noooo.. im actually still fairly young (early thirties), just that he was still disputing it for some reason. i think the fox crosses were due to them messing with genes so much, which also made them look very mongrel dog like in every other way, but the sizes suddenly being med dog sizes ans shapes, was what was leading to that conclusion (everything else they thought could be made just by the breeding for fur and tameness, course i would think size might be added bonus, though dogs are already used alot in fur trade). you can breed dolphins with killer whales and alot of others than just those few theyre finding, though a blue whale no... im guessing (i honestly know nothing about dolphins, orchas, porposes, whales etc, ect what com across in hybrid things, aside from maybe basics).
