Sequencing the Denisovan genome

Posted 1 September 2012 by

There has been a good deal of publicity recently about the sequencing of the Denisovan genome by Svante Pääbo's group at the Max Plank Institute (see here and here for examples). Using brand new technology for sequencing single strands of DNA (single strands as opposed to the normal double-strand), the group was able to achieve a sequencing rate of 30x--every position in the genome was sequenced 30 times. That's comparable to sequencing modern genomes. While some of the coverage has focused on what can be inferred about the individual from whom the DNA was recovered (female, dark skin, brown eyes and hair) what is much more interesting are the relationships of the Denisovans to various modern human populations and to Neandertals. Also interesting is the identification of genetic changes that have occurred in modern humans, a number of the changes having to do with genes associated with brain function and nervous system development, Since John Hawks has discussed the paper in some detail, I won't, but will direct you to Hawks' review of the research. One quotation from that piece--the final sentence--is worth repeating:
Evolution really is the fundamental principle of biology, but using evolution to learn about biology sometimes requires traveling through time. Ancient DNA gives us a time machine bringing new insights into reach.

No Ken, I wasn't there and neither were you. But I can sequence DNA that was there. I can draw valid inferences from this data. You really ought to try it some time Ken. By the way, you can do the same thing with fossils.

The news about this sequencing and some of the conclusions drawn from it has proven to be a lot of fun and extremely interesting even to a layman like me. Technology and techniques are advancing so quickly that important findings are cropping up at a remarkable pace. We didn't even suspect that there were Denisovans until about 2008, and we didn't have good gene-based estimates for Neanderthal introgression until a short while later, and now we're comparing all these genomes with the promise of even more interesting findings to come. That's not to mention the findings of the dwarf Homo population of Flores, or the new Australopithecus finds like A. sediba. This has certainly been an exciting decade for the study of human origins.

I am amazed that Svante Paabo and his team were able to sequence the entire genome from that bone fragment. This is indeed - no pun intended - a stellar achievement. It's also important since it has demonstrated that our understanding of hominid phylogeny is far more complicated than we had suspected.

Loren Amacher · 2 September 2012

As more genetic information accumulates relating to our ancient antecedents, it seems that there is, in fact, something to the multiregional hypothesis, at least for genetic content for many modern humans. We still are, all of us, African in most part. Travelling to Asia, 80,000 ya, carried different opportunities than it does today!

What gets me is that these were people. We know a fair amount of culture going back about 10k years but we know nothing about these guys. In the intervening 30k years think how many Gods were created and disappeared. How many stories of Heros real and imaginary have been lost to us. Were there any empires that we know nothing about over this time.

These are fascinating insights, MichaelJ, which I didn't thought of. They're very good points, though I might add that empires don't appear until thousands of years after we started farming in the Neolithic Period.

Oh yeah? How about the Hyborian Age and the Acheron Empire? We know way more about it than we do about "Eden" or "the land of Nod"!

Now this is really interesting: the Denisovans have the same chromosome 2 fusion as H. saps. John Hawks discusses it briefly here. Assuming that Neandertals also have the fusion (which we do not yet know), that pushes the date of the fusion back before the differentiation of H. saps, Neandertals, and Denisovans.

From a non-anthropology perspective, a question. These are clearly distinguishable populations, but they were human, interbred quite freely with humans to produce fertile offspring, and are partly ancestral to modern human populations. How strong is the justification for designating different species? This is a sincere question; any informed replies will be appreciated.

tomh · 3 September 2012

harold said: How strong is the justification for designating different species?
Svante Paabo clearly considers all three variations the same species. [About Denisovians] "I would not call it a different species, but clearly different groups with a different history. I would not call the Neanderthals a different species from humans either, actually."

Robert Byers · 3 September 2012

its not the next best thing to being there.
Yes its about looking back in time to things not now that way.
All this genetic stuff still requires a constant state of motion on genetic change.
Yet is the physics of DNA settled?
I say it isn't.
The bible says people lived , even after the flood , for hundreds of years.
So our genetics must of been more powerful. Likewise in all biology.
So YEC creationists already can't be persuaded that Dna is a trail for biological relationships.
Whether diversity of time.
All ideas on genetics is founded on a constant state.
There is no reason to rule out other options about flexibility of genetic change.
Evolutionists make a flaw of logic when saying genetic conclusions about biology can not be questioned on the great assumption of constant motion.
Its not been included in these models the option for undiscovered flexibility of genetic change without ideas from evolution.
It must include this option to be a tested hypothesis.
Another whoops for evolutionary biology.

Just Bob · 3 September 2012

Robert,

I won't even attempt to argue with your statements above. They speak for themselves.

