Is This Monster Real?

Back in 1951, two men were climbing the Himalayan mountains in Central Asia when they spotted something strange: large, oddly shaped footprints in the snow. The prints were enormous33 centimeters (13 inches) longand they had an oversized thumb-like toe.  

The climbers suspected that the prints came from a legendary beast known as the yeti. For centuries, people had reported seeing the monster. Some had even collected bits of hair, bones, and droppings that they thought came from yetis

Despite this evidence, many people today doubt the monster exists. Biologist Charlotte Lindqvist (LIND-kvist) recently set out to investigate. She agreed to study several samples believed to belong to yetis as part of a documentary about the monster. Her questions: Did the samples come from a known animal? Or did they belong to  something more mysterious?

Who's Who?

Fantastical creatures are often inspired by real animals. For example, European explorers of the Americas mistook manatees for mermaids. Lindqvist thought theyetisamples might belong to bears. But she knew that they could also come from an unknown species.

To find out, Lindqvist studied the in the hairs, bones, and droppings that supposedly came from yetis. DNA is found inside , the microscopic units that make up an animal’s body. It contains information about the animal it came from.

First, Lindqvist and her team used chemicals to extract the DNA. They placed the DNA in a machine to analyze its structure. Then they used computers to compare the DNA with that of other animals.

Beyond Yetis

Did the samples come from a monster? Not exactly. Lindqvist found that the samples’ DNA matched the DNA of several bears from the region, including the Himalayan brown bear. One sample, a tooth, belonged to a dog

The analysis also revealed something new about the of bears. Evolution is the process by which organisms change over many generations. These changes build up over time in a species’ DNA.

Lindqvist found that the Himalayan brown bear has been isolated from other bear species for 650,000 years. The Himalayan brown bear is in danger of going extinct, or dying out. Learning more about its history could help scientists save the species.

As for yetis, Lindqvist doesn’t think her findings will stop people from believing in the monster. Tales about yetis are an important part of the local culture. “Science isn’t going to change that, and maybe it shouldn’t,” she says. “These mysteries are going to survive.”
