The Ketchum Bigfoot DNA study
In 2012–13 Texas veterinarian Melba Ketchum announced that DNA from over a hundred samples proved Bigfoot was a human hybrid; the paper appeared in a journal that Ketchum said her team had acquired and renamed.

The account
Ketchum's lab, DNA Diagnostics in Nacogdoches, issued a press release in November 2012 claiming a hybrid of modern humans and an unknown primate. Mainstream journals declined the paper, and it was published in February 2013 in 'DeNovo Journal of Science', whose website had been registered only days earlier and whose first issue held nothing else; critics noted it had no independent editorial board.
The sceptical view
Geneticists who looked at the data found contamination by human DNA and sequences from known animals such as bears and opossums. The study is not accepted by any genetic authority.
