Tools predate homo sapiens (which emerged about 300 kYA) by millions of years. The first stone industry - Oldowan - is at least two million years old and might be as old as three million. They predate what we call “archaic humans” by a long time.
Even this evidence of woodworking is largely unremarkable. We’ve got phytolith [1] and microwear [2] studies showing unambiguous evidence of woodworking going back at least 1.5 million years. Wood tools just don’t survive very long, so this find is most notable for its preservation.

Well, today I learned something! Thanks for the information, I guess I know which rabbit hole I'm going down today.
Just edited to add two paper citations for the phytoliths and microwear studies. Have fun! It’s a deep rabbit hole largely ignored by popsci publications so there’s lots to explore.
But the article says "our human ancestors" which implies they are not talking about other hominins."
Edit: Okay I just found that Human can also refer to other hominids
from: https://www.merriam-webster.com/dictionary/human
- a bipedal primate mammal (Homo sapiens) : a person
- broadly : hominid
That's wild! Thanks for sharing. I didn't realize these things went so far back. So are you saying these were straight up non-human primates using tools? Or is this all traceable to our lineage?
The first identified tools were 3.3 million years ago, which is before the homo genus emerges. Thus, those were either by Australopithecus afarensis or by a yet unidentified hominid species -- they were still very likely our ancestors (but technically TBD).
Then around 2-2.5 million years ago you get the first homo species in the genus homo such as Homo habilis and they created the Oldowan tool culture.
Both Australopithecus afarensis and Homo habilis are our ancestors -- however they are also the ancestors of other homo lines that diverged from us that we are not descendents of (which are now extinct).
People often forget how widespread and varied the Homo genus was before all our cousin species went extinct (likely in part due to us).[1] Homo erectus colonized the entire old world very effectively 1.5 million years ago!
[1] https://en.wikipedia.org/wiki/Homo#/media/File:The_hominin_f...
Even today there's plenty of non humans (and non-primate) tool use https://en.wikipedia.org/wiki/Tool_use_by_non-humans.
In terms of tools by homonins, there is a roughly ~3million year history of stone tool use by various species, and the main thing preventing that date from being pushed further back is the difficulty in discerning between stones that have been shaped intentionally and those shaped by natural forces.
Our last common ancestor with our closest non-human primates (Pan genus) diverged about 6-8 million years ago, so what constitutes “human” is murky and I don’t think archaeologists give the matter much thought. “Human” means homo sapiens, “archaic human” means a few subspecies like neanderthals up to about 600 kYA, and the rest are just “hominins”.
We have both observational and archaeological evidence of tool use in chimpanzees, macaques, and capuchins so it’s a pretty widespread behavior. I think the archaeological evidence for monkeys only goes back about four thousand years but thats because we havent studied the issue as much in archaeology.
> Tools predate homo sapiens (which emerged about 300 kYA)
I’m going to use a charged word because Jane Goodall used it.
Goodall asserted that humans and chimpanzees (and wolves) are unique among animals in that we have a genocidal tendency [1]. When a group attacks us (or has “land and resources” we want) we don’t just chase them off. We exterminate them. We expend great resources to track them down to ensure they cannot threaten us.
One reading of pre-history is that we had a number of hominids that were fine sharing the world, and humans, who were not. (I’ve seen the uncanny valley hypothesised as a human response to non-human hominids, as well as other humans carrying transmissible disfiguring diseases.)

Army ants do something similar as well.
https://www.scientificamerican.com/article/ants-and-the-art-...
I think this is part of the reason humans are so stupid during any sort of divisions where "sides" emerge. To be able to do commit this genocide, you need a very ugly "switch" in your head that can make your actions justifiable/right. I think this switch is the same, emotional, unthinking one that makes some people so religion about teams sports, phone OS, political alignment, etc.
Related, I think this is also the mechanism for how religion tends to stabilize societies/give them cohesion. Rather than having an eventual positive feedback loop of division, the division is placed between some type of "good" and "evil" rather than your neighbor. The "us vs them" division that switch craves is put on something more metaphysical (and sometimes a net benefit, like defining evil as behavior destructive to societies).
