The first agricultural revolution was 11,000 years ago. It was when we first started to domesticate animals. The first crop in the world was wheat. The first crop in America was corn. It changed the way that humans get food because it started farming. Farming is how we now get most of our food. Before farming, humans got food by hunting and moving around while hunting.
This is the first crop ever, called wheat.
