Frame 352 from the Patterson-Gimlin film, alleged by Roger Patterson and Robert Gimlin to show a Bigfoot, and by some others to show a man in an ape suit.

The team, led by Dr. Melba S. Ketchum, DVM, of DNA Diagnostics in Nacogdoches, TX, sequenced the three whole nuclear genomes using the next-generation Illumina HiSeq 2000 platform at University of Texas, Southwestern from a tissue sample, a saliva sample, and a blood sample. The three genomes all attained Q30 quality scores above 88 on the Illumina platform, significantly higher than the platform average of 85, indicating highly-purified, single-source DNA with no contamination for each sample. The three Sasquatch genomes align well with one-another and show substantial homology to primate sequences.

In addition to the three nuclear genomes, Ketchum’s team also sequenced 20 whole and 10 partial mitochondrial genomes from the Sasquatch samples. In contrast to the nuDNA results, the Sasquatch mtDNA was fully modern Homo sapiens, indicating that the species is a hybrid cross between modern Homo sapiens in the maternal lineage and an unknown hominin male progenitor.The paper is entitled “Novel North American Hominins, Next Generation Sequencing of Three Whole Genomes and Associated Studies.”  by authors: Ketchum MS, Wojtkiewicz PW, Watts AB, Spence DW, Holzenburg AK, Toler DG, Prychitko TM, Zhang F, Bollinger S, Shoulders R, Smith R.  DeNovo. 13 February 2013.Specimens yielding DNA were obtained, purportedly from elusive hominins in North America called Sasquatch. Sequencing and genotyping were performed in addition to histopathologic and electron microscopic examination of a large tissue sample.

Mitochondrial whole genomes were consistent with modern humans. In contrast, novel data were obtained when nuclear DNA was sequenced. Next generation whole genome sequencing was performed on three samples. Phylogeny trees generated showed homology to human chromosome 11 and to primate sequences. The data indicates that the Sasquatch has human mitochondrial DNA but possesses nuclear DNA that is a structural mosaic consisting of human and novel non-human DNA.

The team of scientists can verify that their 5-year long DNA study confirms the existence of a novel hominin hybrid species, commonly called “Bigfoot” or “Sasquatch,” living in North America. Researchers’ extensive DNA sequencing suggests that the legendary Sasquatch is a human relative that arose approximately 15,000 years ago as a hybrid cross of modern Homo sapiens with an unknown primate species.The study was conducted by a team of experts in genetics, forensics, imaging and pathology, led by Dr. Melba S. Ketchum of Nacogdoches, TX. In response to recent interest in the study, Dr. Ketchum can confirm that her team has sequenced 3 complete Sasquatch nuclear genomes and determined the species is a human hybrid:“Our study has sequenced 20 whole mitochondrial genomes and utilized next generation sequencing to obtain 3 whole nuclear genomes from purported Sasquatch samples. The genome sequencing shows that Sasquatch mtDNA is identical to modern Homo sapiens, but Sasquatch nuDNA is a novel, unknown hominin related to Homo sapiens and other primate species. Our data indicate that the North American Sasquatch is a hybrid species, the result of males of an unknown hominin species crossing with female Homo sapiens.

Hominins are members of the taxonomic grouping Hominini, which includes all members of the genus Homo. Genetic testing has already ruled out Homo neanderthalis and the Denisova hominin as contributors to Sasquatch mtDNA or nuDNA. “The male progenitor that contributed the unknown sequence to this hybrid is unique as its DNA is more distantly removed from humans than other recently discovered hominins like the Denisovan individual,” explains Ketchum.

“Sasquatch nuclear DNA is incredibly novel and not at all what we had expected. While it has human nuclear DNA within its genome, there are also distinctly non-human, non-archaic hominin, and non-ape sequences. We describe it as a mosaic of human and novel non-human sequence. Further study is needed and is ongoing to better characterize and understand Sasquatch nuclear DNA.”

Ketchum is a veterinarian whose professional experience includes 27 years of research in genetics, including forensics. Early in her career she also practiced veterinary medicine, and she has previously been published as a participant in mapping the equine genome. She began testing the DNA of purported Sasquatch hair samples 5 years ago.

Ketchum calls on public officials and law enforcement to immediately recognize the Sasquatch as an indigenous people:

“Genetically, the Sasquatch are a human hybrid with unambiguously modern human maternal ancestry. Government at all levels must recognize them as an indigenous people and immediately protect their human and Constitutional rights against those who would see in their physical and cultural differences a ‘license’ to hunt, trap, or kill them.”
