| 1 | Revisiting the origin of modern humans in China and its implications for global human evolution显示文摘The debates over the origin of modern humans have long been centered on two competing theories:the 'Out-of-Africa'(single-place origin) theory and the 'Multi-regional Evolution' theory.China is an extremely important region where many ancient human fossils were collected along with numerous associated faunal remains and artefacts.These cultural remains,unearthed from different areas in the country and covering a long time span,will help clarify the controversy.The study of cultural materials in China is expected to shed important light on biological evolutionary patterns and social and technical developments of those early humans as well as their environmental conditions.Based on the analysis of Chinese fossils and associated materials,in conjunction with some genetic studies,this paper aims at evaluating each of the two theories in order to stimulate more discussions.Our study suggests that the evolutionary model of 'Continuity with Hybridization' is most relevant in reflecting the current understanding of human evolutionary history in China.Furthermore,we propose that the concept of regional diversity of evolutionary models should be seriously considered to illustrate different evolutionary modes applied to different parts of the world. | GAO Xing1,2*,ZHANG XiaoLing1,2,3,YANG DongYa2,4,SHEN Chen2,5 & WU XinZhi1,2 1 Institute of Vertebrate Paleontology and Paleoanthropology,Chinese Academy of Sciences,Beijing 100044,China 2 Laboratory of Human Evolution,Chinese Academy of Sciences,Beijing 100044,China 3 Graduate University of Chinese Academy of Sciences,Beijing 100049,China 4 Department of Archaeology,Simon Fraser University,Vancouver V5A 1S6,Canada 5 The Royal Ontario Museum,Toronto M5S 2C6,Canada | 2010 | Science China Earth Sciences2010，53，12： | 11 |
| 3 | 西洋参生产的技术选择和挑战显示文摘近年来,西洋参的生产量在世界上急剧增加,有必要对其进行全面评价。从系统性考虑,西洋参生产的主要要素包括种子的处理和种植、适宜生长环境的建立和保持。植株健壮的保持、收获和收获后处理以及生产工艺等环节。在增长的全球性竞争中,精明的做法是要对西洋参生产环节的强弱做精细的评估分析,显然,先进而且适宜技术的采用是关系到工业化生产是否成功和是否取得经济效益的关键。技术的精心选择和不断改进都是成功的面对不断增加竞争性的西洋参市场挑战所必需的。 | W.