But let me help you with a couple of things that maybe you could learn to correct, if you pay attention and are careful (I taught high school English).

Start your sentences with capital letters.

It's not 'must of', it's 'must HAVE'. 'Must of' doesn't even make sense.

When 'its' means 'it is', it always MUST have an apostrophe: it's. You did it wrong three times in that short paragraph.

Avoiding some of those childish errors (and there are many more) won't help your argument, but it will make readers less likely to dismiss your entry, after the first sentence, as the writing of a 5th grader.

DS · 3 September 2012

Still spelling DNA with only one capital eh Robert? Well then, I guess everyone can see what an expert you are when you claim that the physics of Dna is not settled!! Perhaps you can enlighten us about exactly what is is you feel is still in question. Is it the mechanism of mutations? Is it the mutation rate? Is it the randomness of mutations?

Exactly how do you explain this evidence Robert? How can it possibly be reconciled with a young earth and immutable species? You make a flaw of logic when you say that others have ruled out undiscovered things. Exactly what undiscovered things should be considered? Why should they be considered if they haven't been discovered yet? Could it be that you will just reject any conclusion that doesn't agree with your preconceptions?

Dave Luckett · 3 September 2012

"So our genetics must have been more powerful."

More powerful than what? A lawnmower? A speeding locomotive? A Saturn V rocket?

Enquiring minds want to know, Robert. Not your mind, of course.

Robert Byers said: The bible says people lived , even after the flood , for hundreds of years.
Well, Robert, that should be easy enough to establish. Presumably, humans in the age of Methuselah grew to adulthood at the same rate (the Bible is full of old Jewish rituals and rules and the appropriate ages where these things apply, so we can make surmise that growth thru puberty into adulthood was about the same as it is today) Since cranial sutures ossify at a known rate, we can identify the skulls (and dentition) of, say, a 10 year old as opposed to a 15 year old as opposed to a 20 year old. And we know, roughly, what these people ate, and there are probably even modern populations with similar diets (though probably less gritty, because of better ways to grind grain) . A little dento-archeology should quickly be able to compare and contrast teeth of known ages and establish a pretty good ruler for average wear rates. it should be trivial to find and identify old jaws with 200 years of wear. Especially in an arid region like the Middle East, where bodies last a looooong time. It's also noteworthy that this region has been a hunting ground for Biblically-motivated archeology for centuries. So... um.... where are all the really old skulls? [crickets] Indeed, Bob, people have actually done this sort of research, and guess what? People died young back in the day. At 33 Jesus was verging on being an old man in his population when the Romans nailed him to a tree. Life expectancy in the Bronze age and early iron age? 26 years. Though, in fairness, that is skewed a bit by an enormous infant mortality. If you were lucky enough to live through puberty you had decent odds of seeing your early 30's.

From a strictly Darwinian perspective, I've always wondered what modern medicine will do to the human race in an evolutionary sense. In the day, the people who "were lucky enough to live through puberty" were the ones who had lived long enough to breed. By that winnowing process, they were the hardy ones, the tough ones, the ones that the TOE would predict would pass on their genes to their offspring. Today? Not so much. I would have died from stomach ulcers before my 15th birthday. Without orthodontia, my teeth, and those of my son would have seriously compromised our ability to eat. Our son wouldn't even have been born without IVF. Yet here we are today, healthy contributing members of society. But our genes? Not so much, or at least not as much as 2,000 years ago. It's looking like collective intelligence and technology is going to practically nullify the effects of "natural selection" on the human phenotype. Oh, to come back in several thousand years, to live to see what the seeds we sew today have wrought! :-)

We are just selecting for different things now, such as the ability to correctly judge the speed of an approaching vehicle. Our technology has changed the environment, but evolution is still tracking the changes.

Infant and childhood mortality were the real skews on the population statistics. A settled farming population with access to a good diet may live out what we would regard as a "normal" lifespan, with some respectable proportion of those who reach adulthood reaching sixty or seventy. Old people are repositories of knowledge in preliterate societies, and valuable for that reason, and so are usually supported past their ability to contribute with labour. At the same time, settlement removes the necessity for keeping up with the group as it forages. Hence the Biblical description of human life expectancy: "three score years and ten".

The difficulty arises with intensive cultivation of grain. Given suitable land, cereal crops return the greatest number of calories per area, albeit at the cost of constant grinding labour. Land is converted to cereal farming by ploughing, drainage, ditching, irrigation and terracing. Woodland, wetland and hill pasture, sources of other foods, are reduced. Malnutrition appears as grain replaces them. At the same time, repetition and overuse injuries appear and become severe. So do dental caries.

