Chinese scholars in Guangxi have found that rice belongs to silicon implants 16,000 years ago

BEIJING, Aug. 1 (Xinhua Sun Self-Law) Chinese researchers have made the latest important achievements in the use of ancient human plants through cooperation and research at the site of Yahuaidong in Guangxi, southern China, about 30,000 years ago, in which 16,000 years ago, rice was found to be a silicon implant, providing important evidence for the ancient human use of wild rice.
Reporters on August 1 from China
Institute of Paleontology and Paleoanthropology (
Institute of Paleontology) was informed that the Institute's Wu Wei associate researcher and Guangxi Institute of Cultural Heritage Protection and Archaeology Xie Guangmao researcher, China Society
Institute of Archaeology Zhao Zhijun researcher, etc. , on the Yahuaidong site series of samples of the site of ancient plants remains research, the results of the paper recently published in China Science - Earth Science online.
team used radiocarbon isotopes to measure the year, combining the remains and relics of ancient human sites in Yahuaidong to establish the age frame of the research site. Through silicon implant analysis, supplemented by spore powder information, access to ancient human plant resources information. The study found that ancient humans used different plant species over different time spans: in the deep-sea oxygen isotope Phase 3 to Heinrich Phase 1, the genus Python was found, and bamboo and palms appeared throughout the time series. More importantly, the researchers found that the rice genus was planted with silicon 16,000 years earlier, providing important evidence for the ancient humans' use of wild rice.
At the same time, the cooperative study also found that the unique combination of stone tools at the Yahuaidong site is similar to that of northern china rather than southern China, suggesting the possibility that the migration of ancient humans south of the colder north brings the tools and techniques they are used to. This shows that the warm Guangxi region not only provides an important way for the spread and migration of ancient humans, but also is an ideal shelter to avoid sudden climate events.
industry experts point out that the last 30,000 years are a critical period of late-life global climate change, with widespread and profound effects on humanity. Guangxi is one of the famous fossil origins of ancient human beings, and it is also a key region for the emergence and evolution of modern human beings. Previously, however, there had been relatively little research on the types and methods of plant use in this area.
It is understood that, as one of the important discoveries of ancient stone archaeology in Guangxi in recent years, yahuaidong site is located in Longan County, Guangxi, including the cultural relics of different periods of the old and Neolithic periods, Guangxi Institute of Cultural Relics Protection and Archaeology through excavation, has found in Yahuaidong site China's rare complete human skull fossils, as well as a large number of stone-making and mammalian fossils.
