Can changes in DNA explain evolution?

From the video description:

"Molecular biologist Douglas Axe challenges the idea that one can evolve major new life forms simply by mutating DNA. In his words: 'There is no reason to think that one can modify fundamentally the form of life by changing DNA.'"


The concepts behind the theory of Neo-Darwinian evolution are predicated on the idea that small, random changes during the early developmental phase of organisms can produce mutations that will be either beneficial or harmful to the organism, but ultimately will be decided upon by process of "natural selection". But before natural selection can even begin to occur, the changes in the upstream developmental process have to take place to allow natural selection to do its thing. But is this even possible? In Darwin's time he had no idea about the DNA and the role that it plays in cell development. So knowing what we know thus far though, can lifeforms be significantly altered by modifying the DNA code? Listen to what Dr. Doug Axe, a molecular biologist and an expert in this field of research, has to say.
