A scientific row about Bigfoot has escalated in America after a researcher published 'DNA proof' of its existence - in a journal they earlier purchased and renamed

Texan Melba Ketchum claims she has spent five years studying DNA samples of the Bigfoot.

Ketchum insists she can prove samples of its hair, blood, saliva and urine are genuine. She adds that following work of a team under her direction at DNA Diagnostics, also in Texas, she knows the mythical animal is a real human-primate hybrid.

She has asked the US government to recognise Bigfoot's kin as an indigenous people who require official protection.

Her group have published the following 19-second clip of a 'sleeping bigfood' recorded in Kentucky in 2005. It has not explained the context of the clip or why it took eight years for the 19 seconds of footage to emerge.


Ketchum also claims that her attempts to have her work peer-reviewed and published in well-known journals were blocked by scientists embarrassed to admit the yeti may exist.

"We encountered the worst scientific bias in the peer review process in recent history," Ketchum wrote recently.

"Several journals wouldn’t even read our manuscript when we sent them a pre-submission inquiry."

Eventually a paper containing her claims and evidence was published in the 'DeNovo Scientific Journal'. But while the journal claims it is peer-reviewed, this has been questioned by other scientists who say the journal is a stooge for Ketchum's data.

Ketchum has now admitted buying the rights to the journal and renaming it, but says her research was peer-reviewed and accepted before she did so:

"After this journal agreed to publish the manuscript, their legal counsel advised them not to publish a manuscript on such a controversial subject as it would destroy the editors’ reputations (as it has already done to mine).

I have documentation on all of this drama.

So, rather than spend another five years just trying to find a journal to publish and hoping that decent, open minded reviewers would be chosen, we acquired the rights to this journal and renamed it."

Academic and anthropologist Jeff Meldrum told HuffPost in the US that he wouldn't rule out that some publications were biased against running papers in favour of Bigfoot's existence - but said Ketchum's behaviour didn't inspire confidence in her claims.

Meanwhile other researchers continue to claim proof of the sasquatch's existence, though none has yet delivered conclusive video or photographic evidence.

    As a motor biker was driving through the Grand River area of Ohio in April 2012, an alleged Bigfoot ran across the road and was caught on videotape.

  • Depicted is an illustration of a creature reported to inhabit the Kemerovo region of Siberia. Scientists from the U.S., Russia and other countries have yet to find one of these creatures known as the Russian Snowman. In early October, researchers claimed to be 95 percent certain that the animal exists.

  • An alleged footprint of a Yeti, or Abominable Snowman, appears in snow near Mount Everest in 1951. Now, scientists are setting out to find evidence of a reported unknown, hairy, bipedal creature known as the Siberian Snowman.

  • Bigfoot or bear? Impression left on the driver's side window of a pickup truck owned by Jeffrey Gonzalez. The bizarre image was left by an alleged Bigfoot in California's Sierra National Forest over Memorial Day 2011. DNA samples of the impressions will eventually determine the identity of the animal responsible for them. (See next slide for a close-up of the paw-like impression.)

  • Close-up of the "paw" print image. The impression was reportedly left by Bigfoot on the window of a pickup truck in the California Sierra National Forest over Memorial Day weekend 2011.

  • Bigfoot or bear? Pictured is a second impression left on the rear side window of the same truck from the previous slides. According to forensic/law enforcement photographer Mickey Burrow, "What you're seeing is a swipe mark. It looks like a small hand, swiping to the left, leaving another impression, and there's hair within those areas -- you can see where the hair would be."

  • This footprint was found over Memorial Day weekend, 2011, near Fresno, Calif. by a group of campers who were on a Bigfoot-hunting expedition. The print, measuring approximately 12 inches, was found near a truck where possible DNA evidence was left behind by more than one Bigfoot creature.

  • This footprint was found in 2008 in the Sierra National Forest near Fresno, Calif.