All this tends to shorten life, except among the elite. But an elite is also a characteristic of settled agrarian populations.

Ian Derthal · 4 September 2012

The problem I suppose is one of biblical inerrency. If the bible says early humans had life spans of 900 plus years then they did, even if there is no fossil evidence for this scanario.

No matter how silly the claim, if the bible says it then Robert believes it.

It's as simple as that.

TomS · 4 September 2012

Nearly everyone qualifies their belief in the primacy of the Bible. Very few people go along with Biblical heliocentrism, for example, even though for something like 2000 years it was the universal belief that the Sun orbited a fixed Earth, and agreed that the Bible said so. Most people today believe that the Earth is a planet of the Sun on the basis of modern science. (Even though few of them are able to give good reasons for that belief.) This is only one of the more striking examples of how people will qualify their trust in the Bible. (I dare say that the evidence for evolution is more accessible than the evidence for geocentrism.)

Dave Luckett · 4 September 2012

I'd agree with TomS. Even the godbots we get here don't actually believe in Biblical inerrancy, not really. They say they do, of course, but any time the Bible doesn't actually say what they want it to, they indulge in a little quiet metaphorisation, and hey presto!

And yes, to observe the retrograde motion of Venus and Mercury takes some doing, and a tremendous piece of insight to see how it is better explained by the Earth in motion rather than that it's them doing loop-the-loops.

The impact of modern medicine on human selection is much less strong than you may think. To some degree, it has an indirect effect, as the human traits being selected for right now are any alleles, if such exist, that are associated with extreme poverty, inadequate access to health care, and high childhood mortality. Those are the people with the "reproductive advantage" in today's world. Those are the people who live in places where there is a strong net population growth. Many of what we perceive as common "genetic" problems are environmental. For example, no pre-literate population ever has myopia to any significant degree. Myopia is common in all literate societies. Clearly, the alleles are there (possibly selected for in humans for some other reason or linked to something that was selected for), but the negative trait is only expressed in literate societies. A myopic hunter gatherer might be in trouble, but they don't get myopia, because they aren't exposed to the environmental risk factor. It's much the same with many, many dental problems, not just caries. Many premature deaths in the past were due to pathogens so virulent that any human has a good chance of dying from them, on first exposure, if untreated. Random chance plays a large role in populations with high exposure to virulent pathogens, and lack of adequate medical care. Now, obviously, Eurasian populations of early modern times did have a relative resistance to Eurasian infectious disease, relative to Amerindian populations that is, for example, so there are long term trends, but such things may be more subtle than people think.

You are correct. It's called relaxed selection and there is no doubt that modern technology is responsible far a substantial increase in the frequency of many deleterious alleles in the human gene pool. This can be quantified by estimating the number of lethal equivalents in the human genome, which are increasing due to modern technology. But there are two things to remember about this effect. One is that as long as we retain modern technology, it may be OK to maintain a lot of this hidden variation. After all, alleles are only deleterious in a given environment. It may even prove to be beneficial if the environment changes in unexpected ways. Second, just because selection is relaxed for many traits, doesn't mean that it doesn't still operate for others. Currently, we seem to be under strong selection for genetic variation with regards to susceptibility to pandemics, resistance to side effects of pharmaceuticals, and resistance to the toxic effects of pollution. The fact that we have chosen to inflict these selection pressure on ourselves doesn't make them any less real. The interesting thing about ancient DNA analysis is that it can reveal evidence of selective sweeps in parts of the ancient human genome. This can help to determine the most important selection pressures in the past and can be used to predict possible responses to modern environmental challenges. So once again, modern evolutionary theory is central to studies of human health and planning for the future of the human race and creationism is till a nonstarter.

My dental problems were the result of large teeth (dad's) in a small jaw (mom's). I wonder if that kind of variation would exist in small local populations or if that, too, is a result of our increased mobility since... well, since the wheel, I guess.

You make a interesting point here that YEC would jump on. If people lived that long, they did into the hundreds, then their biology allowing this would also stop decay. It would not be the usual rates of decay that they today judge skeletons by. Therefore , possibly found, a old skeleton would be hundreds of years old but only have the decay of decades old. They can only tell age in a skeleton by modern decay rates. Better rates inb the past would hide the error. This is my point about DNA . it is entirely based on assumptions of cionstant change being only what is thought to happen today. A error of investigation even if they were right. Lack of imagination for bigger options of flexibility. By the way its a myth people didn't live long back in the day. the bible says man is given 70 years/80 with health. Even if you don't believe its the word of god it must of been a common observation for any audience. Confusicious (sp) said 70 too and Herodotus said likewise. if it was lower it must of been a degraded society. Anyways nobody was keeping score for modern accurate analysis.

