Yes!!! someone with common sense! I agree that the Zora could not have evolved into the Rito in any way. The point you made about WW coming only 100 years after OoT which would not be enough time for the Zoras to become Rito was spot on. It just makes no sense that the Zoras could evolve into the Rito even in 1,000,000 years. And if they were the decendents of the Zora then why would they live on a volcano? that makes no sense. I personaly think that they didn't evolve from any other main race and instead maybe the Rito are a new race altogether. *Gasp* (Rito evolved from the shiekah? that doesn't make any sense either)
There has been an argument made by many people saying that the Zora are a fresh water race and would not survive in the salt water of the sea, which would explain why they don't seem to live in the Great Sea. But I think that it would make much more sense for the Zora to evolve into a saltwater race than into a bird!
In the end I think that Nintendo wanted to introduce some new races without them being overshadowed by the main races from OoT; for all we know the kokiri are gone, the zora are gone, and the goron have moved somewhere else and few of them visit he Great sea over Hyrule just as merchants. The only thing I am unsure of is where the Rito came from and why are they now a main race.

and what real evidence is there that says the Zora evolved into the Rito?
