摘要
Although food sharing has been observed in many traditional societies, we still do not have a deep understanding of how various ecological conditions produce variation in who gives and who receives specific resources. To understand better the behavioral ecology of food sharing we present data collected with the Hiwi of Venezuela and focus on two questions: (a) How do characteristics of food resources and acquirers determine how much is transfered to others? (b) How do characteristics of nuclear families A and B influence how much is transferred between A and B? We use path modeling in an attempt to tease apart the relative contribution of biological kinship, geographical proximity between households, family size, and quantities family B gave to family A on the expected quantities that family A gives to family B. Reciprocal altruism is shown to be an important link in the chain of factors, but not in the tit-for-tat form common in theoretical treatments of reciprocity.
