In some gathering and hunting communities, food brought into a camp is shared beyond the person who obtained it. Sharing can help when one day’s hunt succeeds and another does not, while also expressing expectations about generosity and belonging. Anthropologists study the social rules around who gives, receives and decides.
Describing a group as egalitarian requires more than seeing one shared meal. Differences in age, experience or influence may still matter, and practices change over time. Ask how decisions are made as well as how food moves.
