Clovis People

I’m Ann Kellen with Science and Technology Today. The conventional(1) theory is humans first came to the America’s across the land bridge from Asia about 11,500 years ago, the so-called Clovis people. But the discovery of a site(2) 1000 years older in South America raised questions and started archeologist【考古学家】 Michael Collins on a quest(3) to find evidence(4) of pre Clovis people in North America, Specifically(5)in Belle County, central Texas.

“We see hints(6), whispers that maybe there are some earlier cultural remains(7) there , can’t say it for sure yet. ”

What Collins has found is an artifact(8) rich site where Clovis people apparently(9) returned again and again.

“Which is different than the usual idea of nomadism【游牧生活】.”

Clovis’ occupation(10) is marked by spear【矛;鱼叉】 points and one of the best materials for making those spear points is the stone found at the Texas site.

克洛维斯人

这里是今日科技，我是安•凯伦。传统的观念认为第一批来到美洲的人类是一万一千五百年前的亚洲人，他们跨越海峡来到美洲，即所谓的克洛维斯人。但是在南美洲发现了一处比此还要早一千年的遗址，此发现向这一观念提出了质疑，由此促使了考古学家米歇尔•柯林斯开始试图在北美洲，具体的说是德州中部的贝拉县，寻找前克洛维斯人存在的证据。

“我们发现新的线索，它可能说明那里存在着更早的人类文明，只是还不能够确定而已。”

柯林斯发现的是一个石器物群遗址，各种古石器证明克洛维斯人曾在此居住，并经常迁徙于亚洲和美洲之间。

“这跟平常我们认为他们是游牧生活的想法有些不同。”

梭镖是克洛维斯人的日常生活的重要标志，而用来制做这些梭镖的最好原料之一就是来自德州遗址的石头。
