not being at all familiar with Information Theory.... is it a real increase in information, or just seems to be?
I'm no expert either. Shannon-Weaver defined information in terms of entropy. My naive interpretation is that as the message becomes less random (or more ordered) it gains in information.

i'm even less an expert ..... i've read some of that stuff and it made no sense To Me.

(but then, does a Bird ,say, really have more information than a Cricket?)
When it comes to evolution I suppose what is critical is not simply an increase in information but whether new information can be created. So the issue is whether mutation and natural selection can explain the fact that birds and crickets have different information. Off the top of my head, I don't see why not.

i don't know --what's the difference between 'information increase' & 'information creation'?
using your analogy -- you only have to duplicate letters to keep up the 'soup', you don't need to come up with new different letters (if you start with all 26).
Looks like the 4 (?) DNA letters have been around forever ....
