Dawkins used that example to show that evolution works by cumulative changes, and not by some sudden magnificent burst of outrageously improbable events. In other words, no crocoduck. It's not an example of how intelligence guides evolution, but of how cumulative changes can lead to results that could not happen via completely random forces. Creationists are prone to quote-mining to try and make it seem as if scientists are supporting creation accounts without realizing it, so add this to the pile of dishonest attempts at pretending that there is support for a creator.
"Well, evolution is a theory. It is also a fact. And facts and theories are different things, not rungs in a hierarchy of increasing certainty. Facts are the world's data. Theories are structures of ideas that explain and interpret facts. Facts don't go away when scientists debate rival theories to explain them. Einstein's theory of gravitation replaced Newton's in this century, but apples didn't suspend themselves in midair, pending the outcome. And humans evolved from ape- like ancestors whether they did so by Darwin's proposed mechanism or by some other yet to be discovered."
