"How did methods of finding food sources affect the cultures that developed in early america?'

thank you sooooo much ;]]

Answer 1

most cultures had to become nomads before they knew how to farm & breed/raise animals.

Most tribes were nomadic, meaning they had to move (follow their food source)  Early asians crossed Beringia (the land bridge) to North America, they were following animals that they hunted for food.
