The Ghost in Your Genes
BBC Horizon Documentary

"The conventional view is that DNA carries all our heritable information and that nothing an individual does in their lifetime will be biologically passed to their children. To many scientists, epigenetics amounts to a heresy, calling into question the accepted view of the DNA sequence a cornerstone on which modern biology sits.

Epigenetics adds a whole new layer to genes beyond the DNA. It proposes a control system of 'switches' that turn genes on or off and suggests that things people experience, like nutrition and stress, can control these switches and cause heritable effects in humans."
