Throughout the 20th century, the fascination with the Yeti grew stronger. Two expeditions — one that almost included Edmund Hillary — were mounted in the 1950s in search of these creatures.
Debunking the theory, Charlotte Lindqvist, associate professor at the University of Buffalo College of Arts and Sciences, had said: "Our findings strongly suggest that the biological underpinnings of the Yeti legend can be found in local bears. Brown bears roaming the high altitudes of the Tibetan Plateau, and brown bears in the western Himalayan mountains, appear to belong to two separate populations. The split occurred about 650,000 years ago during a period of glaciation," reported AFP.
