This paper examines relationships among mode of production, sedentarism, and population size. Generally, agricultural societies were found to be sedentary and have larger populations, while migratory societies (such as herders or hunters) had smaller population size.

This study examines the relationship between personality traits and subsistence type in mixed farming and pastoralists societies. Findings suggest that differences in child socialization do not significantly predict personality differences in mixed farming and pastoralist societies as much as one would expect. Adult experiences should be considered as better predictors of personality traits.

This article proposes that ground plans may be used as a criterion for determining the relative permanence of settlement patterns in archaelogical societies. Results suggest that impermanent settlements and small community size are significantly associated with circular ground plans and that permanent settlements with larger community sizes are significantly associated with rectangular ground plans.

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.

Dopamine receptor D4 (DRD4) exhibits the largest number of polymorphisms of any dopamine receptor yet identified, and variation in DRD4 has been linked to variation in traits such as novelty-seeking and attention deficit/hyperactivity disorder. DRD4 also exhibits large variation between populations. Here, the authors test the hypothesis that natural selection acting on DRD4 may account for variation in between-population migratory patterns, using genetic and historical data from 39 populations.
