An international team of researchers has unearthed evidence shedding new light on the ancient migration of Homo sapiens into eastern Asia around 45,000 years ago.
The findings, detailed in a study published in Nature Ecology & Evolution, uncover what is said to be a treasure trove of cultural and technological innovations in the Shiyu site in northern China, marking what is considered a significant moment in human history (https://www.nature.com/articles/s41559-023-02294-4).
According to the researchers, the Shiyu site provides a glimpse into the unique convergence of cultural behaviors and technological advancements of our ancient ancestors, and challenges conventional beliefs about the dispersal of Homo sapiens populations.
Key revelations from the research include:
Shiyu now stands as the oldest and easternmost site of its kind, showcasing Homo sapiens’ presence in eastern Asia around 45,000 years ago as demonstrated by radiocarbon and luminescence dating led by Professor Jia-Fu Zhang of Peking University. This discovery reshapes our understanding of the timing and routes of human migration in the region.
Shiyu exhibits what is described as a remarkable array of technological advancements, including stone tools crafted using Levallois and Volumetric Blade Reduction methods. Additionally, the long-distance transport of obsidian from sources hundreds of kilometers away indicates advanced resource procurement strategies.
Shiyu showcases a cultural blend characterized by a mix of Upper Palaeolithic innovations such as blade reduction and symbolic tools, Middle Palaeolithic traits such as Levallois reduction, and traditional elements of Chinese core-flake industries. The discovery of unique artifacts, such as a shaped graphite disc and bone tools, illustrates, it is claimed, a rich cultural adaptation.
The discovery, say the study authors, presented a different view of human migration and cultural evolution than previous studies of the Shiyu location.
“The Shiyu findings challenge previous notions of early human migration and cultural development in Eastern Asia,” said study author Michael Petraglia.
