Also, the Zora's supposedly "evolved" into Ritos. Well, this doesn't make much sense to me at all. By Natural Selection, the Zora's would survive the flood and thrive, as they are adapted to the ocean environment. But no, bird-like traits are selected for. To make matters worse, they are given wings. How much more backwards can the ecology of Hyrule be?
Well there are a few arguments for this.
For one, there's the whole argument about "Sea vs River Zoras". Generally the noble and civilised Zora tribe that we know live in secluded areas of water -- rivers, bays, ponds etcetera. Having them exposed to the vast oceans could mean multiple negative impacts that could hinder there chances of survival. For one water salinity is much higher in oceans, the original Zoras thrive off a different source of water, just a slight change could hinder there prospects of survival. Also they would have to become dominant, having a secluded area meant safety, now they would be fighting for survival with many water based creatures.
There is also an argument about Zoras not being allowed to thrive in the oceans as they could expose the secret about, the now sunken, Hyrule. It's a weak argument in my opinion but it could be somewhat applied. I also feel that because of the Great Sea now secluding one location from the next -- separatarion of Islands -- that they now needed to have an efficient way of communicating. Since Zoras typically had such traits, maybe they where the only suitable and civilised race that could make that transition. This they became the Rito and the Great Sea's postal service.
I'm gonna go with
Hylia here, something just doesn't sit right with me. Who exactly is she, we know she's a Goddess but what properties does she possess? Her main purpose was to "watch over" the Triforce but this isn't exactly a role akin to a God like figure, this role has been adopted by Kings and such down the line -- so overall not that important.
My main problem though is that where exactly did she come from? Was she an original being like the Golden Goddesses? Or was she created by them and ordered to watch over the Triforce?
