Abstract All living beings use the same genetic code; hence they derive from a common ancestor. Carbonaceous meteorites and comets contain organic matter, whose carbon isotopic signature points to an abiotic origin. However, these extraterrestrial precursor molecules of life never reach the complexity of the large molecules of living ...

Previous Entry iconEncyclopedia Next Entry The origin of life remains today one of the most challenging puzzles to science. The challenge is twofold: (1) qualify the essence of life and (2) explain its appearance on Earth. Although both aspects have been subject to much scientific investigation, no satisfactory explanation has been formulated so far.
