Confirmation by modern genetic studies of the traditional racial classification categories
What are the percentages of genetic differences between the human races, indicating their relationships? Perhaps the best global scale study to date on this subject is still that of Masatoshi Nei and Arun K. Roychoudhury from Evolutionary Relationships of Human Populations on a Global Scale (1993). Subsequent studies, which have included increasing numbers of alleles but have usually been regional rather than global in scale, have been consistent with Nei and Roychoudhury’s results. The following table (Fig. 1 below) of estimates of genetic differences between human populations is from their study.
