Doubtful. You can to computing with DNA http://dna.caltech.edu but it is still debated if the actual role of DNA is being a code (some recently weasel out form that stance by saying it's an “app”, like there's a difference, machine code being a code). Coding theory applied to DNA yields inconclusive results. Galois theory usually has power over any kind of information encoding, cryptographic, computable or not. One constructed one for DNA convinced mathematicians it's not the way to go at all. If it's computation it's nothing like what we mean by any model computation, you may as well say it's magic instead of making stretched analogies.
About OpenBSD and evolution, that's so fetch... these folk invented the attack in the first place, not evolved a response to some market force in the early oughties. Broadly I don't think designed systems are in business of evolving, otherwise living organisms could perhaps evolved electro-hydrostatic instead of hydraulic power system with a pump being a single point of failure.
