People often write about particular artists 'evolving' – I'm pretty sure I've done it myself – but a while back I read a nice comment by a science-wise person arcing up against this term usage. Species evolve. Individuals don't. An individual can 'develop' or 'grow' or whatever, but evolution is the process of change across massive populations of lifeforms.
I think that probably holds true for the arts, too. Unless you subscribe to some form of aesthetic creationism that upholds genius as the result of divine intervention. Surprising how much criticism does.
