The present research examines the consumption, treatment, and disposal of the human placenta in a sample of 179 societies. The findings reveal differences between placental mammals and humans as maternal placentophagy, the consumption of the placenta, is rare. Treatment and disposal of the placenta is variable but ubiquitous cross-culturally.

Using a sample of 60 societies from eHRAF, this study explores the cross-cultural commonalities and differences in human-pet dynamics. The authors focus on understanding the range of functions of pets and the positive or negative treatment of pets. In addition, they test whether human investment in pets is a significant challenge of evolutionary theory. First, the results support that there are distinct functions of pets, challenging the common view of contemporary function of pets as emotional surrogates. Secondly, the data collected show an ambivalent treatment of pets across cultures, including small-scale societies. Finally, the research does not support the idea that human investment in pets sacrifices their reproductive success.

This article investigates relationships between socialization practices, group values, and cultural complexity. Analysis suggests that child-rearing variables and group cohesion in value orientation contribute significantly and independently to cultural complexity.

This chapter examines infant carrying practices across cultures. The author suggests that infant carrying practices are affected by both climate and history. Findings indicate regional patterns in infant carrying practices and in the borrowing of infant carrying practices within regions. Results support the hypothesis.

This article tests hypotheses put forth by Murdock that female contribution to subsistence is associated with matrilocal residence.
