2.16 Paleoindian Spear Points
Archaeologists have identified the Paleoindians and other prehistoric cultures on the basis of the tools they made, especially their flint spear points and knives. Each culture made its own types of points. Because of this, archaeologists can tell who lived at a given site by looking at the tools found there. By comparing many sites, they can develop an over-all picture of the ways different cultures lived.
