The MillerUrey Experiment
In 1952 chemists Stanley Miller and Harold Urey performed an experiment
to try and discover how life was formed by recreating the conditions of the
early earth. They did this by placing a mixture of water, ammonia ,methane
and hydrogen this was then heated to create water vapour. Electric sparks,
representing lightning, were passed through the water vapour and gases.
After a week, the results collected and 11 different amino acids ( the
beginnings of protein) were found , they froze this mixture and when it was
reanalysed in 2008 and 22 different amino acids were found. This
experiment supported the theory of a `primordial soup' the idea the
chemicals needed to support life where able to develop naturally on the
early earth.
