For thousands of years, native Himalayans and visitors have been convinced that the Himalayas are home to a mysterious, bipedal, apelike creature called the Yeti. (Just like Pacific Northwesterners have believed in Sasquatch.) Stories of the Yeti date all the way back to the Lepcha culture in modern-day Bhutan and Nepal, and they've persisted into modern times. But like most cryptids, there has never been concrete evidence of the Yeti's existence, like a living specimen or even a carcass. The best Yeti enthusiasts have been able to offer is shaky proof like footprints or samples of doubtful origin.

In 2016, a documentary film crew gathered some of these "Yeti" samples and asked a team of biologists at the University at Buffalo to examine them. The team examined a collection of hair, bone, skin, and excrement supposedly belonging to a Yeti. DNA analysis revealed the samples mostly came from either Himalayan brown bears or black bears.

Like the Loch Ness Monster, it's most likely that people have been mistaking a relatively common animal sighting for something fantastical. The fact that so many cultures around the world have reported seeing cryptids like the Yeti means one thing: Brief encounters with apex predators can confuse pretty much anyone.
