项目摘要

Dr. Loren Davis of Oregon State University and Dr. Matthew Des Lauriers of California State University-Northridge, along with colleagues in Mexico, will conduct research to study the earliest archaeological evidence of marine environmental use along the Pacific coast of the Americas. Current archaeological evidence indicates that humans migrated from northeastern Asia into North America and spread throughout the rest of the Americas. As part of this research theme, archaeologists are interested in learning about the timing and route that humans initially took to migrate into the Americas. One main hypothesis on this theme asserts that people used a hunting-gathering-fishing lifeway to spread from northeastern Asia into North America and beyond by initially traveling along the Pacific coastline around the glaciated margins of Alaska and Canada. If this is true, archaeologists expect that early coastal sites should contain artifacts and the remains of animals that reveal the application of effective technologies used to extract a living from a broad range of marine environmental resources. Finding archaeological sites that show early North Americans peoples possessed a full mastery of marine environments would add confirmatory evidence to support the Pacific coastal migration hypothesis. The team will generate and share interdisciplinary knowledge about the history of changing coastal environments on Cedros Island and how humans lived in a changing coastal context. This international collaborative project will generate critical knowledge about the larger issue of the initial human settlement of the Americas and in the process will provide unique educational opportunities for students and the public alike.Drs. Davis and Des Lauriers will lead a research team to examine how early coastal peoples used fishing and hunting technologies to exploit the full range of Pacific marine resources from nearshore to deep-water offshore biomes. The research will be conducted on Cedros Island, which is located in northwestern Mexico along the Pacific coast of Baja California. This island is special because it retains many well preserved archaeological sites clustered around ancient freshwater springs that were undoubtedly attractive places for early peoples to repeatedly settle and in the process create a record of their lives that accumulated over hundreds to thousands of years. The researchers will lead a team of archaeologists, geoarchaeologists, and environmental scientists to conduct excavations at four sites that are known to contain artifacts and marine animal remains that date earlier than 12,000 calendar years old. The team will also study local geological records that date to the early period of human occupation in order to better understand the environmental context in which coastal people lived.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.

俄勒冈州州立大学的Loren Davis博士和加州州立大学北岭分校的Matthew Des Lauriers博士沿着墨西哥的同事将进行研究，研究美洲太平洋沿岸海洋环境使用的最早考古证据。目前的考古学证据表明，人类从东北亚迁移到北美，并遍布美洲其他地区。作为这一研究主题的一部分，考古学家有兴趣了解人类最初迁移到美洲的时间和路线。关于这一主题的一个主要假设认为，人类最初是通过沿着阿拉斯加和加拿大冰川边缘的太平洋海岸线，以狩猎-采集-捕鱼的生活方式从东北亚传播到北美和更远的地方。如果这是真的，考古学家预计，早期的沿海遗址应该包含文物和动物遗骸，揭示了用于从广泛的海洋环境资源中提取生物的有效技术的应用。发现考古遗址表明早期北美人拥有对海洋环境的充分掌握，这将为支持太平洋沿岸移民假说提供确凿的证据。该团队将产生和分享关于塞德罗斯岛沿海环境变化的历史以及人类如何在不断变化的沿海环境中生活的跨学科知识。这一国际合作项目将产生关于美洲最初人类定居这一更大问题的关键知识，并在此过程中为学生和公众提供独特的教育机会。戴维斯博士和德斯劳里耶斯博士将领导一个研究小组，研究早期沿海居民如何利用捕鱼和狩猎技术，从近岸到深海开发太平洋海洋资源，近海生物群落研究将在塞德罗斯岛进行，塞德罗斯岛位于墨西哥西北部沿着下加利福尼亚太平洋沿岸。这个岛屿很特别，因为它保留了许多保存完好的考古遗址，这些遗址聚集在古老的淡水泉周围，这些淡水泉无疑是吸引早期人们反复定居的地方，并在此过程中创造了数百至数千年来积累的生活记录。研究人员将带领一个由考古学家、地质考古学家和环境科学家组成的团队，在四个已知含有史前古器物和海洋动物遗骸的地点进行挖掘，这些古器物和海洋动物遗骸的历史早于12,000年。该团队还将研究当地的地质记录，可以追溯到人类占领的早期，以更好地了解沿海人民生活的环境背景。这个奖项反映了NSF的法定使命，并已被认为是值得支持的，通过评估使用基金会的知识价值和更广泛的影响审查标准。
