  Their thirst for hunting is blamed by some experts for the sudden disappearance of mammoths, mastodons and other large 'megafauna' mammals from the continent. But it appears there were other humans doing the same thing hundreds of years earlier.

  一些专家指责,这些克劳维斯人对狩猎的渴望是猛犸象、乳齿象以及巨型哺乳动物群从大陆突然消失的原因。然而,现在看上去好像其他人类比那早几百年前就做了同样的事情。

  Professor Eske Willerslev, from the University of Copenhagen in Denmark, who led the research, said: “It is proof that other hunters were present at least 1,000 years prior to the Clovis culture. The 'Clovis First' theory, which many scientists swore to just a few years back, has finally been buried with the conclusions of this study. ”

  领导这项研究的、来自丹麦哥本哈根大学的Eske Willerslev教授说:“其他狩猎者出现于北美大陆的时间至少比克劳维斯文明早1000年。这一结论彻底埋葬了几年前许多科学家断定的‘克劳维斯文明第一’的理论。”

  “At this time, however, we do not know if it was the man-made hunt for the mastodons, mammoths and other large animals from the so-called megafauna, which caused them to become extinct and disappear. Maybe the reason was something completely different, for instance the climate.”

  “可是,我们现在还无法知道这一人造狩猎工具到底是不是造成所谓巨型动物群内乳齿象、猛犸象及其他巨型动物灭绝和消失的原因。或许灭绝原因是和这完全不同的东西,比如说气候。”
