How can a stone teach you anything?

76 in origins

Humans are the ultimate throw away species.

We have been picking up discarded tools for millennia and there is even signs of recycling in the archaeological record.

Where good tool making material is scarce its not uncommon to find older tools that have been remade into new tools. Sometimes there may be hundreds of thousand, even millions of years between the time the first tool was discarded and then picked up and remade into something else.

These discarded tools can tell us a bit about those who made them.

It doesn't take a rocket scientist to figure out that there is quite a huge difference in the level of skill, dexterity and brain power required to manufacture the tool on the right in comparison to the tool on the left.

The one on the left (Oldowan) is a pebble that has been crudely bashed on one side to produce a simple sharp edge.

The one on the right (Acheulian) has been carefully planned and worked to produce a flattened instrument with a fine cutting edge all round the perimeter of the stone.

Its not surprising then that the cruder tools are found before the more intricate ones.

There must have been some fantastic advancements to enable the latter tools to be manufactured.

Up till now its simply been educated guesswork as to how this occurred and which homonin species is responsible for these, since there are a couple of overlaps.

Through lots of effort we modern humans have been able to reverse engineer how these tools were created, partially by trial and error and partly by observing and copying peoples that still manufacture stone age tools today.

But to figure out what is really going on brain imaging is being brought on. Participants are having their brain activity levels and areas monitored while they manufacture modern equivalents. This enables researchers to see exactly what areas of the brain were required to manufacture tools and what areas would have been stimulated by these repetitive processes.

Language was thought by previous studies to be key.

Each of the subjects who participated in this study attended multiple training sessions to learn how to make Oldowan and Acheulian tools before going in for the final test – making tools while hooked up to the fNIRS system.

We needed to control for language in the design of our experiment to test the idea that language and tool-making share a common circuit in the brain. So we divided the participants into two groups: One learned to make stone tools via video with language instructions; the other group learned via the same videos, but with the audio muted, so without language.

If language and tool-making truly share a co-evolutionary relationship, then even those participants who were placed in the nonverbal group should still use language areas of the brain while making a stone tool. This is the result we should expect if language processing and stone tool production require the same neural circuitry in the brain.

The results were insightful...

What we found was that only the participants who learned to make stone tools with language instruction used language processing areas of the brain. This probably means that they were recalling verbal instructions they’d heard during their training sessions. That explains why earlier studies that did not control for language instruction in their experiment design found that stone tool production activates language processing areas of the brain. Those language areas lit up not because of anything intrinsic to making stone tools, but because while participants worked on the tools they also were likely playing back in their minds the language-based instruction they’d received.

Our study showed that people could make stone tools without activating language-related brain circuits. That means, then, that we can’t confidently state at this point that stone tool manufacture played a major role in the evolution of language. When exactly language made its appearance is therefore still a mystery to be solved.

It just goes to show what can be learned from a stone and that the interrogation needs to be precise or we may wander off to the wrong conclusions.

To answer the question: I personally got the experience that it is all about how you use the stone. If you are a little child and you throw a big stone in the air and end up hurting yourself because of gravity, you learn your lesson for the rest of your life.. ;)

It's a bit of a shame we no longer make many of our personal tools... I have a paleo hide scraper that I use for craft work as it fits my hand so perfectly! Yes I've used it to scrape hides and also to clean gourds.

One size does not fit all!!

Yup, the custom nature of stone tools is very apparent. some just fit perfectly in your hand others don't, some are made for lefties but most for right handed use.

Man is a recycler of what his predecessors have done, the only difference is that it used to be manual and simple but now uses modern technology and science. In essence what it wants to achieve looks the same in ancient times and now. Ancient humans used stone as a weapon but now humans use iron and even the hardest steel, whereas the desire of the maker is the same weapon. A good post and an inspiration and for us all

I loved the way just a stone is put up into a beautiful article. We do not usually think of writing an article just based on a stone, do we? An excellent approach and a different one too.

Wow, such an informative piece. Who would've thought of this that our part of brain for language is recycling and based on the instructions received while preparing for a task,the same part help us in this archeological response. @gavvet, this piece is really educative and am glad to learning it from you.

