　　我看机经里面说有这么一道题，关键词是coastal, clovis, 25000, 40000.利用搜索引擎我找到了这篇文章，目测应该就是GRE的真题啊亲爱的同学们。果断分享中。大家顶起来啊。

　　Recent discoveries in New World archaeology along with new scientific methods for analyzing data have led to new ideas regarding the origin of the first peoples of the Americas and their time of arrival.

　　新大陆考古发现和新的科学方法

　　The traditional theory held that the first Americans crossed the land bridge from Siberia to Alaska around 11,500 years ago and followed an "ice-free corridor" between two large Canadian ice sheets (the Laurentide and Cordilleran) to reach unglaciated lands to the south. These first inhabitants, whose archaeological sites are scattered across North and South America, were called the Clovis people, named after the town in New Mexico where their fluted spear points used for hunting mammoth were first found in 1932.

　　旧观点：11500年前越冰南下，这些批定居者散布在南北美洲，叫做Clovis人。

　　新观点：有更早的12500年前，在智利的MV。

　　There is now convincing evidence of human habitation sites that date earlier than the Clovis culture including sites located in South America. Monte Verde, a well-studied site located along a river near southern central Chile, dates 12,500 years ago. This site contains the buried remnants of dwellings, stone tools including large bifacial projectile points, and preserved medicinal and edible plants. How did people manage to settle this far south at such an early date? A coastal migration route is now gaining more acceptance, rather than the older view of small bands moving on foot across the middle of the land bridge between Siberia and Alaska and into the continents. Emerging evidence suggests that people with boats moved along the Pacific coast into Alaska and northwestern Canada and eventually south to Peru and Chile by 12,500 years ago—and perhaps much earlier. Archaeological evidence in Australia, Melanesia, and Japan indicate boats were in use as far back as 25,000 to 40,000 years ago. Sea routes would have provided abundant food resources and easier and faster movement than land routes. Many coastal areas were unglaciated at this time, providing opportunities for landfall along the way. Several early sites along the coast of Canada, California, Peru, Ecuador, and Chile date between 10,000 and 12,000 years ago. Many potential coastal sites are now submerged, making investigation difficult.

　　这么早他们怎么跑这么远的?新：沿海移民路线;旧：从大陆架中间步行(段那种)。

　　船：沿太平洋海岸线：Alaska-西北加拿大-Peru和Chile;

　　澳大利亚、Melanesia和日本的考古表明25,000 to 40,000 years ago开始有船。

　　沿海路线比路上好。。。容易landfall，很多site被埋了不好挖。
