Some thoughts on epigenetics
A fascinating new area of genetic studies focuses on changes of gene expression that do not involve underlying DNA structure.(epi:above,over; genetics). Without getting too much into the science of it, the implications are immense; we could be altering gene expression over generations without altering the DNA code. In behavioral medicine this could mean alterations of this expression via life experiences. Could then your grandparents experiences of depression, religious persecutions, and or war have any effect on your genetic expression? and could your adaptations to life events and challenges in turn alter your epigenetic expression in generations to come? The science is new and these questions remain mostly unanswered but amazingly relevant and interesting.
