Description:
The Ushki Paleolithic sites of Kamchatka, Russia, have long been thought to contain information critical to the peopling of the Americas, especially the origins of Clovis. New radiocarbon dates indicate that human occupation of Ushki began only 13,000 calendar years ago-nearly 4000 years later than previously thought. Although biface industries were widespread across Beringia contemporaneous to the time of Clovis in western North America, these data suggest that late-glacial Siberians did not spread into Beringia until the end of the Pleistocene, perhaps too recently to have been ancestral to proposed pre-Clovis populations in the Americas.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Goebel, Ted -- Waters, Michael R -- Dikova, Margarita -- New York, N.Y. -- Science. 2003 Jul 25;301(5632):501-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Anthropology/096, University of Nevada Reno, Reno, NV 89557, USA. goebel@unr.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12881567" target="_blank"〉PubMed〈/a〉
