Miller-Urey Experiment Revisited

by Irma Arkus

New York Times’ Kenneth Chang reports on efforts in University of Chicago, where Miller-Urey experiments conducted in 1950s proved that simple amino acids can be created under certain environmental conditions, thus proving that proteins necessary for creation of life can spontaneously and naturally arise, have been revisited.

No, they have not reenacted the Miller-Urey experiments, as much as revisiting original test-tubes from the 1953 experimentation, yielding surprising results. Analysis of hundred of vials filled with dried residues identified much higher quantity of amino acids than initially detected by Dr. Miller.

This adds to the scientific theories of how life on Earth began, as current theories indicate the required amino acids originated in space, as detected in meteorites, or bottom of the ocean, or better yet, warm tidal pools subjected to rains and volcanic steam.
