Summary

Analyzing genetic markers in the DNA of individuals from different parts of the world can reveal the migrations of our ancestors. In their Perspective, King and Motulsky discuss a new statistical analysis that-without using prior information about individuals' origins-identifies genetic clusters corresponding to five major geographic regions of the world (Rosenberg et al.). The same analysis confirms that more than 90% of human genetic variation is within populations rather than among groups.
