Yeti

Over the years, there have been various theories put up about the Yeti, a giant humanoid, ape-like monster thought to live in the upper Himalayas. Even though anecdotal accounts and local legend have mentioned this creature for much longer—the Lepcha people even revere it as a deity of the forest beasts—it wasn't until 1951 that it gained international attention due to a photograph of what many believed to be the creature's footprint.

Since then, mountaineers from all over the world have shared their own encounters with the Yeti, along with what they believe to be pieces of the creature's skin, hair, teeth, or other artifacts.

Although no such monster has ever been found in the area, the mystery has persisted. In reality, a team of scientists discovered evidence of bears as a potential explanation for all the Yeti sightings when they put some of those samples through a DNA test. Bears are far more dangerous and elusive than Yetis. Except for one, which came from a domestic dog, all of them were samples taken from Himalayan black or brown bear species.
