这篇论文考察了巴拉圭东部AChE人一生中狩猎能力的变化。狩猎能力被分解为两个组成部分--发现猎物和遇到时被杀死的概率--并对重要的猎物物种进行了分析。结果支持这一论点，即技能获得是人类觅食生态位的一个重要方面，狩猎结果变量在生命的后期达到惊人的峰值，显著晚于体力峰值。这项研究的意义对于模拟人类觅食生态位在各种突出的人类生活史特征的共同进化中的作用具有重要意义，这些特征包括大脑大、寿命长和幼年期延长。
This paper examines changes in hunting ability across the lifespan for the Ache of eastern Paraguay. Hunting ability is decomposed into two components-finding prey and probability of kill upon encounter- and analyzed for important prey species. Results support the argument that skill acquisition is an important aspect of the human foraging niche with hunting outcome variables reaching peaks surprisingly late in life, significantly after peaks in strength. The implications of this study are important for modeling the role of the human foraging niche in the co-evolution of various outstanding human life history characteristics such as large brains, long lifespans, and extended juvenile periods.
