Around 10,000 years ago, corn started as a wild grass called teosinte in Mexico. It looked very different from the corn we know today, with tiny, hard kernels. Ancient farmers noticed some plants had more desirable traits and began selecting and planting these seeds. Over thousands of years, this selective breeding transformed teosinte into larger, softer corn. Today, thanks to modern farming techniques and genetic research, corn is a major food source worldwide, used in everything from food to fuel. The journey of corn shows how human innovation can shape the plants we rely on.
