These Tools Upend Our View of Stone-Age Humans in Asia

Long ago in what's now southern India, early humans showed a knack for disruption that would've made Silicon Valley tech wizards envious. Over time, the ancient innovators rejected bulky hand-axes and cleavers, instead opting for sleek flakes of stone meant for cutting and tipping spears.

Similar disruptions occurred in Africa among the forebears of modern humans around the same time. But the timing of the Indian transition, spotted in the soil layers of a site called Attirampakkam, is eye-popping. At 250,000 years old—and possibly up to 385,000 years old—this tool transition occurred far earlier than it did at other sites in India.

The discovery, described in Nature on Wednesday [DOI: 10.1038/nature25444] [DX], pushes back the start of what's called the Middle Paleolithic culture in the region by more than a hundred thousand years. That, in turn, could reshape how scientists view the global spread of hominins—humans and their ancient relatives—before modern humans migrated out of Africa some 60,000 years ago.

Earliest Human Remains Outside Africa Were Just Discovered in Israel

For decades, scientists have speculated about when exactly the bipedal apes known as Homo sapiens left Africa and moved out to conquer the world. That moment, after all, was a crucial step on the way to today’s human-dominated world. For many years, the consensus view among archaeologists placed the exodus at 60,000 years ago—some 150,000 years after the hominins first appeared.

But now, researchers in Israel have found a remarkably preserved jawbone they believe belongs to a Homo sapiens that was much, much older. The find, which they’ve dated to somewhere between 177,000 and 194,000 years, provides the most convincing proof yet that the old view of human migration needs some serious re-examination.

The new research, published today in Science [DOI: 10.1126/science.aap8369] [DX], builds on earlier evidence from other caves in the region that housed the bones of humans from 90,000 to 120,000 years ago. But this new discovery goes one step further: if verified, it would require reevaluating the whole history of human evolution—and possibly pushing it back by several hundred thousand years.

    From here [soylentnews.org]:

    Modern brain shape (to say nothing of function) goes back at least 40k years, and anatomically modern bodies go back at least 300k years.

    That's a long time! Our modern civilization could have developed 8-to-60 times in a row.

    In only 150 years, the Titanic won't exist at the bottom of the ocean.

    It is said that Atlantis sank into the sea, but that's unlikely; we know only that water levels have risen by hundreds of feet since the last ice age. It seems likely to me that Atlantis was a global civilization that lived on the coasts of the world (just as our modern civilization does), and thus got inundated in what became known throughout the world's myths as "The Great Flood"; Atlantis was a civilization of megalithic architecture and religious astronomy, and its cities have been sitting in the depths not for centuries, but for millennia, so that they have been virtually obliterated by time. All that remains are a few mysterious megalithic structures on dry land, many of which have been built atop by later peoples, and thus mis-attributed.

    Where will our Civilization be in 10 thousand years?


    Yet, even our modern Civilization's engineers (with their modern tools) become confused by what the ancient people achieved with massive, precision-cut stones.

    So, your argument doesn't really work, now does it? In some things we are more knowledgeable, while in others, they were more knowledgeable.

    Megalithic structures exist, and we don't know how.

    There is ancient stonework that defies even our modern technology; we would not only struggle to lift many of these stones, but we find the exceptional craftsmanship difficult to reproduce even with computer-controlled diamond-based cutters.

    We have no idea how they did it, or who did it.
    This includes stonework [mis-]attributed to the ancient Egyptians, the Inca, the Romans, etc.

    YouTube it.

      People have noticed that certain stone structures have incredibly precise alignments to astronomical phenomena (such as as stars, constellations, solstices, equinoxes, etc.), but that such alignments only become obvious if they were built many thousands of years before civilization is officially supposed to have begun.

      There are even indications that there was knowledge of the Precession of the equinoxes [wikipedia.org], which not only suggests a very sophisticated system of astronomy, but one that must have involved centuries of meticulous recording.

      Add to that the fact that Earth's history has been punctuated by many enormous cataclysms over the last 150k years, and you get the idea that Civilization might have begun several times.

