http://en.wikipedia.org/wiki/Miller-Urey_experiment

The Miller-Urey experiment (or Urey-Miller experiment) was an experiment that simulated hypothetical conditions present on the early Earth and tested for the occurrence of chemical evolution. Specifically, the experiment tested Oparin and Haldane's hypothesis that conditions on the primitive Earth favored chemical reactions that synthesized organic compounds from inorganic precursors. Considered to be the classic experiment on the origin of life, it was conducted in 1953 by Stanley L. Miller and Harold C. Urey at the University of Chicago.

At the end of one week of continuous operation Miller and Urey observed that as much as 10-15% of the carbon within the system was now in the form of organic compounds. Two percent of the carbon had formed amino acids, including 13 of the 22 that are used to make proteins in living cells, with glycine as the most abundant. Sugars, lipids, and some of the building blocks for nucleic acids were also formed. Nucleic acids (DNA, RNA) themselves were not formed. As observed in all consequent experiments, both left-handed (L) and right-handed (D) optical isomers were created in a racemic mixture.
