As humans [[Peopling of the Americas|spread]] to the [[Americas]] in the Late Pleistocene, [[Paleo-Indians]] brought with them related stone tools, which evolved separately from Old World technologies. The [[Clovis point]] is the most widespread example of Late Pleistocene points in the Americas, dating to about 13,000 years ago.

One of the earliest cases of tools comes from the [[Channel Islands (California)]] as it was considered one of the earliest place in North America for civilization. The tools that were found were drills, reamers, scrapers, abraders, spoke-shave, macroblade plane, burin, wood-splitting wedges. These tools show that the eraily civliation were skilled in wood working.

Other tools found from the Channel Islands were crescent-shaped tools that were flaked from heating.<ref>Jew, N. P., & Erlandson, J. M. (2013).

In the [[San Francisco Bay Area]] [[acorn]]s found were often associated with grinding tools. Acorns show diachronic changes in tribal life as the tools used for acorns evolved. Mortar tools like millingstones and [[mortar and pestle]] that grind acorns are seen to be dated in differnt times in the locations.<ref>Buonasera, T.Y. (2013).
