The evolutionary function worked by putting the species in a 1,000 or more years war or something. My guess is the Ultimatrix generated different groups of evolved Vaxasaurians that all went head to head with each other and the one that beat the others were the Vaxasaurians with the shapeshifting cannon arms. The ultimatrix probably just gave each group a random genetic evolution, and one of them was the evolved Vaxasaurian we know about, and picked the one that was best suited, or picked the group that was the winner on the war, and that became Ultimate Humungousaur.
