Well, I tried this once and I guess the mod misunderstood my purpose. My purpose is to discuss this topic, for I know nothing of it and I'm sure people here do (my apologies for wanting help from a certain "group"). This isn't a thread for debate nor arguing, but, rather, suggestions and discussions.
Now, I'm putting this in the form of discussion through AIM for I know nothing of the subject and would like for someone to explain it better for me and, whether or not it's true, for the person who typed it to me has no reliable credentials me to put faith in.
WinAceSE: the thing with evolutionary algorithms is that they can coopt things from entirely different systems and shift the function of those systems
WinAceSE: for example, in my favorite example of irreducible complexity evolving in the lab--the radio from a transistor
WinAceSE: you need 3 components for it to work
WinAceSE: an antenna, relay circuit and oscillator
WinAceSE: and you find it evolved from a bunch of transistors anyway
WinAceSE: "But when they looked more closely they found that, despite producing an oscillating signal, the circuit itself was not actually an oscillator. Instead, it was behaving more like a radio receiver, picking up a signal from a nearby computer and delivering it as an output.
In essence, the evolving circuit had cheated, relaying oscillations generated elsewhere, rather than generating its own."

Strawman,
While brief responses are discouraged here, I'll make one to direct you to an appropriate source for reading up on this: http://www.cogs.susx.ac.uk/users/adrianth/lazwebpag/web/Publications/
After you've read that, look at the "Hardware Evolution" thread on ARN at http://www.arn.org/ubb/ultimatebb.php?ubb=get_topic;f=15;t=000011;p=1
Then maybe you'll have questions that address some of the issues raised by that line of research. Have fun!
RBH
P.S. to the Moderator added in edit: To at least partly mitigate the sin of a short post, I'll point to 1800 words posted in the Karl D. Stephan thread minutes before this one! ![[Smile]](smile.gif)

Dear Strawman,
There are two problems with your thread.
1. Your thread topic is non-descript. If everyone came to our board and simply titled their thread "Please offer some help on this" or "Could someone please answer my question" etc. Then people quickly browsing the discussion would have no idea what your thread was about. Topic titles serve the same purpose as a headline in a newspaper.
2. In your post you note "My purpose is to discuss this topic, for I know nothing of it" Well, when starting a thread it is expected that the user be informed about the topic and be ready to guide the discussion. This is not a general discussion board and though your desire to see discussion around this topic is admirable, you've picked the wrong forum. I'd suggest http://www.arn.org
