Washington. Archaeologists affirm that for 3 mil 600 years humans are capable of settling permanently above the 2 mil 500 metros, and they were able to confirm that they did it on the Tibetan plateau, también conocida como la "cima del mundo".
According to research published this Thursday in the American magazine Science, It was thanks to the discovery of barley and wheat, imported fromHalf East, that these farmer-gatherers were able to live at a height of 3 mil 400 metros, since these crops are resistant to cold and high altitudes.
Although there are signs of intermittent human presence on the Tibetan plateau for 20 thousand years, Researchers have determined that it was not until a thousand 600 BC that a group was permanently established beyond the 2 mil 500 Altitude meters.
Archaeologists studied animal bones and teeth (pigs, sheep and cattle), remains of plants and other vestiges from 53 deposits in the northeast of the Tibetan plateau.
Thus, determined that the oldest settlers, does 5 mil 200 years, they lived below the 2 mil 500 meters and depended on crops sensitive to cold.
But signs were found of settlers established above the 2 mil 500 meters ago 3 mil 600 years, whose diet was based on wheat and barley.
"Sobrevivir todo el año a esas altitudes debía ser muy difícil. This raises interesting questions regarding the adaptive capacity of humans., el ganado y de las culturas a tales altitudes", said Professor Martin Jones, from the University of Cambridge in the United Kingdom.
According to him, This discovery could have implications in terms of food security.
