You can distribute the SNPs on the A and DR line any way you want. 470 for A and 0 for the rest if you like. You've still got a falsification of YEC. All you need to know is that you can find pairs of humans with more than 600 SNPs on 3.2MBp of the "Y", and you're more than 99% sure that the standard YEC model is false.
As for a lot of truth in what you're saying, the problem is that you'll make fundamental mistakes, get an idea in your head (like thinking that they've used the chimp to find the within human variations in the first place, rather than just to determine the ancestral allele after they are found) and then waste lots of time because of those mistakes.
I said the following:
{I feel that so far, you misunderstand the extent to which their use of the chimp to represent the ancestral allele has affected your conclusions. And so far there are just far to many assumptions (one example - how to distribute the variations between A and DR) and too many variables (mutation rates, generations, % chimp that matches humans, division of mutations between DR and A, division of mutations between the 36 and the 1) and too many overestimations (mutation rate, no of mutation being 6271, no. of mutations in "A")}
You replied that I make mistakes, without actually dealing with the many problems that I pointed out with your conclusions. Your 600 SNP's argument is affected by many factors, and to brush off those factors with sweeping statements leaves this discussion at a stalemate. You have to deal with EACH objection in a mature manner to back up your conclusions. Including lifestyle factors, and uncertainties regarding mutation rates, bit arguments which on their own destroy your point.
Firstly, they don't exactly "cut down the number of variations". What the bit you've quoted here means
Haha, they reduced the number from 6662 to 6271 due to the chimp comparison. They did cut down the number of variations, now are you saying they didn't? Ummm well.
quote:
"We extracted the ancestral allele for each position that was variable in humans (assumed to be the allele present in chimpanzee) using the Ensembl-Compara pipeline (Vilella et al. 2009), release 66, and obtained calls for 6271 of the total number of 6662 variable sites (Fig. 1; Supplemental Table S2)."
is that they found 6271 of the 6662 variable sites in the chimp. The chimps are missing the rest. Overall, the chimps are missing about 30% of our "Y", but on that particular 8.97 Mbp, they have nearly all of it. In the 3.2Mbp chart we're looking at, they've left out the SNPs for which they don't have an ancestral match, which is about 5%. The only effect this has is that it makes the "Y" ancestor seem a bit younger than it actually is, which is to the advantage of YEC. Now, here's an example of something you've picked up on, misunderstood, and therefore started to base lots of mistakes on your misunderstanding.
Are you saying that the chimp matched the reference sequence in 6271 positions. The study does not say if the chimp matched the reference sequence, but rather seems to indicate that the chimp's alleles matched the variants (the 36 individuals). Please back up your view from your link, because this needs clarification and without it your evidence is meaningless.
The chimp-ckicken comparison is about structure, not SNPs. Whole chunks of our "Y" are missing from the chimp, and whole chunks of theirs from ours. Plus there are all kinds of rearrangements. But where humans and chimps share chunks of it (as in most of the 8.97Mbp that the paper is dealing with) the nucleotide identity is 98.3% the same. So, while the chimp is not the ideal outgroup for these 36 individuals (Neanderthal would be better if it was well enough sequenced) it's pretty good.
If you and I differed on a given locus on the "Y" that also existed in the chimp, we could be 98.3% sure that the one who also differed from the chimp was the one carrying the mutation. This would apply just as much if the similarity between us and the chimps was due to common design by a creator as it does with common descent, because we can establish the 98.3% reality regardless.
So, you could put their figures of 285 and 185 along the A and DR lines if you wanted to without assuming common descent, but it doesn't really matter what we put there so far as the falsification is concerned.
I'll get on to the stone age people appearing in medieval Europe in my next post, hopefully, because I find it amusing.
BTW, you'll find what you're looking for in the Method section of the paper.
Meet GRCh37
You are focussing on the chimp, a point which you still have to show evidence for. But in addition to the chimp point, there are multiple other problems with your conclusions that you are just not dealing with.

