Final answer:
Africa contributed to human development during the agricultural revolution and the establishment of government by adopting farming techniques, establishing governments and social structures, and utilizing ironworking technology.
Step-by-step explanation:
Africa contributed to human development during the agricultural revolution and the establishment of government in several ways. Firstly, the adoption of farming techniques allowed for the development of sedentary cultures, which in turn led to the establishment of governments, writing systems, and hierarchal social structures. These sophisticated societies were able to build impressive structures, defend their borders, and create art and music. Additionally, Africa's ironworking technology played a significant role in the agricultural revolution by producing stronger tools for farming, enabling the clearing of new areas for settlement and connecting historically isolated regions.
