"Prehistoric" covers a huge span of time. While the number of samples of "prehistoric" DNA has increased dramatically, I think caution is required in interpreting the results. The patterns that are emerging could easily be upset by new samples, and that seems to be what is actually happening: every couple weeks, ancient samples seem to reveal some new interaction or migration of prehistoric populations. I think it will be a few years, and many thousands more samples sequenced, before things begin to settle down.

Reich would agree. His approach was not intended to give the final word
