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.

This somewhat contradicts the subheading, no?

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.
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?

Thanks! I'll add them to my reading list for today. Its going to be interesting, I can already tell.
To put it into perspective, we did not invent fire.
Well, nobody did, because fire was likely used for tens or hundreds of thousands of years before anyone figured out how to make fire on demand.

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.
> 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.
I heard that fear being muttered mostly about everything going digital and that's much harder for archaeologists to dig up than paper or stone tablets.
However, that's all nonsense, of course: the stuff that people bother to write down is seldom all that interesting. Who cares about who was king or whatever? The real juicy bits are all in our garbage dumps, and we are producing garbage that'll last much longer than anything the ancients could muster. What with all our metal, glass, plastic etc.
> 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 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.
> won't be able to google image anything interesting related to "non-human hominids"
We were a large family [1].
> Real "are we the baddies?" moment
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.
Of course we are the baddies. That’s the narrative every time people need to defend terrible behavior lead by sociopaths: but that’s just human nature. Very practical fallback.
Army ants do something similar as well.

> (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.
Agree with your this-is-not-unique-to-primates take. But why is genocidal not accurate?
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
Animals being tasty is a trait we heavily select for. I don't think chickens have any of the traits you describe but they're certainly not at risk of extinction.
It’s an interesting interpretation, but it’s sounds all very unsubstantiated. Speculation it seems to me.
> sounds all very unsubstantiated. Speculation it seems to me
What part of the study strikes you as unsubstantiated?

It’s so cool and strange to think we have examples of tools that literally predate humans.
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!

I assume these are made of stone? What kind of tools?

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.

So cool! Thanks for the info.
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.
