Answer 1

Question is unclear, but here is something from the Internet:

According to both Choctaw oral tradition, and archaeological research, corn was domesticated in Mexico, and then brought northward. It was grown as a minor crop in what is now eastern North America as early as AD 1. However, around AD 1000 a major shift occurred, whereby corn agriculture became by far themost important source of food for Native American communi-ties in the Southeast, including the ancestors of today’s Choctaw.
