Origins of the Potato

The potato (Solanum tuberosum) is believed to have been first domesticated in the Andean region of South America, particularly in present-day Peru and northwest Bolivia, around 7,000–10,000 years ago. Archaeological evidence suggests that indigenous peoples cultivated and selectively bred wild potato species to develop the varieties we know today.

Botanical Background

Potatoes belong to the nightshade family (Solanaceae), which includes other important crops like tomatoes, peppers, and eggplants. The wild ancestors of the potato thrived in the high-altitude, cool climates of the Andes, adapting to harsh conditions that shaped their genetic diversity.

Are Potatoes Native to America?
