It has long been claimed that certain configurations of facial movements are universally recognized as emotional expressions because they evolved to signal emotional information in situations that posed fitness challenges for our hunting and gathering hominin ancestors. Experiments from the last decade have...

These partici- pants are part of the B200–300 traditionally living Hadza, who are one of the last remaining hunting and gathering communities in the world. The Hadza live in small mobile camps with fluid membership, usually comprising a core group of B30 people, and target native wild foods...

Instead of relying on anonymous, economic games to measure cooperation, we ask participants to rank their current campmates by who is the most generous and best at hunting or gathering, as well as who they would most like to live with. We then compare their preference for more generous camp...
(Table1). BaYaka participants listed 17 subsistence tasks (see Table S1in the ESM for raw free-list responses) which we categorized into larger subsistence domains (e.g., net hunting → Hunting and trapping; Table1). For each of the nominated subsistence domains, participants were also asked...
Past research indicates Americans infer hunting and gathering ability from others' faces, but the accuracy of these perceptions remains unknown. In three studies, we test whether Americans can accurately perceive foraging ability from faces. We used three datasets from two traditional subsistence ...
Among hunter-gatherers, the sharing of male and female foods is often assumed to result in virtually the same diet for males and females. Although food sharing is widespread among the hunting and gathering Hadza of Tanzania, women were observed eating significantly more tubers than men. This ...
The Hadza are one of the world's few remaining hunting and gathering communities, living in small mobile camps around the shores of Lake Eyasi in Northern Tanzania8. As such, they represent a unique opportunity to approximate the microbiota-host configura- tions arising from a foraging ...
