Your DNA is the permanent code you are born with, the code you inherit from your parents. This code is made up of the totality of your parents experience. And your parents genetic experience includes the totality of their parents experience, and so-on and so-on.
As you watch this video, you realize that the genetic code you receive includes chemical tags that attach to your DNA. This means that your biology is looking for, and accepting (or being forced to accept) the experience of your environment in order to evolve and survive. And this experience, is passed down to future generations.
