A new study suggests early Tibetans' ability to grow barley enabled them to establish permanent settlements at such an extreme altitude in the Himalayas, the Business Standard reports.
Barley agriculture could provide people enough food supplies even during winter, as barley is frost hardy and cold tolerant, it grows very well on the Tibetan Plateau even today, researchers said.

Researchers examined pottery, stone artefacts, animal bones, charred plant remains and other signs of human habitation from 53 sites across the northeastern Tibetan Plateau to learn how humans managed to live at high altitudes.
The study by the McDonald Institute of Archaeological Research at the University of Cambridge found evidence of periodic human presence as far as 20,000 years ago.
They also found signs that around 5200 years ago, people started to establish year-round settlements at up to 2500 meters above sea level with the early settlers depending on millet, a frost-sensitive grain long planted across northern China that would not have thrived at higher altitudes.
However, about 3600 years ago, people started making permanent settlement at higher altitudes reaching over 3000 meters above sea level and this happened after barley was introduced to the settlers of this region.
