Scientists confirm Ethiopian fossils are oldest human skulls quote: Two Ethiopian fossils have been crowned as the oldest known members of our species. An estimated 195,000 years old, the pair were witness to the earliest days of Homo sapiens.The discovery adds yet more weight to the argument that Africa, and Ethiopia in particular, was the birthplace of humans. The dating sits well with genetic analyses of modern populations, which suggest that H. sapiens first appeared in Africa around 200,000 years ago. The fossils, called Omo I and Omo II, were found in 1967 at Kibish, near Ethiopia's Omo River, by the famed fossil-hunter Richard Leakey. Although Leakey realized that Omo I, at least, was a H. sapiens, the dating of mollusc shells found with the bones suggested that the specimens were only 130,000 years old. "In 1967, dating techniques weren't what they are now," says John Fleagle of Stony Brook University, New York, who took part in the latest analysis, published in Nature1. And besides, Leakey and his colleagues were more concerned with hunting for something millions of years older. "The fact of the matter is, they wanted early hominids; modern humans were like chump change," Fleagle says.
Human history is AT LEAST 195,000 years old, and 95% of it unrecorded. [ 17 February 2005: Message edited by: JimmyBrogan ]

Oh, fine, where did I put my archaeology hat?The 'mollusc dating' was probably C14 dating, which can be a bit dodgy when conducted on mollusc shells, particularly if they're marine molluscs as the uptake of C14 by sea creatures is different largely because the proportion of C14 in the sea doesn't track with the proportion in the atmosphere. Also in 1967 they didn't have particle accelerator mass spectrometry available, so they would have needed a larger sample and a loooong time to pick up enough C14 decays to get an age. The K/Ar dating dates volcanic deposits and is better suited for the age ranges we're dealing with here (half life in the millions of years instead of about 5500 years). But, it doesn't directly date the living material, just the rocks below where they found the skulls. So you have to infer how long it took for the overlying deposits to accumulate. My question is this: why haven't they tried to date the skulls directly? I'm guessing they don't want to remove even the little bit of material they'd need for C14 dating as this would represent unjustifiable damage to the (priceless) fossils. In all, it's very interesting stuff. Unfortunatley this sort of 'we've got the oldest human' business rapidly becomes politicized, with various countries trying to outdo each other, as if by looking harder and harder you'll suddenly cause the oldest fossil to magically appear within your geopolitical borders. That's (basically) how Piltdown Man got started.

quote: Yes, so it would seem we were walking around with this rediculously gigantic brain for 185,000 years or so, with precious little artifacts to show for it.
There may be a reason for that. Couple of reasons. The tools they had were made of organic materials, which tend to revert back to their natural form. And nomadic peoples don't carry a lot of luggage: they use what's available and leave most of it behind. So their stuff is scattered all over the landscape. Mostly, we find tools and weapons that have been buried with the dead... and that won't happen until they invent a religion which features an afterlife - that requires fairly sophisticated imagination. The big brain can be used to store information about one's surroundings, the invention of language, the detection of danger - a lot of purposes that don't involve hardware. That skull fragment isn't very big. Certainly not enough to reconstruct a face. Where is the rest of him? Where is his family? I would guess this specimen was found a long way from home - possibly carried off by a predator or flash-flood. There should be a lot more someplace in the neighbourhood. I assume archeologists have been digging madly in all directions, without much luck. I haven't seen the other one. Maybe it's a female: Adam and Eve, fleeing the Garden of Eden. No luggage. They meet with a saber-toothed lion, which eats them up and expels the indigestible bits over the next week and 200 miles. The fig-leaves are digestible: gone forever. A&E haven't had a chance to multiply.... God takes a nap of 190,000 years, wakes up, finds a few strands of pubic hair on a bleached lion tooth, clones Cain and Abel and we're back in business. Reconciled. [ 19 February 2005: Message edited by: nonesuch ]

