Using a sample of 313 societies classified within 24 language phyla, authors put forward a statistical model based on climate data [specifically focused on the 10°C (50°F) winter temperature isotherm] to explain why dispersion of preindustrial language phyla is remarkably homogeneous even despite heterogeneous geographical dispersion of sampled preindustrial cultural groups. They suggest that temperature has been a barrier to migration.

The authors put forward a theoretical model called "personality integration of culture." At the heart of the model is the idea that psychological processes may help explain why certain aspects of culture are related to other aspects. To test this model they focus on theories and therapies regarding illness and they use psychoanalytic ideas on positive and negative fixation to suggest how differences in child-rearing customs may account for different ideas about the causes of illness. The strongest results relate to socialization anxiety in a particular area of socialization (e.g., oral, dependency, and aggression) amd respective causes of illness. Results regarding negative fixation are generally supported, whereas positive fixation is not.

This paper seeks to identify how different practices of food sharing are related to one another, and the degree to which societies in North and South America may share practices with one another. The authors attempt this by using ethnographic literature to break sharing activities down into their constituent, multi-stage parts, and then comparing the prevalence of these parts and their relationships to one another. The study finds that the presence or absence of a distributor in a sharing activity, and who that distributor is, has a significant effect on how sharing is carried out. On the other hand, linguistic relationships between groups seem to have little impact on their sharing practices, and geographic proximity between groups only seems to have a significant effect on sharing practices in North America.

This book is a comprehensive analysis of many aspects of social structure including family, clan, community, kinship terminology, social organization, regulation of sex, incest taboos, and sexual choice.

This paper suggests a tentative analysis of continuous female sexual receptivity based on a random sample of mammals and birds. It is suggested that humans developed continuous female sexual receptivity because humans have the unusual combination of long infant dependency, group living, and male-female bonding.

The researchers utilize a GIS approach in order to examine the relationship between global linguistic distribution and various cultural and environmental factors. The resulting positive association between political complexity and both latitude and language range leads the researchers to propose that large, politically complex entities exert a homogenizing pressure on language. However, the causal link may also be in the other direction, with possession of common language facilitating the creation of more complex political institutions.
