Relationship between the Ancients Migration and Climate Change in the Later Period of Late Pleistocene in Tibet
晚更新世以来西藏古人类迁移与气候变化关系

Based on examinations of the culture characters from late Paleolithic age to late Neolithic age by math method, we discover three times large-scale ancients remove in history. First, about 50 KaBP-10 KaBP, the southern ancients removed to the north of Tibet. Second, about 6 KaBP-3.6 KaBP, the northern ancients removed to east of Tibet. Third, about 3 KaBP-2.2 KaBP, the eastern ancients removed to the middle part of Tibet. The remove laid the foundation for the formation of later culture in Tibet. We also discover that the climate is the main cause of the ancients' remove. The consequence of the great remove is a fusion of different cultures which produced a new culture, because the migrants served as the crowed is only carrier of the information about the technique and the experience before the appearance of the writing system. Thus the information is expressed by population. We give the method to study the culture remove and change by determining a more similar culture with the given culture via the similar coefficient. Finally, whether or not paleoanthropologic character, especially, the features of are identical between the two cultures.