Your perception of "many problems" comes from your mistakes, or from willful misunderstanding, conscious or subconscious. If you understood the information in the paper, you would be at least 99% sure that your young biosphere model is false.
sweeping statement when I asked you to be precise.
Stop decieving yourself! It won't fool people who understand the two papers I'm using.
Another sweeping statement, my concerns are legitimate and listed.
Do you realise that you need the SNP mutation rate to be more than 10 times what was found in the 13 generation pedigree study? No amount of variables can give you anywhere near that.
That's with your interpretation of the study. Just because there are variants between two genomes, does not require that the variants are actual SNPs. No-one knows which genome has the ancestral allele, and which genome has the mutated allele. This principle applies when comparing "A" to the rest, and also when comparing the 36 to the reference sequence. My point is obvious, its accurate, and yet its ignored.
Every time I mention this, you revert back to your "600 variants" argument in individual "A", should I then forget about your original argument, and we base your entire argument on individual "A"? Because you seem to be ignoring that the other 35 individuals have variants, and NOT all those variants are mutations, some of them are original alleles. This is obvious.
Once again, you're showing that you don't understand what you're reading. The chimp doesn't have any alleles for the loci that it doesn't have, to state the obvious. You're also showing that you don't understand why the chimp is irrelevant to our falsification. Do you understand the following? If we want to find out approximately how far two humans are from a common Y ancestor, all we have to do is compare a sizeable section of their Y chromosomes. The chimps can be extinct. If you find two individuals with 600 differences on 3.2Mb, you've falsified the standard YEC model, because no plausible mutation rate can give you that effect. You will find your 600+ by comparing any haplogroup "A" individual with individuals from any other haplogroup.
Oh really. And how many of those 600 differences are mutations, and how many are original alleles? What if they used multiple individuals in the reference sequence, surely that would emphasize the number of differences? Or are we just to assume all parts of the reference sequence have exactly the same perfect proportion of mutations? Surely that's a huge assumption. Kindly focus on this point please. Admit it, Face it. Something.
It had those loci which all the humans had. The rest were deleted in the chimps (or not designed into it, from your point of view). The loci that are non-existent in the chimp still contain mutations which have occurred in the human group since the common Y ancestor (there's more there's one allele present on those loci)
Explain why they dropped the number of variants from 6662 to 6271 using the chimp's loci? If you can explain this clearly, you will then succeed in explaining why the chimp is irrelevant.
Please understand I am just taking the wording at its face value, the wording does not say they "extracted the ancestral loci" , the wording is saying they "extracted the ancestral allele" for the 6271 positions. Doesnt this mean they found the ancestral allele in all these positions, where though? In the reference sequence?

Re: Mendelian principles account for all the diversity we see
I did read the papers, sorry that wasn't clear, I simply find them incomprehensible, and at this point no light has arrived to make them any easier to follow, but I haven't yet got back to them anyway.
I suppose their mystifying effect on me has something to do at least with their assumption of "mutations" as a source of normal variation while of course most creationists regard them as only deleterious accidents. It might help if such interpretive terminology could be translated into simple phenomenological descriptive terms, such as "changes in the sequence of the DNA" instead of "mutations" and if clear reminders were given of where such changes have been actually observed as opposed to where they are extrapolated mathematically etc. Something like that anyway.
Faith I feel that the link in the opening post does have legitimate claims to mutations, and therefore the mutation rate can have some significance. Each human on earth has DNA that is divided into 23 chromosomes. 22 chromosomes are in males and females, only males have the Y-chromosome.
The reason we can be sure of mutations even under flood assumptions, is because there was only one Y-chromosome on the ark, Noah's. All his son's would have inherited the same Y-chromosome, as does science confirm that all men today derive from one single male ancestor. And so any variation now found in genes in the Y-chromosome are caused by subsequent changes to genes since Noah.(mutations in genes)
My problems with Bluegenes assertions are numerous, because its now obvious even to you that if they find 6271 variations when comparing the DNA of 36 people with someone else, not all the variants will be mutations in the 36 individuals, some differences will be mutations in the reference DNA.
This basic and obvious point has not yet been acknowledged by Bluegenes.
Another problem with his analysis is that mutation rates are not yet fully established.
Another problem is that lifestyle factors affect mutations, and it is common knowledge that large portions of early society were hunter-gatherers. ie a more difficult lifestyle.
Another problem, that I am still investigating, is that mutations are caused by radiation, during periods of high radiation mutation rates will be higher.
And so I feel there are far too many uncertainties for definite conclusions at this point in time about the number of generations since the already acknowledged common male ancestor of all humans.

