  1. 1) That's just an outright lie ya fucking putz.
    2) Right strawman fabricatons are ALL you have.
    3) Might as well be, the truth doesn't seem to matter to you one whit.

    4a) What definition of evolution did he back?
    4b) What makes you think I take it personally?

    "In 1978, a detailed examination was carried out by a team of American scientists called STURP. STURP found no reliable evidence of forgery, and called the question of how the image was formed "a mystery""

    'According to former Nature editor Philip Ball, "it's fair to say that, despite the seemingly definitive tests in 1988, the status of the Shroud of Turin is murkier than ever. Not least, the nature of the image and how it was fixed on the cloth remain deeply puzzling"'

    This was funny....
    https://zwingliusredivivus.wordpres...d-of-turin-is-not-the-burial-shroud-of-jesus/

    "The results date the cloth to between 300 B.C. and 400 A.D., per The Telegraph."

    So..... 300BC.----> 0 <-------400A.D. :D

    Also - no one mentions the history of art regarding the image....

    Early artistic depictions of Jesus look like this:
    http://en.wikipedia.org/wiki/File:Christ_Pantocrator_Deesis_mosaic_Hagia_Sophia.jpg

    Flat and 2 dimensional...

    Giotto and perspective don't come until later, so the 3D aspect of the image on the shroud wouldn't have even been considered by an artist.

    And why create it as a photographic negative when photography won't be invented for hundreds of years? :D

    No other burial linens have been brought forth with an image. If it were the by-product of a biological reaction, there should be lots of these around....

    Again - for some, it doesn't even matter....

    But for others, not only can it not be - it MUST not be....

    :D

    Marketmasher, I know I should not bother to respond, but you do seem to be one of the more reasonable contributors here. It seems to be a fact that at this point there is uncertainty regarding how the image was formed. I don't think there is much credible disputing of that. And the DNA and other evidence apparently is conclusive that there is human DNA present and blood, and It seems to have been established that it is human blood, as opposed to a goat or other animal. It seems not out of the question that the Shroud might actually be someone's burial shroud. A problem that crops up however is that at least one expert has stated that the body proportions are out of line with what they should be. But let's not let that deter those who want to believe it is an actual burial shroud, or perhaps a dead body, even a crucified body, was at some point wrapped in it.

    However the carefully done C-14 dating by three of the most competent C-14 dating labs in the world all date it to the medieval period. And there is no credible evidence, other then unfounded supposition, that the sample for that dating came from a later repair. In fact it did not, and the representatives of the testing labs present to advise on valid sampling procedure would certainly have objected if the sample had not come from non-repaired linen continuous with that imprinted with the image. That question has been thoroughly addressed by the scientists working on the dating project. Repairs, and apparently there are some, are easily seen. Furthermore the question of contamination has been thoroughly addressed and there was none that could have significantly affected the result enough to move the dating back to the time of Christ. Recall that the samples were very thoroughly cleaned, and the amounts of contamination that would have had to have been present to significantly alter the results was well beyond any amount that could have been present after cleaning.

    I'm afraid for the believers sake that the C-14 results are too definitive for the Shroud to have been the burial shroud of the biblical Christ. It is nevertheless an interesting relic about which obviously many questions remain. So I have to agree with mr. Ball when he says: "it's fair to say that, despite the seemingly definitive tests in 1988, the status of the Shroud of Turin is murkier than ever. Not least, the nature of the image and how it was fixed on the cloth remain deeply puzzling"'

    But of course there is nothing murky about the Shroud not being the burial Shroud of the biblical Jesus. It isn't. The C-14 tests are just too definitive, to use Mr. Ball's word, to allow for that.

    I don't suppose that no matter how many more samples are taken and C-14 dated. It will make any difference. Every Easter there is going to be a new revelation, new data, ad infinitum. And we can confidently predict that these new revelations will appear in the press, once again, in the days leading up to the Easter display of the Shroud.

    Everyone seems to want to get to the UNBIASED facts. But you, like one of those mentioned by MarketMasher, are one for whom the shroud of turin MUST NOT turn out to be the actual burial cloth of Jesus.

    You're stuck on a failed study and refuse to consider other evidence. All of your doubletalk and run on sentences won't change that.

