A very long and bitter scientific feud over one of the world's most important food crops, ordinary corn, has finally been resolved, scientists reported.
Now they know, approximately, where corn came from.
Recent discoveries based on gene-reading technology have finally ended this often rancorous conflict. The verdict: Corn's direct ancestor is a weedy type of grass called teosinte, which can still be found growing wild in Mexico.
These new conclusions are based on the discovery of very old corncobs recently in a cave near Oaxaca, Mexico, by researchers from the Smithsonian Institution, Texas Wesleyan University, and the University of Michigan.
