Could the beast tribes all have been artificially created? [3.0 Spoilers]

[myahele]

In the Fractal Continuum we learn that Ixalion (potential predecessors or the ixal) along with other creatures were created by the Allagans

Additionally, we learn that the Poroggo of Sharlayan were "artificially" created via imbuing animals (or frogs in the case of Poroggos) with consciousness through some form of magic. Not only are they intelligent, they're also capable of magic.

Unlike the Alagans who altered creatures on the genetic level, Sharlayan just mearing do it through magic. As such it seems as if it can easily be taken away as stated by one of the Porogos in Motoyas cave.

Since it's not on agenetic level they might not even be capable of reproducing self conscious frogs. There's still so much we don't know about the civilization predating the Allagans, but there does seem to be a trend of the Spoken races experimenting with life.

Is it too far fetch to think that the Warring Tribes of the 1st Astral/Umbral eras created familiars out of animals to fight for them? Just like how the Warring Triad of FF6 created espers to fight in their war?