The worst part of reading this thread is I know I won't be able to google image anything interesting related to "non-human hominids" :( Your comment was oddly depressing lol. Real "are we the baddies?" moment this morning.
Given enough time of human survival, the only species left on this planet will be ones that are aesthetically pleasing to us
Everything selectively bred due to environmental or artificial pressures to have big eyes, big heads, high vocal sounds, attributes of human babies
It is very strange and an aberration amongst species, one being tolerating other beings because of their entertainment value and the joy they give from looking at them, but seems to be consistent and validate what's happened over eons of homo sapien propagation
> (and wolves)
And lions. And banded mongooses. And meerkats. And ants. Lots and lots of ant species - they’re actually by far the worst, following colony pheromones to the end of the earth just to get a single ant. Ants that aren’t genocidal to their own species tend to be some of the worst invasive species (like Argentinian ant supercolonies).
I love me some Jane Goodall as much as the next guy but that hypothesis is not taken seriously by primatologists and using the word “genocidal” in this context would get you laughed out of the room. Lethal intergroup aggression, coalitionary killing, and raiding are all different aspects of violent behavior in animals and hominins are far from unique in demonstrating them.
It’s an interesting interpretation, but it’s sounds all very unsubstantiated. Speculation it seems to me.
Sometimes when I think about this it makes me wonder if we should take the dark forest hypothesis seriously (re: Fermi paradox).
Not only are we the only species to reach this kind of technology but among humans the first group to reach space was the Nazis. Today the innovation in that area seems driven by militaristic states and by people who seem ideologically adjacent. In other words it’s driven by very aggressive territorial members of one of the most aggressive territorial species.
We can’t generalize from one example of evolution, but if this is indicative of a common pattern then there might be some scary MFs out there. Our radio signals have been spreading for a while, so for all we know something is on its way to cleanse the universe of all forms of life that offend its god (or whatever its genocidal rationalizations is).
If this is true then we die. There is zero chance of resisting something with the technology to travel the stars and perhaps a million years or more head start on us. It’d be like an Apache attack helicopter versus a termite mound.
I had this thought when I saw the ideological turn (or mask removal) of certain people in the space industry. I found it metaphysically disturbing. Again… if there is other advanced life and if this is the pattern of how you evolve to become spacefaring, then we are doomed.
> unique among animals in that we have a genocidal tendency
That's an unsupported generalization.
The article describes "behaviors" that include "perhaps even genocide", and notes that wiping out populations exists in chimps and wolves too.
So not unique, there's a "perhaps", and it's not a tendency. There's no evidence we have a "gene" for it or anything.
In the vast, vast, vast majority of conflicts between two groups, we don't exterminate the "enemy". Otherwise, the human race would have gone extinct a long time ago. Wiping out entire populations is by far the exception, not the rule, of human societies. It happens, but the situations are notable precisely for their extremity, precisely because they're not the norm.
The submission's subheading seems to imply that there was a gap where homo* emerged but weren't using tools then though? I can't read the article or copy-paste it due to pay wall, but it says something along the lines of the find suggesting our human ancestors were using tools longer ago than we thought.
Way back when I was in high school doing history (Money for Nothing was on heavy rotation on the radio and Bob from Stranger Things was still Mikey from the Goonies), our teacher explained that there was evidence of stone tools being used by early hominids, then nothing much except maybe fragments of rock that may have been used as hammers or axe heads, and then into an era where simple bronze tools emerged. What archeologists believed, she said, was that people went from "big chunk of rock" to "small delicate bit of rock tied with strips of animal hide to a stick" to "big chunk of metal", and the wood and animal hide had simply rotted away. There would be this whole lost chunk of technology.
And she told us that would likely happen again, there would be a gap where our technology proved to be insufficiently durable to last throughout history. Unsurprisingly not everyone in the class thought this was likely, but I figured it was possible.
Anyway, I could go on about the archeology of tech all night, but I've got to figure out how to get the photos off this Kodak DC25 camera card. Something about a DLL from the original installer that you wrap in a Linux library? Can't remember.

