Bigfoot: Evaluating Existence Through DNA
The scientific investigation of potential Bigfoot DNA has faced significant challenges within the academic community. DNA testing of purported Sasquatch samples has yielded intriguing results that warrant deeper examination. As a veterinarian with extensive genetics expertise and forensic experience, specialized testing protocols have been applied to over 100 samples allegedly connected to the cryptid commonly known as Bigfoot.
Multiple accredited laboratories conducted analyses on these samples through blind testing procedures. The samples were submitted without revealing their suspected origin, simply describing them as from "a tribe of humans." This approach eliminated potential bias in the testing process.
The DNA testing protocol included several verification methods:
Double-blind testing across different labs
Sample extraction at multiple facilities
Comparison testing for contamination control
Washing procedures to ensure sample purity
Several high-profile facilities participated in the analysis, including:
University of Texas
University of Southern California
Family Tree DNA
Texas A&M
Other laboratories (some requesting anonymity)
Some laboratories reported unusual findings in their analysis. One PhD researcher specifically noted in writing that the sequences weren't matching anything in genetic databases, questioning if a new species had been discovered. These responses came from scientists unaware of what they were actually testing.
The sample collection included both chain-of-custody verified specimens and those without formal documentation. While chain of custody remains important for certain scientific purposes, consistent morphological characteristics across samples suggested a common origin regardless of collection method. The hair samples displayed similar traits with minor variations in length and texture depending on body location.
Forensic expertise played a key role in excluding contamination as an explanation for the results. Unlike earlier university studies that dismissed unusual human-like DNA as contamination, the forensic approach applied contamination-control protocols typically used in crime scene analysis. These methods are designed to identify and account for mixed samples.
The study employed multiple extraction methods for verification. High-yield samples were processed at the primary lab, while low-yield samples underwent extraction at North Louisiana Criminalistics Laboratory using their robotic system. This dual-processing approach provided comparative data to address potential contamination concerns.
Work continues on the genome analysis with additional scientific collaborators. Due to concerns about professional backlash, these scientists have signed non-disclosure agreements allowing them the option to withhold their identities when findings are released.
Dr. Melba Ketchum's Professional Background
From Veterinary Practice to Genetics Research
Dr. Melba Ketchum began her career as a veterinarian after graduating from Texas A&M University. She practiced veterinary medicine until 1985, when she developed an allergy to cattle, which constituted approximately half of her practice. This medical condition necessitated a career change, leading her to explore opportunities in genetics. Her prior interest and aptitude in genetics, particularly equine genetics, influenced this transition.

DNA Evidence Study
The scientific research into potential undiscovered humanoid species has generated significant interest within both academic circles and the public domain. Advanced genetic testing procedures have been implemented to analyze various biological samples allegedly connected to cryptid sightings across North America and other global regions.
Scientific Research Challenges
The DNA analysis project faced numerous methodological hurdles that required careful scientific protocols. Over 100 samples underwent rigorous testing procedures at multiple facilities to ensure data integrity. The research team employed double-blind testing methods, with samples processed at two different laboratories before being sent to independent facilities for verification.
Hair specimens underwent morphological examination, revealing consistent characteristics despite variations in length and curl patterns. To prevent cross-contamination, forensic washing techniques were applied to all specimens, following standard crime scene evidence protocols. The research included both chain-of-custody samples and non-chain specimens, though the team prioritized documented samples including:

DNA Analysis Controversies
The genetic research triggered significant scientific backlash despite following established forensic procedures. When results indicated unusual human-like sequences, many laboratories expressed confusion or reluctance to be publicly associated with the findings. Some testing facilities threatened legal action if their names were disclosed after discovering what they had analyzed.
Several samples were sent to respected institutions including:
Institution Type of Testing Outcome University of Texas Genomic analysis Unidentified sequences University of Southern California DNA sequencing Anomalous results Family Tree DNA Mitochondrial DNA Non-matching patterns Texas A&M Comparative analysis Inconclusive identity
The research team faced significant academic opposition, with scientists refusing involvement unless protected by non-disclosure agreements. This reluctance stemmed from concerns about professional repercussions similar to those experienced by the lead researcher. The controversy has made continuing work challenging, despite efforts to maintain scientific integrity and peer review standards.
Research Methodology for Sasquatch DNA Analysis
Sample Collection and Preservation Protocols
Our research involved gathering and processing over 100 distinct biological specimens from various geographic locations across North America. Some samples maintained complete chain of custody documentation, while others were collected through citizen reports. While chain of custody proves valuable for forensic validation, the consistent biological profiles across specimens provided compelling evidence regardless of collection methods. Hair samples displayed consistent morphological characteristics despite variations in length and texture. Each specimen underwent preliminary screening to differentiate Sasquatch samples from known wildlife specimens such as bears and horses through expert hair analysis from an experienced mammalian hair analyst.
