'Bigfoot' Is Part Human, DNA Study Claims

Genetic testing confirms the legendary Bigfoot is a human relative that arose some 15,000 years ago at least according to a press release issued by a company called DNA Diagnostics detailing supposed work by a Texas veterinarian.

The release and alleged study by Melba S. Ketchum also suggests such cryptids had sex with modern human females that resulted in hairy hominin hybrids, but the scientific community is dubious about her claim.

"A team of scientists can verify that their five-year long DNA study, currently under peer-review, confirms the existence of a novel hominin hybrid species, commonly called 'Bigfoot' or 'Sasquatch,' living in North America," the release reads. "Researchers' extensive DNA sequencing suggests that the legendary Sasquatch is a human relative that arose approximately 15,000 years ago."

For her study, Ketchum obtained three "whole nuclear genomes from purported Sasquatch samples. The genome sequencing shows that Sasquatch mtDNA is identical to modern Homo sapiens, but Sasquatch nuDNA is a novel, unknown hominin related to Homo sapiens and other primate species." (Mitochondrial DNA, or mtDNA, is the DNA that resides in the cell's energy-producing structures, and is typically passed down from mothers, while nuclear DNA, nuDNA, resides in the cells' nuclei and is passed down from both parents to offspring.)

"Our data indicate that the North American Sasquatch is a hybrid species, the result of males of an unknown hominin species crossing with female Homo sapiens," the statement reads. [Infographic: Tracking Belief in Bigfoot]

Any proof?

It's a fascinating theory.

So where's the evidence? Well, there is none. Not yet, anyway: Ketchum's research has not appeared in any peer-reviewed scientific journal, and there's no indication when that might happen. If the data are good and the science is sound, any reputable science journal would jump at the chance to be the first to publish this groundbreaking information. Until then, Ketchum has refused to let anyone else see her evidence.

Of course the history of Bigfoot is rife with exaggerated and premature claims about proof of the creature's existence. For decades, various types of evidence have been offered as final, definitive proof, ranging from Bigfoot hair to blood to dead bodies. Without exception, the evidence has always been hoaxed, misidentification or inconclusive.

Because Ketchum has released no information at all about her findings (nor have they been examined by outside experts), it's impossible to evaluate the validity of her conclusions. But an important clue can be found in her statement that "Sasquatch mtDNA is identical to modern Homo sapiens."