> Even this evidence of woodworking is largely unremarkable .... this find is most notable for its preservation.
This somewhat contradicts the subheading, no?
> The finding, along with the discovery of a 500,000-year-old hammer made of bone, indicates that our human ancestors were making tools even earlier than archaeologists thought.
That subheading is complete nonsense and I can't think of a single charitable reading of that sentence that in any way makes sense. Archaeologists have known that our ancestors have been making tools for over a million years since the Acheulean industry was conclusively dated in the 1850s. It took half a century for archaeologists to figure that out after William Smith invented stratigraphy. Scientists didn't even know what an isotope was yet.
The original paper's abstract is much more specific (ignore the Significance section, which is more editorializing):
> Here, we present the earliest handheld wooden tools, identified from secure contexts at the site of Marathousa 1, Greece, dated to ca. 430 ka (MIS12). [1]
Which is true. Before this the oldest handheld wooden tool with a secure context [2] was a thrusting spear from Germany dated ~400kYA [3]. The oldest evidence of woodworking is at least 1.5 million years old but we just don't have any surviving wooden tools from that period.
[1] https://www.pnas.org/doi/10.1073/pnas.2515479123
[2] This is a very important term of art in archaeology. It means that the artefact was excavated by a qualified team of archaeologists that painstakingly recorded every little detail of the excavation so that the dating can be validated using several different methods (carbon dating only works up to about 60k years)

As others mentioned, tool use wasn't restricted to homo sapiens. I think this makes sense, no? We didn't spontaneously use tools, it must have evolved incrementally in some way.
I think we see shades of this today. Bearded Capuchin monkeys chain a complex series of tasks and use tools to break nuts. From a brief documentary clip I saw [0], they first take the nut and strip away the outer layer of skin, leave it dry out in the sun for a week, then find a large soft-ish rock as the anvil with a heavier smaller rock to break open the nut. So they had to not only figure out that nuts need to be pre-shelled and dried, but that they needed a softer rock for the anvil and harder rock for the hammer. They also need at least some type of bipedal ability to carry the rock in the first place and use it as a hammer.
Apparently some white-faced Capuchins have figured out that they can soak nuts in water to soften it before hammering it open [1].
You might be old enough to have been taught that Humans are tool-using apes. That's tragically incomplete: lots of apes use tools. Birds use tools. And now, cows use tools!
I was homeschooled in a particular conservative area. Much of what I have been taught was... woefully inadequate, we'll say. Lots of my learning has come in university and afterwards, so what I've picked up is pretty obviously incomplete and leaves me with many unknown unknowns in this area. Today has begun filling in many of those gaps so they get to be known unknowns now!
> Lots of my learning has come in university and afterwards
That's true for pretty much everybody. Homeschooled or not. You think everyone shocked by this news was all homeschooled?
https://en.wikipedia.org/wiki/Veronika_(cow) might be a better Wikipedia link.
Honestly I would have expected a pig or horse to be discovered to use tools, rather than a cow. Cattle are generally... not thought of as particularly intelligent.
That's the goal of https://www.cowbrushes.com/store ! They provide mental stimulation and scritches for cows. Results in extra milk, too.
Yes it's definitely further back than homo sapiens have existed (200k - 300k years), but our ancestor species were known to have used tools and control fire. I believe we have evidence of tool use going back 1 million years. So this article is referencing the oldest known _wooden_ tools, which are obviously much less likely to be preserved across the ages.
We have 3.3 million year old stone tools https://www.nature.com/articles/nature14464. They're very simple (even more so than the Oldowan stone tools https://en.wikipedia.org/wiki/Oldowan) and basically just look like rocks, but there is clear evidence of intentional shaping by hominins (somewhere in the fuzzy late Australopthis/early homo transition).
We have evidence of control over fire (but not fire starting) at about 1 million years. Stone tools go even further back, at least 2 million years.
Wait hang on, would they "control" file by finding natural sources (volcano, lightning strike wildfire, etc.) and then make use of that source for controlled sources of light/heat/etc? I guess I've always thought of "control" of fire including the intentional starting thereof.
