- A famous experiment used the chemicals found in the early atmosphere of the earth and added energy from electrical sparks to show that the beaker accumulated the building blocks of life (the monomers, such as amino acids). Is it also important to show that the early earth was able to polymerize these building blocks of life into chains of monomers (polymerization with chemical bonds between monomers)?
