In a New Scientist article a while back there was an article on "evolving" an electrical circuit to perform a particular task. The experiment had worked but the result was not a human design - in fact it was quite hard to comprehend since it had apparently used side effects of the presence of some components as an essential part of the design.
This isn't the article but I think it refers to the same study you are talking about.
