"Some people have no direction because they don't know the science of themselves. The science of life is the science of you; all the elements it took to create you, cause everything in the universe that's created the universe exists within you. That's the mind that you can't see."~Popa Wu The scientist Steve Grand wrote the following: "Think of an experience from your childhood. Something you remember clearly, something you can see, feel, maybe even smell, as if you were really there. After all, you really were there at the time, weren't you? How else would you remember it? But here is the bombshell: you weren't there. Not a single atom that is your body today was there when that event took place.... Matter flows from place to place and momentarily comes together to be you. Whatever you are, therefore, you are not the stuff of which you are made. I believe that success is most accurately measured by qualitative achievements contributing to the betterment of humanity on some level, even if only on the tiniest of scales. I admonish the prevalent concept of quantitative comparisons in relation to others as a form of elitism that impedes the progress of society and the evolution of individuals within a culture. True knowledge is power. It is the sharing of thoughts and ideas combined with selfless service to others that lead to the greatest innovations. Any closed system that reinforces the separation of people (blind belief systems, class systems, etc) is ultimately an unreality that needs to be seriously re-evaluated if we as a people are to enjoy the prosperity and abundance that we can provide for ourselves and for each other as creative beings in an elegantly beautiful world. One odd feature of organic chemistry is the principle of chirality. Chirality describes the two isomer, D and L, which are mirror images of one another and rotate the plane of light in opposite ways. Nature is very asymmetric, and natural selection has chosen particular isomers to represent the population of entire molecular systems based on evolutionary advantages. Amino acids constituting living systems are all L-isomers, while ribose and deoxyribose (the backbone sugars of RNA and DNA, respectively), are all D-isomers by nature. Considering that nature will always produce racemic mixtures (equal amounts of L and D isomers), there had to have been an original achiral molecule which evolved in time to express the homochirality of the modern proteins and nucleotides. Such an achiral polymer that could have been produced in the prebiotic environment was discovered and isolated by Peter Nielson and named "PNA"(peptide-nucleic acid). PNA is a hybrid of nucleic acids and proteins with a peptide backbone attaching nucleic acid bases. The protein backbone consists of the only one out of 20 organic amino acids, glycine, that is not chiral and has no isomers, so it can form in nature and and generate base pairs in a similar way to RNA without having to copy "un-natural" homochiral isomers. The PNA polymers were the likely precursors to RNA, which has the advantage over DNA in being able to catalyze its own metabolic functions without the requirement of protein enzymes, and the fact that it is composed of simpler building blocks than DNA. Moreover, RNA can join together regardless of chirality in a mechanism known as template-directed ligation which likely guided the early evolution of RNA sequence copying. Once proteins evolved as strong catalysts with high specificity for their particular substrates, protein enzymes were then selected over ribozymes to perform most of the metabolic duties of the cell and aid in the conversion of RNA to DNA, which then became the most specialized carrier of genetic information. The interplay of RNA, DNA and proteins allowed for the evolution of more and more complex pathways over time for the most efficient use of energy on a cellular level. "I never hate--that's just wasted energy. The past is gone. The present is a gift, so what's the mystery?--The future. Time only reveals what fear is...False Expectations Appearing Real. We're only human. Love thy neighbor so I was told and I will until permanently my eyes are closed."--Nas
.. The theory behind evolution is the mechanism of natural selection. Evolution, in itself, is factual. A theory is only an explanation to corroborate the facts with what is causing it to occur. A theory starts as a hypothesis, and when it withstands all scrutiny from other scientists looking for just one thing that would falsify it and render it meaningless, then and only then can you call it a theory that matches observable reality. Then, the more information we gain from continuing to ask questions, the more we can expand the theory from its original framework and start uncovering a greater piece of reality that can be explained by answering the new questions raised from the old answers. ..........
