Evolutionary biology has helped explain the transformation of unicellular organisms to intelligent multicellular organisms. Foundations to Chemistry adapted from Chemistry Matter. Primitive atmosphere and origin of Earth: ii. the origin of life a problem for Some of these proteins would have acted as enzymes , catalyzing (accelerating or propitiating) the synthesis of new nucleoprotein macromolecules, precursors of the genetic material that we know today. This hypothesis was proposed by British scientist J.B.S. It is most satisfactory theory because it has a scientific explanation and has been tested experimentally. Oparin’s heterotrophic theory of the origin of life: a contemporary assessment Antonio Lazcano Miembro de El Colegio Nacional Universidad Nacional Autónoma de México Mexico Moscow 2014 .

Formation of long chains of complex macromolecules under the action of various energy sources, thus achieving complex and indispensable compounds for life: proteins, polysaccharides and nucleic acids. Origins of life. A. I. Oparin Grau, teurer Freund, ist alle Theorie, Und grün des Lebens goldener Baum. The Oparin-Haldane hypothesis is a hypothesis independently developed by two scientists: Russian chemist A.I. widerlegt, für Einzeller erst durch L. Pasteur; sie ist jedoch heute anerkannt für den Beginn des Lebens im Archaikum. The incorporation into the coacervates of nucleic acids allowed inheritance and therefore natural selection, giving rise to life itself in the form of the first autotrophic cells. The "primordial soup" idea came about when Russian scientist Alexander Oparin and English geneticist John Haldane each came up with the idea independently. Darwin's theory of evolution by natural selection opened the way for ... Oparin and Haldane in the early twentieth century developed the idea that chemical reactions on the early Earth could have led to the production of a range of organic compounds, forming a ‘primordial soup’ in which the required building blocks for life would have been present.
