How did paleolithic hominids colonize the plateau?Here we Go declassified the Daocheng Piluo Ruins
As far back as the Paleolithic age, ancient people used percussion techniques to make tools.Stone tools are the key that ancestors left for modern people to explore ancient times.The Piluo site, a rare paleolithic wilderness site, was discovered in 2020 on the southeastern edge of the Qinghai-Tibet Plateau at an altitude of 3,750 meters.What kind of stone tools did the archaeologists find here?Why does it attract attention?In the latest episode of CCTV’s “Let’s Talk” program, archaeologist Gao Xing, a researcher at the Institute of Vertebrate Paleontology and Paleoanthropology of the Chinese Academy of Sciences, and Zheng Zhexuan, the deputy director of the Institute of Archaeology of the Sichuan Institute of Cultural Relics and Archaeology, and the executive leader of the Piluo Site archaeology, brought a lively public lesson on archaeology.”If I were an ancient human, I would definitely come to Pyro to live.”Jeong cheol-hyeon recalled the discovery of piluo ruins.In Tibetan, Pilo means open ground where two rivers meet.Surrounded by water on three sides and mountains on one side, it is very striking.On May 11, 2020, the team found a small number of stone cores on the day of the expedition to Pilo. The next day, they found the first very typical hand axe, then the second, the third…”On the fourth day, something really powerful happened.”Zheng said there were many stone tools exposed on the ground in an area the team collected.”We were all in a bit of a frenzy, feeling like our backs were bent all the time. One of us just stood up and the other was bent again.”Since then, Piluo site began to actively excavate, after more than seven months of work, the archaeological team unearthed more than 7,000 pieces of stone tools in the strata, including the part collected on the surface, the total number of more than 10,000 pieces.”It was very informative and very surprising.”The hand axe found at Pilo site is undoubtedly a great addition to paleolithic archaeology.The acheulian technology remains with the highest altitude in the world, abundant in quantity and clear stratum and age have been excavated here. The stone products such as hand axe and thin blade axe unearthed are the acheulian combination with the most typical shape, the most exquisite production, the most mature technology and the most complete combination in East Asia.Gao xing believes that the Acheulian technological remains unearthed at pilo erased the “Movis line”.This further shows that the building of a community with a shared future for mankind began at an early age.”With Pilo, we can connect some sites with hand axes previously found in East Asia, connecting the dots into lines and surfaces, and revealing a cultural transmission route from west to east and from south to north.”Gao also introduced the audience to pilo’s layered strata and fire ruins.The change of the stratum indicates that the climate change did not prevent the ancient human from climbing the plateau, and the human had a strong survival ability at that time.The use of fire, especially the controlled use of fire, is very important for the survival and evolution of human beings. It promoted the evolution of human beings. The application of heat treatment technology helped people really enter the door of civilization…”We have a kind of admiration for our ancestors’ courage and ability to climb the plateau.The vitality is impressive.””Ninety-nine percent of human history has not been written down,” Gao said. “To archaeologists, the layers of earth are like the pages of a history book, and the cultural relics and relics contained in the layers are the words of history, but they need to be decipherable.”It is understood that another round of excavations will begin at pilo site this year.What surprises will it bring?This dense history of strata, relics and remains will continue to be identified and interpreted by archaeologists in the near future.
