Mutations disprove the theory of upward evolution

[Something completely different]

How about a dog growing wings and becoming a flying creature.

Evolution happens through small changes within the genes over an extensive amount of time.

Through those changes an animal can adapt towards the circumstances under which it lives. Which does not mean that the animal becomes a completly different animal. Best example is something called "Ring species":