Trying once again to get back on track:Tommy: you're glossing over a lot of hominid/early modern human development with your '185,000 years' line. First: the tool tradition in place at 195000 BP was Acheulian, the famous 'handaxes'. Now, a handaxe, especially a good one, is a tricky thing to make, and there is a sequence of refinement going on within the Acheulian tradition. If you look at handaxes from the beginning of the period, say around 400kBP, they're much cruder and rougher, whereas by 200kBP they're much more refined. As well, as has been noted, there's an complete lack of knowledge regarding any and all types of organic tools being used. For all we know they were weaving linen clothes out of wild flax at 200kBP--the evidence just won't survive except in the most rarest of circumstances. By 200kBP, H.s.Neanderthalensis and Sapiens are now both known, Neanderthals primarily in Europe and adapated for the colder climate, Sapiens in Africa. Handaxes continue to be made, but the Levallois technique is developed about the same time, leading to stone flake tools appearing for the first time. This represent a much more efficient use of flakable stone resources than handaxes, producing much more length of usable edge. This Levallois technique was further refined into the Disk-core technique, which is very similar, but with greater core preparation producing a further increase in efficiency and economy of materials. Note that even at this stage, evolution is still playing a certain role in human origins and development, as the more gracile Sapiens from Africa eventually replace the more robust Neanderthals who developed from H.Heidelbergensis primarily in glaciated Europe. Mousterian technologies persist from 200kBP to the end of the Middle Palaeolithic, about 40kBP. While MP technology is most associated with Neanderthals, this is mainly due to 1) most research initially being conducted in Europe and 2) a glossing over of the fact that early Sapiens were also using Levallois/Mousterian technologies. By 40kBP the Neanderthals are gone from Europe, an the population is entirely Sapiens. At this point we see a blossoming of technological improvements, which fuels the debate about how 'smart' Neanderthals really were: if they had brains as big as ours, why didn't they use them to invent better tools? I won't get into that one here. The Upper Palaeolithic lasts from 40kBP to about 15kBP (note that we still haven't reached your 10,000 cutoff point!). During this period a series of technologies rise and fall, partly for functional reasons, but now we also start to see more artistic and stylistic changes in tools. Solutrean points, for example, are sometimes made so large and so thin that they would be useless as hunting weapons--perhaps they were traded, or used as ritual objects. The UP tool traditions are Aurignacian (very similar to Mousterian), Gravettian, Perigordian, Solutrean, and Magdalenian. With Magdalenian, we find microliths being produced: tiny flakes and blades that can be used as part of composite tools, meaning that a broken point now can be easily repaired by replacing the broken bladelet, instead of making an entirely new point. At 15kBP the ice age is in terminal decline, the forests are recolonizing the landscape of Europe, bringing with them a multitude of smaller animals. The old, big, heavy weapons needed to bring down an aurochs or a mammoth are no longer suited for hunting fox or fowl, or spearing fish. We now see the flowering of both the microlith technologies, and a further increase in the variety and complexity of the archaeological record through to the advent of the Neolithic, whose timing varies from place to place (as does that of the Mesolithic--technically most pre-contact First Nations were using Mesolithic technologies, *technically*). So there's a series of 'burgeonings', times when technology took a step forwards, throughout your 185,000 year period. Taken as a whole, they represent the transition of hominids from evolutionarily-determined creatures to culturally-determined ones, adapting at a rate far faster than evolution ever could. At a certain level, there is a 'laziness' factor in evolution: if an adaptation is working, and working well, it won't change dramatically. H.heidelbergensis was well-adapted to a warm subtropical pre-Ice Age Europe. When the climate changed, they evolved into Neanderthals, still big (for a hominid), still strong, but shorter and squatter and better at making stone tools and planning a hunting expedition. At the same time, early Sapiens in Africa were developing along other lines, more gracile, perhaps slightly more dependent on technology although that's a *very* contestable point, and once they and Neanderthalensis were living in the same regions, Sapiens had the edge. If it had been the other way around, we'd probably look similar to what we look like now, if slightly bigger-boned, but we'd talk about how the disappeared 'Sapiens' hadn't been able to deal with the climate in Ice Age Europe. Remember: evolution doesn't have a target in mind, just a harsh elimination of those that aren't fit enough. (Oh, and that cylinder seal of Fidel's is a fake on stylistic grounds.)

