[Sohu science news] according to foreign media reports, Michael blaber, a structural biologist at Florida State University in the United States, has made an important discovery about the evolution of life, which will help scientists further understand the origin of the original life on earth Michael blaber and his team found that four billion years ago, 10 kinds of amino acids naturally existed on earth could aggregate into proteins and fold in special environments This protein can support the metabolic activity of primary life on earth 3.5-3.9 billion years ago After more than three years of hard work, Michael blaber's team finally got this important result The technology involved in this research has been accumulated for about 17 years The results have been published in the proceedings of the National Academy of Sciences The first amino acids can be formed automatically by simple chemical reactions, then polymerized into proteins, which can fold under appropriate conditions Such protein folding can take place in the environment of high temperature and pressure on the sea floor, such as the deep-sea hydrothermal vent, which may be the stage of the original origin of life "At present, the mainstream view about the origin of life is that RNA first sows the fire of life," blaber said Our research is more inclined to believe that protein is the cornerstone of the origin of life (compile: double helix)