You replied:
Your point isn't accurate. As I've said before, the only mutations that can't be identified within humans and placed are the 470 on the root and "A"'s line. As I keep pointing out, you can distribute those anyway you want, and we've still got our falsification.
You are specifically referring to the distribution between "A" and the 35, which is your fixation.
How do you distribute the 6271 mutations between the 36 and the reference individual? You keep ducking this question.
What I mean by the 600 is that when "A" is matched against any single one of the others, there are always at least 600 loci that differ by a point mutation between the two. That means an average of 300 each. However you distribute it, that fact alone falsifies the standard YEC model with high confidence.
Aah you are reverting back to the 615 again because you cannot explain how to distribute the mutations in the 6271 variant loci between the reference individual and the 36.
All of the variants mean that a mutation has taken place since the common Y ancestor of the two individuals on one lineage or the other. So, it doesn't matter how you distribute them (250 and 350, for example), it's far too many for the common ancestor to be 4,500 years ago.
This point would only stand if they really did compare two individuals. Unfortunately your reference sequence contains bits and pieces of DNA from more than one individual which throws out your logic. It could be 150 and 450, we just don't know.
They don't "drop them" as variants. They use them all in their first tree, all the SNPs in the second, then they leave the SNPs for which they don't have an ancestral allele (~5%) out of the third tree (the 3.2Mb one) presumably because they want the root to be more accurate. In their SNP time estimates for the common ancestor, they include all SNPs once again.

You replied: No. In the chimp.
Haha, you are missing the point. Do you even understand the study?
quote:
Ancestral states
We extracted the ancestral allele for each position that was variable in humans (assumed to be the allele present in chimpanzee) using the Ensembl-Compara pipeline (Vilella et al. 2009), release 66, and obtained calls for 6271 of the total number of 6662 variable sites (Fig. 1; Supplemental Table S2).
On the 3.2Mb tree, that's how they assign the 470 as 285 on "A"'s line and 185 on the other. As the chimp is known to have ~98.3% identical alleles as us on the sections that it shares, it should be pretty accurate. For the rest of the variables that differ within the other 35 individuals, "A" acts as an outgroup as well as the chimp.
To give you an idea of how easily YEC is falsified, look at the common ancestor of the 35 non-A individuals on the 3.2Mb tree. They average over 150 mutations from this ancestor. If we take my suggested very highest plausible mutation rate of 10 10−8, that gives us 0.32 mutations per. generation on that area. Divide 150 by 0.32 and we get 468.75, which is the number of generations back to that ancestor which, multiplied by 25 gives us 11,719 years as the date of that individual. If we do the same thing on the more normal mutation rate found in the Chinese pedigree study (3 10−8), we get 39,062 years.
That ancestor is not the ancestor of the "A" groups, and neither is the ancestor of all 36 the common ancestor with the rare group that was discovered this year, and which seems to be at least twice as far back again.
Haha all your calculations are irrelevant because they were left with 6271 variable loci when comparing with the reference sequence. Just because the loci VARY WITH THE REFERENCE SEQUENCE does not mean the variants are mutations.
In addition if there was exposure to radiation, or lifestyle factors , this could greatly affect mutation rates, and my compressed timeframes view REQUIRES exposure to radiation due to my claim that radioactive isotopes actually decayed far faster than is currently measured.
In addition the Y chromosome mutation rate is approximately 4.8 times higher than elsewhere, however this figure "4.8" I found in Wikipedia, and cannot verify it elsewhere. The mutation rate in the Y-chromosome is an unknown, and until you give more precise figures on specifically the Y-chromosome mutation rate this whole thread is irrelevant to actual reality.

Re: Database alignment and searching.
Have you considered just how much extra radiation would have been produced under your ridiculous scheme? Well guess what? You don't have to rely on Bible hating scientists for your answer.
Interestingly enough, there is a study examining exactly how much additional radiation and radiation energy would be produced by such accelerated decay rates. The eight year study called RATE was produced by the Institute for Creation Research. The RATE concluded that there was indeed evidence of billions of years worth of radioactive decay (assuming conventional decay rates). They also found that the amount of heat produced would have melted the earth if produced over the short time Genesis claims that the earth existed.
Now being good Christians, they concluded that the accelerated decay happened anyway. But they could not make things work without some unknown intervention at work. Is this your argument too
I need links, I need calculations. I don't care about the source of information, if the information makes sense then I respect it.
Could you kindly give me your sources.

