Yes. Two studies published in 2025 support identifying the Harbin cranium nicknamed “Dragon Man” as Denisovan: one reported Denisovan mitochondrial DNA in dental calculus, and another identified proteins consistent with a Denisovan lineage. The DNA result is mitochondrial—not a nuclear genome—and the findings do not, by themselves, settle whether the proposed species name Homo longi should be retained.
Who was Dragon Man?
“Dragon Man” is a nickname for the nearly complete Harbin cranium, a human fossil reported found in Harbin, northeastern China, during bridge construction in 1933. The discovery account is reported history; the fossil does not have a precisely established excavation location.

In 2021, researchers proposed the species name Homo longi for the cranium, based on its anatomy and a phylogenetic analysis. They argued that it represented a distinct Middle Pleistocene lineage. A contemporary review described a combination of features: the face appeared more similar to Homo sapiens, while the elongated braincase shared similarities with H. heidelbergensis or Neanderthals. The 2021 review discusses the original classification.
How old is the Harbin skull?
The Harbin cranium is at least 146,000 years old, according to the dating reported in the fossil research and summarized by the Natural History Museum. That is a minimum age, not an exact date.
#1 Best Overall
In 2021, Junyi Ge of the Chinese Academy of Sciences said the available evidence placed the cranium in water-laid sediments in the Harbin region dated between 138,000 and 309,000 years ago, while noting that its exact location could not be pinned down with the technology then available. That contemporaneous provenance estimate is not a replacement for the later studies’ minimum-age figure.
What did the DNA study find?
A 2025 study reported Denisovan mitochondrial DNA recovered from dental calculus associated with the Harbin cranium. The Cell paper provides a direct molecular link between a Denisovan genetic signal and this nearly complete fossil.
Rank #2
Mitochondrial DNA is inherited through the maternal line and represents only one genetic lineage. It is not the same as recovering a nuclear genome, which contains genetic material inherited from both parents. The result supports Denisovan affiliation, but it should not be described as a full-genome identification.
What did the protein study add?
A separate 2025 study reported 95 endogenous proteins from the Harbin cranium and concluded that the individual belonged to a Denisovan lineage. This provides a second, complementary molecular line of evidence rather than another DNA result. The Science study abstract reports the protein analysis.
How do the findings change the original classification?
The evidence addresses different questions, so the change is not simply a case of DNA replacing the original name.
| Evidence | What it indicates | What it does not establish by itself |
|---|---|---|
| Cranial morphology and phylogenetic analysis (2021) | The Harbin cranium’s anatomical relationships; the team proposed Homo longi. | A direct molecular identification of the individual as Denisovan. |
| Mitochondrial DNA in dental calculus (2025) | A Denisovan maternal-line genetic signal associated with the cranium. | A nuclear genome or a definitive resolution of species rank. |
| Proteins from the cranium (2025) | A separate molecular result supporting Denisovan lineage affiliation. | Whether Homo longi is a valid separate species name, a synonym, or should be treated another way. |
The molecular evidence supports identifying the individual as Denisovan. Whether Denisovans should be named Homo longi, whether that name is synonymous with another classification, or how the fossil should be formally classified remains a taxonomic question not resolved by the cited findings. A biological affiliation and the formal naming of a species are related, but they are not interchangeable conclusions. A 2025 Chinese Academy of Sciences account describes the new molecular evidence and its implications.
Rank #4
Did scientists recover DNA from the Dragon Man skull?
They reported mitochondrial DNA from dental calculus associated with the Harbin cranium—not a nuclear genome recovered from the skull itself. A distinct study analyzed proteins from the cranium. Together, the results support Denisovan identity while leaving the formal status of Homo longi open.
