  Scientists make shocking discovery Yeti

Scientists have examined DNA samples that were supposed to be from Yetis, and discovered that, in fact, they are only bears.

A study published this week in the Proceedings of the Royal Society B tries to get to the question of whether the mythical Yeti Himalaya exists. They examined nine different specimens of supposed Yetis and came to some very interesting conclusions, namely that the DNA came from Tibetan brown bears, brown bears from the Himalayas and an Asian black bear.

In addition, the ninth specimen came from a dog, which means that even the best potential clues to the existence of a Yeti turn out to be fairly common animals. The findings are in direct contradiction to a 2014 study conducted by Bryan Sykes, an Oxord geneticist, who said there was a genetic match between Yeti samples and an ancient polar bear tens of thousands of years ago.

Sykes thought that this Yeti might be an unknown species of bear that may have descended from this polar bear, but this study also flies that less ambiguous theory and reveals that, in fact, they are only samples of animals that we already know in I live in the area. 19659004] The complete statement from the University of Buffalo follows below.

The Yeti or Abominable Snowman, a mysterious monkey-like creature that inhabits the high mountains of Asia, occupies a prominent place in the mythology of Nepal and Tibet. [19659004] Sightings have been reported for centuries. Footprints have been seen. The stories have been pbaded down from generation to generation.

Now, a new DNA study of alleged Yeti samples from museums and private collections is providing insight into the origins of this Himalayan legend.

The research, to be published in Proceedings of the Royal Society B, badyzed nine "Yeti" specimens, including samples of bones, teeth, skin, hair and feces collected in the Himalayas and the Tibetan plateau. Of those, one turned out to be from a dog. The other eight were from Asian bears: one from an Asian black bear, one from a brown bear from the Himalayas and the other six from brown Tibetan bears.

"Our findings suggest that the biological foundations of the Yeti legend can be found in local bears, and our study shows that genetics should be able to unravel similar mysteries," says lead scientist Charlotte Lindqvist, PhD, professor Associate of Life Sciences at the University of Buffalo School of Arts and Sciences, and visiting badociate professor at Nanyang Technological University, Singapore (NTU Singapore).

Lindqvist's team is not the first to investigate "Yeti" DNA, but previous projects performed simpler genetic badyzes, leaving important issues unresolved, he says.

The study represents the most rigorous badysis to date of samples suspected of being derived from anomalous or mythical creatures & # 39; hominids & # 39 ;, "Lindqvist and his coauthors write in their new paper.

The science behind folklore

Lindqvist says that science can be a useful tool to explore the roots of myths about great and mysterious creatures.

She points out that in Africa, the legendary Western legend of a " African unicorn "was explained at the beginning of the 20th century by British researchers, who found and described the flesh and bone okapi, a giraffe relative that resembles a mixture between that animal and a zebra and a horse.

And in Australia, where large people and animals may have coexisted thousands of years ago, some scholars have speculated on references to huge animal-like creatures in Australia's "Dreamtime" aboriginal mythology. It may have come from ancient encounters with the royal megafauna or its remains, known today as the fossil record of Australia.

But while such connections remain uncertain, Lindqvist's work, like the discovery of the okapi, is straightforward: "Clearly, a large part of the Yeti legend has to do with bears," he says.

She and her colleagues investigated samples such as a piece of skin on the hand or leg of a "Yeti" – part of a monastic relic – and a femur fragment of a decayed "Yeti" found in a cave on the plateau Tibetan The skin sample turned out to be of an Asian black bear and the bone of a Tibetan brown bear.

The "Yeti" samples that Lindqvist examined were provided to him by the British production company Icon Films, which presented it at the 2016 Animal Planet special "YETI OR NOT", which explored the origins of the legendary being.

Solving a scientific mystery, too: How enigmatic bears evolved

In addition to tracing the origins of the Yeti legend, Lindqvist's work is discovering information about the evolutionary history of Asian bears.

"Bears in this region are vulnerable or critically threatened from a conservation perspective, but not much is known about their past history," he says. "The brown bears of the Himalayas, for example, are in grave danger of extinction, and clarifying the population structure and genetic diversity can help estimate the size of populations and develop management strategies."

Scientists sequenced the mitochondrial DNA of 23 Asian bears (including the supposed Yetis) and compared these genetic data with those of other bears worldwide.

This badysis showed that, although Tibetan brown bears share a common ancestor with their North American and Eurasian relatives, the brown bears of the Himalayas belong to a different evolutionary lineage that diverged at the beginning from all other brown bears.

The division occurred approximately 650,000 years ago, during a period of glaciation, according to scientists. The timing suggests that the expansion of the glaciers and the mountainous geography of the region may have separated the Himalayan bears from others, leading to a prolonged period of isolation and an independent evolutionary path.

"More genetic research on these rare and elusive animals will help illuminate the environmental history of the region, as well as have a global evolutionary history, and additional samples of 'Yeti' may contribute to this work" , says Lindqvist.
