Oldest Modern Humans Found

DrLudicrous writes "Anthropologists have reconstructed and dated three skulls from Ethiopia that they believe to be the oldest anatomically modern human skulls in existance. They date to 160,000 years ago, in agreement with genetic studies that pin the arrival of modern humans to at least 150,000 years ago. The skulls also demonstrate evidence of ritual burial." UC Berkeley has the original release as well.

      That's why scientists use different criteria for establishing "intelligent" burials that were done for some purpose beyond just keeping the body safe from scavengers and whatnot. Presence of dyes, plants, tools, and various things are used to determine that sort of thing. Neanderthals buried their dead, but scientists cannot agree if it was done for a spiritual reason, or just to keep the sabre-toothed hyenas away. Neanderthals are quite often given the short end of the stick by scientists.

      It doesn't add up because you have to know the big picture. It has to do with our evolved capacity to suppress non-kin conflicts of interest, using the threat of coercive violence, on a larger and larger scale throughout our history. Every time humans developed a new way to do this, you notice an "adaptive revolution", followed by a period of adaptive sophistication:

      (Dates are fairly approximate)

      ~2 m.y.a. - development of elite throwing: We could throw accurately, and fast enough to kill. This is precisely when the first Homo evolved.

      ~50,000 yrs ago - the Atlatl: a spear-like device enabled us to kill at farther distances. Behaviorally modern revolution occurred soon after.

      ~10,000 yrs ago - the bow: a long distance precision weapon (relative to what was before). The agricultural revolution occurred soon after. This might be what you're referring to as "civilization" in your post.

      ~5,500 yrs ago - Body armor & "Shock weapons" such as swords coincides with the rise of the archaic state.

      ~600 yrs ago - gunpowder/artillery: with gunpowder came the rise of the modern state. Things started to change rapidly after this. Body armor was no longer effective in stopping gunpowder, so we could threaten coercive violence on a larger scale.

      ~400 yrs ago - handguns: different from artillery in the sense that it allowed mostly anyone to possess an accurate, small deadly weapon. The democratization of the modern state occurred. See: The United States of America

      ~50 yrs ago - aircraft and missles: this enables us to effectively coerce non-cooperating persons on the other side of the planet. We are in the midst right now of a formation of a pan-global coalition.

      There was a documentary series about 20 years ago on PBS called "The Ascent of Man" written and narated by Jacob Bronowski. (This is also available as a book)

      In it, Prof. Bronowski posited that civilisation begins with the invention of agriculture approximately 15,000 years ago. It is at that time that the modern grain came into existence. (How, why or when no one knows.) This allowed people to accumulate food surpluses which could be stored. The importance of this is that it allows humans to settle in a single location rather than leading a nomadic existence.

      Now nomads can only keep what they can carry. But a settled farmer can accumulate goods because he is not limited by his carrying capacity. "Well, so what?" you might say. Bronowski made the claim that this leads to the invention of writing. If you have a surplus, at some point you start keeping records - particularly if you have a tribe and a need for distribution of goods. This record keeping starts off with such things as knotted strings or tally sticks, but at some point it starts to evolve into a written language.

      And what is the importance of that? It is this. Animals have only two ways of accumulating knowledge: instinct (passed on by DNA), and what it learns in it's lifetime. These have finite limits. But writing allows you to write down information that later generations can access - and build on. Thus the amount of information available to the species begins to increase - and so civilisation.

      Which shouldn't surprise us geeks. We know that the design of the system influences the behaviour of the system. :-)

    There's too many conclusions drived from too little facts. How can a conclusion be derived about wether they used plants if only the Volcanic Layers and fossils were tested for age? There's no mention of testing or even finding any sort of plant material. Geology researchers (about 98% of them anyways) are not going to know or care about testing for this sort of thing.

