Bigfoot at 50: Evaluating a half-century of Bigfoot evidence

4. Somatic Samples

Hair and blood samples have been recovered from alleged Bigfoot encounters. As with all the other evidence, the results are remarkable for their inconclusiveness. When a definite conclusion has been reached, the samples have invariably turned out to have prosaic sources--"Bigfoot hair" turns out to be elk, bear, or cow hair, for example, or suspected "Bigfoot blood" is revealed to be transmission fluid. Even advances in genetic technology have proven fruitless. Contrary to popular belief, DNA cannot be derived from hair samples alone; the root (or some blood) must be available.

In his book Big Footprints, Grover Krantz (1992) discusses evidence for Bigfoot other than footprints, including hair, feces, skin scrapings, and blood: "The usual fate of these items is that they either receive no scientific study, or else the documentation of that study is either lost or unobtainable. In most cases where competent analyses have been made, the material turned out to be bogus or else no determination could be made" (125). He continues, "A large amount of what looks like hair has been recovered from several places in the Blue Mountains since 1987. Samples of this were examined by many supposed experts ranging from the FBI to barbers. Most of these called it human, the Redkin Company found significant differences from human hair, but the Japan Hair Medical Science Lab declared it a synthetic fiber. A scientist at [Washington State] University first called it synthetic, then looked more closely and decided it was real hair of an unknown type.... Final confirmation came when E.B. Winn, a pharmac eutical businessman from Switzerland, had a sample tested in Europe. The fiber was positively identified as artificial and its exact composition was determined: it is a product known commercially as Dynel, which is often used as imitation hair." In his analysis, Winn (1991) noted that another alleged Bigfoot sign found at the site, tree splintering, had also been faked.

Hoaxes, the Gold Standard, and the Problem of Experts

Such hoaxes have permanently and irreparably contaminated Bigfoot research. Skeptics have long pointed this out, and many Bigfoot researchers freely admit that their field is rife with fraud. This highlights a basic problem underlying all Bigfoot research: the lack of a standard measure. For example, we know what a bear track looks like; if we find a track that we suspect was left by a bear, we can compare it to one we know was left by a bear. But there are no undisputed Bigfoot specimens by which to compare new evidence. New Bigfoot tracks that don't look like older samples are generally not taken as proof that one (or both) sets are fakes, but instead that the new tracks are simply from a different Bigfoot, or from a different species or family. This unscientific lack of falsifiability plagues other areas of Bigfoot research as well.

Bigfoot print hoaxing is a time-honored cottage industry. Dozens of people have admitted making Bigfoot prints. One man, Rant Mullens, revealed in 1982 that he and friends had carved giant Bigfoot tracks and used them to fake footprints as far back as 1930 (Dennett 1996). In modern times it is easier to get Bigfoot tracks. With the advent of the World Wide Web and online auctions, anyone in the world can buy a cast of an alleged Bigfoot print and presumably make tracks that would very closely match tracks accepted by some as authentic.
