Collaborative Research: Reproduction, Kinship, and Coalition Violence

（与Boster， Erickson， Yost - BCS 9910465合作）本项目将调查厄瓜多尔东部一个土著群体中男性联盟暴力（“战争”）的感知动机和生物适应性后果。瓦奥拉尼人（Waorani）是一个以好战著称的平等主义热带森林园艺师群体。由于内部暴力，他们经历了极高的死亡率，其影响在仍然活着的人的生活史中仍然突出。参与男性联合暴力的程度因人而异，因此提供了研究参与暴力的感知动机和不同程度的好战的生殖后果的可能性，这是当代文化人类学的一个重要问题。这项研究将测试一些关于个人战争动机和繁殖优势之间关系的假设。方法包括收集400名Waorani成年男女的生活史、社交网络数据、生殖和家庭历史以及个人动机。这个项目将有助于我们理解战争的动机和后果。

Beckerman - - BSC-9910445 (Collaborative with Boster, Erickson, Yost - BCS 9910465)This project will investigate the perceived motivations for and the biological fitness consequences of male coalitional violence ("warfare") in an indigenous group in eastern Ecuador. The Waorani (a linguistic isolate) are a famously warlike group of egalitarian tropical forest horticulturalists. They have experienced extraordinarily high levels of mortality due to internal violence, the effects of which remain prominent in the life histories of people still living. The level of participation in male coalitional violence varies substantially form man to man, thus affording the possibility of studying both the perceived motives for participation in violence and the reproductive consequences of varying levels of bellicosity, an important issues in contemporary cultural anthropology. The research will test a number of hypotheses concerning the relationship between individual motivations for warfare and reproductive advantage. Methods include the collection of life histories, social network data, reproductive and household histories, and individual motivations from 400 Waorani male and female adults. The project will contribute to our understanding of the motivations and consequences of warfare.
