[Human] DNA contains approximately 3.2 billion base pairs, about the amount of information that can be stored on a single CD, but only about 5 percent of that information plays a significant role in constructing the human form. Our human CD contains, in effect, the equivalent of one really good, but short, pop song, with the rest of the tracks being staticky hisses, noise, and repetitions of the same short phrase, over and over again
