The findings may validate the feelings of anyone oppressed or suffering long-term deprivation, but what does it really mean for their descendants? For example, what were the long-term effects, not just for black Americans, but for survivors of the Irish Potato Famine or the Holocaust? And if the effects were negligible for these latter two groups, what does that mean for the former?

Considering most humans in most places at most times lived in deprived circumstances, I wouldn't jump to conclusions just yet on the nature of Schmitz et al.'s findings. Remember their findings 'could be linked,' not 'are linked.'
