Document Summary
Miller"s experiment: can simple molecules and kinetic energy lead to chemical evolution: attempted to produce microcosm of ancient earth, large flask represented atmosphere with methane gas, ammonia and hydrogen with high free energy, large flask was connected to small flask by glass tubing, small flask had 200ml of water (tiny ocean, to connect mini atmosphere with mini ocean, miller boiled the water constantly, this added water vapour to the mix of gases in the large flask, water vapour circulated through the system, formed simulated version of the prebiotic soup, miller sent electrical discharges across the electrodes he"d inserted into the atmosphere, mini lightning bolts occurred, after a day of boiling and sparking the solution began to turn pink, after a week it was deep red and cloudy, miller found large quantities of hydrogen cynaide and formaldehyde in the mini ocean.
