Guest guest Posted March 5, 2006 Report Share Posted March 5, 2006 Molecular History Research Center Why Are Amino Acids Still Found in Fossils? Why is it that amino acids are still found in fossils and are not broken down after hundreds of million of years? It might be natural to expect that amino acids would be found in fossils. But this is only true if the fossils are not too old because amino acids break down with time. According to the Bible, a global flood that distroyed the whole world, took place less than 5000 years ago. So if we take our hints from Scripture, the fossils that were buried during this flood have only been around for 5000 years. Only when we assume the long ages, that hundreds of millions of years have passed since the fossils were buried, do we find the presence of intact amino acids in fossils incredible. This question was faced by evolutionists in the 1950s and 1960s, yet no one ever came up with a viable answer. Amino acids should not be found in fossils. They should survive only a few million years at best (Abelson 1956, 1957). So the question, why are they there? is an extremely important question, it is an enigma! Because all detectable levels of many amino acids are expected to survive only a few million years, some have suggested that these amino acids found in older fossils are not actually from the fossil itself. The presence of amino acids could very well be a recent contamination. This idea makes a lot of sense since the fossils are too old, according to the standard paradigm, to have intact amino acids in them. So various research groups set about trying to investigate the possibility that the amino acid presence of older fossils is really a contamination. Silurian graptolites, which are estimated to be 400-430 million years old by the usual evolutionary conventional age, has been found to contain detectable levels of amino acids that are indeed residual in nature (Florkin 1969). They come from the original proteins when the fossil was buried. Another group have looked at shells as old as Jurassic, 135-180 million year by conventional age, and found that they contain amino acids that are bound as protein and peptides (Akiyama and Wyckoff 1970). So, since the amino acids are part of the protein and peptide structure of the fossil itself, it is clear that the amino acids are residual in nature. The amino acids came from the fossil when it was buried, not by some contamination process later on when the fossil was buried in the ground. Because the evidence was so strong and striking, many started to suggest that the amino acids may survive much longer because they are associated within large macromolecules. The protein molecule would create a local environment that would increase the stability of the amino acids. What they were suggesting was that the fossil matrix somehow holds the amino acid molecules together so they do not spontaneously decompose as would be expected on the basis of their binding energies. As can be seen in the graph to the left or above, the difference in survivability of amino acids that are associated within large macromolecules such as wood, bone, coral and dung, and amino acids that are free in nature; are very small. Most of the points on the graph, whether referring to the free component or an associated component, fit into the same pattern. I think this is amazing! Because the long ages supported by the evolutionary process is not questioned, researchers are forced to try to come up with unlikely possibilities. They are forced to acknowledge that the amino acids must have survived for hundreds of millions of years so now they have to come up with a reason why they are present! The graph above illustrates the evidence concerning the racemization of various amino acids suggesting that the variation of amino acid levels found in fossils is due to factors such as heat and not their differences in ages. See my Amino Acid Dating page to hear more. Another issue, very similar to the question why amino acids are still found in fossils, Concerns DNA. Why is DNA still present in fossils? There is even the presence of DNA and bacterial spores in fossils which are still viable! Bacterial have been grown up from fossils that are thought to be hundreds of millions of years old! DNA Raul J. Cano and Monica K. Borucki have discovered and have actually revived (brought back to life!) over 1,000 types of bacteria and other microorganisms. Some of the life-forms date as far back as 135 million years which was the time of the dinosaurs. Can DNA survive that long? Many point to the plain physics of degrading DNA over time and state that organisms cannot survive for millions of years without having the bases of the DNA, which constitutes the genetic code, degrade to such an extent that the organisms would no longer be viable. So, is the presence of amber preserved DNA that is still capable of producing viable bacteria and other microorganisms, evidence that the specimen is in fact very young? That is hard to say. There are many who dismiss all claims of ancient bacteria as modern contamination. Others, however seem to dismiss the problems that the effect of time has on DNA and say, 'It must have survived, because here it is'. Neither group entertains the thought that the time factor might be off several orders of magnitude. Of course the story of Noah in the Bible suggests that these organisms were buried during the global flood, less than 6000 years ago. The young age of the specimens would allow the DNA to still have its original code largely unaffected by time. For an interesting introduction to this topic read the news article "Ancient Bacteria Brought Back to Life" by R. Monastersky in Science News Volume 147, Number 20, May 20, 1995, p. 308. Another interesting article: "Prehistoric bacteria revived from buried salt" by J. Travis in Science News Volume 155, June 12, 1999, p. 373. In this article, J. Travis has interviewed such men as William D. Rosenzweig and Russell H. Vreeland of Penn. University who have now announced to have isolated and revived bacteria from salt deposits that is 250 million years old. Also in the paper, a researcher is mentioned, who is said to have been ahead of his time claimed, back in the 1960s, to have revived bacillus and other bacteria from salt deposits more than 500 million years old. So now we have bacterial spores lasting for 250 million years and maybe as long as 500 million years. Is that possible? You can be sure that this debate over viable fossil DNA will persist. I especially like what Melanie R. Mormile from the Pacific Northwest National Laboratory in Richland, Wash. said: (I must tell you that Melanie has herself reported salt-derived microbes of at least 97 million years old in age) "Whenever anyone claims they have revived organisms that are millions of years old, she says, you've got to sit back and go, 'Wow, that's incredible. How can that be?' " I think this is amazing! Because the long ages supported by the evolutionary process is not questioned, researchers are forced to try to come up with unlikely possibilities. They are forced to acknowledge that the DNA must have survived for hundreds of millions of years so now they have to come up with a reason why they are present!
