项目摘要

Determining the ages of archaeological sites is essential for assessing the timing and rates of human behavioral and biological evolution, and for synchronizing archaeological, fossil, and paleoenvironmental records across sites. Current techniques for dating archaeological sites do not fully meet these needs, especially at sites older than 50 thousand years. This project will develop 1) a new approach for determining ages and apply it to several important Middle Stone Age archaeological sites, and 2) a technique that uses archaeological materials to provide paleoenvironmental reconstructions for these sites during human occupation. The project will enhance the infrastructure for archaeological research across existing laboratories, allowing more informative study of museum collections that may contain unique or irreplaceable artifacts. The investigators will promote teaching, training and learning by engaging undergraduate science majors, technicians conducting the research, and a female PhD candidate who is a first-generation college attendee, in novel analytical protocols and approaches to data interpretation. The project will also support international collaborations, research, and science outreach, at sites that include a UNESCO-World Heritage Center.The archaeological record of the Middle Stone Age (300 thousand to 30 thousand years ago) is critical for understanding the biological and behavioral origins of our species, Homo sapiens. It encompasses the earliest known fossils of anatomically modern humans, provides abundant evidence for accelerated behavioral innovation relative to prior intervals, and coincides with the expansion of modern humans out of Africa. In this project, stable isotope and uranium-thorium dating of ostrich eggshells will be applied at sites in eastern and southern Africa that record the Middle Stone Age. The project will develop and apply uranium-thorium dating of ostrich eggshells, a common material in Old World archaeological sequences, and will employ stable isotopes of carbon, nitrogen, and oxygen in ostrich eggshell to provide improved local records of past mean annual precipitation, vegetation, and aridity. In sum, these dual methods will enhance archaeologists' ability to extract chronological and paleoenvironmental information from many Old World archaeological sequences and will advance understanding of the timing, tempo, and driving factors of Middle Stone Age behavioral and cultural innovations.
确定考古遗址的年龄对于评估人类行为和生物进化的时间和速度以及同步考古,化石和古环境记录跨站点至关重要。 目前用于确定考古遗址年代的技术不能完全满足这些需求,特别是在5万年以上的遗址上。 该项目将开发1)确定年龄的新方法,并将其应用于几个重要的中石器时代考古遗址,以及2)使用考古材料为人类占领期间的这些遗址提供古环境重建的技术。该项目将加强现有实验室的考古研究基础设施,从而对可能包含独特或不可替代的文物的博物馆藏品进行更多信息研究。研究人员将通过吸引本科科学专业的学生,进行研究的技术人员以及第一代大学生的女博士候选人来促进教学,培训和学习,以新颖的分析协议和数据解释方法。该项目还将支持包括联合国教科文组织-世界遗产中心在内的地点的国际合作、研究和科学推广。中石器时代(30万至3万年前)的考古记录对于理解我们物种智人的生物和行为起源至关重要。它包含了已知最早的解剖学上的现代人类化石,为相对于先前的时间间隔加速行为创新提供了丰富的证据,并且与现代人类从非洲扩张的时间相吻合。 在该项目中,将在非洲东部和南部记录中石器时代的地点对鸵鸟蛋壳进行稳定同位素和铀-钍年代测定。该项目将开发和应用鸵鸟蛋壳的铀-钍年代测定,鸵鸟蛋壳是旧世界考古序列中的一种常见材料,并将使用鸵鸟蛋壳中碳、氮和氧的稳定同位素,以提供过去平均年降水量、植被和干旱的更好的地方记录。 总之,这些双重方法将提高考古学家从许多旧世界考古序列中提取年代和古环境信息的能力,并将促进对中石器时代行为和文化创新的时间,克里思和驱动因素的理解。
