The Mesolithic Age occurred between 10,000-8,000 BCE. During this time, humans moved out of caves and began building huts. They invented new stone tools like bows and arrows for hunting and boats for fishing. Humans also began domesticating wolves, which eventually became dogs. Societies grew larger and people started making pottery and jewelry. However, humans still maintained a nomadic lifestyle, hunting and gathering food and then migrating to new areas once resources were depleted.
