The authors do the field of cultural evolution a service by exploring the role of non-social cognition in human cumulative technological culture, truly neglected in comparison with socio-cognitive abilities frequently assumed to be the primary drivers. Some specifics of their delineation of the critical factors are problematic, however. I highlight recent chimpanzee–human comparative findings that should help refine such analyses.

细化我们对“房间里的大象”的理解

作者通过探索非社会认知在人类累积技术文化中的作用来为文化进化领域提供服务，与经常被认为是主要驱动力的社会认知能力相比，这种认知确实被忽视了。然而，他们对关键因素的描述的一些细节是有问题的。我强调了最近的黑猩猩与人类的比较发现，这些发现应该有助于完善此类分析。
