The New Caledonian crow may be the only non-primate species exhibiting cumulative technological culture. Its foraging tools show clear signs of diversification and progressive refinement, and it seems likely that at least some tool-related information is passed across generations via social learning. Here, we explain how these remarkable birds can help us uncover the basic biological processes driving technological progress.
新喀鸦可能是唯一表现出累积技术文化的非灵长类物种。它的觅食工具显示出明显的多样化和渐进式的精细化迹象，而且至少有一些与工具相关的信息似乎是通过社会学习在代际间传递的。在这里，我们解释这些非凡的鸟类如何帮助我们揭示推动技术进步的基本生物学过程。
