As an offering of a palm (no, not a psalm), I suggest that we start naming evolution "intelligent design".
That is to say, things that evolved as they did over a long period of time, relative to nature's mysterious (but very rigorous) processes.
Yes there is a designer. It is called space, time, circumstance, conditions, etc. or in shorthand; evolution. An impersonal force.
So what is unintelligent design then?
Somebody more technically versed than me will have to draw up the full charter, but I can give an example: Monsanto's "Round Up Ready" soy beans.
That is to say, genetically modified organisms that are being let loose in nature with unforseeable consequences.
