For many years molecular biologists have been mystified by the fact that very little of an organisms DNA seems to serve any useful function. I have solved the mystery. The reason why only 30% of human DNA performs any useful function is that the rest of it is comments. Once we decode a typical human genome, we see that the contents begin as follows:
* Human Genome
