  Mesoamerica would deserve its place in the human pantheon if its inhabitants had only created maize, in terms of harvest weight the world's most important crop. But the inhabitants of Mexico and northern Central America also developed tomatoes, now basic to Italian cuisine; peppers, essential to Thai and Indian food; all the world's squashes (except for a few domesticated in the United States); and many of the beans on dinner plates around the world. One writer estimated these indigenous tribes developed three-fifths of the crops now grown in cultivation, most of them in Mesoamerica. Having secured their food supply, the Mesoamerican societies turned to intellectual pursuits. In a millennium or less, a comparatively short time, they invented their own writing, astronomy and mathematics, including the zero.
  
  Maize played an important role in Mesoamerican feasts due to its symbolic meaning and abundance. Gods were praised and named after.
  
  Companion planting was practiced in various forms by the indigenous peoples of the Americas. They domesticated squash 8,000 to 10,000 years ago, then maize, then common beans, forming the Three Sisters agricultural technique. The cornstalk served as a trellis for the beans to climb, and the beans fixed nitrogen, benefitting the maize.
  
  Fray Bernardino de Sahagún collected extensive information on plants, animals, soil types, among other matters from native informants in Book 11, The Earthly Things, of the twelve-volume General History of the Things of New Spain, known as the Florentine Codex, compiled in the third quarter of the sixteenth century. Bernardino de Sahagún reported the ritualistic use of Psilocybe mushrooms known to the Aztecs as teōnanācatl (agglutinative form of teōtl (god, sacred) and nanācatl (mushroom) in Náhuatl). An earlier work, the Badianus Manuscript or Libellus de Medicinalibus Indorum Herbis is another Aztec codex with written text and illustrations collected from the indigenous viewpoint. The ancient Aztecs used a variety of entheogens within their society.
  
  Evidence shows that wild animals were captured and traded for symbolic and ritual purposes.
