Chinese researchers have made the latest important achievements in the use of ancient human plants through collaborative research at the site of Yahuaidong in southern China, about 30,000 years ago, in which the discovery of 16,000-year-old rice-genus silicon has provided important evidence for the use of wild rice by ancient humans.

Reporter August 1 from the Chinese Academy of Sciences Institute of Paleovertebrates and Paleoanthropology (Chinese Academy of Ancient Spine Institute) was informed that the Institute Wu Wei Associate Researcher and Guangxi Institute of Cultural Relics Protection and Archaeology Xie Guangmao Researcher, the Institute of Archaeology of the Chinese Academy of Social Sciences Zhao Zhijun researcher, etc. , the Yahuaidong site series of samples for the site of the ancient plant remains research, the results of the paper recently published in the “China Science – Earth Science” online.
The cooperative research team used radiocarbon isotopes to measure dination and combine the remains and relics of the ancient human ruins of Yawaidong to establish the age framework of the research site. Through silicon analysis, supplemented by spore powder information, to obtain ancient human plant resources information. The study found that, in different time spans, ancient humans used different plant species: in the deep-sea oxygen isotope phase 3 to Heinrich 1, the genus plants were found; More importantly, the researchers discovered 16,000-year-old rice-seeded silicon, which provided important evidence of the use of wild rice by ancient humans.
At the same time, the collaborative study found that the unique stone combination at the Yawaidong site was similar to that of North China rather than South China, suggesting the possibility that the ancient humans moving south as the climate cooled to the north, bringing their usual tools and techniques. 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 refuge for avoiding sudden climate events.
Industry experts point out that the last 30,000 years are a critical period of global climate change in the late Pleistocene, with wide-ranging and profound human impacts. Guangxi is one of the famous fossil seishesofs of ancient humans, and it is also a key region for the emergence and evolution of modern human beings. However, there have been relatively few studies on the types and methods of plant utilization 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 Long’an 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 ya Huaidong site china’s extremely rare complete human skull fossils, as well as a large number of stone tools and mammal fossils.
