Evidence Found for Earliest Modern Humans

Hugh Pickens writes "Researchers at Arizona State University report that they have pushed back the date for the earliest modern humans to 164,000 years ago, far earlier than previously documented. Paleoanthropologists now say that genetic and fossil evidence suggests that modern human species — Homo sapiens — evolved in Africa between 100,000 and 200,000 years ago and in seeking the "perfect site" to explore for remains of the earliest populations, researchers analyzed ocean currents, climate data, geological formations and other data to pin down a location. "The world was in a glacial stage 125,000 to 195,000 years ago, and much of Africa was dry to mostly desert; in many areas food would have been difficult to acquire. The paleoenvironmental data indicate there are only five or six places in all of Africa where humans could have survived these harsh conditions," said Curtis Marean, a professor in ASU's School of Human Evolution and Social Change. Photos from the cave at Pinnacle Point in South Africa show where the team found ochre, bladelets and evidence of shellfish — findings that reveal the earliest dated evidence of modern humans."

    I long ago read that the Homo Sapiens arised in an extremely harsh environment that created a strong selective pressure in favor of intelligence and advanced social interactions. But the article says that the researchers focussed on the area where the less evolved pre-humans could have survived easier.

      You're right that this finding does contradict the traditional savannah theory of human evolution, as do many other findings, but it fits right in with the ever increasingly popular aquatic ape theory of human evolution.

      The idea is basically that as the climate dried up human ancestors stuck closer to rivers and oceans, where the trees and water were, and ate shellfish and other seafood. (It doesn't mean we became fully aquatic, like mermaids. Just that we became as aquatic as we are now.)

      The rich seafood diet has plenty of all the stuff needed to fuel a large brain. It also explains why we can hold our breath and babies can instinctively hold their breath underwater, and why we have no body hair, downward pointing nostrils, webbed fingers, dilute urine, and why we find homo fossils in sediment but not chimpanzee fossils, and why baboons, which came down from the trees and onto the savannah, didn't become human-like, etc, etc.

      The savannah theory says that as the climate dried up human ancestors that had previously lived in trees started to move out into the savannah.

    It should be pointed out that there is a difference between something that looks human, and something that acts human and is described as. The "looks human" date has been pushed out and has always been further out than the "acts human" date. The "acts human" date still remains circa 40,000 to 60,000 B.C. (at least last time I heard).

      This actually brings up one of my serious hangups with the currently accepted view of history. Forty thousand years is an incredibly long amount of time. Consider that the ancient civilization of Sumeria (Epic of Gilgamesh) is only dated at 3100 BC with the first evidence of civilization in Egypt also around that time. How much has happened in the last 5000 years? Consider that we even consider the Dark Ages as ancient history and that was only 1000 years ago. We know very little about the history of that time.

      When you consider the advances that mankind has made in technology over the past 5000 years, it is astounding. It is even more astounding to think that for the preceding 35,000 years, there was virtually no technological advancement at all! Now we hear that the date may be pushed back even further, and my incredulity grows.

      The picture gets even more murky when you consider population growth. Population only really stagnates in a primitive society based on limited resources. Even with the worst estimates of the extent of impact from the last ice age, there would be plenty of land mass available for very habitable land for man to expand into. If mankind had been reproducing for 35,000 to 200,000 years, would we not have many, many more people today? Something is just not adding up here.

    Disclaimer: I'm not advocating anything here, just asking from the point of speculation...

    The old accepted model of human development is that man in his modern form, homo sapiens sapiens, appeared 30k years ago with recorded history marking the rise of civilization some 6000 years ago. The theory is that humans lived in nomadic hunter-gatherer tribes until the end of the last ice age. With the warming of the climate, agriculture became possible and with it the surplus of food that allows for civilization.

    Ok, that's the accepted model. But I've always wondered about the likelihood of human civilizations from before accepted recorded history. As I understand it, the science points against it because if there were such civilizations, we should see some proof of it. But what sort of proofs would civilization leave behind and how long would they last with the passage of time? Most human populations like along coastlines and we've seen historic records of cities lost to rising waters. There are many underwater archaeological sites being explored along the English Channel. And when one considers the destructive power of a 2 mile tall wall of ice rolling over a city, what would even be left for us to see? If there were a Hyperboria, a Lemuria, a Mu, what remnants should we expect to see of them, if any?

      That is, in part, the theory behind Graham Hancock's Underworld. He also wrote Fingerprints of the Gods. The books are fun reads and great ways of trying to concoct elaborate and somewhat plausible theories based on scant evidence. They are sort of like the DaVinci Code in that sense. I have found a few good theories that may take some time to prove or disprove in the works although most of them are more fun than science.

