I always think of DNA a lot like programming over the course of millions of years. A strung together series of hackish, barely functioning, uncommented code with no documentation whatsoever. Any reason for why a snippet of code ended up being the way it is has been completely lost to time. All we know is that changing it is bad, certain chunks of code lead to certain behavior, and that the more we look at the code the code spaghetti like it appears.