There's a 476k year old wooden structure in Zambia, and includes some tools somewhere around 3x0k years old: https://en.wikipedia.org/wiki/Kalambo_structure
Fascinating stuff!
This isn't a problem for evolutionary theory. It's literally a necessary prediction of it. Most recent common ancestor of humans and chimps is 5-10 million years ago. Since we have observed tool usage in modern chimps and lots of very complicated tool use in humans, the necessary prediction is that some amount of tool use goes back at least ~5-10 million years, with increased complexity roughly tracking with the continuous increase in braincase size.
Being in a common ancestor is certainly compatible with evolution but it's not necessary because it could have evolved independently in each branch.
if it were only 2 primates that's a plausible explanation, but when it's pretty much every simean using tools, and all the old world apes making tools, it's pretty hard to argue for convergent evolution rather than a trait that exists ancestrally.
I don't understand why you think it'd be an issue?
Dumbed down understanding of mine: evolutionary theory predicts that graph goes from (0.1; 0) to (very high; in a million years). X axis: years, Y axis: progress or evolution. The only difference such discoveries make is to further refine the slope of the graph. Was the development linear or exponential? How fast did it progress? Obviously, in the past 500 years we didn't change as humans but our technological progress accelerated beyond belief.
Then ... you find out that smoking was introduced to the new world in the 16th c, and indigenous North Americans didn't start using the bow & arrow ubiquitously until after the year 1000. But! Native North Americans were using copper contemporaneously with the old world.
What if the meaning / definition of ETA when used like this?
It might be just my perception, but it seems like every single time anthropologist make statements to the effect that complex human development didn't start until XX they are proven wrong. It wouldn't bother me so much if it wasn't for the fact that those "estimates" are generally used as proof to dismiss alternative timelines for human progression. I'm certainly not trying to say the planet had Atlantis with flying cars 300,000 years ago; but it certainly seems plausible that there were large/complex societies beginning long before the advent of our current written history... an idea that is regularly dismissed as foolish.
There's bound to be a lot of vital archeological evidence of the development of humans and our cousins below the water. Past peoples probably lived near the coasts and the rising water would have obscured or destroyed a lot of the evidence of their existence. I think a lot about what must be or have been just out of reach of our current studies.
That’s rapidly changing. Underwater archaeology has been going through a mini-Renaissance in the last thirty years thanks to multibeam and side scan sonar. Now with the proliferation of underwater drones capable of high-resolution 3D photogrammetry, that is rapidly accelerating into a full blown revolution. As usual the problem is lack of funding to do excavations. There are far more known sites than there are funds to study them.
Ancient crops were also pathetic to a modern eye. Before thousands of years of selective breeding, corn had six or seven kernels on a cob. Doubtful that it would be possible to survive on a field of wild cultivars without at least a few generations pushing towards more productive specimens.

Article title is click bait.
Hominin tools that are millions of years old have already been found by archeologists.
e.g., recent news: Scientists uncover 3-million-year-old tools but they weren’t made by our ancestors: https://www.futura-sciences.com/en/scientists-uncover-3-mill...
A list of findings of earliest known hominin tools: https://en.wikipedia.org/wiki/List_of_earliest_tools
Without assuming correctness, assuming instead "risk probability" - if previous advanced civilizations have risen and fallen on Earth, after evolving here naturally - what should we do as a species to not share their fate?
edit: I am not sure backupping to 'Mars', with its lack of magnetic field, inhospitality, and necessity to live underground is a positive idea
> The finding, along with the discovery of a 500,000-year-old hammer made of bone, indicates that our human ancestors were making tools even earlier than archaeologists *thought*.
I am tired of this. No. Archeologist only claim what they have discovered. They don't speculate because they work based on evidences. Journalists should better. This wording sounds like archeologists were wrong. That only fuel the narrative that layman's opinion is more informed than professionals.
