Miller-Urey experiment. Computer illustration showing the apparatus used in the Miller-Urey experiment to study the origin of life. This 1950s experiment attempted to duplicate the conditions that would have existed on the primordial Earth. The apparatus contains a 'sea' of sterile water (bottom) and an 'atmosphere' of hydrogen,methane and ammonia (top right). Electrodes give off a spark within the 'atmosphere' to imitate either lightning or ultra-violet radiation from the Sun. The result is a tar-like residue containing amino acids,the basic building blocks of life | |