      I used to constantly bring up some of these ideas a parties with non-professionals or semi-professionals who had their own notions about pre-history and was always severely admonished. I then always countered that Continental Drift was dismissed by nearly every scientist as a crackpot theory until about 50 years ago.

      Although I doubt the existence of a global civilization prior to 6,000 years ago, I am still keeping an open mind that some form of civilization prior to 6,000 may be out there hidden away under the water or beneath some layers of unexplored dirt. I also keep open the possibility that although worldwide trade did not likely exist, there was the possibility of intermittent contact between civilizations that led to cultural borrowing such as agriculture, written language, and architecture between the Old World and the New.

    What is new in this article is the early date for the use of ochre dye, small "complex" tools, and shellfish in the diet which are all taken as evidence for modern-like human cultural behavior at 165,000 years ago.

    As I posted elsewhere under this article, this just doesn't make sense to me from a historical and technological development standpoint. Known history from the most ancient civilization dates back to only 5100 BC with Sumeria ("Epic of Gilgamesh"). Since that time, there has been incredible advances in human civilization. But this evidence is saying that for 160,000 years, there was virtually no technological development. There would also be virtually no population growth.

    We cannot even fathom that 160,000 years is. Even the dark ages seem incredibly ancient in our minds, and that is only one millennium ago. I find it incomprehensible that in 160,000 years that human beings as intelligent and creative as we are today failed to have any technological innovation in all of that time. Agriculture really is not that big of a stretch intellectually. Can someone explain how this is even plausible?

    There was a 19th century minister who thought he'd found the way to reconcile Wilberforce and Huxley.

    His reasoning went like this. When Adam was created, what kept him from immediately fainting away with hunger? Obviously his bloodstream and digestive tract contained food and its metabolites - remnants of meals he never ate. A human body isn't just a machine, it's an ongoing process. The muscles and skeleton are not just the products of inheritance, but of years of growth and exercise that in Adam's case never happened.

    Therefore, to create a human, God had to create a body that perfectly bore the marks of a history it did not, in fact have. What if God made the entire world that way? If natural selection is a fundamental to the operation of the world as metabolism is fundamental to the operation of the body, then certainly the world would bear the signs of evolution in the same way Adam's body bore the signs of having had breakfast that morning (note also this argues for Adam having a belly button). There would be no point in arguing over whether human precursors disproved creation, because the logic of creation requires them to be there. There would be no point in arguing over whether those precursors ever, in fact, existed, beause there would be no empirical observation or theological argument that could sway the question one way or another.

    The minister was thrilled. Surely people would live and let live, go back to the things they knew best and leave others to do what they do best, unmolested. Unfortunately, this shows that while he was a clever man, he didn't understand human nature very well.

    Quite plausible.

    See here. Development of agriculture is a stretch - it requires the right environment, the right stock to start from, and a long period of 'unconscious breeding' (by picking the best/tastiest/largest examples and, like birds, spreading the seeds around, etc.) to turn that wild stock into something that can actually be planted and managed to support a population.

    You look at, say, modern wheat and thing, "sure, any idiot can see how useful it is". But it only became that after a long period of development from wild stock. Try to live off the wild stuff and you'll either switch to hunter-gatherer or starve.

    "they feel if the Creation story is an allegory, what else is an allegory?"

    Interesting argument, but a logical fallacy.

    On this basis we should reject the "Good Samaritan" as a parable (i.e. a fictitious story): "If the 'Good Samaritan' is a parable, what else is a parable?"

    The obvious reply is: "Whatever else has the characteristics of a parable."

    The very early stories in the Bible have a few features in common with figurative stories - e.g. the story of the Garden of Eden has a talking snake (and explains how he begins to crawl); an idyllic garden; an infinite and invisible God who goes for walks in the garden and acts as though he cannot see Adam hiding behind a bush; one or two "magic" fruit trees that give you either all knowledge, or immortal life; a man called "Man" (="Adam" in Hebrew) and a woman called "Life" (="Eve" in Hebrew) - i.e. in the literary context, these characters are very plausible representatives of the whole human race, rather than actual historical people; etc. If you insist that the story "must" be historically accurate narrative, then you will dismiss all these literary characteristics. But if you start from the position of "I don't know beforehand what kind of genre ytis passage is", then the signs are all there.

    In other words, the Bible is certainly a mixture of literary genres, and you have to work out what kind of genre any passage is by considering its literary qualities. Fundamentalists try to dictate what the genre is. They build a castle of faith based on their *fallible* claims about what a passage "must" means, and then call it *infallible* because "they are just believing what the Bible says". No they are not. They are believing a very fallible human interpretation of the Bible, and then calling *their interpretation* "the Word of God". This is self-delusion.
