Yeti Could Exist, Respected Expert Says

In a BBC TV interview, Britain's Sir David Attenborough said he is "absolutely baffled" by footprints that may have been left by such a creature. This coould mean that yet, or abominable snowman, could exist.

"Very, very convincing footprints have been found," at 19,000-foot elevations, he said. "Nobody goes up to 19,000 feet just to make a joke."

When asked about the Loch Ness Monster, Attenborough answered with skepticism. He argued that there would have to be more than one, and that they would likely need to come up for air and expose themselves.

Attenborough, 82, is known for his coverage of animals and nature for the BBC.

A photograph shows an alleged footprint of a yeti taken in December 1951 near Mount Everest. British naturalist and broadcaster Sir David Attenborough said Friday he thinks it's possible that the legendary abominable snowman, or yeti, exists.
