The bow and arrow is quite new in the Americas. It was first invented in North America around 500 ad, and was introduced into Mesoamerica by the Chichimec invaders around 1100ad. I am not sure when the South American invented in, or if it was introduced by the Mesoamericans.
The bow was mostly used by the Amazonian tribes. The Inca prefered the ancient atl-atl, but mostly the sling.
