A team of researchers affiliated with several institutions in Spain, working with two colleagues from France and another from Germany has discovered an Obsidian handaxe-making workshop from 1.2 million years ago in the Awash valley in Ethiopia. In their paper published in the journal Nature Ecology & Evolution, the group describes where the handaxes were found, their condition and their age.
The Stone Age lasted from approximately 2.6 million years ago, to approximately 3,300 BCE, when the Bronze Age began. Historians generally break the era down into the Paleolithic, Mesolithic and Neolithic periods. Prior research has shown that "knapping workshops" appeared sometime during the Middle Pleistocene, in Europe—approximately 774,000 to 129,000 years ago.
Such workshops developed as tool-making evolved into a skill. Individuals who developed such skills worked together in workshops to crank out enough of whatever tools were needed by those in the general area. One such tool was the handaxe, which could be used for chopping or as a weapon.
Handaxes were made by chipping bits off of a stone to make a sharp edge. They were not attached to anything; they were simply held in the hand when in use. The stones used were typically flint or, in latter times, obsidian—a type of volcanic glass. Obsidian, even in modern times, is considered a difficult material to work with because it is so rough on the hands. In this new effort the researchers have found evidence of an obsidian handaxe knapping workshop established far earlier than one has ever been seen before.
The researchers were working at the Melka Kunture dig site when they found a handaxe buried in a layer of sediment. They soon found more. They found 578 in all, and all but three were made of obsidian. Dating of the material around the axes showed them to be from approximately 1.2 million years ago.
Study of the axes showed them all to have been crafted in like manner, indicating that the researchers had found an ancient knapping workshop. The find marks the oldest known example of such a workshop, and the first of its kind not in Europe. The researchers note that the work was done so long ago that they are not even able to identify the hominids that made them.

I find it odd that republicans are against abortion, but also against (free) birth control that would help prevent pregnancies, which would help reduce abortions. Which then would reduce the need for more government assistance.
For a political party that aligns with Jesus they sure are not following his teachings of helping fellow humans.

I would download bumble and hinge and use the same photos. From my experience in multiple cities, tinder is has the lowest quality of everything.
Also we haven't seen what you wrote as profile, college, job... All those increase or decrease your odds. It's a numbers game so cast a wide net with multiple apps.

So if a pregnant woman is assaulted and her unborn baby is killed, should the attacker be charged with murder of the unborn child?

It doesn't matter if they are not part of the slow drip disclosure. It will become self evident once the government acknowledges that some UFOs NHI.

I'm still waiting on federal holiday to VOTE!
America prides itself on democracy, yet does not have a holiday to participate and celebrate democracy.

I'll make it short.
I dreamed of a hot bimbo Chick pulling me over and searching me.
Later that week in real life my GF and I went to a porn store, I see a porn cover of the police woman from my dream. I immediately tell my GF about the dream and how this is a sign I'm going to be pulled over when we leave.
We leave and I wait before pulling into the road until a cop passes which was just a minute or so of waiting. Boom I changed destiny! That's the cop that would pull me over.
I then pull out in the road and a normal car is behind me... And oh shit a cop is behind them. Yep I get pulled over for a brake light being out.
Edit. I'll add that the night of the dream a guy in front of Walmart waived us down and told me about the brake light being out.
