Last week researchers from Oxford University and the Lausanne Museum of Zoology announced that they are seeking genetic materials (such as hair, skin, and blood samples) claimed to be of unknown animals such as Bigfoot. The goal of the Oxford-Lausanne Collateral Hominid Project is to catalogue and identify new species, including those long believed to be mythical.

Despite the publicity that the new project is garnering, this is far from the first time that alleged Bigfoot samples have been subjected to scientific testing.

In 2008, for example, the TV show "Destination Truth" recovered what was claimed to be a hair of a Yeti (formerly known as the Abominable Snowman). An analysis reportedly came back indicating that the sample contained "an unknown DNA sequence," though the full report was not made public and the results were never published in a journal -- as would be expected with a legitimate scientific discovery.

Then there was the strange case of a finger long claimed to be from a Yeti, once held in a monastery in Nepal which was examined by researchers at the Edinburgh Zoo last year. DNA testing solved the decades-old mystery and debunked the Yeti finger; it was actually human, probably from a monk.

For over a year Bigfoot buffs have followed the saga of Dr. Melba Ketchum, a veterinarian who claims to have definitive evidence of Bigfoot DNA. Ketchum says that her research will be published in a peer-reviewed scientific journal any time now, and has released virtually no information about her allegedly world-shaking findings, reminding those who question her that "until it is published, I cannot discuss our data at all."

Last week in a May 18 Facebook post, Ketchum once again promised that definitive Bigfoot DNA results would be published soon, and "that all is well and things are happening as expected."
