The Chronology and Ecology of Postglacial Colonization of the Americas

人类在美洲的殖民一直是一个重要而有争议的问题。在11000年前克洛维人的扩张中尤其如此。新的日期表明，一种大型哺乳动物，驼鹿，跟随人类从西伯利亚到阿拉斯加的相同路线。由于这两个地区在这段时间内从未发现过人类骨骼，大量驼鹿骨骼的存在为分析这些共同旅行者的时间和生态限制提供了机会。来自西伯利亚东北部、阿拉斯加和育空地区的60个放射性碳年代将提供林地环境和人类/驼鹿共同扩张到新世界的程度的间接指标。

Human colonization of the Americas has been an important and controversial issue. This is particularly true with regard to the Clovis expansion shortly before 11,000 years ago. New dates suggest that one large mammal, the moose, followed the same route as humans from Siberia into Alaska. Since human bones have never been found in either region from this time period, the presence of large numbers of moose bones offers an opportunity to analyze the timing and ecological limits of these co-travellers. Sixty radiocarbon dates from northeastern Siberia, Alaska and the Yukon will provide an indirect indicator of the extent of the woodland environments and human/moose co-expansion into the New World.