I think geology is a scientific field that its not value. In my opinion its one of the most interesting fields that you can learn. In the stones is hidden the secret of humanity but geology has a lot of field where you can stand out:
Speleology
Stratigraphy
Oil Geology
Economic Geology
Structural Geology
Gemology
Historical geology
Planetary Geology
Regional Geology
Geomorphology
Geochemistry
Geophysics
Hydrogeology
Mineralogy
Paleontology
Petrology
Sedimentology
Seismolog
Tectonics
Vulcanology

Amazing analysis. I always thought that progression of man (homo-sapien and his ancestors) developed their abilities progressively and language formed a key factor in their evolution to a species using advanced tools and weapons. Thanks for sharing. Was intriguing.

While I am here, may I make a request - When you have time, please do take a look at my blog where I tried my hand at writing - a chain of thoughts on solitude - inspired by my wildlife picture instead of just putting the picture. Thanks

The experiments and studies with people who possess language probably are not so pure comparing with some language conception due to doing tools with hands and when body language is not enough

I like to think any sort of success or progress is built upon the previous success and progress of others -- tools or not.

This is such a fascinating study with the brain. It shows how the brain works with respect to how we think. I'm even more amazed by the results! You would think that language would have a definitive connection with stone tool manufacture but it just goes to show that the brain is more complex than we know :)

51
  ·  6 days ago

As the article brings out, the complexity of the tool in the making is a factor. I am thinking that it would be easy to see some trees and figure out how to make a house of them. - even chimpanzees are capable of something of the sort. When it comes to sharpening a rock, it's more complicated perhaps, but still wouldn't require much verbal instruction, if any. If, on the other hand, we are talking about more advanced tool making, which might go as far as metallurgy, for example, then verbal instruction is absolutely necessary. Some things just can't be taught to apes. Some things are less intuitive than others. For example, what would make a hypothetical cave man figure out how to melt rock to get iron from it?
I appreciate the article, and agree with the conclusion; good food for thought.

Lead melts at campfire heat.

·

51

That's a fact and I agree. But how many lead rocks have you seen lying around, ready to be melted in a campfire? So many details are involved in the technology that can't be passed on without the means of verbal communication.

Metallurgy definitely followed verbal in the sequence of things

Hello brother and friend @gavvet
Happy Day Hope you are fine and you are all family
I would like to say thank you for the help you give me, and I appreciate that much
We are the sons of one continent and also the sons of the human race, and we have chosen to thank you
As for the relation of the stone with the human mind, this exists actually and I am now very surprised how the pyramids of Giza were built in the time of BC much of the time without the presence of modern tools that are so far we try to a large extent to extinguish the culture of the past peoples
Thank you @gavvet

A quick question. I thought that the weird dating of the old tools is affected by carbon reading method which is regarded to be very unreliable by some theories. Is it so? Please comment. Thx

·
76
  ·  5 days ago

carbon dating only works in relatively recent times, OSL is more reliable for older stuff of the tool nature.

The difference between radiocarbon dating and OSL is that the former is used to date organic materials, while the latter is used to date minerals. Events that can be dated using OSL are, for example, the mineral's last exposure to sunlight; Mungo Man, Australia's oldest human find, was dated in this manner. It is also used for dating the deposition of geological sediments after they have been transported by air (aeolian sediments) or rivers (fluvial sediments). In archaeology, OSL dating is applied to ceramics: The dated event is the time of their last heating to a high temperature (in excess of 400 °C).
Recent OSL dating of stone tools in Arabia pushed the "out-of-Africa" date hypothesis of human migration back 50,000 years and added a possible path of migration from the African continent to the Arabian peninsula instead of through Europe.[2] [3]
The most popular OSL method is called single-aliquot regeneration (SAR).

Our brains are incredibly plastic and open to suggestion. For the most part of our existence we were communication without language. Most of our communication today is non-verbal. All other mammals learn by example from their parents. We are not any different.

·

Yup and nonverbal communication even transcend species. That is immensely powerful, observe an animal long enough and you can begin to predict some of its behavior and even "personality" just by non verbal clues.

One can carve a stone, using a stone.. When asked a sculptor about a statue, his answer was "the figure was already there, i just removed the chips and dust off it".
