As I have noted before one of the consequences of genomic analysis techniques becoming relatively cheap and accessible is that they are now viable tools toward exploring a host of fundamentally non-genetic questions. That is, instead of exploring the dynamics of evolutionary biology, they can be used to shed light upon other sorts of dynamics. Sometimes the questions are fuzzy and the techniques can be laborious; e.g., the extraction and analysis of ancient DNA and their subsequent insertion into an explanatory framework where the non-genetic data are patchy. On other occasions, the interpretations are easier. Consider the demographics of Argentina:
