For all of the grainy video footage, Bigfoot has never been revealed as anything more than a resilient hoax, and a new study only provides more evidence for the complete lack of evidence: after genetically testing 30 hair samples attributed to Bigfoot by museums and amateur hunters, a team of scientists was unable to match the samples to a new species, as USA Today reports. What was originally identified as a yeti may have been an undiscovered species of bear What was originally identified as a yeti — the Nepalese version of the Bigfoot — may have been an undiscovered species of bear, possibly some kind of mix between a brown bear and a polar bear. Those results are preliminary, though, and either way wont do much to assuage the Bigfoot aficionados who contributed samples to the study, which was published this week in Proceedings of the Royal Society B: Biological Sciences.
