Last summer I missed the first incarnation of this story. Hogzilla is a huge wild boar/domestic pig cross shot in Georgia in July 2004. Last night I watched a National Geographic Channel show where they dug this big boy up. They exaggerated the size, he was ONLY 8.5ft (2.6m) long and ~800lb (360kg) My question is this. Some pretty extraordinary claims were made about the reversion of domestic pigs to the wild. They said that if a domestic pig escapes to the wild, within a year or so it will begin to grow hair and its snout will begin to elongate. Its offspring will completely revert to being a wild boar. They did genetic testing on the remains of Hogzilla (had only been buried 6 mos) to find that he was a domestic/ wild cross. What is the the deal with pig genetics that it can apparently change? How is it that a Domestic pig is genetically different from a wild boar, but will very rapidly assume the traits of one when it enters the wild environment? Can anybody shed any light on this for me?
