Mutation protection
bacillus:
I think that, in real life as well as DB, these mutations are seldom seen because they are vital, eg. a bot that evolves a cancerous trait or can't feed anymore will, quite naturally, cease to exist in quite a short time frame.

Actually, you see it all over in nature. It's one of the causes of codon bias and long repeat sequences. I.e. Selection has favored coding of our DNA (in conjunction with replication machinery) in a specific way using specific codons and sequences over other synonymous codons and sequences, which by their very nature encode meta-data influencing the mutation probability of those sequences. Many evolutionary biologists think that a large percentage of all mutations may be self-directed in this way by the genome.

So, why don't we add this feature? Everyone here seems to be for it.
Numsgil:
It's mostly a question of "how". There are lots of different ways of doing it, but arriving at a way that pleases everyone has been difficult.

Oh, yeah, I remember reading something like that. "DNA for programmers aka. If you're a hammer, everything looks like a nail" or something like that.

A good method to do this would be to create a sort of secondary DNA exempt from mutations, or using secondary mutation rates. Regular DNA is transferred to this using a command, sort of like creating an internal virus.