    Criticisms of the Carbon Dating results...

    https://en.wikipedia.org/wiki/Radiocarbon_14_dating_of_the_Shroud_of_Turin

    The sample was part of a later repair[edit]

    Although the quality of the radiocarbon testing itself is unquestioned, criticisms have been raised regarding the choice of the sample taken for testing, with suggestions that the sample may represent a medieval repair fragment rather than the image-bearing cloth.[40][41][42][43] It is hypothesised that the sampled area was a medieval repair which was conducted by "invisible reweaving". Since the C14 dating at least four articles have been published in scholarly sources contending that the samples used for the dating test may not have been representative of the whole shroud.[44][45]

    These included an article by American chemist Raymond Rogers, who conducted chemical analysis for the Shroud of Turin Research Project and who was involved in work with the Shroud since the STURP project began in 1978. Rogers took 32 documented adhesive-tape samples from all areas of the shroud and associated textiles during the STURP process in 1978.[46] He received 14 yarn segments from Prof. Luigi Gonella (Department of Physics, TurinPolytechnic University) on 14 October 1979, which Gonellla told him were from the Raes sample. On 12 December 2003, Rogers received samples of both warp and weft threads that Prof. Luigi Gonella claimed to have taken from the radiocarbon sample before it was distributed for dating. The actual provenance of these threads is uncertain, as Gonella was not authorized to take or retain genuine shroud material,[47] but Gonella told Rogers that he excised the threads from the center of the radiocarbon sample.[46]

    Raymond Rogers stated in a 2005 article that he performed chemical analyses on these undocumented threads, and compared them to the undocumented Raes threads as well as the samples he had kept from his STURP work. He stated that his analysis showed: "The radiocarbon sample contains both a gum/dye/mordant coating and cotton fibers. The main part of the shroud does not contain these materials".[48] He speculated that these products may have been used by medieval weavers to match the colour of the original weave when performing repairs and backing the shroud for additional protection. Based on this comparison Rogers concluded that the undocumented threads received from Gonella did not match the main body of the shroud, and that in his opinion: "The worst possible sample for carbon dating was taken."[49]

    As part of the testing process in 1988, Derbyshire laboratory in the UK assisted the Oxford University radiocarbon acceleration unit by identifying foreign material removed from the samples before they were processed.[50] Professor Edward Hall of the Oxford team noticed two or three "minute" fibers which looked "out of place",[50] and those "minute" fibers were identified as cotton by Peter South (textile expert of the Derbyshire laboratory) who said: "It may have been used for repairs at some time in the past, or simply became bound in when the linen fabric was woven. It may not have taken us long to identify the strange material, but it was unique amongst the many and varied jobs we undertake.” [50]

    The official report of the dating process, written by the people who performed the sampling, states that the sample "came from a single site on the main body of the shroud away from any patches or charred areas."[51]

    Mechthild Flury-Lemberg is an expert in the restoration of textiles, who headed the restoration and conservation of the Turin Shroud in 2002. She has rejected the theory of the "invisible reweaving", pointing out that it would be technically impossible to perform such a repair without leaving traces, and that she found no such traces in her study of the shroud.

    Prof H E Gove, former professor emeritus of physics at the University of Rochester and former director of the Nuclear Structure Research Laboratory at the University of Rochester, helped to invent radiocarbon dating and was closely involved in setting up the shroud dating project. He also attended the actual dating process at the University of Arizona. Gove has written (in the respected scientific journal Radiocarbon) that: "Another argument has been made that the part of the shroud from which the sample was cut had possibly become worn and threadbare from countless handlings and had been subjected to medieval textile restoration. If so, the restoration would have had to be done with such incredible virtuosity as to render it microscopically indistinguishable from the real thing. Even modern so-called invisible weaving can readily be detected under a microscope, so this possibility seems unlikely. It seems very convincing that what was measured in the laboratories was genuine cloth from the shroud after it had been subjected to rigorous cleaning procedures. Probably no sample for carbon dating has ever been subjected to such scrupulously careful examination and treatment, nor perhaps ever will again."[52]

    In 2010, professors of statistics Marco Riani and Anthony C. Atkinson wrote in a scientific paper that the statistical analysis of the raw dates obtained from the three laboratories for the radiocarbon test suggests the presence of contamination in some of the samples. They conclude that: "The effect is not large over the sampled region … our estimate of the change is about two centuries."[53]