    Furthermore, there's no mention of attempting to re-create the environment that the fossils were found in based on geological tests, it seems that theories were based only on the fossils found. (At least that's what I get from the wording of the article). For all we know these fossils were moved from a different area/region/continent. The fossils were found bashed in. Was the bashing the result of being prey for a different, un-discovered predator?

    Also, did anyone catch, near the end of the article, the following quote:

    In this single study area, the team has found fossils dating from the present to more than 6 million years ago, painting a clear picture of human evolution from ape-like ancestors to present-day humans.

    Is it me or is there something REALLY wrong in the fact that such a wide age range of fossils were found IN ONE STUDY AREA? I refuse to accept the fact that ALL of the fossils came from ONE area without some sort of assistance in reaching their final destination.

    I did my U-Grad work in Archaeology and didn't pursue it because of these 'play in my sandbox or else' reserchers and their theories that never hold water.

    While I am a Christian, I must say that the Bible has certainly changed over
    time. It has changed in regard to its content, for there were multiple canons
    competing one against the other before the Jews and Christians each agreed on
    their respective canons, and it took until the late fourth and early fifth
    centuries for the Christian church to finally say, "Ok, so this is the NT and
    the common man will regard these books as Scripture and not others." It didn't
    drop down out of the sky.

    The LXX represents the oldest readings of the Hebrew Bible, and it diverges
    from the Masoretic Text, Hebrew text of today, in a large number of ways.
    There are additions to biblical books found only in Greek. The book of Jeremiah
    is in a different order than in the MT, and I would think the order of a book
    has an impact on interpretation. In many places, there are variations
    resulting from its translation and the MT of today, which cannot be assumed to
    just be in translation.

    The Dead Sea Scrolls, as constructed (it has been noted this is iffy),
    challenge the current Hebrew text as much as they support it. Yes, the DSS
    Isaiah is very close to the MT of today. Jeremiah (again), though, is much
    different. It is much shorter, and again, is in a different order. The
    Penteteuch of the DSS is more favorable to the LXX and Samaritan Penteteuch
    than it is to the MT.

    The above are observations. There are still others which are made about the OT
    and show that it must have been composed in an extended editorial process (the
    Documentary Hypothesis on the Penteteuch, for example). There are places where
    it is clear that something has been omitted. In Numbers, God sends Balaam, and
    then sends an angel to kill him in the way because he went. I can postulate
    that God, as presented in the text, is fickle and kills people for obedience,
    that there was a story in between God's sending him and the ass speaking which
    was omitted and would have explained why he was being punished, or I can see it
    as an oversite in editing together several stories (the Documentary Hypothesis).
    I don't see many other rational arguments for it in the text.

    I could mention more differences and alterations over time in the Hebrew Bible,
    but I don't see a need to. Likewise, I think that my point is made and I do
    not need to proceed into the New Testament to show the great number of changes
    over time in it. That the texts of the books of the Bible has changed is an
    observation. To deny it is either to not look at the evidence or to be wholly
    irrational.

    The truth of the matter is that the earliest men almost certainly would have had straight hair, not curly or kinky but straight, and thin lips, just like most Europeans and Asians today. The wild-type for hair in primates is straight, and all of the great apes conform to that type. Similarly, no ape has thick lips, and our closest living relatives are pretty much lipless. Given these facts, why would any reasonable person expect the "first" men to look like modern day Africans?

    Of course, it is logically impossible to rule out that our species evolved to gain the features of modern-day Africans only to lose them once again, but this flies in the face of both probability and Occam's razor - it is extremely unlikely that a feature, once lost, can then be regained down the line, simultaneously around all of the world outside Africa.

    One mistake people tend to make is to assume that because our species originated in Africa, modern day Africans are somehow "closer" to what we must have originally been like, but this is nonsense. Africans are just as far removed from the original homo sapiens populations as any other population groups, so they've had just as much time to diverge from the original type. Africans, like any other populations, haven't stood still in evolutionary terms, contrary to the misleading notion that this article illustration propagates.
