Researchers who have sequenced the genome of a 5,310-year-old corn cob have discovered that the maize grown in central Mexico all those years ago was genetically more similar to modern maize than ...

Genome Sequence of a 5,310-Year-Old Maize Cob Provides Insights into the Early Stages of Maize Domestication. Current Biology, 2016; DOI: 10.1016/j.cub.2016.09.036 ...

Jean Philippe Vielle-Calzada of Mexico’s National Laboratory of Genomics for Biodiversity and his colleagues returned to the caves in Tehuacán Valley where tiny maize cobs were found in the 1960s.

In the first study researchers from the University of Michigan and the Smithsonian Tropical Research Institute in Balboa, reanalyzed maize cobs and sediments that had been excavated in 1966 from ...
