What is the first Americans hunt and what happened when that supply of food disappeared?

The first Americans, primarily Paleo-Indians, hunted large game such as mammoths, mastodons, and other megafauna for sustenance. As these large animals became extinct due to overhunting and climate change, the availability of this food source diminished significantly. This shift forced early populations to adapt by diversifying their hunting strategies, incorporating smaller game, fishing, and gathering plant foods, ultimately leading to the development of more complex societies and agricultural practices.
