The way Settlers impacted Native Americas in the west was that the US Government forced them to live on land called "Reservations", which may I add wasn't the best lands. Native Americans usually hunted Bison which were their main source of food and clothes, but the US army, railroad companies, and white settlers set out to kill all bison, causing many Indian Americans to starve.
Hope this helps.
Answer:
Neolithic Revolution.
Explanation:
The Neolithic Revolution is a term that refers to the transformation of ancient civilizations from hunter-gatherer societies to societies where people made a living mainly through agriculture and animal husbandry. This is also the change that marked the transition between the older and younger Stone Age. The oldest traces of grain cultivation and animal husbandry are about 11,000 years old, and come from Southwest Asia (the fertile crescent), but an independent development towards agriculture also took place in Central America and China. The term "the Neolithic revolution" refers to the great effect this change had on the organization of the societies that began to cultivate instead of living as hunters and gatherers.