        We are finding tiny artifacts from 200-300 thousand years ago. However we find nothing at all about the supposed civilization that lived, say, 50,000 years ago. That civilization, being able to construct megastructures, had to have a bit more tools than a cave-dwelling tribe that uses flint tools. Where are those tools? Would it be reasonable to suggest that they lived, say, 500,000 years ago, chasing the cave people away?

            Many materials that we use for cutters are ceramics. They don't rust, don't decay and will survive for a very long time. Those should have been found. Ask yourself a question: why would a civilization like ours today build all those huge structures? For what purpose? The existing megastructures do not look useful to a techno civ. The leftovers of the Baalbeck site indicate that the building was constructed inefficiently, that's why it fell apart in an earthquake. Those are contradictions. We can definitely claim that those walls and foundations were built by invaders from space (since they left no trace of their existence) but this still doesn't quite answer what they are good for. Why would extraterrestrials build temples for talking monkeys?

          They are always the unique, incredibly high-precision foundations of other structures, or they are buried (sometimes deliberately) or sit as ruins.

          Go look up Göbekli Tepe [wikipedia.org] for an example of the first archaeological find that really made the "mainstream" historians start to re-think their understanding of humanity's past.

          Also, a whole continent's worth of coastal land has been swallowed up by the rising oceans; archaeologists tend not to go looking in hundreds of feet of water, because their view of history "informs" them that there cannot be anything down there, and even if there were, our own titanic wouldn't last but a few centuries, so what of the materials of a less industrial civilization?

          Also, we live today among hunter-gatherer peoples; there are reportedly some tribes in the Amazon that don't even know our Civilization exists.

          Please, there are a lot of resources on this topic now. Don't sit there smugly thinking you've got it all figured out, because you don't. There are a lot of questions, and 100s of thousands of years of obscure history.

      The best explanation I've seen for that legend is the Santorini event [wikipedia.org].

      A supervolcano created a tsunami that creamed the north shore of Crete and took out the Minoan civilization there somewhere between 1642 BCE and 1540 BCE.

      If the watery end was a gradual thing, it seems logical that the Atlantians would have moved inland and just carted their stuff with them.

        Plato says that Solon (c. 638 BC – 558 BC) visited Egypt, where he was told that 9000 years before, tragedy befell Atlantis in an abrupt cataclysm.

        So, this story depicts an event far further in the past than yours.

        Moreover, the date ~9500 BC coincides with the abrupt, downright cataclysmic end of the Younger Dryas [wikipedia.org] period, which also began in an abrupt, downright cataclysmic fashion; indeed, there is growing evidence that Earth may have been struck by devastating impacts.

          Plato also claims that Athens whupped Atlantis in a straight-up naval fight 9000 years before. Where's the evidence that Athens has been around for 11,000+ years and had a navy back then?

          The way that even a simple phrase being transmitted faithfully through a small number of people over a span of a minute fails repeatedly doesn't have me putting much faith in twice-told tales.

          When there's something in writing that goes back about that far which corroborates the story, that will be a starting point WRT "proof".

          In the meantime, I find the Carbon-14 evidence in Crete more compelling.

            Your thought process made sense until they found Gobekli Tepe, which informed us that mankind was a great deal more advanced in the deep past.

            That megalithic site (which is enormous) was (according to the carbon dating) deliberately buried around 8000 BC, which means it existed before then.

            There's more than enough room for Atlantis in history.

            Furthermore, the megalithic site known as "Puma Punku" in Peru would sit nicely at the edge of lake Titicaca when its water level was higher... around 12 thousand years ago! Interestingly, that's the date to which certain Peruvian megaliths align astronomically.

      The DOI is always useful. You can put it in a search engine, and even use it to look up and pirate the paper cough cough.

      I put (DOI: 10....) when the article is paywalled, and (open, DOI: 10....) when it is freely available.

      As for the DX link, someone complained about me linking to the current direct URL of the paper, which could be subject to change. The DX link links to dx.doi.org/10.blahblah or doi.org/10.blahblah which should redirect to the correct location no matter what (in theory).

      If there is an arXiv link for a paywalled paper, and I notice it, I will throw that in beside all that other stuff. There isn't an automatic way to find this out since arXiv isn't linked to the final form of the paper in any database I know of.
