i said gigginox is the "evolution" in the way of being much more adapted to it's habitat and further from it's regular flying wyverns ancestors than khezu. still, remember evolution is caused by random gene mutations and as long as they don't compete for food in the same region there's no reason for khezu being replaced by gigginox.
