Speaking of epigenetics, does anyone know if this additional material (I guess you could call it genetic metadata) could be used in genealogy? According to the article, it can alter per generation, but there is no real indication of how rapidly changes occur, whether the epigenetic material around the Y chromosome is patrilinear, whether there is similar matrilinear epigenetic material around mtDNA, etc.
Since it seems to alter according to environment in addition to any other random mutation, if there are sufficiently stable regions, it might be helpful tracking human migration, as migrations must impose some sort of change (or the people involved probably wouldn't bother).
It might also be helpful in finding out information routine genetic genealogy or genetic archaeology wouldn't reveal (such as the presence of certain types of stressor).
What's the current state-of-play in using epigenetics in genetic genealogy or in genetic archaeology? IS there a current state-of-play? If there isn't, is it because the subject is too new, too expensive, too insufficiently explored or too full of rapid variables to be useful?
