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.

      As you seem knowledgeable of this topic and it is super interesting, any books you would recommend that gives a good broad overview of all of this?

      • throwup238 5 days ago

        I don’t read popsci but if you’re interested in a rigorous treatment I’d recommend The Human Career by Klein which has the broad overview and The Human Past edited by Scarre which is more of a textbook.

        I mostly just read the papers as they are published but I’ve heard good things about those two books (they’re on my reading list but I haven’t read enough to form an opinion)

      I think a quite unexpected (but more common sense) picture begins to emerge:

      1. Language already emerged with early hominins (paranthropus and such).

      2. Habilis et al developed toolmaking to a level that carrying stuff around was of critical importance.

      3. H. erectus emerged from walking, and brought technology to a "civilized" level.

      4. Anything post erectus evolved for civilized society.

      5. The destruction of soils in eurasia about 24000 BC

      6. The destruction of soils in the Americas about 9500 BC

      7. Old metallurgy age.

      8. Tin bronze age.

      9. Recorded history.

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?

  • ryan_j_naughton 5 days ago

    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!

      Last I knew, the 3.3 mya evidence from the site Lomekwi 3 in Kenya was debatable, though a serious possibility, and the 2.58 mya evidence from the Olduvai Gorge in Tanzania was considered the sure thing.

      Also, more than primates use tools: Many corvids (crows, ravens, etc.) do, as do other animals. Look up New Caledonian Crows in particular.

      But don't take all this from HN commenters debating each other; find some authoritative sources. A recent review article in a scientific journal would be a great start. Google Scholar lets you search for review articles.

  • adgjlsfhk1 5 days 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 5 days ago

    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.

  • bandrami 5 days ago

    Just to throw this distinction out there, what makes something a "tool" isn't that it is used but that it is fashioned. Plenty of animals use things to accomplish tasks; the processing of materials to fashion tools is much more rare.

> 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.)

    I honestly have no clue what word you used was 'charged'. Considering any of those words charged makes me worry how far political correctness has gone! (I'm assuming, I suppose, politically charged?)

    • throwup238 5 days ago

      “Genocidal” is charged because it projects human morality onto non-human animals. It’s about basic scientific hygiene, not political correctness.

      • nandomrumber 4 days ago

        That’s not why genocidal is a charged word in my opinion.

        It’s because it implies that genocide has always been, and will always be, a reality humans will all too frequently find them selves having to contend with.

        An aspect of our evolutionary success that will haunt us always, at least while its not busy being indulged in.

  • nomel 5 days ago

    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).

    • nandomrumber 4 days ago

      This was worth reading, thank you.

      The line between good and evil runs straight down the centre of every human heart.

      And dogs / wolves too, and definitely many / all cetaceans, because they are also cursed with the ability to be deeply affected by the presence, and absence / loss, of those they form bonds with. And that drives us all to be prepared to kill, or at least encourage others to, not out or physical necessity (nutrition) but retribution.

      I’ve always considered the criminal justice system to be a euphemism for the codified retribution system.

      We live in an unjust realm. All we can ever hope for is something approximating an appropriate level of retribution.

      And it is a would appear as fact that that not infrequently rises to the level of not just genocide as we are familiar with it most recently, but proper extermination.

      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.

      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.

    > (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.

      What part of the study strikes you as unsubstantiated?

      • rhelz 5 days ago

        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.

    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.

    We have the unique ability for genocide but also the unique ability to invent sophisticated tools, one of which is culture, whose functions include ways to override our impulses in ways we deem valuable.

  • crazygringo 5 days ago

    > 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.

    • to11mtm 5 days ago

      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 5 days ago

        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.

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.

  • ErroneousBosh 5 days ago

    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.

The precise meanings of "SJ12 YPF", "Y196 NBA", "RFS 131Y", or "R420 BRL" will remain lost to the depths of time.

  • throwup238 5 days ago

    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.
