Document Summary

Oparin, haldane hypothesis (1920s) the early earth conditions, heat and toxins would be the perfect chemical soup that would make amino acids and nucleic acids. Set up basic molecules in the early earth"s environment with an atmosphere and ocean. Miller gets amino and nucleic acids almost immediately and every time it has been run has given the same result. Experiment criticized because of boiling ocean and electricity/ heat that came from the coil may not be exactly correct. The fact that it is that easy though proves that it may be right. Rna can store information and it has catalytic activity. Spiegelman - got viral rna to self replicate in a lab - these test have been replicated and. It is inert and we can isolate rna from ancient caveman had the same outcome over and over again. Stromatolites - form mushrooms that build on top of each other they are living and we still have them now.
