Agriculture began in the Valley of Mexico around 12,000 years ago, where early corn stocks were only about the size of a pinky finger—nothing like the crop we know today. Over 6,000+ years, cultivation spread from Mesoamerica into South America. Interestingly, the Amazon's famous terra preta black soil gardens were man-made, developed over at least 10,000 years by ancient peoples.
