You don't need distinct races or even a precise definition of the term to find traces of migrations in the genome. If you start with a population[], partially isolate it into two subgroups, then mix them again after a while, you can already detect a different pattern in their genetic variation than had they remained a single population. [] Population geneticists have decided to talk about different populations, just to avoid the term "race". I think that's dumb. Instead of using an even more ill-defined term, they could just have defined race properly.
