Stegosaurus at Angkor wat from 800 years ago
An article in "Nature" entitled "Twisted structure preserved dinosaur proteins" discusses one such attempt. "Scientists have discovered how fragments of the protein collagen might have survived in fossilized dinosaur bones. The intertwining, rope-like structure of the molecule, a major component of bone, could have shielded parts of the protein from enzymes and the elements for tens of millions of years, they say. The results, which are published in PLoS ONE1, support the contentious claim that dinosaur proteins have been recovered and sequenced..." The article continues: "The study is "interesting and plausible, but speculative", says Marshall Bern, a computer scientist at Palo Alto Research Center in California, who has also analysed dinosaur-protein data. "It's hard to extrapolate too far from the little bit of sequence that has been found," he says."
Stephen Salzburg is having none of it as he knows that it is impossible for collagen to survive such a long time. However he too cannot accept the obvious conclusion and has to false back on a equally dubious solution to the dilemma- that the collagen is contaminates from modern species. "...Others are more sceptical. Stephen Salzberg, a geneticist at the University of Maryland in College Park, has already posted a critical comment about the paper at PLoS ONE, saying that the peptides that the team analysed "are contaminants from modern species"...Salzberg says that the oldest verified proteins are bacterial molecules hundreds of thousands of years old found in ice cores. The dinosaur bones are many times older than that, and were found in temperate Idaho. Theoretical predictions and lab experiments suggest that proteins cannot survive for more than a few million years..."
In fact other evolutionary scientists have stated that blood collagen cannot survive much past 30,000 years. Mary Schweitzer who also believes in the evolutionary dating of the dinosaurs disagrees with Salzburg. "...But Schweitzer, who also contributed to the latest study, counters that if the collagen fragments were contaminants, they should have come from random parts of the structure. Instead, they all came from the most protected parts of the microfibril, supporting the idea that they are genuine dinosaur relics...Schweitzer notes that her claims have been supported by two labs besides her own3. Furthermore, no collagen was found in sediments around the fossils, as would have been expected if the molecules were contaminants; and the team got positive results when testing the samples using antibodies that stick to collagen and other bone proteins. As well as telling us how dinosaurs lived, Schweitzer believes that work on their proteins could inform the design of more effective and resilient collagen for use in prostheses or medical implants..."
Both Salzburg and Schweitzer are right on their area of expertise based on scientific evidence, where both of them go wrong is accepting the fantasies of evolutionary theorist and philosophers about the ages of the dinosaur fossils. How long will these scientist continue to remain blind to the truth- that evolution is a theory that has passed its used by date.
