Epigenetics: The Ultimate Mystery of Inheritance by Richard Francis. This is a new field of research in molecular genetics which has revealed that certain chemical which are attached to DNA can alter the behavior of genes. These gene regulating attachments can have long lasting effects (sometimes life-long). Also, in some cases, epigenetic attachments can be passed on, along with the genes to which they are attached to the next generation. Click on the picture on the right (from Wikipedia) to see a brief overview of epigenetics.
What is interesting about all of this, I think, is that these epigenetic attachments, which regulate gene expression, and which can sometimes be inherited, are themselves caused by external influences not only within body cells but also from far away in the body and even outside of the body. For example, a social interaction you are having may be stressful for you which may set in motion a process, through a series of steps, of creating certain epigenetic attachments.
The traditional way of viewing the gene as the director is being overhauled. The gene itself is directed by the cell which is being directed by outside influences. Genes remain very important but the degree to which genes are expressed is a matter of how genes are regulated from the outside.
My question is: Is this relevant at all to the solution-focused approach? If so, how?
