Prebiotic Chemistry and the Legacy of Stanley Miller's Groundbreaking Experiment

Stanley Miller, a pioneer in prebiotic chemistry, conducted a landmark experiment in 1953 demonstrating the formation of simple organic molecules under conditions simulating early Earth. His experiment used water, methane, ammonia, and a spark to mimic lightning. Upon retirement, Miller's samples were passed to Jeffrey Beda, who discovered unexamined samples in 2007. Recent studies revealed that introducing cyanamide can link amino acids into peptides, advancing our understanding of chemical evolution and the origins of life.
