Unlocking the Past: Meet the 1930s ‘Dragon Man’ and the Ancient Human Species He Reveals

A skull, known as the ‘dragon man,’ has stirred excitement in the anthropology world. Initially thought to be a unique species, new research shows it actually belongs to the Denisovans, our ancient relatives.

Paleontologist Qiaomei Fu led two studies using advanced techniques to analyze proteins and mitochondrial DNA found in the skull, which was discovered in the 1930s in Harbin, China. This region, under Japanese occupation at the time, is home to the Longjiang River, giving the skull its nickname.

The skull spent decades hidden in a well until it was donated to Hebei GEO University in 2018. In 2021, it was declared a new species, Homo longi, based on physical characteristics. However, Fu’s findings challenge this classification. She explains that physical traits can vary widely due to environmental factors, making them unreliable for categorizing species.

The breakthrough came when Fu’s team successfully extracted proteins and DNA from the skull’s dense petrous bone and dental plaque. Surprisingly, they found that the DNA from dental calculus was better preserved than from bone, suggesting this may be a valuable source for studying ancient human DNA.

While the skull’s physical features initially suggested it was unlike other hominins, the genetic analysis revealed it shares traits with at least five other Denisovans. The team identified specific proteins that tightly link the skull to this ancient group, which had previously been recognized only through fragmented remains.

This discovery highlights the limitations of our current understanding of human evolution and the importance of these ancient relatives. As of now, we might have lost a distinct species, but we’ve gained vital insights into the Denisovans, making this find critical for understanding our history.

Interestingly, the research further underlines a trend in scientific discoveries: many significant findings are often hidden in plain sight, waiting for the right techniques or perspectives to reveal their secrets.

The studies are published in Science and Cell, encouraging a reevaluation of what we think we know about human evolution.
