To answer your question, I say a design is intelligent, for as long as that design exists without someone being able to give some other CLEAR and exact explanation for how it came to be.
Until that happens, it is intelligent in origin.
Well, it just so happens you are very fortunate, because there is a clear and exact explanation - it's called the Theory of Evolution.
Why don't you read some books on the subject (written by evolutionary biologists who have constructed the theory, and not by creationists) and then come back with some intelligent questions about anything you may not understand?
