“Economic man” in cross-cultural perspective: Behavioral experiments in 15 small-scale societies
A cross-cultural study of behavior in ultimatum, public goods, and dictator games in a range of small-scale societies exhibiting a wide variety of economic and cultural conditions found the canonical model – based on self-interest – fails in all of the societies studied.
Costly Punishment Across Human Societies
Experimental results from 15 diverse populations show that all populations demonstrate some willingness to administer costly punishment as unequal behavior increases, and the magnitude of this punishment varies substantially across populations, and costly punishment positively covaries with altruistic behavior across populations.

In "The Hadza", Frank Marlowe provides a quantitative ethnography of one of the last remaining societies of hunter-gatherers in the world. The Hadza, who inhabit an area of East Africa near the…
Gut microbiome of the Hadza hunter-gatherers
It is shown that the Hadza have higher levels of microbial richness and biodiversity than Italian urban controls, and enrichment in Prevotella, Treponema and unclassified Bacteroidetes, as well as a peculiar arrangement of Clostridiales taxa, may enhance the hadza’s ability to digest and extract valuable nutrition from fibrous plant foods.
Markets, Religion, Community Size, and the Evolution of Fairness and Punishment
Fairness is measured in thousands of individuals from 15 contemporary, small-scale societies to gain an understanding of the evolution of trustworthy exchange among human societies and shows that market integration positively covaries with fairness while community size positively covary with punishment.
Hunter‐gatherers and human evolution

The ethnographic record of foragers provides the only direct observations of human behavior in the absence of agriculture, and as such is invaluable for testing hypotheses about human behavioral evolution.
Co-Residence Patterns in Hunter-Gatherer Societies Show Unique Human Social Structure
It is found that hunter-gatherers display a unique social structure where either sex may disperse or remain in their natal group, adult brothers and sisters often co-reside, and most individuals in residential groups are genetically unrelated, which suggests large social networks may help to explain why humans evolved capacities for social learning.
Social Networks and Cooperation in Hunter-Gatherers
The social networks of the Hadza, a population of hunter-gatherers in Tanzania, are characterized, showing that Hadza networks have important properties also seen in modernized social networks, including a skewed degree distribution, degree assortativity, transitivity, reciprocity, geographic decay and homophily.
