WHAT IS EPIGENETICS?
The development and maintenance of an organism is orchestrated by a set of chemical reactions that switch parts of the genome off and on at strategic times and locations. Epigenetics is the study of these reactions and the factors that influence them.

“We commonly accept the notion that  through our DNA we are destined to have particular body shapes, personalities, and diseases. Some scholars even contend that the genetic code predetermines intelligence and is the root cause of many social ills, including poverty, crime, and violence. ”

“Epigenetics is proving we have some responsibility for the integrity of our genome,” Jirtle says. “Before, genes predetermined outcomes. Now everything we do—everything we eat or smoke—can affect our gene expression and that of future generations.”

“Until recently, the pattern of an individual’s epigenome was thought to be firmly established during early fetal development. Although that is still seen as a critical period, scientists have lately discovered that the epigenome can change in response to the environment throughout an individual’s lifetime.”    Source : Discover magazine DNA Is Not Destiny
