Another famous area of evolutionary experimentation has been in trying to produce life (or at least the precursors of life) from chemicals. It is interesting that the most widely referenced chemical evolution experiment found in textbooks today is still the Stanley Miller experiment from the 1950’s. Evidently not much progress has been made in the last 50 years! However, this experiment produced only a few amino acids, and had many problems associated with it, some of which are given on the slide.
