[QUOTE]Originally posted by glassman: [QB] volcanoes may be the real reason we are here at all: [b] The Volcanic Origin of Life By Michael Schirber, LiveScience Staff Writer posted: 05 November, 2004 8:00 a.m. ET How the primitive Earth cooked up proteins is a chemical mystery. These molecules - vital to biological functions - are made of long strands of hundreds of amino acids, but researchers are unclear how even some of the shortest amino acid chains, called peptides, formed prior to the dawn of living organisms. Recent experiments have demonstrated how a volcanic gas, carbonyl sulfide (COS), may have been instrumental in the "prebiotic" build-up of peptides. There are several mechanisms for connecting amino acids. Organisms use enzymes, and chemists have identified other catalysts that can do the job. However, Leslie Orgel from the Salk Institute points out that few of these things were ingredients of Earth's environment billions of years ago. "With carbonyl sulfide, we have a very realistic agent," Orgel said. This gas is known to fume out of volcanoes today and was likely present in the planet's fiery past. [/b] the Hawaiians mythology gives credit for all of creation to Pele the Goddess of the volcano. In Roman mythology, Vulcan, the god of fire, was said to have made tools and weapons for the other gods in his workshop at Olympus. [/QB][/QUOTE]