Independent Blind Testing Protocols
To eliminate researcher bias, we implemented rigorous blind and double-blind testing procedures. Laboratory technicians analyzing the samples received no information about the specimens' purported origins. In some cases, samples were processed at two separate facilities to verify consistency of results. The North Louisiana Criminalistics Laboratory, using state-of-the-art robotic extraction systems, processed all low-yield samples, while our primary facility handled higher-yield specimens. Select samples were deliberately processed without any contact from the principal investigators to further eliminate potential contamination or bias concerns.
Forensic-Grade Contamination Prevention
As a forensic laboratory with extensive experience handling mixed DNA samples from crime scenes, we implemented comprehensive anti-contamination protocols. These included:
Multiple washing procedures for each sample
Separate processing environments
Comparative analysis between different extraction methods
Duplicate testing to identify any procedural anomalies
Unlike academic laboratories that might discard unexpected results as contamination, our forensic approach anticipated and controlled for potential contamination scenarios. This methodology reflects standard practices in criminal investigations where maintaining sample integrity despite environmental challenges is paramount.
External Laboratory Verification Network
To validate our findings, specimens were distributed to multiple accredited external laboratories, including:
Institution Type of Analysis University of Texas Genomic sequencing University of Southern California DNA analysis Family Tree DNA Mitochondrial DNA sequencing Texas A&M University Genetic analysis
When submitting samples, we described them simply as "a newly discovered human tribe" without revealing their hypothesized origin. Several laboratories reported unexpected results, with one PhD researcher specifically noting in writing that the sequences failed to match any known entries in genetic databases, questioning if we had discovered a new species. Two additional laboratories that processed samples later requested anonymity after discovering the unusual nature of their results.
Engaging with Scientific Labs
Disguising the Research Materials
DNA samples collected for Sasquatch research required careful management during external testing. Over 100 specimens were submitted to various laboratories across the United States. To maintain scientific objectivity, researchers deliberately concealed the true nature of the materials. When sending samples to accredited facilities, they simply described them as belonging to "a tribe of humans that had been discovered," avoiding any mention of Bigfoot or similar cryptids.
The research team implemented rigorous forensic protocols to address potential contamination concerns. Both the primary laboratory and the North Louisiana Criminalistics Lab extracted samples using state-of-the-art techniques, including robotic systems for lower-yield specimens. In some cases, they employed double-blind methodologies, with samples extracted at two different laboratories to verify consistent results.
Expert Feedback from Unbiased Analysts
Scientists who examined the samples without knowledge of their purported origins provided intriguing responses. One PhD researcher documented in writing that the sequences didn't match anything in genetic databases, questioning whether a new species had been discovered. This assessment came from someone with no preconceived notions about the research subject.
Multiple prestigious institutions participated in the analysis, including:
University of Texas
University of Southern California
Family Tree DNA (one of the world's largest mitochondrial DNA labs)
Texas A&M University
Some laboratories reportedly threatened legal action if their names were associated with the findings after discovering what they had tested. Despite varying levels of chain-of-custody documentation for the samples, the consistent results across multiple independent laboratories suggested genuine findings. The forensic experts involved were accustomed to dealing with mixed samples and contamination issues in criminal cases, applying these same rigorous standards to this research.
Examination of Hair Morphology
Hair analysis serves as a crucial component in our species identification research. Morphological examination of hair samples collected from over 100 specimens revealed consistent characteristics across different geographical locations. These distinctive features help differentiate the subject species from known mammals.
The hair samples exhibited notable variations in length and texture depending on body location. Some samples appeared more curly than others, yet maintained fundamental morphological similarities that linked them as originating from the same species type.
Professional hair analysts with expertise in both human and animal hair identification for criminal cases examined these samples. Their specialized knowledge allowed for confident differentiation between the target samples and those from common mammals like bears or horses.
When samples were submitted to various laboratories for blind testing, experts consistently noted unusual characteristics. One PhD researcher specifically documented in writing that the sequences weren't matching anything in genomic databases, suggesting a potentially undiscovered species.
The washing procedures and contamination protocols applied were identical to those used in forensic analysis of crime scene evidence. This rigorous methodology ensured sample integrity despite varying collection circumstances.
While chain of custody documentation existed for some samples—including the Erickson Project specimens and those collected immediately following sightings—the consistency of morphological characteristics across all samples proved more significant for species identification purposes than collection methodology.
Hair morphology analysis formed just one part of a comprehensive testing approach that included extraction procedures at multiple facilities. The North Louisiana Criminalistics Lab handled lower-yield samples using state-of-the-art robotic systems, while higher-yield samples underwent processing at our primary facility.
Chain of Custody and Its Role in Sample Verification
Chain of custody plays a significant role in DNA analysis and species identification, though its importance can vary depending on research objectives. When collecting biological samples, maintaining proper documentation from collection to testing establishes credibility and reliability for scientific findings.
In forensic analysis, chain of custody documentation tracks sample possession, handling, and storage at every stage. This process helps verify sample integrity and addresses potential contamination concerns. For species identification studies, while chain of custody remains valuable, consistent results across multiple testing methods can sometimes compensate for incomplete documentation.
