Problems with Chromosomal Evolution - From Circular to Linear

Just to clarify for Nosy, we used to have this guy here who would exessively and dishonestly redact his posts after people had responded to the things he had deleted. It's ok for you to edit after the fact to reflect things you've learned, and I think the way you did it was ok (but I'm no admin), but it's probably best that your original text survive in some form, as people might have responded to it already.Nosy's message might have been a bit perfunctory, and I think he's nervous about redacting opening posts because, as I said, there was this guy here who we had big problems with. He's not trying to bring the hammer down, I'm sure; just trying to prevent that problem from happening again, because it was kind of a big deal at the time.

Are you sure about that? It seems to me that since all enzymes do is reduce the activation energy of certain chemical reactions, there could easily be a complexity gradient - i.e. you might have two enzymes with active binding sites for the same molecules, but one of them is able to catalyze the reaction at a lower activation energy than the other.

Right, but that's a lot less of a hurdle than you made it out to be if there's varying levels of functionality.
