One of the foremost experiments of the twentieth century : Stanley Miller and the origin of prebiotic chemistry
Stanley Miller is best known for his classic 1953 experiment on the synthesis of early Earth organic compounds, in the context of the origins of life. However, he did several other experiments that are lesser known and, in some cases, have never been published. The finding in 2007 that Miller had archived dried solutions from his 1950s experiments offered the opportunity of analyzing 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 urea, which can be synthesized un…
Charles Darwin and the Origin of Life
When Charles Darwin published The Origin of Species 150 years ago he consciously avoided discussing the origin of life. However, analysis of some other texts written by Darwin, and of the correspondence he exchanged with friends and colleagues demonstrates that he took for granted the possibility of a natural emergence of the first life forms. As shown by notes from the pages he excised from his private notebooks, as early as 1837 Darwin was convinced that “the intimate relation of Life with laws of chemical combination, & the universality of latter render spontaneous generation not improbable”. Like many of his contemporaries, Darwin rejected the idea that putrefaction of preexisting organ…
