New evidences support that Chinese originated from
Professors Jin Li, et al of anthropology research center, Fudan University, chief of department of environmental health and genomic information center, Medical College, University of Cincinnati, USA, had already published papers as early as 3 years ago pointing out that at present the Asiatic gene bank chiefly originated from the modern people of African source, and overthrew the conclusion of a long existing theory of the successive evolution from the upright posture to the modern people in the Eastern Asiatic regions. Professor Jin Li presented his theme speech entitled "the research on diversity of Chinese genome", which confirmed again the origination of the Chinese people from Africa.
Professor Jin Li recommended that his project had conducted DNA sampling action in a total of 120 population group in 56 nationalities consisting of Ewenki minority to the north of Helongjiang province, to the west of the Uygur nationality in Xinjiang, to the south of 28 chief population groups of Yunnan province, to the east of the few branches in Taiwan Kaoshan national minority in Taiwan, and obtained DNA sampling in totally 120 collective groups; it was discovered after detection of more than 12000 individuals that a mutation site M168G existed at the Y chromosone of nearly 10000 male specimens covering the various provinces, municipalities and autonomous regions in China. And this was the mutation site developed in Africa approximately 79 thousand years ago, which was a unique genetic marker partially found in African people. Jin Li pointed out that recombination of Y chromosome did not occur during human hereditary procedure and Y chromosome was able to record human hereditary information in a steady and rich manner. Following the research of Y chromosome, it was suspected that the ancestors of human being departed from Africa and migrated to various places of the world in approximately 60 thousand years ago, and a subdivision of the Africans moved from the south eastern Asia to the north and arrived in China, went across the Yangtze river and entered north China and north eastern China, and became the ancestors of the Chinese people of the present era., 百拇医药
