For many years molecular biologists have been mystified by the fact that very little of an organism's 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_DNA.H

*

* Human Genome

* Version 2.1

* (C) God

/* Revision history:

*

* 0000-00-01 00:00  1.0  Adam.

* 0000-00-02 10:00  1.1  Eve.

* 0000-00-03 02:11  1.2  Added penis code to male version. A bit 

*                        messy. Will require a rewrite later on 

*                        to make it neater.

* 0017-03-12 03:14  1.3  Added extra sex drive to male.h; took 

*                        code from elephant-dna.c

* 0145-10-03 16:33  1.4  Removed tail.

* 1115-00-31 17:20  1.5  Shortened forearms, expanded brain case.

* 2091-08-20 13:56  1.6  Opposable thumbs added to hand() routine.

* 2501-04-09 14:04  1.7  Minor cosmetic improvements -- skin colour

*                        made darker to match my own image.

* 2909-07-12 02:21  1.8  Dentition inadequate; added extra 'wisdom' 

*                        teeth. Must remember to make mouth bigger 

*                        to compensate.

* 4501-12-31 14:18  1.9  Increase average height.

* 5533-02-12 17:09  2.0  Added gay option, triggered by high 

*                        population density, to try and slow the 

*                        overpopulation problem.

* 6004-11-04 16:11  2.1  Made forefinger narrower to fit hole in 

*                        centre of CD.
