Denisovan remains identified in southwest China's Bianfu Cave
Quick Look
- Two papers published in Nature on September 9 identify Denisovan remains in Bianfu Cave, southwest China, establishing it as the richest Denisovan site outside Siberia.
- The research, involving the Chinese Academy of Sciences and Yunnan Provincial Institute, uses ancient protein analysis to confirm the findings.

Why It Matters
Denisovans are an extinct hominin group that diverged from modern humans and Neanderthals hundreds of thousands of years ago. Since their discovery in 2010, few remains have been found, limiting scientific understanding.
Within the region’s coniferous forests and forest-steppe environments, this archaic human group established a stable subsistence pattern highly adapted to local resources through specialised hunting and the intensive exploitation of animals.
The extinct Denisovans once roamed Eurasia, having diverged from modern humans ( Homo sapiens) and Neanderthals several hundred thousand years ago.
Since Denisovans were first identified in 2010, research has yielded only a handful of molecularly identified remains, leaving scientists with a limited understanding of the species.
On September 9, two papers co-authored by researchers from institutions including the Chinese Academy of Sciences (CAS) and the Yunnan Provincial Institute of Cultural Relics and Archaeology were published simultaneously in Nature. The two papers overlap in their study focus and some of the researchers are cited as authors on both papers.
One paper, titled “Ancient proteins identify various Denisovan remains from southwest China”, said the findings “establish Bianfu Cave as a Denisovan locality yielding the most abundant remains of this hominin group outside Denisova Cave in Siberia”.
Open Questions
- What was the exact timeline of Denisovan occupation in Bianfu Cave?
- How do the southwest China Denisovans relate genetically to those from Siberia?
- What tools or cultural artifacts accompanied the remains?
- Why did Denisovans go extinct while Homo sapiens survived?
