PGLS), the researchers test the effect of the three predictor variables on conversion to Christianity and also conduct a multivariate analysis with all variables. The results do not offer support for what is expected by top-down and bottom-up theories of conversion but instead for the general dynamics of cultural transmission.

The authors of this study examine the relationships between historical exposure to Islamic kingdoms and current economic, medical, and educational development in Africa. They predict that ethnic groups that were previously ruled by Islamic states or chiefdoms will have worse outcomes today, theorizing that these worse outcomes would be not as a result of an inherent characteristic of Islam or Islamic kingdoms themselves but rather decreased investment by colonial states or missions. Their results lend some support to their hypotheses, and particularly to the predictions that Christian missions and colonial states would not be able to penetrate areas under Islamic influence as easily as other regions.

The 'obstetrical dilemma' postulates that human females evolved a pelvis shape that was a compromise between the needs of bipedal locomotion and the need for a wider pelvic opening. The implication is that the female pelvis should be similar across the world. Researchers examine the size and shape of the birth canal of female individuals in the Goldman and Human Origin datasets. Contrary to the 'obstetrical dilemma,' the findings reveal that there is indeed significant geographical variation in size and shape of the female birth canal. Neutral evolutionary processes, particularly genetic drift, were suggested to be influential in female canal shape whereas the predicted effects of climate on canal diversity were only minimal.
