| A Tentative Discussion on the Age of the Ancient Human Occupation of the Nihewan Basin |
| The Nihewan Basin, where many early Pleistocene Paleolithic sites have been unearthed,could play an important role in understanding the history of human evolution and the speed of Human's Paleolithic culture diffusion in China. It could also serve as a good example of exploring how ancient human beings coped with the temperate areas even in the early Pleistocene. However, since the first early Paleolithic site Xiaochangliang was found in 1978, no agreement has yet been reached on the problem when human beings began to inhabit the Nihewan Basin. As more and more early Paleolithic sites have been uncovered,this question needs to be reconsidered seriously. In this paper,the opinions voiced by different researchers on the dates of the early Paleolithic sites are listed and the causes of the existence of different opinions are analyzed. In the end, an age of 1.2～1.0 Ma B P was proposed for the Human's first occupation of the Nihewan Basin based on synthesizing the paleoenvironment and the "Homo erectus's geographic expansion"which occurred worldwide at about the same time. |
