An ancient jawbone, discovered in the Penghu Channel off Taiwan, has been confirmed as belonging to a Denisovan male, marking a major addition to the fossil record of this mysterious group of ancient humans. The specimen, likely over 10,000 years old, provides insights into Denisovan adaptation to diverse environments from Siberia to Southeast Asia. Confirmed through protein analysis, it showcases the species' prominent jaw and large molars, underscoring their coexistence and interbreeding with modern humans and Neanderthals. This discovery, alongside previous findings, suggests Denisovans had a wide geographic range and diverse habitats.