He may be in the minority, tomh. I think most hominid paleobiologists and physical anthropologists would regard Neanderthals as a separate species, which split off from the populations that became Homo sapiens approximately 800,000 years ago.

If it's "common" to believe it, how come most people don't? A large majority of the world thinks your bible is wrong and/or irrelevant. And why is it that the people who supposedly do believe the bible, can't agree with one another on what the bible says? And why is it that so many of the people who think the bible is the word of god, and want to hit you over the head with what they believe, don't obey the literal directives of the bible (like you, for instance). And what makes you think the burden is on someone else to prove that your fairy tale is wrong? It's your assertion, you prove it.

You have been shown the evidence Robert. Here it is again: Venema (2010) Genesis and the genome: Genomic evidence for human-ape common ancestry and ancestral Hominid population sizes. Perspectives on Science and CHristian Faith 62(3):166-178. This evidence shows that there were no genetic bottlenecks in recent human history and flatly falsifies the biblical account. Until you can explain this evidence, everyone should just ignore your mindless rantings. There was no magic flood, not one, never was. And by the way, our civilization was founded on the assumption that the Greek gods were real, does that mean you believe in them Robert?

If "decay rates" were different for humans living 4,000-6,000 years ago then there would also have to be marked anatomical and genetic differences in specimens collected from that time period. Anthropologists and Biologists haven't found evidence of any genetic or morphological differnces that account for your proposed "slower rate of decay" either. Also Stevarino pointed out that a dento-archeological analysis should be able to determine ages based on average dental wear. I agree that this would probably be one good method of determining how long people lived on average during the time period in question even if your conjecture were correct. Enamel is formed by the enamel organ of the dental follicle prior to eruption. During tooth eruption the dental follicle and enamel organ completely degenerate. Hence enamel doesn't regenerate once a tooth has erupted. Therefore even if other parts of the body had a slower rate of decay in the past say by ancestral DNA having far more telomeres than it presently has, teeth would still exibit a consistent pattern of wear since enamel doesn't regenerate. But hey, according to you God can use magic to do whatever he wants so that your interpretation of the Bible is correct.

Not decay, Bob. Wear. Read for comprehension. What I said was 1) identify 10, 15 and 20 y/o secondary teeth from this population (because individuals of this age can be identified by cranial suture characteristics. Been done, BTW ). 2) calculate the wear rate on their teeth (been done, BTW). 3) extrapolate that into 30 decades. 4) demonstrate teeth showing 300 years of wear. This methodology requires no magic, nor any (baffling) explanation of why there should or should not be some heretofore unexplained "intelligent cavity" phenomenon. It takes no reliance on dental decay at all, though, frankly, the methodology would work just as well. Although I imagine that in a hunter-gatherer world devoid of processed sugars there were fewer cases of youthful cavities, I suspect that the total lack of effective dental care eventually caught up with people. Heck, my cat hasn't brushed his teeth in 10 years and he has gum problems, and the only bad thing he eats is a few licks of ice cream he occasionally mooches.

How about an intersubjectively replicable method, one that works regardless of prior beliefs. Got one, Marilyn? Temperature is reliably measurable: anyone can use the appropriate physical methods and measure it reliably. Electrons are reliably detectable: anyone can use the appropriate methods and detect them reliably. God, on the other hand, can't be 'detected' without committing to prior assumptions that cannot themselves be tested. That's the difference between warranted knowledge claims and religious beliefs: The former don't depend on special states of mind to operate. For a nice example of a failure to be replicable and the influence of prior beliefs, see the story of N-Rays.

Actually, "civilization", as we know it is probably more dependent on the Egyptians, Babylonians, Romans and Greeks than anything the Christians did. After all, those earlier civilizations did most of the heavy lifting that moved humanity out of mud huts and into cities with niceties like written languages, organized trade and (at least prototypical) democracy. Compared to that, the Christians accomplished relatively little. In fact, you could argue that by obsessively battling the "heathens" via things like the crusades they actually got in the way of civilization by thwarting the progress muslim scholars were making in mathematics and science. It wasn't until the Renaissance, when the grip of the church loosened to the point that you could investigate how stuff worked without being accused of dabbling in the dark arts that western civilization finally shifted out of "park" after 1200 years and started moving forward again. Am I wrong? Give me one important aspect of civilization that would collapse tomorrow if every Bible on earth suddenly flashed out of existence.

