where hot/cold, wet/dry cycles readily occur Tide pools in the ocean. Hydrothermal vents with hot/cold, wet dry cycles Volcanic hot springs pools Organic molecule readily polymerize into complex chains in the right conditions (heating, chilling, drying, etc.). Also in solution organic molecules will combine into droplets simulating some cellular activities. But a cell has yet to be created. The sequence that has been suggested is this one Where this occurred on Earth is not known but an organic soup of molecules might have developed in puddles along the primordial sea. Recently, it has been suggested that the right conditions might have been in hydrothermal vents in the ocean. The key step in this process was the development of molecules that could reproduce themselves like DNA or RNA. Once that occurred then natural selection would have followed; molecules that could best survive and compete of nutrients (building blocks) would best leave copies of themselves. RNA has been suggested as being most likely to have been the first self-replicator; it is smaller and (it promotes the production of more of itself). DNA is much larger and thus more complex and more stable. Terms/Concepts to Define Big Bang Theory Stromatolites Chemical Fossils Divine Creation Panspermia Directed Panspermia Spontaneous Generation
