Recent findings of ancient jawbone fossils from Taiwan and surrounding regions have provided significant insights into the Denisovans, a mysterious group of archaic human ancestors. Researchers confirm that these fossils expand the geographic range of Denisovans, revealing their presence in areas from Siberia to Southeast Asia and even Taiwan. Notably, a jawbone dredged from the seafloor highlights the connection of Denisovans to the Pacific Coast, while another fossil discovered off the coast of Thailand suggests a broader habitat than previously understood. These discoveries build a richer image of the Denisovans, showcasing their robust nature compared to Neanderthals and hinting at their adaptation in diverse environments.
