Nature vs. Nurture

LiveScience discusses nature vs. nurture in an article that shows that influences like toxin exposure to physical affection can influence our genes via epigenetics. These gene expressions are sometime dynamic and reversible. It lasts only while the changed environment exists. We know our DNA is not much different from monkeys or other mammals. It is not our DNA that makes us human but how our epigenetics “plays” our DNA. We are the sum of the environmental; effects on us.
