Guilá Naquitz Cave

Guilá Naquitz Cave in Oaxaca, Mexico, is the site of early domestication of several food crops, including teosinte (an ancestor of maize), squash from the genus Cucurbita, bottle gourds (Lagenaria siceraria), and beans. This site is the location of the earliest known evidence for domestication of any crop on the continent, Cucurbita pepo, as well as the earliest known domestication of maize. Macrofossil evidence for both crops is present in the cave. However, in the case of maize, pollen studies and geographical distribution of modern maize suggests that maize was domesticated in another region of Mexico.
