The knapping experiments with Kanzi, a bonobo, are among the most insightful experiments into Oldowan technology ever undertaken. Comparison of his artifacts against archeological material, however, indicated he did not produce Oldowan lithic attributes precisely, prompting suggestions that this indicated cognitive or biomechanical impediments. The literature describing the learning environment provided to Kanzi, we suggest, indicates alternative factors. Based on consideration of wild chimpanzee learning environments, and experiments with modern knappers that have looked at learning environment, we contend that Kanzi's performance was impeded by an impoverished learning environment compared to those experienced by novice Oldowan knappers. Such issues are precisely those that might be tested via a repeat study, but in this case, practical and ethical constraints likely impede this possibility. We propose experiments that may be relevant to drawing conclusions from Kanzi's experiments that may not need to use non‐human primates, thus bypassing some of these issues.

低估了坎兹？根据最近的人类石头工具复制来探索Kanzi-Oldowan比较。

用Kan黑猩猩Kanzi进行的敲打实验是对Oldowan技术进行的最有见地的实验之一。然而，他的文物与考古材料的比较表明，他没有精确地产生奥尔多万石器时代的属性，从而提示这表明存在认知或生物力学障碍。我们建议，描述提供给Kanzi的学习环境的文献指出了其他因素。基于对野生黑猩猩学习环境的考虑，以及针对学习环境的现代敲击者的实验，我们认为，与新手Oldowan敲击者所经历的学习环境相比，Kanzi的表现受到贫困学习环境的阻碍。这些问题正是可以通过重复研究进行测试的问题，但在这种情况下，实践和道德约束可能会阻止这种可能性。我们提出的实验可能与从Kanzi的实验得出结论有关，这些实验可能不需要使用非人类的灵长类动物，从而绕开了其中一些问题。
