Denisovan fossil shows the enigmatic human cousins living in Siberia to the subtropical
The third location of hominan that known as Desiosovans is shown by these human cousins adapted to a visible range of environments

A fossilized jawbone found almost two decades on the Taiwano coast It was a male denseovanScientists have found that this enigmatic group of archaic human beings confirm that he has crossed a wide geographical range, from Siberian snowmills to subtropical forests. Unlike their Neanderthal cousinsHowever, Densovans left a few physical traces behind: It is a third location than the remains of verification since it was found 15 years ago.
A Shortage of fossils It is striking because Evidence of DNA suggests that Uksovans Asia flourished hundreds of thousands of years over the East. However scientists had There is no existence until 2010When researchers realized that A finger bone“Too later, other bone parts of the Siberian Denisova cave, was completely unknown in hominin tree. Another decade passed before Mandible with two molarsA Buddhist monk in a 1980 Tibetan cave found Related to the same fleet lineage.
“To continue very little,” says Frido Welker, a molecular Anthropologist at the University of Copenhagen and the author of the author of the new Jawbone analysis was published on Thursday Science. Fossils in Sibesh and Tibetan revealed that the Eurasian continents began to walk 200,000 years ago and survived for a long time Anatomically modern human beings interbreed As the latter comes out of Africa About 50,000 years ago. But the disk is sufficiently scarce, Welker says, “The informative is all the pieces that change our photo.”

Its team finds shows that Denseovans could not only be suffered from a severe Siberian winter and a highly highly tibetan plain. “It shows that they were very adaptable,” Bena, the viola, paleoanropologist, at the University of Toronto, who did not participate in this research. Besides Homo sapiensThere is no other Hominin group, not too strong neautermal, dominated many different environments.

Jawbone (formally known Penghu 1) Penghu was taken down from the channel, from the west coast of Taiwan, as a commercial fishing dredge before 2008 and described in a study Nature In 2015. His DNA degraded to identify. So Welker and his colleagues are protein, which take more time with complex biomolecules. Fossils found two variants that are very popular “to identify confidence”, Janet Kelso, Liipzig, Germany, German Biologist at the Max Planck Institute in Planck.
For many researchers who work in this field, this confirmation is not surprising. “Everything we all expected would be in Denisovan,” says Violak, his strong structure that was similar to the Mandibulo of Tibetan. He was also not the first advice of the presence of Denisovan in a wider region: A group of researchers in 2022, including Welker, reported A molar that resembles the specimens of Tibetan Found in a caveman in Mount Laos mountains. But like Penghu 1, his DNA was very far away, so it is not a burning test. It is possible, however, that the molar can eventually be tested using Welker’s protein analysis technique.
Jawbone also adds context that Viola calls a “mystery”. The comparisons of Denisovan DNA shows that many of the ancient homininen genes now live in people, from Australian aborigines to native Americans. Today’s inhabitants have found the highest rate of DNOISOVAN DNA Philippines And the island New Guineawell Other Pacific IslandsBut “It was hard to be square with the places we have at Densovan fossils,” says Violak. Siberia and Oceania are not exactly neighbors.
This new study provides another anchor point in Densovans and early modern humans that genes could be known and changed, Emilia Huerta-Sánchez, the genetic population, from Brown University, who did not participate in the study. His work has shown that Different genetically distinctive population of Densovan He works in interthominin unions and a DN of those who got from them offered them an evolutionary advantage (eg accordingly) Tibetan allows you to breathe their thin air air).
Penghu 1’s proteins are not, however, many do researchers understand the flow of gene, depending on Huerta-Sánchez, according to Huerta-Sánchez. “It’s a bit of data,” it indicated that they are soaked in these ancient interactions, “it would be nice to take a whole genome from a geographical location,” somewhere outside of Siberia and Tibetet. That is, in itself difficult difficulty, seeing the fragility of DNA, especially in warmer climates.
Welker said until more data wants to speculate how our cryptic relatives are included in the story of humans. For now, Jawbone marks the new brand of “Our Hominin family”, “and places another bread in the Trade of Densovan.
