⚠️ Disputed: the sources disagree.

What it is

Selection of low-toxicity wild Solanum tubers in the highlands around Lake Titicaca, together with the freeze-drying technique (chuño) using frost and sun. A high-altitude crop that feeds dense populations where maize cannot grow.

Remains from Tres Ventanas (Chilca, c. 8000 BCE) and Ancón are disputed; genetics places the origin north of Titicaca around the 6th–4th millennium.

What it led to

  • High-altitude agriculture and the demography of the central Andes
  • Storage of chuño for years, the logistical basis of Tiwanaku and the Inca
  • After 1570, a European demographic revolution driven by the potato
