Abstract Intense coastal resource exploitation is an important topic, and large South African west coast shell middens (megamiddens) are an example of it. Parkington et al. (2020) attempt to explain them, but they fail dismally in doing so by using biased observations and championing field processing and transport as single explanations. Here, their flawed proposal is contrasted with much ignored published data, revealing a unique and dynamic interplay of factors resulting from settlement and foraging decisions.

开普西海岸贝类加工、人口增加和狩猎采集资源集约化

摘要 沿海资源的密集开发是一个重要课题，南非西海岸大型贝壳沼泽（megamiddens）就是一个例子。帕金顿等人。(2020) 试图解释它们，但他们通过使用有偏见的观察并支持将现场处理和运输作为单一解释而失败了。在这里，他们有缺陷的提议与被忽视的公开数据形成鲜明对比，揭示了由定居和觅食决定导致的独特而动态的相互作用。
