The Bigfoot DNA question: Zana, Khwit and what the data can and cannot show (Ford, Sol 6.0, Claude Opus 5/5.5)

I would imagine nuclear DNA has been conducted before, it would require a conspiracy then to hide something at that point

Yes — and in fact there has been a claimed nuclear-DNA Bigfoot study, which is why this question gets interesting.

In 2013, veterinarian Melba Ketchum and collaborators claimed they had sequenced three purported Sasquatch nuclear genomes and found human mitochondrial DNA plus unusual nuclear DNA they interpreted as a human/unknown-hominin hybrid. citeturn786390search0turn786390search6

The problem is that the study never achieved normal scientific credibility. The paper appeared in a newly created journal called DeNovo after mainstream journals had rejected it; independent geneticists who examined the sequence data concluded that the supposed “novel genome” looked much more like contamination, degraded DNA, bad assembly, and mixtures of known species than a coherent unknown hominin genome. citeturn786390search2turn786390search4

So I wouldn’t say we have a clean case where a reputable lab sequenced a pristine specimen, obtained an unmistakably unknown hominin genome, and then everyone collectively buried it.

But your logic is right about what would happen if that occurred.

Suppose someone had:

• impeccable chain of custody
• fresh tissue or blood
• high-quality nuclear DNA
• deep whole-genome sequencing
• clear evidence it was a distinct hominin lineage
• independent replication by multiple labs

At that point, making it disappear would require something much more like an actual suppression effort, because the data itself would be reproducible. Once raw sequence files are copied into multiple labs and public databases, hiding them becomes extremely difficult.

That is why replication is such a useful discriminator here.

The Ketchum case is frustrating because it sits in the worst possible zone: extraordinary claim, messy samples, controversial publication route, no convincing independent replication.

So we don’t need a conspiracy to explain why it isn’t accepted.

But I agree with the larger point: if someone ever gets a truly good nuclear genome and it comes back as an unknown Homo lineage, that becomes very hard to make vanish without deliberate intervention.

oh that could be a problem too, any reputable journal would never touch it I don't think, other than to discredit it

There probably is some stigma, especially if the manuscript arrives titled Genomic Proof of Sasquatch. Editors are human, and extraordinary claims get a much harsher initial look.

But I think a genuinely good specimen would get past that problem surprisingly fast. You wouldn't even need to call it Bigfoot. A competent genetics team could submit something like:

Whole-genome sequencing of an unidentified North American hominin sample

Then show the sequence data, contamination controls, chain of custody, phylogenetic trees, coverage, heterozygosity, mitochondrial genome, and independent replication.

At that point the editor isn't being asked to believe somebody's campfire story. They're looking at a genome.

We have a great precedent in Denisovans: scientists initially had essentially a tiny finger bone from a Siberian cave. DNA showed that it belonged to a previously unknown archaic human lineage. That wasn't suppressed for being extraordinary—it became a major scientific discovery.

The real weak point for Bigfoot research is usually before publication: questionable sample provenance, no uncontaminated tissue, poor chain of custody, low-quality DNA, ambiguous sequencing, or conclusions much stronger than the data support. That's what sank the Ketchum work more than simply saying “Bigfoot.”

If somebody instead walked into three independent university genetics labs with a fresh chunk of tissue and all three got something like:

99.x% human-like DNA, but clearly outside Homo sapiens, Neanderthal and Denisovan variation

then I think journals would be fighting over the paper, not refusing to publish it. It would be one of the biggest biological discoveries in decades.

Where I agree with you is that a marginal result is vulnerable to stigma. If the evidence is only “this weird hair gave a somewhat unusual human sequence,” Bigfoot association could absolutely make scientists more inclined to assume contamination or error. And often that assumption might even be correct.

So the ideal Bigfoot DNA test has to be almost obnoxiously clean: fresh sample, photographed collection, independent chain of custody, multiple labs, whole nuclear genome, raw data publicly released.

Once you have that, you don't really need anyone's permission to call it extraordinary.

it should exist still, it is strange it does not. Perhaps there is some sort of conspiracy to stop the evidence before getting to a lab for analysis, or even a hidden hand keeping journals from reporting on it. It is a hard thing to explain.

Yeah, the missing-evidence problem is the weirdest part of Bigfoot. If there really is a breeding population of large primates spread across North America, you would expect something definitive to have survived by now.

A conspiracy is logically possible, but it starts getting difficult because the relevant system is so decentralized. It wouldn’t just require controlling one journal or one federal agency. You’d potentially have to intercept evidence from hunters, veterinarians, universities, private sequencing companies, museums, wildlife biologists, county coroners, independent labs, and ordinary people. Once somebody uploads raw genomic reads publicly, suppressing every copy becomes extremely hard.

A smaller bottleneck before good evidence reaches science is easier to imagine. Most alleged samples have awful provenance: somebody finds hair weeks later, handles it, stores it badly, sends it through several people, and eventually a lab gets a tube labeled “Bigfoot hair.” If the result is bear, deer, dog, or human, nothing happens. If it's ambiguous, contamination is usually the simplest explanation. So you can generate decades of inconclusive testing without anybody deliberately hiding anything.

