A skull, discovered nearly a century ago, has led to the new disclosure in the study of human development.
Known as “Dragon Man”, excavations are now recognized as belonging to Denisovans – a mysterious group of old humans that were first revealed by analyzing DNA in 2010.
“I really feel that we have cleared some ambiguity surrounding this population,” Cenomi Fu, a researcher who was part of the 2010 discovery team and led the new study, told CNN.
“After 15 years, we know the first Denisovan skull.”
The results also provide a glimpse of what Denisovan might seem. Scientists have rebuilt the impression of an artist about “Dragon Man”, which shows a strong and enjoyable face with the strong hills of the eyebrow, which is a common feature in other ancient human species.
With the size of the brain similar to both primitive human beings and modern human beings, Dinisovan could have a strongly strong appearance, they are likely to be adapted to the harsh environments it inhabits.
The “Dragon Man” skull, which dates back 146,000 years and discovered it in 1933 by a worker in Harbin, China – when it was under Japanese occupation – was shrouded in mystery.
The worker found the skull while building a bridge, but instead of handing him over to the science, he tiled it to the bottom of the well, where he had not touched it for decades until his death in 2018. Then his family donated to Hebei Geo University.
With almost the discovery of this full skull, scientists have finally collected the face of Denissovan, where they presented new visions in the history of humanity.
In 2021, scientists first suggested that the skull may belong to a new type of human being, or call it Homo Longi, or “Dragon Man”, derived from Heilongjiang, or Black Dragon River, which was found.
The unusual skull features – such as its huge hills and the low -faced face – were unlike those in any human species previously known. However, although this discovery was, it raised many questions.
The mystery deepened when the researchers fought to extract the DNA from the skull, which was buried for a long time. Despite many attempts, the initial efforts to analyze its genetic materials have proven unsuccessful.
It was not until scientists turned into a different source – the dental plate – they found the penetration they needed.
The DNA referred to a sudden link to dinisovan, an ancient human group that was identified through a small pink bone found in the Cave of Siberia a decade ago. The discovery of these fossils is the first evidence of Denisovan outside their original home in Siberia.
To date, the entire Denisovan skull has not been found, leaving only researchers with small pieces of puzzle to work with. The “Dragon Man” skull changes, providing an idea that affects the need to help scientists collect what these ancient relatives may seem.
New search, published in two pioneering papers in cell and sciencesNot only was the DNA of the mitochondria, but also revealed the fragments of the protein extracted from the skull that strengthened its identity. Denisovan.
The analysis of these proteins showed a clear match for the well -known Denisovan features, confirming the connection undoubtedly.
The discovery of “Dragon Man” adds a new layer to our understanding of human development, as it shed light on a period in which multiple human species on Earth wandered.
Denisovanz, primitive human beings, and the two sane and even overlapping, are living behind the effects of DNA in modern humans. In fact, many people today carry small quantities of DNA DNA, a legacy of these old meetings.
