Pseudoscience: Siberian Yeti

Bigfoot Hunters Detect Signs of the Hairy Beast in Siberia

The Siberian Yeti

1) The Siberian yeti is an example of pseudoscience because of the fact that despite several people claiming to have seen him, no legitimate scientific evidence of his existence actually exists (i.e. DNA, physical measurements after being captured by legitimate scientists, etc.). People have offered some evidence such as footprints and photographs of the creature, but most of the evidence is circumstantial at best or doctored. The idea of a "yeti" falls under the concept of cryptozoology, an area of pseudoscience that encompasses creatures that are considered not to exist by most biologists. Since most biologists refuse to accept the idea of the yeti's existence, it is generally considered only a myth.
2) The only possible legitimate scientific claims are the small pieces of evidence that others have found (i.e. footprints, cave abodes with beds made of brush, broken branches indicating a yeti trail, hairs, and grainy photographs of the yeti) and the fact that no one can refute his existence (but that is a logical fallacy, so that does not really count). However, most of these are either doctored, not upheld by scientific review, or tracks made by other animals so their legitimacy is more-or-less baseless.
3) The fact that the yeti has never been seen by anyone other than the so-called witnesses makes their overall claim suspicious and difficult to support. Unless a group of biologists actually captures the creature, analyzes it, and determines that it is not just a bear that has learned to walk on its hind legs, then the yeti cannot be considered real. Actual DNA evidence would also make the claims easier to believe. The only physical evidence of the yeti that has ever been found was hair (and a scalp), but scientists have not verified these findings as unique to a creature like the yeti.
4) The reason why people may fall for this claim is the same reason why people fall for any pseudoscientific claim. The idea of a mysterious, Neanderthal-like creature walking around the wilderness available for capture by any individual with the means, patience, and manpower to accomplish such a task is the same kind of idea that compels others to search for El Dorado or the Bermuda Triangle. Only a small percentage of people actually believe the evidence presented by cryptozoologists, but there are others who generally believe these kind of phenomenon due to their mystique and appeal to people's beliefs in the supernatural or strange things.
