黑猩猩很少分享野生植物食物，但在从事狩猎的黑猩猩群体中，肉经常被用作培育联盟和社会纽带的“社会工具”。在这里，我们报告了唯一有记录的无血缘关系的野生黑猩猩定期分享植物性食物的例子，以及这些分享行为发生的背景。从直接观察来看，Bossou（西非几内亚共和国）的成年黑猩猩很少转移野生植物食物。相比之下，他们分享种植的植物性食物的频率要高得多（59次食物分享事件中有58次）。分享主要是由成年雄性允许繁殖周期的雌性拿走它们拥有的食物。我们提出，“以食物换性和打扮”以及“炫耀”策略的假设合理地解释了观察到的分享行为。不断变化的人类主导的景观给黑猩猩带来了新的挑战，我们的观察表明，劫掠农作物为Bossou的成年雄性黑猩猩提供了非常理想的食品，这些食品可以兑换成其他货币。
The sharing of wild plant foods is infrequent in chimpanzees, but in chimpanzee communities that engage in hunting, meat is frequently used as a ‘social tool’ for nurturing alliances and social bonds. Here we report the only recorded example of regular sharing of plant foods by unrelated, non-provisioned wild chimpanzees, and the contexts in which these sharing behaviours occur. From direct observations, adult chimpanzees at Bossou (Republic of Guinea, West Africa) very rarely transferred wild plant foods. In contrast, they shared cultivated plant foods much more frequently (58 out of 59 food sharing events). Sharing primarily consists of adult males allowing reproductively cycling females to take food that they possess. We propose that hypotheses focussing on ‘food-for-sex and -grooming’ and ‘showing-off’ strategies plausibly account for observed sharing behaviours. A changing human-dominated landscape presents chimpanzees with fresh challenges, and our observations suggest that crop-raiding provides adult male chimpanzees at Bossou with highly desirable food commodities that may be traded for other currencies.
