It looks to me like semiosis, as used by creationists, is just numerology without the numbers.
I think that it has more to do with information. What they are saying is their puppet master is behind the scenes giving molecules the information to react to physical laws...the invisible creator at last!
My point was that in both semiosis and numerology the "meaning" is assigned by the believer. It is not necessarily inherent in the system.
What is meaningful to a creationist trying to "prove" that God exists is not the same as what is meaningful to a DNA molecule trying to replicate itself. (The DNA molecule has a much simpler agenda. )
