文化是指在社会中习得并随着时间的推移在人群中持续存在的行为。越来越多的证据表明，动物文化可以像人类文化一样，具有累积性：其特点是在先前的创新基础上不断进行创新。然而，人类累积文化涉及的行为非常复杂，超出了任何个人在其一生中独立发现的能力。据我们所知，迄今为止还没有研究在无脊椎动物中证明这种现象。在这里，我们展示了大黄蜂可以向训练有素的演示蜂学习打开一个新颖的两步拼图盒以获得食物奖励，即使它们无法独立这样做。实验者无法训练示范蜂执行无奖励的第一步，而不提供与此行为相关的临时奖励，该奖励在训练的后期阶段被删除。然而，三分之一天真的观察蜜蜂从这些示威者那里学会了打开两步盒子，但在迈出第一步后却没有得到任何奖励。这表明社会学习可能允许习得过于复杂的行为，而无法通过个人学习“重新创新”。此外，尽管暴露时间长达 24 天，天真的蜜蜂仍无法打开盒子。这一发现挑战了该领域的一个普遍观点：社会学习行为的能力无法通过个人试错来创新，这是人类独有的。
Culture refers to behaviours that are socially learned and persist within a population over time. Increasing evidence suggests that animal culture can, like human culture, be cumulative: characterized by sequential innovations that build on previous ones. However, human cumulative culture involves behaviours so complex that they lie beyond the capacity of any individual to independently discover during their lifetime, –. To our knowledge, no study has so far demonstrated this phenomenon in an invertebrate. Here we show that bumblebees can learn from trained demonstrator bees to open a novel two-step puzzle box to obtain food rewards, even though they fail to do so independently. Experimenters were unable to train demonstrator bees to perform the unrewarded first step without providing a temporary reward linked to this action, which was removed during later stages of training. However, a third of naive observer bees learned to open the two-step box from these demonstrators, without ever being rewarded after the first step. This suggests that social learning might permit the acquisition of behaviours too complex to ‘re-innovate’ through individual learning. Furthermore, naive bees failed to open the box despite extended exposure for up to 24 days. This finding challenges a common opinion in the field: that the capacity to socially learn behaviours that cannot be innovated through individual trial and error is unique to humans.
