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

Yeah — a live 5–6 inch quaking aspen is not a trivial thing to snap, even though aspen is relatively weak wood.

USDA data puts the modulus of rupture for green quaking aspen around 5,100–5,500 psi. citeturn970744search30turn970744search31

If you model a 5–6 inch trunk very crudely as a solid circular beam, you get a breaking moment on the order of roughly:

• 5 in: ~5,200 ft-lb
• 5.5 in: ~6,900 ft-lb
• 6 in: ~9,000 ft-lb

That’s not a precise real-tree number — knots, rot, grain, leverage, prior damage, and dynamic loading can change it enormously — but it gives you the scale.

If something were applying force about 5 feet above the break, the rough lateral force needed would still be on the order of 1,000–1,800 pounds-force for sound green wood.

So if the video genuinely shows:

a healthy 5–6 inch living aspen → intact beforehand → creature seated → snaps it at the trunk without hidden leverage → then launches the broken section ~50 feet

...then the strength display is much more interesting than just “a guy in a suit walking around.”

The problem, as always, is provenance. I found one widely circulated clip called the Highcliff video where a seated dark figure appears to tear at a tree and later stands up, but that particular clip has a messy history and allegations that it was connected to TV production. citeturn243491view0

So I’m not sure that's the exact one you're talking about.

But purely on biomechanics: yes, 5–6 inches of live quaking aspen changes the conversation substantially. That isn’t something an average human casually snaps while sitting down.

yeah like 30ft of tree it just lobs like 50 ft

Yeah — if it really was roughly 30 feet of fresh aspen, that could easily be on the order of 100+ pounds even with tapering.

USDA material puts green aspen around 40–45 lb/ft³. citeturn244784search26turn244784search27 A rough 30-foot tapered trunk section starting around 5–6 inches thick works out to roughly 100–120 lb, depending on taper and moisture.

So the sequence you’re describing is not merely:

“something broke a small tree.”

It’s more like:

while seated, it breaks a live 5–6 inch aspen trunk, handles a ~100-pound awkward 30-foot pole, and then throws it tens of feet.

If the video has good scale, continuity, and no indication the tree was pre-cut or rotten, that is an extremely impressive strength demonstration. An ordinary person in a costume would have a very hard time reproducing the whole action naturally.

And yet—back to our original problem—even a spectacular video like that still leaves us staring at the same maddening question:

Where is the hair, scat, bone, blood, tissue, or body?

That’s what makes Bigfoot so damn peculiar. The best behavioral evidence can look genuinely difficult to explain, while the biological evidence remains almost nonexistent.

some people say it is some other creature in a ghille suit, a lot of sightings are accompanied by lights in the sky

but many encounters included throwing rocks, not to hit the person, but close enough to warn

lots of times it happens after humans pee near a camp

Yeah, and the rock-throwing part is one of the more interesting recurring motifs because it maps onto real primate threat behavior surprisingly well.

BFRO has multiple reports where rocks are thrown near people, into water beside them, onto cabins, or into camps in ways witnesses interpret as “leave” rather than “attack.” For example, one British Columbia case describes large rocks being hurled into the creek mouth beside a family’s camp until they retreated to their boat; another Washington report describes repeated rock throwing accompanying aggressive vocalizations. citeturn671669search3turn671669search1

And known primates really do use objects in threat displays. Chimpanzee displays can include throwing rocks or loose material, dragging branches, stomping, and hitting trees; macaques and capuchins have also been documented throwing stones in social or agonistic contexts. citeturn798718search4turn798718search5turn798718search9

So if you strip away the Bigfoot label, “large primate throws objects nearby as a warning without trying to injure you” is biologically plausible behavior.

The urination trigger is harder. I found reports involving alleged Sasquatch urine and territorial/scent-marking interpretations, including one Alberta campsite case, but I did not find strong evidence establishing a consistent pattern that humans urinating near camp causes the encounter. That sounds like something that may recur in anecdotal lore, but I wouldn’t call it demonstrated from the material I found. citeturn798718search1

The lights-in-the-sky / UFO connection is where the hypothesis changes categories entirely. If those reports are real and causally connected, then the “undiscovered North American ape” model becomes much less satisfying, because now you’re trying to explain a terrestrial primate plus aerial anomalies. But the coincidence problem is severe: people camping remotely at night are also exactly the people most likely to notice satellites, aircraft, meteors, Starlink, military activity, etc.

So I’d keep two hypotheses separate:

Biological Bigfoot: the rock throwing, bluffing, vocalizations, odor, territorial behavior, and avoidance of direct confrontation actually fit a hypothetical large intelligent primate reasonably well.

“Something in a suit / transmedium / UFO-associated” Bigfoot: potentially explains the bizarre absence of bodies and biological material, but requires much stronger evidence because it adds an entirely new phenomenon.

The first one explains the behavior better. The second one tries to explain the missing biology better.

And that tension is exactly why Bigfoot stays interesting.

it also has considerable history, it didn't just pop up with that film in the 60's, native americans have legends, mountain men told stories about them in the 1800s, and the phenomenon occurs around the glove

it also has considerable history, it didn't just pop up with that film in the 60's, native americans have legends, mountain men told stories about them in the 1800s, and the phenomenon occurs around the globe

Exactly. That’s one reason I don’t think “Patterson filmed a guy in a suit in 1967 and everybody copied it” is an adequate explanation of the whole phenomenon. The 1967 film may have standardized the modern image of Bigfoot, but the underlying “large hairy humanlike thing in the wilderness” tradition is much older.

