The core concept here is the meaning of 'evolved,' which signifies a gradual, natural development over time. Option B accurately describes this process. Option A is incorrect because 'evolved' implies a gradual change, not a sudden creation. Option C is wrong because 'evolved' is about internal transformation rather than external copying. Option D is incorrect as 'evolved' indicates change, not stasis. The key understanding is that 'evolved' denotes a process of gradual change and growth.
