After the arrival of Europeans, the lives of the native Americans on the planes changed as they started using horses to hunt bison.
Explanation:
It were the Spanish who introduced horses to the Native Americans. Once the Native Americans learnt horse-riding, they started covering more of land in search of essentials.
The lives of Native Americans became more convenient as now they could travel to distant places in short span of time. This allowed them not only the convenience of locomotion but also the convenience of combat.
