ABSTRACT

The proposal of an initial human coastal migration into the New World during the late Pleistocene has gained considerable support in recent years. However, the methods of such a migration are not clear and the proposition that it was accompanied by seafaring around the North Pacific to access a kelp highway is still subject to debate. Recent discoveries now suggest that humans crossed Beringia into North America below the ice at least 17,000 years ago. Conversely, in southern California, people are not recorded on the ancient island of Santarosae any earlier than 13,000 years ago. In contrast, the use of seaworthy watercraft is evident only around 10,000 years ago when sea level inundation separated Santarosae into the four present-day islands of San Miguel, Santa Rosa, Santa Cruz, and Anacapa. At this time, early Holocene sea level rise appears to have stimulated watercraft technological innovations.

摘要

近年来，关于在更新世晚期人类沿海最初迁移到新大陆的提议得到了相当多的支持。然而，这种迁移的方法尚不清楚，伴随着北太平洋航海进入海带公路的说法仍存在争议。最近的发现表明，人类至少在 17,000 年前越过白令海峡进入冰层下的北美。相反，在加利福尼亚州南部，早在 13,000 年前，就没有在古老的 Santarosae 岛上记录过人类。相比之下，适航船只的使用仅在大约 10,000 年前，当时海平面淹没将 Santarosae 分为四个现代岛屿：圣米格尔岛、圣罗莎岛、圣克鲁斯岛和阿纳卡帕岛。此时，
