Mississippi Plain and eastern coast of North America, now the Eastern United States. Domestication of plants such as sunflowers, also understood as the selection of the most suitable species and thus the involuntary genetic modification of the species, begins, but domesticated animals are completely absent. Horses and other large mammals have completely disappeared, perhaps due to extermination by humans thousands of years earlier. Agriculture, however, allows human groups to form villages, generate surpluses to support non-productive jobs, larger populations, support complex organizations, and have writing, technology, armies, and religion. So it makes a difference compared to before. But America arrived several thousand years after Eurasia in this regard, and furthermore, agricultural crop yields are not the same, and on a continent with enormous geographical barriers to the diffusion of knowledge, Eurasia also has sheep, horses, donkeys, cows, and pigs. This will make a difference when the two cultures come into contact.
