核心家庭之间的亲属关系的存在是家庭间共享的最强有力的预测，在一个土著，主要是多尔干人的食物共享网络在北方俄罗斯。配对家庭中猎人的总数等属性也是核心家庭之间分享差异的主要原因。在成本效益模型方面，调查了伙伴家庭中猎人人数的差异，以及家庭的接近程度和生产者/消费者比率。在84个家庭中，有26个家庭参与了互惠膳食共享。在这个子集中的家庭之间的互惠共享膳食的频率与平均家庭相关性呈正相关。通过集群的合作的演变可能会阐明在这个最亲密的食物共享水平上亲属关系和互惠之间的关系。
The presence of a kinship link between nuclear families is the strongest predictor of interhousehold sharing in an indigenous, predominantly Dolgan food-sharing network in northern Russia. Attributes such as the summed number of hunters in paired households also account for much of the variation in sharing between nuclear families. Differences in the number of hunters in partner households, as well as proximity and producer/consumer ratios of households, were investigated with regard to cost-benefit models. The subset of households involved in reciprocal meal sharing is 26 of 84 household host-guest pairs. The frequency of reciprocal meal sharing between families in this subset is positively correlated with average household relatedness. The evolution of cooperation through clustering may illuminate the relationship between kinship and reciprocity at this most intimate level of food sharing.
