In the present study the researchers looked for the source of the raw material used to produce thousands of handaxes found at two prehistoric sites in the Hula Valley: Gesher Benot Ya'aqov, dated to 750,000 YBP [years before present] and Ma'ayan Barukh, dated to 500,000 YBP, both of the Acheulian culture. Prof. Sharon: "Approximately 3,500 handaxes were found scattered on the ground at Ma'ayan Barukh, and several thousands more were discovered at Gesher Benot Ya'aqov. The average hand axe, a little over 10cm long and weighing about 200g, was produced by reducing stones that are five times larger – at least 1kg of raw material. In other words, to make the 3,500 handaxes found at Ma'ayan Barukh alone, early humans needed 3.5 tons of flint. But where did they obtain such a huge amount of flint? Many researchers have tried to answer this question, but our study was the first to use innovative 21st century technologies: advanced chemical analysis and an AI algorithm developed specifically for this purpose."

Interesting.
When I saw “Hula Valley”, I immediately thought it was either in Hawaii or related to that button on my Roku remote. :^)
And that was before Chubby Checker. Impressive.
systematic procurement of raw materials is is is
EVIL
It causes climate change !
It hurts muver erf.
It’s capitalism and and RACIST !!
“YBP [years before present]”
They sure hate to say B.C. Now they are avoiding C.E.
But they want to sound specific instead of saying “years ago.”
No, YBP has to do with radiometric dating. The real threat is the failure of all online sites to use “A.D. 2023” (or whichever year it is).
Shake That Thing!
Not what came to mind when I saw ‘handaxes’. This looks more like apes banged rocks together. Still, interesting.
“YBP [years before present]”
So the article is only accurate through December?
My lawn mower has been making “hand axes” for years. Every time we have an exceptionally cold winter my lawn sprouts more raw materials.
The handaxe factory closed.
It has been happening for a long time.
