人类能够简单地观察因果之间的关系，然后产生一种新的行为模式，以重现同样的结果。然而，尚不清楚创造这种因果干预的能力是如何演变的。在这里，我们展示了，虽然24个月大的儿童在观察到相关性后可以产生有效的、新颖的动作，但制造工具的新喀里多尼亚乌鸦却不能。这些结果表明，复杂的工具行为不足以促进这种能力的进化，因果干预可以在认知和进化上与其他类型的因果理解相分离。
Humans are capable of simply observing a correlation between cause and effect, and then producing a novel behavioural pattern in order to recreate the same outcome. However, it is unclear how the ability to create such causal interventions evolved. Here, we show that while 24-month-old children can produce an effective, novel action after observing a correlation, tool-making New Caledonian crows cannot. These results suggest that complex tool behaviours are not sufficient for the evolution of this ability, and that causal interventions can be cognitively and evolutionarily disassociated from other types of causal understanding.
