I don't think that "normal" Agnas originated from Glacial ones. Being used to extreme cold, it wouldn't seem very benificial to adept to an envoirement thats even more extreme(extrem high temperatures as well as less food to prey on, and stronger food rivals). I guess the Agna species has developed at some point in an moderate climate and then the ancestors simply went apart. One part went to the cold Tundra, the other went to the Volcano.
