Ketchum Bigfoot DNA Study to be Published


The peer review process of the Bigfoot DNA study lead by Dr. Melba Ketchum has been completed. A statement was made by Dr Ketchum confirming that it had passed the peer review process and will be published by the DeNovo Scientific Journal. Here is the statement made by Dr. Ketchum from here facebook page ” It is not how it seems. There will be a statement in the morning explaining why it is the first paper. I had NOTHING to do with the peer review and it was blind (I was not told who they were) as it is supposed to be and we did pass. The reviewers were geneticists with next gen whole genome experience. That was all I was told by the editor.”



Here is the synopsis:


New Research Paper Published Friday Shows Homo Sapiens/Unknown Hominin Hybrid Species Extant in North America
DALLAS, February 10th

A team of scientists will publish their five-year long study of DNA samples from a novel hominin species, commonly known as “Bigfoot” or “Sasquatch,” on Friday February 15th, 2013. The results suggest that the legendary Sasquatch is extant in North America and is a human relative that arose approximately 13,000 years ago as a hybrid cross of modern Homo sapiens with an novel primate species.

The study, “Novel North American Hominins, Next Generation Sequencing of Three Whole Genomes and Associated Studies,” was conducted by a team of experts in genetics, forensics, imaging and pathology. The team, led by Dr. Melba Ketchum of DNA Diagnostics in Nacogdoches, TX, included Dr. Pat Wojtkiecicz, Director of the North Louisiana Criminalistics Laboratory; Ms. Aliece Watts of Integrated Forensic Laboratories in Euless, TX; Mr. David Spence, Trace Evidence Supervisor at Southwestern Institute of Forensic Sciences; Dr. Andreas K. Holzenburg, Director of the Microscopy & Imaging Center at Texas A&M University; Dr. Douglas G. Toler of Huguley Pathology Consultants in Fort Worth, TX; Dr. Thomas M. Prychitko of Wayne State University in Michigan; Dr. Fan Zhang of the University of North Texas Health Science Center; and Sarah Bollinger, Ray Shoulders, and Ryan Smith of DNA Diagnostics.

In total, 110 specimens of purported Sasquatch hair, blood, skin, and other tissue types were analyzed for the study. Samples were submitted by individuals and groups at 34 different hominin research sites in 14 U.S. states and two Canadian provinces. Ketchum’s team sequenced 20 whole and 10 partial mitochondrial genomes, as well as 3 whole nuclear genomes, from the samples.

Mitochondrial DNA (mtDNA) comes from mitochondria, energy-producing organelles in the cellular cytoplasm, and is passed down on the maternal lineage across generations. Nuclear DNA (nuDNA) is the genetic information contained in the cell nucleus and is the equal combination of DNA from the parents of an individual.

Initially a skeptic, Ketchum implemented strict protocols to ensure the scientific integrity of the study. DNA samples from submitters and scientists working with study specimens were obtained for use as controls. DNA was extracted from samples using forensic procedures to prevent contamination. Forensics experts examined the morphology of the submitted hair samples against known human and animal samples before beginning DNA testing. “We soon discovered that certain hair samples–which we would later identify as purported Sasquatch samples–had unique morphology distinguishing them from typical human and animal samples,” says Ketchum. “Those hair samples that could not be identified as known animal or human were subsequently screened using DNA testing, beginning with sequencing of mitochondrial DNA followed by sequencing nuclear DNA to determine where these individuals fit in the ‘tree of life.’”

After extensive forensic controls to prevent contamination, mtDNA testing of the Sasquatch samples yielded fully modern human profiles. Sixteen haplotypes indicating 100% homology with modern human mtDNA sequences were observed from 20 completed whole and 10 partial mitochondrial genomes. The human mtDNA results are consistent with prior, unrelated mtDNA tests of purported Sasquatch samples from other laboratories.

Next-generation whole genome sequencing with the HiSeq 2000 platform by Illumina was performed at the University of Texas, Southwestern on one tissue sample, a saliva sample and one blood sample to produce 3 whole genomes. In contrast to the mtDNA which was unambiguously modern human, the Sasquatch nuDNA results were a mosaic of novel primate and human sequence.

“While the three Sasquatch nuclear genomes aligned well with one another and showed significant homology to human chromosome 11 which is highly conserved in primates, the Sasquatch genomes were novel and fell well outside of known ancient hominin as well as ape sequences,” explains Ketchum. “Because some of the mtDNA haplogroups found in our Sasquatch samples originated as late as 13,000 years ago, we are hypothesizing that the Sasquatch are human hybrids, 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.

Specimens yielding DNA were obtained, purportedly from elusive hominins in North America




  1. Bigfoot Believer says

    I was pleased when I became aware of the ongoing DNA research that was underway and the new groundbreaking efforts that were being made by Dr. Melba Ketchum in Texas. I followed the numerous websites and radio interviews that were commenting about this research, and was very gladdened by the December 24th Coast to Coast AM Interview with Dr. Ketchum.

