This study investigates the time-hardened question of whether alcohol had any role in the evolution of complex societies, aka the “drunk’ hypothesis. Although indigenous alcoholic beverages are found in about 50% of societies around the world largely excluding native North America and Oceania, low-alcohol fermented drinks have been known to aid in social cohesion, maintaining political ties (through feasting), and rituals. While it is clear alcohol is not a direct indicator of social complexity, when controlling for agriculture and other major factors, the relationship between the two is significant.

This article examines a hypothesis that associates alcoholism with the structure and quality of social norms related to drinking. Analysis yields little support for this hypothesis, but the amount of alcohol consumed by members of the society emerges as an important predictive variable. A new theory of alcoholism that takes this variable into account is discussed.

Using t-test, generalized linear models (GLMs) and Bayesian regression models in a sample of 1188 pre-industrial societies, this study explores the research question: Why have foraging, horticulture, and pastoralism persisted into the 20th and 21st century? The authors test the marginal hypothesis and the oasis hypothesis of agricultural intensification. The first hypothesis suggests that foragers persisted because foragers predominantly inhabited marginal habitats that were typically unsuitable for agricultural purposes. The second hypothesis suggests that intensive agriculture emerged in regions characterized by limited biodiversity and a dependable water supply not reliant on local rainfall. In addition, the authors test whether specific kinds of biodiversity (elephants, malaria, and tsetse flies) correlate with agricultural intensification in African societies. The results support the marginal and oasis hypotheses, but only marginally support the African hypothesis, since only tsetse fly has a significant negative correlation to agricultural intensification.

This article investigates the adoption of agriculture. The author tests three possible predictors: environmental richness, population density, and division of labor by gender. Minimal support is found for these variables, and the author proposes two alternative explanations, based on diminishing returns in food production and balancing the food portfolio.

This study examines a hypothesis that ceremonial drinking is negatively associated with heavy secular drinking. Empirical analysis does not support this association, and the author proposes an alternative theory of alcohol consumption and the problem of evil. Hypotheses relating alcohol consumption to menstrual taboos and the uses of blood in society are supported.

This article focuses on the effect of environmental extremes and unpredictability on human behavior and reproductive strategies. Significant correlations were found between environmental extremes and unpredictability and several variables, including mobility, subsistence mode, and degree of polygyny.
