The case record
What was reported?
Yeti traditions and expedition accounts describe an elusive Himalayan being, often reconstructed in Western media as a giant snow-dwelling ape. Local names and narratives vary, and the modern biological claim should be separated from religious and cultural meanings.
Mountaineers publicised unusual snow tracks, while hair, bones and other objects were later offered as yeti remains. Such objects have a testable identity even when the circumstances in which they were collected are uncertain.
1921 is a conventional starting point for English-language mountaineering publicity, not an origin date for Himalayan traditions. The filter range includes later sample investigations, not a continuous sighting.

Evidence in the record
A 2017 genetic study examined nine purported yeti samples: eight came from Asian bears and one from a dog. The University at Buffalo report explains both these identifications and the study’s additional work on regional bear ancestry. It did not test every reported sighting or footprint.
Competing explanations
Official and research context
The reviewed study identified the nine submitted purported yeti samples as eight bears and one dog; it did not test every report.
Conventional explanations
Bears account for the tested material; overlapping prints and snowmelt can alter apparent footprint size and shape. These explanations reduce the need for an unknown ape without treating diverse Himalayan traditions as failed zoological descriptions.
Arguments that remain contested
Reviewed the university’s case-specific study release and a historical overview. Genetic conclusions apply to the submitted samples; broad claims that all yeti traditions have been disproved would exceed the evidence.