"Tommy: you're glossing over a lot of hominid/early modern human development with your '185,000 years' line."Yes, deliberately so. It would seem to me that what we call civilization is the result of people being moved from what was once savannah into river valley refuges due to desertification of Northern Africa and the Middle East. At some point, some kind of critical mass of human brain power is reached, and we start building cities, technology takes off, etc. At least that was the conventional thinking, based on the Nile and Tigris-Euphrates models. But it seems to me the Chinese, Mayans, Aztecs and Incas didn't need environmental change to transition from hunter gatherers to civilization. Was it farming and the production of surplus food that is the driving force? Maybe, but it seems a long time in the nomadic existance for this to happen. I'm not invoking Fidelian explanations here, just wondering if I'm missing some other factor?

I'm aware of some of Richard Leakey Junior's views and am somewhat interested in archaeology. I believe we all come from Africa. That's looking to me like the best explanation as to why we're here. I think our ancestors were quite dark of skin and had very curly hair!. ha ha I don't need "converting." I am simply commenting. That's allowed in this religion, isn't it ?. If not, then I'll have to find another temple to be called a heretic by its followers.But inbetween the discoveries of partial skull fragments and the odd femur bone of a hairy relative, the story is far from complete I think. Why would Egyptologists get their underwear in knots over someone trying to explain weathering patterns on the Sphynx when they know that none of them has attempted to do so before ?. It doesn't fit with their own neatly pre-packaged assumptions on Egypt. So what?. Why the attempts in haste to provide alternate theories for the erosion ?. And do they really expect us to believe that the out of proportion Pharoahs head belongs on the lions body ?. C'mon!. I mean, they don't really know what the "helicopter" and other glyphs mean at the Abydos tomb, but they can still explain it, surely. I've grown up in an area just south of the Canadian Shield and an area that's home to some of the oldest rock formations in the world. And if you'd been paying attention to another thread, you'd notice that I am quite proud of our native culture in Canada, a people who are quietly suffering through some of the worst indigenous health statistics in the developed world. But for too many Canadians, interest in what are descendants of this continents oldest cultures seems to go for a big shit when discussing their current condition.

Fidel, do you know that bickering, arguing, refuting and contesting evidence is an integral part of how science works? People often have this idea of eggheads in lab coats dispassionately talking about science. That's not how it works... If someone arrives with something new that doesn't please other scientists, it will be hotly contested, sometimes in very emotional terms. And it should be! And it's up to the scientist making the claim to provide the supporting evidence, which will be closely examined and discussed. If the evidence is sound and the idea can be corroborated by more evidence, it will eventually win. It might take a long time though. The process of scrutiny in science works a bit like natural selection: if an idea (and the evidence) can survive its critics, and if it "jives" with other known things, there's a good chance that it is close to the truth. When you post in babble, you often allude to theories and ideas that either don't have a shred of indisputable evidence supporting them, or that have been completely discredited... Things that are closely associated with pseudo-science and quacks on the fringe of science... And you know it too! "Extraordinary claims demand extraordinary evidence."

Absolutely! We don't find large caches of tools and weapons until people have settled permanently. That's when they begin building structures meant to last more than a season and storage facilities and pallisades to defend their property against other tribes. That's also when technology begins to take off in a big way. And, incidentally, when continuity of rulership, land-rights, inheritence, law and religion become major issues. (Otherwise known as The Fall)As aRoused pointed out, this didn't happen all of a sudden. A group of migrant people maybe found a hospitable place, stayed a while, then the weather turned bad or the game ran out, and they moved on. You don't give up a relatively carefree nomadic existence unless you have to. You don't adopt drudgery and serfhood until you have to. And it takes quite a long time before you learn to consider these things the norm. quote: But it seems to me the Chinese, Mayans, Aztecs and Incas didn't need environmental change to transition from hunter gatherers to civilization.
I'm not up to speed on this, but how about: these people were already settled and civilized in some other region before they migrated (perhaps pushed out by a superior military force?) to where we find them today?Fidel: quote: What's this?

