    Very important lecture and well presened. Recent studies suggest that even the changes of the form and size of beaks of the famous Galapagos finches or Darwin finches are in fact epigenetic adaptation that occurs constantly and does not require hundreds of thousands or millions of years, a couple of years is enough for the changes to happen. And it is not a one-way road, the changes oscillate back and forth, which means they are reversible. Some call it micro evolution, I think the word “adaptation” describes much better this epigenetic process. It is safe to say that much more of what is still thought to be result of evolution a la Neo-Darwinism, needs to be classified as epigenetics.

      Exactly, it is simply adaptation. Any form of evolution implies a linear progression of an organism to a particular environment that is not reversible.

    not only the conversion, change the gene

    I don't like analogies that far off the subject matter. Sure mention them, but move on and explain the actual subject

    I do not see any of these genetic changes she’s talking about.

    The epigenetic changes can have no effect on the sequence of the gene. How can it be used as an argument for evolution, I don't understand. Also, epigenetics is an adaptation mechanism for the changing dynamic environment. Then I think first we should find an answer for how that it can possible to have a forward-thinking mechanism in our body without an intelligent designer behind it? Please don't tell me the answer is evolution because we all agree that evolution theory does not consist of intelligence.
