When did the Andes form?
About 199 million years ago, near the beginning of the Jurassic period, was the time of the dinosaurs. That’s when the supercontinent of Pangaea broke up and the pieces began to float away from each other. The supercontinent split up into the continents we have today.

Human history of the Andes mountains
People first moved into the Andes mountains about 15,000 years ago, when they reached South America. The Norte Chico and Valdivia people went into the Andes early on. Later, it was the Nazca and the Inca. These people domesticated potatoes and tomatoes, so they could spread to other parts of the world. And they started farming tobacco and coca, too. When the Spanish arrived in the 1500s, they took these foods and medicines and spread them all over the world.