True but every science headline is misleading, loaded or exaggerated. My pet peeve "X found where it should not exist". What they mean is "scientists are pleased because there's some new evidence that is not explained by their current models and that means they get to improve their models which is the goal of science anyway, so pretty much just another day for science but glad to keep you updated"
I'm not so sure if that's too wrong.
Science works by scientist having a model of reality and then testing that model against reality, gathering evidence that fits or doesn't fit the model, evaluating how well the model corresponds to reality.
If there is a widely accepted model in the archaeological community, and the new data contradicts it, the wording "than archaeologists thought" seems plausible enough.
Of course, depending on the model, the model itself might admit regimes of "non-applicability", or have some measure of confidence... If archeologists have large uncertainty whether human ancestors made tools 500,000 years back or not, then they shouldn't be surprised upon finding evidence that the ancestors did.
I don't know any specifics about this case, just arguing that that kind of wording by itself is not always wrong by default.
I have always believed that the human evolution consensus which is usually based upon finds of advanced toolmaking in absence of culture cues, to be questionable by orders of magnitude. So it seemed natural to simply double generational concepts of the village along a trade route, from ~500kya (like the Nile) to 1 million YA as a hyperstable span of evolution of the 'trade route village'. I even wrote a book about it https://www.youtube.com/watch?v=mtxgpaXp9vA that might seem like whole fiction. But science seems not to ask, how many times might we have started over?
That's ridiculous. Scientists absolutely ask these questions. We just don't have the answers so we don't make assumptions. It is implicitly assumed there is an enormous amount of proto- and pre-human culture and technology that is undiscovered or undiscoverable. We have very long known that hominins made tools, art and structures out of organic material that has decayed beyond our ability to detect.
That's how these evolutionary scientists do read it - 'the race to find the evidence to backup our concepts of intelligent hominid behavior has achieved another breakthrough'. The journalists frame it as 'scientists are shocked again' to get more views/engagement. No doubt some 'scientists', being people, probably get taken in by the journalists framing too.
What's incredible about this too is they found it in England, which means they had to first build a boat to get there and leave the tools on the island
England wasn’t always an island
Estimates will continue to go earlier, and more things that were, or are, alive will be considered exceptional. Seems to be a function of looking.
Ok, since I moved to the US from Europe a few years ago my perception of wood has changed a lot, especially for construction. Seeing this reinforces my view.
Wood lasts for fucking ever under the proper conditions. Old construction in Europe often only had the beams made of wood, and I always thought that was orders of magnitude more durable than wooden houses, like thousands of years vs decades. I don’t think that’s true anymore.
And this might be one of the few environmentally friendly decisions that Americans got better than Europeans, I guess. Wood is still prevalent in construction here, and as far as I know concrete and cement production are quite bad.
BTW, I’m a total ignorant about all this so just intuition and probably wrong
It's not totally a "decision" on the part of the Americans to use a lot of wood in construction. It's just that America has tons of space, including space useful for growing Douglas Fir and Southern Yellow Pine, which then can be turned in to 2x4s and other construction lumber.
Most of Europe long ago exhausted easily accessible natural forest resources, and where it's not densely populated tends to prefer using land to do other stuff (like grow food). Hence, stone and concrete and similar materials in European construction.
While some lumber production happens in the United States, most lumber is imported from Canada. That's because while the USA does have good tracts of land on which lumber is grown, Canada has much, much more. This is why you see "Made in Canada" stamped on quite a lot of plywood and plenty of timer used in residential construction.
The part that I don't quite know how to make sense of is why Canadian producers seem to have a near monopoly on sandpaper products.
The US imports about 30% of its lumber. Canada is the largest source of imported lumber, but it's still less than a quarter of all lumber consumed in the US. Surprisingly, the limit on US production is not trees but sawmill capacity.
Sandpaper requires specific grades of corundum; Ontario happens to have several notable large deposits of extremely fit-for-purpose corundum. The Canadian deposits were also a conveniently close source for what would become America's largest abrasives products producer, 3M, after its attempt to mine corundum in Minnesota failed (3M stands for Minnesota Mining and Manufacturing company).
>concrete and cement production are quite bad.
