据证实，现代人生活在黎凡特和非洲。十万年前。然而，这与中国的情况形成对比，中国没有明确的本种标本被安全地定年到30 ka以上。本文介绍了柳江人科化石发现地通天岩洞穴的地层学研究和铀系测年结果，该洞穴是我国保存较好的现代智人化石之一。人类化石被推断来自一个再充填的角砾岩或主要沉积的含砾石的桑迪粘土层。在前一种情况下，这是更好的支持，化石的日期将至少类似于68 ka，但更有可能类似于111-139 ka。或者，它们的年龄可能大于，类似于153 ka。这两种情况都使柳江人科成为东亚最早的现代人类之一，可能与黎凡特和非洲已知的最早的代表是同一时期的。在中国其他地区的平行研究为柳江的重新定年提供了支持性证据，这可能对现代人类的起源有重要意义。(C)2002爱思唯尔科技有限公司版权所有。
It has been established that modern humans were living in the Levant and Africa ca. 100 ka ago. Hitherto, this has contrasted with the situation in China where no unequivocal specimens of this species have been securely dated to more than 30 ka. Here we present the results of stratigraphic studies and U-series dating of the Tongtianyan Cave, the discovery site of the Liujiang hominid, which represents one of the few well-preserved fossils of modern Homo sapiens in China. The human fossils are inferred to come from either a refilling breccia or a primarily deposited gravel-bearing sandy clay layer. In the former case, which is better supported, the fossils would date to at least similar to 68 ka, but more likely to similar to 111-139 ka. Alternatively, they would be older than, similar to 153 ka. Both scenarios would make the Liujiang hominid one of the earliest modem humans in East Asia, possibly contemporaneous with the earliest known representatives from the Levant and Africa. Parallel studies on other Chinese localities have provided supporting evidence for the redating of Liujiang, which may have important implications for, the origin of modem humans.
