WebbThe idea of origin of life was elaborated in the chemical theory by two· workers independently: a Russian biochemist A.I. Oparin in 1923 and an English biologist J.B.S. Haldane in 1928. It was summarized by Oparin in his book "The Origin· of Life" published as an English edition in 1938 WebbIn the 1920s, Russian scientist Aleksandr Oparin and English scientist J. B. S. Haldane both separately proposed what's now called the Oparin-Haldane hypothesis: that life on Earth could have arisen step-by-step from non-living matter through a process of “gradual chemical evolution.” ^3 3