Re: Database alignment and searching.
No. I keep explaining to you that if you want to find the variations between 36 individuals, you compare them to each other. You wouldn't include the reference individual in your search for the variants, because there's no point. You would then have to take it back out again, which is easy enough, but why put it in in the first place?
You are in fact incorrect.
Not only are you incorrect, I already pointed this out in my post 76:
"Thus, despite the small number of individuals, there was good geographical representation of global populations and of the haplogroup tree. After QC and validation, we extracted 6662 high-confidence variants (i.e., sites that differ from the Y chromosome reference sequence)"
SITES THAT DIFFER FROM THE Y-CHROMOSOME REFERENCE SEQUENCE. Not differences from each other, but differences from the reference sequence.
It's easy to for them to compare any 2 individuals, and they have to compare them all to get the variants and make their trees. The Y reference is not included in the search for variants. It would be stupid to include it. It's the same as the idea that you were pushing post after post that they had identified the variants by comparing the 36 to the chimp.
The variants in 36 individuals are easily established once they're aligned to each other on a database. They are the loci (rows in my description), on which they are not all identical. In other words, you remove all the rows on which all 36 match (over 99.9% of the 8.97 Mbs).
These comments are based on your misunderstanding of the study. As pointed out above, they did not compare with eachother , they compared the 36 with the reference sequence. Now its up to you to explain where the mutations are in 6662 variant loci. The reference sequence , or the 36 individuals? How do we divide the mutations between them?
I explained that to you. That 4.8:1 is not the ratio of the Y SNP mutation rate to that of the rest of the genome, but the estimated male to female mutational difference. As the rest of the material passes through the male half of the time, the mutation rate ratio should be 5:3. For example, if the general mutation rate is about 1.8 * 10-8, the Y would be about 3.0 * 10-8, which is exactly what we find on the Chinese 13 generation pedigree study.
Your conclusion of 5:3 is way too simplistic and does not acknowledge the full range of factors that increase mutations in the y-chromosome:
"The Y chromosome is passed exclusively through sperm, which undergo multiple cell divisions during gametogenesis. Each cellular division provides further opportunity to accumulate base pair mutations. Additionally, sperm are stored in the highly oxidative environment of the testis, which encourages further mutation. These two conditions combined put the Y chromosome at a greater risk of mutation than the rest of the genome"
Also a lack of recombination in the Y-chromosome.
The following study seems to indicate a much higher Y-chromosome mutation rate than either of us has quoted so far, but does not focus on SNP's. This study claims the field needs further study to establish y-chromosome mutation rates:
http://www.ncbi.nlm.nih.gov/...s/PMC1378017/pdf/10762544.pdf
I don't find your simplistic ratio of 5:3 very convincing, seems like a thumbsuck to me.
That's just wishful thinking on your part. We can be 99% confident on the data available that it is not over 10.0 * 10-8. That's more than 3 times what's found in the Chinese study.
I pointed out in the last post that the common ancestor of the 35 non-A individuals falsifies Noah at 4,500 years. In order to squeeze him down to that time, you would have to cut the generation gap to 20, and have a mutation rate of ~20*10-8, and allocate all the 470 mutations to the "A" individual.
Wishful thinking on your part
1) Scientists themselves still claim Y-chromosome mutation rates are uncertain
2) You are still showing a misunderstanding of where those 6662 variants come from, this along with other factors directly affects your mutation count on which your argument is based.
3) You are ignoring the possibility of lifestyle factors , which have been proven to affect rates
4) My compressed timeframes view requires more radiation, which has a direct effect on mutations.
He's certainly not the common Y ancestor of all humans, and neither is the common ancestor of all 36, because of the recent discovery of a new and ancient haplogroup that differs as much or more from "A" as "A" does to the others
Could you post a link. This is very interesting for me.

