Zuma,
I cannot speak for the intent of the original Clovis knappers. I was not there. Nor do I know what they intended.
That being said, other academics have raised a point that I partially disagree with, and partially agree with. Bradley discusses how difficult it is to "master" controlled overshot. I previously posted the information, but then may have been asked to pull the information from the forum.
That being said. I do not know what thoughts ran through Clovis knapper's minds. So, I cannot speak about ancient knapping, in a manner that PROVES intent. I was not in their heads, thirteen thousand years ago.
Here is the Eren et all paper:
https://www.smu.edu/~/media/Site/Dedman/Departments/Anthropology/MeltzerPDFs/Eren%20et%20al%20%202014%20Lithic%20Technology.ashx?la=enOn page two, the author makes three claims. And, prior to making these claims, the author states:
"WE USED EXPERIMENTAL ARCHAEOLOGY TO TEST..."
Do you see those words? They are basing their arguments on EXPERIMENTAL ARCHAEOLOGY. And, you can also see that an experimental archaeologist (Patten) is being cited.
So, I am telling you that the premises, and arguments, of this paper could be FLAWED, if they are basing everything on the work of experimenters, such as Bradley and Patten. I am also introducing the same type of evidence, that these academics are basing their arguments upon. Only, my evidence is more expansive because I cover actual technologies, and they do not. Do you see that? Do you see that I touch upon hammerstone tech, billet tech, and deer tine tech? What technologies do they cover? Is it even explained.
That being said, if we are discussing hammerstone tech, I believe that most all overshots are accidental. If we are discussing billet tech, I think that overshots is difficult to achieve - AS NOTED BY BRADLEY. If we are discussing tine-based "pitching tool" tech, I think that regular flaking, coast to coast flaking, and overshot, is all fairly easy to achieve. If you don't want modern experimental evidence introduced, you need to go back and look at the paper, because they are citing the results of modern experimental evidence.
Bradley's argument is that controlled overshot is a sign of super knappers, and it is recognized in Solutrean knapping, as well as Clovis. As a matter of causality, they link A to B. Eren's claim is that A could not possibly B linked to B, and there are holes in these theories about Solutrean overshot, and Clovis overshot.
My argument is that the discussion does not begin, until one ascertains how the overshot was created. My argument is that they are starting out with a flawed premise. And, if push comes to shove, I can introduce the very same type of data that they are relying upon - EXPERIMENTAL ARCHAEOLOGY. Aside from that, no one can PROVE the intentions of the original knappers, because we were not there.
In nine pages, not a single word is devoted to explaining HOW they believe that the ancient overshots were made. So, as far as I am concerned, they never made it to the starting line.
