This project studies the relationship between climatic degradation, conflict, and emergent complexity in Chumash society on the Northern Channel Islands and adjacent mainland coast. Previous research has identified substantial reorganization of labor, development of new technologies, and punctuated increases in lethal conflict within Chumash society during the Medieval Climatic Anomaly (MCA), a period of episodic droughts and fluctuating sea-surface temperatures (SST). Very little is known about Chumash social organization and marital patterns prior to Spanish contact, and archaeology is well-suited to reclaiming this knowledge. This research will identify kinship patterns in Chumash society during the MCA by using an innovative combination of archaeogenomic (ancient DNA) and archaeometric (strontium, carbon, and nitrogen isotopes) analysis of ancient Chumash burials. Minimally invasive small tissue samples were taken from ancestral remains under the supervision of the Barbareño Band of Chumash Indians. Resulting data will be contextualized with climatic records for the region and will enhance our understanding of how environmental change affected human social organization over the past two thousand years. This research will substantially aide archaeologists in understanding nuanced ways in which society changes in the context of climate change. The researcher’s indigenous Chumash heritage provides a unique opportunity for this research to positively impact both the Native American and scientific communities. Goals of the proposed research include introducing a diverse array of Native American perspectives within archaeology and development of pedagogical methods to help integrate archaeological research within tribal communities as a form of historical knowledge. Integrating ancient DNA and isotopic method within indigenous archaeological practice serves as a foundation for transformational change between indigenous and academic communities while stimulating important discourse surrounding the future of minimally destructive analysis of indigenous remains in North America. The project will evaluate and add to models broadly focused on how humans respond to short and long-term environmental change and how these changes affect human social organization. This research takes place on the Northern Channel Islands and the adjacent Santa Barbara coastline, areas that have been continuously occupied by the Chumash people. Significant changes in Chumashan society co-occurred with a series of episodic droughts known collectively as the Medieval Climatic Anomaly. This study will couple genome-wide sequencing with stable isotope data from Chumash burials and compare these data to regional climate records to reconstruct changing familial relationships and social structure through time.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该项目研究了北海峡群岛和邻近大陆海岸的Chumash社会中气候退化，冲突和新兴复杂性之间的关系。先前的研究已经确定了劳动力的实质性重组，新技术的发展以及中世纪气候异常（MCA）期间Chumash社会中致命冲突的刺激性增加，这是一段发作的干旱和波动的海面温度（SST）。关于Chumash的社会组织和西班牙接触之前的婚姻模式知之甚少，考古学非常适合回收这一知识。这项研究将通过使用考古学（古代DNA）和考古学（锶，碳和氮同位素分析）的创新组合来确定MCA期间Chumash Society的亲属模式。从祖传中采集的微创小组织样品仍在chumash印第安人的野蛮带的监督下。随着该地区的气候记录，所产生的数据将在上下文中呈上下文，并将增强我们对环境变化在过去两千年中如何影响人类社会组织的理解。这项研究将大大促进考古学家理解社会在气候变化背景下发生变化的细微差别方式。研究人员的土著chumash遗产为这项研究提供了一个独特的机会，可以对美国原住民和科学社区产生积极影响。拟议研究的目标包括在考古学和教学方法的发展中引入一系列潜水员的观点，以帮助部落社区中的考古研究作为历史知识的一种形式。将古老的DNA和同位素方法整合到土著考古实践中，为土著社区和学术社区之间的变革变化而刺激了围绕北美土著土著分析的未来的重要话语的基础。该项目将评估并添加到广泛关注人类对短期和长期环境变化的反应以及这些变化如何影响人类社会组织的模型。这项研究在北部海峡群岛和邻近的圣塔芭芭拉海岸线上进行，这些地区一直被Chumash人民占领。 Chumashan Society的重大变化与一系列被称为中世纪气候异常的情节干旱共同发生。这项研究将将全基因组的测序与稳定的同位素数据结合起来，将这些数据与区域气候记录进行比较，并随着时间的推移重建了不断变化的家庭关系和社会结构。该奖项反映了NSF的法定任务，并被认为是通过基金会的智力优点和更广泛的影响审查标准来通过评估来通过评估来支持的。
