When trying to explain to someone confused about this casual use of language that seems to imply an intent to evolve, I have used this analogy before.

"Have you ever said something like: I need an alignment done; my car wants to pull to the right? It is clear to the speaker and listener that the car does not want anything, it is just a manner of speech."

"In exactly the same way, when a biologist says 'the finches developed stronger beaks to better crack the nuts found on that island' it doesn't signify intent or design."
