First of all I don't know why you people believe in this fan created rumor when it is so obviously false. If the Zoras are fresh water creatures and when Hyrule was flooded they had to adapt, then wouldn't they just evolve into salt water creatures? which makes more sense:
Fresh water creatures -> Bird like creatures
or
Fresh water creatures -> Salt water creatures

and secondly, I believe that either the kokiri or the deku tree sprouts or deku scrubs did evolve into the korok. It makes more sense for a woodland creature to evolve into a different woodland creature than for a fresh water fish creature to turn into a bird like creature.
