This energy, he theorized, provided the necessary activation energy for chemical reactions to occur, leading to the formation of more complex organic molecules from simpler inorganic ones. This process is known as abiogenesis, the origin of life from non-living matter.
Oparin's theory, along with similar ideas by J.B.S. Haldane, formed the basis for the primordial soup hypothesis. This hypothesis suggests that the early Earth's atmosphere contained a reducing atmosphere rich in methane, ammonia, and hydrogen, which could have reacted to form the building blocks of life in a "soup" of organic molecules in the oceans.
While Oparin's theory has been influential, it's important to note that the exact conditions and mechanisms of abiogenesis are still not fully understood. Current research explores other possibilities, such as the role of hydrothermal vents and the formation of life on other surfaces like clay minerals.
