Volcanic lightning may have sparked life on Earth

One of the most famous experiments of all time has just been found to have been even more successful than anyone realised. The Miller-Urey spark flask experiment could hold the key to the origin of life on Earth.

Jeffrey Bada of the Scripps Institution of Oceanography in California and colleagues re-analysed the original 50-year-old samples left by Stanley Miller of the University of Chicago, in 1953 and 1954. His was the first experiment ever to produce amino acids, the building blocks of proteins, from inorganic molecules and a spark of electricity.

Bada’s team discovered more organic molecules than Miller had been able to detect, and also showed that a secondary experiment – one that Miller carried out but never published – offers the best clue to how life on Earth began some 4 billion years ago.

  1. We cannot know the origin of life – we can only theorize about it.

    Whereas we do know the origins of violence, abuse and psychotic control. Best to spend the money wasted on the search for origins in dealing with the REAL issues facing us as people, as communitys and as humanity.

  2. Common on, the Earth and Heavens are only 6-10 thousand years old, ya know, don’t use science hocus pocus to confuse the mass’.
