For centuries and millennia, they were wild. They grow from bushes, underground. They have spread to all countries in South America. They are that staple of going-to-school dishes.
Peanuts, of a domestic nature, are a new phenomenon, by the context of millennia and the evolution of plants. Scientists believe that the domestic peanut plant that we see today was a result of a hybridization of two wild peanut species, creating what was the first peanut bush that was edible.
The start of this is thought to be locations: Southern Bolivia or Argentina. But soon they’d spread–to Peru, Ecuador, Brazil, Uruguay. Croppers would plant them in Central America and the United States. People would snack on them, from the Middle East to Southeast Asia. From East Africa to Europe. And then the United States.
