Thinking about these familiar roles led me to a question: Could their differences partly reflect the different physical and chemical environments in which early life developed?
I wondered whether the organization of ecosystems might offer a useful starting point for thinking about life's beginnings. This question connects with a theme running through my research. I have studied soil colloids, biological membranes, radiation-induced reactions, and the movement of trace substances in the environment.
Across these subjects, I have become increasingly interested in how environmental structures influence what molecules do. Interfaces, gradients, barriers, and flows affect where substances accumulate, which reactions occur, and whether their products remain available. In my paper published in The Science of Nature, I bring this perspective to the origin of life.
I explore whether different environments could have supported complementary chemical functions, and whether exchanges between them helped those functions become connected. Hydrothermal vents are compelling candidates for life's beginnings. Interactions between water and rock can supply chemical energy, reactive minerals, and conditions that support organic synthesis.
Hydrothermal pores may also concentrate molecules, while cooler mixing zones offer conditions different from those in hot vent fluids. I am interested in how these varied conditions affect the fate of reaction products. Making a useful molecule is one step.
Keeping it available for another reaction is another. A product may accumulate, attach to a mineral surface, move elsewhere, or break down. Breakdown also deserves attention.
