  1. All models include random effects for Individual and Society. Age Early Childhood (between 3 and 6 years of age, early juveniles for the Mikea dataset—reference category), Middle Childhood (between 7 and 12 years of age, late juveniles for the Mikea dataset), Adolescence (between 13 and 18 years of age, young adults for the Mikea dataset). Gender: Girls (reference category) and Boys. Prop Non-Foraged Food proportion of diet which was domesticated foods and foods purchased and/or traded. Gendered Division of Food Production Labour Standardized to between − 2, women do all the food production labour and 2, men do all the food production labour. NPP Net Primary Productivity in gC/m2/year. Annual Precipitation In mm. Annual Mean Temperature In °C. Dangerous Mammal Density Low/High. Water Quality/Quantity Four-point scale.
