Pre-biotic Evolution
Historical Time Line for the Study of Evolution
- von
Helmont [1577-1644] proposes spontaneous
generation
- L Pasteur

- Charles
Darwin[1809-1882] in 1859 proposed the Theory of Evolution
The First Experimental Test -
- M Calvin 1950 tries to initiate origin of life-like chemicals - using
NH4, CO2, H2O, H2 -->HCHO
Formaldehyde in the cyclotron.
- Miller and
Urey 1953 use NH4, CH4, H2O, H2 --> amino acids and variety
of molecules. The key is cyanide which is a synthetic intermediate.
- Sydney Fox and co-workers produce proteins and enzymes in the 1950s.
The key is driving off the side-product water.
