Below are the best videos we could find on Epigenetics.
Epigenetics is the study of gene expression and the way genes respond to behaviors and environment. This field developed in recognition of the fact that though our DNA itself does not change over our lifetime, the way our bodies read our DNA does. Lifestyle factors—such as nutrition, behavior, stress, physical activity, and work habits—and signals from our physical environment can have deep implications in gene expression, which can in turn affect the genes we pass on to our descendants.
