人类以特殊的方式与非亲属合作，但这些合作技能的进化基础仍不清楚。我们向黑猩猩提出了协作问题，它们必须决定何时招募合作伙伴以及招募哪个潜在合作伙伴。在最初的研究中，只有当解决问题需要协作时，个人才会招募合作者。在第二项研究中，个人根据前一天与每个人的经验，招募了两个合作伙伴中效率较高的一个。因此，识别何时需要协作并确定谁是最佳协作伙伴是黑猩猩和人类共有的技能，因此在人类进化出自己复杂的协作形式之前，这些技能可能已经存在于它们的共同祖先中。
Humans collaborate with non-kin in special ways, but the evolutionary foundations of these collaborative skills remain unclear. We presented chimpanzees with collaboration problems in which they had to decide when to recruit a partner and which potential partner to recruit. In an initial study, individuals recruited a collaborator only when solving the problem required collaboration. In a second study, individuals recruited the more effective of two partners on the basis of their experience with each of them on a previous day. Therefore, recognizing when collaboration is necessary and determining who is the best collaborative partner are skills shared by both chimpanzees and humans, so such skills may have been present in their common ancestor before humans evolved their own complex forms of collaboration.
