Yes, those evolution triggers that are impossible to achieve in this game were set to stones. For trade evolutions you'll need link stones (both only trade and trade while holding items). You can find some or buy them in Nightshade. I'm not aware if there's any more changes, probably for those new Gen VI evolutions there will be,  but the Location triggers are all ingame. Magnozone & Nosepad in the Omoth Power Plant (west), Eevee in the frozen north or birch forest (east).