There are some San Bushmen, some Northwest Coast First Nations, some Maasai and some Lapps that would like to speak to you about what constitutes 'civilization'. Most incipient state societies began around river systems. Remember that the Maya, Inca and Aztec were all secondary states following on from the Olmecs and Toltecs and such. The early Chinese and Indus Valley (hint..) states also began around river valleys. But sedentism isn't always linked to more complex forms of social organization. We've now found permanent structures dating back to the Mesolithic, and of course there's many examples of modern-day sedentism within gatherer-hunter or horticulturalist economic bases. But why this obsession with state society, glossing all previous forms of social organization? Some of our direct ancestors as Euro-Canadians (I'm playing the odds on you here, Tommy) were semi-nomadic up until the early Middle Ages. Were they 'uncivilized'? I hope you don't think so: some of those semi-nomads brought the word 'law' into the English language.. nonesuch has it right: it's much harder work to live in a sedentary horticultural or agricultural community than it is to be a hunter-gatherer. Also, you tend to be sick a lot more often and die a lot sooner. It's hard work getting in the harvest every year and hoping it lasts the winter! Our meat- and milk-eating Germanic and Scandinavian ancestors looked like giants to the stumpy grain-fed Romans, and that was comparing them to the legionaries! At the same time, sedentism means you're no longer limited to having one child every five years or so, because you don't have to carry them around as you follow the group. Just as evolution doesn't stop, so it's incorrect to describe a chimpanzee as our 'ancestor', because chimps have continued to evolve after our _common_ ancestors diverged evolutionarily, it's also incorrect to speak in terms of 'more civilized' or 'more developed' forms of human social organization. Every society develops along its own path, responding to changes around it both environmental and social. Some exchanged relatively easy lives for harder lives with greater population density, is all. Your formulation makes it sound like some people 'progressed' and others didn't. Whew, this is fun, I haven't thought about early complex societies and state formation processes in *years*!

A theory on the demise of Mayan culture is that it was the consequences of making of endless supplies of lime. They used lime extensively in temples and buildings, and Mayan's burned acres and acres of forest to make relatively little lime. Agricultural yields diminished, and so the gods demanded more more work, higher pyramids and more wars with other tribes for resources. Agrarian collapse was the result of overspending natures capital. It must have dawned on them at some point that working for the gods and their incompetent mortal leaders was a losing proposition. Revolt ?. Ronald Wright says that almost all societies that have existed to concentrate wealth and power at the top of a pyramidal hierarchy have collapsed because of this. Easter Island was a closed experiment in greed that ended in disaster. The Roman's were as unstable during their peak. The costs of empire outgrew resources as well. In Rome, debasement of the currency took place. Citizens worn down by inflation and unfair taxation began defecting to the Goths. Roman soldiers, once considered affluent and respected by the people, became little more than bribed hirelings of the barbarians. Something I read said slaves did the most damage to Rome in the end. The Mongol's were chased out of China for practicing elitism. A peasant rebellion ended the Kahn's mini-dynasty.

Ya, Wright believes that globalisation today will be a scaled-up experiment of past failures throughout history. One thing he doesn't mention is that this may also true of more recent history, the 1929 stock market crash when capitalism teetered on the brink. Keynesianism, or socialism-lite, has shaped several important world economies since. Socialism, from what I know, is closer to the tribal communalism that existed for millenia after millenia and made a return at the end of Rome, an empire dedicated to excess and built on slavery. Turn of the 20th century guilded age industrialism saw riots for living wages in places like NYC, and protestors were shot in the streets by federal troops. The czar also ordered hungry protestors shot at the palace gates. It wasn't a natural economy and increasingly difficult to enforce.More recently, the approximately 30 year experiment in Smithian laissez-faire capitalism focused on individualism to extremes was rejected throughout the western world in the 1930's. Pyramidal individualism has been a relatively hard sell for what have been some of the richest people in world history in our own modern times. Indigenous people in Bolivia and all over Latin America are rejecting globalism and resisting seizure of their countries natural wealth by marauding capitalists. Exclusive property rights are as unnatural now as they were to native North American's when European's arrived and simply moved into their villages. Native people have always known that the earth is what sustains us, not worship of false economic gods. [ 21 February 2005: Message edited by: Fidel ]

