There are many hypotheses trying to explain the origin and development of life on our planet. And although they offer different approaches to solving this problem, most of them suggest the presence of three evolutionary stages: chemical, prebiological and biological evolution. At the stage of chemical evolution, abiogenic synthesis of organic polymers took place. At the second stage, protein-nuclein-lipoid complexes were formed (scientists called them differently: coacervates, hypercycles, probions, progenotes, etc.) capable of orderly metabolism and self-reproduction. As a result of prebiological natural selection, the first primitive living organisms appeared, which entered into biological natural selection and gave rise to the whole diversity of organic life on Earth.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
