Stone needles grinded 8000 years ago were found in Tibet. What new discoveries have been made in this prehistoric site?

The Qinghai-Tibet Plateau is called the roof of the world, and it is also called the third level in the world, because its climate change is too sensitive and too fast, which makes it impossible to prevent. Eight thousand years ago, the earth was in a warm period of overall warming, which provided conditions for primitive humans to settle and live in such a high altitude area. In other words, the climate of the Qinghai-Tibet Plateau 8,000 years ago was much milder than it is now, with better vegetation, temperature and humidity, which is suitable for long-term human settlement. Recently, a joint archaeological team composed of Sichuan University and Tibet Institute of Cultural Relics Protection found a bone needle ground by prehistoric humans in Tibet 8,000 years ago near a small lake called Siyucuo, 40 kilometers west of Ritu County, Ali Prefecture, western Tibet. This discovery shocked the world, and the small hole for threading on the bone needle was clearly visible.

As early as1April 1992, archaeologists collected 92 stone tools used by prehistoric humans, including the hand axe of Paleolithic age, near Danshuicuo, which is more than 4,300 meters above sea level. In view of the limited conditions, there was no deep excavation exploration for its soil layer at that time. Archaeologists have been making unremitting archaeological explorations here. 20 19 they found the original accumulation layer black soil layer here. The reason why this soil layer turns black is mainly because it contains burning ash and carbon particles left by prehistoric people with fire.

The joint archaeological team excavated 49 square meters of soil, and was surprised to find 10 remains of human life and 1835 stone products, among which the microliths represented by bone needles really shocked archaeologists. In addition, they also found the bones of 1300 animals here. According to carbon 14, the site dates from 8500 to 7500 years ago, belonging to the early new era. Experts concluded that humans had settled here at that time, and there is still no evidence to prove this inference.

To the excitement of the archaeological team, the earliest perforated stone needle used to grind stone tools on the Qinghai-Tibet Plateau was found by the lake. Although the Qinghai-Tibet Plateau caught up with the warm period of the earth at that time, the temperature difference was much smaller than now, and the natural living environment was better than now, after all, the Qinghai-Tibet Plateau was the roof of the world, and it was too cold on it, so primitive people still needed to sew clothes with stone needles to keep out the cold. The site of April CuO became the earliest prehistoric site in western Tibet. Its discovery not only makes up for the shortage of prehistoric archaeology and prehistory in Tibet, but also has extraordinary research value in geology, climate and biology. I can't help but marvel after reading it. The Qinghai-Tibet Plateau is so friendly and lovely!
