It was a theory that the Mutos were genetically engineered by the humans. There is a summery on one of the toys that Godzilla was forced to be awakened because "an ancient foe" had risen, and is a threat to his survival. Gareth said that the Kaiju weren't created, they were always here. So the Mutos have been on Earth as long as Godzilla. And that they are natural enemies. The Mutos probably went dormant, as evidenced in one of the TV spots, like encasing themselves in cocoons to survive an event that wiped out the dinosaurs. The humans just found them, and began experimenting on them.
