how was the corn plant saved from extinction in 1970

Between 10,000 and 13,000 years ago, scientists reasoned, farmers had selected and planted the seeds with favorable traits and over time the plant was transformed. election year, and while a few congressmen and senators made inquiries "The USA in Botanists have debated for nearly a century over the origin of corn, believing at one point that the modern plant was descended from an extinct wild maize, or something yet undiscovered.
