Talk:Gojira57's Monster Hunter Monster Evolution theory/@comment-28736347-20140916190734/@comment-5020152-20140916203834

Well, according to my own theory, all wyverns share a common ancestor among saurischian dinosaurs, and Piscine and Cave Wyverns (Gigginox and Khezu) are actually hyper-evolved when compared to other wyverns. Piscine Wyverns have gone back to the sea (similar to how whales evolved), and Gigginox and Khezu have evolved to suit an open ecological niche in the darkness of caves. In other words, they're super-specialized wyverns that branched off from the main Flying Wyvern group.