    I had taken note of the fact that numerous highly opinionated individuals, who are Skeptics, had almost always made deleterious comments to the effect that the DNA findings must be flawed by some form of contamination for the resrearch to have shown the presence of Human Mitochondrial DNA.
    Dr. Ketchum spoke in reply to the matter of sample contamination many times, and detailed the efforts that were being made to forestall that problem. the Skeptics were obviously not listening clearly, because they continued to rail that there absolutely must have been contamination of the DNA Samples that were used in this Study, all 109 of them.

    The true facts seem to be that an enormous amount of care had been taken by Dr. Melba Ketchum and her highly skilled associates, who used State of the Art Forensic Techniques to prevent even the remotest possibility of that happening, and my reading of the Study confirmed the rather obvious conclusion that most of the skeptics had unquestionably jumped to their conclusions without any real factual evidence, as usual.

    The work done by the University of Texas Southwestern at Dallas has revealed that the three samples that Dr. Kertchum had submitted for Nuclear DNA sequencing were of very high quality, and highly purified, and capable of providing valid results using the Illumina Next Generation Sequencing Platform, with a statistical probability greater than 1:1000 of being correctly sequenced.
    Obviously these were not “Contaminated Samples”

    TAKE NOTICE OF THE FOLLOWING INFORMATION, As reported in the PRweb Seattle WA at

    “The team, led by Dr. Melba S. Ketchum, DVM, of DNA Diagnostics in Nacogdoches, TX, submitted a tissue sample, a saliva sample, and a blood sample to the DNA Laboratory at the University of Texas, Southwestern, who then sequenced the Three whole Nuclear Genomes using the Next-Generation Illumina HiSeq 2000 Platform. The University lab reported that the three genomes all attained Q30 quality scores above 88 on the Illumina platform, which is significantly higher than the platform average of 85, indicating highly-purified, single-source DNA with no contamination for each sample. The three Sasquatch genomes were reported to align well with one-another and show substantial homology to primate sequences.”

    NOTE: The important fact to observe is that the three Q30 Scores of these three Genomes, with over 90 Gb of Raw seqence for each sample, (Comprising greater than 30x coverage), were 88.6, 88.4 and 88.7 respectively. The Q30 is the percent of reads that have the statistical probability greater than 1:1000 of being correctly sequenced. According to Illumina, a pure single source sample would have a Q30 score of 80 or greater, with an average Q30 score of 85. Contaminated or multiple source samples would have Q30 scores of 40 to 50.

    Therefore, not only were the three samples that were submitted for sequencing each determined to be totally UNCONTMINATED and were from a single source, and the resultant quality of the sequences that were obtained from them were FAR ABOVE the average 85 score of the Genomes sequenced using the Illumina Next Generation Sequencing Platform at the UNIVERSITY OF TEXAS Southwestern in Dallas, Texas. A Further comment made about the samples was: “The high quality of the Genomes can be attributed to the STRINGENT EXTRACTION PROCEDURES UTILIZED WHEREBY THE DNA WAS REPEATEDLY PURIFIED”. Dr. Ketchum obviously did a good job of providing high quality samples that were capable of providing valid results.

    NOTE: It would appear that the University of Texas Southwestern’s DNA Laboratory is rather sure that these are good Genomes, and that they were tested to be of very high quality. How could you ask for much more than that? One Genome would be more adequate to prove the existence of a new species.
    Three is OVERKILL. It is time for the Skeptics to admit that they were WRONG!
    It is a NEW Species.

    You will not be able to find any qualified Geneticist who can argue with the spectacular results produced by the UNIVERSITY OF TEXAS DNA Labaoratory. Those were very good Q30 scores.

    New species have been accepted by Science with as little as 16 KB. Just a very small number of base pairs. The sample size here was 90 Gb for each of three samples. See the Supplementary Data 7-10 in the Article. There were at least 2.7 Million Base Pairs that were analyzed and studied, much more than what is needed to prove the existence of a new species.

    I believe that this groundbreaking DNA Study was done with very great care and that the resultant findings are now thoroughly capable of proving to even the most diehard, outspoken Skeptics, that there is incontrovertible PROOF that there is an unclassified Hominin roaming North America.
    This evidence is backed up by the substantial work that has been done at instituions like The University of Texas at Dallas, Texas A & M University, and several other academic institutions and Professional Laboratories.

    Dr. Ketchum and her esteemed colleagues are to be heartily commended for the dedication that they have shown in the face of derision from the mass attacks by huge numbers of Naysayers, Skeptics and Fools.

    I urge everyone, and especially hardcore Skeptics to take the time to read this amazing DNA Study and to become aware of the incredible quality of the Science behind it.

    Being a skeptic does not require that you cannot accept valid Scientific studies, that are done with a great deal of care and appropriate attention to detail by highly skilled professionals, at highly accredited institutions of Higher Learning!

    My kudos to the BRAVE DNA researchers who refused to give up and quit. They will go down in History!
