Mississippi Plain and the eastern coast of North America, now the Eastern United States. Bean cultivation arrives from Mexico, much later than in Mexico due to the barrier of North America’s deserts. And even later than in Eurasia. Thus, the Mexican trinity of corn, beans, and squash is completed, allowing the Mississippi population to experience a population boom, the so-called Mississippi Florescence. It should be noted, however, that these crops are not even remotely comparable to the yield and nutritional value of wheat and barley, and nuts and fiber are completely lacking, as are draft animals of any kind (except for sled dogs in the Arctic regions of North America, but not in Mississippi).
