Epigenetics is the study, in the field of genetics, of cellular and physiological phenotypic trait variations that are caused by external or environmental factors that switch genes on and off and affect how cells read genes instead of being caused by changes in the DNA sequence. In layman's terms, you inherit more than the basic genetic component from your parents, you also inherit the memories, the experiences, the phobias and loves, the feelings, of our ancestors. In the DNA you inherit from your parents, some DNA material is switched on, others switched off. The geneticists are still researching how this happens. But... when you stand on the land your ancestors lived for centuries and you have that feeling of recognition and familiarity with the land, the sky, the location, there is more going on than you think. Your ancestors are communicating with you.
