"Bigfoot" Hair Samples are from Known Animals
For the first time, a thorough analysis of the mitochondrial DNA from hair samples alleged to be from a Bigfoot, Yeti, or related cryptid were carefully analysed and the results published in a peer-reviewed journal. The result – all of the samples were a 100% match to a known animals. Most were extant, two samples were from a fossil polar bear, and two could not obtain sufficient DNA to make a match.
Researcher Bryan Sykes and his team carefully removed any contaminants from the 57 samples that were sent to them, some recent, some from museum specimens decades only. They report that human contamination in past DNA examinations likely resulted in the anomalous results, that looked like human DNA mixed with other mammals. Such results were proclaimed by Bigfoot believers to be evidence of anomalous primates.
Sykes, however, demonstrated that simply thoroughly removing contaminants also removes the anomalous DNA. What was left was the mitochondrial DNA from bears, sheep, wolves, raccoon, deer, and similar common mammals.
These results contradict the claims by Ketchum and others from 2012 in which they found human mitochondrial DNA with non-human nuclear DNA in alleged bigfoot samples. At the time the results were criticized as likely the result of contamination, and that conclusion now gains further support from Sykes and his team.
Ketchum further claimed she couldn’t get her paper published in a reputable journal because the editors did not want to touch a controversial topic like Bigfoot, but Sykes proves that claim wrong also. Further, independent analysis found Ketchum’s samples to be a mix of opossum and other mammals.
Bottom line – still no convincing evidence for Bigfoot.