Re: Database alignment and searching.
Yes, they align them with the Y reference, but the reference is not included in the 6662 variants, because they only want the variants between the others. The loci on which the reference differs from all 36 of the real people are its own mutations, and these are automatically excluded. It's the same if they wanted to exclude any one of the 36 from he tree. It's easily done by eliminating the loci on which that individual differs from all others.
Let me repeat my quote from the actual study:
"Thus, despite the small number of individuals, there was good geographical representation of global populations and of the haplogroup tree. After QC and validation, we extracted 6662 high-confidence variants (i.e., sites that differ from the Y chromosome reference sequence)"
Your response:
"the loci on which the reference differs from all 36 of the real people are its own mutations"
You say that they "automatically exclude" the mutations in the reference sequence. Please quote from the study to prove your point, I have had the courtesy to back up my statements with actual quotes.
Do you understand that it's easy to know what variants are unique to the reference sequence, because it will differ from all 36 on those loci. Are you suggesting that they, like you, can't figure that out? They don't put it step by step in the paper, because it's obvious, and their normal readership will understand that, and therefore would not raise the objections you're raising. Then you ask:
mindspawn writes:
How do we divide the mutations between them?
Which I've already gone to great lengths to explain. Are you seriously suggesting that the mutations cannot be assigned? Surely you can work out that in order to draw trees, they have to compare them to each other, and that they have all the information necessary in their database for allocation, except for the root of the tree, for which an outgroup is necessary.
You would be surprised how many time scientists miss some logic in making their conclusions and devising their studies. Applying what you think is logical to a document that explains things differently is just not good enough to make your point.
And even if you were correct, your reference to another common ancestor further back in time ruins your mutation count, because its possible that all 36 individuals had the mutation, and the reference sequence has the original allele. The only method in which to tell the difference is to actually have the ancestral sequence, which they do not have, and they had to use the chimp to estimate the ancestral alleles.
I believe the more unique variants found in small proportions of the population are more likely to be true mutations, and so referring to your graph, we can be pretty confident after the 52/41 , that these are all true mutations. But the 54, the 13 , the 41, the 185 and the 285 have a high chance of being ancestral alleles and not mutations which ruins your count.
Exactly. And the other material passes through the sperm 50% of the time, giving it the same risk on half the transfers, but about 1/5 on the other half. That gives you a 5:3 overall ratio.
You are looking at one generation, however you need to factor in long term selection through variation via recombination. De-selection is limited regarding the Y-chromosome because it does not recombine.
regarding my 4 points,
1) Ok the point is partially accepted, they are beginning to define an acceptable range that is currently applicable. This however does not reflect on past rates.
2) We are still in total disagreement.
3) You write: Not at all. I've pointed out the reality of variant rates along lineages, and that you can see by how much lineages can vary for a prolonged period of time on the charts
You seem to miss my point here, its possible that ALL humans had a worse lifestyle during the first generations after the flood. They were also having children at older ages. The accumulation of mutations in the first few generations could have been dramatic compared to today, based on age and lifestyle factors.
4) You say: And a direct effect on disease. Your model requires a very healthy population in order to spread rapidly around the world before the end of the stone age, whenever you think that was.
This was a weak reply, we are looking at the number of germline mutations already existing in populations and how rapidly they were formed. Even now with these mutations, populations can grow rapidly, so your point that populations would not have been healthy with many germline mutations does not apply, because we are healthy enough to expand rapidly. Did mankind rapidly gain its germline mutations during a period of high radioactivity? I believe its possible.

