I'm willing to supply one.
So that Chris can pitch it out? Alllllll rightie then. Odd choice of protest, to my mind.

That's not intolerance, SAM. I toss out all my junk mail, too. There is really no difference.
Well, you win this one, but only because I have no idea what you're referring to, you cunning devil.
I always only come in about halfway. It hurts them too much otherwise.
But as for the thread, how is Hitchens' foot getting in his mouth, you befouled tramp?
Well, if he wants to throw things out windows I have no problem with it, so long as it's not me or doesn't land on me. And I will defend to the point of being uncomfortable his right to do that.
I don't recall objecting to his tone, merely to his using science as a platform for his atheistic aspirations. And his contributions to the meme theory.
Are we talking about the WMDs in Iraq? Or Osama's role in 9/11?
Hitchens is so full of it.
Definitely. Mutation in some systems results in critical failure. Lemme think - if a gene were central to "being" something - a snail, say - then it stands to reason it would be 'insulated' against mutation.
So would I, if he actually went out and did it where it made a difference.
Easy to be a one eyed king in the land of the blind.
SAM:
My bad, I was thinking of amino acids and protein markers.
Anyways, for evolution to occur, all you need is the capacity to self-replicate. I don't think this is limited exactly to the structure of RNA as the molecule involved, but I can't think of some other structure that may be used. For instance, computer viruses can "evolve" in a sense, and they are not organically based.
Ok, that one isn't even connected to the issue. Quotemonger.
GeoffP:
But it's not the genes that are central, it's how they are expressed, no?
Exactly! - epistacy in fixed gene function. A standardized pattern of gene expression that forms the basic blueprint for "snail".

Computer viruses are written, are you saying genes are written?
GeoffP:
Right, there being no specific "snail gene" - just the genes that are actively expressed.
Radiation, to go to what SAM is talking about, would affect the linkage of the DNA chain - there are repair mechanisms, and I suppose there must be a way to speed that process up, but I don't see how that would be able to target a specific gene.
SAM:
No - my point is exactly that they are not, and yet viruses can indeed "evolve."
