Takeaways
- 🦍 The concept of non-human primates using stone tools has led to the development of a new field of research called 'primate archaeology'.
- 🌏 Four non-human primate species are known to use stone tools: white-faced capuchins in Panama, long-tailed macaques in Thailand and Myanmar, bearded capuchins in Brazil, and chimpanzees in the Ivory Coast.
- 🕰️ Bearded capuchins and chimpanzees have been using stone tools for at least 3,000 and 4,000 years, respectively, dating back to around the time Stonehenge was created.
- 🔨 Stone tools are used by these primates for various purposes, including cracking nuts, processing seeds, digging, and even as part of sexual displays.
- 🐵 Long-tailed macaques have become so adept at using stone tools that they have destabilized local shellfish populations, potentially leading to a cessation of stone tool use.
- 🌊 Other animals, like bearded vultures and tusk fish, also use stone tools, but primates are the most extensively studied due to the similarities in their tool use to early human ancestors.
- 🔍 Archaeological methods are challenging for studying stone tool use in some animals due to the lack of distinct wear patterns or identifiable characteristics on the tools.
- 🐟 Sea otters are an exception, with researchers finding distinctive usage marks on rocks left by these animals, suggesting they may have entered the Stone Age.
- 🧠 The development of 'flaking', where a rock is smashed to create sharp flakes, was a significant step in human evolution, allowing us to compete with larger predators for food.
- 🏗️ Despite recent evidence suggesting bearded capuchins might be making and using stone flakes, it's unlikely that these primates will rapidly develop technologies to rival humans, considering the slow pace of technological advancement in our own history.
Q & A
What is the significance of non-human primates entering their own 'Stone Ages'?
-The significance lies in the fact that it challenges the notion that humans are unique in their use of tools and technological development. It also provides insights into the cognitive abilities of these primates and their adaptability to their environments.
What is the definition of 'primates' as mentioned in the script?
-Primates are mammals of an order that includes lemurs, bush babies, tarsiers, marmosets, monkeys, apes, and humans.
Which four non-human primates are known to use stone tools?
-The four non-human primates known to use stone tools are white-faced capuchins, long-tailed macaques, bearded capuchins, and chimpanzees.
How long have bearded capuchins and chimpanzees been using stone tools?
-Bearded capuchins and chimpanzees have been using stone tools for at least 3,000 and 4,000 years, respectively.
What is the role of stone tools in the diet of white-faced capuchins?
-White-faced capuchins use stones as hammers and anvils to smash nuts, crabs, and snails to crack open shells.
How have long-tailed macaques impacted their local shellfish population through the use of stone tools?
-Long-tailed macaques have become so adept at using stone tools to prey on shellfish that they have destabilized the local shellfish population, potentially to the point of depletion.
What is the difference between 'flaking' and simple use of stone tools?
-Flaking involves using a hammer stone to break off a smaller, sharp piece (a flake) from a coarse stone, which can then be used like a blade to cut meat, setting it apart from the simple use of whole stones as tools.
Why might gorillas and orangutans not have developed stone tool use to the same extent as other primates?
-Gorillas and orangutans might not have developed stone tool use as much because they spend much of their time in trees where stones are less abundant, limiting the opportunity to learn and pass on the behavior.
What recent evidence suggests that bearded capuchins might be advancing in their stone tool use?
-Recent evidence suggests that bearded capuchins might be making and using stone flakes as tools, although it could be unintentional and just a result of smacking rocks together.
How does the development of stone tool use in primates compare to human technological development?
-The development of stone tool use in primates is similar to the early stages of human technological development during the Stone Age, but humans eventually developed more advanced techniques like flaking, which allowed for greater access to resources and further technological advancement.
What does the script suggest about the future of stone tool use among primates?
-The script suggests that while some primates are using stone tools, it is unlikely that they will develop technologies to rival humans due to factors such as limited resources, habitat constraints, and the slow pace of technological advancement in the animal kingdom.

