The physical changes that pigs undergoe while changing from domestic to feral within the same pigs life is what I have been searching for on the internet for a long time now and I can't find anything. Does anyone have a source to site or any information links etc? I haven't been able to find out this information anywhere. Specifically: I don't care about changes over the course of many generations of pigs ; I mean the physical transformations that take place when a single pig goes feral within days or weeks or months of escaping captivity. These changes were mentioned in two documentaries on Discovery Channel about Pigs called Pig Bomb and Hogzilla. I haven't been able to dig anything up on this since.
