What promised to be a refreshing addition to cumulative cultural evolution, by moving the focus from cultural transmission to technological innovation, falls flat through a lack of thoroughness, explanatory power, and data. A comprehensive theory of cumulative cultural change must carefully integrate all existing evidence in a cohesive multi-level account. We argue that the manuscript fails to do so convincingly.

范围和证据有限的理论

通过将重点从文化传播转移到技术创新，有望为累积的文化进化带来令人耳目一新的补充，但由于缺乏彻底性、解释力和数据而落空。累积文化变革的综合理论必须仔细地将所有现有证据整合到一个有凝聚力的多层次帐户中。我们认为手稿未能令人信服地做到这一点。
