[MUSIC] We can inherit a lot from our parents. Hair and eye color, height. But we can’t inherit everything, because some biological traits are acquired during our lifetime. The only way to transmit biological information between generations is in the letters of our DNA. But what if it’s not that simple? What if our environment, and our experiences can be passed on to our children and grandchildren? Inheritance is turning out to be much weirder than we think. [MUSIC] Every cell in your body holds an incredible 6 feet (1.8 m) of DNA. The same 6 feet of DNA, each holding identical genetic instructions. Yet when skin cells regenerate every day, the new ones somehow “know” to become skin cells, not bone, or muscle. Something beyond just DNA influences...