In the Pacific Northwest, the word Sasquatch itself comes from Sasq’ets in the Halq’emeylem language of First Nations people in southwestern British Columbia. Indigenous traditions involving large, humanlike forest beings existed before the modern Bigfoot craze, although they’re diverse—some describe physical beings, others spiritual or dangerous beings—so it’s misleading to collapse every Native story into the modern zoological Bigfoot. citeturn525243search1turn724305news39

There are also pre-20th-century European-American accounts. Explorer David Thompson recorded enormous tracks in the Canadian Rockies in 1811, measuring about 14 by 8 inches, although interpreting those tracks as Sasquatch is retrospective rather than something Thompson himself established. Throughout the 1800s, newspapers repeatedly carried “wild man” stories; an 1886 Maine report, for example, described a supposedly ten-foot-tall hairy wild man. Some of those old newspaper stories were undoubtedly hoaxes or folklore, but the motif clearly predates Patterson by many decades. citeturn724305search9turn724305search11

And by 1924 you already have Ape Canyon: miners near Mount St. Helens reported being harassed by large, hairy, ape-like creatures, including rocks being thrown at their cabin. That's more than forty years before Patterson-Gimlin. Contemporary newspapers reported it at the time. citeturn724305search1

Then the name “Bigfoot” doesn't even arrive until 1958, after giant footprints were publicized in northern California. So the chronology is roughly:

Indigenous traditions → frontier “wild men” → early-20th-century ape-men/Sasquatch reports → “Bigfoot” name in 1958 → Patterson-Gimlin in 1967. citeturn724305news38

And you're also right about the global wild-man phenomenon. Himalayan traditions have the Yeti; Australia has the Yowie; China has the Yeren; Central Asian/Caucasus traditions have the Almasty/Almas; Sumatra has the Orang Pendek. They aren't identical traditions, and lumping them into one biological species would be a huge leap, but the general idea of a hairy, humanlike being living beyond settled civilization appears in widely separated cultures. Smithsonian explicitly notes the parallel between Sasquatch and Himalayan Yeti traditions. citeturn525243search3

And that makes the problem more interesting.

Because now we have two competing observations:

Historical depth: people weren't all reacting to a 1960s movie. Some versions of this motif are much older and geographically independent.

Physical absence: despite that enormous span of time and geography, we still don't have the damn body.

That actually pushes me away from simple explanations at both ends. “Obviously an undiscovered ape” doesn't deal adequately with the missing biology. But “everybody started imagining Bigfoot after Patterson” doesn't deal adequately with the history either.

The global recurrence could still arise because humans everywhere independently generate a wild-human archetype—the dangerous, hairy person living outside civilization. Bears, other animals, hermits, folklore and perceptual mistakes could then continually reinforce it.

But if you could identify a set of very specific behaviors that recur independently before modern Bigfoot media—rock throwing without hitting, foul odor, avoidance of humans, family groups, vocalizations, tree manipulation, etc.—then we would have something considerably more interesting than merely “lots of cultures have hairy monsters.”

That's where I'd dig next. Not whether every culture has a Bigfoot, but whether the behavioral fingerprint existed independently before the modern story could contaminate it.

maybe it is close enough to human that we can't recognize the dna as being not human?

Not really — if the DNA sample were good enough, we would probably recognize that it was not ordinary modern human DNA, even if the creature were a very close relative.

We can already distinguish modern humans, Neanderthals, and Denisovans genetically, even from ancient and degraded material. Researchers can identify lineage-specific DNA fragments from sediments and distinguish those hominin groups at diagnostic sites. citeturn650312search0turn650312search1

And Denisovans are a good reality check here: they were close enough to us to interbreed with humans, yet their genome was still identifiable as belonging to a distinct archaic hominin population. citeturn650312search1turn650312search4

So if Bigfoot were something like a surviving sister lineage to Homo sapiens — say, a population that split from us a few hundred thousand years ago — a decent whole-genome sample should look something like:

“Whoa. This is hominin DNA, very close to human, but it sits outside normal human variation.”

That would be spectacularly obvious to a population geneticist.

Where your idea could matter is with lousy evidence.

A lot of alleged Bigfoot material is probably tested using: - short mitochondrial fragments - PCR assays designed for known species - contaminated hairs - samples containing human handling DNA - degraded environmental DNA

If a truly unknown hominin were extremely close to humans, a crude test could potentially come back as “human,” particularly if researchers only sequenced a short conserved region or if actual human contamination dominated the sample. That’s not crazy.

But with high-quality nuclear DNA, that excuse disappears pretty quickly. We can detect differences between ancient human populations, identify Neanderthal/Denisovan ancestry inside modern genomes, and even infer genetic contributions from extinct “ghost” hominin populations for which we don’t yet have a reference genome. citeturn650312search3

So there is actually a really interesting Bigfoot question buried in what you just suggested:

Have any alleged Bigfoot samples repeatedly returned “human” DNA under circumstances where human contamination shouldn't have been present?

Because that would be worth revisiting with modern whole-genome sequencing.

If somebody found an apparently nonhuman hair with intact follicles, documented the chain of custody, sequenced the entire nuclear genome, and got:

Homo — but substantially outside known Homo sapiens diversity

...Bigfoot research would change overnight.

So I wouldn't say “we can't recognize its DNA because it's too human.”

I'd say:

“Weak tests could potentially misclassify a very close hominin as human; modern high-quality genome sequencing almost certainly would not.”

And intriguingly, if Bigfoot really is very human-like biologically, “human DNA” results might deserve more scrutiny than cryptozoologists usually give them.
