WebAll life on Earth is composed of cells. Cells have lipid membranes that separate their inner contents, the cytoplasm, from the environment. The lipid membranes allow cells to maintain high concentrations of molecules like nucleotides needed for self-replicating RNAs to function more efficiently. WebThe discovery in the 1970s of bacteria thriving at hydrothermal vents deep beneath the surface of the ocean suggests that bacterial life in the ancient oceans was at least certainly possible. Such bacteria would derive their energy from chemical compounds present in …