Re: Database alignment and searching.
Again, you're not making sense. All those figures you mention are variant loci. That means for each one, there has been a mutation since the common ancestor. All the numbers you mentioned can be established using both "A" and the chimp as an outgroup, excepting the 185 and 285. For those, the chimp is the only outgroup, but as it's established that the chimp is ~98.3% identical to us on SNPs over the whole Y, the allocation of those 470 variants will be approximately correct (regardless of common descent or "common design").
Bluegenes, thanks for the civil discussion. I am not sure why it took you so long to point out the reference sequence, but other than that particular delay you have communicated well which is more than I can say for nearly everyone else in this forum.
There are so many variables that do affect your stance, but I have probed and probed for weaknesses in your argument that would have a major effect and generally feel that you have answered well.
The chimp does play a significant role in the study, but even so it has the role of reducing the mutations to a more reliable core and so even though there are some flaws in using the chimp I do see your 98.3 % point and your earlier point about the same logic being applicable under common design or common ancestry.
So to conclude I generally agree with you on your points regarding my questions 1 and 2, despite the uncertainty regarding some variables. So your opening post makes sense regarding current rates, so we are now disputing the application of those rates to times past.
Apart from that being an unsupported claim, you seem to miss my point. Look at the slowest mutating lineage of the 35 DR individuals (it's "D"). There are 140 mutations back to the common ancestor of the 35, and we can find some of the fastest mutators with slightly over 200, which is ~50% more. If we then assume that the 13 generations of Chinese to be mutating at that slowest rate (although all the Asians on the chart aren't particularly slow), and consider the fact that their rate is 3.0*10-8, then we can see that the highest likely mutation rate over a prolonged period would be 4.5*10-8.
I'm not getting you here, could you explain this again please. I don't see how we can work out mutation rates from that study itself, we need outside mutation rates to determine the timespans involved.
As for your dramatic accumulation of mutations in the first few generations, what mutation rate are you suggesting? If you put it at 10 times the Chinese rate for ten generations, you've got about 10 mutations on that 3.2Mb section, which is no help to you at all. It puts "A" at 275, and the DR line at 175. And you're going to have problems with detrimentals right across the genome at that very high rate. There's absolute zero evidence that the rate can be that high, and unsupported speculation doesn't weaken an evidence based falsification.
I did post a link that showed that lifestyle effects mutation, and so my claim is not unsupported. I added an additional claim that age of parenthood affects mutations, which is widely known, here is a link to support that claim:
Just a moment...
Abstract
"The number of de novo mutations in the germline can be expected to increase with age in males, therefore females might decrease mutation load in their progeny by avoiding mating with older males. Here, I propose that female polyandry can be more effective in decreasing the risk of genetic disorders in progeny than pre-copulatory mate choice, particularly if sperm competitiveness declines more steeply with age than other traits affecting chances of males to mate. If faster ageing of spermatogenic tissue causes older males to transfer inadequate numbers of functional sperm, polyandry would also benefit females directly."
Now the bible claims that the males were vastly older than today when having their first offspring during the early post-flood years, so the accumulation of germline mutations during a difficult lifestyle and also from older males per generation would have been much higher during the first few generations. Shem was 100 years old, most others had their FIRST child in their thirties, later Terah had his children in his seventies, Abraham at a late age as well.
Paternal age effect - Wikipedia
The population geneticist James F. Crow said that the fact that DNA in sperm degrades as men age and can then be passed along to children in permanently degraded and irreparable form, which they likely pass on as well, means that the "greatest mutational health hazard to the human genome is fertile older males"
Eight times as many mutations in a 70 year old compared to a 20 year old, so there is some exponential effect occurring:
Fathers bequeath more mutations as they age | Nature
"A 36-year-old will pass on twice as many mutations to his child as a man of 20, and a 70-year-old eight times as many, Stefnsson’s team estimates."
Surely you see what's wrong with that? The lineages that get severe detrimentals or accumulations of mild detrimentals get selected out. If you increase the mutation rate across the genome, you increase the detrimentals. So, if you want the early population to have a mutation rate of about 10 times the present, for example, you've got a very unhealthy population. The higher the rate of negative mutations, the greater the death rate before adulthood, and the harder it is for the population to expand.
Bluegenes, we are looking at the existing germline mutations that exist in all of us. We still survive and breed even with these mutations, whether they came at the human population rapidly or slowly. The early population would have had less mutations than us, whether gained rapidly or slowly. We survive, of course they would have survived having even less than us.
Why?
High radioactivity causes mutations. If rocks decayed faster in the past, the resulting radiation would have caused more mutations.
I believe current rates of radioactivity are slowed down by the muon effect. Muons when colliding with earth generate many neutrons, which in turn prevent the decay of heavy elements. Under past conditions the magnetic field was stronger, preventing many muons from striking earth, the background neutrons were less and hence parent isotopes decayed at a faster rate, producing radiation that would have affected the mutation rate.

Re: The RATE Group Fiasco
How can you ask for a link to the RATE Study? This was a study done by the YEC/ID flagship organization, The Discovery Institute, and is widely known and available in just a simple search without even trying hard. Are you really that incapable?
From now on I will restrict my replies to posts that contain no personal attacks, even if somewhere in the post there are some facts or good questions.

Re: Database alignment and searching.
The link previously provided was to previous discussion of the RATE study. I repeat that link Heat and radiation destroy claims of accelerated nuclear decay .
Here is a link to the actual study:
http://www.icr.org/i/pdf/research/rate-all.pdf
Nonukes, that's a 444 page document. Could you kindly quote the portion that you feel is relevant.
http://www.icr.org/i/pdf/research/rate-all.pdf
For completeness here are some rebuttals from "Old Earth Ministries" and other places. I understand that this information may not be helpful in preparing your defense of rapid decay, but please vet your ideas before making us do that for you. [1]
RATE Project Index
RATE and Age of the Earth - Radiometric Dating
[1] Hopeless plea. Creation scientists never do vet their own stuff as doing so interferes with a preferred "see what sticks" posting methodology.
None on those rebuttals deal with my muon hypothesis. Muons are currently slowing down decay by producing many neutrons on impact with the earth. (neutrons are known to slow down the decay of heavy isotopes). During past periods of strong magnetic fields, the muon effect would have been less, the decay more rapid.

