Lullabies are often touted as universal to all human cultures, regardless of time and place. In order to test this axiom, this article examines all 186 societies in the Standard Cross-Cultural Sample, and codes them for the presence or absence of lullabies. The result ultimately hinges on the meaning of the word “lullaby”: when lullabies were defined as a strict and culturally conserved repertoire of songs sung to soothe infants, they were found to be neither a statistical nor even a “near” universal. However, when lullabies were defined as any type of singing used to soothe children, they were a near universal, with 96.8% of societies in the sample coded as having lullabies.

This study seeks to shed light on the practice of entomophagy (insect consumption) across human population and seeks to explain the variability in its practice. The author explore potential ecological predictors for insect consumption (climate, subsistence practices, other available food resources, dietary needs) as well as cultural predictors (social transmission, cultural norms, evolution, and shift). Ultimately, the author concludes that entomophagy may be a useful medium through which to examine the interaction between social learning, subsistence strategies, and modernization.

Do hunter-gatherers show concern for animals? Through an assessment of six types of concern across 28 hunter-gatherer groups, the author of this article finds that concern for animals is multifaceted. Feelings of overall indifference and callousness towards animals were exhibited in all hunter-gatherer groups; however, high levels of concern were shown towards animals regarded as pseudo-humans or pseudo-spirits.

The author tests various hypotheses regarding cross-cultural occurrence of geophagy, the eating of earth. Nearly 500 years of references to geophagy were compiled into the Database on Human Geophagy, which was then used to examine biological justifications for this little-understood behavior.

This article examines meat avoidance during pregnancy as an evolutionary adaptation. Data suggests that during pregnancy, meat avoidance is significantly more common cross-culturally than other types of food avoidance. The timing of meat avoidance, the presence of meat-borne pathogens, and sensory and ingestive changes in early pregnancy are also discussed.

Prevailing anthropological theory holds that social norms restricting the promiscuity of women tend to be more prevalent in pastoralist societies, where the long periods of unmonitored separation between spouses that often arise as a result of animal herding tends to result in stricter repression of female sexuality. This article explores the relationship between several societies' historical reliance on pastoralism and their attitudes towards four topics related to female promiscuity: abortion, female mobility, female promiscuity and female genital mutilation. The author finds all for topics to be significantly correlated with historical reliance on pastoralism.

While a growing body of research being conducted in Western societies suggests that both religious/spiritual (R/S) and so-called “pro-science” belief systems are correlated with better health and well-being, a widespread perception also exists that these two categories of belief systems are fundamentally incompatible. This article tests that perception. The authors finds that cross-culturally – and particularly outside of modern Western societies – it is largely incorrect. Rather, around the world individuals adhere to both R/S and pro-science belief systems at the same time, and often benefit from both of them.

This study, primarily a review on the evolution of the human diet, also includes a small study on the distribution of meat-eating and its relationship with climate and cultural factors, namely subsistence type. The authors find that societies with subsistence strategies that prioritize fishing, hunting, or pastoralism also tend to consume more animal products, whereas those that focus on agriculture have more plant-based diets. The authors argue that these small-scale societies have a healthier approach to diet than industrialized societies regardless of their subsistence type or meat consumption.

Textor summarizes cross-cultural findings on pregnancy and childbirth pertaining to cultural, environmental, psychological, and social phenomena.

Geophagy during pregnancy has been proposed to fulfill a number of adaptive functions, including relieving gastrointestinal distress, detoxification of the secondary compounds found in plant foods, and providing a supplementary source of minerals such as calcium. Using a sample of 60 African populations, the authors investigate geophagy during pregnancy in a cross-cultural perspective, emphasizing variation between dairying and non-dairying populations.
