Recently,
two hundred vials of chemicals that were used in a 1950s experiment
concerning the origins of life have been discovered in a laboratory in California,
prompting new tests with regards to the matter.
Half a century ago, chemist Stanley Miller, who was at that
time working on his PhD, tested his ideas about life formation under his mentor
at the University of Chicago Harold Urey’s supervision.
His groundbreaking experiments aimed at creating electric
sparks in a mixture of gases he believed much resembled the Earth’s atmosphere
in the early days of existence.
Miller rose to fame when he found traces of amino acids in
the products that resulted from his tests, the discovery earning him high
praise among scientists.
Amino acids are molecules that stand at the very basis of all
forms of life, which rendered the
chemist’s findings to be rather blown out of proportions, newspapers revealing
back in the 50s that he had recreated life in his lab.
After
having found a number of five amino acids, Miller decided to add hot steam to
the mixture of gases, in order to recreate similar to those in an
erupting volcano conditions.
Jeffrey Bada of the University of California, San Diego,
Stanley Miller’s former student and the one to whom all the latter’s materials were
handed down to, has came across the vials and has performed a series of
tests on them using today’s state-of-the-art technology.
Bada and his team of researchers managed to pinpoint
twenty-two amino acids by analysing the surviving samples from the old
experiments.
Moreover, they reported their studies showed that the gases resulted
from a volcano erupting might have well been at the foundation of life on
Earth, since they all meshed into what is called a prebiotic soup (the
compounds that were present on Earth before life emerged).
