It starts small, with the animals learning how to speak and revolting against the Farmer. Then they develop organized committees and unspoken leadership. Then they begin to develop rules and conduct meetings, voting on what should be done and how to do it. As two prominent leaders arise, they hold an election to chose one leader for the farm. The pigs begin to separate themselves as the higher ranked officers, more suited to supervising and planning and less for physical labor. Eventually, the pigs are walking on their back legs only and living in the farmer's house, setting up trades with other farms and commanding the other animals.