I do so love it when fundamentalists quote "literally true" bible verses, which I then take absolutely literally, and watch them squirm to explain that the bible doesn't, you know, literally mean what it literally says. Marilyn, this verse LITERALLY means that the speaker (Jesus, God, Whoever) is not there UNTIL two or three are gathered. If the speaker is always present, everywhere, then there's NO POINT in making the statement that he will be there when 2 or 3 are gathered. It also implies that it REQUIRES 2 or 3 believers to get Jesus there. One apparently isn't enough. And why the equivocating about whether it takes 2 or 3? If 2 are always enough, then why say 2 OR 3? Are 2 sometimes NOT enough (which is what is implied)? What determines whether 2 are enough or 3 are required this time? Strength of their belief? Praying the right words? Holy whim? Are you sure he ALWAYS shows up when "when two or three are gathered [his] name"? Even if they belong to a Christian denomination that you are sure is going to hell?

So if Carbon-14 dating is all just, you know, miscalibrated, why don't Creationists perform their own calibration of C-14 and give us their TRUE ages for all of those C-14 dates?

The Denisova Cave, the Egyptian timbers inside tombs, all that good stuff - why don't they just tell us HOW OLD IT REALLY IS?

I thought they said they were 'scientists'? Can't they do some real, you know, 'science' and recalibrate all those C-14 dates.

And while they're at it, why not give us their 'properly' calibrations for Potassium-Argon dating, Lead-lead dating, Uranium-uranium dating, all those radioactive datings, and DENDROCHRONOLOGY, and VARVES, while they're at it?

What is wrong with these 'scientists', like Michael Oard (meteorology)? They could win a Nobel Prize when they show all those dating methods are wrong.

It may be rather inconvenient that many Christians already accept radiometric dating (link here). It may be inconvenient that at least some of the pioneers in radiometric dating (including C-14 dating) were Christians.

Just Bob · 4 September 2012

And Marilyn, while you're busy ignoring my literal explication of your bible verse, here's something else that I suspect you'll choose not to answer.

What EXACTLY does "gathered in Jesus' name" mean?

If any group declares that it is meeting "in Jesus' name", is it really, or are some groups claiming it but not really doing it? How about the White CHRISTIAN Knights of the Ku Klux Klan? They gather in Jesus' name? Does Jesus attend their rallies? How about the white supremacist Christian Identity churches? The Westboro Baptists when they gather in Jesus' name to tell grieving relatives that their dead children in the US military are going to hell because America doesn't persecute gays nearly enough to satisfy Jesus?

I'm sure that you're sure that Jesus is present for your Sunday services and bible study. But do you think He attends Catholic mass? Russian Orthodox services? Mormon ceremonies? Secret Masonic meetings? A liberal Methodist church that welcomes gays?

And what does Jesus' presence contribute to the affair? Does His presence guarantee that the group always makes correct decisions? Does their behavior noticeably change when He shows up? Can members tell when and if He leaves? Does He manipulate the minds of those present to get them to do what He wants? Does He always get a majority for His way? Why isn't it always unanimous?

Not quite sure what your point is, but a Scientist would only infer the sort of things about Denisovans from their ancient DNA that can be inferred about modern humans from the human genome. That said, I think it reasonable to additionally infer that Denisovans did not believe that a god was going to create a universe for them to live in in about 35,000 years' time.

Marilyn,
RBH's quote should probably be read as 'the genetic relationships between Denisovans, Neanderthals, and modern humans are much more interesting than traits like eye color.'

Now, I admit that I can't be absolutely certain what you mean here, but it certainly seems to me that you are implying that this "God" is pretty obvious and upfront about its existence. Yet in the statement above you seem to be changing your claim, implying that there are some folks who don't get to see this "God" regardless of how thick their skin is. I mean, you clearly have not measured Phhht's skin thickness in any objective way. You may be of the opinion that he's got really thick skin and consequently that's the reason he can't detect this "God" of yours, but really...so what? That's just your opinion and it's of equal value to Phhht's opinion that this "God" of yours in not detectable because it doesn't exist. So let's try a slightly different question: is there a way to detect this "God" of yours without being a Christian? If so, how can such a person detect this "God"?

Based on the recent findings of Neanderthal DNA fragments in the human genome, it would appear that they interbred, at least to some extent. It is my information that two populations that are able to interbreed and produce viable and fertile offspring are considered to belong to the same species. Thus, Homo sapiens sapiens and Homo sapiens neanderthalis.

