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!

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.

throwup238 an hour ago | parent [-]

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.

[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)

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.

> 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.)

> 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.

We are far more subtle and targeted about it as a whole, possibly due to our social structures.

As vapid as the movie (intentionally) is, "Mean Girls" does a really good break-down of things, and perhaps the main issue is that unlike some other animal groups, people don't always stop.

crazygringo an hour ago | parent [-]

No. We simply engage in cost-benefit analysis, because we have limited resources.

Entirely wiping out an enemy population can be incredibly risky as they'll try to also wipe you out in response. It consumes enormous resources as people on your own side get killed, your resources get used up, etc. It weakens your group making you more vulnerable to attack from third parties.

Most of the time, it's just bad strategy.

You don't need to invent instincts or tendencies or claim something is more subtle or targeted when the vastly simpler explanation is just that it's all just cost-benefit.

BurningFrog 16 minutes ago | parent [-]

Which is why you either wipe out the whole population, or not at all.

If you have the type of enemy that holds a grudge across generations, that is.

Should be true for hominids. I have no theory for the wolves.

crazygringo 8 minutes ago | parent [-]

Huh? Most of human history is battles here and there -- gain a little more land and stop, deter the enemy then stop, maybe conquer some people and rule them and extract some resources rather than kill them. Not total peace vs genocide. The idea of it being all-or-nothing is neither usually reality nor usually good strategy.

We were animals. We acted in accordance with our natures. Wolves and chimpanzees aren’t baddies any more than bees or hyenas. Nature is brutal.

Today, however, we are more than our natures. We have the capacity to criticize it when it arises in ways we disapprove of. In a certain sense, humans have a unique capacity to reduce suffering in a way without precedent in Earth’s natural history.

Your argument, written here and As far as I understand it at the moment, goes along with the other argument that everything is a simulation, or that everything that we do is preordained based upon physics. All mindbenders.

I want to believe that I have the ability to make an educated decision when faced e.g. with impulses to suppress or oppress others, I do know that I can consider ramifications and benefits outside of those which directly impact me.

So, perhaps it's better to say, we can be unanimal like rather than simply not animal, at all? What do you think?

I do believe in determinism.

I see what you mean by being able to consider the worth of harming something for your own gain. But doesn't this apply to all animals? If a bear was hungry I'm sure they would happily eat you, but they would probably think twice if they weren't. Same for early humans, it's just we have our technologies (which our intellectual nature has enabled) now to prop us up and not have to really think about survival.

The main thing I'm curious to hear your thoughts on is what are we if not animals? Gods? That's surely completely relative, like an anteater to an ant.

Another way of looking at it is that humans (and apparently our close brethren) are tribal, don't give up fighting easily, and can generationally hold grudges.

Invaders of days gone by knew that even the young kids would grow up to "avenge their people", so to avoid problems (violence/killing against their tribe) in 10-15 years, it's better to just totally erase the population.

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).

And lions. And banded mongooses. And meerkats. And ants.

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.

rhelz 6 hours ago | parent | prev [-]

Every part is unsubstantiated. For starters, for the vast majority of H. Sapiens existence on earth--from 300,000 years ago to about 45,000 years ago, we shared the world with 4 or 5 other hominids that we know about. (Neanderthal, Denisoven, H. Luzonensis, H. Floresiensis, and still perhaps a few H. Erectus, and no doubt even more we haven't found yet.)

That's 250,000 years of coexistence. We know that we sheboinked with at least two other species, probably more, because we still carry their genes to this day. So much so that it couldn't have been just a sheboink or two; we sheboinked over extended periods of time, i.e. we formed families with Neanderthals and Denisovens.

We have no evidence of warfare between the species. I.E. We have found no Neanderthal skull with an arrowhead in it, for example. Besides the fact that we are the only ones left, I don't see any substantiation at all.

It is a mystery why they are not still here. But the last 50,000 years, since the end of the last Ice Age, has been very hard on human species, for some reason. We are the only humans left, what every got them might get us too if we let it.

Thats not correct.

We have a neanderthal slain by spear, at a time and place where it was only carried by modern humans. [0]

This isn't a singular event. We have a history on injuries consistent with war, on both sides.

Yes, we "sheboinked". We also took women as prizes of war and raped them. As humanity has continued to do for most of their history.