Proper sample handling techniques are essential regardless of documentation status. Forensic laboratories regularly implement contamination prevention protocols, including sample washing and purification steps. These procedures are particularly important when working with field samples that may contain mixed biological materials.
When sending samples to external laboratories, blind testing provides additional verification. This approach, where testing facilities receive no information about sample origins, eliminates bias and strengthens result validity. Double-blind testing, where samples are processed by multiple independent laboratories, further enhances reliability.
Sample Collection Best Practices:
Document collection circumstances and environmental conditions
Take photographs of collection site when possible
Record names of all individuals handling the sample
Use proper storage containers to prevent degradation
For research involving controversial or unusual subjects, rigorous methodology becomes even more critical. Multiple verification approaches help overcome skepticism, including:
Blind testing across multiple accredited laboratories
Sample extraction at different facilities
Comparative analysis of results across testing methods
Consultation with subject matter experts
DNA analysis experts recognize that contamination challenges exist in virtually all sample types. Forensic laboratories regularly work with samples from crime scenes where contamination is expected, developing expertise in distinguishing between target DNA and contaminants.
Physical characteristics of samples can provide supporting evidence beyond genetic testing. Consistent morphological features across multiple samples can reinforce conclusions about their origins, even when documentation varies in completeness.
Distinguishing Between Animal Species
The process of identifying different animal species through DNA and physical evidence requires significant scientific expertise. This field of study employs various techniques including genetic analysis and morphological examination to determine the origins of biological samples. The following sections explore the methodologies used in differentiating between species, particularly in cases of unusual or disputed evidence.
Analyzing Hair Samples
Hair analysis serves as a fundamental tool in species identification. When examining unknown hair specimens, forensic experts typically begin with morphological assessment before proceeding to genetic testing. A professional hair analyst with experience in both human and animal specimens can often make preliminary identifications based on physical characteristics alone.
DNA extraction from hair samples follows strict protocols to prevent contamination. Forensic laboratories routinely handle potentially mixed samples and employ specialized washing techniques to ensure sample integrity. This process is particularly critical when working with specimens collected from uncontrolled environments.
For reliable results, many research projects utilize multiple laboratory facilities to process the same samples independently. This double-blind approach helps validate findings and addresses potential concerns about contamination or procedural errors.
Separating Sasquatch Evidence from Other Animals
When investigating potential cryptid evidence, distinguishing between known animals and unidentified specimens requires rigorous scientific methodology. Hair samples attributed to possible unknown primates must be systematically compared against known species profiles through both physical and genetic analysis.
DNA Testing Protocols:
Initial screening at primary laboratory facility
Secondary verification at independent laboratories
Blind testing where analysts don't know the purported origin
Comparison against genetic databases (like GenBank)
Mitochondrial DNA analysis provides particularly valuable data for species identification. When samples don't match any known species in comprehensive databases, this suggests either contamination issues or potentially novel genetic profiles requiring further investigation.
The morphology of hair samples can provide consistent identifying characteristics across multiple specimens allegedly from the same species. While chain of custody documentation strengthens evidence quality, the genetic profile itself remains the most scientifically significant factor in determining taxonomic classification.
Scientific examination of unusual biological samples faces unique challenges, including both technical difficulties and potential professional consequences for researchers who pursue controversial topics. This reality often necessitates additional verification steps beyond standard scientific protocols.
Public Perception and Scientific Research Challenges
The scientific community often responds with skepticism when unconventional research challenges established paradigms. Dr. Melba Ketchum's DNA study on potential unidentified humanoid species illustrates this phenomenon. As a veterinarian with extensive genetics expertise, Dr. Ketchum had established credibility among peers, serving in leadership positions for the International Society for Animal Genetics and a national forensic association before her controversial research.
Scientific reception changed dramatically once her research focused on potential Sasquatch DNA evidence. The research team implemented rigorous scientific protocols, including:
Double-blind testing procedures
Sample extraction at two different laboratories
Distribution to multiple accredited facilities
Anti-contamination measures standard in forensic analysis
Despite these precautions, the scientific establishment's response was severe enough that subsequent researchers working on similar genomic studies required non-disclosure agreements to protect their careers. This reflects a concerning pattern where scientific inquiry into certain topics faces extraordinary barriers regardless of methodology quality.
The team analyzed over 100 samples using multiple respected laboratories including University of Texas, University of Southern California, and Family Tree DNA. Some testing facilities reportedly threatened legal action if their involvement became public after discovering what they had analyzed.
Hair morphology consistency across samples provided additional supporting evidence beyond DNA analysis. A professional hair analyst who routinely examines both animal and human samples for criminal cases assisted in distinguishing these specimens from known species.
This case demonstrates how scientific exploration can become politically charged when findings challenge conventional understanding, potentially limiting open inquiry even when following established scientific protocols.