Now that we know Denisovan had 46 chromosomes, it is implied (though not yet expressed) that they had the distinct human genes PGML/FOXD/CBWD from human chromosome 2.
Therefore the only way those guys received these genes is from the first mating in our ancestry of 46 with 46. Therefore we know that the hominids were hybrids of humans and apes, with Denisovan and Neanderthal the last in that sequence. They were exterminated in the Great Fossilization following Genesis 6:12.

stevaroni said:
Robert Byers said: The bible says people lived , even after the flood , for hundreds of years.
Well, Robert, that should be easy enough to establish. Presumably, humans in the age of Methuselah grew to adulthood at the same rate (the Bible is full of old Jewish rituals and rules and the appropriate ages where these things apply, so we can make surmise that growth thru puberty into adulthood was about the same as it is today) Since cranial sutures ossify at a known rate, we can identify the skulls (and dentition) of, say, a 10 year old as opposed to a 15 year old as opposed to a 20 year old. And we know, roughly, what these people ate, and there are probably even modern populations with similar diets (though probably less gritty, because of better ways to grind grain) . A little dento-archeology should quickly be able to compare and contrast teeth of known ages and establish a pretty good ruler for average wear rates. it should be trivial to find and identify old jaws with 200 years of wear. Especially in an arid region like the Middle East, where bodies last a looooong time. It's also noteworthy that this region has been a hunting ground for Biblically-motivated archeology for centuries. So... um.... where are all the really old skulls? [crickets] Indeed, Bob, people have actually done this sort of research, and guess what? People died young back in the day. At 33 Jesus was verging on being an old man in his population when the Romans nailed him to a tree. Life expectancy in the Bronze age and early iron age? 26 years. Though, in fairness, that is skewed a bit by an enormous infant mortality. If you were lucky enough to live through puberty you had decent odds of seeing your early 30's.
You make a interesting point here that YEC would jump on. If people lived that long, they did into the hundreds, then their biology allowing this would also stop decay. It would not be the usual rates of decay that they today judge skeletons by. Therefore , possibly found, a old skeleton would be hundreds of years old but only have the decay of decades old. They can only tell age in a skeleton by modern decay rates. Better rates inb the past would hide the error. This is my point about DNA . it is entirely based on assumptions of cionstant change being only what is thought to happen today. A error of investigation even if they were right. Lack of imagination for bigger options of flexibility. By the way its a myth people didn't live long back in the day. the bible says man is given 70 years/80 with health. Even if you don't believe its the word of god it must of been a common observation for any audience. Confusicious (sp) said 70 too and Herodotus said likewise. if it was lower it must of been a degraded society. Anyways nobody was keeping score for modern accurate analysis.
If "decay rates" were different for humans living 4,000-6,000 years ago then there would also have to be marked anatomical and genetic differences in specimens collected from that time period. Anthropologists and Biologists haven't found evidence of any genetic or morphological differnces that account for your proposed "slower rate of decay" either. Also Stevarino pointed out that a dento-archeological analysis should be able to determine ages based on average dental wear. I agree that this would probably be one good method of determining how long people lived on average during the time period in question even if your conjecture were correct. Enamel is formed by the enamel organ of the dental follicle prior to eruption. During tooth eruption the dental follicle and enamel organ completely degenerate. Hence enamel doesn't regenerate once a tooth has erupted. Therefore even if other parts of the body had a slower rate of decay in the past say by ancestral DNA having far more telomeres than it presently has, teeth would still exibit a consistent pattern of wear since enamel doesn't regenerate. But hey, according to you God can use magic to do whatever he wants so that your interpretation of the Bible is correct.
First there probably is no skeletons etc remains from the first two centuries after the flood and when biological power was greater indicated by the long lives. I don't see why there would be anatomical differences . Just slower body decay. by the way within this one would included all the DNA change we now have in human beings relative to one another and others like "neanderthals" etc who just did change in these ways . The bible mentions peoples with different body types. I don't know if any teeth of the first folks are around. If one is living hundreds of years then why not the teeth be suitable and not so easy , as ours, to wear away?

Not decay, Bob. Wear. Read for comprehension. What I said was 1) identify 10, 15 and 20 y/o secondary teeth from this population (because individuals of this age can be identified by cranial suture characteristics. Been done, BTW ). 2) calculate the wear rate on their teeth (been done, BTW). 3) extrapolate that into 30 decades. 4) demonstrate teeth showing 300 years of wear. This methodology requires no magic, nor any (baffling) explanation of why there should or should not be some heretofore unexplained "intelligent cavity" phenomenon. It takes no reliance on dental decay at all, though, frankly, the methodology would work just as well. Although I imagine that in a hunter-gatherer world devoid of processed sugars there were fewer cases of youthful cavities, I suspect that the total lack of effective dental care eventually caught up with people. Heck, my cat hasn't brushed his teeth in 10 years and he has gum problems, and the only bad thing he eats is a few licks of ice cream he occasionally mooches.
If they can be identified by cranial points on age then the teeth aren't needed. Once a person reaches maturity, 20 say, they would because of greater biology ability look the same for hundreds of years as the bible says. Teeth wear just another aspect of this.

stevaroni · 6 September 2012

Robert Byers said: First there probably is no skeletons etc remains from the first two centuries after the flood and when biological power was greater indicated by the long lives.

