A kind man benefits himself – but how? Evolutionary models of human food sharing

Behavioral and Brain Sciences 27 (4):563-564 (2004)

Abstract

Can evolutionary models explain food sharing in traditional human societies? Gurven's analysis cannot rule out any of the models (kin selection, reciprocal altruism, tolerated scrounging, costly signaling, or by-product mutualism), and quantitative partitioning of relative importance is not feasible. For now, the hypotheses seem like the proverbial blind men examining the elephant: each was partly in the right, and all were in the wrong!
