Here is a gem for you:
The idea of nanotechnology is founded in the premise that it will be possible to construct machines with atomic scale precision (Feynman, 1961; Drexler, 1981; Drexler, 1986). Biology provides many examples that this is possible; we “merely” need to learn what has been achieved by evolution and copy it. But eventually we must determine what the engineering limitations of molecular machines are. [emphasis mine]
Here are some examples of scientists attempting to emulate the engineering marvels of ID (Oops! I meant EVOLUTION):
I am wondering why evolution has not already produced a bacterial propeller such as the one engineered by the intelligent folks at Cornell.
