The genetic code of the people of the Qinghai-Tibet Plateau was deciphered by the ancient spine of the Chinese Academy of Sciences

Science and Technology Daily (Reporter Tang Wei) What is the genetic link between the ancient population of the Qinghai-Tibet Plateau? What kind of genetic contribution did the ancient people make to the Tibetan people living today? In order to find out,
team of the ancient spine paid for a number of units, from 5200 years from the Qinghai-Tibet Plateau population mitochondrial genome research. The findings were published online in the Proceedings of the Royal Society B.
, the researchers analyzed the mitochondrial genomes of 67 ancient Qinghai-Tibet Plateau populations by region and altitude into low-altitude groups (LTPs) on the northeast edge of the Qinghai-Tibet Plateau and high-altitude groups (HTPs) on the Qinghai-Tibet Plateau. The results showed that there was a direct maternal genetic link between the two groups.
Previous research has pointed out that barley, a cold-resistant crop from about 4,000 years ago, was admitted as the main crop on the northeast edge of the Qinghai-Tibet Plateau and was accepted as the main crop in 3600 years ago, which is why ancient people were able to settle in most areas above 2,500 meters above sea level.
assuming that the agricultural spread from LTP to HTP is caused by mass migration, the researchers expect to be able to observe more single-mass amplification, but they have not actually observed it. It is indicated that the representative groups of low-altitude populations have not increased significantly at high altitudes, meaning that settlements brought about by local agriculture are more likely to be the result of the spread of technology than of mass migration.
, what is the genetic relationship between the Tibetan people living today and the people of the ancient Qinghai-Tibet Plateau? Fu Qiaomei introduced, in comparison with the modern population found that the ancient Qinghai-Tibet Plateau people and the Tibetan people living today have a closer matrihood genetic link.
