It may have been possible that through nature if we had left our bees untreated that we would of had natural selection or at least hope there would of been or else there would be no bees period. don't forget that varroa is an unatural parasite to the european honey bee, it's been only the last 15 years here anyway that we had to take measures to control the mites. Now, if i didn't start treating at this time i know i would of lost all if not most of my hives and that would probably still happen today. Tell me, if even 65% of everything we eat is due to the direct pollenation of the honeybee, how would we, at that time let the number of hives in north america get to a devestating low in order to aquire genes that are now starting to become active and nurtured. You would of though that something of a mite resistant bee would of come out of europe already too, but i see there still treating over there too. but i reckon it wasn't worth it to them "beekeepers and growers who need pollenation" to let most of the bees die in order to get those few hive that might survive, that might have a gene to be resistant to the mite. It is sad that we ever treated for mites. we never should of had to.
