"Imagine, if you will, a hypothetical world much like our own, but overseen by a mysterious cosmic entity. While our world's rich diversity of life arose naturally through sheer chance, here it would get a head start - thanks to the Observer - with an introduction of a small selection of already-evolved lifeforms from Earth. These introduced organisms would then be allowed to evolve entirely on their own, in isolation, for hundreds of millions of years, until their descendants resembled them barely at all. Now imagine if some of those colonists were highly specialized animals which would never have the means to exploit as many varied niches anywhere else due to competition from other species. Imagine an entire world where the only land animal present is a bird - a world without reptiles, amphibians, or mammals. It would be an experiment in natural selection on a scale never before seen.
This is Serina - the world of birds." Quote by Dylan Bajda on the Serina Home Page