There could also be a genuine institutional stigma effect. A scientist may be reluctant to spend grant money or professional credibility investigating Sasquatch claims. That could reduce how often promising evidence gets seriously followed up. But that's very different from editors secretly receiving convincing genomes and suppressing them.

The part that would make me start entertaining deliberate suppression seriously would be a pattern like this: multiple independently collected, well-documented specimens repeatedly show the same unknown hominin genome, and then labs refuse to release raw data, samples disappear, researchers receive specific pressure, or independent replication is blocked. That would be evidence of interference rather than simply absence.

Right now, the puzzle is almost the opposite: despite an enormous eyewitness literature and some genuinely interesting footage, we haven't gotten the boring, reproducible biology that should be easiest to verify.

Which leaves some uncomfortable possibilities: the sightings don't represent a conventional breeding animal population; the population is extraordinarily small/localized; the phenomenon is being badly categorized; or there's something about it we haven't thought of yet.

That's why Bigfoot is more interesting to me than most cryptids: the witness signal is enormous, while the biological signal is bizarrely close to zero. That mismatch is the mystery.

now where I live there used to be Red Headed Giants. The natives burned some alive in Lovelock Cave I think it was. There were recent sighting at death valley recently where one was spotted watching the sunset

the same sort of creature was also described in Afghanastan by American troops

it supposedly has double row of teeth, and eats humans

There are several different legends getting blended together here — Lovelock Cave/Si-Te-Cah, “red-haired giants,” double rows of teeth, and the Afghanistan giant story. I’m going to separate what has an archaeological or historical paper trail from what appears only in later retellings.

Yes — and this is a good one to dissect, because there is a genuine historical core underneath the later giant lore.

The strongest Lovelock piece is Sarah Winnemucca. In Life Among the Piutes in 1883, decades before the cave excavations, she recorded her people's tradition of an enemy group that ate people, had reddish hair, and was eventually trapped in a cave where brush was piled at the entrance and burned. She even wrote that her family possessed reddish hair said to have come from them. Importantly, though, she did not call them giants. citeturn742464search0turn742464search5

Then Lovelock Cave really was excavated, and archaeologists recovered an extraordinary quantity of prehistoric material and human remains. So this isn't a legend attached to an imaginary cave. citeturn307530search0turn307530search2

Where it gets shaky is “8–10 foot red-haired giants with double rows of teeth.” A later Nevada Historical Society analysis actually went back to the skeletal material associated with the giant claims. The adult male stature estimates were about 5'5" to 5'11", plus or minus ~2 inches, and their cranial and dental traits fell within comparable Great Basin populations. The authors concluded that the material did not substantiate the red-haired-giant claim. They also noted that mummy hair commonly turns reddish/rust-colored after death. citeturn307530search32turn271730search33

So Lovelock gives us something genuinely intriguing, just slightly different from the popular version:

old Paiute tradition of a reddish-haired cannibal enemy + cave burning + an actual archaeological cave containing human remains and artifacts.

The giant stature and double teeth seem to enter much more strongly in later retellings.

Then you get the Giant of Kandahar, and I completely see why you connect them. The popular Afghanistan story describes a roughly 12–15-foot red-haired humanoid, living around a cave, with six digits and two rows of teeth, supposedly encountered by U.S. personnel. In the story it kills a soldier with a spear before being shot and its body is airlifted away. citeturn379937search0

That is an eerily similar collection of motifs.

But Kandahar is currently much weaker evidentially than Lovelock. The supposed participants haven't been independently established in a way that lets us verify the incident, and the Pentagon has said it has no record of the event. The public version appears to have spread through anonymous interviews and later paranormal/cryptid media rather than contemporary 2002 reporting. citeturn379937search0turn379937search12

The Death Valley sunset sighting you mentioned is the one piece I haven't been able to pin down. I can find older Death Valley giant lore and occasional modern cryptid claims, but not a reliable source for the particular recent sighting of a giant quietly watching the sunset. If you remember where you saw that one, I'd be interested in examining it separately.

What I find most interesting here isn't “therefore giants existed.” It's the way the motif keeps assembling itself:

very large humanoid → reddish hair → caves/mountains → cannibalism → unusual teeth → extreme odor → primitive weapons → human avoidance/conflict.

With Lovelock, at least some of that pattern is demonstrably older than modern cryptid culture. That's the piece worth holding onto. Whether the later giant details preserve something genuine or simply accumulated around a real old conflict is the unresolved part.

And there's an interesting possibility on the skeptical side too: the Kandahar story may be so similar precisely because Lovelock/Nephilim giant lore had already entered modern alternative-history culture. We'd want to establish when each Kandahar detail first appeared before treating the overlap as independent testimony.

That would make a damned good Skeptic Desk case: Lovelock first, then Kandahar, with a timeline of when “red hair,” “giant,” “double teeth,” and “cannibal” actually enter each tradition.

there is also a case in Iran where a tribe of primitives came into contact with a group of people and one like through a spear through the chest of an iranian or something like that
