New Caledonian (NC) crow populations have developed complex tools that show suggestive evidence of cumulative change. These tool designs, therefore, appear to be the product of cumulative technological culture (CTC). We suggest that tool-using NC crows offer highly useful data for current debates over the necessary and sufficient conditions for the emergence of CTC.
新喀里多尼亚（NC）乌鸦种群已经发展出复杂的工具，这些工具显示出累积变化的有力证据。因此，这些工具设计似乎是累积技术文化（CTC）的产物。我们认为，使用工具的 NC 乌鸦为当前关于 CTC 出现的必要和充分条件的争论提供了非常有用的数据。