Actually, bodies from this period are plentiful throughout the middle east, a naturally dry area where many cultures had rituals involving carefully interring their bodies. Particularly in Egypt. This being the tail end of the Old Kingdom preserving the dead was all the rage. Although only the very well-connected could afford to get the full mummy-in-a-golden-mask treatent, it was common for individuals of moderate means to be treated with a decent amount of care and laid to rest in desert cemeteries that dessicated their corpses and left giant fields of very good skeletons.

If they can be identified by cranial points on age then the teeth aren’t needed. Once a person reaches maturity, 20 say, they would because of greater biology ability look the same for hundreds of years as the bible says. Teeth wear just another aspect of this.

Still not reading for comprehension, Bob. Permanent teeth start erupting in humans at about 7 years of age. For the first 20 years of life or so you can readily and unambiguously date a skull by cranial sutures. If you've got the skull of a 10 year old, he's been chewing on his first molars for maybe three years. You can thusly identify molars that people have been chewing with for 3 years, 7years, 10 years, 13 years, etc. Given a large sample size, you can determine, within reason a rate of dental wear for that population with that diet. People have done this. They have written very nice papers on it. There's even a name for the subspecialty of people who study this sort of thing "osteologists". If you then look at very old skulls, assuming that all these Methuselahs continued to eat throughout their adult life (a fairly safe assumption) you should be able to find molars that show 300 years of wear. Especially since many of these individuals would have been amassing status, wealth and family position for hundreds of years, and high-status individuals tend, as a class, to be treated relatively well in death, buried carefully rather than, say, being fed to the dogs. The many, many, many generations of religiously motivated "Biblical Archeologists" who have been digging up the holy land for the last 200 years to prove a literal Bible should have a stack of bodies by now. ICR should have a real paper on this - and I mean a real paper, not one of those silly bullet point things they have on their website. This should be trivial, Bob. 300 year-old jaws should be everywhere in the holy land. But... um... they're not. Now I wonder why that might be, Bob?

I want to make sure I understand what you are claiming. You are saying: no human teeth from Noah's era should show more wear than a 20-year-old's. Because the folk who lived to 60, 100, 200, 300 would all have teeth that had the same wear and tear as a modern 20-year-olds. Is that correct? So, if someone found really old human teeth that had the wear and tear of 60 years of use, then that would prove you wrong, correct?

This is what I've been trying to get through his head. Even if post-deluge populations had super-teeth in intelligent anticipation of them having to last 500 years, you should still be able to see this in the wear rate derivable from samples of the younger members of the population. Say a modern molar wears at 1mm/decade when you eat stone-ground grains with lots of grit in them. Say you look at ancient teeth and they only wear at 0.1mm/decade. That still gives you a wear rate. In fact, since the wear rate is so unexpectedly tiny it tells you quite a bit more. frankly, it would probably tell you that you're looking teeth from a modern urban dweller who never has to chew anything more challenging than a Big Mac, but if you were to find lots of them in ancient burials, it would re-write what you thought about ancient diets or ancient teeth. Then, you might even be driven to test the teeth and compare their enamel hardness to baseline teeth to see what the actual deal was. people have done all this. In fact, we know the ancients, as a group, made pretty good enamel. They had simple, mineral-rich diets low in the sugars that cause a lot of dental problems in modern humans. And they chewed a lot, which, within reason, promoted good, solid, bone in the jaws. We also know that their teeth did, in fact, wear fairly quickly, probably as a result of their foods containing a lot of residual grit from the threshing and grinding grains. Finding teeth with little wear is actually exciting for archeologists - it can be an important marker for status, because it means that that individual probably got better food. In short, Bob, there is no magical mystery factor whereby ancient teeth were magically well adapted to 500 year old lives. We know this because we can test it. And people do all the time. Google dental + archeology. You get millions of hits. Read some of them. For comprehension.

Robert Byers said: First there probably is no skeletons etc remains from the first two centuries after the flood and when biological power was greater indicated by the long lives.

Actually, bodies from this period are plentiful throughout the middle east, a naturally dry area where many cultures had rituals involving carefully interring their bodies. Particularly in Egypt. This being the tail end of the Old Kingdom preserving the dead was all the rage. Although only the very well-connected could afford to get the full mummy-in-a-golden-mask treatent, it was common for individuals of moderate means to be treated with a decent amount of care and laid to rest in desert cemeteries that dessicated their corpses and left giant fields of very good skeletons.

