Final answer:
American colonists developed governance systems that differed from the English ones by establishing local assemblies and representative bodies.
Step-by-step explanation:
In the development of governance systems in the American colonies, they began to differ from the English ones by establishing local assemblies and representative bodies. While the English system was based on hereditary monarchy and replication of the parliamentary model, the American colonists embraced the idea of self-government and representative democracy. Each colony developed its own governmental structures, resembling the British system with a governor, an upper house, and a lower house. Additionally, the colonists believed in their rights as British citizens and the ability to protest against objectionable policies and laws.
