What evidence do we have for the origin of life from inanimate matter? 



  • Oparin and Haldane came up with a hypothesis to support the origin of life .
  • This hypothesis was used by Stanley L. Miller and Harold C. Urey to perform an experiment.
  • In a large flask they added methane, hydrogen and ammonia to mimic the primitive atmosphere (it did not have Oxygen).
  • They took water in a smaller flask to mimic water bodies and heated it so that water entered the larger flask (evaporation).
  • Then an electric spark was created to mimic lightning .
  • This resulted in the formation of organic molecules like amino acids which further form proteins which support living beings .
  • This gives evidence for the origin of life from inanimate matter .
  • This is known as the Urey-Miller Experiment .
