A team of American researchers has claimed that "Bigfoot" was a real creature and also revealed that DNA samples showed it had sex with human females more than 15,000 years ago.
Texan veterinarian-researcher Melba S. Ketchum and her firm DNA Diagnostics worked for five years, and concluded that the mythic Bigfoot is indeed a human hybrid that descended from human women who mated with men of "an unknown hominin species", the Daily Mail reported.
However, Ketchum has presented no evidence yet for her findings, nor has she had her work reviewed by peers, the daily said.
Ketchum said mitochondrial DNA in the samples, which she apparently obtained from leftover blueberry bagels eaten by a family of 10 bigfoots who lived in Michigan, show clear evidence of genetic mixing.
Scientists have demanded that Ketchum present her evidence but she has so far declined to make anything public.
If her study is proven, it would suggest two options for scientists -- one that Bigfoot did have sex with ancient human women 15,000 years ago, and created a half-human hybrid species which is currently hiding in North America, and another is that the samples are contaminated.
Ketchum said the US government should immediately recognise Bigfoot as "an indigenous people and immediately protect their human and Constitutional rights".
