Abstract

Why and how our living-bodies, such as human beings, have been originated from a barely non-life planet into the highly-intelligent life existing Earth have been interested and pursued by large population of readers and investigators. Apart from evolution of Darwin’s arguments, [1]some detailed evolutionary theories and steps have been stated and discussed by modern evolutionists and investigators, including the evolutionary step of first genetic information duplication. There has been DNA-, RNA- and protein-originated evolution hypotheses regarding the first genetic information having been duplicated and translated. There were lot of experimental data can be used to support two possibilities of genetic material duplication. For example, we simulate genetic information duplication in the presence of one type of genetic materials. But this likes “chicken-or-the-egg” dilemma concerning which genetic polymer comes first and we cannot tell which is true [2]. Since genetic information duplication is the foremost important step to copy a life with integrity and persistency, it is widely accepted that this process is a crucial step in evolution progression for life creation. In this article, we try to overview these hypotheses and discuss one of the crucial factors for evolution, formation rate or turnover speeds of different genetic materials (DNA, RNA and protein), to further suggest an important role RNA may take in life origin on Earth. Also, we try to discuss one of strategies of justifying these hypothesis and theory of whether through DNA, RNA, or protein-based lifeevolution by using simulating system of different “prehistoric broths” and discover their relations by simulated calculations.
