EXAMPLE Foreword Book of Secrets origin of life offers us a remarkable new analysis of the age-old question: How did life on Earth? Authors in it openly and very clearly discuss the major challenges we face today, scientists in the search for the origin of life. They believe that the current experimental and theoretical research at an impasse, and suggest a different path. Their arguments are compelling, original and concise. outlet malls in florida This book will certainly cause many lively discussions between scientists and laymen. It is very likely that after having her experts familiar with the origin of life research will go a different direction. Modern experimental studies on the origin of life on Earth is now entering the fourth decade of its existence as a starting point for this research is considered pioneering work of Stanley Miller of the early fifties. outlet malls in florida Since the Miller outlet malls in florida received electrical discharge several racemic proteinogenic amino acids have been many similar works. In these experiments, which are to varying degrees so guided. "Simulation paradigm", was observed formation of detectable amounts of most types of biochemical compounds and also various organic microscopic structures, which are assumed to be similar historical antecedents first living cells. outlet malls in florida
This research progam outlet malls in florida can be considered a true sequel Darwin's evolutionary ideas of the last century. Its objective is to find acceptable, widespread mechanisms that gradually and spontaneously formed living matter from relatively simple molecules which are believed to be rife then earth surface.
So far, the results have resulted in a number of scientists to believe that it will be possible to find a natural explanation for the origin of life; some important data, however, this unequivocal conviction into question. Since then, the work was published Biochemical Predestination me more and more Bewildered characteristic feature of many experiments published in this area. Not to mention now about those studies that are more or less similar to the original Miller's work, although they are also breeding grounds for criticism. I mean the experiments that led to elucidate the possible pathways of prebiotic synthesis of certain biologically important organic compounds, such as purines, pyrimidines or polypeptides.
The conditions under which most of the experiments outlet malls in florida performed were artificially simplified in such a way that it really could not relate to any of the specific processes that took place at that time perhaps the earth. Example, if we wanted to find a possible mechanism prebiotic condensation outlet malls in florida of free amino acids to polypeptides, we probably would not add to the reaction mixture, sugars or aldehydes. However, what is the probability that an amino acid (or some other presumed precursors) occurred somewhere on prebiotic earth freely without contaminants, whether in solution or in the solid state? The problem is that if sugars or aldehydes outlet malls in florida are present, would prevent outlet malls in florida the formation of polypeptides. Instead, the interfering cross-reactions between sugars and amino acids provide complex insoluble polymeric material whose relation to chemical evolution is very unclear. The problem described interfering cross-reactions that come into consideration, outlet malls in florida was in many works on chemical pathways of life largely neglected. Possible consequences of such omission deserve careful outlet malls in florida consideration.
Still other aspects of research on the origin of life contributed to my growing disagreement with the theory of chemical evolution. One of them is a huge gap lying between the most complex model system obtained in the laboratory "proto" and simplest outlet malls in florida living cell. Anyone familiar example. The ultrastructure outlet malls in florida and biochemical complexity of the genus Mycoplasma, will seriously question outlet malls in florida the relationship of various laboratory "protobuněk" real historical predecessors cells. In my opinion, the possibility of bridging this gap by mimicking chemical processes, which probably took place on Earth, then, quite small. Another issue, which is difficult to resolve concerns spontaneous formation of optical isomers, which are generally found in living matter, the priority in one of two possible forms (e.g. in proteins are found almost outlet malls in florida exclusively L- and D-amino acids do not, in nucleic acids rather D- than L-sugars).
Despite outlet malls in florida all the tremendous effort, after years spent on resolving this important issue today we are no closer to goal than we were thirty years ago. To conclude this brief list of reasons, which reinforces my distrust of the spontaneous formation of life on Earth mere chemical and physical paths
