Granted, people have probably already noticed this and I'm just spouting off old news, but... I was running the Fractal Continuum a while ago with some of my FC mates as part of our Level 60 Roulette. We ran into the Iksalion, and something I noticed that I hadn't before: The Iksalion had almost the exact same model as the Ixal, with the exception of these mobs had wings.

Were the Allagans doing experiments on the beast tribes at one point? Or at least their ancestors?
