The first Native Americans in North America were hunters who roamed in small bands following their prey.
North America then was the home of many huge beasts, including elephant-like mastodons, great woolly mammoths, and saber-toothed tigers. Humans became adept at chipping stones to make razor-sharp spear points and arrow points that could penetrate the rough hides of these enormous beasts.
In addition to providing people with meat, the animals also gave them warm skins to use for clothing and shelter.
