Is Biological Creativity an Example of Picking Your Own Problem?

Is biological creativity an example of picking your own problem? I think yes, probably is my answer. Biological evolution isn't optimizing a single thing but it's going to create wings as a type of locomotion and try that out. But in another sense, always working on exactly the same problem. So we might therefore have a difference between Campbell's theory and possibly there's a difference between Darwin's theory and Popper's theory.
