Skip to comments.Archaeologists find blade production earlier than originally thought

Archaeology has long associated advanced blade production with the Upper Palaeolithic period, about 30,000-40,000 years ago, linked with the emergence of Homo Sapiens and cultural features such as cave art. Now researchers at Tel Aviv University have uncovered evidence which shows that "modern" blade production was also an element of Amudian industry during the late Lower Paleolithic period, 200,000-400,000 years ago as part of the Acheulo-Yabrudian cultural complex, a geographically limited group of hominins who lived in modern-day Israel, Lebanon, Syria and Jordan.
Prof. Avi Gopher, Dr. Ran Barkai and Dr. Ron Shimelmitz of TAU's Department of Archaeology and Ancient Near Eastern Civilizations say that large numbers of long, slender cutting tools were discovered at Qesem Cave, located outside of Tel Aviv, Israel. This discovery challenges the notion that blade production is exclusively linked with recent modern humans.
The blades, which were described recently in the Journal of Human Evolution, are the product of a well planned "production line," says Dr. Barkai. Every element of the blades, from the choice of raw material to the production method itself, points to a sophisticated tool production system to rival the blade technology used hundreds of thousands of years later.
An innovative product
Though blades have been found in earlier archaeological sites in Africa, Dr. Barkai and Prof. Gopher say that the blades found in Qesem Cave distinguish themselves through the sophistication of the technology used for manufacturing and mass production.
Evidence suggests that the process began with the careful selection of raw materials. The hominins collected raw material from the surface or quarried it from underground, seeking specific pieces of flint that would best fit their blade making technology, explains Dr. Barkai. With the right blocks of material, they were able to use a systematic and efficient method to produce the desired blades, which involved powerful and controlled blows that took into account the mechanics of stone fracture. Most of the blades of were made to have one sharp cutting edge and one naturally dull edge so it could be easily gripped in a human hand.
This is perhaps the first time that such technology was standardized, notes Prof. Gopher, who points out that the blades were produced with relatively small amounts of waste materials. This systematic industry enabled the inhabitants of the cave to produce tools, normally considered costly in raw material and time, with relative ease.
Thousands of these blades have been discovered at the site. "Because they could be produced so efficiently, they were almost used as expendable items," he says.
Prof. Cristina Lemorini from Sapienza University of Rome conducted a closer analysis of markings on the blades under a microscope and conducted a series of experiments determining that the tools were primarily used for butchering.
Modern tools a part of modern behaviors
According to the researchers, this innovative industry and technology is one of a score of new behaviors exhibited by the inhabitants of Qesem Cave. "There is clear evidence of daily and habitual use of fire, which is news to archaeologists," says Dr. Barkai. Previously, it was unknown if the Amudian culture made use of fire, and to what extent. There is also evidence of a division of space within the cave, he notes. The cave inhabitants used each space in a regular manner, conducting specific tasks in predetermined places. Hunted prey, for instance, was taken to an appointed area to be butchered, barbequed and later shared within the group, while the animal hide was processed elsewhere.

Zillah also had a son, Tubal-Cain, who forged all kinds of tools out of bronze and iron.
This is not proof that the Book of Mormon is true.
I wonder if they ever tried constructing a mnemonic memory circuit.
Yes, but that was much later, at the beginning of the bronze age. These were paleolithics.........
Wrong continent, for one............
In a staffing conference, it was determined that Prof. Gopher was the obvious choice to dig in and see what he could find...
A bit startling.
Needs more than Freeper vetting.
Is there a link tp responsible discussion?
When you're an Acheulo-Yabrudian you're an Acheulo-Yabrudian all the way...
From your first blade of flint to your last dying day.
Yes, he was the one who had to go fer stuff............
The prof’s main challenge was keeping Barkai and Shimelmitz happy on the job.
“Hey! Dammit Gopher! Where’s that coffee already?”
He bears a striking resemblance..........
And they have been at war with one another ever since.....
Flint forming for blades does not require powerful blows, just well controlled blows. It is not, BTW, difficult to learn or do.
It is even easier if you cook the flint in a fire. You can flake it then with simple pressure on the blade face.
I tried making an arrowhead the other day. It takes lots of practice...............
Put it in a fire and it will be much easier.
There are sites on the Internet that you might find helpful.
You can use a hammer and cold chisel if you like.
It is a good SHTF skill to have.
Interesting photographs, but I didn’t see any cave? However in the world would they know to dig there?
Hard to say... don't know if the Tel Aviv area was ever populated by bears.
People made edged utensils long before they understood metallurgy or knew how to work metal to produce actual blades. Some primitive people still make edged utensils out of bone, wood, etc.
The most interesting thing I read about all this is ‘Book of the Sword’ by Richard Francis Burton.
Irrelevant if their construction was not using stone knives and bearskins.
Yea, well, this article is somewhat misleading; what they don’t tell you is that there’s significant disagreement about whether the creatures who made these instruments were Neanderthals, (Democrat Ancestors), or modern humans, (everyone else).
The art is holding the work piece, one slip and the old thumb leaves.
Isn’t it kinda hard to hold when it’s H O T ?................
Here is an obsidian blade. Looks very deadly............
It’s also beautiful and aerodynamic. I wonder how they came up with that combo? No computers, just a brain.............
REMINDS ME OF AN OLD JOKE:
A tourist and his family stopped at one of those roadside trinket shops/restaurants out west where they sell Indian souvenirs and handmade artifacts and crafts.
He spotted a box full of arrowheads of all different kinds and sizes, $5 each.
He asked the proprietor if they were real.
“Of course they are real,” he replied. “They are genuine old Indian arrowheads”
Skeptical, the tourist asked where they came from.
“From all over the place, even back of this store,” he countered.
So the tourist bought a couple for his kids as souvenirs and headed them all out to the car.
As they were loading up, he casually walked around the back of the store, and sure enough, he saw that the proprietor was telling the truth.
There sat an old Indian making hundreds of arrowheads............
I did that, too as a kid. Freshly plowed land near a creek right after a rain is the best time.................
That is a really good one.
It looks ‘fresh’..................
I doubt that there could be any of those here in the Southeast, unless they traded for them or the raw materials from western tribes............
I thought it looked too ‘fresh’
Probably was, the same Indian making the arrow heads had those as well, about 250.00 each. Depending on size, he was at the Ramp Festival Roan Mountain Tennessee.
Where’s my flint?......gotta start making some quick!.............
In a related story Prof. Spackler was removed from the project for placing a garden hose in Prof. Gopher’s car and filling it with water and other harassments.
"I was just trying to protect the integrity of the science ya know."
It looks a little ‘fresh’, but yeah I’m drooling too...
the Acheulo-Yabrudian cultural complex
Aren’t these the people Eisenhower warned us about?
while the animal hide was processed elsewhere.
Which if you’ve ever done brain tanned hides
you know why.

Burton's book is a reference standard on the topic. Good choice. I would ping my sword ping list, but I'm on the wrong computer tonight and don't have it handy. Dang...
I looked at that link in reply 39, and saw the newly worked points. It is still a nice specimen.
