    Haldane introduced the modern concept of abiogenesis in an eight-page article titled The origin of life, in the Rationalist Annual in 1929, describing the primitive ocean as a "vast chemical laboratory" containing a mixture of inorganic compounds – like a "hot dilute soup" … Alexander Ivanovich Oparin (Александр Иванович Опарин; March 2 [O.S. February 18] 1894 – April 21, 1980) was a Soviet biochemist notable for his theories about the origin of life, and for his book The Origin of Life.

Haldane and Russian biochemist Aleksandr Oparin independently set forth similar ideas concerning the conditions required for the origin of life on Earth.

    The origin of life on Earth is a scientific problem which is not yet solved. There are many ideas, but few clear facts.. Most experts agree that all life today evolved by common descent from a single primitive lifeform. It is not known how this early form first lived, but scientists think it was a natural process which happened about 3,900 million years ago. Origin and evolution of life 1. Origin and evolution of life Origin of life : Theories of the origin of life, early earth, modern self assembly theories, Oparin-Haldane theory of chemical evolution of life. Organic evolution : Darwin’s theory, modern synthesis theory of evolution, geological time scale.

    The origin of life on Earth could have resulted from asteroid impacts, carrying life forms and molecules from far away planets and even from different solar systems (Figure 4.209).The Murchison meteorite (carbonaceous chondrite), that came down in 1969 in Australia, demonstrates the validity of such a type of interplanetary transportation mechanism. Origin of Life:: A. Chemogeny (Chemical Evolution) B. Biogeny (Formation of Primitive Life) C. Cognogeny (Nature of Primitive Life and Its Evolution). Modern Theory of Origin of Life was proposed by a Russian biochemist, Alexander I. Oparin (1923 A.D.) and was supported by a British scientist, J.B.S. Haldane (1928 A.D.), so is also called
