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

This article reviews interpretations of an established relationship between matrilocal residence, sedentarism, and local endogamy. The author offers an interpretation focused on succession of leadership in matrilocal societies: exogamy will be associated with achieved status while endogamy will be associated with a matrilineal succession of authority.

Using the compiled database "Seshat: Global History Databank," researchers sampled 30 societies from 10 distinct regions of the world, testing 51 variables that were condensed into 9 "complex characteristic" variables. Researchers tested for correlates in how societies evolve structurally. Utilizing principal component analysis it was demonstrated that the complex characteristic variables were strongly associated, leading to theorization of structural and social evolution predictability.

How did moralizing religions rise, and what have they caused? The authors test the Big Gods theory, which suggests moralizing religions as a predictor of large-scale complex societies. In addition, they propose their hypothesis, which indicates that warfare, animal husbandry, and agricultural productivity have a role in producing moralizing religions. The results show no significant support for the Big Gods hypothesis. However, they support intergroup warfare, particularly military technologies and cavalry, as an important predictor of social complexity and moralizing religions. In addition, pastoralism has a moderate effect as a predictor for the rise of moralizing religions.

What have been the causes and consequences of technological evolution in world history? In particular, what caused an increase widespread of military technologies, details of which are comparatively well preserved and which are often seen as drivers of broad socio-cultural processes? This study analyzes competing theories of military technological change by examining whether population proportion, connectivity among societies, major technological innovations, and state-level characteristics influenced the development and diffusion of military technologies over approximately 10,000 years of pre-industrial history. Using data from the Seshat: Global History Databank, the authors analyzed patterns of military technological evolution across a worldwide sample of pre-industrial societies with dynamic regression models that accounted for temporal and spatial processes. What was found was that global population size, connectivity through networks of information exchange, and enabling innovations such as iron metallurgy and horse riding were significant predictors of advances in military technology. In contrast, state-level characteristics—including population size, territorial extent, and administrative sophistication—showed little evidence of influencing technological development. These results suggest that military technological evolution was driven primarily by large-scale demographic and intersocietal processes rather than internal political organization, providing new evidence for understanding the long-term evolution of technology and increasing social complexity.

The authors implement an anthropological approach to explore the evolutionary and cultural explanations of modern obesity. Three widely accepted facts are considered: (1) gender dimorphism (women having higher levels of fat), (2) increase of obesity with modernization, and (3) a positive association between obesity and socioeconomic status. Using theory, cross-cultural research, and case studies, the authors hypothesize how obesity may have been selected for (or not selected against) in an evolutionary context considering both biological and social factors.

In the present study, Peregrine tests two perspectives regarding social resilience to climate-related disasters: 1) that societies with more inclusive and participatory political structures (corporate political strategies) are more resilient to climate-related disasters, and 2) that societies with tighter adherence to social norms are more resilient to climate-related disasters. Results support the notion that societies with greater political participation are more socially resilient to catastrophic climate-related disasters. Because these results are justifiably generalizable across multiple historical and cultural contexts, Peregrine's findings are a useful contribution to aid in disaster response policy decision making.

This article discusses the reasons behind advances in craft specialization particularly why there is a relationship between advances in craft specialization and the emergence of powerful elites. Hypothesis tests focused on political centralization.

This article tests for universal patterns in cultural evolution by Guttman scaling on two different worldwide samples of archaeological traditions and on well-known archaeological sequences. The evidence is generally consistent with universal evolutionary sequences.

This study examines relationships between subsistence type, population size, and sedentarism. Hunting, gathering, fishing, and herding societies tend to be smaller than horticultural and agricultural societies. Horticulture, agriculture, and fishing societies tend to be more sedentary.
