Corn was first domesticated 9,000 years ago in what is now Mexico. Archaeologists have discovered that people have known about popcorn for thousands of years. In Mexico, for example, remnants of popcorn have been found that date to around 3600 BC.
It is a human invention, a plant that does not exist naturally in the wild. It can only survive if planted and protected by humans. Scientists believe people living in central Mexico developed corn at least 7000 years ago. It was started from a wild grass called teosinte. Teosinte looked very different from our corn today. The kernels were small and were not placed close together like kernels on the husked ear of modern corn.
