The most scrutinized physical traces attributed to Bigfoot are hair samples, plaster casts of large footprints, and a few videos/photographs — with hair DNA tests repeatedly tracing samples to known a...
The scientific record to date contains no confirmed Bigfoot (or other “relict hominoid”) DNA: systematic peer‑reviewed studies that analyzed dozens of hair samples identified only known species or hum...
Two systematic mitochondrial-DNA (mtDNA) surveys of alleged Bigfoot/yeti hairs dominate the literature: Bryan Sykes’ Oxford–Lausanne team sequenced the 12S mitochondrial rRNA from 30 hairs and identif...
Mitochondrial 12S RNA sequencing has identified known species in the majority of hair samples submitted as “Bigfoot” or other anomalous primates: of 57 submitted hairs, DNA was recovered from 30 and e...
Multiple systematic studies of alleged Bigfoot/Yeti samples have found mitochondrial (maternal-line) sequences that match modern humans or known animals, and in peer-reviewed work none of the mitochon...
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 co...
