讲故事可以通过传递信息和加强文化行为准则来影响健康和健身。尽管他们的潜在的重要性，讲故事的技能的发展和时间，以及故事知识的传播得到了最少的关注，在生计社会的研究，更经常关注粮食生产技能。在这里，我们研究如何讲故事和Tsimane觅食园艺之间的信息传输模式预测的讲故事的能力和积累的经验的年龄变化。我们发现，讲故事的技能是最发达的老年人谁表现出上级知识的传统故事，谁报告讲故事最。我们发现，通过讲故事传递的重要信息通常是从年长的一代传递给年轻的一代，而故事主要是从年长的同性亲属，特别是祖父母那里学到的。我们的研究结果表明，口头传统提供了一个专门的晚年服务利基Tsimane成年人积累了重要的经验和知识相关的觅食和社交，但失去了比较优势，在其他生产领域。这些发现可能有助于扩展我们的理解进化的人类生活史，说明如何体现资本的变化预测的信息传输服务的发展，在一个forager-horizontalist经济。
Storytelling can affect wellbeing and fitness by transmitting information and reinforcing cultural codes of conduct. Despite their potential importance, the development and timing of storytelling skills, and the transmission of story knowledge have received minimal attention in studies of subsistence societies that more often focus on food production skills. Here we examine how storytelling and patterns of information transmission among Tsimane forager-horticulturalists are predicted by the changing age profiles of storytellers’ abilities and accumulated experience. We find that storytelling skills are most developed among older adults who demonstrate superior knowledge of traditional stories and who report telling stories most. We find that the important information transmitted via storytelling typically flows from older to younger generations, and stories are primarily learned from older same-sex relatives, especially grandparents. Our findings suggest that the oral tradition provides a specialized late-life service niche for Tsimane adults who have accumulated important experience and knowledge relevant to foraging and sociality, but have lost comparative advantage in other productive domains. These findings may help extend our understanding of the evolved human life history by illustrating how changes in embodied capital predict the development of information transmission services in a forager-horticulturalist economy.
