Volcanoes may have provided sparks and chemistry for first life

"Stanley and I continued to work on various projects until he died in 2007. When Adam and I found the samples from the original experiments, it was a great opportunity to reanalyze these historic samples using modern methods," said Bada. The team wanted to see if modern equipment could discover chemicals that could not be detected with the techniques of the 1950s. They analyzed the samples and turned to Daniel Glavin and Jason Dworkin of NASA's Goddard Space Flight Center in Greenbelt, Md., who helped the analysis with state-of-the-art instruments in their Goddard Astrobiology Analytical lab.

Miller actually ran three slightly different experiments, one of which injected steam into the gas to simulate conditions in the cloud of an erupting volcano. "We found that in comparison to Miller's classic design everyone is familiar with from textbooks, samples from the volcanic apparatus produced a wider variety of compounds," said Bada.

"We discovered 22 amino acids, 10 of which have never been found in any other experiment like this," said Glavin. This is significant because thinking on the composition of Earth's early atmosphere has changed. Instead of being heavily laden with hydrogen, methane, and ammonia, many scientists now believe Earth's ancient atmosphere was mostly carbon dioxide, carbon monoxide, and nitrogen.

"At first glance, if Earth's early atmosphere had little of the molecules used in Miller's classic experiment, it becomes difficult to see how life could begin using a similar process. However, in addition to water and carbon dioxide, volcanic eruptions also release hydrogen and methane gases. Volcanic clouds are also filled with lightning, since collisions between volcanic ash and ice particles generate electric charge. Since the young Earth was still hot from its formation, volcanoes were probably quite common then. The organic precursors for life could have been produced locall
