Bigfoot / Sasquatch
The name Sasquatch comes from a Sts’ailes word, printed in 1929. The name Bigfoot comes from tracks found in California in 1958. This case lists what the records show about both, from footprints and film to FBI and Oxford hair tests, and gives five explanations a fair hearing.
The question Is there an unknown ape living in North America’s forests, and what is the best evidence for and against it?

Maclean’s magazine prints Sts’ailes stories and introduces the word “Sasquatch”
J. W. Burns, a federal Indian agent working with the Chehalis band (now the Sts’ailes First Nation), published accounts of “hairy giants” told to him by community members. Sasquatch is an anglicised form of the Sts’ailes word sasq’ets.

The FBI laboratory tests hairs sent in as possible Bigfoot hair and finds they came from the deer family
Peter Byrne of the Bigfoot Information Center in Oregon asked the FBI to test about 15 hairs on a piece of skin. A memo of 22 February 1977 reports “a member of the deer family”. The FBI posted the file in June 2019, and Byrne told the Seattle Times he accepted the result.

An Oxford-led DNA study finds every “bigfoot” hair it could read came from a known animal
Of 18 US hair samples attributed to bigfoot, the matches were black bear (5), dog, wolf or coyote (4), cow (3), raccoon, horse, deer, porcupine, sheep and one human. The authors say this “cannot refute” an unknown primate but found no evidence for one.

Comparing the BFRO’s 2006 sighting reports with bear estimates across US states and Canadian provinces, and adjusting for people and forest area, it finds each extra 1,000 bears goes with about 4% more sightings: roughly one sighting a year per 5,000 bears.

“A real unknown ape, maybe a surviving Gigantopithecus”
Is Bigfoot a real ape unknown to science, perhaps a surviving Gigantopithecus?
Foxon’s 2024 paper notes that cryptozoologists who see Bigfoot as a surviving Ice Age ape call it “Gigantopithecus canadensis” (citing Heaney 1990). Earlier proposals by Grover Krantz and Geoffrey Bourne are reported elsewhere but were not read. Researcher Thomas Steenburg made the case to the BBC in 2022.

Footprint casts show anatomy that is hard to fake
Anatomist Jeff Meldrum keeps more than 200 casts and points to skin whorls and a flexible mid-foot: “with the footprints, I feel more certain.”
The premise: disputedThe casts exist and an expert reads them as a real primate. Other scientists reject them: Foxon’s paper cites critics who say “sweat pores” can be casting artefacts and prints can be enlarged.
T2Scientific American, Dec 2007T1Foxon, Journal of Zoology, 2024IntroductionThe 1967 film has never been proved a fake
The Los Angeles Times (2003): the film “has yet to be proved fake”. Foxon notes it was apparently not spliced or edited.

Bullshit meter
- Claim: Bigfoot is a surviving Gigantopithecus. Disproven.
- Key claim: an unknown ape lives in North America’s forests. Unverified.
- Key claim contradicted by tier 1? Partly. The Gigantopithecus version is contradicted by a 2024 Nature study dating its extinction, and every hair tested in 2014 came from a known animal. But no tier-1 record rules out an unknown ape, and the 2014 authors say their test cannot.
Fluff meter: possibly planted
- Can’t be traced to an original record. Absent: it points at real footprint casts, a real 1967 film and real sighting reports.
- First appeared from new or anonymous accounts. Not measured.
- Coordinated identical wording. Not measured.
- Cited source doesn’t exist. Not measured, but the FBI wrote in 1976 that it could not find the tests the 1975 atlas described.
- Later contradicted. Present for parts of it: the 2014 DNA study found only known animals, and the 2024 Nature study dates Gigantopithecus’s extinction.