If they can be identified by cranial points on age then the teeth aren’t needed. Once a person reaches maturity, 20 say, they would because of greater biology ability look the same for hundreds of years as the bible says. Teeth wear just another aspect of this.

Still not reading for comprehension, Bob. Permanent teeth start erupting in humans at about 7 years of age. For the first 20 years of life or so you can readily and unambiguously date a skull by cranial sutures. If you've got the skull of a 10 year old, he's been chewing on his first molars for maybe three years. You can thusly identify molars that people have been chewing with for 3 years, 7years, 10 years, 13 years, etc. Given a large sample size, you can determine, within reason a rate of dental wear for that population with that diet. People have done this. They have written very nice papers on it. There's even a name for the subspecialty of people who study this sort of thing "osteologists". If you then look at very old skulls, assuming that all these Methuselahs continued to eat throughout their adult life (a fairly safe assumption) you should be able to find molars that show 300 years of wear. Especially since many of these individuals would have been amassing status, wealth and family position for hundreds of years, and high-status individuals tend, as a class, to be treated relatively well in death, buried carefully rather than, say, being fed to the dogs. The many, many, many generations of religiously motivated "Biblical Archeologists" who have been digging up the holy land for the last 200 years to prove a literal Bible should have a stack of bodies by now. ICR should have a real paper on this - and I mean a real paper, not one of those silly bullet point things they have on their website. This should be trivial, Bob. 300 year-old jaws should be everywhere in the holy land. But... um... they're not. Now I wonder why that might be, Bob?
It still comes down to the wear on teeth. If folks, they did, live long lives for a while after the flood I see no reason for them not having great teeth under the principal of superior biological strength. Finding them is not issue as i doubt they would be found. Perhaps the whole issue of replacement of teeth was interfered with. Again strength of teeth being different is as likely as the rest of the body.

The wear would be less because the people are biologically stronger. How this works out in teeth is speculation but is fine for me to see the teeth didn't get worn out like the rates today. I want to make sure I understand what you are claiming. You are saying: no human teeth from Noah's era should show more wear than a 20-year-old's.

Dave Luckett · 7 September 2012

Byers thinks that teeth can be biologically stronger, whatever Byers means by "stronger". Not that 'stronger' has any specific meaning at all in this context.

No, Bob. Wrong again. The teeth of ancient skulls have been minutely examined, and as has been explained patiently to you, those teeth are like ours, not "stronger". Their tooth enamel was the same as ours, and its thickness the same as ours would be, if we ate the same foods as they did. The wear patterns show that people five, six, seven thousand years ago lived shorter, not longer lives than we do.

Them's the facts, Bob. Suck it up.

Furthermore, Robert Byers still has not explained why no one has ever found any skull belonging to one of these legendary Biblical poly-centurions in the first place.

I hate to admit it, but in some ways Byers does me a favor with these senseless arguments of his. When he babbles his nonsense, I often find myself wondering "well, what do we actually know about this? Unlike him, I actually use the search bar on my browser to try to investigate it. This week, like many times before, I've spent hours that I'd otherwise be wasting watching TV in looking up the things that Byers spouts of about - in this case reading paper after paper on forensic dental osteology in the Biblical Holy Lands. Once again, I'm amazed how much excellent information is out there at your fingertips if you only look for it. I compare and contrast this with my undergrad days when researching the simplest question required going to the university library and slogging through publication indexes for hours. Now, you plug a search term like "dental archeology" into PubMed and get hundreds of interesting hits that take me hours to read. But hey - now I know about things like "Dental health in Northern Chile's Atacama oases: evaluating the Middle Horizon (AD 500-1000) impact on local diet." Bob may be a purposely ignorant ass, but he reminds me constantly that we live in marvelous times.

DS · 7 September 2012

Hell he can't even click on the links that are provided for him. His nonsense is completely refuted by even the most trivial facts. He seems to think that if he refuses to look at it, it doesn't exist. Kind of like a three year old playing hide and seek by covering his eyes.

The ice man lived 5300 years ago and died at the age of 40. His teeth were in really bad shape. He was no pre flood super human, that's for sure. Bobby can't explain it. So what? He can't explain any of the evidence from genetics either.

As detectors, our signal to noise is terrible and we appear to be extremely imprecise (our detections are all over the map). This assumes there aren't an infinite number of contradictory gods. If that's the case, then hey, maybe each detection is signal and what looks like imprecision is just individual accurate detection of different entities.
