Origin of Life
Theories for the origin of life has been around since the beginning of civilization. However, It was Charles Darwin who first introduced a biologically possible theory that is still intact today. Darwin suggested that life grew in a "warm little pond" of organic chemicals that, over a long period of time, gave life to the first organisms. As this theory evolved, the pond became an ocean. In a breakthrough experiment conducted by Stanley Miller in 1953, the first reasonable experimental evidence for Darwin's theory was developed. This evidence lay in a glass jar, in which a simplified version of earth in its infancy was created. Using water, ammonia, hydrogen and electrical discharge, Miller created organic chemicals, including a large quantity of amino acids. Although Miller's experiment presented the building blocks of proteins, many current researchers believe that a larger molecule - RNA - came before proteins. Meanwhile older fossils and organisms in oceanic hot springs contradict Darwin's vision of a peaceful evolution.
Around 4.5 billion years ago, the solar system was composed of merely gas and dust. Planets were created by
