Agriculture develops independently in the Americas across three regions

Agriculture in the Americas emerged not once but at least three separate times, with cultivated crops appearing in Mexico and South America as early as 8000 B.C.E. Indigenous farmers domesticated maize, potato, tomato, cacao, and quinoa, and engineered systems like the Three Sisters and Andean terraces. It stands as one of history’s clearest cases of humans independently inventing farming.
