Modern humans may have evolved more than 80,000 years earlier than previously thought, according to a new study of sophisticated stone tools found in Ethiopia.
The tools were uncovered in the 1970s at the archaeological site of Gademotta, in the Ethiopian Rift Valley. But it was not until this year that new dating techniques revealed the tools to be far older than the oldest known Homo sapien bones, which are around 195,000 years old.
Using argon-argon dating—a technique that compares different isotopes of the element argon—researchers determined that the volcanic ash layers entombing the tools at Gademotta date back at least 276,000 years.
Many of the tools found are small blades, made using a technique that is thought to require complex cognitive abilities and nimble fingers, according to study co-author and Berkeley Geochronology Center director Paul Renne.
Some archaeologists believe that these tools and similar ones found elsewhere are associated with the emergence of the modern human species, Homo sapiens.
"It seems that we were technologically more advanced at an earlier time that we had previously thought," said study co-author Leah Morgan, from the University of California, Berkeley.
The findings are published in the December issue of the journal Geology.
Desirable Location
Gademotta was an attractive place for people to settle, due to its close proximity to fresh water in Lake Ziway and access to a source of hard, black volcanic glass, known as obsidian.
"Due to its lack of crystalline structure, obsidian glass is one of the best raw materials to use for making tools," Morgan explained.
In many parts of the world, archaeologists see a leap around 300,000 years ago in Stone Age technology from the large and crude hand-axes and picks of the so-called Acheulean period to the more delicate and diverse points and blades of the Middle Stone Age.
At other sites in Ethiopia, such as Herto in the Afar region northeast of Gademotta, the transition does not occur until much later, around 160,000 years ago, according to argon dating. This variety in dates supports the idea of a gradual transition in technology.

I saw this article on National Geographic.com today..The thread is the Headline.
I find it interesting that now we are getting closer to the time frame for some of the more "unconventional" claims made about finding tools that are 400,000 years old. I believe--without checking--that those mining sites in California had recovered objects believed to be 450,00 years old? (could be wrong here)
So..here we are..constantly pushing back dates from homo sapiens yet again...
Sorry I couldn't post a link but the gist of it is that these scientists are saying such tools couldn't have been made from some of the more primitive strain of humanity.

BY THE BY--Could someone else link the previous threads about all the discoveries about human settlements and tools whose age has been claimed as bogus? I recall the California one but also remember something about a scientist in Mexico ruining her career on some VERY old objects she found.

Steen-McIntyre's work involved dating a handful of artifacts found in Mexico. These artifacts were never hidden away, the findings were (eventually) professionally published, and subsequent investigations showed why the dates she arrived at were likely wrong.
She herself didn't believe the dates she got - they went back to the time of Homo Erectus. But she published them anyway because of a political situation that was about to shut down the excavation - and later it was closed for a number of years due to political gamesmanship.
This wiki page can tell you abou the "controversy." Please note that that particular page states near the end that:
...Steen-McIntyre’s career as a geologist was effectively finished.
Which is pretty much untrue, as her presentation of a paper this year concerning this topic at a conference in 2008 would indicate.

Harte...
Much thanks for that info on Virginia. She was the one for sure..also..I think the objects in CA weren't the same from those "coal hoaxs" Wasn't that something about a gold chain being found in coal?
Originally posted by atlantiswatusiI believe the information was from a mine in California where in the late 1800's maybe early 1900'2 they found tools in the rocks that have been said to be 400,00 years old. I think they have disappeared but can't be sure.

My main point is that we keep coming closer to the number of 400,00 which is a age that has been claimed on different tools found in different sites. I see a lot of stuff on here from all sides that sounds to be solid at face value--but our past keeps marching ever backward.
In my opinion..it makes legends like Atlantis more probable as we push back our development!

Yes the date is going back as more and more evidence is found to support earlier dates for the start of various parts of what we define as civilization. The 5,000 year date has been long out the window by the way.
Of course the key point is to define what civilization is and how you measure it. By some measures you can take it back to 9,000 BC and by others to 14,000 BC.

I erred in making a statment about atlantis without some explination:
What I meant to say was...as we keep pushing back the time line for homo sapiens and their "development" We must keep an open mind and not discount that an advanced civilization could have existed before.
With so many holes..the point I will hammer home repeatedly is is is irresponsible to say such and such could NOT have existed because we haven't discovered it yet.

Forget Atlantis...I believe it is a fascinating story...but just that. It's just so easy to throw that damn name around everything I speak of a unknown culture.

HARTE--what I mean is that I have tried to look for the hoax parts. Maybe I need to expand my parameters but I keep coming back to some of the same tired sites that talk abotu the "consciousness" of Atlantis, the crystals, physic crap, flying vechicles. I think someone watched the Disney verison of Atlantis and got carried away. The skull thing I have known about for a while as a fake. After all..anything George Lucas decides to put in a movie must be bullcrap....ooops..the church is after me now! LOL
Originally posted by atlantiswatusiLets just say..that as a new face here...I'm also looking for help with some of this stuff because the web is flushed so full of crap. Plus..I'm getitng to know my way around the postngs and my options here...So..I will improve! I will admit..I couldn't find the links I needed. So I passed the buck!
Thanks above guys for the links and information..I'm going to give them a once over!
