我们探索了蜜蜂在一项任务中的行为灵活性，这项任务需要将一个小球运送到一个确定的位置以获得奖励。蜜蜂被预先训练知道球的正确位置。随后，为了获得奖励，蜜蜂必须将一个被移动的球移动到指定的位置。蜜蜂观察演示的技术，从一个活的或模型演示学习任务更有效地比蜜蜂观察“鬼”示范（球通过磁铁移动）或没有示范。观察者没有模仿演示者长距离移动球，而是更有效地解决了任务，使用最接近目标的球，即使它的颜色与之前观察到的不同。这种前所未有的认知灵活性表明，如果相关的生态压力出现，那些生活方式需要高级学习能力的物种可能会相对迅速地出现全新的行为。
We explored bees' behavioral flexibility in a task that required transporting a small ball to a defined location to gain a reward. Bees were pretrained to know the correct location of the ball. Subsequently, to obtain a reward, bees had to move a displaced ball to the defined location. Bees that observed demonstration of the technique from a live or model demonstrator learned the task more efficiently than did bees observing a "ghost" demonstration (ball moved via magnet) or without demonstration. Instead of copying demonstrators moving balls over long distances, observers solved the task more efficiently, using the ball positioned closest to the target, even if it was of a different color than the one previously observed. Such unprecedented cognitive flexibility hints that entirely novel behaviors could emerge relatively swiftly in species whose lifestyle demands advanced learning abilities, should relevant ecological pressures arise.
