• Resumen

  • The article discusses the origin of life on Earth and the clues that hint at how the organisms arose from inanimate matter. Topics include an in-depth discussion on research by scientists that found a way the genetic molecule RNA could have formed on the early earth from the chemicals present, the goal of scientists to create fully self-replicating artificial organisms in the laboratory, which could lead to an understanding of how life may have begun, and the definition of life itself.
