The Yeti. Also known as the abominable snowman. It's a legendary primate some people believe exists in the Himalayas and adjacent frozen lands. But what do you get when you use modern DNA techniques to analyze bodily samples allegedly left by yetis? Well, eight times out of nine, you wind up with the genetic signature of your non-abominable neighborhood bear.
These unmysterious results are revealed in the Proceedings of the Royal Society B.
This new study is not the first to examine DNA extracted from samples allegedly derived from yetis. Analysis of short DNA fragments from a pair of samples collected in India and Bhutan matched that of an ancient polar bear bone. That 2014 finding raised the possibility that the abominable snowman could actually be a previously unrecognized bear species—or even some sort of hybrid brown bear-polar bear that wanders the Tibetan plateau.

In the current study, researchers conducted a more comprehensive comparison of DNA from 24 samples, including nine that supposedly came from yetis. These specimens, collected from the field or borrowed from museums, included bits of hair, bone, skin and scat.
Eight of the nine yeti samples were identified as actually coming from the Asian black bears, Himalayan brown bears and Tibetan brown bears that call this remote region home. But what about that ninth sample? Yeah, it was from a dog. The abominable Fido, maybe.
On the serious side, the analysis did address a mystery of a more scientific nature regarding the evolution of these local bear populations. The results suggest that Himalayan brown bears belong to a distinct evolutionary lineage that diverged from the other bears during the greatest of earth's ice ages.
Cut off by the spread of glaciers, these bears have been keeping to themselves for more than 660,000 years. That period of isolation has rendered them rare and elusive—but still very real. Which we cannot say about the abominable snowman. At least not yeti.

在目前的研究中，研究人员对来自24个样本的DNA进行了更全面的对比，其中9个样本据推测来自雪人kaYZEugrS7。这些样本有的是从野外收集来的，有的是从博物馆借来的，包括毛发、骨骼、皮肤和粪便RR|p4zGWG-[jb)K[eg。
