It'd be more correct to say that the codes are still being decoded, but I see we're talking past each other again. I was talking about genetic programming, not genetic engineering.
I took a look at the article you linked. Tough reading (too technical, not enough explanation) but I got the gist of it. Here's my guess. As we understand more and more of the genome we'll see more and more complexity, more and more mechanism, cycles impinging on cycles in crazy ways. That is not a hallmark of design at least as practiced by humans.
But that's just a guess. Time will tell.
Have you ever analyzed a memory dump(of a computer)? Without any knowledge of what is going on it is practically senseless. But with knowledge and practiced patience you can pick out different languages, data types, data in transition, reserved areas, a complete hodge-podge of information. This from a computer that is doing something.
