Abstract: | The origin and evolution of modern Homo sapiens has been the subject of an intensive debate between exponents of two competing hypotheses, multiregional origins and “recent out of Africa”. This paper presents a synthesis of the chronological studies on seven hominid sites in China based on the U-series dating, five of them of intercalated speleothem calcites and other two of fossil materials. The results show that modern humans were present in China about 100 ka ago, much earlier than previously estimated, and that the so-called “temporal gap” of human presence in China between 40 and 100 ka is most probably nothing but an artifact caused by systematic errors of the dating methods. Further multidisciplinary studies on hominid sites in China may provide important evidence for resolving the hotly debated issues concerning the origin of modern humans. |
