长期以来科学家们认为,许多美洲印第安人是早期横渡太平洋的中国水手的后裔。美国生物化学家通过对印第安人脱氧核糖核酸(DNA)的分析为这种看法提供了佐证。 据英国《星期日电讯报》21日报道,美国佐治亚州亚特兰大埃默里大学的道格拉斯·华莱士教授及其同事,最近在美国人类学协会的一次会议上报告说,现在活着的美洲印第安人的部分DNA与亚洲、波利尼西亚群岛和美拉尼西亚群岛上的土著人的DNA是相同的。 华莱士教授及其同事是通过研究线粒体DNA而得出上述结论的。这种线粒体DNA中含有37个基因,这些基因总是从母亲遗传给孩子,因此在跟踪血缘方面是不会出错的。华莱士教授的同事塞奥多尔·施舒尔博士说,现在看来,史前有两次从亚洲移往美洲的移民大浪潮。第一次发生在2万到4万年 For a long time scientists think many Native Americans are descendants of early Chinese sailors who crossed the Pacific. This is supported by the biochemists’ analysis of Native American DNA (DNA). According to the 21st Century Daily Telegraph reported that Professor Douglas Wallace of Emory University in Atlanta, Georgia, and his colleagues recently told a meeting of the American Anthropological Association that currently living American Indians Some of the DNA is identical to that of indigenous peoples in Asia, the Polynesian and Melanesian islands. Professor Wallace and colleagues came to this conclusion by studying mitochondrial DNA. This mitochondrial DNA contains 37 genes, these genes are always inherited from the mother to their children, so tracking blood is not wrong. Dr. Walter Shiosoul, a colleague of Wallace, said it now appears that there were two waves of prehistoric migration of immigrants from Asia to the Americas. The first occurred in 20,000 to 40,000 years
