科学探索与假说推动人类历史 人类迁徙的基因和语言数据 The results of 10 years of nuclear DNA research on Africans,collected by University of Maryland professor Sarah Tishkoff and colleagues,and intended to learn about the origins and migration patterns of all of us,was presented in an article in Science on May 1,2009. The study involved retrieving nuclear DNA from blood samples taken from over 3,000 Africans from 113 ethnic populations throughout the continent of Africa.Scholars from 11 different countries(U.S.,Italy,Germany,France,Cameroon,Mali,Sudan,South Africa,Tanzania,Kenya and Nigeria) took part in this research,which brought centrifuges and other laboratory equipment to the far-flung tribes in Africa, and involved what must have been a hugely complex web of obtaining permits.The study was explained in detail to all participants,as illustrated in this photograph from the project. The DNA was compiled and then integrated with data from the Human Genome Diversity Panel,leading the researchers to several interesting findings,that speak to the origins of humans and the migration patterns that are in evidence. Tishkoff and colleagues have built a database that will be made available to other researchers.They also performed some preliminary analysis of their own.The next few pages will discuss some of the results already realized by the study. http://archaeology.about.com/od/stoneage/ss/tishkoff.htm Tishkoff,Sarah A.,et al.2009 The Genetic Structure and History of Africans and African Americans.Science Express.30 April 2009 2022-3-11 10
