摘　　要： 　现代人起源是当前古人类学研究的热点,"多地区连续演化"和"非洲起源"两种主要假说已争论多年.近年来新的分子生物学和年代测定技术在这一领域中的应用,使论战愈加激化.本实验室基于铀系测年技术,研究了我国南方多个中、晚更新世人类遗址的年代,结果表明中国也存在约10万年前的现代人遗址.现代人在中国出现的时间很可能不晚于非洲和西亚.上述年代学新证据不支持中国现代人起源于非洲的假说. The appearance of anatomically modern Homo sapiens is a hotly debated issue in paleoanthropology. Specialists and lay people alike now tend to recognize two major models, i.e. 'out of Africa' and 'multiregional evolution'. In recent years, new chronological and molecular biological techniques have been applied in this area. Based on U-series dating, several sites in South China, such as Liujiang, Ganqian and Bailiandong caves, have been studied. The results show that all the three sites are much older than previously assigned age of 20～30 ?ka. The appearance of modern Homo sapiens in South China may be an event as early as in West Asia and Africa.