I read something once about a period when the oceans were teeming with plankton and shrimp. Large shrimp and other edible sea food that were plentiful over a long period of time. I think the theory says that some of us located on coastal shorelines, and because the marine life was plentiful, we ate hardy and grew bigger brains in part because of the spare time on our hands. Neanderthals, on the other hand, had high caloric requirements to maintain their more muscular frames and would have spent more time looking for food which may have become scarce at some point for them. Does that sound feasible ?.

Interesting.First off, I know there's a difference between "civilization" and "civil behavior". For the purpose of this discussion, I was skipping over that. It seems another topic altogether, where my opinions would not differ much from you guys, I think. Second off, yes my ancestory is European. As far as I can tell it's pretty much a hodge podge. My mother was a war bride from Reddish, near Stockport, and not so far from Manchester, the Venice of the North. (guffaw) And my father's family was from the south. He had straight black hair and a bit of a hump on his nose, features normally associated with Italians. In fact, when on a sight seeing tour with the 1st RCR's in Sicily and Italy, the natives of that country thought he was one of their own. He was told, as a youngster that he had "Norman" features. One Great Grandmother was Acadian. On me mom's side there's some Irish. And that's just going by living memory. If people like my ancestors, with this mix-- real or imagined-- could consider themselves ethnically "English" I see no discernable rule that prohibits me from considering myself ethnically "Canadian". So I do. Anyway..... It occurred to me while reading both aRoused and Nonesuch's posts that maybe the real factor for "civilization" (yes, I'm rolling my eyes) is isolation. I think our nomadic and semi nomadic forebears probably noticed that their garbage dumps became little fields where errant seeds took root. I can't believe it took us 100,000 years or more to stumble upon agriculture. It struck me that the common factor between all these ancient...groups of politically associated people who may or may not have acted civily toward each other... existed in isolation for some period of time. These river valleys in Asia and the Middle East were isolated not just by desertification, but also from other geographical reasons. In the new world, mountain ranges seem to have played the roll that the deserts played in the Middle East. And China has it's deserts and mountain ranges too that would have protected people in the Yangtze and Yallew valleys (sp) from mauraders. For a time. Maybe what civilization needed was to be left alone for a bit to catch on.

I can't quite see bigness as superiority or even privilege. Size isn't just a question of nourishment: there are other adaptive factors at work. In Africa alone, you find Watusi and Bushmen - some of the tallest and shortest people in the world (?? i'm just guessing - don't yell at me!) - both fit, viable and suited to their respective environments.'Progress' is an even more problematic concept. Once a process has begun, it moves along a certain path to some kind of conclusion. Every step along that path is progress. That's no proof that the path itself isn't an evolutionary blind alley, or a colossal mistake. Every group considers itself the norm or model of group behaviour and organization. In an aggressive species, the group that's won the most battles, wiped out or enslaved the most other groups, sees itself as the most advanced. We're tempted to think: "This is the top. I am what evolution had in mind all along." But evolution has a longer view and no predetermined goal. We can be a blind alley, an intermediate step, an accident, and experiment, or the best thing since corn... nobody knows for sure. I saw a tv program today on native North American technology. And modern, European technology-based scientists learning about it. Civilization meets a whole other kind of civilization with respect. Pretty cool.

