Liquid water plays an active role in shaping molecular evolution during the Origin of Life. Water cycles under a Hadean CO2 atmosphere create fluctuations in the salinity, pH and temperature that drive the replication and evolution of long DNA sequences. The water cycles at the millimeter-scale also affect the assembly, division and selection of coacervate protocells.
