尽管分享食物是黑猩猩生活的一个习惯，但不相关的成年黑猩猩之间分享植物性食物的情况却很少见。对这种行为的观察通常被解释为一个过程的结果，通过这个过程，原本无法获得食物的个体设法获得营养益处。在这里，我们提出的行为细节和声学分析观察无关的成年野生黑猩猩之间的食物共享，我们建议不能用传统的营养为基础的模型来解释。相反，我们提出，交换是唯一可以理解的社会重要事件，我们引用了两个进一步的观察，在同一人口支持这一建议。(c)2005 Wiley-Liss，Inc.
Although food sharing is a habitual aspect of chimpanzee (Pan troglodytes) life, sharing of plant foods between unrelated adults is rare. Observations of such behavior have typically been interpreted as the outcome of a process by which individuals that are otherwise unable to gain access to the food manage to obtain a nutritional benefit. Here we present behavioral details and an acoustic analysis regarding an observation of food sharing between unrelated adult wild chimpanzees that we suggest cannot be explained using traditional nutrition-based models. Instead we propose that the exchange is only understandable as a socially important event, and we cite two further observations in the same population that support this suggestion.