quote: I think our nomadic and semi nomadic forebears probably noticed that their garbage dumps became little fields where errant seeds took root. I can't believe it took us 100,000 years or more to stumble upon agriculture.
Very likely true. But, as has been pointed out, agriculture is harder work than hunting and gathering, and tends to make you less flexible in coping with minor environmental fluctuations because you've put all your eggs in one basket. So knowing a plant could be encouraged to grow and actually devoting some effort to doing that encouraging are two very different things. In raw economic terms you wouldn't rationally do something that reduces your adaptability and increases your energy outlay versus energy production unless you absolutely had to. Most likely agriculture developed in regions which were circumscribed in some way (as you suggested, Tommy) so that the option to move on isn't as available. Under those conditions, if population grows (not guaranteed to happen) so that the hunter gatherer adaptation is being strained, you might experiment with encouraging the growth of some of the grass species you rely on for part of your food for the year. If the processes of circumscription and population growth continue, you might find yourself devoting more and more time to encouraging grass growth while dropping some of the less efficient other foods, or foods which conflict with grass 'encouraging' time. Eventually over the course of generations the population shifts from full-spectrum foragers to focusing on a single or small group of resources, and you've got semi-sedentary horticulturalists or agriculturalists. This is a sort of optimum foraging (ie, coldly rationally economic) model. Other interpretations exist. For example, increased sedentism and investment in immobile resources (olive groves, manured fields, etc.) makes it harder to just pull up stakes and move away from unpleasant neighbours. Under those conditions, local elites could emerge and bully people into intensifying production and producing surplus food that they can monopolize for their social aggrandizing purposes. That's more of a social model for agriculture and increased sedentism.

"Me mum was a war bride, too, from Sheffield. So have you got Celtic or Saxon feet, Tommy Paine ?. "I didn't know there was a difference. I did notice that a whole lot of people in Northern Wales had the same general physical build as I do, and the same texture hair. I think my maternal Grandfather's family came from Chester, on the Welsh border, so I often fancy there's a lot of Celt in me. Although, I do tend not to lose sight of the big picture, the central goal and not engage in petty infighting within whatever group/organization I'm in, so maybe there's not much Celt in me at all. (wink) Saxon or Celt, all I know is buying work boots to accomodate my ever widening feet is becoming difficult. Oh, I should make this somehow relevant..... I make a big deal about people moving around so much that there's really no point in identifying too strongly with one ethnicity or another. But there was a case a few years ago, where a very old skeleton was found in a cave near a village in England. I think the remains were ten thousand years old or so. Anyway, some scientists were able to extract some DNA from a tooth, and on a lark they got samples and compared it to the DNA of people currently living in the near by village. They found a match with, of all people, the school history teacher. Subjectiveness of the word "civilization" and "progress" aside, I think the History teacher had a warmer place to go to the bathroom than what his ancestor had. That's gotta count big time.

It would seem I have a Celtic foot.Since I'm about to identify with this group, who are all the people I should currently be hating? ---------- An Englishman walks into a pub in Glasgow and orders a beer. Instead of a beer, the barkeep sucker punches the Englishman, knocking him to the floor. Shaking off the shock, the Englishman gets up and says "What the hell was that for!!??" "The Battle of Culloden", the barkeeper exclaims. "The Battle of Culloden!!?? that was over two hundred and fifty years ago!" "Aye," says the barkeep, "But I just heard about it last week."

ha ha Good one. I'm not sure, just that I read where archaeologists in England have found that skeletal remains generally fall into two main categories: Celtic and Saxon. They found that true Celtic feet were narrow and had squared-off toes or straight across at the end from big'un to lil'un. The Saxon's feet were typically broad with downward sweep from large to small toe. Predominantly saxon feet on the Yorkie side of my family. My feet are halfandhalf, but would fit in with those relatives if only for appearance sake. Londoner's and Canadians wouldn't know what the 'eck they were sayin tho. I'll have salt'n vinegar with a few scraps on mine, please.

So is the why no one can yet tell me why I often have a sore back?! Actually, I remember reading several years ago that the remains of a humanoid (they called it a "homanid") were found in Ethiopia that were estimated to be over four million years old. It was supposedly a female, which scientists named Lucy, who they figured walked with a hunched back. THat might explain why I have a sore back.

Uh-huh. Should a figered some silver-tongue devil like yew would make that suggestion. A bit of advise: never tell a redneck that he's got a "heavy tummy." Use the term "beer gut." It's safer. And, nope, I ain't got one, although I sadly admit I'm a few pounds over what I should be.