Sure, the story is probably more complex. Some tribes at war, others at trade. Some who intermingle, and others who raged. That's... Just history of a people. That's normal.

But we absolutely have a history of war between the species.

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.

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!

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.

throwup238 8 hours ago | parent | prev [-]

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.

abetusk 8 hours ago | parent | prev | next [-]

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].

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).

Thanks for these sources. Archeology definitely is a big known unknown for me, so even getting started reading basic info about this is rough. I appreciate the links and terms.

This youtube channel: https://www.youtube.com/stefanmilo has a lot of good stuff. I don't know enough to know where he's right or wrong, but provides entry points for to looking more into it.

I have gone down a couple rabbit holes based on his videos and while it seems like he's occasionally gotten some facts wrong or misunderstood an argument, I'm pretty confident he's doing a decent job accurately representing the archaeology.

Awesome. I've watched plenty of Miniminuteman (Milo Rossi) videos, but his tend to be more pop-sci/debunking outrageous claims and less foundationally educational. I'll check this channel out too.

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.

> 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?

Pretty much. Being able to transfer/build a fire is a lot easier than starting one. Fire starting requires bow/flint&steel and a lot of patience. Control basically means using simple torches to transfer fire from one place to another (where the initial source is either lightning/wildfire or embers of a previous fire).

walkerbrown 4 hours ago | parent [-]

Some very recently published research (Dec 2025) claims evidence of fire starting among homo neanderthalensis. This would push back fire starting know-how (not only control) from 50k to 400k years ago. Cool stuff!

There's pretty strong evidence that the use of fire to cook food is what enabled modern humans, with their short (and relatively fragile) digestive systems and giant energy hungry brains to evolve. Cooking food makes more calories bio-available in food and also reduced the amount of energy the body needs to expend on that food to harvest calories... so there's more energy available for thinking (etc).

And cooking kills like 99+% of pathogens, which freed us from much of the parasite/disease stress other animals must live with.

When is the first evidence for cooking?

throwup238 7 hours ago | parent [-]

That’s a complicated question. The Wonderwerk Cave in South Africa where we found the first evidence of controlled fire also contained burned plant remains and bones, which could be interpreted as evidence of cooking. There were also burned fish remains found at the Gesher Benot Ya’aqov site in Israel, dated to about 780 kYA, which could also be interpreted as evidence of cooking.

By far the strongest evidence is the Qesem Cave in Israel, which had a central hearth and so many burned animal remains that it couldn’t have been accidental. Unfortunately the dating on that is controversial and the error bar is huge at 300 +- 100 kYA (200,000-400,000 years ago).

dbcurtis 7 hours ago | parent [-]

Thanks! That is much farther back than I thought, even 200 kYA.

I had thought (perhaps wrongly) that our brains got a massive "boost" in capacity when our ancestors moved to coastal areas and the diet was dominated by (Omega 3 heavy) shellfish and crustaceans.

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!

That's true for pretty much everybody. Homeschooled or not. You think everyone shocked by this news was all homeschooled?

No, but I do think it more likely they got a more accurate world history class somewhere along the line. I was taught creationism thanks to the conservatism nature of my family and the area I grew up in. It took a long while to know and accept the world (and universe) is as old as it is.

I went through public elementary and high school. The amount of world history taught there is vanishingly small.

Just for fun, ask some high schoolers who were the major combatants in WW2.

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.

BirAdam 5 hours ago | parent [-]

Well, most cattle aren't given much to stimulate them, and they're bred for meat production and complacency. People aren't exactly looking to make the life of cattle fun or enjoyable.

We have evidence that non Homo sapiens bipeds (e.g., Neanderthals, Homo habilis) used tools far before we came onto the scene. A long lineage of hominin species came before humans!

And even today, our species' cousins (Chimps) are rudimentary tool users. Recently saw a documentary where they evolved their 'tools' to get honey from a 1-stick approach to a 3-stick approach.

The big secret: certain pools of ancient humans have been smart for alot longer than modern evolutionary theory wants to admit

adgjlsfhk1 3 hours ago | parent | next [-]

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.

foxglacier 3 hours ago | parent [-]

Being in a common ancestor is certainly compatible with evolution but it's not necessary because it could have evolved independently in each branch.

PinkSheep 2 hours ago | parent | prev [-]

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.
