Abstract:
In a new study, DNA from a 5,310-year-old corn cob found in the Tehuacán Valley in Mexico was sequenced and compared to modern maize and its wild progenitor grasses. The sample was found to be an intermediate between modern maize and its wild relatives, suggesting a gradual, protracted domestication process.
