Ancient Denisovan jawbone rewrites human migration in subtropical Asia

A remarkable fossil discovery has pushed the known range of Denisovans deep into southeastern Asia. The Penghu 1 mandible, pulled from the seabed near Taiwan, confirms these ancient humans lived far beyond their previously documented habitats. Scientists now have direct proof of their presence in warm, humid subtropical regions.

The fossilised jawbone was found in the Penghu Channel, off Taiwan’s coast. Dating suggests it is from the Pleistocene epoch, somewhere between 10,000 and 70,000 years old—though it could be as old as 130,000 to 190,000 years. Its robust structure, with powerful jaws and oversized molars, sets it apart from both Neanderthals and modern humans.

Paleoproteomic analysis sealed its identity as Denisovan. This marks the first time molecular evidence has placed these hominins in southeastern Asia. Previously, Denisovans were known mainly from cold, mountainous sites like Siberia’s Denisova Cave. The find reshapes understanding of their adaptability. Unlike their Siberian relatives, these Denisovans thrived in Taiwan’s warm, humid climate. Their ability to occupy such varied environments suggests a species far more flexible than once assumed. Denisovans also left a genetic legacy. They interbred with Neanderthals and early Homo sapiens, passing on DNA still found in modern East Asian populations. Researchers now plan deeper studies into their migration routes, survival strategies, and interactions with other ancient humans.

The Penghu 1 mandible extends the Denisovan story into new territory. It provides concrete evidence of their life in southeastern Asia and hints at a wider, more complex history. Future work will focus on unravelling how these adaptable hominins moved, lived, and influenced human evolution.
