I'm not saying anything about ID. I'm saying human intelligence is a part of nature. Anthropologists work to discover artifacts made by humans, and engineered organisms will eventually be on the list of things studied by anthropologists.
What you are talking about is forensic science.
Sure. But this is a thread about ID. And it just so happens that that "part of nature" is capable of practicing intelligent design. Which leaves you in something of a muddle, no? Because it means you've now got to deal with the possibility of a non-supernatural, and non-naturalistic explanation for biological phenomena.
It is no longer possible for you to stand pat on the "naturalistic" explanation, confident in the assumption that the only alternative is a supernatural explanation. And yet you do just that. Why?
