Mysterious human skull Researchers say that the discovery in the 1930s, discovered in the 1930s, have been identified as an existing species after once thought to be a new species together.
Research submitted to Journal Cell and Science has identified the 146,000-year-old skull known as “Dragon Man” as classified as Denisovan.
Researchers revealed that Denisovan was discovered by them Genomes and proteins To identify them.
However, the reason it took so long to identify is that the attempt to extract DNA from the teeth failed.

Researchers also tried to extract DNA from the skull of Harbin’s head, but this failed.
When these methods failed, researchers ended up using dental calculations using calcification Dental plaque.
Calcified dental plaques can retain and protect DNA due to their dense crystal structure that resists degradation in a variety of environments.

At the location sampled for 0.3 mg dental calculus of Harbin teeth, mtDNA was captured and sequenced (pictures provided by Qiaomei Fu via journal cells)
Researchers used bleach on dental plaques to eliminate modern DNA.
Once extracted, researchers began comparing the discovered genetic material with previous samples.
Researchers have discovered that “Dragon Man” is not a new species, but a Denisovan, the first intact specimen to date.
Researchers say Denisovans coexist with modern humans and are closely associated with Neanderthals.

The skull was donated in 2018 just before his death, and his family later moved the skull and handed it to Geo-Kei Geo at the Geo Science Museum University Professor Qiang ji.
The research has limitations, but the researchers said there is still much to learn to move forward.
It was known as the “Dragon Man” because it was discovered in Jiangxi Province, China, which translated into the Black Dragon River.
