尽管在许多传统社会中已经观察到食物共享，但我们仍然没有深入了解各种生态条件如何在谁给予和谁接受特定资源方面产生变化。为了更好地了解行为生态学的食物分享，我们目前收集的数据与Hiwi的委内瑞拉，并专注于两个问题：（一）如何特性的食物资源和收购者确定有多少是转移给别人？(b)核心家庭A和B的特征如何影响A和B之间的转移量？我们使用路径模型，试图梳理除了生物亲缘关系，家庭之间的地理接近，家庭规模，和数量的家庭B给家庭A的预期数量，家庭A给家庭B的相对贡献。互惠利他主义被证明是一个重要的环节链的因素，但不是在达特的形式常见的理论治疗互惠。
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.
