Am I the only one who finds the idea of some corporeal beings evolving into non-corporeal rather stupid? Evolutionary changes happen as an adaptation to the environment. What possible environment conditions would cause this kind of 'evolution', and why wouldn't they cause the same for the neighboring Alpha Quadrant species?

you're right. Evolutionary Theory, whether you believe it or not, does
not work that way. There used to be other theories that taught qualities gained by a living organism count as evolution and could be passed down to its descendants.
I'm no a biologist (engineer), but as I understand Evolutionary Theory, it's simply random genetic mutations that occur in an organism that, if it gives it a better chance to survive/out-compete its fellows, will survive and be passed down, eventually leading to it becoming a dominant trait as it provides an advantage vis-á-vis the non-mutated guys.
And it's not always that predictable to lead to super-beings. Way back, we might have predicted that the next step in evolution would be bigger, stronger, faster dinosaurs. Instead they died out and instead we got not physically imposing dominant creatures but ones with bigger brains. At the time an observer wouldn't have guessed that outcome. So who knows what a next step would be? Whatever it is, it will probably be something unexpected, and certainly won't be anytime soon.
At least, that's according to Evolutionary Theory.
Perhaps there's a different mechanism responsible for turning people into noncorporeal/super beings/demigods/angels/etc. If so, we should call it something other than Evolution. Perhaps either a supernatural cause as in religious systems or something else entirely.
But I agree that, for example, Sisko did not "evolve" into a prophet. He was somehow turned into one.
I like how
flemm referred to them as "transfigured" Bajorans. That nomenclature makes more sense.
And I apologize to those who used the term "evolution". I didn't mean to insult or start an argument. I'm sure you know what you really meant. Sorry for coming across a little harsh. I didn't mean to.

I don't mean to be rude!
