Because of this new thread, I am bumping this one. My requests for definitions have not been satisfied a ...[text shortened]... mation can or cannot increase in the absence of intelligent intervention is without any support.[/b]
Sorry if this has already been said, it is a long thread and I am feeling lazy but from your saying neither position has any support I will assume it hasn't been said yet:
Information most certainly CAN increase in the absence of intelligent intervention.
First, for the purposes of this question I define information as any genetic material that is in a functional part of the genome, either coding or regulating. There is a lot of junk DNA which does nothing, if that were to become active through a mutation, I would regard that as an increase in information. Genetic mutations can increase, decrease, and change the information of your genome.
I defend this definition with the fact that a change to something's functional genome will often, but not always (the genetic code is degenerate, multiple sequences code for the same amino acid) result in some change in the organism, large or small. Actually, I am adding that something only constitutes a change in information if it changes the function in some way, silent mutations don't count.
So under this definition, information can be added in many ways.
A cell's transcription machinery can make a mistake, causing a mutation when they copy the DNA. Base pairs can either be substituted, deleted, or new ones added.
Retroviruses insert their genetic material into the genome, this could itself be considered a gain of information, but a defective virus is even better because it will most likely not encode anything that will make a virus and kill the cell.
So your cells can either add information to themselves by accident, or viruses, which most scientists do not consider alive, and are certainly not intelligent, can add information to a cell.