Re: Database alignment and searching.
Quotes and references and discussion are in Heat and radiation destroy claims of accelerated nuclear decay. Of course you've ignored that twice already.
That's a whole thread. Could you kindly summarise your point and refer me to a specific link. I haven't got the time to look through all those posts, and at this stage I'm not even sure what I would be looking for.

Re: Database alignment and searching.
No, they are not, at least not in any physically relevant situation.
And of course you haven't thought things through, you're just spewing any nonsense that comes into you head. If the decay of heavy isotopes has been slowed then the dates we are measuring are too young. That is, the samples would be significantly older that our measurements say they are.
I suggest you think that through. Rates are slow now. This means that they overestimate time periods when comparing ratios of parent to daughter isotopes. Without the slowdown, rocks would rapidly decay into daughter isotopes which I believe is what happened from about 4400 years ago until about 1700 years ago. (approximately).

Re: When natural selection can't keep up with mutation.....
Yes. That's the inevitable course of the thread.
Please note there are so many variables, that I am agreeing only that current rates in that 3.2 mb section do not conform with a 4500 year time period. The extent is largely unknown.
The use of the genome of only one individual "A" to establish most of those variants has insufficient scope to be truly confident in the conclusions. If they had used 35 "A" individuals and 35 of the rest, we could be more confident that they matched the sections/sequences before comparing them. Remember 600 of the ~2000 variants were found in the "A" individual. Any error in matching sequences would have been exacerbated through the low numbers in the sample (one rare individual, 35 common ones). I know they are confident of their results, nevertheless there is a principle that the smaller the sample the less confidence we have in the results.
In addition the exact rate of accumulation of germline mutations in the y-chromosome compared to the elimination through recombination in other areas of the genome is unknown, unless you can find a study to show the differences in germline accumulation over time. I cannot find clear figures anywhere on this effect of the lack of recombination over time.
What I was talking about is the relative differences on different lineages back to the point of a common Y ancestor. The fastest can have about 50% more mutations than the slowest, meaning that the variance (which relates to all the variant factors we've been discussing) is about 25% either side of the average. I then pointed out that if we generously assume the Chinese 13 generations to be as slow as the slowest lineage, the highest mutating lineages are going at about 4.5*10-8, to which I could add that the average rate would be ~3.75*10-8. Bear in mind that, assuming 180 generations back to a 4,500 year old common Y ancestor, you need the average mutation rate over time to be ~52*10-8 to account for 300 mutations from the ancestor on any lineage on that 3.2Mb section.
Ok but of course I'm disputing your 50% variance through 3 additional factors in the past:
A) Lifestyle
B) Paternal age
C) Radiation
So I feel your point above is irrelevant due to our ongoing discussions about factors that would increase the mutations rates above the modern observed range of mutation rates.
Nice to see a Christian posting research that points out the possible benefits of female promiscuity. Yes, I know all this, and agree, but it doesn't support your claim. See below
You started off arguing for an average generation gap of 18!
He means that people like Shem, Terah and Abraham are health hazards. I agree
Yes, that's all fine. Now, work it out with this model. Lineage "X" goes back to the common ancestor with an average generation gap of 36 years, and therefore twice the mutations per generation than lineage "Z", which has a generation gap of 20 years, and therefore 1.8 times as many generations back to the ancestor. Take both back to the time of their common ancestor, and the result is a ratio of 10 mutations (for X) to each 9 (for Z). You see greater differences than that on the phylogenetic tree chart!
.
Lol! I assume you promote promiscuity if its "nice to see".
I understand your maths, however its not that simple if you take into account the exponential effect with age, ie the number of mutations approximately double up every 16 years:
3 mutations at 20
6 mutations at 36
12 mutations at 52
24 mutations at 68 (8 times the mutations at age 70 )
48 mutations at 82
96 mutations at 98
A couple of ancient fathers in each lineage would have a dramatic effect on the gaining of germline mutations, especially if there were exacerbating factors like excess radiation during their lifetimes. But I do admit that on its own, paternal age is not enough to explain the observed germline mutations.
.
Would you like to increase the early mutation level to the extent that every single individual conceived has a lethal mutation?
What happens is that population groups get rid of detrimental mutations by producing an average of more than 1 offspring per. adult. A population can then maintain stability, or increase in size, because the extras cover for chance accidental deaths and deaths due to detrimental mutations. But if the mutation rate increases, the percentage of conceptions with detrimental mutations increases, which means the number of births/conceptions per. adult needs to increase as well in order to maintain/increase the population size. There's a limit to how high mutation rates can go.
I understand this, but looking at my radiation argument, this relates specifically to the strength of the magnetic field which was stronger for quite a long period of time. (~2000 years). Its possible that higher birth rates and the length of time would have minimized the effect you are referring to, unless you have more exact figures that can strengthen your case.
For the moment, I'll leave your geophysics alone, apart from agreeing that higher radioactivity can increase mutation rates, and I'll discuss the genetic angle. What I think we should look into is estimates on the current (low radiation) detrimental mutation rate. By this I mean the rate per. individual born. I've seen this estimated as high as 1.3 per individual, with most of these causing only very mild decreases in fitness, but a minority, perhaps 10%, causing significant decreases. If that's about right, imagine increasing the whole genome mutation rate by 10 times. That would mean 13 new detrimentals per. head, at least one causing a significant decrease in fitness on its own. I think that would mean extinction.
What I'm wondering is whether humans could have a rate even double what it is now, and still have a growing population (without the help of modern medicine). I think we should look into it, so I'll check out the recent research.
What you're doing now is correct from a YEC point of view. You won't find significant inaccuracies in the research papers I've been using (remember the two recent similar studies I linked to that reflect the results of the first). So, as I suggested to Faith earlier, the only thing for YECs to do is to argue for a very high mutation rate since Noah, especially early on. I knew we would end up here, in the realm of implausibly high mutation rates, deformity and DEATH.
Cool, looking forward to your figures. I'm not sure of the proportion of the population that does have disabilities or reduced fitness levels, apparently about 2.5% are born with noticeable disabilities, but nearly everyone inherits some weakness that could result in slightly higher chances of death from a certain affliction. Even if early populations had a far higher proportion of disabilities, about 10%, I believe they would have coped. We can picture a scenario in which a farming family has about 10 offspring with 1 of those with a disability, there is no reason why that family would not survive, and the other 9 have offspring. And so 10% compared to 2.5 % would not wipe out the population.