    In December 2010 Professor Timothy Jull, a member of the original 1988 radiocarbon-dating team and editor of the peer-reviewed journal Radiocarbon, coauthored an article in that journal with Rachel A Freer-Waters. They examined a portion of the radiocarbon sample that was left over from the section used by the University of Arizona in 1988 for the carbon dating exercise, and were assisted by the director of the Gloria F Ross Center for Tapestry Studies. They viewed the fragment using a low magnification (~30×) stereomicroscope, as well as under high magnification (320×) viewed through both transmitted light and polarized light, and then with epifluorescence microscopy. They found "only low levels of contamination by a few cotton fibers" and no evidence that the samples actually used for measurements in the C14 dating processes were dyed, treated, or otherwise manipulated. They concluded that the radiocarbon dating had been performed on a sample of the original shroud material.[54]

    According to professor Christopher Ramsey of the Oxford Radiocarbon Accelerator Unit in 2011, "There are various hypotheses as to why the dates might not be correct, but none of them stack up."[55]

    In March 2013 Giulio Fanti, professor of mechanical and thermal measurement at the University of Padua conducted a battery of experiments on various threads that he believes were cut from the shroud during the 1988 Carbon-14 dating, and concluded that they dated from 300 B.C. to 400 A.D., potentially placing the Shroud within the lifetime of Jesus of Nazareth.[56][57][58][59][60][61][62] Because of the manner in which Fanti obtained the shroud fibers, many are dubious about his findings. The shroud’s official custodian, Archbishop Cesare Nosiglia of Turin, told Vatican Insider: "As there is no degree of safety on the authenticity of the materials on which these experiments were carried out [on] the shroud cloth, the shroud's custodians cannot recognize any serious value to the results of these alleged experiments."[63][64] Barrie Schwortz, a member of the original STURP investigation team, commented on Fanti’s theory: "But it would be more convincing if the basic research had first been presented in a professional, peer-reviewed journal. If you’re using old techniques in new ways, then you need to submit your approach to other scientists."[63]

    The dating contradicts other evidence[edit]
    Raymond Rogers [65] argued in the scientific journal Thermochimica Acta that the presence of vanillin differed markedly between the unprovenanced threads he was looking at, which contained 37% of the original vanillin, while the body of the shroud contained 0% of the original vanillin. He stated that: "The fact that vanillin cannot be detected in the lignin on shroud fibers, Dead Sea scrolls linen, and other very old linens indicate that the shroud is quite old. A determination of the kinetics of vanillin loss suggest the shroud is between 1300 and 3000 years old. Even allowing for errors in the measurements and assumptions about storage conditions, the cloth is unlikely to be as young as 840 years".[48]

    It has been stated that Roger’s vanillin-dating process is untested, and the validity thereof is suspect, as the deterioration of vanillin is heavily influenced by the temperature of its environment - heat strips away vanillin rapidly, and the shroud has been subjected to temperatures high enough to melt silver and scorch the cloth.[47] Rogers' analysis is also questioned by skeptics such as Joe Nickell, who reasons that the conclusions of the author, Raymond Rogers, result from "starting with the desired conclusion and working backward to the evidence".[66]

    The sample was contaminated by bacteria[edit]
    Pictorial evidence dating from c. 1690 and 1842 indicates that the corner used for the dating and several similar evenly spaced areas along one edge of the cloth were handled each time the cloth was displayed, the traditional method being for it to be held suspended by a row of five bishops. Others contend that repeated handling of this kind greatly increased the likelihood of contamination by bacteria and bacterial residue compared to the newly discovered archaeological specimens for which carbon-14 dating was developed. Bacteria and associated residue (bacteria by-products and dead bacteria) carry additional carbon-14 that would skew the radiocarbon date toward the present.

    Rodger Sparks, a radiocarbon expert from New Zealand, had countered that an error of thirteen centuries stemming from bacterial contamination in the Middle Ages would have required a layer approximately doubling the sample weight.[67] Because such material could be easily detected, fibers from the shroud were examined at the National Science Foundation Mass Spectrometry Center of Excellence at the University of Nebraska. Pyrolysis-mass-spectrometry examination failed to detect any form of bioplastic polymer on fibers from either non-image or image areas of the shroud. Additionally, laser-microprobe Raman analysis at Instruments SA, Inc. in Metuchen, New Jersey, also failed to detect any bioplastic polymer on shroud fibers.

