| 摘 要： | 现代人类起源的时间和地点是当前古人类学研究和争议的热点。文中评述了 2 0多年来第四纪测年技术取得的进展及其对现代人类起源研究的影响。基于新生碳酸盐岩铀系测年 ,研究了中国南方柳江人洞等多个晚期人类化石地点的年代 ,结果远大于原认为的 2 0～ 30ka。晚期智人在中国出现的时间很可能不晚于西亚和南非 ,中国 4 0～ 1 0 0ka间人类化石的“缺环” ,很可能只是测年技术系统误差造成的假象。上述年代学新证据不支持中国现代人类全部来自非洲的假说。对岩溶洞穴遗址进一步的综合研究 ,有可能为破解有关现代人类起源的诸多疑点提供重要的以至一锤定音的证据

| Abstract: | The occurrence and evolution of anatomically modern Homo sapiens have been the subjects of controversy between exponents of two major competing hypotheses: multiregional origins versus “recent out of Africa”. This paper makes a brief review on the technical advances in Quaternary geochronology achieved during the past over 20 years and their impacts on the timescale of recent human evolution. Based on the U-series dating of intercalated speleothem formations, the chronology of several hominid sites in southern China, including the cave of Liujiang hominid, have been studied. The results show that these sites are much older than the previously estimated age of 20～30 ka. The appearance of modern Homo sapiens in southern China may be an event occured as early as that in West Asia and South Africa. The so-called “temporal gap” of human presence in China between 40 and 100 ka is most likely nothing but an artifact caused by systematic errors of the dating methods. The above chronological evidence does not support the “recent out of Africa” hypothesis. Further multidisciplinary studies on hominid sites in China may provide important evidence for resolving the hotly debated issues concerning the origin of modern humans. |