Modern concrete construction uses iron rebar liberally. That means every concrete structure built today will crack and crumble in a few hundred years at most, as the iron absorbs oxygen, it swells from the rust. Which is a shame, roman concrete buildings without rebar will still be standing 1000s of years from now.
Roman construction was also much less efficient because they had no material (besides wood) capable of carrying load in tension. Rebar allows us to make cheap practical structures that are impossible with just concrete - roman style or not.
It would be quite fascinating to see what kind of structure we could produce if we decided to make the longest lasting cement structures we could create with modern technology, and assuming minimal maintenance over the lifetime of the building. A one-and-done kind of structure.
I bet we could do fairly well. Hundreds, maybe even thousands of years. We've learned a lot about how to form exceptionally long lasting cement. We just choose not to do it that way, most of the time.
Petrified wood is stone. The stone matrix has formed around a wood structure, but the properties which remain are those of stone, not wood.
Wood is a composite material, strong under both compression and tension. It's the fibres in wood (lignans) which provide the latter. Stone (and unreinforced concrete) lack such fibre elements, and are strong only under compression.
With stone it's necessary to build compression structures such as arches and domes for heavy load-bearing, and taller structures must be significantly flared out at the base (or utilise buttresses, as with gothic cathedrals) for stability. Structures under tension can be far more lightweight and compact.
Steel-box construction and reinforced concrete both offer tension-based strength, but are also susceptible to metallic oxidation (rust), which limits the life of such structures. A nonmetallic fibre (natural or synthetic) might offer an alternative to this, and I've seen some work investigating this, though there may be other issues (e.g., depolymerisation of plastics over long periods of time).
There are wooden framed houses built in the UK now, particularly in Scotland. The problem with a lot of American houses is the piss poor insulation which leads to energy usage 2-3x that of equivalent European houses. Maybe that's changing now.
A big problem with houses is we never rebuild. It's kind of crazy. We replace almost everything else eventually, including commercial buildings. Skyscrapers only last a few decades. But we expect houses to last forever. But they're only getting older. Is it possible to strip a wood building right back to the frame and start again?
There's no intrinsic reason balloon-framed housing has to be poorly insulated, and properly-insulated (and wrapped) balloon-framed construction is actually far better insulated than the "well-insulated" thick-walled structures based on stone, packed earth, brick, etc., which traditional half-timbered or masonry structures offer.
There is of course a large stock of extant housing which pre-dates best-standards insulation practices, though much of this can be improved dramatically at relatively low cost, especially by improving siding ("wrapping") and insulating attics. Thicker walls (nominal 2x6 rather than 2x4, or greater) can also be retrofit, either extending the exterior or interior wall dimension, though at considerably greater cost, and with trade-offs to either exterior or interior dimensions (lot size, environment, or reduced interior volume).
I wonder how would we react with tools dating back to, say, 5MY ago ...
That would shake our knowledge from the foundations.
No it wouldn't, as we already think it's pretty likely. Chimpanzees use tools, so our most recent common ancestor with them, something like 6 million years ago, may well have used tools too. https://en.wikipedia.org/wiki/Tool_use_by_non-humans, https://en.wikipedia.org/wiki/Chimpanzee%E2%80%93human_last_...
I don't think so, have you read 'The Bonobo and the atheist'? Humans are not the only ones using tools and in reality there isn't much difference between humans and animals. The conclusion I get from the book is that the only difference is religion. Although, I have a feeling that humans do have a more developed intellect (problem solving) but this was not explored in the book.
Do we know if these were formed intentionally or just happened to be in such a form and were used by those that found them?
Do we know if these were used more than once, or if they were in a convenient shape that was grabbed by a local for one time use?
How do we know that these were actually used as tools and not just pieces of wood that coincidentally in the site?
Do we have any reason to think these were used by (precursor to) humans more than ravens, beavers or any other number of animals that use tools?
Because of the paywall I could not read the whole article, but the pictures and intro leave a lot unanswered.
Website has problems, NYT version: https://www.nytimes.com/2026/01/26/science/archaeology-neand...