Oh God
what war don't of the Planet of the Apes
I mean come on it's a great film I mean
it might not be the most scientifically
accurate film out there but I love it
it's probably because I've always been
fascinated by the idea of animals using
tools and solving problems using those
tools which is why it's probably not too
surprising that I got pretty excited
when I heard the news that several
non-human primates have actually entered
their own stone ages and some of them
have been doing it for at least
thousands of years and this has spawned
a whole new field of research called
primates archaeology okay quickly let's
just get a definition out of the way
primates a mammal of an order that
includes the lemurs Bush babies
tarsiers marmoset monkeys apes and
humans for put simply just for the
purposes of this video both monkeys and
apes are primates the four non-human
primates that are using stone tools are
found around the globe there are white
face capuchins in coiba National Park
just off the coast of Panama
there's long-tailed macaques on the
shores of southern Thailand and Myanmar
there's bearded capuchins in brazil's
serra da capivara National Park and
there's chimpanzees in the forests of
the Ivory Coast in Africa and primate
archaeologists dug up sites that showed
that those last two the bearded
capuchins and the chimpanzees have
actually been in their stone ages for at
least 3,000 and 4,000 years so since
around the time that Stonehenge was
created which is a pretty crazy amount
of time now until pretty recently we
humans thought that tool use was one of
the defining features that separated us
from other animals but in recent decades
countless examples of tool use in other
animals has been discovered and
confirmed like octopuses using coconut
shells as protection or crows using
sticks to get access to hard-to-reach
food or gorillas using sticks to measure
the depth of water but long-term stone
tool use is kind of a bigger deal I mean
look we humans are pretty great over
thousands of years of technological
development we've managed to create some
pretty incredible structures and we've
managed to invent some pretty
mind-blowing stuff but it all had to
start somewhere some say that the Stone
Age was one of the most significant
points in our technological journey when
our ancestors entered it over three
million years ago the use of stone tools
massively increased our access to
resources which could have been a key
factor that allowed us to grow bigger
brains which would have allowed us to
create better tools which would have
given us even more access to even more
resources and so on and so on and for
these primates it's doing the exact same
thing it's giving them more access to
resources that they may have had zero
access to before the white-faced
capuchins use stones as hammers and
anvils and smash things like nuts crabs
and snails to crack open shelves the
chimpanzees mainly use them to crack
open a range of different nuts and the
bearded capuchins use them for cracking
nuts processing seeds and fruits digging
and other things like sexual displays
and the macaques which used stone tools
as axes and hammers to pray on things
like shellfish and nuts have become so
good at what they do that they've
destabilized the local shellfish
population and it's thought they might
deplete their local prey populations so
much that they'll have no use for stone
tools so they'll stop using them and
eventually they might forget how to use
them altogether now there are actually
other animals that use stone tools like
bearded vultures that drop bones from
the sky onto rocks to crack them open
and access the marrow inside and tusks
fish have been known to smack clams
against rocks to open them up but these
primates that I've been talking about
are by far the most extensively studied
a problem with these other stone tool
users is that it's hard to find out
about it through archaeological methods
because these stone tools that they use
don't really show any distinct wear
patterns or identifiable characteristics
but sea otters who use stone tools to
pound and crack open things like snails
mussels and clams might be the exception
as recently researchers have found
identifiable distinctive usage marks on
rocks left by the authors so I wouldn't
be surprised if I'm making and otters
have entered the Stone Age video pretty
soon so make sure you're subscribed so
you don't miss it
all of these animal archaeology studies
can teach us a lot about our own history
and development of tool use especially
considering that these primate tools are
very similar to the tools created by our
ancestors in the early days of our Stone
Age but there is a key difference in
technique that might still set us apart
it's a process that we developed called
flaking this is where a rock known as a
hammer stone is smashed against another
rock called a coarse stone in order to
break off a smaller sharp piece known as
a flake these flakes allow us to access
food like never before as they acted
like blades to cut meat straight off of
an animal carcass which were potentially
killed by larger predators like lions so
they allowed us to properly compete with
larger predators for the first time and
the development of this new flaking
process was big as it's not just using a
stone tool it's using stone tools as
tools to make different more efficient
stone tools for extracting even more
resources and this set us apart from
other stone tool users at least until
now you see there's some recent evidence
that these bearded capuchins are
actually making and using these stone
flakes as tools although it might be
completely unintentional basically just
a happy accident of smacking rocks
together but it could get really
interesting if more evidence comes out
to support this whole idea ok alright so
what does all of this actually mean are
these monkeys and apes about to rise up
and build these megastructures and
develop all these technologies to rival
humans well look at it like this after
we entered our Stone Age and
deliberately started making flake stone
tools they remained pretty much
unchanged for a million years and then
once our ancestors started making
refined flat stone axes they then
remained unchanged for another million
years so basically even if these monkeys
are deliberately flaking their stones it
took as a very long time to move on for
them and also they might not even have
the resources the reason that other
great apes like gorillas and orangutans
haven't gotten bored with stone tool use
yet might simply be due to the fact they
spent so much their time in trees and in
areas where stones just aren't really
that abundant so they might literally
just not be enough rocks to learn the
behavior and then
past the behavior on to future
generations and on top of this most if
not all of their habitat is being made
smaller and smaller by human activities
so the time for them to make the most of
their environment the tool use might
have already passed so it's likely that
we won't be seeing too much change but
we could see more discoveries like these
that continue to challenge the way that
we think about ourselves then again
those capuchins have been known to be
pretty fast learners
