Originally posted here but since it's largely off topic for that thread, I've decided to create a distinct one.
The Female Changeling has told Odo that once the Changelings were solids but then evolved. Natural evolution in sentient species is basically impossible, so they most likely evolved artificially. In essence, Changelings are super augments of an unknown solid species.
If they are, it's possible that we can see how changeling-solid animosity was actually beginning. In DS9, we see humanity being very biased towards augments, despite the fact that their augmentation is really not that big - they are basically just more smart and strong than average humans but there are no really nature-altering modifications, superpowers etc. The species which the Changelings evolved from may have had the same sort of discrimination and hostility against augments - and the more augmentation, the more intense that hostility was and the more intense was the retaliatory hostility of changelings towards solids.