Thanks, we've switched to that from https://archaeologymag.com/2026/01/430000-year-old-wooden-to... and put a couple extra links in the toptext.
Yeah, that was me. I threw the link into archive.is to check if it had a snapshot, but it just created a shanpshot of the 503 before I could figure out how to cancel it.
There is archaeological evidence of tools going back even further, potentially over a million years, but it's ignored for the usual reasons of dogma and not conveniently fitting into the paradigm of the current priestly class. I'd highly recommend this talk Michael Cremo (author of "Forbidden Archaeology") gave for this "Authors at Google" program in 2014:
> There is archaeological evidence of tools going back even further, potentially over a million years, but it's ignored for the usual reasons of dogma and not conveniently fitting into the paradigm of the current priestly class.
? I don't think you can find anyone in archaeology who says tool use began less than 1 million years ago (mya). Maybe you mean something else?
The univeral consensus in archaeology says tools emerged either 3.3 mya, which is still subject to debate last I knew, and certainly by 2.58 mya - the Odowan industry famously discovered by the Leakeys in the Oldovai Gorge in Tanzania, in 1969.
The same consensus continues with the development of the more advanced Acheulean industry ~1.76 mya, which dominated until ~ 400,000 years ago (arguably the most successful technology ever).
That book name is... off putting, and his wikipedia article (https://en.wikipedia.org/wiki/Michael_Cremo) isn't encouraging in a quick scan...
It instantly destroys all credibility. Any serious theory would present itself on its own merits rather than going for the victimhood angle. When you title your book in such a way as to push the perceived victimhood to the forefront, it indicates that there is no convincing evidence and therefore the only option left to you is to play at the conspiracy angle, cursing the shadowy figures who are suppressing the "forbidden truth".
Why not just watch the talk and hear his argument from himself?
Wikipedia has a bias against everything outside of mainstream academia, there are activist groups like Guerrilla Skeptics that go through articles and rewrite them to undermine anything remotely fringe. It's not as objective as people like to think it is.
Because life is short and we have to prioritize the talks we watch. And if you've seen enough bullshit, you can smell it coming. So if someone gives strong signals that they're full of it, we don't bother.
Because charismatic people can make us believe just about anything, and if we think we're immune to that we just haven't met the right charismatic person. I like to do some searching when something jumps out at me, like his book name, to get some background before I invest more time into the topic.
I'm not the person you asked this of, but I've worked in museums and research settings and can lob a response your way.
Ultimately, it's that scientists are humans, too. Despite some of them really making their research data-forward, things like tenure, career, funding, and even who would publish your work now and in the future all create normal human environments that reward small, incremental changes to a body of knowledge that don't upset the apple cart, not discoveries that suggest huge changes. In fact, large changes and discoveries can be resisted and denied further research in favor of the status quo.
This is not a new phenomenon by any means:
Both warm-blooded dinosaurs and the Chicxulub impact were both theories dismissed as fringe for decades before overwhelming evidence led to them being accepted as likely. In no small way thanks to Jurassic Park.
Recall that eugenics and phrenology both used to be widely accepted scientific "fact."
100 fairly prominent scientists signed a letter stating emphatically that Einstein's Theory of Relatively was categorically wrong and should be retracted.
Plate tectonics was seen as fanciful crackpot musings for decades. The author of the original theory died 30 years before plate tectonics was even considered possible.
Germ theory was dismissed for most of Louis Pasteur's lifetime, despite being able to literally show people yeast in a microscope.
Helicentrism has a storied past.
Quantum theory was also denied heavily at first. Now it saves photos to our hard drives.
And how many times has the earliest dates of hominids and tool use and human thresholds of development been pushed back by tens of thousands of years?
This is not an exhaustive list, by any means.
So we have ancient examples and modern ones - and everything in between. So the level of education or scientific progress or equipment are not the cause. Humans are. Humans do this all the time. So until overwhelming evidence surfaces, which can take decades or longer, claims like this shouldn't be dismissed out of hand until proven solidly in error. A theory is a theory, so let it be a theory.
