The Primordial Soup Theory The primordial Soup theory was discovered in 1920. According to the Russian scientist A.I. Oparin and English Geneticist J.B.S. Haldane life started in a warm pond/ocean in a process that took place 3.8 billion years ago. A combination of chemicals made fatty acids which made protein. In this process a molecule was born in the atmosphere. The molecule was energized with lightning and rain making “organic soup”. The first organisms would have to be simple heterotrophs in order to survive. To test this theory Chemist Stanley Miller and Physicist Harold Urey did a famous experiment in 1950. Mixing Methane, Ammonia, Water, and Hydrogen. Then the sparked the mixture to signify lightning. The result was amino acids. The Panspermia Theory The Panspermia theory suggests life seeds came from outer space. The word …show more content…

Linking with the idea of hydrothermal vents being a 'reactor' for RNA hydrothermal vents rely on chemical energy from geothermal vents to sustain a organisms. Swarms of bacteria thrive in this environment which acts as an interface between the high temperature vents and cold oxygenated seawater. The bacteria thrive on gases produced by the vents such as methane and use these chemicals to produce simple organic molecules to support the local ecosystem in a similar way to plants using photosynthesis. Wachtershauser has proposed that a biochemical cycle grew and assembled the first living cell. The Deep Sea Vent Hypothesis In 1977, a recent research by geochemists Eoghan Reeves, Jeff Seewald, and Jill McDermott at Woods Hole Oceanographic Institution (WHOI) is the first to test a fundamental assumption of this ‘metabolism first’ hypothesis. This popular view says simple reaction emerged near ancient seafloor hot springs. These reactions presumably turned a nonliving world to a living one. RNA World
