7. "primordial soup theory"
• John Burdon Sanderson Haldane independently arrived at
similar conclusion in 1929 and gave the name "soup" to the
theory.
8. Stanley Miller and Harold Urey used a highly reduced
mixture of gases—methane, ammonia and hydrogen—to
form basic organic monomers, such as amino acids.
