美國(guó)遠(yuǎn)古人的起源時(shí)間
分享一篇GRE2月機(jī)經(jīng)所說(shuō)的原文
我看機(jī)經(jīng)里面說(shuō)有這么一道題，關(guān)鍵詞是coastal, clovis, 25000, 40000.利用搜索引擎我找到了這篇文章，目測(cè)應(yīng)該就是GRE的真題啊親愛的同學(xué)們。果斷分享中。大家頂起來(lái)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.
新大陸考古發(fā)現(xiàn)和新的科學(xué)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.
舊觀點(diǎn)：11500年前越冰南下，這些第一批定居者散布在南北美洲，叫做Clovis人。
新觀點(diǎn)：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.
這么早他們?cè)趺磁苓@么遠(yuǎn)的？新：沿海移民路線；舊：從大陸架中間步行（第一段那種）。
船：沿太平洋海岸線：Alaska-西北加拿大-Peru和Chile；
澳大利亞、Melanesia和日本的考古表明25,000 to 40,000 years ago開始有船。
沿海路線比路上好。。。容易landfall，很多site被埋了不好挖。
