Yeah. So, the summary made it sound like evolution happens when new DNA elements occur which activate individual genes, as if you could take a fish cell, feed it the right programming and out would pop a walrus or an eagle. That entire model, though, is wrong -- DNA is not a program being fed into a machine. In many ways, it's both the program and the machine itself. Adding "new DNA elements" is actually the process of adding genes (or, more precisely, adding things which when combined with other parts of the DNA, become genes), which means that you're adding information about how to do something at the same time that you're adding information about when to do something. The verb "activate" does not adequately describe this.
