To leap from the fact that we can recognize design at Mount Rushmore, a noticeably inanimate object, to recognizing design in living creatures is a completely false analogy because an analogy implies something to be similar between the things being compared; there is no similarity between a mouse and a mousetrap.
The situation is even funnier that this.
IDists use Mt Rushmore because they know that we can recognize design, and constrast design with things that are not designed. The faces on Mt Rushmore are designed. But the back of Mt Rushmore is not designed, and neither is the nearby Harvey Peak.
Oops. Reflect on the implications of that.
Humans are usually pretty good at recognizing design. Behe is an exception to this general rule.
