Document Summary
Option d. 1 origin of life on earth. D. 1. 1 describe four processes needed for the spontaneous origin of life on earth. From that point, evolution and natural selection could work to bring about the diversity of species we have today www. ibscrewed. org. D. 1. 2 outline the experiments of miller and urey into the origin of organic compounds. Miller and urey performed their experiments in 1953, looking at the potential for spontaneous formation of organic compounds. Within their apparatus, they recreated the probable conditions of the earth before life was present. They mixed ammonia, methane and hydrogen gases to create the (cid:858)atmosphere(cid:859). They created electrical discharges and boiled water to simulate lightning and rainfall. The simulation ran for a week, and analysis of the water showed that it now contained many organic compounds, including fifteen of the known amino acids. The results suggest that the spontaneous chemical reactions in earth(cid:859)s atmosphere and water could be enough for the origin of organic compounds. www. ibscrewed. org.
