Resum

Stanley Miller is best known for his classic 1953 experiment on organic compound synthesis on the early Earth in the context of the origins of life. However, he did several other experiments that are lesser known and in some cases never published. The finding in 2007 that Miller had archived dried solutions from his 1950s experiments offered the opportunity to analyse the products of his early experiments using modern day state-of-the-art techniques. These results along with Miller’s results, have provided an inventory of the large variety of compounds, that include amino acids, amines, simple peptides, hydroxy acids, simple hydrocarbons and 1urea, that can be synthesized under simulated early Earth conditions.

Jeff L. Bada, University of California, San Diego

Jeffrey Bada is a Distinguished Research Professor, and Distinguished Professor Emeritus, of Marine Chemistry at the Scripps Institution of Oceanography, University of California, San Diego. He obtained his PhD in Chemistry at UCSD in 1968 where Stanley Miller supervised his thesis research. His research deals with the environments on the early Earth that provided the optimal conditions for the synthesis of organic compounds required for the origin of life
