Late to this interesting thread.

Haven't there been a few programs that have tried use evolution and other biological characteristics as a way to achieve artificial intelligence? One I remember is Tierra, website here:

http://www.his.atr.jp/~ray/tierra/

the purpose of which is "to use evolution by natural selection in a medium of the digital computer to generate complex and intelligent software." Eventually, the "organisms" in this software achieve a sort of "social" awareness.

Or from Wikipedia: "The basic Tierra model has been used to experimentally explore in silico the basic processes of evolutionary and ecological dynamics. Processes such as the dynamics of punctuated equilibrium, host-parasite co-evolution and density dependent natural selection are amenable to investigation within the Tierra framework."

That I can tell Tierra was a failure in general, though there are some specific success stories. That I can find there was no final report produced for the Distributed Tierra experiment. Last time I checked Ray had moved on from ALife specifically to analyzing brain function.
