The accidental code with an incidental imperative

Intelligent design experts are fond of citing DNA as a core example of irreducible complexity in nature, a code that could not fall together by chance. But evolutionists of done something snazzier than simply insist that it could simply have fallen into place on its own. Once in place, it insisted on its own survival. This is illustrated in the NYTimes latest gee whiz article about natural selection, this time on the importance of beer, perhaps as an antecedent of bread. Cooperative clan activity was necessary to "cooperate, prosper, multiply — and pass along their DNA to later generations." It's a neat trick. After forming itself, creatures programmed by it feel an intrinsic need to pass it on. How a mindless code can perpetuate itself has not been explained. I've never heard of program code, as opposed to programmers, creating more code to perpetuate itself.
