Maize Cultivation in Tehuacán Valley

Maize (aka Corn) cultivation in the Tehuacán Valley of the central Mexican state of Puebla, showed up around 2700 BCE. The date was found by using an accelerator mass spectrometer and evidence presented in 1995. Mind you Maize did not become a major food source for about another thousand years, after it introduction to cultivation.

  • The earliest archaeological maize (Zea mays L.) from highland Mexico: New accelerator mass spectrometry dates and their implications
    Accelerator mass spectrometry age determinations of maize cobs (Zea mays L.) from Guilá Naquitz Cave in Oaxaca, Mexico, produced dates of 5,400 carbon-14 years before the present (about 6,250 calendar years ago), making those cobs the oldest in the Americas.
