[1] [2] [3] For instance, all organisms are composed of at least one cell that processes hereditary information encoded in genes, which
The preconditions to the development of a living cell like the LUCA are clear enough, though disputed in their details: a habitable world is formed with a supply of minerals and liquid water. Prebiotic synthesis creates a range of simple organic compounds, which are assembled into polymers such as proteins and RNA.