    Professor Harry Gove, director of Rochester's laboratory (one of the laboratories not selected to conduct the testing), once hypothesised that a "bioplastic" bacterial contamination, which was unknown during the 1988 testing, could have rendered the tests inaccurate. He has however also acknowledged that the samples had been carefully cleaned with strong chemicals before testing.[68] He noted that different cleaning procedures were employed by and within the three laboratories, and that even if some slight contamination remained, about two thirds of the sample would need to consist of modern material to swing the result away from a 1st Century date to a Medieval date. He inspected the Arizona sample material before it was cleaned, and determined that no such gross amount of contamination was present even before the cleaning commenced.[7]

    The sample was contaminated by smoke or reactive carbon[edit]
    Others have suggested that the silver of the molten reliquiary and the water used to douse the flames may have catalysed the airborne carbon into the cloth.[69] The Russian Dmitri Kouznetsov, an archaeological biologist and chemist, claimed in 1994 to have managed to experimentally reproduce this purported enrichment of the cloth in ancient weaves, and published numerous articles on the subject between 1994 and 1996.[70][71][72][73][74][75][76][77] Kouznetsov's results could not be replicated, and no actual experiments has been able to validate this theory, so far.[78] Professor Gian Marco Rinaldi and others proved that Kouznetsov never performed the experiments described in his papers, citing non-existent fonts and sources, including the museums from which he claimed to have obtained the samples of ancient weaves on which he performed the experiments.[79][80][81][82] The Russian was arrested in 1997 on American soil under allegations of accepting bribes by magazine editors to produce manufactured evidence and false reports.[83]

    Jull, Donahue and Damon of the NSF Arizona Accelerator Mass Spectrometer Facility at the University of Arizona attempted to replicate the Kouznetsov experiment, and could find no evidence for the gross changes in age proposed by Kouznetsov et al. They concluded that the proposed carbon-enriching heat treatments were not capable of producing the claimed changes in the measured radiocarbon age of the linen, that the attacks by Kouznetsov et al. on the 1988 radiocarbon dating of the shroud "in general are unsubstantiated and incorrect", and that the "other aspects of the experiment are unverifiable and irreproducible."[84]

    In 2008 Dr John Jackson of the Turin Shroud Center of Colorado proposed a new hypothesis – namely the possibility of more recent enrichment if carbon monoxide were to slowly interact with a fabric so as to deposit its enriched carbon into the fabric, interpenetrating into the fibrils that make up the cloth. Jackson proposed to test if this were actually possible.[85] Professor Christopher Ramsey, the director of the Oxford University Radiocarbon Accelerator Unit, took the theory seriously and agreed to collaborate with Jackson in testing a series of linen samples that could determine if the case for the Shroud's authenticity should be re-opened. He told the BBC that "With the radiocarbon measurements and with all of the other evidence which we have about the Shroud, there does seem to be a conflict in the interpretation of the different evidence".[86] Professor Ramsey stressed that he would be surprised if the results of the 1988 tests were shown to be far out - especially "a thousand years wrong" – but he insisted that he was keeping an open mind.[87]

    The results of the tests were to form part of a documentary on the Turin Shroud which was to be broadcast on BBC2. The producer of the 2008 documentary, David Rolfe, suggested that the quantity of carbon 14 found on the weave may have been significantly affected by the weather, the conservation methods employed throughout the centuries,[88] as well as the volatile carbon generated by the fire that damaged the shroud while in Savoy custody at Chambéry. Other similar theories include that candle smoke (rich in carbon dioxide) and the volatile carbon molecules produced during the two fires may have altered the carbon content of the cloth, rendering carbon-dating unreliable as a dating tool.[89][90]

    In March 2008 Professor Ramsey reported back on the testing that: "So far the linen samples have been subjected to normal conditions (but with very high concentrations of carbon monoxide). These initial tests show no significant reaction - even though the sensitivity of the measurements is sufficient to detect contamination that would offset the age by less than a single year. This is to be expected and essentially confirms why this sort of contamination has not been considered a serious issue before." He noted that carbon monoxide does not undergo significant reactions with linen which could result in an incorporation of a significant number of CO molecules into the cellulose structure. He also added that there is as yet no direct evidence to suggest the original radiocarbon dates are not accurate. [85]

    The calculations were done incorrectly[edit]
    In 1994, J. A. Christen applied a strong statistical test to the radiocarbon data and concludes that the given age for the shroud is, from a statistical point of view, correct.[91]

    However critics claim to have identified statistical errors in the conclusions published in Nature:[39] including: the actual standard deviation for the Tucson study was 17 years, not 31, as published; the chi-square distribution value is 8.6 rather than 6.4, and the relative significance level (which measures the reliability of the results) is close to 1% - rather than the published 5%, which is the minimum acceptable threshold.[92][93]