> Both warm-blooded dinosaurs and the Chicxulub impact were both theories dismissed as fringe for decades before overwhelming evidence led to them being accepted as likely. In no small way thanks to Jurassic Park.
The main rejection of the impact hypothesis was that the dinosaurs had already died off by the time of the impact, the idea that the iridium in the layer came from an impact was reasonably well received. In 1984 a survey found 62% of paleontologists accepted the impact occurred, but only 24% believed it caused the extinction. The Alvarez duo, who proposed the impact hypothesis, were proposing to redefine where the cretaceous ended based on a new dating method (at the time the end of the cretaceous was believed to be a layer of coal a few meters off from the now accepted boundary), and fossil evidence at the time seemed to show gradual decline. A big part of the acceptance of the theory was the development of new analysis methods that showed the evidence for a gradual extinction prior to the impact to be illusory. By the time the impact crater was identified, it was already the dominant theory. Actually in the early 90s major journals were accused of being unfairly biased in favor of the impact hypothesis, with many more papers published in favor than against.
Completely coincidentally, the theory that the chixulub structure was an impact crater was initially rejected and it wasn't until 1990 that cores sampled from the site proved it was.
Dinosaurs being warm blooded was well accepted by the late 70s.
> I've worked in museums and research settings
You've worked in those settings, and you think archaeologists reject tool use older than 1 mya?
Also, you don't understand that science is a process, based on evidence, and revision is an essential part of that process? Archaeology especially advances regularly, because evidence can be relatively very rare. If they weren't revising it, it would mean the whole research enterprise - to expand knowledge - was failing.
> how many times has the earliest dates of hominids and tool use and human thresholds of development been pushed back by tens of thousands of years?
I don't know, how many times? Tool use is universally believed, in the field, to have begun at least 2.58 million years ago, and with strong evidence for 3.3 mya. Tens of thousands of years isn't in the debate. See this subthread:
>Also, you don't understand that science is a process, based on evidence, and revision is an essential part of that process?
I do, and the process is exactly the point. That human emotions affect the process far more often than we like to admit. Not always, but it's not completely removed from the process by any means.
In each of those cases, it's that no one says, "Oh, new theory, new evidence. Cool, let's test the hell out of it!"
People in positions of relative power sometimes say, "New theory? Nope. Not even going to look at it. No, in fact, you're crazy and you're wrong and get outta here!"
In each of those examples, to some degree the eventual more accurate theory met emotional resistance by people adhering to the status quo, not resistance because of questionable data or poor research methods or non-reproducibility.

I like how the word “overwhelming” is doing a lot of heavy lifting here.

I mean that's how science works. Things can be dismissed until they're proven true. If there's a valid path to finding out it's true then you can try to get funding, it just takes work and convincing people as you're competing for sparse resources. And getting egg on your face is also part of the process.
It took about 30 years for every geologist to reach consensus on tectonic plates and continental drift. Old heads who'd invested a lot of their credibility arguing against it had a lot to lose by admitting they were wrong, so they refused to do it.
Bill Bryson's book A Short History of Nearly Everything is where I'm taking that from. It's a great read and shows all the ways in which scientists failed to see what was under their nose for decades before finally figuring out, which makes one wonder what's currently ripe for the picking.
I think it just doesn't fit into the accepted timeline so it's mostly ignored. This is a common pattern with scientific discovery where evidence that contradicts the prevailing paradigm is ignored and builds up until it can no longer be ignored and causes a paradigm shift. This idea comes from The Structure of Scientific Revolutions by Thomas Kuhn.

Please edit out swipes, as the site guidelines ask (https://news.ycombinator.com/newsguidelines.html), regardless of how wrong someone is or you feel they are.
Your comment would be fine without that first bit.
430,000 years? Am I reading this headline correctly? (since the site seems to have fallen victim to the HN-hug-of-death). That seems wildly further back than I understood humans to have tools, or even homo sapiens to have existed.
ETA: Today I learned I had a much much larger gap in knowledge than I thought I did. Thanks to everyone for the information and links!
