China Cave Unlocks 167,000-Year-Old Hominin Life

Archaeologists in southwestern China have discovered new fossilized remains belonging to Denisovans, an enigmatic group of extinct hominins. Excavations at Bianfu Cave in Yunnan province have yielded seven Denisovan fossils, alongside bone and stone tools, and animal remains. These finds suggest how Denisovans lived in the region's conifer forests between 167,000 and 134,000 years ago.

This discovery is particularly significant as it represents the first site in southern China to directly associate Denisovan fossils with abundant cultural artifacts. Previously, Denisovan evidence was often sparse and of uncertain origin, making this find invaluable for understanding their behavior and habits.

The Bianfu Cave fossils, including teeth and part of an arm bone, add to the limited known Denisovan remains. Researchers were able to analyze ancient proteins from some teeth, confirming their Denisovan origin. The site's relatively undisturbed context allows for more reliable dating and offers a clearer picture of Denisovan occupation.

This discovery also expands the known geographical range of Denisovans, indicating they occupied diverse environments from Siberian mountains to subtropical latitudes. The findings challenge earlier assumptions and provide a unique glimpse into the lives of these ancient human relatives.
