How Did Humans Invent Corn?

The corn you eat every day does not exist in nature. It never has. So where did it actually come from? Modern corn was built by hand, from a useless wild grass, over ten thousand years — without any knowledge of genetics. And the forgotten processing method that went with it caused one of the deadliest epidemics in American history. • Corn's wild ancestor, teosinte, looks nothing like corn — and for a long time, scientists refused to believe they were even related • A Nobel Prize-winning geneticist proved that just five genetic changes separate a weedy Mexican grass from the crop that now feeds billions • The Maya built an entire civilization on corn — and encoded the secret to eating it safely into a daily ritual most of the world eventually forgot • When Europeans spread corn across Africa, Asia, and the American South without that ritual, over three million Americans developed a devastating disease called pellagra • A US Public Health doctor named Joseph Goldberger figured out the truth decades before anyone believed him — and died before he was vindicated • In 1970, a single fungus wiped out 15 percent of the entire American corn crop in one summer — because nearly every plant in the country shared one hidden genetic weakness • The wild ancestors of corn are quietly disappearing in the same Mexican mountains where it was born — at the exact moment we need them most Information in this video is for educational purposes only.
