My experience has been that the "examples" are simply handwaving and appeals to ignorance and incredulity: they can't imagine how some organism or organ could have evolved, therefore it didn't.

You are putting the cart before the horse. It is evolution which has been claiming for some 150 years that it is true, that it is science. Yet it cannot show the truth of its statements that species evolved gradually all the way from insignificant bacteria to humans. Where is the proof of evolution?

Actually, the notion that humans evolved along a chain that started with bacteria is common descent theory. Common descent theory relies on evolution as its mechanism (with its driving force up for debate with a number of competing theories). Evolution itself is actually much simpler and makes no claim about human origins, it's just about biological populations.
