俄罗斯堪察加半岛的乌什基旧石器时代遗址长期以来一直被认为包含了对美洲人至关重要的信息，特别是克洛维斯的起源。新的放射性碳年代测定表明，人类对乌什基的占领始于13,000年前，比以前认为的晚了近4000年。虽然双面工业在北美西部的克洛维斯时代就已经遍布白令吉亚，但这些数据表明，晚冰期的西伯利亚人直到更新世末才扩散到白令吉亚，也许是最近才扩散到美洲的前克洛维斯人群的祖先。
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.
