 The Development of Agriculture

The development of agriculture about 12,000 years ago changed the way humans lived. They switched from nomadic hunter-gatherer lifestyles to permanent settlements and farming.

 In Mexico, squash cultivation began around 10,000 years ago, but corn (maize) had to wait for natural genetic mutations to be selected for in its wild ancestor, teosinte. While maize-like plants derived from teosinte appear to have been cultivated at least 9,000 years ago, the first directly dated corn cob dates only to around 5,500 years ago.

Purépecha Empire

Mexico

 The Purépecha Empire had many cultural traits completely distinct from those of the Mesoamerican cultural group. It is particularly noteworthy for being among the few Mesoamerican civilizations to use metal for tools, and even weapons.

Due to its relative isolation within Mesoamerica, the Purépecha Empire had many cultural traits completely distinct from those of the Mesoamerican cultural group. It is particularly noteworthy for being among the few Mesoamerican civilizations to use metal for tools and even weapons.
