Executive summary

Reputable scientists and institutions have occasionally tested alleged Bigfoot physical evidence—most notably genetic analyses of hair samples and forensic examinations of footprints—but mainstream conclusions have been skeptical: many tested samples turned out to be known animals, contaminants, or inconclusive, and claims of a confirmed hominin have not passed peer review [1] [2] [3] [4]. A few academics (for example Jeff Meldrum, Grover Krantz) have investigated footprints and other traces, and some independent labs and groups (including the Sasquatch Genome Project led by Melba Ketchum) have produced affirmative claims that have been widely criticized by mainstream scientists and science journalists [5] [6] [4] [7].

1. Laboratory DNA work: Oxford-led peer-reviewed study that mostly ID’d known species

An Oxford-affiliated team led by geneticist Bryan Sykes published what Science described as “the first peer-reviewed genetic analysis” of more than 50 purported Bigfoot/yeti hair samples; the group received 57 submissions, focused on 37 hairs, and found many samples were plant or glass fibers or contaminated, but followed standard protocols to reduce contamination—experts cited praised the approach even as results tended to identify known species rather than an unknown hominin [1]. Science and Science News coverage framed this as a proper scientific step that mostly undercut cryptid claims by returning familiar species or degraded materials [1] [2].

2. The FBI hair analysis: agency examined hairs, concluded deer family origin

Federal involvement exists: the FBI opened and later declassified a “Bigfoot file” that includes a 1977 laboratory correspondence concluding certain hairs were of deer family origin; the bureau’s documents do not endorse Bigfoot but record an identification of those samples as non-hominin [3]. The History summary stresses that agency analyses were routine identifications, not validation of a cryptid species [3].

3. Academic primatologists and anthropologists: interest, limited acceptance

Some credentialed academics have engaged the question. Anthropologist Jeff Meldrum (Idaho State University) has studied casts and footprints and has argued some track evidence merits scientific attention; NPR’s profile notes Meldrum’s effort to treat evidence in a conventional zoological framework while acknowledging the lack of a type specimen [5]. Wikipedia’s survey of historical interest lists scientists who have shown varying degrees of engagement—Grover Krantz, Jeffrey Meldrum, John Napier among them—but also records mainstream scientists’ view that the evidence is insufficient [6].

4. Independent and private projects: positive claims, contested methods

Private projects have made strong claims. The Sasquatch Genome Project and DNA Diagnostics Inc. (Melba Ketchum) publicly claimed to have sequenced a novel hominin and argued for a human-hybrid origin for Sasquatch; media coverage and science reporters criticized the process for lack of peer-reviewed publication and questioned lab methods and interpretation [4] [7]. CNBC and ABC News reported the group’s announcements, while science journalists and mainstream geneticists described those results as “junk science” or premature because they were not vetted via accepted peer review channels [4] [7].

5. Forensic footprint analysts and law-enforcement experts: some convinced, others skeptical

Forensic footprint specialists like Jimmy Chilcutt have reviewed large collections of casts and sometimes pronounce individual tracks compelling; National Geographic described Chilcutt’s analysis of over 150 casts held by Meldrum and said one print convinced him of an anomalous origin [8]. At the same time, the literature and skeptics note widespread instances of hoaxed prints and misidentifications, and mainstream scientists emphasize that eyewitness and cast evidence alone is not sufficient to establish a new species [8] [9].

6. Mainstream scientific consensus and statistical critiques: no solid evidence so far

Science coverage, Smithsonian and Live Science reviews, and statistical analyses argue that the balance of evidence does not support a large unknown North American hominid: many alleged materials resolve to known species or contaminants, no bodies or fossils have been produced, and some statistical work correlates sightings with bear populations—suggesting misidentification is a plausible explanation [1] [9] [10] [2]. Science News and other outlets praised rigorous genetic testing even when it disconfirmed enthusiasts’ hopes, noting that peer‑reviewed negative results still advance knowledge [2].

7. What is and isn’t in the reporting: limits and divergent agendas

Available sources show reputable labs and named scientists have tested Bigfoot evidence, but most independent groups that claim positive proof have been criticized for bypassing peer review or using questionable methods [1] [4] [7]. Cryptozoology organizations and some researchers clearly have an advocacy agenda toward proving cryptids (e.g., BFRO, Sasquatch Genome Project), while mainstream scientists and science journalists prioritize standard peer review and reproducible identification of samples [11] [2] [4].

8. Bottom line for the reader: what the evidence presently supports

Current, verifiable laboratory and forensic work cited in mainstream outlets mostly identifies alleged Bigfoot physical evidence as known animals, contaminants, or inconclusive, and extraordinary claims of a novel hominin have not been substantiated in peer‑reviewed, widely accepted scientific literature [1] [3] [2] [4]. If you want to follow claims, prioritize results that have clear methods, transparent data, and publication in peer-reviewed venues—those are the criteria mainstream scientists repeatedly cite [1] [2].
