According to a research publication of the journal named Proceedings of the National Academy of Sciences, several mysteries regarding the origin of life on Earth may get a path towards a solution. Numerous theories have tried to explain the underlying mechanism that led to the formation of life on Earth but the majority of these are still struggling to find out a clear answer, and therefore, the search is still on for evidence.
Of late, a group of researchers at Texas A&M University has developed a concept of a physical mechanism that can be the factor responsible for origin as well as an evolution of life on Earth. It is a well-known fact that the primary ‘building blocks of life,’ namely, the amino acids, nucleobases, and sugars are required for sustaining life on Earth but long back during the formation of life on earth, all these used to be in tiny proportions inside the ocean that can hardly create life. It is a question however as to how the building blocks combined to form the long-chain macromolecules.
A model system was created by the researchers as stated by Professor Victor Ugaz at Texas A&M University that mimicked the pore structures in the mineral formations found in a recently unearthed subsea hydrothermal vent. The scientists observed that the fluid flows inside the tiny pores of the model behaved in a manner that can result in ‘bulk homogenization’ of different types of organic molecules inside the vents and simultaneously, the fluids are getting transported to active pore surfaces that catalyze the reaction processes.
This could have happened in the early ocean where the hydrothermal pore networks might have acted in a similar manner thereby acting as a precursor for the dilute molecules to gather together and react to form the bio-macromolecules. This theory not only served as a base for life’s origin on Earth but also proved an athletic standpoint for extraterrestrial life because, in both these places, hydrothermal environments were available in abundance.
