三万至四万年前人类在青藏高原的最早活动

The earliest human inhabitants on the high-altitude Tibetan Plateau prior to 40000- 30000 years ago

青藏高原是史前时期人类征服高海拔极端环境的最高、最早纪录的地区之一。坐落于海拔4600米以上的西藏尼阿木底遗址的活动年代距今有3至4万年历史,也是全球范围内确定的海拔最高的旧石器时代遗址。该遗址发现的大量石片组合,表明了古人类适应环境能力的认识和行为能力发展的新高度。这一发现,己成为人类最早居住或登上世界屋脊的有力证据,对澄清学界和大众对青藏高原人类生存历史的普遍认识具有重要的现实意义。

The Tibetan Plateau-- the highest plateau in the world, is one of the most demanded environments ever inhabited by human beings. We made investigation of the timing and mechanisms of its initial colonization at the Nyadi site, located nearly 4600 meters above sea level. This site, dating 40,000 to 30,000 years from now, is the highest Paleolithic archaeological site so far identified internationally. Nyadi has yielded an abundant blade tool assemblage, indicating hitherto?unknown capacities for the survival of modem humans who camped in this environment. This site provides the evidence about the early human inhabitants on the “roof of the world” and the history of human inhabitants on the high-altitude place.
