Maize (Corn) May Have Been Domesticated In Mexico As Early As 10,000 Years Ago

Maize



The ancestors of maize originally grew wild in Mexico and were radically different from the plant that is now one of the most important crops in the world. While the evidence is clear that maize was first domesticated in Mexico, the time and location of the earliest domestication and dispersal events are still in dispute.





Maize is wind pollinated and sheds large amounts of pollen, which is deposited in soil and water sediments. The tough outer wall (exine) of pollen protects it from deterioration for thousands of years.




Analysis of area sediments revealed phytoliths of domesticated varieties of maize as well as those of agricultural weeds. These data, along with evidence of burning, suggested that agriculturalists were active in that part of the Yucatan Peninsula around 7,000 years ago.


The domestication of maize allowed the creation of food surpluses that drove specialization in culture. In the old world this was done by wheat and in Asia rice.
