What were three ways the lifestyle of the Indian people changed even before they met the white people?

Before encountering white settlers, the lifestyle of Indian people changed significantly due to factors such as the introduction of new agricultural practices, which led to the cultivation of different crops and a shift in food sources. Additionally, the development of trade networks allowed for the exchange of goods, ideas, and technologies among tribes, fostering cultural diversity. Lastly, intertribal conflicts and alliances influenced social structures and territorial boundaries, reshaping their communities even before European contact.
