What hypotheses about the origin of life on earth were expressed by A.I. Oparin, J. Haldane, J. Bernal?

A.I. Oparin is a long evolutionary process in which living matter is formed from inanimate matter. In the course of chemical evolution, the simplest organic substances emerged from inorganic substances. J. Haldane – the simplest living systems were formed not on the basis of proteins, but on the basis of nucleic acids. In the course of mutations with the accumulation of useful changes, the function of self-reproduction appeared. J. Bernal – organic substances were formed from the “primary broth” with a catalyst.