Re: Rapid evolution after Noah
John Woodmorappe (a pseudonym for a high school teacher named Jan Peczkis), in his article titled The non-transitions in ‘human evolution’—on evolutionists’ terms, posted on the answersingenesis.org website, has argued this very thing. He writes:
The relevant evidence clearly shows that Homo sapiens sensu lato is a separate and distinct entity from the other hominids. No overall evolutionary progression is to be found. Adam and Eve, and not the australopiths/habilines, are our actual ancestors. As pointed out by other creationists [e.g., Lubenow9], Homo ergaster, Homo erectus, Homo heidelbergensis, and Homo neanderthalensis can best be understood as racial variants of modern man—all descended from Adam and Eve, and most likely arising after the separation of people groups after Babel.
So Woodmorappe sees the change from modern man, i.e., Adam and Eve, to these four species of fossil man taking place since the Babel incident, which occurred after the global flood and in the range of 4,000 to 5,300 years ago.
Homo ergaster is dated to between about 1.8 million and 1.3 million years ago, so the change from that critter to modern man took at least 1.1 million years. Now creationists propose a change from modern man to Homo ergaster in about 4,500 years (with instant fossilization and burial, along with a return to normal evolutionary rates). This post-Babel change from modern man to Homo ergaster would require a rate of evolution on the order of 250 times as rapid as scientists see for the change from Homo ergaster to modern man!
Most creationists deny evolution occurs on this scale at all. Now creationists have not only proposed such a change themselves, but they see it operating 250 times faster and in reverse!
No wonder creation "science" is considered to be such a joke.
Outward changes and the establishment of new race groups can occur without any significant genetic change whatsoever. Allele frequencies can determine many changes, and allele frequencies can occur over a few generations.
Homo erectus, homo ergaster, and Neanderthals are merely extinct human race groups, nothing more. Its a big assumption to see an extinct race group and assume their bones are earlier then the early Sumerian civilization. We need very careful dating methodology to establish earlier dates, if you present your findings on the dating methods used for homo ergaster we can discuss this further but its probably more relevant to another thread.
Homo australopithus is quite simply an extinct ape.

Bluegenes, due to admin's attitude to moderation I will no longer be participating in these forums. You are welcome to message me privately and we can continue this discussion, thank you for your civility during our discussion.
This is a quote from admin, he is allowing both sides a "free for all" which obviously is to my disadvantage:
If you're not listening to my moderation and I'm not suspending you, then when others don't listen to my moderation how can I suspend them? Since so many are not listening to moderation my options are either to close the thread or just let things continue. I'm opting to keep the thread open.
