Sasquatch science

Bigfooters, people who search for evidence of the mythical creature Sasquatch, often use methods inspired by mainstream science, despite their claims being rejected by institutional science. Researchers conducted over 160 interviews with Bigfooters for their 2026 book, Bigfooters and Scientific Inquiry: On the Borderlands of Legitimate Science. The study found that Bigfooters are not anti-science but instead apply scientific principles like empiricism and methodology to their research. Unlike citizen scientists, who work within established scientific frameworks, Bigfooters operate outside mainstream science, valuing individual experience and anecdotal evidence, similar to natural philosophers of past centuries. For example, George Eberhart, a cryptozoologist and Bigfooter, stated that while Bigfooting is not part of mainstream science, it can still employ scientific methods to gather useful data.

Bigfooters argue that there is plenty of evidence for Sasquatch’s existence, such as thousands of witness testimonies, hundreds of footprint casts, and recorded howls or groans. However, they acknowledge that this evidence does not constitute proof, which would require a physical specimen or body. The scientific community and the public demand habeas corpus—a Latin term meaning 'you shall have the body'—to confirm Bigfoot’s existence. For instance, the 1960s Minnesota Iceman, a hairy humanoid encased in ice, was initially believed by some to be a genuine specimen but was later exposed as a hoax. This ongoing lack of a body has led to ethical debates among Bigfooters about whether to hunt for a specimen or rely on non-lethal methods.

The question of whether to kill a Bigfoot to obtain a specimen divides the community. Some, like anthropologist Grover Krantz, supported efforts to find and even kill a Bigfoot, offering money to researchers for assistance. Others, such as John Mionczynski, disagreed with this approach. Angelo Capparella of the North American Wood Ape Conservancy (NAWAC) argued that a physical specimen is necessary for scientific validation, stating, 'We’re going to be spinning our wheels forever if we don’t get a specimen.' Conversely, Craig Woolheater of the Texas Bigfoot Research Centre opposed killing, citing concerns about potentially endangering an unknown population. This debate highlights the tension between scientific curiosity and ethical considerations in Bigfooting.

Bigfooters face a paradox: despite thousands of reported encounters, no dead Bigfoot or even bones have been found. Some explain this by suggesting Bigfoot is an intelligent, social creature that carefully disposes of its dead, burying them deep or even consuming them. Todd Prescott, a Bigfooter, theorized that Bigfoot groups might bury carcasses 'six feet under' in remote locations, making discovery unlikely. Others argue that this absence itself supports the idea of Bigfoot’s intelligence and social behavior. However, skeptics point out that bear carcasses and bones are occasionally found in the wilderness, suggesting that if Bigfoot existed, their remains should also be detectable.

In the absence of a body, Bigfooters have turned to collecting hair samples as potential evidence. They claim that Sasquatch hair has distinctive features, such as a width of 60 to 90 micrometres, a round or egg-shaped root, and an imbricate scale pattern—a term describing the overlapping arrangement of microscopic structures on the hair shaft. Under a microscope, Bigfooter hair often lacks a central medulla (a core structure found in many animal hairs) and appears translucent. Zoologist Wolf Henner Fahrenbach supported the idea that such hair samples belong to an unknown primate. However, genetic analysis of these hairs has so far been inconclusive. For example, geneticist Bryan Sykes tested several 'Bigfoot' hair samples for the 2013 UK TV series Bigfoot Files and found they matched known mammals.

Bigfooters hope that genetic material from hair or other sources could provide definitive proof of Sasquatch’s existence. However, hair samples often lack a medulla, making DNA extraction difficult. Some Bigfooters, like Alex Solunac of the Vancouver Island Sasquatch Society, have abandoned hair analysis entirely, arguing that even unidentifiable samples do not necessarily prove Bigfoot’s existence. To overcome these challenges, Shelly Covington-Montana developed affordable wildlife DNA kits inspired by forensic and police methods. These kits aim to collect genetic material from sources like skin sebum (oily secretions) left behind when Bigfoot touches surfaces. Doug Hajicek, producer of the TV series MonsterQuest, suggested that chemical analysis of these sebum traces could reveal unique compounds, such as triglycerides and cholesterol, which differ among great apes, including humans.
