Ancient People Carried a Wild Potato Across the American Southwest 10,000 Years Ago
A new study reveals an amazing story. Ancient Indigenous people carried a wild potato across the American Southwest. They did this more than 10,000 years ago.This action helped the plant spread far and wide. As a result, these communities shaped the potato’s future long before farming began.
Meet the Four Corners Potato
The plant is called the Four Corners potato. Its scientific name is Solanum jamesii. This small, hardy potato still grows in the region today.It is a wild ancestor of modern potatoes. The potato is also very nutritious. Ancient people valued it for food and medicine.
Evidence from Ancient Tool
Researchers examined old stone tools. These tools came from 14 archaeological sites. They tested them for tiny starch granules.They found potato starch on tools from nine sites. Some starch was incredibly old, dating back 10,900 years. Most sites were near the potato’s modern northern range.
Genetic Clues Support the Story
Previous genetic research adds proof. Some potato populations in the north have southern origins. This strongly suggests people moved the plant.Therefore, ancient travelers extended its natural range. They brought it into areas like Utah and Colorado.
