PRIMORDIAL SOUP

The Miller-Urey experiment about the origin of life has been included in a lot of textbooks published in the last fifty years, because that experiment was an innovator discovery at that time. Stanley Miller was a student at the University of Chicago and Harold Urey was his graduate advisor.

The experiment was called “The primordial soup”, because Miller and Urey tried to create the chemical evolution process that generated life in our planet. The experiment consisted of mixing some chemical elements such as methane, hydrogen, and ammonia, then, they heated that mixture in order to evaporate it.

The main point here is that, Miller an Urey with that experiment tried to re-create the atmosphere in which life was generated, and they believe that the amino acids that they created in the laboratory were similar to the chemical mixture of the early earth.

However, there are several objections that we have to consider before. First, the laboratory’s atmosphere, we do not know if the electric charges were continuous as the Miller and Urey used.

Second, some scientist think that the oxygen was reduced in the Miller and Urey’s experiment, so the amount of amino acids was too high as the early earth one.
