北京大学英语新闻网/Peking University News PKU and Harvard University Working together on the Origin Study of Rice PKU NEWS 2005—04—01 http://ennews.pku.edu.cn/news.php?s=112681295 Peking University, Beijing, April 1, 2005: Since the end of 2004, Department of Archeology of Peking University and Department of Anthropology of Harvard University have jointed hand in the research program of the origin of rice, with its location set in Yu Chanyan cave site at Shou Yan town of Dao county, Hu Nan province. Yu Chanyan is a prehistoric cave once excavated and gained important information by Archeology Research Institute of Hu Nan province in 1993 and 1995. The Sino-America joint archeology team is formed by PKU, Hu Nan Archeology Research Institute, Harvard University and Israel Weizmann Institute of Science, with professor Yan Wenming as the leader of this team, and America National Academy of Sciences Ofer Bar-yosef of the Department of Anthropology of Harvard University as vice leader. Members of the team includes experts in archeology, chronology, paleobotany, agronomy, animal archeology, geology and geomorphology, mineralogy, phytolith, micro-morphology, etc. and graduate students from PKU and Harvard University, which prove to be an important interdisciplinary cooperation in the archeology field of China. Among them, the Chinese team members are professor Li Shuicheng, Wu Xiaohong from Department of Archeology, PKU and professor Xia Zhengkai from Department of Environmental Sciences, PKU, professor Zhang Wenxu from China Agricultural University and scholars from Hu Nan Archeology Research Institute. The excavation this time is of much difference from previous ones in method and means. Intensity is added to the filtration of propagation remains, restoration of paleo-environment, cause of formation of cave accumulation and collection of chrono-specimen, while problems needed to be discussed and solved and research fields involved are much wider, which are the positive driving forces of solving the research problems of the origin of rice, the transition from the Old Stone Age to the New Stone Age and other relevant domains. Moreover, the joint archeology team also carried out experimental archeology and sampling near the excavation spot, the result of which will be used for comparison analysis with the cave sample, in order to go deep into the cause of formation of the ashes accumulated in the cave and the climate and environment conditions then with a result of more scientific explanations. The precise system of working method 1044

The excavation area this time is not very large but the gains are quite plentiful. Besides the digging out of a large amount of bird and aquatic animal fossils, six ancient rice seeds, one piece of original pottery remnant, gravel stoneware, kitchen range pit and fire mound remnant are also among the discoveries, among which the rice seeds and pottery remnant, about 14000 to 15000 years ago by absolute age are the earliest specimen known to be existed in the world so far. These discoveries are of great scientific research value to important international forward tasks such as the exploration of the origin of rice, the invention of pottery, the human living styles, livelihood pattern trait and environmental changes during the transition period from the Old Stone Age to the News Stone Age.
