Dude ... lay off the jamaican hotbox showers !!! lol ... i doubt that BPs would "evolve" inside 20-30 generations of captivity, but most certainly would loose their ability to fight of specific bugs found in the wild, and if said cbs were fed F/T continiously through out there lives they could also potentialy loose there desire to hunt or the hunting skills altogether... dont forget it took thousands of years and countless generations to domesticate wolfs into mans best friend lol
