By what year did American farming, specifically corn, beans, and squash, emerge in Mexico and Central America?

The emergence of American farming, particularly involving the cultivation of corn, beans, and squash, traces back to approximately 6500 BC in Mexico and Central America. This timeline marks a significant development in agricultural practices, which laid the foundation for complex societies in these regions.

The trio of crops, often referred to as the "Three Sisters," became staples in Mesoamerican diets and contributed to the establishment of sedentary agricultural communities. The domestication of these plants provided reliable food sources, enabling populations to grow and societies to develop distinct cultural identities.

Recognizing this timeline is crucial in understanding the evolution of agriculture in the Americas and its impact on societal developments. The cultivation of these crops represents an early instance of humans manipulating their environment to improve food security, leading to advancements in technology, trade, and social structure.
