Just a note of reminder here. We are discussing an an analogy and to what extent it's useful in garnering understanding. We all know that anaolgies have this power, but also that they can be thin ice to stand on.
Mijo finds Southwind's anaolgy misleading and useless. He does so because he looks at it through the eyes of ID advocates and responds with what they would say in counter. He's not an IDer himself, he's just measuring the anaolgy against the mind set of IDers and finds it would be unconvincing to them. I think he has shown how problematic it is in that context. Trying to tell an ID advocate that there are no intelligent agents involved in human tool making and technology falls flat.
On the other hand, those of us, and anyone else who understands the "Blind Watchmaker" process of natural selection find Southwind's anaolgy and various forms of it an overarching way to illustrate the evolution of information in diverse systems. Some details that contrast how information is processed in human activity exist, but the target is evolution via Selection.
Furthermore driving the anaolgy calls our attention to the process of selection that underlies even those elements unique to human information processing and cognition. (my "Headless Watchmaker")
The OP's desire to have an overarching vista of evolution is not unique.
Evolution is now an interdisciplinary concept with not just Evolutionary Biology, but Evolutionary Social Science, Evolutionary Economics, and Evolutionary Psychology. Soutwind's anology is by no means a dead end.
With any anaolgy, you consider what will work with your target audience.
With most anyone in this thread, I could mix metaphors in an Adam Smith sort of way and talk about the "Invisible Hand" in Evolutionary Biology.
If I used that phrase most anywhere else, there would be individuals who would thing I meant "God" by saying "Invisible Hand."
But if there was an economist in the room, he'd get the irony. and he might even say, "Looking at it that way, Darwin makes more sense to me now."
So folks, please chill a little. It's just an analogy.
