Out of their gourds

[Hanslune]

This link goes to a discussion on the domestication of squash and why that may have happened and its repercussions.

Quote

Squash (genus Cucurbita), including squashes, pumpkins and gourds, is one of the earliest and most important of plants domesticated in the Americas, along with maize and common bean. The genus includes 12-14 species, at least five of which were domesticated independently, long before European contact in South America, Mesoamerica and Eastern North America.
