The origin of life on Earth and the conditions under which it may have arisen remain a mystery, due in part to the lack of knowledge about the Earth's environment 4.2 billion years ago and the available chemicals during that time. It is also difficult to imagine the setting of the origin of life to be in a single type of environment or location as a variety of reactions/chemical processes, such as spark discharge, UV irradiation, mineral catalysis, or dehydration-rehydration cycles, likely contributed to the emergence of early life, each of which may have been more favorable in different environmental settings. Thus, the origins of life required a variety of settings: at the bottom of the ocean floor, near hydrothermal vents, or in hot springs, just to name a few. These chemical processes ultimately resulted in the abiotic synthesis of life's building blocks, i.e., amino acids, peptides, ribose, nucleobases, fatty acids, nucleotides, and oligonucleotides, as well as so-called "non-biomolecules" which are not as present in modern biology. The assembly of these components into larger bio-macromolecules and supramolecular structures could have then led to emergence of key biological properties such as replication or homeostasis. One key property of primitive systems that necessarily must have emerged is compartmentalization, which could contribute a variety of functions helpful for a growing/evolving primitive chemical system and could have been achieved by primitive compartments or protocells. Ghosh and colleagues summarize the latest experiments on the characterization and utilization of membraneless coacervates as protocell models in origins of life (OOL) studies. This includes the possibility that coacervates facilitated the transition from membrane-free to membrane-bound compartments, brought together RNA and peptides for coevolution, localized prebiotic metabolites to initiate primitive metabolism, and evolved through growth and division while maintaining an out-of-equilibrium state, each of which could have been important steps in the origin of life. While there are other types of primitive membraneless protocell models, such as aqueous two-phase systems, supercritical carbon dioxide, and polyester microdroplets, we focus on coacervates as membraneless protocell models.
