The wild chimpanzees in Gombe National Park, Tanzania, fish for termites with flexible tools that they make out of vegetation, inserting them into the termite mound and then extracting and eating the termites that cling to the tool. Tools may be used in different ways by different chimpanzee communities according to the local chimpanzee culture. Here we describe the results of a four-year longitudinal field study in which we investigated how this cultural behaviour is learned by the community's offspring. We find that there are distinct sex-based differences, akin to those found in human children, in the way in which young chimpanzees develop their termite-fishing skills.
坦桑尼亚贡贝国家公园的野生黑猩猩会用它们用植物制作的灵活工具来钓白蚁，将工具插入蚁丘，然后取出并吃掉附着在工具上的白蚁。根据当地黑猩猩文化，不同的黑猩猩群体可能会以不同方式使用工具。在此，我们描述了一项为期四年的纵向实地研究结果，在该研究中，我们调查了社群中的后代是如何习得这种文化行为的。我们发现，幼年黑猩猩发展白蚁捕捉技能的方式存在明显的基于性别的差异，这与人类儿童的情况类似。
